Randomized crossover clinical trial of a Mindfulness-based intervention for nurse leaders: A pilot study / Ensayo clínico aleatorizado cruzado de una intervención basada en mindfulness con enfermeros líderes: estudio piloto / Ensaio clínico randomizado cruzado de uma intervenção baseada em mindfulness em enfermeiros líderes: estudo-piloto

Objective: to analyze the effects of a Mindfulness-based intervention on nurse leaders' emotional intelligence and resilience. Method: a pilot study of a randomized crossover clinical trial. The sample (n=32) was randomized into Group A (n=18) and Group B (n=14) and evaluated at the pre-test, post-test and follow-up moments. The outcomes were assessed using the Emotional Intelligence Measure, the Connor-Davidson Resilience Questionnaire and the Five Facet Mindfulness Questionnaire, and analyzed using Generalized Linear Mixed Models. Results: a total of 32 nurses with a mean age of 42.6 years old were evaluated. The analyses showed significant interactions between the effects of the group x moment factors on the Self-motivation (p=0.005), Sociability (p<0.001), Self-control (p=0.013), and Total (p=0.002) emotional intelligence skill scores; as well as on the Observe (p=0.042), Describe (p=0.008), Non-judgment (p<0.001), Act with awareness (p=0.004) and Total (p<0.001) mindfulness facets. Post-test: there was a statistically significant increase in the Sociability (p=0.009) and Self-control (p=0.015) emotional intelligence skills; as well as in the Non-judgment (p=0.022) and Total (p=0.002) mindfulness facets. Follow-up: a significant increase was observed in the Non-judgment (p=0.024) and Total (p=0.026) mindfulness facets. The "resilience" variable did not present statistical significance in the "group x moment" factor, both in the post-test and during follow-up. Conclusion: the Mindfulness-based intervention used proved to be effective in increasing nurse leaders' emotional intelligence and dispositional mindfulness skills.

Eficácia de uma intervenção online para prevenção da ansiedade: um ensaio clínico / Efectividad de una intervención online para prevención de ansiedad: un ensayo clínico / Efficacy of an online intervention for anxiety prevention: a clinical trial

The purpose of this study was to test the effectiveness, and the sustained effect (follow-up) of a fourweek mindfulness intervention in reducing anxiety and stress in a group of Brazilian university students, the intervention was adapted to be made available through the application Neurosaúde, created as part of this work to serve as a platform for intervention. The research as a whole took place in a virtual environment, with forty-eight participants recruited who were randomly allocated to the intervention group or to the waiting list control. Measures were used to access the levels of mindfulness, anxiety and stress before, after the intervention and at the 4-week follow-up. Applying the intention-to-treat analysis, we found significant differences between the groups for the measurement of anxiety in the follow-up with a large feat size (F (2.92) = 10.275, p = 0.000, η2 = 0.183). Our results suggest that the 4-week mindfulness intervention through a mobile application was able to act as a protective factor against the anxiety developed by university students during the occurrence of the pandemic caused by Covid-19, whereas while the treatment group maintained levels reduced anxiety the control group demonstrated a continuous increase in anxiety in the post-test and follow-up that coincided with the first wave of Covid-19 in the region where the participants lived.

El propósito de este estudio fue probar la eficacia y el efecto sostenido (seguimiento) de una intervención de atención plena de cuatro semanas para reducir la ansiedad y el estrés en un grupo de estudiantes universitarios brasileños, la intervención se adaptó para estar disponible a través del app. Neurosaúde, creada como parte de este trabajo para servir como plataforma de intervención. La investigación en su conjunto se llevó a cabo en un entorno virtual, siendo reclutados cuarenta y ocho participantes que fueron asignados aleatoriamente al grupo de intervención o al control en lista de espera. Se utilizaron medidas para evaluar los niveles de atención plena, ansiedad y estrés antes, después de la intervención y en el seguimiento a las 4 semanas. Al aplicar el análisis por intención de tratar, encontramos diferencias significativas entre los grupos para la medida de ansiedad en el seguimiento con un tamaño de efecto grande (F (2.92) = 10.275, p = 0.000, η2 = 0.183). Nuestros resultados sugieren que la intervención de mindfulness de 4 semanas a través de una aplicación móvil fue capaz de actuar como factor protector contra la ansiedad desarrollada por estudiantes universitarios durante la ocurrencia de la pandemia de Covid-19, ya que mientras el grupo de tratamiento mantuvo niveles, el grupo control demostró un aumento continuo de la ansiedad en el postest y seguimiento que coincidió con la primera ola de Covid-19 en la región donde residían los participantes.

A intervenção foi adaptada para ser disponibilizada pelo aplicativo Neurosaúde, criado como parte deste trabalho para servir de plataforma para a intervenção. A pesquisa como um todo ocorreu em ambiente virtual, sendo recrutados 48 participantes que foram alocados randomicamente para o grupo intervenção ou para o controle de lista de espera. Medidas foram utilizadas para acessar os níveis de mindfulness, ansiedade e estresse antes, após a intervenção e no follow-up de quatro semanas. Aplicando a análise por intenção de tratar, encontramos diferenças significativas entre os grupos para a medida de ansiedade no follow-up com um tamanho de efeito grande (F (2.92) = 10.275, p = 0.000, η2 = 0.183). Nossos resultados sugerem que a intervenção de mindfulness de quatro semanas por meio de um aplicativo móvel foi capaz de agir como um fator protetor contra a ansiedade desenvolvida pelos estudantes universitários durante a ocorrência da pandemia causada pelo Covid-19, visto que, enquanto o grupo tratamento manteve níveis reduzidos de ansiedade, o grupo controle demonstrou um contínuo aumento de ansiedade no pós-teste e follow-up que coincidiu com a primeira onda de Covid-19 na região onde os participantes residiam.

Effectiveness evaluation of online Mindfulness in mental health and alcohol consumption in medical students during the COVID-19 pandemic / Evaluación de la eficacia del Mindfulness online en la salud mental y el consumo de alcohol en estudiantes de medicina durante la pandemia de COVID-19

Abstract Introduction As a result of the COVID-19 pandemic, the prevalence of stress, anxiety, depression, and alcohol consumption has increased among medical students. Mindfulness is an intervention to decrease these psychopathologies and alcohol consumption; however, evidence has shown unclear results regarding its efficacy. Objective To evaluate the effectiveness of an online Mindfulness-based intervention (MBI) on stress, anxiety, and depression symptomatology levels, as well as on alcohol consumption and mindfulness status in medical students during the COVID-19 pandemic. Method A quasi-experimental study was conducted on 237 students, obtaining sociodemographic data. In addition the levels of psychopathology, alcohol consumption, and state of mindfulness: were measured pre-and post-intervention through the DASS-21, AUDIT, and MASS instruments. Eight online Mindfulness sessions were conducted once a week for approximately one hour each. Results MBI did not reduce levels of psychopathologies or alcohol consumption, nor did the mindfulness status improve. High levels of psychopathologies, dropout rate, and lack of voluntary participation were the main factors limiting the effectiveness of the online MBI. Discussion and conclusion The online MBI wasn't effective among the population under study: we recommend generation strategies where students are involved in and complete intervention programs. Results from this research will help enhance future online mindfulness interventions.

Resumen Introducción Derivado de la pandemia del COVID-19, la prevalencia de estrés, ansiedad, depresión y consumo de alcohol ha incrementado entre los estudiantes de medicina. La intervención por Mindfulness ha reportado disminuir estas psicopatologías y el consumo de alcohol; no obstante, la evidencia muestra resultados poco claros respecto a su eficacia. Objetivo Evaluar la eficacia de la intervención basada en Mindfulness online (IBM) sobre los niveles de sintomatología de estrés, ansiedad y depresión, así como en el consumo de alcohol y el estado de atención plena en estudiantes de medicina durante la pandemia por COVID-19. Método Se realizó una investigación cuasi-experimental en 237 estudiantes de medicina, de los cuales se obtuvieron datos sociodemográficos; además, se midieron los niveles de psicopatologías, consumo de alcohol, y el estado de atención plena pre y post intervención a través de los instrumentos DASS-21, AUDIT, y MASS. Se llevaron a cabo ocho sesiones de Mindfulness online, una vez por semana, de aproximadamente una hora cada una. Resultados La IBM no redujo los niveles de psicopatologías ni de consumo de alcohol ni mejoró el estado de atención plena. Los altos niveles de psicopatologías, la tasa de abandono y la falta de participación voluntaria, fueron los principales factores que limitan la eficacia del IBM online. Discusión y conclusión La IBM online no fue efectiva entre la población estudiada: se recomienda la generación de estrategias en las que los estudiantes se involucren y completen los programas de intervención, los resultados de esta investigación ayudarán a mejorar futuras intervenciones de mindfulness online.

The identification and evaluation of these biomarkers for health diagnosis provide gains for an area related to telemedicine, precision medicine. It was developed a mobile application called Neuropesquisa, which has features to find these biomarkers while users complete psychological scales for mental health. The aim was to correlate mindfulness, anxiety and reaction time, and track possible digital phenotypes of users. This was an observational study, with a cross-sectional, correlational, and remote design with 364 adults, through Neuropesquisa. There were positive correlations between mindfulness and reaction time, and negative correlations between anxiety and reaction time. It was concluded that Neuropesquisa was able to identify digital phenotypes among the considered constructs, of relevant importance for precision medicine and mental health.

Validación del instrumento Self-Compassion Scale para valoración de la autocompasión en estudiantes y médicos en Chile / Validation of the 12 items self-compassion scale in Chile

BACKGROUND: Self-compassion is understood as a mental framework when facing difficulties in life or personal insufficiency. It arises in response to the negative aspects of self-esteem. It is assessed using the 26 item and six factor Self-Compassion Scale (SCS) in the United States and Spain but not in Chile. AIM: To validate the 12-item version (SCS-12) of the self-compassion scale. MATERIAL AND METHODS: A back translation process of the original SCS-12 scale was carried out and then it was reviewed by 6 experts. The scale was applied to a sample of 359 medical students and 795 physicians. For internal validity, confirmatory factor analyses (CFA) were performed for one, two, three, and six factors. For external validity, bivariate correlations were made with variables about mental health, burnout, symptoms of depression and anxiety. Finally, a path analysis was carried out to study the relationship between the six factors and mental health. RESULTS: The CFA for the six-factor model presents the best fit for both groups of respondents (χ2 = 216.17, df = 80, p < .01; comparative fit index (CF)I = .96; Tucker-Lewis index (TL)I = .94; Root Mean Square Error of Approximation (RMSEA) = .05 [.04, .06]; Standarized Root Mean-Square(SRMR) = .04 and χ2 = 85.97, df = 39, p < .01; CFI = .97; TLI = .95; RMSEA = .06 [.04, .07]; SRMR = .04). The external validity was adequate. CONCLUSIONS: The 12-item version of the linguistically adapted Self-Compassion Scale instrument applied to medical students and physicians in Chile, had adequate internal validity and psychometric properties.

Mindfulness-Based Cognitive Therapy (MBCT) and Mindfulness-Based Stress Reduction (MBSR) in the treatment of Post-Traumatic Stress Disorder (PTSD): A literature review / Terapia Cognitiva Basada en Mindfulness y Reducción del Estrés Basada en Mindfulness en el tratamiento del Trastorno de Estrés Postraumático (TEPT): Una revisión de literatura

Abstract Background Previous reviews have concluded that whilst mindfulness-based interventions reduce PTSD symptoms through fear extinction and cognitive restructuring, further research is needed. Objective The aim of this report is to systematically review existing literature about the association between standardized mindfulness-based interventions and PTSD with the aim of identifying implications for practice and recommendations for future research. Method The CINAHL Complete, PsycINFO, Medline, and PsycArticles databases were searched, looking for full-text articles from 2018 up to march 2022. Results There was a significant improvement in PTSD symptoms in MBCT participants, even if some experienced a high increase at baseline. MBSR participants with moderate to severe trauma symptoms showed a greater reduction in symptoms whereas mild trauma symptoms at baseline showed slightly higher symptomatology at the end of treatment. Discussion and conclusion From the results, MBCT, MBSR, and their variations seem to tackle different domains of the diagnosis. Whilst MBSR is associated with improvements in terms of attentional difficulties, MBCT facilitates the connection between dysfunctional cognitive concepts and avoidant behaviours that maintain the symptomatology. Nevertheless, the active components of MBCT or MBSR that have an impact on symptom reduction are undetermined. Future studies will be enhanced by monitoring the change in underlying mechanisms attached to the practice of mindfulness through outcome measurements, among other considerations.

Resumen Antecedentes Las revisiones anteriores han concluido que las intervenciones basadas en la atención plena reducen los síntomas del TEPT a través de la extinción del miedo y la reestructuración cognitiva, aunque se requiere mayor evidencia. Objetivo Revisar sistemáticamente la literatura existente sobre la asociación entre las intervenciones estandarizadas basadas en mindfulness y el TEPT con el objetivo de identificar implicaciones para la práctica y recomendaciones para futuras investigaciones. Método Se realizaron búsquedas en las bases de datos CINAHL Complete, PsycINFO, Medline y PsycArticles de textos completos desde 2018 hasta marzo de 2022. Resultados Hubo una mejora significativa en los síntomas de TEPT en los participantes de MBCT, incluso si algunos experimentaron un gran aumento al inicio. Los participantes de MBSR con síntomas de trauma moderado a severo mostraron una mayor reducción de los síntomas, mientras que los síntomas de trauma leve al inicio mostraron una sintomatología ligeramente más alta al final del tratamiento. Discusión y conclusión A partir de los resultados, MBCT, MBSR y sus variaciones parecen abordar diferentes dominios del diagnóstico. Mientras que MBSR se asocia con mejoras en términos de dificultades atencionales, MBCT facilita la conexión entre conceptos cognitivos disfuncionales y conductas de evitación que mantienen la sintomatología. Sin embargo, los componentes activos de MBCT o MBSR que tienen un impacto en la reducción de los síntomas son indeterminados. Los estudios futuros se mejorarán al monitorear el cambio en los mecanismos subyacentes asociados a la práctica de la atención plena a través de mediciones de resultados, entre otras consideraciones.

The state mindfulness scale for physical activity: further psychometrics properties / Escala de estado de mindfulness para atividade física: novas propriedades psicométricas / Escala de mindfulness en la actividad física: nuevas propiedades psicométricas

Mindfulness has been defined as attention and awareness to the present with an attitude of openness, non-judgment, and acceptance. It is suggested that mindfulness can positively influence experiences in sports and physical activity, increasing adherence to these activities. This study aimed to examine new psychometric properties of the State Mindfulness Scale for Physical Activity (SMS-PA) using classical and modern testing theories among Brazilian sport and exercise practitioners. Two studies were conducted. In the first, with 617 Brazilian sports practitioners, confirmatory factor analysis supported the bifactor structure of the SMS-PA composed of two specific (mental and body mindfulness) and one general factor (state mindfulness), which did not vary among genders. The Rasch Rating Scale Model (RSM) supported essential one-dimensionality indicated by the general factor with good item fit statistics (infit/outfit 0.62-1.27). The model presented a good level of Rasch reliability (0.85), and the items difficulty estimation provided an understanding of the continuum represented by their content. In the second study, with 249 Brazilian exercise practitioners, the structural equation modeling showed that Body Mindfulness was associated with positive outcomes (positive affect and satisfaction with practice). The mediation analysis showed that people with higher levels of Body mindfulness tend to experience greater levels of Positive Affect and, consequently, greater Satisfaction with exercises. The results suggest that the Brazilian version of the SMS-PA is an appropriate measure of the state of mindfulness.(AU)

Mindfulness pode ser definido como atenção e consciência no momento presente com uma atitude de abertura, não julgamento e aceitação. A literatura sugere que o mindfulness pode influenciar positivamente experiências no esporte e atividade física e pode exercer um papel na adesão a essas atividades. Este estudo teve como objetivo investigar novas propriedades psicométricas da State Mindulness Sacale for Physical Activity (SMS-PA) utilizando as teorias clássicas e modernas dos testes em praticantes de exercício físico e esporte brasileiros. Dois estudos foram conduzidos. No primeiro, com 617 brasileiros praticantes de esporte, a Análise Fatorial Confirmatória (AFC) demonstrou adequação à estrutura bifatorial da SMS-PA composta por dois fatores específicos (mindfulness mental e físico) e um fator geral (estado de mindfulness), que apresentou invariância entre sexos. A Rasch Rating Scale Model (RSM) corroborou a unidimensionalidade essencial indicada pelo fator geral com bons índices de ajustes (infit/outfit 0.62 -1.27). O modelo apresentou bom nível de precisão Rasch (.85), e a estimação de dificuldade dos itens possibilitou compreensão do continuum representado pelo conteúdo dos itens. No segundo estudo, com 249 brasileiros praticantes de esporte, a Modelagem de Equações Estruturais demonstrou que o mindfulness físico esteve associado a afetos positivos e satisfação com a prática. A análise de mediação mostrou que pessoas com níveis altos de mindfulness físico tendem a apresentar níveis mais elevados de afeto positivo e, consequentemente, níveis mais elevados de satisfação com a prática. Os resultados sugerem que a versão brasileira do SMS-PA é uma medida apropriada do estado de mindfulness para atividades físicas.(AU)

La atención plena puede definirse como la atención y la conciencia en el momento presente con una actitud de apertura, no juicio y aceptación. La literatura sugiere que el mindfulness puede influir positivamente en las experiencias en el deporte y en la actividad física, además de desempeñar un papel en la adherencia a estas actividades. Este estudio tuvo como objetivo investigar nuevas propiedades psicométricas de la State Mindfulness Scale for Physical Activity (SMS-PA) utilizando las teorías clásicas y modernas de las pruebas en practicantes de ejercicio físico y de deporte en Brasil. Para ello, se realizaron dos estudios. En el primer, participaron 617 practicantes de deporte brasileños, y el análisis factorial confirmatorio (AFC) demostró adecuación en la estructura bifactorial de la SMS-PA, compuesta por dos factores específicos (mindfulness mental y físico) y un factor general (estado de mindfulness), que mostró invarianza entre sexos. El Rasch Rating Scale Model (RSM) corroboró la unidimensionalidad esencial indicada por el factor general con buenos índices de ajuste (infit/outfit 0,62-1,27). El modelo mostró un buen nivel de precisión de Rasch (.85), y la estimación de la dificultad de los ítems permitió comprender el continuo representado por el contenido de estos. En el segundo estudio, con 249 practicantes de deporte, el modelo de ecuaciones estructurales mostró que el mindfulness físico estaba asociado a resultados positivos (afecto positivo y satisfacción con la práctica). El análisis de mediación reveló que las personas con altos niveles de mindfulness físico tendían a tener mayores niveles de afecto positivo y, en consecuencia, mayores niveles de satisfacción con la práctica. Los resultados sugieren que la versión brasileña de la SMS-PA es una medida adecuada de mindfulness.(AU)

Impacto de um Programa de Redução do Estresse, Meditação e Mindfulness em Pacientes com Insuficiência Cardíaca Crônica: Um Ensaio Clínico Randomizado / Impact of a Stress Reduction, Meditation, and Mindfulness Program in Patients with Chronic Heart Failure: A Randomized Controlled Trial

Resumo Fundamento A Insuficiência Cardíaca é um importante problema de saúde pública, que leva à alta carga de sintomas físicos e psicológicos, apesar da terapia otimizada. Objetivo Avaliar primariamente o impacto de um Programa de Redução de Estresse, Meditação e Atenção plena na redução do estresse de pacientes com Insuficiência Cardíaca. Métodos Ensaio clínico randomizado e controlado que avaliou o impacto de um programa de redução de estresse comparado ao atendimento multidisciplinar convencional, em dois centros especializados no Brasil. O período de coleta de dados ocorreu entre abril e outubro de 2019. Um total de 38 pacientes foram alocados nos grupos de intervenção ou controle. A intervenção aconteceu ao longo de 8 semanas. O protocolo consistiu na avaliação das escalas de estresse percebido, depressão, qualidade de vida, ansiedade, atenção plena, qualidade do sono, teste de 6 minutos de caminhada e biomarcadores por um grupo cego, considerando um p-valor <0,05 como estatisticamente significativo. Resultados A intervenção resultou em redução significativa no estresse percebido de 22,8 ± 4,3 para 14,3 ± 3,8 pontos na escala de estresse percebido no grupo de intervenção vs. 23,9 ± 4,3 para 25,8 ± 5,4 no grupo controle (p-valor<0,001). Foi observada melhora significativa na qualidade de vida (p-valor=0,013), atenção plena (p-valor=0,041), qualidade do sono (p-valor<0,001) e no teste de 6 minutos de caminhada (p-valor=0,004) no grupo sob intervenção comparado com o controle. Conclusão O Programa de Redução de Estresse, Meditação e Atenção plena reduziu efetivamente o estresse percebido e melhorou desfechos clínicos em pacientes com Insuficiência Cardíaca.

Abstract Background Heart Failure is a significant public health problem leading to a high burden of physical and psychological symptoms despite optimized therapy. Objective To evaluate primarily the impact of a Stress Reduction, Meditation, and Mindfulness Program on stress reduction of patients with Heart Failure. Methods A randomized and controlled clinical trial assessed the effect of a stress reduction program compared to conventional multidisciplinary care in two specialized centers in Brazil. The data collection period took place between April and October 2019. Thirty-eight patients were included and allocated to the intervention or control groups. The intervention took place over 8 weeks. The protocol assessed the scales of perceived stress, depression, quality of life, anxiety, mindfulness, quality of sleep, a 6-minute walk test, and biomarkers analyzed by a blinded team, considering a p-value <0.05 statistically significant. Results The intervention resulted in a significant reduction in perceived stress from 22.8 ± 4.3 to 14.3 ± 3.8 points in the perceived stress scale-14 items in the intervention group vs. 23.9 ± 4.3 to 25.8 ± 5.4 in the control group (p-value<0.001). A significant improvement in quality of life (p-value=0.013), mindfulness (p-value=0.041), quality of sleep (p-value<0.001), and the 6-minute walk test (p-value=0.004) was also observed in the group under intervention in comparison with the control. Conclusion The Stress Reduction, Meditation, and Mindfulness Program effectively reduced perceived stress and improved clinical outcomes in patients with chronic Heart Failure.

Os impactos de técnicas não farmacológicas na impulsividade / The impacts of non-pharmacological techniques on impulsivity

A impulsividade é um fenômeno multifacetado e é caracterizada por diferentes padrões cognitivos e comportamentais que podem levar a consequências disfuncionais imediatas e em médio/longo prazo. O tratamento da impulsividade tem sido um grande desafio na área da saúde mental, pois não há muitas ferramentas bem descritas e cientificamente validadas que sejam eficazes para a melhora do bem-estar geral desses indivíduos. Dentre as abordagens gerais que podem ser utilizadas para isso, destacam-se as intervenções farmacológicas, atividades físicas e abordagens psicoterápicas como a terapia cognitivo-comportamental (TCC), o treinamento de habilidades sociais e emocionais e a terapia de controle de impulsos. Neste estudo, iremos analisar outras três técnicas não farmacológicas promissoras para serem utilizadas no controle de impulso que são as técnicas de Yoga, Mindfulness e Neuromodulação não invasiva. Para isso, fizemos três revisões sistemáticas conduzidas em acordo com os critérios do PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Os protocolos de revisão foram registrados no Registro Prospectivo Internacional de Revisões Sistemáticas (PROSPERO). Para escolha dos descritores que seriam utilizados na busca foi utilizado o Medical Subject Headings (MeSH). A pesquisa pelos artigos foi feita nas bases de dados da PubMed, Scopus, Science Direct e Embase. Só foram incluídos artigos em inglês e não houve delimitação de período de publicação dos artigos incluídos. Os artigos incluídos nesta revisão sistemática foram selecionados de forma independente por dois revisores distintos. Eles realizaram a seleção em duas etapas, sendo a primeira baseada na leitura dos títulos e resumos e a segunda com a leitura completa do texto e caso houvesse divergência na seleção dos artigos, um terceiro revisor foi acionado. A qualidade dos estudos incluídos nestas revisões sistemáticas foi avaliada utilizando a ferramenta Cochrane Risk of Bias tool. Ao final da seleção dos artigos, 6 artigos foram analisados no estudo sobre yoga, 18 no de Mindfulness e 18 no de Neuromodulação não invasiva (9 artigos sobre Estimulação Transcraniana por Corrente Contínua (ETCC) e 9 sobre Estimulação Magnética Transcraniana (EMT)) e foi realizada metanálise de seus dados. Com base nos resultados obtidos, as técnicas de Yoga e Mindfulness surgem como promissoras no tratamento da impulsividade, demonstrando efetividade em diversos testes psicométricos e escalas. Essas abordagens terapêuticas são de fácil implantação, escaláveis e apresentam baixo custo, o que as torna viáveis tanto para o contexto clínico quanto para a saúde pública. Por outro lado, os estudos sobre ETCC e EMT ainda carecem de evidências suficientes para embasar sua implementação no tratamento da impulsividade. A falta de padronização nos estímulos utilizados e a diversidade nos desenhos de estudo dificultam a definição de protocolos efetivos. Portanto, futuras pesquisas serão necessárias para estabelecer parâmetros mais específicos e padrões de intervenção claros para essas técnicas de neuromodulação não invasiva no contexto da impulsividade.

Impulsivity is a multifaceted phenomenon characterized by different cognitive and behavioral patterns that can lead to immediate and medium-to-long-term dysfunctional consequences. The treatment of impulsivity has been a major challenge in the field of mental health, as there are not many well-described and scientifically validated tools that are effective in improving the overall well-being of these individuals. Among the general approaches that can be used for this purpose, pharmacological interventions, physical activities, and psychotherapeutic approaches such as cognitive-behavioral therapy (CBT), social and emotional skills training, and impulse control therapy stand out. In this study, we will analyze three other promising non-pharmacological techniques for impulse control, namely Yoga, Mindfulness, and non-invasive neuromodulation. To do so, we conducted three systematic reviews in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria. The review protocols were registered in the International Prospective Register of Systematic Reviews (PROSPERO). The Medical Subject Headings (MeSH) were used to select the descriptors for the search. The article search was conducted in the PubMed, Scopus, Science Direct, and Embase databases. Only articles in English were included, and there was no restriction on the publication period of the included articles. The articles included in this systematic review were independently selected by two different reviewers. They performed the selection in two stages, the first based on the reading of titles and abstracts, and the second with the full-text reading. In case of divergence in the article selection, a third reviewer was consulted. The quality of the studies included in these systematic reviews was assessed using the Cochrane Risk of Bias tool. At the end of the article selection process, 6 articles were analyzed in the Yoga study, 18 in the Mindfulness study, and 18 in the non-invasive neuromodulation study (9 articles on Transcranial Direct Current Stimulation (tDCS) and 9 on Transcranial Magnetic Stimulation (TMS)), and a meta-analysis of their data was performed. Based on the results obtained, Yoga and Mindfulness techniques emerge as promising in the treatment of impulsivity, demonstrating effectiveness in various psychometric tests and scales. These therapeutic approaches are easy to implement, scalable, and cost-effective, making them viable for both clinical and public health contexts. On the other hand, studies on tDCS and TMS still lack sufficient evidence to support their implementation in the treatment of impulsivity. The lack of standardization in the stimuli used and the diversity in study designs hinder the definition of effective protocols. Therefore, future research will be necessary to establish more specific parameters and clear intervention standards for these non-invasive neuromodulation techniques in the context of impulsivity

O impacto das intervenções de meditação breve e extremamente breve nas taxas de sucesso de Técnicas de Reprodução Assistida: um estudo controlado randomizado / The impact of brief and extremely brief meditation interventions on the success rates of Assisted Reproductive Techniques: a randomized controlled trial

Introdução: As taxas de sucesso da gravidez com as técnicas de reprodução assistida (ART) têm melhorado constantemente. O efeito das intervenções não farmacológicas, como a meditação, como terapias adjuvantes, nos resultados dos ciclos de ART tem sido pesquisado com resultados promissores. No entanto, até onde sabemos, há muitas dúvidas sobre os efeitos os efeitos de meditação breve e extremamente breve nas taxas de sucesso em ART. Portanto, uma meditação extremamente breve guiada por facilitador e uma meditação breve em formato de áudio e autogerenciada foram estudadas. Objetivo: Investigar o efeito das intervenções da meditação breve (IMB) e extremamente breve (IMEB) na taxa de gravidez em mulheres submetidas à Tecnologia de Reprodução Assistida (TRA). Método: Trata-se de um estudo prospectivo, randomizado, controlado com três braços. As intervenções foram realizadas no período de espera entre a transferência de embriões e o teste de gravidez ß-hCG. O tamanho da amostra foi calculado pelo qui-quadrado de Pearson com base no poder de 80%, tamanho do efeito de 0,4 e nível de confiança de 95%. As variáveis relacionadas ao sucesso da TRA foram incluídas na análise: idade em anos, número de embriões/blastocistos transferidos, número de embriões/blastocistos com qualidade excelente ou muito boa, número de ciclos de fertilização in vitro, faixa etária e se foi transferido embrião ou blastocisto. O teste qui-quadrado (χ2) e ANOVA compararam os valores das variáveis entre os grupos de intervenções e controle. A Análise de Regressão Logística Univariada avaliou se cada variável relacionada ao sucesso da TRA influenciou ou não a resposta da variável de desfecho "gravidez". Utilizou-se Análise de Regressão Logística Múltipla para avaliar a influência dessas variáveis em conjunto no desfecho da gravidez. Resultados: Foram incluídas 68 mulheres com idade de 37,5+4,3 anos (IMEB, n=24; IMB n=22 e GC, n=22). O teste qui-quadrado de Pearson e o teste t de Student para amostras independentes mostraram que não houve diferenças significativas (p<0,05) entre os grupos intervenção e grupo controle. Tanto a IMEB quanto a IMB não tiveram efeito significativo na taxa de gravidez em mulheres submetidas à ART. Conclusão: O uso da meditação breve ou extremamente breve não demonstrou diferenças significativas na taxa de gravidez entre os grupos intervenção e grupo controle, em mulheres sob tratamento com Técnicas de Reprodução Assistida. Os resultados dos efeitos da meditação na taxa de gravidez de mulheres em TRA são inconclusivos na literatura. Necessita-se de ensaios controlados randomizados com amostras maiores comparando ambas as intervenções de meditações breves e extremamente breves a um grupo controle para confirmar os achados deste estudo.

Introduction: Pregnancy success rates with assisted reproductive technology (ART) have steadily improved. The effect of non-pharmacological interventions such as meditation as adjunctive therapies on the outcomes of ART cycles has been researched with promising results. However, to the best of our knowledge, there is much doubt about the effects of brief and extremely brief meditation on ART success rates. Therefore, an extremely brief facilitatorguided meditation and an audio-guided, self-paced short meditation were studied. Objectives: To investigate the effect of extremely brief meditation (EBMI) or brief mindfulness interventions (Brief MI) on pregnancy rate in women undergoing Assisted Reproductive Technology (ART). Method: This is a prospective three arms randomized, controlled study. Interventions were performed in the waiting period between embryo transfer and the ß-hCG pregnancy test. The sample size was calculated using Pearson's chi-square based on a power of 80%, effect size of 0.4 and a confidence level of 95%. Variables related to the success of ART included in the analysis consisted of age in years, number of embryos/blastocysts transferred, number of embryos/blastocysts with excellent or very good quality, number of in vitro fertilization cycles, age range, and whether the embryo was transferred or blastocyst. Chi-square test (χ2) and ANOVA compared variable values between intervention and control groups. Univariate Logistic Regression Analysis evaluated whether each variable related to ART success influenced or not the response of the outcome variable "pregnancy". Multiple Logistic Regression Analysis assessed if these variables could influence jointly the outcome of pregnancy. Results: A total of 68 women aged 37.5+4.3y were included (EBMI, n=24; Brief MI, n=22 and CG, n=22) were. Pearson's Chi-square test and Student's t test for independent samples showed that there were no significant differences (p<0.05) between the intervention groups and control group. Both EBMI and BMI had no significant effect on pregnancy rate in women undergoing ART. Conclusion: The use of brief or extremely brief meditation did not demonstrate significant differences in the pregnancy rate between the intervention and control groups in women undergoing treatment with Assisted Reproductive Techniques. The results of the effects of meditation on the pregnancy rate of women on ART are inconclusive in the literature. Larger sample randomized controlled trials comparing both brief and extremely brief meditation interventions to a control group are needed to confirm the findings of this study.

The effects of short video app-guided loving-kindness meditation on college students' mindfulness, self-compassion, positive psychological capital, and suicide ideation

Abstract Objective The study investigated the effects of a short video app guided loving-kindness meditation (LKM) on college students' mindfulness, self-compassion, positive psychological capital, and suicide ideation. The purpose of the study is to investigate the intervention effect of LKM training on suicidal ideation among college students with the help of the short video application and to provide an empirical basis for the exploration of early suicide intervention strategies for college students. Methods We recruited 80 college students from a university in China. The final 74 eligible participants were divided into two groups: app use group (n = 37) and the control group (n = 37). The app group accepted an 8-week app use interference, while the control group underwent no interference. We measured four major variable factors (mindfulness, self-compassion, positive psychological capital, and suicide ideation) before and after the app use intervention. Results In the app group, self-compassion and positive psychological capital were significantly higher, and suicide ideation was significantly lower than the control group. In the control group, there were no noticeable differences in any of the four variables between the pre-test and post-test. Conclusions Our findings demonstrate that the short video app guided LKM may help to improve self-compassion, and positive psychological capital, and reduce suicide ideation. The finding of the short video app-guided LKM's effect extends our understanding of the integrative effects of positive psychology and digital media on the reduction of suicide ideation.

Meditação para estresse e ansiedade em universitários: um ensaio clínico randomizado / Meditation for stress and anxiety relief in undergraduate students: a randomized clinical trial

Resumo: Introdução: O estresse é um estado no qual ocorrem ameaças à homeostase do organismo, com respostas adaptativas fisiológicas e comportamentais. A ansiedade é uma sensação desagradável advinda da percepção de uma ameaça potencial futura. Quando prolongados, ambos levam a repercussões metabólicas, cardiovasculares, imunológicas e neuropsiquiátricas. Os estudantes universitários são mais susceptíveis a sintomas de estresse e ansiedade do que a população em geral. A técnica de mindfulness permite que os seus praticantes se tornem mais conscientes de suas emoções, passando a responder de forma habilidosa ao estresse e à ansiedade Objetivo: Este estudo teve como objetivo avaliar a eficácia de um programa de mindfulness na redução de sintomas de estresse e ansiedade em estudantes de Medicina e Odontologia. Método: Trata-se de um ensaio clínico, randomizado, simples-cego. Acadêmicos regularmente matriculados do primeiro ao oitavo período desses cursos de uma instituição de ensino superior responderam ao Inventário de Sintomas de Stress para Adultos de Lipp (ISSL) (n = 418) e ao Inventário de Ansiedade Traço-Estado (IDATE) (n = 369). Os participantes que apresentaram sintomas de estresse e/ou ansiedade e aceitaram participar da intervenção (n = 59) foram randomizados em grupos mindfulness (programa modificado de duas semanas) e de controle. Ao final da intervenção, o ISSL e o IDATE foram reaplicados. Resultado: As prevalências globais de estresse e ansiedade foram de 67% (n = 280) e 76,4% (n = 282), respectivamente. Ao final da segunda semana, a redução dos sintomas de estresse e ansiedade foi de 30,8% e 22,2%, respectivamente. Não houve diferença estatisticamente significativa entre os grupos mindfulness e de controle (p > 0,05). Conclusão: Percebe-se uma alta prevalência de sintomas de estresse e ansiedade na população estudada. Um programa de mindfulness em formato reduzido não foi capaz de diminuir significativamente os sintomas de estresse e ansiedade em comparação ao grupo de controle, em acadêmicos de Medicina e Odontologia dessa instituição.

Abstract: Introduction: Stress is a state in which the body homeostasis is threatened, leading to adaptive, physiological and behavioral responses. Anxiety is an unpleasant feeling that occurs whenever a future potential threat is perceived. Whenever these states are prolonged, both lead to metabolic, cardiovascular, neuropsychiatric and immunological consequences. University students are more susceptible to stress and anxiety symptoms than the general population. Mindfulness is a technique that allows its practitioners to become more aware of their emotions, dealing with stress in a more skilled way. Objective: To; evaluate the efficacy of a modified mindfulness program in reducing stress and anxiety symptoms in medicine and dentistry undergraduate students. Methods: This was a single blinded, randomized, clinical trial. Students from the aforementioned courses enrolled in the 1st to the 8th semesters of a higher education institution, answered Lipp's Inventory of Stress symptoms for Adults (ISSL) (n=418) and the State-Trace Anxiety Inventory (STAI) (n=369). Those who showed a positive score for symptoms of stress and/or anxiety and accepted to take part in the intervention (n=59), were randomized into one of the two groups - mindfulness (a 2-week modified program), or control. After the intervention, the students were asked to answer the STAI and ISSL tools once again. Results: The global prevalence of stress and anxiety symptoms were 67% (n=280) and 76.4% (n=282), respectively. At the end of the second week, symptoms of stress and anxiety decreased 30.8% and 22.2%, respectively. There were no statistically significant differences between the mindfulness and control groups (p>0.05). Conclusion: Symptoms of stress and anxiety are highly prevalent among the studied population. Among medicine and dentistry undergraduate students in this higher education institution, a shortened mindfulness program was unable to reduce symptoms of stress and anxiety in a statistically significant way when compared to a control group.

The Effect of Mindfulness-Based Stress Reduction Counseling on Blood Glucose and Perceived Stress in Women with Gestational Diabetes / O efeito do aconselhamento para redução do estresse baseado na atenção plena sobre a glicose no sangue e o estresse percebido em mulheres com diabetes gestacional

Abstract Objective Gestational diabetes can cause maternal and neonatal morbidity. Psychological factors, especially stress, play a meaningful role in diabetes management. Therefore, the present study aimed to investigate the effect of Mindfulness-Based Stress Reduction counseling on blood sugar and perceived stress in women with gestational diabetes. Methods The present quasi-experimental interventional study was performed on 78 women with gestational diabetes. In the intervention group, a Mindfulness-Based Stress Reduction counseling program was conducted by the researcher in 8 sessions of 90 minutes twice a week. The Cohen stress questionnaire was filled in both groups. Also, fasting blood sugar and 2-hour blood sugar levels were measured in both groups. Statistical analysis was performed using the independent T-Test, the paired T-Test, the Mann-Whitney and Wilcoxon Tests using IBM SPSS Statistics for Windows version 20 version (IBM Corp., Armonk, NY, USA). Results The mean age of pregnant women in the intervention group was 28.84 ± 6.20 years old and 29.03 ± 5.42 years old in the control group. There was a significant mean difference between the fasting blood sugar score (p= 0.02; - 6.01; and - 11.46) and the 2-hour fasting blood sugar score (p< 0.001;12.35; and - 5.3) and the perceived stress score (p< 0.001; 35.57; and - 49.19) existed between the intervention and control groups after the intervention. Conclusion The results of the present study showed that mindfulness-based stress reduction counseling is effective in reducing blood sugar levels and reducing perceived stress in women with gestational diabetes treated with diet.

A Randomized Controlled Trial of Mindfulness in Recovery from Colorectal Cancer / 中国结合医学杂志

OBJECTIVE@#This study examined whether a 4-week group-based mindfulness intervention would be superior in reducing psychological distress in colorectal cancer (CRC) patients compared to a psychoeducation and cognitive behavioural skills learning support active control group.@*METHODS@#Patients with CRC were randomized via Computerised Permuted Block Randomisation to mindfulness or active control groups (2-h weekly sessions over 4 weeks). Outcomes were measured pre-intervention, and 8 weeks and 6 months post-baseline. The primary outcome was psychological distress measured by the Hospital Anxiety and Depression Scale. Secondary outcomes were generic quality of life (QoL), disease specific QoL, mindfulness, and intervention credibility and acceptability.@*RESULTS@#Sixty-eight participants were randomized to mindfulness (n=35) or active control group (n=33). Uptake of potentially eligible patients consenting was low (28.0%) and the dropout rate was 33.8%. Depression scores were reduced in both groups at week 8 (P=0.020). Control participants had greater improvement in generic mental QoL scores at week 8 than mindfulness (P=0.023). In disease specific QoL, there was reduction in impotence symptom in the mindfulness group (P=0.022) and reduction in faecal incontinence in the control group (P=0.019). The embarrassment symptom had a significantly lower increase in the mindfulness group at week 8 compared to the control group (P=0.009). Both groups rated the treatments as credible and acceptable.@*CONCLUSIONS@#Mindfulness was not superior to the active control group in terms of alleviating psychological distress but both treatments were associated with some improvements in depression. There was low uptake of both interventions. (Trial registration number: ACTRN12616001033437).

Benefits of Mindfulness Training on the Mental Health of Women During Pregnancy and Early Motherhood: A Randomized Controlled Trial / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to evaluate the effects of a mindfulness-based psychosomatic intervention on depression, anxiety, fear of childbirth (FOC), and life satisfaction of pregnant women in China.@*METHODS@#Women experiencing first-time pregnancy ( n = 104) were randomly allocated to the intervention group or a parallel active control group. We collected data at baseline (T0), post-intervention (T1), 3 days after delivery (T2), and 42 days after delivery (T3). The participants completed questionnaires for the assessment of the levels of depression, anxiety, FOC, life satisfaction, and mindfulness. Differences between the two groups and changes within the same group were analyzed at four time points using repeated-measures analysis of variance.@*RESULTS@#Compared with the active control group, the intervention group reported lower depression levels at T2 ( P = 0.038) and T3 ( P = 0.013); reduced anxiety at T1 ( P = 0.001) and T2 ( P = 0.003); reduced FOC at T1 ( P < 0.001) and T2 ( P = 0.04); increased life satisfaction at T1 ( P < 0.001) and T3 ( P = 0.015); and increased mindfulness at T1 ( P = 0.01) and T2 ( P = 0.006).@*CONCLUSION@#The mindfulness-based psychosomatic intervention effectively increased life satisfaction and reduced perinatal depression, anxiety, and FOC.

Behavioral inhibition system and social anxiety among college students: multiple mediating effect of mindfulness and negative cognitive bias / 中华行为医学与脑科学杂志

Objective:To explore the role of mindfulness and negative cognitive bias between behavioral inhibition system and social anxiety among college students.Methods:From October 12th to November 8th of 2012, a total of 747 college students from a university in Tianjin were sampled and assessed using the behavioral inhibition system scale (BIS), the mindful attention awareness scale (MAAS), the negative cognitive processing bias questionnaire (NCPBQ), and the social avoidance and distress scale (SAD). Descriptive statistics, correlation analysis, and tests for mediating effects were performed by SPSS 20.0 and Mplus 8.0.Results:The scores of behavioral inhibition system, social anxiety, mindfulness and negative cognitive bias were (15.3±2.4), (12.7±7.2), (3.4±0.8) and (45.6±11.5), respectively. The scores of BIS, NCPBQ, and SAD were positively correlated with each other ( r=0.27-0.49, all P<0.001). The scores of MAAS were negatively correlated with the scores of BIS, NCBPQ, and SAD ( r=-0.33--0.28, all P<0.001). The behavioral inhibition system exerted its influence on social anxiety through three pathways. The mediating effect size of mindfulness was 0.04, accounting for 16.0% of the total effect. The mediating effect size of negative cognitive bias was 0.17, accounting for 68.0% of the total effect. And the chain mediating effect size of mindfulness and negative cognitive bias was 0.04, accounting for 16.0% of the total effect. Conclusion:The effects of behavioral inhibition system on social anxiety in college students are individually mediated by mindfulness and negative cognitive biases, as well as their chain mediating effects.

The chain mediating effect of mindfulness and perceived stress between childhood trauma and psychotic-like experiences among college freshmen / 中华行为医学与脑科学杂志

Objective:To explore the mediating effects of mindfulness and perceived stress between childhood trauma and psychotic-like experiences.Methods:In October 2021, 602 freshmen from a university in Guangdong Province were tested by childhood trauma questionnaire(CTQ), mindful attention awareness scale(MAAS), perceived stress scale(PSS), and community assessment of psychic experiences(CAPE). SPSS 21.0 and Mplus 8.3 were used for data analysis. Mann-Whitney U test was used to compare the differences between groups, and Spearman correlation analysis was used to investigate the correlation among childhood trauma, mindfulness, perceived stress and psychotic-like experiences. Bias-corrected nonparametric percentile Bootstrap method was used to examine the mediating roles of mindfulness and perceived stress between childhood trauma and psychotic-like experiences. Results:(1) In the past one month, 59.5% of the freshmen had psychotic-like experiences, and 8.5% of them experienced the distress. (2)Childhood trauma was positively correlated with perceived stress( r=0.29, P<0.01), frequency ( r=0.14, P<0.01)and distress( r=0.17, P<0.01) of psychotic-like experiences, and was negatively correlated with mindfulness( r=-0.28, P<0.01). (2)Mindfulness and perceived stress played individual mediating effects and chain mediating effect between childhood trauma and frequency of psychotic-like experiences, with effect size of 0.08, 0.04, 0.03, accounting for 53.33%, 26.67%, 20.00% of the total indirect effect(effect size=0.15), respectively. Mindfulness and perceived stress played individual mediating effects and chain mediating effect between childhood trauma and distress of psychotic-like experiences, with effect size of 0.07, 0.04, 0.03, accounting for 50.00%, 28.57%, 21.43% of the total indirect effect(effect size=0.14), respectively. Conclusion:Childhood trauma can affect psychotic-like experiences and distress through the indirect effects of mindfulness and perceived stress, or through the chain mediating effect of mindfulness-perceived stress.

Qualitative research on the adherence of mindfulness practice in psychological counseling outpatients / 上海预防医学

ObjectiveTo explore the barriers and facilitators of the adherence of formal practice after mindfulness-based cognitive therapy （MBCT） in psychological counseling outpatients. MethodsOne-on-one interview was conducted in 15 psychological counseling outpatients who attended MBCT at Shanghai Mental Health Center and had been out of treatment 5 months or more. Data was analyzed using thematic analysis. ResultsPoor mood， weak willpower， limited time and space， lack of companionship and supervision， and discomfort with the recording were the five factors that prevented the patients from sticking to their practice. Personality trait， trust， benefit， need for self-care， time/space arrangement， fellow practitioners， therapists， and ease and convenience of practice were the eight factors that promoted the patients to practice. ConclusionThe COM-B model helps therapists and individuals with practice needs to understand the mechanism of formal practice facilitators at a holistic level. Therapists and individuals with practice needs should be concerned about possible barriers on the adherence of formal practice.
