Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part II: cognitive-behavioral therapy

Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD.

Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part I: pharmacological treatment

Objectives: To summarize evidence-based pharmacological treatments and provide guidance on clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The American Psychiatric Association (APA) guidelines for the treatment of OCD (2013) were updated with a systematic review assessing the efficacy of pharmacological treatments for adult OCD, comprising monotherapy with selective serotonin reuptake inhibitors (SSRIs), clomipramine, serotonin and norepinephrine reuptake inhibitors (SNRIs), and augmentation strategies with clomipramine, antipsychotics, and glutamate-modulating agents. We searched for the literature published from 2013-2020 in five databases, considering the design of the study, primary outcome measures, types of publication, and language. Selected articles had their quality assessed with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association (ACC/AHA). Results: We examined 57 new studies to update the 2013 APA guidelines. High-quality evidence supports SSRIs for first-line pharmacological treatment of OCD. Moreover, augmentation of SSRIs with antipsychotics (risperidone, aripiprazole) is the most evidence-based pharmacological intervention for SSRI-resistant OCD. Conclusion: SSRIs, in the highest recommended or tolerable doses for 8-12 weeks, remain the first-line treatment for adult OCD. Optimal augmentation strategies for SSRI-resistant OCD include low doses of risperidone or aripiprazole. Pharmacological treatments considered ineffective or potentially harmful, such as monotherapy with antipsychotics or augmentation with ketamine, lamotrigine, or N-acetylcysteine, have also been detailed.

Psychopathological intersection between obsessive-compulsive disorder and post-traumatic stress disorder: scoping review of similarities and differences

Abstract Introduction Although post-traumatic stress disorder and obsessive-compulsive disorder have distinct diagnostic criteria, some psychopathological phenomena seem to be shared, which may lead to misdiagnosis and erroneous treatment decisions. This scoping review explores the psychopathological similarities and differences between these two disorders. Method The review complies with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and included articles published in Portuguese, English, or Spanish in the last 50 years indexed in the PubMed database. Case-reports were excluded. Results Fifty-three studies with different designs were included (30 [56.5%] were cross-sectional studies; eight [15.1%] were case-control studies; one [1.9%] was a cohort study; three [5.7%] were clinical trials; nine [17%] were reviews/systematic reviews; and two [3.8%] were meta-analyses). The main psychopathological aspects described by the studies included were flashbacks x obsessions; avoidant behavior (AB); depressive, anxious, and somatic symptoms; sexuality, sleep, and appetite; psychiatric comorbidities; and suicidality. The intersection between clinical features seems to occur in the extrinsic psychopathological dimension. Conclusion The disorders' core psychopathological symptoms (intrinsic characteristics) are distinctly different, since flashbacks and obsessions are consequences of different predominant defective mental functions: the former derives from defective memory, the latter from defective thought. Along the same lines, the ABs observed in the two disorders are products of different purposes and inner necessities.

Efficacy of group cognitive-behavioral therapy in adolescents with obsessive compulsive disorder: a systematic review and meta-analysis

Objective: To evaluate the effectiveness of group cognitive-behavioral therapy (GCBT) for the treatment of adolescents with obsessive compulsive disorder (OCD). Methods: This review was registered in PROSPERO under number CRD42020158475. Five databases (PubMed, Virtual Health Library, Web of Science, Scopus, and PsycINFO) were searched. After applying the inclusion and exclusion criteria, 13 studies were analyzed in the qualitative synthesis (i.e., systematic review) and eight in the quantitative synthesis (i.e., meta-analysis). For the latter, fixed-effect modeling was used to assess the primary outcome (i.e., OCD symptoms). Results: The main findings suggest that GCBT is effective in reducing the symptoms of OCD in adolescents (d = -1.32). However, these results must be interpreted with caution, since all of the included studies showed some bias in their design. Conclusions: GCBT is effective in reducing OCD symptoms in adolescents.

Factor structure of the Dimensional Yale-Brown Obsessive-Compulsive Scale in a large sample of adults with obsessive-compulsive disorder

Objectives: Although the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a widely used instrument for assessing different obsessive-compulsive symptom dimensions, its factor structure has never been studied in a Brazilian population. Thus, we aimed to assess the goodness-of-fit indexes and factor loadings of two higher-order models of the DY-BOCS using confirmatory factor analysis (CFA) in a large obsessive-compulsive disorder (OCD) sample. Methods: We tested two CFA models in a sample of 955 adults with OCD who had been assessed with the DY-BOCS in a cross-sectional multi-site study. The first model encompassed the symptom checklist (present or absent), whereas the second focused on items related to severity scores. Results: Both models presented adequate goodness-of-fit indexes. The comparative fit index, Tucker-Lewis index, and omega were > 0.9, while the root mean square error of approximation was ≤ 0.06 for both models. Factor loadings for each item of each dimension are presented and discussed. Conclusion: Higher-order factor models showed adequate goodness-of-fit indexes, indicating that they appropriately measured OCD dimensions in this Brazilian population.

Appraising the effectiveness of electrical and magnetic brain stimulation techniques in acute major depressive episodes: an umbrella review of meta-analyses of randomized controlled trials

Electrical and magnetic brain stimulation techniques present distinct mechanisms and efficacy in the acute treatment of depression. This was an umbrella review of meta-analyses of randomized controlled trials of brain stimulation techniques for managing acute major depressive episodes. A systematic review was performed in the PubMed/MEDLINE databases from inception until March 2020. We included the English language meta-analysis with the most randomized controlled trials on the effects of any brain stimulation technique vs. control in adults with an acute depressive episode. Continuous and dichotomous outcomes were assessed. A Measurement Tool to Assess Systematic Reviews-2 was applied and the credibility of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation framework. Seven meta-analyses were included (5,615 patients), providing evidence for different modalities of brain stimulation techniques. Three meta-analyses were evaluated as having high methodological quality, three as moderate, and one as low. The highest quality of evidence was found for high frequency-repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation, and bilateral rTMS. There is strong clinical research evidence to guide future clinical use of some techniques. Our results confirm the heterogeneity of the effects across these techniques, indicating that different mechanisms of action lead to different efficacy profiles.

Detect-S: an mHealth application to assist health professionals to identify suicide risk in hospitalized patients

Abstract Introduction Suicide is a serious public health problem that affects the whole world. This study describes development of the prototype for an mHealth application (app) intended to assist healthcare professionals to identify suicide risk in hospitalized patients and reports on testing of the app by some of these professionals, conducted to confirm its functionality. Method This is applied exploratory research into use of Information Technology within the healthcare field, based on application prototyping for mobile devices. The research was conducted at the Universidade Federal de Ciências da Saúde de Porto Alegre (UFCSPA) from 2017 to 2019. Six healthcare professionals, one data scientist, and three undergraduate students in Biomedical Informatics took part in the study. All research participants signed the free and informed consent form. Results The main findings show that the development team created a prototype named Detect-S, which became a cross-platform application (iOS and Android) offering 16 functions. Conclusion It can be concluded that Detect-S has the potential to be a positive technological instrument that can be tested in a hospital setting to assist healthcare professionals to identify and manage patients with at risk of suicide.

Instruments to assess suicide risk: a systematic review

Abstract Introduction Suicide is an issue of great severity in public health worldwide. This study aimed to investigate which instruments are most frequently used by healthcare professionals to assess suicide risk and how accessible such instruments are, as well as to determine the scope of suicide phenomena. Method A systematic review was performed using the following Boolean searches: "scale AND suicide," "evaluation AND suicide," "questionnaire AND suicide." The articles retrieved were read and selected by two independent researchers - any discrepancies were addressed by a third researcher. Results From a total number of 206 articles, 20 instruments were identified as being currently used to assess suicide risk. The two most common were the Beck Scale for Suicide Ideation (BSI) and The Columbia - Suicide Severity Rating Scale (C-SSRS). Conclusion Even though the two scales (BSI and C-SSRS) are the most frequently mentioned and used by healthcare professionals to assess suicide risk, both instruments present breaches in their structure and there is not yet a single instrument considered to be the gold standard. As a future perspective, there is the urgency of developing a new tool that can widely and completely assess all psychopathological aspects of suicidality.

Improved quality of life and reduced depressive symptoms in medical students after a single-session intervention

Objective: Anxiety and depression are prevalent among medical students. Brazilian medical students have higher levels of depression and lower quality of life than their U.S. counterparts, and no preventive intervention exists for this risk group in Brazil. The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP), a cognitive-behavioral treatment protocol for neuroticism, was recently adapted into a single-session, preventive intervention. This study tested the impact of this protocol on psychiatric symptoms and quality of life in Brazilian medical students. Methods: In this open trial, the intervention protocol was translated and adapted to Brazilian Portuguese. Medical students over 18 years of age without psychotic symptoms, severe depressive episodes, or acute psychiatric risk were included, undergoing a psychiatric clinical interview (Mini-International Neuropsychiatric Interview [MINI]) and evaluation at baseline and at 7 and 30 days after a single-session UP that included experimental avoidance, quality of life, self-esteem, empathy, and anxiety symptom scales. A new evaluation was performed 90 days after the intervention. Results: Sixty-two students participated. Ninety days after the intervention, there were significant reductions in the number of students who met the criteria for social anxiety disorder (p = 0.013) or panic disorder (p = 0.001). There were also significant improvements in depressive symptoms (Beck Depression Inventory, p < 0.001) and quality of life (Quality of Life Enjoyment and Satisfaction Questionnaire, p < 0.001). Conclusion: UP improved anxiety and depressive symptoms in medical students. The single-session group format could reduce costs and facilitate application. Future placebo-controlled studies are necessary to confirm these findings.

WAGRO syndrome: a rare genetic condition associated with aniridia and additional ophthalmologic abnormalities / Síndrome WAGRO: uma condição genética rara associada à aniridia e a anormalidades oftalmológicas adicionais

ABSTRACT Aniridia is a congenital eye disorder with a variable degree of hypoplasia or absence of iris tissue. It is caused by loss of function of the PAX6 gene and may be an isolated ocular abnormality or part of a syndrome. WAGRO refers to a rare genetic condition leading to Wilms tumor, aniridia, genitourinary anomalies, mental retardation, and obesity and is caused by a deletion of the short arm of chromosome 11 (11p), where the PAX6 gene is located. Here, we report on an 8-year-old boy with aniridia, polar cataract, and lens subluxation along with neuropsychomotor and speech delays. Karyotype evaluation showed an interstitial deletion including region 11p13-p14, confirming the diagnosis of WAGRO syndrome. In cases of aniridia, a diagnosis of WAGRO syndrome should be considered.

RESUMO A aniridia é uma doença ocular congênita com grau variável de hipoplasia ou ausência do tecido da íris. É causada pela perda de função do gene PAX6 e pode ser uma anormalidade ocular isolada ou parte de uma síndrome. WAGRO refere-se a uma condição genética rara que leva ao tumor de Wilms, aniridia, anomalias geniturinárias, déficit intelectual e obesidade e é causada por uma deleção do braço curto do cromossomo 11 (11p), onde o gene PAX6 está localizado. Aqui, nós relatamos um menino de 8 anos de idade com aniridia, catarata polar e subluxação do cristalino, além de retardo neuropsicomotor e de fala. A avaliação cariotípica revelou uma deleção intersticial envolvendo a região 11p13-p14, confirmando o diagnóstico da síndrome WAGRO. Em casos de aniridia, um diagnóstico de síndrome de WAGRO deve ser considerado.

Transcranial magnetic stimulation for treatment of major depression during pregnancy: a review / Estimulação magnética transcraniana para o tratamento de depressão maior durante a gestação: uma revisão

Abstract Introduction: Pregnancy is characterized by a high prevalence of mental disorders. Depression is the most common of these disorders and it is a risk factor for negative maternal and child development outcomes. Psychotherapy and pharmacotherapy are conventional and well-established therapeutic options, but some clients fail to respond and the safety of using some pharmacological agents during pregnancy is unclear. Some neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS), have been studied in depressed pregnant women. Objective: To evaluate the safety and efficacy of rTMS for major depression in pregnant women. Methods: The LILACS and PubMed databases were reviewed using the search terms depression, pregnancy and magnetic stimulation. Texts including primary data, published in Portuguese, Spanish, or English, between 1995 and 2014, that evaluated depressed pregnant women and used rTMS as the intervention were selected. Papers lacking sufficient data were excluded. Twenty-two texts were initially identified; after applying the inclusion criteria, 12 were selected and analyzed. Results: The studies reviewed reported satisfactory responses to rTMS in acute depressive episodes, as measured using depressive symptom scales. Remission of symptoms was achieved in many cases. The procedure was well tolerated and there were no reports of damage/complications to unborn children. Conclusion: The data available at this time support the efficacy and tolerability of rTMS for depression in pregnant women. Controlled studies should corroborate this conclusion. This review only included studies in three languages and the resulting sample size was not large enough to conduct a meta-analysis.

Resumo Introdução: A gestação é caracterizada por uma alta prevalência de transtornos mentais. A depressão é a mais comum entre essas doenças e é fator de risco para desfechos negativos maternos e de desenvolvimento da criança. Psicoterapia e farmacoterapia são opções terapêuticas convencionais e bem estabelecidas, mas algumas pacientes não apresentam resposta, e a segurança do uso de alguns psicofármacos durante a gestação não é clara. Algumas técnicas de neuromodulação, como estimulação magnética transcraniana repetitiva ( repetitive transcranial magnetic stimulation , rTMS), vêm sendo estudadas em gestantes com depressão. Objetivo: Avaliar a segurança e a eficácia da rTMS para depressão maior em mulheres gestantes. Métodos: As bases de dados LILACS e PubMed foram revisadas utilizando os termos depressão, gestação e estimulação magnética. Textos originais, publicados em português, espanhol, ou inglês, entre 1995 e 2014, que avaliaram gestantes com depressão e utilizaram rTMS como intervenção, foram selecionados. Artigos com dados insuficientes foram excluídos. Vinte e dois textos foram inicialmente identificados; após a aplicação dos critérios de inclusão, 12 foram selecionados e analisados. Resultados: Os estudos revisados demonstraram resposta satisfatória com rTMS em episódios depressivos agudos, avaliada com escalas de sintomas depressivos. Houve remissão em muitos casos. O procedimento foi bem tolerado e não houve relatos de danos/complicações aos bebês. Conclusão: Os dados disponíveis até o momento sugerem a eficácia e tolerabilidade de rTMS para depressão em gestantes. Estudos controlados devem corroborar esta conclusão. Esta revisão incluiu apenas estudos em três idiomas e resultou em um tamanho amostral insuficiente para conduzir uma metanálise.

Relations between executive functions and different symptomatic dimensions in obsessive compulsive disorder / Relações entre funções executivas e diferentes dimensões sintomatológicas no transtorno obsessivo-compulsivo / Las relaciones entre las funciones ejecutivas y diferentes dimensiones sintomáticas en trastorno obsesivo-compulsivo

There is no consensus in the literature as to neuropsychological functioning, the severity of obsessive-compulsive symptoms (OCS) and the definitions of the OCS dimensions. We conducted a cross-sectional study investigating the relationship between executive function and OCS severity in the various dimensions, according to the Dimensional Yale-Brown Obsessive-Compulsive Scale criteria. We evaluated 28 patients with OCS, using eight neuropsychological instruments to evaluate executive function. We found that OCS severity in the contamination/cleaning dimension correlates negatively with executive function, inhibitory control and attentional control. Severity in the hoarding dimension correlated positively with cognitive flexibility, visual processing and logical reasoning, whereas it correlated negatively with the capacity to develop efficient complex problem-solving strategies. There was also a positive correlation between severity in the symmetry/ordering dimension and attentional control. Our findings suggest that the profile of executive function in OCD is defined by the severity of the various OCS dimensions.

Não há consenso na literatura quanto ao funcionamento neuropsicológico, a gravidade dos sintomas obsessivo-compulsivos (SOC) e as definições de suas dimensões. Realizou-se um estudo transversal para investigar a relação entre as funções executivas e a gravidade dos SOC nas várias dimensões, de acordo com os critérios dimensionais da Escala de Sintomas Obsessivo-compulsivos de Yale-Brown. Foram avaliados 28 pacientes com SOC, por meio de oito instrumentos de avaliação das funções executivas. A gravidade dos SOC, na dimensão contaminação/limpeza, correlacionou-se negativamente com as funções executivas controle inibitório e atenção. A gravidade da dimensão colecionismo foi positivamente correlacionada com a flexibilidade cognitiva, o processamento visual e o raciocínio lógico. Houve uma correlação negativa com a capacidade de desenvolver estratégias eficientes de resolução de problemas. Houve também uma correlação positiva entre a gravidade na dimensão simetria/ordenação e controle da atenção. Resultados sugerem que o perfil de funções executivas no TOC é definido pela gravidade das dimensões dos SOC.

No hay consenso en la literatura sobre el funcionamiento neuropsicológico, la gravedad de los síntomas obsesivo-compulsivos (SOC) y las definiciones de sus dimensiones. Fue llevado a cabo un estudio transversal para investigar la relación entre la función ejecutiva y la gravedad de la SOC en diversas dimensiones de estudio, de acuerdo con los criterios de trastorno obsesivo-compulsivo Escala de Síntomas Dimensión de Yale-Brown. Fueron evaluados 28 pacientes con SOC, utilizando ocho instrumentos para evaluar las funciones ejecutivas. La gravedad de los SOC en la dimensión contaminación / limpieza se correlaciona inversamente con la función ejecutiva control inhibitorio y atención. La gravedad de la dimensión de la recolección se correlacionó positivamente con la flexibilidad cognitiva, el procesamiento visual y el razonamiento lógico. Fue encontrada una correlación negativa con la capacidad de desarrollar estrategias eficaces para la resolución de problemas. Hubo también una correlación positiva entre la gravedad en la dimensión simetría / ordenación y control de la atención. Los resultados sugieren que el perfil de funciones ejecutivas en el TOC se define por la gravedad de las dimensiones de los SOC.

Treating refractory obsessive-compulsive disorder: what to do when conventional treatment fails? / Tratando o transtorno obsessivo-compulsivo refratário: o que fazer quando tratamentos convencionais falham?

Obsessive-compulsive disorder (OCD) is a chronic and impairing condition. A very small percentage of patients become asymptomatic after treatment. The purpose of this paper was to review the alternative therapies available for OCD when conventional treatment fails. Data were extracted from controlled clinical studies (evidence-based medicine) published on the MEDLINE and Science Citation Index/Web of Science databases between 1975 and 2012. Findings are discussed and suggest that clinicians dealing with refractory OCD patients should: 1) review intrinsic phenomenological aspects of OCD, which could lead to different interpretations and treatment choices; 2) review extrinsic phenomenological aspects of OCD, especially family accommodation, which may be a risk factor for non-response; 3) consider non-conventional pharmacological approaches; 4) consider non-conventional psychotherapeutic approaches; and 5) consider neurobiological approaches

O transtorno obsessivo-compulsivo (TOC) é uma doença crônica e incapacitante. Uma pequena porcentagem de pacientes se torna assintomática após o tratamento. O objetivo deste trabalho foi revisar as alternativas terapêuticas para o tratamento de TOC quando os tratamentos convencionais falham. Os dados foram extraídos de estudos clínicos controlados (medicina baseada em evidências) publicados nas bases de dados MEDLINE e Science Citation Index/Web of Science entre 1975 e de 2012. Os resultados são discutidos e sugerem as seguintes abordagens para profissionais que lidam com TOC refratário: 1) rever aspectos fenomenológicos intrínsecos ao TOC, o que pode levar a entendimentos diferenciados e à escolhas terapêuticas distintas; 2) rever aspectos fenomenológicos extrínsecos ao TOC, principalmente acomodação familiar, que pode ser fator de risco para a não resposta; 3) considerar abordagens farmacológicas não convencionais; 4) considerar abordagens psicoterapêuticas não convencionais; e 5) considerar abordagens neurobiológicas

Análise de características vocais e de aspectos psicológicos em indivíduos com transtorno obsessivo-compulsivo / Analysis of vocal characteristics and psychological aspects in individuals with obsessive-compulsive disorder

OBJETIVO: Avaliar a auto-imagem vocal e caracterizar auditiva e acusticamente as vozes de sujeitos com Transtorno Obsessivo Compulsivo (TOC), comparadas a um grupo controle sem queixas psiquiátricas e vocais, além de analisar aspectos psicológicos que possam estar envolvidos nas questões vocais avaliadas. MÉTODOS: Constituiu-se uma amostra de 35 indivíduos, homens e mulheres, com idades entre 16 e 74 anos, sendo 17 com TOC e 18 casos controle. Todos os pesquisados foram submetidos aos seguintes protocolos de pesquisa: Escala de Depressão de Beck, Escala de Ansiedade de Beck e o protocolo para a caracterização da voz de sujeitos com manifestações psiquiátricas. Os sujeitos responderam ainda ao questionário de análise psicodinâmica da voz com enfoque na auto-imagem vocal e foram submetidos à avaliação perceptivo-auditiva e análise acústica da voz. RESULTADOS: Na análise da auto-imagem vocal, os aspectos significativos descritos pelo grupo clínico foram as características vocais triste e ruim. Na avaliação perceptivo-auditiva, houve predomínio do tipo voz rouco-soprosa em grau leve, alterações na ressonância, velocidade de fala e na modulação e entonação. Houve diferenças entre os valores de jitter e shimmer. Não foram observados valores fora do padrão de normalidade com relação ao tremor, nem diferenças entre os grupos quanto aos valores de frequência fundamental. CONCLUSÃO: Foi possível compreender a percepção do indivíduo com TOC sobre sua própria voz e os desvios na emissão vocal. Assim, o fonoaudiólogo pode obter informações que permitam melhorar a qualidade de vida destes por meio de uma intervenção fonoaudiológica, visando, também, a interdisciplinaridade.

PURPOSE: To assess the vocal self-image and to characterize auditory and acoustic aspects of the voices of individuals with Obsessive-Compulsive Disorder (OCD), compared to a control group without psychiatric and vocal complaints, in addition to analyze the psychological aspects that may be involved in the evaluated vocal issues. METHODS: The sample consisted of 35 individuals - 17 with OCD and 18 control cases - of both genders, with ages between 16 and 74 years. All subjects underwent the following research protocols: Beck Depression Inventory, Beck Anxiety Inventory, and the protocol for the characterization of the voices of individuals with psychiatric manifestations. The subjects also answered the voice psychodynamic analysis questionnaire focusing on their vocal self-image, and were submitted to auditory-perceptive evaluation and acoustic analysis of voice. RESULTS: In the analysis of the vocal self-image, the significant aspects described by the clinical group were the vocal characteristics sad and bad. In the auditory-perceptive analysis, there was a predominance of the slightly hoarse, breathy voice, alterations in resonance, speech rate, modulation and intonation. There were differences between jitter and shimmer values. All values regarding tremor were within normal standard parameters, and no differences were found between the groups regarding fundamental frequency values. CONCLUSION: It was possible to understand the perception of individuals with OCD regarding their own voices, and the deviations in vocal emissions. Thus, the speech-language pathologist can obtain information that allows the improvement in the quality of life of these individuals through speech-language pathology intervention, also aiming at interdisciplinarity.

Acomodação familiar e criticismo percebido em pacientes com transtorno obsessivo-compulsivo / Family accommodation and perceived criticism in patients with obsessive-compulsive disorder

OBJETIVO: O transtorno obsessivo-compulsivo (TOC) causa importante impacto sobre a dinâmica familiar. Frequentemente, ocorrem modificações na rotina da família, a qual acaba se adaptando aos sintomas e às exigências do paciente, fenômeno denominado acomodação familiar. Portadores de TOC podem sentir-se, ainda, alvo de críticas por parte de pessoas de seu convívio. Alguns estudos associam pior prognóstico a maiores Índices de Acomodação Familiar e criticismo percebido. Este artigo tem como objetivo verificar possíveis associações entre tipos de sintomas predominantes (dimensões) determinados pela escala DYBOCS, em relação ao funcionamento familiar e percepção crítica dos pacientes. MÉTODO: Quarenta e nove pacientes e seus familiares foram avaliados por meio da aplicação de escalas para medição dos índices de criticismo percebido (Perceived Criticism Scale) e acomodação familiar (Family Accommodation Scale), além de escalas para medir a intensidade dos sintomas obsessivo-compulsivos (Dimensional Yale-Brown Obsessive-Compulsive Scale, Yale-Brown Obsessive-Compulsive Scale), depressivos e ansiosos (Hamilton and Beck depression and anxiety inventories). Compararam-se os resultados aos índices obtidos pela DYBOCS e a outras variáveis clínicas relacionadas ao TOC. RESULTADOS: Encontraram-se correlações estatísticas entre gravidade das dimensões agressividade e contaminação, com maior acomodação familiar. Foi verificado também maior criticismo por parte dos pacientes portadores de colecionismo. CONCLUSÃO: Diferentes subtipos de TOC exercem diferentes padrões de influência no contexto familiar. Mais estudos com esse enfoque são necessários para melhor orientação comportamental a pacientes e familiares.

OBJECTIVE: The obsessive-compulsive disorder causes significant impact on the family function, leading to changes in the routine of the family, which adapt itself according to the symptoms and the requirements of the patient, a family phenomenon known as accommodation. OCD patients may be still subject to criticism by those of its relationships. Some studies evince worse prognosis related to higher rates of family accommodation and perceived criticism. This paper aims to determine possible associations between types of predominant symptoms (dimensions determined by the scale DYBOCS) and the family accommodation and critical perception of the patients. METHOD: Forty-nine patients and their relatives were evaluated by the Perceived Criticism Scale, Family Accommodation Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Yale-Brown Obsessive-Compulsive Scale and the Hamilton and Beck depression and anxiety scales. RESULTS: There was significant statistical correlation between severities of the aggressive and contamination/ cleaning dimensions with higher family accommodation. There was also a higher perceived criticism for patients with hoarding. CONCLUSION: Different contents of obsessive-compulsive symptoms perform different patterns of influence in the family context. These results remain more speculation and studies with proper designs and sample size must be conducted.

The Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders: recruitment, assessment instruments, methods for the development of multicenter collaborative studies and preliminary results / Consórcio Brasileiro de Pesquisa em Transtornos do Espectro Obsessivo-Compulsivo: recrutamento, instrumentos de avaliação, métodos para o desenvolvimento de estudos colaborativos multicêntricos e resultados preliminares

OBJECTIVE: To describe the recruitment of patients, assessment instruments, implementation, methods and preliminary results of The Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders, which includes seven university sites. METHOD: This cross-sectional study included a comprehensive clinical assessment including semi-structured interviews (sociodemographic data, medical and psychiatric history, disease course and comorbid psychiatric diagnoses), and instruments to assess obsessive-compulsive (Yale-Brown Obsessive-Compulsive Scale and Dimensional Yale-Brown Obsessive-Compulsive Scale), depressive (Beck Depression Inventory) and anxious (Beck Anxiety Inventory) symptoms, sensory phenomena (Universidade de São Paulo Sensory Phenomena Scale), insight (Brown Assessment Beliefs Scale), tics (Yale Global Tics Severity Scale) and quality of life (Medical Outcome Quality of Life Scale Short-form-36 and Social Assessment Scale). The raters' training consisted of watching at least five videotaped interviews and interviewing five patients with an expert researcher before interviewing patients alone. The reliability between all leaders for the most important instruments (Structured Clinical Interview for DSM-IV, Dimensional Yale-Brown Obsessive-Compulsive Scale, Universidade de São Paulo Sensory Phenomena Scale) was measured after six complete interviews. RESULTS: Inter-rater reliability was 96 percent. By March 2008, 630 obsessive-compulsive disorder patients had been systematically evaluated. Mean age (±SE) was 34.7 (±0.51), 56.3 percent were female, and 84.6 percent Caucasian. The most prevalent obsessive compulsive symptom dimensions were symmetry and contamination. The most common comorbidities were major depression, generalized anxiety and social anxiety disorder. The most common DSM-IV impulsive control disorder was skin picking. CONCLUSION: The sample was composed mainly by Caucasian individuals, unmarried, with some kind...

OBJETIVO: Descrever o recrutamento de pacientes, instrumentos de avaliação, métodos para o desenvolvimento de estudos colaborativos multicêntricos e os resultados preliminares do Consórcio Brasileiro de Pesquisa em Transtornos do Espectro Obsessivo-Compulsivo, que inclui sete centros universitários. MÉTODO: Este estudo transversal incluiu entrevistas semi-estruturadas (dados sociodemográficos, histórico médico e psiquiátrico, curso da doença e diagnósticos psiquiátricos comórbidos) e instrumentos que avaliam os sintomas do transtorno obsessivo-compulsivo (Escala para Sintomas Obsessivo-Compulsivos de Yale-Brown e Escala Dimensional para Sintomas Obsessivo-Compulsivos de Yale-Brown), sintomas depressivos (Inventário de Depressão de Beck), sintomas ansiosos (Inventário de Ansiedade de Beck), fenômenos sensoriais (Escala de Fenômenos Sensoriais da Universidade de São Paulo), juízo crítico (Escala de Avaliação de Crenças de Brown), tiques (Escala de Gravidade Global de Tiques de Yale) e qualidade de vida (questionário genérico de avaliação de qualidade de vida, Medical Outcome Quality of Life Scale Short-form-36 e Escala de Avaliação Social). O treinamento dos avaliadores consistiu em assistir cinco entrevistas filmadas e entrevistar cinco pacientes junto com um pesquisador mais experiente, antes de entrevistar pacientes sozinhos. A confiabilidade entre todos os líderes de grupo para os instrumentos mais importantes (Structured Clinical Interview for DSM-IV, Dimensional Yale-Brown Obsessive-Compulsive Scale, Universidade de São Paulo Sensory Phenomena Scale ) foi medida após seis entrevistas completas. RESULTADOS: A confiabilidade entre avaliadores foi de 96 por cento. Até março de 2008, 630 pacientes com transtorno obsessivo-compulsivo tinham sido sistematicamente avaliados. A média de idade (±SE) foi de 34,7 (±0,51), 56,3 por cento eram do sexo feminino e 84,6 por cento caucasianos. Os sintomas obsessivo-compulsivos mais prevalentes foram...

Personality traits and treatment outcome in obsessive-compulsive disorder / Traços de personalidade e resposta terapêutica no transtorno obsessivo-compulsivo

OBJECTIVE: Comorbidity with personality disorders in obsessive-compulsive patients has been widely reported. About 40 percent of obsessive-compulsive patients do not respond to first line treatments. Nevertheless, there are no direct comparisons of personality traits between treatment-responsive and non-responsive patients. This study investigates differences in personality traits based on Cloninger's Temperament and Character Inventory scores between two groups of obsessive-compulsive patients classified according to treatment outcome: responders and non-responders. METHOD: Forty-four responsive and forty-five non-responsive obsessive-compulsive patients were selected. Subjects were considered treatment-responsive (responder group) if, after having received treatment with any conventional therapy, they had presented at least a 40 percent decrease in the initial Yale-Brown Obsessive Compulsive Scale score, had rated "better" or "much better" on the Clinical Global Impressions scale; and had maintained improvement for at least one year. Non-responders were patients who did not achieve at least a 25 percent reduction in Yale-Brown Obsessive Compulsive Scale scores and had less than minimal improvement on the Clinical Global Impressions scale after having received treatment with at least three selective serotonin reuptake inhibitors (including clomipramine), and at least 20 hours of cognitive behavioral therapy. Personality traits were assessed using Temperament and Character Inventory. RESULTS: Non-responders scored lower in self-directedness and showed a trend to score higher in persistence than responders did. CONCLUSION: This study suggests that personality traits, especially self-directedness, are associated with poor treatment response in obsessive-compulsive patients.

OBJETIVO: Comorbidade com transtornos de personalidade tem sido extensamente descrita no transtorno obsessivo-compulsivo. Aproximadamente 40 por cento dos pacientes com transtorno obsessivo-compulsivo não respondem a tratamentos de primeira linha. Não obstante, não existem estudos comparando diretamente traços de personalidade entre pacientes responsivos e refratários ao tratamento do transtorno obsessivo-compulsivo. Este estudo investiga diferenças nos traços da personalidade baseados no Inventário de Temperamento e Caráter de Cloninger (TCI) entre dois grupos de pacientes com transtorno obsessivo-compulsivo classificados segundo desfecho terapêutico: responsivos e refratários. MÉTODO: Quarenta e cinco pacientes refratários e 44 responsivos foram selecionados. Os indivíduos foram considerados responsivos se, após tratamento com terapêutica convencional, apresentaram diminuição de ao menos 40 por cento no escore inicial da Yale-Brown Obsessive Compulsive Scale, foram classificados como "melhor" ou "muito melhor" na Clinical Global Impressions; e mantiveram melhora por pelo menos um ano. Os refratários eram os pacientes que não atingiram redução de ao menos 25 por cento na Yale-Brown Obsessive Compulsive Scale e tiveram a melhoria menor que "mínima" na Clinical Global Impressions após o tratamento com ao menos três inibidores seletivos da recaptura de serotonina, incluindo clomipramina, e ao menos 20 horas da terapia cognitiva-comportamental. Os traços da personalidade foram avaliados através do Temperament and Character Inventory. RESULTADOS: Refratários pontuaram menos em autodirecionamento e tenderam a pontuar mais em persistência. CONCLUSÃO: Este estudo sugere que os traços de personalidade, especialmente autodirecionamento, estão associados com a resposta pobre do tratamento em pacientes com transtorno obsessivo-compulsivo.

Fatores preditores de resultados no tratamento do transtorno obsessivo-compulsivo com as terapias comportamental e cognitivo-comportamental: uma revisão sistemática: [revisão] / Outcome predictor factors in the treatment of obsessive-compulsive disorder using behavior and cognitive-behavior therapies: a systematic review: [revision]

INTRODUÇÃO: As terapias comportamental e cognitivo-comportamental reduzem os sintomas do transtorno obsessivo-compulsivo em mais de 70% dos pacientes. Entretanto, cerca de 30% não obtêm nenhuma melhora. Conhecer fatores associados a esses desfechos poderia auxiliar numa melhor indicação do tratamento, incrementando sua eficácia. MÉTODO: Foram revisados trabalhos que investigaram fatores preditivos de resultados nos tratamentos do transtorno obsessivo-compulsivo, nas fontes PubMed, PsycINFO e LILACS. Termos utilizados na busca: predictive factors OR prediction AND obsessive-compulsive disorder AND exposure response prevention OR ritual prevention OR behav* therapy OR cognitive behav* therapy, resultando em 104 artigos. As referências dos artigos foram analisadas, possibilitando maior número de trabalhos revisados. Excluíram-se artigos que utilizaram apenas farmacoterapia e aqueles que não abordavam o tema, resultando em 29 artigos. DISCUSSÃO: As variáveis demográficas parecem exercer papel indireto, destacando-se sexo masculino e ausência de companheiro(a) como fatores de pior prognóstico. Maior gravidade e início precoce dos sintomas indicariam piores resultados. O transtorno esquizotípico comórbido é potencialmente negativo. Sintomas relacionados ao colecionismo e com conteúdo sexual/religioso indicam pior prognóstico. Maior nível de insight, motivação e colaboração com o tratamento são características favoráveis. Maior intensidade da melhora e a remissão completa são preditores para a não-recaída. CONCLUSÃO: A identificação de fatores preditores de resultados está longe de ser esclarecida. É possível que múltiplos fatores, cujas associações são complexas, atuem em conjunto. Os resultados podem depender de fatores não-específicos, ainda não abordados pelos estudos. A heterogeneidade do transtorno obsessivo-compulsivo e das pesquisas e o uso associado de medicamentos dificultam o estabelecimento de conclusões mais definidas.

INTRODUCTION: Behavioral and cognitive-behavioral therapies reduce symptoms of obsessive-compulsive disorder in over 70% of patients. However, about 30% do not show any improvement. The knowledge of factors associated with these outcomes may inform better treatment indications and improve treatment efficacy. METHOD: Review of studies that investigated predictors of obsessive-compulsive disorder treatment results in PubMed, PsychoINFO and LILACS databases. Terms used in the search were predictive factors OR prediction AND obsessive-compulsive disorder AND exposure response prevention OR ritual prevention OR behav* therapy OR cognitive behav* therapy." The search retrieved 104 studies. The references of retrieved studies were also analyzed to ensure that all relevant studies were included. Studies that used only pharmacotherapy or did not discuss the topic under analysis were excluded, and 29 studies met inclusion criteria. DISCUSSION: Demographic variables seem to play an indirect role in treatment results; male sex and not having partner are factors associated with poor prognosis. Greater severity and early symptom onset also indicate poor outcomes. Comorbid schizotypal disorder is potentially negative. Symptoms associated with hoarding and sexual/religious obsessions predict poor prognosis. Greater insight, motivation and collaboration with treatment are favorable characteristics. Greater improvement and complete remission of symptoms are predictors of no relapse. CONCLUSION: The identification of outcome predictors is still far from complete. Multiple factors may contribute to results, and their associations are complex. Results may depend on unspecific factors not yet investigated. Definite conclusions are difficult to reach because of the heterogeneity of obsessive-compulsive disorder and of the studies investigating it and the combined use of drugs.
