Patrones de victimización por violencia en el noviazgo y consumo de alcohol en adolescentes estudiantes del sur de Jalisco, México / Patterns of dating violence victimization and alcohol consumption among adolescent students from southern Jalisco, Mexico

Resumen Estudios sugieren la presencia de patrones de violencia en las relaciones de noviazgo durante la adolescencia. En la población adolescente mexicana se conoce poco sobre los patrones de abuso cara a cara y digital en el noviazgo y cómo pueden ser explicados por el consumo de alcohol. El objetivo de esta investigación fue identificar los patrones de victimización por abuso en las relaciones de noviazgo y determinar si el consumo de alcohol predice los patrones encontrados. Fue un estudio transversal con alcance explicativo. Participaron 398 adolescentes estudiantes (62.8% mujeres) de 15 a 18 años de edad (M = 16.1 años; DT = 1). Se usó un análisis de clases latentes y se encontraron tres clases: 1) violencia generalizada baja (45%), 2) violencia psicológica moderada y control digital alto (38%) y 3) violencia generalizada alta (17%). Se encontró que el consumo de alcohol se asoció con la pertenencia a la clase de violencia psicológica moderada y control digital alto (β = 0.48, p = .022) y con la pertenencia a la clase de violencia generalizada alta (β = 0.66, p = .004). Es importante considerar, en la generación de intervenciones, la existencia de patrones de violencia en el noviazgo en adolescentes y la influencia que tiene el consumo de alcohol sobre estos.

Abstract Studies suggest the existence of patterns of dating violence during adolescence. In the adolescent Mexican population, little is known about the patterns of face-to-face and cyber dating abuse and to what extent they can be explained by alcohol consumption. The aim of this research was to identify patterns of dating abuse victimization and to determine whether alcohol use predicts the patterns found. It was a cross-sectional study with an explanatory scope. A total of 398 adolescent students (62.8% women) from 15 to 18 years of age (M = 16.1 years; SD = 1) participated in the study. Latent class analysis was used, and three classes were found: 1) low generalized violence (45%); 2) moderate psychological violence and high digital control (38%); and 3) high generalized violence (17%). Alcohol consumption was found to be associated with the membership in the moderate psychological violence and high digital control (β = 0.48, p = .022) and were included in the high generalized violence class (β = 0.66, p = .004). It is important to consider, in the generation of interventions, the existence of patterns of violence in dating relationships among adolescents and the influence that alcohol consumption has on them.

Patrones de violencia en las relaciones de pareja en adolescentes: una revisión sistemática de la literatura / Patterns of Teen Dating Violence. A Systematic Review of the Literature

Resumen Un grupo creciente de investigaciones ha sugerido la existencia de diferentes patrones de violencia en las relaciones de pareja durante la adolescencia. El objetivo de este estudio fue revisar y sintetizar la evidencia científica respecto a patrones de violencia en las relaciones de pareja en adolescentes, a través de una revisión sistemática de la literatura. La búsqueda se realizó en las bases de datos Pubmed, Scopus, SCIELO, EBSCO, Web of Science, Sage Journals, Taylor and Francis Journals, Wiley, y el motor de búsqueda Google Académico; no hubo restricciones en el año de publicación. Se incluyeron investigaciones que analizaron la violencia desde una perspectiva centrada en la persona (e.g., uso de análisis de clases latentes). Para evaluar la calidad de los estudios transversales se usó la herramienta Axis de 20 ítems, y para los estudios longitudinales, la lista de verificación de Tooth et al. (2005) de 33 ítems. Se identificaron 212 estudios y después de elegir por criterios de elegibilidad, se incluyeron 27. Los patrones de violencia con mayor frecuencia fueron: violencia multiforme (34%), victimización o perpetración por violencia psicológica y física (26%), violencia bidireccional psicológica/verbal (26 °/o), baja violencia (26 °%) y alta violencia (23 °/o). Los patrones de violencia se relacionaron con diferentes variables tales como experiencias adversas en la infancia, variables sociodemográficas, relación familiar e indicadores de salud mental. Estos patrones evidencian que la violencia en las relaciones de pareja durante la adolescencia son un fenómeno complejo y multifactorial.

Abstract A growing body of research has suggested different patterns of teen dating violence. The aim of this study was to review and synthesize the scientific evidence on patterns of teen dating violence, through a systematic review of the literature. The search was conducted in the databases Pubmed, Scopus, SCIELO, EBSCO, Web of Science, Sage Journals, Taylor and Francis Journals, Wiley, and the Google Scholar search engine; there were no restrictions on the year of publication. Studies that indicate analyzing violence from a person-centered perspective (e.g., use of latent class analysis) were included. The 20-item Axis tool was used to assess the quality of the cross-sectional studies, and the 33-itemTooth et al. (2005) Checklist was used for longitudinal studies. Two hundred and twelve studies were identified and after screening for eligibility criteria, 27 studies were included. The most frequent patterns of violence were multiform violence (34%), victimization or perpetration by psychological and physical violence (26%), bidirectional psychological/verbal violence (26%), low violence (26%) and high violence (23%). Violence patterns were related to different variables such as adverse childhood experiences, sociodemographic variables, family relationship, and mental health indicators. These patterns show that teen dating violence is a complex and multifactorial phenomenon.

Resultados: Se encontraron índices de ajuste aceptables en el análisis factorial confirmatorio, además se encontró validez convergente y discriminante de los factores, excepto entre los factores de victimización y perpetración de Agresión Directa. Se encontró evidencia de validez divergente con la calidad de vida y convergente con comportamientos de riesgo. La fiabilidad total fue superior a .87. Conclusiones: Los hallazgos sugieren que el CDAQ puede ser un cuestionario útil para evaluar el abuso digital en las relaciones de pareja en jóvenes mexicanos.

Introduction: Cyber dating abuse is a public health problem that requires valid and reliable evaluations. The objective of this study was to cross-culturally adapt and evaluate the psychometric properties of the Cyber Dating Abuse Questionnaire (CDAQ) for Mexican youth. Method: 1158 young students from 18 to 24 years old participated, 62.9 % were women. In the verification of the linguistic equivalence phase, four words from the original version in Spanish were adapted. Results: Acceptable fit indices were found in the confirmatory factor analysis, in addition, convergent and discriminant validity of the factors was found, except between the factors of victimization and perpetration of Direct Aggression. Evidence of divergent validity was found with quality of life and convergence with risk behaviors. Total reliability was greater than .87. Conclusions: The findings suggest that CDAQ could be a useful questionnaire to assess cyber dating abuse among young Mexicans.

[Relationship between face-to-face and digital dating abuse with health-related quality of life among Mexican adolescents]. / Relación entre el abuso cara a cara y digital en el noviazgo con la calidad de vida relacionada con la salud en adolescentes mexicanos.

The purpose of this research was to identify whether there is a relationship between face-to-face and digital dating abuse victimization with health-related quality of life (HRQoL) among adolescent students, adjusted for sex. Three hundred ninety-eight students of 15 to 18 years of age (62.8% female) participated. The following scales adapted to the Mexican adolescent population were applied: Violence in Adolescents' Dating Relationships Inventory, Cyber Dating Abuse Questionnaire and the KIDSCREEN-10. It was found that 55.5% of the respondents reported having been victims of face-to-face and digital abuse. HRQoL scores were lower for women than for men. Using structural equation modeling, a negative, statistically significant association of moderate magnitude was found between dating abuse (face-to-face and digital) and HRQoL. The results suggest that the higher the level of abuse victimization in both face-to-face and digital dating relationships, the lower the HRQoL of adolescent students. The results of this study show the relevance of considering both face-to-face and digital abuse when analyzing the effect of dating violence on the HRQoL.

El objetivo de esta investigación fue identificar si existe relación entre la victimización por abuso cara a cara y digital en el noviazgo con la calidad de vida relacionada con la salud (CVRS) en estudiantes adolescentes, ajustando por sexo. Participaron 398 estudiantes de entre 15 y 18 años de edad (62,8% mujeres). Se aplicaron las siguientes escalas adaptadas a población adolescente mexicana: Violence in Adolescents' Dating Relationships Inventory, Cyber Dating Abuse Questionnaire y el KIDSCREEN-10. Se encontró que el 55,5% reportó haber sido víctima de abuso cara a cara y digital. Los puntajes de CVRS fueron menores para las mujeres a diferencia de los hombres. Mediante un modelo de ecuaciones estructurales se encontró una asociación negativa, estadísticamente significativa y con magnitud moderada entre el abuso en el noviazgo (cara a cara y digital) y la CVRS. Los resultados sugieren que mientras mayor sea el nivel de victimización por abuso en las relaciones de noviazgo tanto cara a cara como digital, menor será la CVRS en las y los adolescentes estudiantes. Los resultados de este estudio muestran la importancia de considerar tanto el abuso cara a cara como el digital cuando se analiza el efecto de la violencia en el noviazgo sobre la CVRS.

O objetivo desta pesquisa foi identificar se existe uma relação entre a vitimização presencial, o namoro digital e a qualidade de vida relacionada à saúde (QVRS) em estudantes adolescentes, ajustado por sexo. Participaram 398 estudantes com idades entre 15 e 18 anos (62,8% mulheres). Aplicaram-se as seguintes escalas adaptadas à população adolescente mexicana: Violence in Adolescents' Dating Relationships Inventory, Cyber Dating Abuse Questionnaire e o KIDSCREEN-10. Verificou-se que 55,5% relataram terem sido vítimas de abuso presencial e digital. A pontuação da QVRS foi menor para as mulheres, em oposição aos homens. Através de um modelo de equações estruturais foi encontrada uma associação negativa, estatisticamente significativa e com magnitude moderada entre o abuso no namoro (presencial e digital) e a QVRS. Os resultados sugerem que quanto maior o nível de vitimização de abuso, tanto nas relações de namoro presencial quanto nos digitais, menor será o QVRS dos estudantes adolescentes. Os resultados deste estudo mostram a importância de considerar tanto o abuso presencial quanto o digital ao analisar o efeito da violência no namoro na QVRS.

Una revisión narrativa de instrumentos de medición de consumo de alimento en niños / A narrative review of instruments for measuring food consumption in children

Resumen La evidencia sobre cómo medir el consumo de alimento en niños muestra que algunos instrumentos no cumplen con los criterios psicométricos de validez y confiabilidad. En algunos casos estas propiedades no se reportan o el índice de confiablidad es menor al que se sugiere en la literatura de diseño de instrumentos. Además de estos problemas una característica común es que se obtiene información de la frecuencia de consumo de los alimentos, pero no sobre cómo se perciben éstos. Es necesario conocer la frecuencia de consumo y cómo se percibe el alimento. Aquí se revisan algunos hallazgos sobre los instrumentos más utilizados para medir consumo de alimento. El propósito es mostrar los avances sobre la creación de un instrumento válido y confiable en México para estimar frecuencia de consumo y percepción del alimento. La hipótesis es que los alimentos considerados saludables serán consumidos más frecuentemente que los que se consideran poco saludables. Para probar el ajuste de la medida se propone usar modelos de ecuaciones estructurales y medidas de confiabilidad como Omega. Un instrumento con estos estándares permitirá generar evidencia científica para luchar contra los problemas de salud como la obesidad y los trastornos alimentarios como la anorexia nerviosa.

Abstract The evidence in Spanish about how to measure food intake in Children scarcely shows that some instruments fail to meet the criterion commonly used to design valid and reliable questionnaires. In specific cases these basic psychometric properties are not reported or even the Cronbach's alpha index is lower than the measurement literature indicates. Regardless this measurement problem, a common characteristic is that only permits obtain data about consumption frequency. To obtain information about how the foods that are consumed are perceived is needed. In this article, some of the main findings about the most common instruments to measure food intake are reviewed. The purpose is to show findings in advance to get a reliable and valid instrument in Mexico to measure frequency of food intake and food perception of those. The hypothesis is that, food perceived as healthy would be consumed more frequently than those perceived as unhealthy. To probe the good of fit index structural equation models are proposed as well as another index of reliability, Omega. An instrument with this standard will allow generate more scientific evidence to struggle epidemic problems like obesity, eating disorders such as anorexia nervosa.

[Suicide-related behavior and health-related quality of life among first-year university students in a Mexican university]. / Comportamientos de riesgo de suicidio y calidad de vida relacionada con la salud en estudiantes que ingresaron a una universidad mexicana.

The objective was to determine if suicide-related behavior (SRB) and health-related quality of life (HRQL) are associated and whether this association is independent of substance use, violence, and sociodemographic variables. It involved a cross-sectional study with 1,229 Mexican university students: 62.4% women; 37.6% men; age 18.2± .6 years. The YRBS and KISDSCREEN questionnaires were applied. The results were as follows: 14.2% students reported despair; 4.7% had suicidal ideation (SI); 4% had suicidal tendencies (ST); and 2.3% had attempted suicide. Multiple logistic regression models show that despair increased the possibility of lower scores in all HRQL domains except economic resources with odds ratio OR (CI 95%) ranging from 1.5 (1.0-2.3) for autonomy to 4.6 (3.1-6.8) for state of mind. The SI increased the possibility of a lower score in relationships with parents and family life (3.9, 1.7-8.9) and in friends and social support (2.9, 1.3-6.4). The ST increased the possibility for lower physical (2.7, 1.2-6.1) and psychological well-being (3.1, 1.3-7.2). HRQL is associated with SRB among Mexican students even after adjustment for substance use and violence. It highlights the fact that despair is negatively associated with different domains of the HRQL of the students.

El objetivo fue determinar si existe asociación entre comportamientos de riesgo de suicidio (CRS) y menor calidad de vida relacionada con la salud (CVRS) y si esta asociación es independiente del consumo de sustancias, violencia y variables sociodemográficas. Estudio transversal, con 1229 estudiantes universitarios mexicanos; 62.4% mujeres y 37.6% hombres, edad 18.2 ± .6 años. Se aplicaron los instrumentos YRBS y KIDSCREEN-52. Presentaron desesperanza 14.2%, ideación suicida (IS) 4.7%, planeación suicida (PS) 4.0% e intento suicida 2.3%. Modelos de regresión logística múltiple muestran que la desesperanza aumentó la posibilidad de menor puntuación en todos los dominios de CVRS excepto en recursos económicos, con odds ratio OR (IC95%) que van de 1.5 (1.0-2.3) para autonomía, hasta 4.6 (3.1-6.8) para estado de ánimo. La IS incrementó la posibilidad de menor puntuación en relación con los padres y vida familiar (3.9, 1.7-8.9) y en amigos y apoyo social (2.9, 1.3-6.4). La PS aumentó la posibilidad de menor bienestar físico (2.7, 1.2-6.1) y psicológico (3.1, 1.3-7.2). En estudiantes mexicanos la CVRS se asocia a los CRS aún después de ajustar por consumo de sustancias y violencia. Se destaca que la desesperanza se asocia negativamente a los distintos dominios de la CVRS de los estudiantes.

Assessment tools of non-suicidal self-injury in adolescents 1990-2016: a systematic review. / Instrumentos de evaluación de la autolesión no suicida en adolescentes 1990-2016: una revisión sistemática.

The purpose of this systematic review was to identify the instruments created or adapted to assess non-suicidal self-injury (NSSI) among adolescents. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) methodology was used. Two individual reviewers analyzed the psychometric properties of instruments published in English or Spanish from 1990 to 2016 considering standardized quality criteria. The PsycINFO, PubMed, ISI Web of Knowledge, Scopus, SciELO, ScienceDirect, and EBSCO databases were consulted. Eighteen studies that created or adapted 11 instruments were selected. Most were developed in the United States or Canada, and none were developed in Latin America. Several studies presented no evidence of the psychometric properties of their instruments. Seven of the 18 studies obtained at least one positive score. The Alexian Brothers Urge to Self-Injure Scale (ABUSI) and the Impulse, Self-harm, and Suicide Ideation Questionnaire for Adolescents (ISSIQ-A) obtained the highest positive scores. The limitation of this study is that only seven databases were employed for the literature search in English and Spanish. The reporting of the psychometric properties of NSSI instruments among adolescents should be improved, and adaptations to Latin American countries should be developed for international comparisons.

Dos revisores independientes analizaron las propiedades psicométricas de los instrumentos publicados en inglés o español desde 1990 a 2016 considerando criterios de calidad estandarizados. Las bases utilizadas fueron PsycINFO, PubMed, ISI Web of Knowledge, Scopus, SciELO, ScienceDirect y EBSCO. Se seleccionaron 18 estudios que crearon o adaptaron 11 instrumentos. La mayoría desarrollados en Estados Unidos y Canadá y ninguno en América Latina. Varios estudios no presentan evidencia de las propiedades psicométricas de los instrumentos. Siete de los 18 estudios obtuvieron al menos una puntuación positiva. El ABUSI y el ISSIQ-A obtuvieron la mayor cantidad de puntuaciones positivas. Las limitaciones de este estudio fueron que la búsqueda se realizó solamente en siete bases de datos y en los idiomas inglés y español. Se sugiere mejorar el reporte de las propiedades psicométricas de los instrumentos de autolesión no suicida en adolescentes y desarrollar adaptaciones a países de América Latina que permitan hacer comparaciones internacionales.

Systematic review of dating violence questionnaires in Ibero-America and evaluation of their measurement properties. / Revisión sistemática de instrumentos de violencia en el noviazgo en Iberoamérica y evaluación de sus propiedades de medida.

Being a victim or perpetrator of dating violence has been associated with poor mental health, substance abuse, and sexual risk behaviors. The aim of this study was to carry out a systematic review and to evaluate the quality of the measurement properties of dating violence questionnaires, created or adapted in Ibero-America from 1981 to 2017, for a population aged 12 to 29 years and published in Spanish, English, Portuguese or French. The search was conducted in PubMed, ISI Web of Knowledge, EBSCO, ScienceDirect, SCOPUS, SciELO and included manual searches. Two independent researchers conducted both the systematic review and the evaluation of measurement properties. Of 5,812 articles identified, 22 studies involving 16 different questionnaires of dating violence were included. In general, the questionnaires showed evidence of internal consistency, content validity and construct validity, although no study presented evidence of criterion validity, reproducibility, sensitivity, or floor and ceiling effects. Among the cross-cultural adaptations, 42% of them included translation, back translation, committee of experts in translation and piloting. Two questionnaires created, CMN and VADRI/Spain-Mexico and two adaptations of the same questionnaire CTS/Brazil-Mexico received the highest scores .

El objetivo fue realizar una revisión sistemática y evaluar la calidad de las propiedades de medida de instrumentos de violencia en el noviazgo, creados o adaptados en Iberoamérica de 1981 a 2017, para población de 12 a 29 años y publicados en español, inglés, portugués o francés. La búsqueda se realizó en PubMed, ISI Web of Knowledge, EBSCO, ScienceDirect, SCOPUS, SciELO y búsquedas manuales. Dos investigadores independientes llevaron a cabo tanto la revisión sistemática como la evaluación de propiedades métricas. De 5,812 artículos identificados, 22 estudios con 16 instrumentos diferentes de violencia en el noviazgo fueron incluidos. En general, hubo evidencia de consistencia interna, validez de contenido y validez de constructo de los instrumentos y ningún estudio presentó evidencia de validez de criterio, reproducibilidad, sensibilidad y efecto piso techo. El 42% de las adaptaciones reportaron traducción, retro traducción, comité de expertos en la traducción y pilotaje. Las puntuaciones más altas las recibieron dos instrumentos creados, CMN y VADRI/España-México y dos adaptaciones del mismo instrumento CTS/Brasil-México .

Abstract Being a victim or perpetrator of dating violence has been associated with poor mental health, substance abuse, and sexual risk behaviors. The aim of this study was to carry out a systematic review and to evaluate the quality of the measurement properties of dating violence questionnaires, created or adapted in Ibero-America from 1981 to 2017, for a population aged 12 to 29 years and published in Spanish, English, Portuguese or French. The search was conducted in PubMed, ISI Web of Knowledge, EBSCO, ScienceDirect, SCOPUS, SciELO and included manual searches. Two independent researchers conducted both the systematic review and the evaluation of measurement properties. Of 5,812 articles identified, 22 studies involving 16 different questionnaires of dating violence were included. In general, the questionnaires showed evidence of internal consistency, content validity and construct validity, although no study presented evidence of criterion validity, reproducibility, sensitivity, or floor and ceiling effects. Among the cross-cultural adaptations, 42% of them included translation, back translation, committee of experts in translation and piloting. Two questionnaires created, CMN and VADRI/Spain-Mexico and two adaptations of the same questionnaire CTS/Brazil-Mexico received the highest scores .

Escala de Estimación del Consumo de Alimentos y Bebidas para Niños: Evaluación de sus propiedades psicométricas / Estimation of Food and Beverages Intake Scale for Children: Evaluation of psychometric properties

Resumen Las estrategias para disminuir el sobrepeso y la obesidad no han tenido el impacto esperado. Se requiere desarrollar mayor conocimiento sobre las variables estimación del alimento y frecuencia de consumo. Por lo tanto, el propósito de este estudio fue examinar las propiedades psicométricas de un instrumento dirigido a evaluar la estimación de alimentos (EAL) y su frecuencia de consumo (FRC) en niños. Participaron 1,090 niños y niñas de 9 años de edad de la región Sur de Jalisco (México), quienes completaron la Escala de Estimación y Consumo de Alimentos en Niños (ECA-N), que consta de dos secciones: EAL y FRC. El análisis factorial exploratorio realizado con 545 de los participantes derivó tres factores para cada sección, mismos que posteriormente fueron corroborados con base a dos análisis factoriales confirmatorios, uno por sección, practicados con la segunda mitad de la muestra (n = 545). Ambos modelos registraron adecuados índices de bondad de ajuste. La versión final de la ECA-N, con 23 ítems, mostró poseer adecuada consistencia interna en sus dos secciones: EAL (α = .86) y FRC (α = .84). Se discute sobre la necesidad de extender el análisis de las propiedades psicométricas de la ECA-N en niños de otras regiones del país.

Abstract The strategies to reduce overweight and obesity have not had the expected impact. It is necessary to develop greater knowledge regard food estimation and intake frequency. Therefore, the purpose of this study was to examine the psychometric properties of an instrument aimed at the evaluation of meals (EM) and its intake frequency (IFR) in children. A total of 1,090 9-year-old boys and girls from the South region of Jalisco (Mexico) answered the Scale of Estimation and Consumption of Foods in Children, which consists of two sections: EM and IFR. The exploratory factor analysis carried out with 545 participants derived three factors for each section, which were subsequently corroborated based on two confirmatory factor analyses, one per section, performed with the second half of the sample (n = 545). Both models registered some goodness of fit indexes. The final version of the scale, with 23 items, showed appropriate internal consistency in its both sections: EM (α = .86) and IFR (α = .84). The need to extend the analysis of the psychometric properties of the scale in children from other regions of the country is discussed.

Bullying and health-related quality of life in children and adolescent Mexican students.

Previous studies have reported a relationship between being a victim of bullying, but no studies have been carried out with Mexican students; notwithstanding the high scores of bullying in Mexico in international rankings. The objective of this study was to analyze the association between being a victim of bullying and lower HRQoL among schoolchildren and adolescents in Mexico. This cross-sectional and correlational study involved 2225 students from 22 elementary, middle and high schools. HRQoL was assessed with the KIDSCREEN-10 questionnaire and bullying with the social adaptation dimension of KIDSCREEN-52. Bivariate associations were evaluated, and a multivariate logistic regression was utilized. The prevalence of victims of bullying was 17.3%. Being a victim of bullying was double the risk of having a lower HRQoL than not being a victim after adjusting for health perception, gender and age, OR 2.3 (1.7-3.1). As the Wilson and Cleary Model of Quality of Life explains, individual characteristics, such as, being a victim of bullying are associated with quality of life. Similar findings in the existing literature imply that bullying is a global phenomenon that impacts the victimized child or adolescent's life in different ways.

Resumo Pesquisas prévias informaram que ser vítima de "bullying" se associa à menor Qualidade de Vida Relacionada com a Saúde (QVRS); mas nenhuma foi realizada em estudantes Mexicanos apesar dos altos índices de "bullying" mostrados para o México nos rankings internacionais. O objetivo deste estudo foi analisar a associação entre ser vítima de "bullying" e QVRS. Este estudo transversal e de correlação incluiu 2225 crianças e adolescentes de 22 escolas de nível básico, médio básico e médio superior. A QVRS foi avaliada com o questionário KIDSCREEN-10 e o "bullying" com a dimensão de aceitação social do KIDSCREEN-52. Analisaram-se as associações bivariadas, verificou-se confusão e interação, e utilizou-se regressão logística multivariável. A prevalência de vítimas de "bullying" foi de 17.3%. Ser vítima de "bullying" obteve um risco de mais do dobro de QVRS inferior que não ser vítima, depois de ajustar pela percepção de saúde, gênero e idade, OR 2.3 (1.7-3.1). No mesmo sentido que o referido pelo Modelo de Wilson e Cleary, em estudantes mexicanos com características individuais como ser vítima de "bullying", associam-se à QVRS, descoberta similar ao encontrado na literatura existente o que implica que o "bullying" é um fenômeno global que se reflete em diferentes aspectos da vida em crianças e adolescentes vitimizados.

Uso de sustancias psicoactivas y calidad de vida relacionada con la salud en adolescentes escolarizados / Psychoactive substances use and health-related quality of life among school age adolescents

Background The use of psychoactive substances among adolescents is a major social and public health concern. Aim To analyze association of substance abuse and multiple drug use with health-related quality of life (HRQOL) in adolescents attending a high school in Valparaiso, Chile. Material and Methods Analytical cross-sectional study conducted in a sample of adolescents attending high school. HRQOL was assessed using KIDSCREEN-52 questionnaire and substance use was measured using the Global school-based student health survey. Participants had to complete online, self-administered, anonymous questionnaires. Multiple logistic regression analyses were conducted to calculate Odd ratios. Results A total of 550 adolescents aged 16 ± 1 years old completed the questionnaires. Thirty nine percent consumed alcohol during the last month, 31% smoked, 33% used marijuana and 33% admitted the use of multiple drugs. High-risk alcohol consumption was associated with a lower perception of psychological well-being, self-perception and school environment. This last dimension was affected in those who admitted marijuana use during the last month. Multiple drug use (three substances) was associated with a lower perception of physical and psychological well-being, self-perception, relationship with parents, family life and school environment. Conclusions High-risk alcohol consumption and multiple drug use (three substances) have a negative impact on the HRQOL of school age adolescents.

[Cross-cultural adaptation of the KIDSCREEN questionnaire to measure health-related quality of life in the 8 to18 year-old Mexican population]. / Adaptación transcultural del cuestionario KIDSCREEN para medir calidad de vida relacionada con la salud en población mexicana de 8 a 18 años.

The scope of this study was to develop the culturally-adapted version of the KIDSCREEN-52 questionnaire for Mexican adolescents aged 8 to 18, and to analyze its reliability and validity. A translation and back translation was carried out from English to Spanish and vice versa. Cognitive interviews were conducted and confirmatory factor analysis (CFA) was used to verify the content validity of the questionnaire. Based on previous studies (i.e. the Argentinian version) mean scores of dimensions were compared to assess construct validity. Reliability was also analyzed. The results showed that the content validity of the version retained the original concepts, duly adapted to the Mexican culture and language. The AFC confirmed the structure of the 10 original dimensions. Two scales achieved the ceiling effect. The instrument's internal consistency was acceptable (ranged from 0.5 to 0.86), and reproducibility obtained low coefficients in 5 dimensions (0.22 to 0.78). The Mexican KIDSCREEN-52 version is equivalent to the original in terms of content, structure, and construct validity. The conclusion was that theKIDSCREEN -52 tool is suitable for application in the Mexican population aged 8 to 18. Further studies are needed to explore its application in clinical settings.
