RESUMO
BACKGROUND: The development of mental health disorders is common in the university population, and mindfulness-based interventions (MBIs) seem to be effective in addressing them in different contexts. Thus, this study investigated the impact of an 8-week MBI adapted to university students from the Mindfulness-Based Relapse Prevention (MBSR) on different symptoms related to mental health problems, specifically symptoms of anxiety, depression, stress and insomnia. METHODS: University students (n = 136) were randomized into MBI group (n = 71) or wait-list group (n = 65). All participants completed self-administered questionnaires before and after the intervention, and the experimental group answered questionnaires weekly during intervention. Generalized mixed models were used to assess the effects of the intervention. RESULTS: There were improvements in the symptoms of stress (B = 5.76, p < 0.001), depression (B = 1.55, p < 0.01) and insomnia (B = 1.35, p = 0.020) from the beginning of the intervention to the final assessment when it was compared to the control group. No effect was found in respect of trait anxiety. The MBI was found to be effective in reducing important symptoms related to university students' mental health, possibly grounding further research on the intervention's potential of preventing the development of mental disorders. TRIAL REGISTRATION: The research was registered in the Brazilian Registry of Clinical Trials (ReBEC) - number RBR-63qsqx, approved at 09/16/2019.
RESUMO
The aims of the current study were to evaluate the psychometric properties of a short version of the Five Facet Mindfulness Questionnaire (FFMQ-SF-BR) and verify if the addition of wording mechanisms (positive or negative) contributes to the fit of the shortened Brazilian Portuguese version of the FFMQ. Four hundred eight participants answered self-report measurements. Structural equation modelling was employed for both objectives. Adequate model fit was found for the 5-factor FFMQ-SF-BR model, with significant improvements arising from the addition of wording mechanism effects. No evidences of differential item functioning and population heterogeneity were found. Bifactor analysis showed that latent traces are preferred overusing raw sum scores. The FFMQ-SF-BR is suitable to measure mindfulness in the Brazilian population and has the benefits of decreasing data collection length without losing content coverage. (AU)
O presente estudo objetivou avaliar as propriedades psicométricas de uma versão curta em português do Questionário das Cinco Facetas de Mindfulness (FFMQ-SF-BR) e verificar se a adição de mecanismos de formulação dos itens (positivos ou negativos) contribui para o ajuste do modelo em cinco fatores. Quatrocentos e oito participantes preencheram instrumentos de autorrelato. Modelagem de equações estruturais foi aplicada em ambos os objetivos. Índices adequados de ajuste foram encontrados para o modelo em cinco fatores, com melhorias significativas advindas da adição dos mecanismos de formulação dos itens. Não foram encontradas evidências de funcionamento diferencial dos itens ou heterogeneidade populacional. A análise de um modelo bifator demonstrou que valores de traços latentes são preferíveis à soma da pontuação. A FFMQ-SF-BR é adequada para mensurar mindfulness na população brasileira, com os benefícios de diminuir o tempo de coleta sem perda de conteúdo. (AU)

Cuatrocientos ocho participantes completaron instrumentos de autoinforme. Se aplicó el modelo de ecuaciones estructurales a ambos objetivos. Se encontraron índices de ajuste adecuados para el modelo en cinco factores, con mejoras significativas derivadas de los mecanismos de formulación de ítems. No hubo evidencias de funcionamiento diferencial de los ítems o heterogeneidad de la población. El análisis de un modelo bifactorial mostró que los valores de los rasgos latentes son preferibles a la suma puntuaciones. La FFMQ-SF-BR es adecuada para medir el mindfulness en la población brasileña, reduciendo el tiempo de recolección de datos sin pérdida de contenido. (AU)

AIM: As little is known about alcohol and tobacco consumption concordance between older spouses in low- and middle-income countries, the present study aimed to estimate this in older couples from five Latin American countries. METHODS: This study is a secondary analysis of data collected between 2003 and 2007 by the 10/66 Dementia Research Group, from 1451 couples aged over 65 years from Cuba, the Dominican Republic, Peru, Mexico and Puerto Rico. Kappa statistic was used to assess the agreement of the behavior beyond chance, and logistic regression models with meta-analyses were used to estimate the factors associated with concordance. RESULTS: The mean age of the total sample was 74.8 years (SD 6.6). The results showed high levels of agreement rates in relation to drinking and smoking (75.9% and 85% of couples, respectively, did not drink or smoke), which were beyond the agreement expected by chance. Increased age was associated with concordance on both being non-drinkers (OR 1.03, 95% CI 1.01-1.05) and non-smokers (OR 1.05, 95% CI 1.02-1.07); and having a larger social network was associated with less likelihood of the couple being non-drinkers (OR 0.93, 95% CI 0.88-0.98). Attending religious meetings was associated with increased likelihood of the couple being non-smokers (OR 1.19, 95% CI 1.01-1.41). Socioeconomic circumstances were not associated with couples' concordance. CONCLUSIONS: Older Latin American couples have high levels of concordance in drinking and smoking habits, which increases with age, and were not associated with socioeconomic circumstances, but were with social network. This knowledge can assist the development of policies and interventions to promote health among this growing population. Geriatr Gerontol Int 2017; 17: 1849-1857.
