Psychometric properties of the short version of the Five Facets of Mindfulness Questionnaire in brazilian portuguese / Propriedades psicométricas da versão curta do Questionário das Cinco Facetas de Mindfulness em português / Propiedades psicométricas de la versión corta del Cuestionario de las Cinco Facetas de Mindfulness en portugués

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)

Drug Use Frequency Variation and Mental Health During the COVID-19 Pandemic: an Online Survey.

In December 2019, a new disease caused by a coronavirus was first identified in China and quickly spread across the world, causing a large number of deaths. Quarantine has been implemented in many countries as a measure to prevent the spread of the disease. The impact of this situation on drug use and mental health is still poorly understood. Therefore, this cross-sectional study sought to assess possible associations between quarantine, the use of psychoactive substances, and symptoms of depression and anxiety. The assessment instruments used were the Patient Health Questionnaire-9 (PHQ-9); the General Anxiety Disorder-7 (GAD-7) scale; and an adaptation of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The sample consisted of 2398 participants who met the following inclusion criteria: being in quarantine, aged 18 years or older, and living in Brazil. There was a decrease in the frequency of use of practically all drugs investigated in the evaluated sample. However, some factors were associated with less variations in the frequency of substance use before and during quarantine. These factors were being male, single, and having an occupation different from homemaker.
