Resumo: We aimed to evaluate the psychometric properties of the Brazilian version of the Patient Health Questionnaire (PHQ-8). A study with a sample of 4,170 individuals (≥ 15 years old) from the urban area. Conglomerate sampling was adopted in two stages (census sectors and streets), with weighting of estimates by sample weights. A structured questionnaire with sociodemographic data, the PHQ - the modules for depression, generalized anxiety disorder and panic disorder - and the Self-Reporting Questionnaire (SRQ-20) were used. In the evaluation of the PHQ-8, we verified the construct validity by analyzing the dimensional structure, convergent validity and internal consistency. We found a linear disorder without losses to maintain the four response categories. The factor analysis found unidimensionality of the depression construct, with strong factor loads, low residual variances, low residual correlation between items, good fit of the model, internal consistency and satisfactory convergent factorial validity (high loads and correlations with other tests/scales of similar constructs). The PHQ-8 has a one-dimensional structure with evidence of good validity and reliability, being suitable for use in the Brazilian population.

Se trata de un estudio con una muestra de 4.170 individuos (≥ 15 años) en un área urbana. El muestreo por conglomerados fue adoptado en dos etapas (sectores censuales y calles) con ponderación de las estimaciones por pesos muestrales. Los instrumentos utilizados fueron un cuestionario estructurado con datos sociodemográficos, el PHQ -con módulos para depresión, trastorno de ansiedad generalizada y trastorno de pánico- y el Cuestionario de Autoinforme (Self-Reporting Questionnaire; SRQ-20). Al evaluar el PHQ-8 se verificó la validez de su construcción a través de su estructura dimensional, validez convergente y consistencia interna. Se encontró un desorden lineal sin pérdidas para mantener las cuatro categorías de respuesta. El análisis factorizado encontró unidimensionalidad del constructo depresión con fuertes cargas factoriales, bajas varianzas residuales, baja correlación residual entre ítems, buen ajuste del modelo, consistencia interna y satisfactoria validez factorial convergente (altas cargas y correlaciones con otras pruebas/escalas de constructos similares). El PHQ-8 tiene una estructura unidimensional con evidencia de buena validez y confiabilidad, y es adecuado para su uso en la población brasileña.O objetivo deste estudo foi avaliar as propriedades psicométricas da versão brasileira do Questionário de Saúde do Paciente (Patient Health Questionnaire; PHQ-8). Realizamos um estudo com uma amostra de 4.170 indivíduos (≥ 15 anos) em área urbana. A amostragem por conglomerado foi adotada em duas etapas (setores censitários e ruas) com ponderação das estimativas por pesos amostrais. Foi utilizado questionário estruturado com dados sociodemográficos, o PHQ - com módulos para depressão, transtorno de ansiedade generalizada e transtorno do pânico - e o Questionário de Autorrelato (Self-Reporting Questionnaire; SRQ-20). Uma desordem linear sem perdas foi encontrada para manter as quatro categorias de resposta. A análise fatorial revelou unidimensionalidade do construto depressão com cargas fatoriais fortes, baixas variâncias residuais, baixa correlação residual entre os itens, bom ajuste do modelo, consistência interna e validade fatorial convergente satisfatória e altas correlações com outros instrumentos de construtos semelhantes. O PHQ-8 possui estrutura unidimensional com evidência de boa validade e confiabilidade, sendo adequado para uso na população brasileira.Reports in Public HealthCadernos de Saúde Pública2022-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/8073Reports in Public Health; Vol. 38 No. 6 (2022): JuneCadernos de Saúde Pública; v. 38 n. 6 (2022): Junho1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/8073/18092https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/8073/18093Iracema LuaKatia Santana FreitasJules Ramon Brito TeixeiraMichael Eduardo ReichenheimMaura Maria Guimarães de AlmeidaTânia Maria de Araújoinfo:eu-repo/semantics/openAccess2024-03-06T15:30:20Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/8073Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:09:15.591362Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
