O PHQ-9 parece ter uma estrutura unidimensional, validade e confiabilidade adequadas, e pode ser Гєtil em contextos epidemiolГіgicos e de pesquisa. Os resultados da anГЎlise fatorial dos itens do PHQ-9 identificaram, e a anГЎlise fatorial confirmatГіria confirmou, um Гєnico fator, chamado depressГЈo geral. O PHQ-9 apresentou correlaГ§ГЈo de 0,64 com PHQ-15, в€’0,35 com WHO-5 e 0,70 com BDI-13, indicando boa validade do construto e dos critГ©rios relacionados. O О± de Cronbach para PHQ-9 foi 0,88, e a confiabilidade teste-reteste de uma semana 0,79. O escore mГ©dio do PHQ-9 foi 12,83 (desvio padrГЈo=6,25), indicando depressГЈo moderadamente severa na amostra. Os dados foram analisados por estatГstica descritiva, О± de Cronbach, coeficiente de correlaГ§ГЈo de Pearson, anГЎlise de componentes principais e anГЎlise fatorial exploratГіria e confirmatГіria. Os pacientes completaram o PHQ-9, Patient Health Questionnaire-15 (PHQ-15), the World Health Organization-five Well-Being Index (WHO-5) e a forma abreviada do Beck Depression Inventory-13 (BDI-13). Uma amostra de conveniГЄncia de 130 pacientes psiquiГЎtricos ambulatoriais iranianos foi selecionada em clГnicas psiquiГЎtricas e psicolГіgicas. Um estudo transversal foi conduzido para investigar a validaГ§ГЈo da versГЈo persa do PHQ-9. O PHQ-9 nГЈo teve sua validade examinada em contextos psiquiГЎtricos e psicolГіgicos no IrГЈ. Tem sido usado em pesquisa e na prГЎtica clГnica primГЎria e em outros contextos clГnicos e nГЈo clГnicos. O Patient Health Questionnaire-9 (PHQ-9) Г© uma ferramenta breve de triagem e diagnГіstico para depressГЈo.

Based on previous literature and on the present findings, the PHQ-9 may have applicability to other contexts in the studied population, but this needs to be confirmed by other studies.Дepression validity reliability factorial structure Patient Health Questionnaire-9 psychiatric outpatients Iran The PHQ-9 appears to have a unidimensional structure, adequate validity and reliability, and can be useful in epidemiological/research settings. The results of the factor analysis of PHQ-9 items identified and confirmatory factor analysis confirmed a single factor labeled general depression. The PHQ-9 correlated 0.64 with PHQ-15, в€’0.35 with WHO-5, and 0.70 with BDI-13, indicating good construct and criterion-related validity. Cronbach's О± coefficient for PHQ-9 was 0.88, and one-week test-retest reliability 0.79.

Mean score of the PHQ-9 was 12.83 (standard deviation = 6.25), indicating moderately severe depression in the sample. Data were analyzed by descriptive statistics, Cronbach's О±, Pearson correlation coefficient, principal component analysis, exploratory factor analysis, and confirmatory factor analysis.

They completed the PHQ-9, the Patient Health Questionnaire-15 (PHQ-15), the World Health Organization-five Well-Being Index (WHO-5), and the short form of the Beck Depression Inventory-13 (BDI-13).

A convenience sample of 130 Iranian volunteer psychiatric outpatients was selected from psychiatric and psychological clinics. Methods:ДЄ cross-sectional study was conducted to investigate the validation of the Farsi version of the PHQ-9. The PHQ-9 has not had its validity examined in psychiatric and psychological settings in Iran. It has been used in research and clinical practice in primary care and other clinical and non-clinical settings. The Patient Health Questionnaire-9 (PHQ-9) is a brief screening and diagnostic tool for depression.
