Psychometric properties of the WHOQOL-SRPB BREF, Brazilian Portuguese version

Objective: To test the reliability and the discriminant and convergent validity of the abbreviated Brazilian Portuguese World Health Organization's Quality of Life Instrument - Spirituality, Religion, and Personal Beliefs module (WHOQOL-SRPB BREF). Methods: In a sample of 404 individuals, we applied a general questionnaire, the WHOQOL-BREF, the long-form SRPB, the Brief Religious-Spiritual Coping Scale (RCOPE), and the Beck Depression Inventory (BDI). Priority was given to the 9-item SRPB assessment: its unidimensionality was tested through confirmatory factor analysis and Rasch analysis. Results: Confirmatory factor analysis of the 9-item SRPB assessment indicated an adjusted model with acceptable fit to data. In the Rasch analysis, general fit measures showed adequate performance. The 9-item SRPB assessment showed good internal consistency (alpha = 0.85), and could differentiate (discriminant validity) between religious and atheist/agnostic respondents (mean = 74.7±14.1 and 56.8±15.5, respectively; t = 6.37; degrees of freedom [df] = 402; p < 0.01) and between non-depressed and depressed respondents (mean = 76.5±12.9 and 67.1±16.5; t = 5.57; df = 190.5; p < 0.01). Correlations (convergent validity) were significant with the positive-RCOPE subscale (r = 0.58, p < 0.01) and the WHOQOL-BREF domains (Pearson coefficient ranging between 0.24 and 0.49; p < 0.01), but were in the negative direction with the negative-RCOPE subscale (r = -0.10, p < 0.05). Correlation with the long-form SRPB domain (r = 0.934) was almost perfect. Conclusion: The Brazilian Portuguese 9-item SRPB has good psychometric properties and confirmed the findings of the long-form Brazilian Portuguese version and the abbreviated English version.

Psychometric properties of the EUROHIS-QOL 8-item index (WHOQOL-8) in a Brazilian sample

Objective: To test the psychometric properties of the EUROHIS-QOL 8-item index in a Brazilian sample. Methods: The sample consisted of 151 patients and 174 healthy controls (n=325). Several psychometric properties were tested. Results: Reliability showed good internal consistency (Cronbach's alpha = 0.81). The measure showed good discriminant validity between patients and healthy controls (mean1 = 3.32, SD1 = 0.70; mean2 = 3.77, SD2 = 0.63, t = 6.12, p < 0.001). Convergent validity showed significant correlations (p < 0.001) between the EUROHIS-QOL 8-item index and all domains of the WHOQOL-Bref (overall r = 0.47; general health r = 0.54; physical r = 0.69; psychological r = 0.62; social relationship r = 0.55; environment r = 0.55) and between the EUROHIS-QOL 8-item index and the domains of the SF-36, except for the social domain (p = 0.38). On Rasch analysis of unidimensionality, general fit measures showed adequate performance. The EUROHIS-QOL 8-item index also showed good fit on confirmatory factor analysis (CFA) (chi-square = 18.46, degrees of freedom [df] = 15; comparative fit index [CFI] = 0.99; root mean square error of approximation [RMSEA] = 0.03; goodness of fit index [gfi] = 0.99; root mean square residual [RMR] = 0.03; p = 24). Conclusion: The EUROHIS-QOL 8-item index showed good psychometric properties. It is a reliable quality of life measure that can be used in Brazilian populations.

Predictors of length of stay in an acute psychiatric inpatient facility in a general hospital: a prospective study

Objective: There have been significant reductions in numbers of psychiatric beds and length of stay (LOS) worldwide, making LOS in psychiatric beds an interesting outcome. The objective of this study was to find factors measurable on admission that would predict LOS in the acute psychiatric setting. Methods: This was a prospective, observational study. Results: Overall, 385 subjects were included. The median LOS was 25 days. In the final model, six variables explained 14.6% of the variation in LOS: not having own income, psychiatric admissions in the preceding 2 years, high Clinical Global Impression and Brief Psychiatric Rating Scale scores, diagnosis of schizophrenia, and history of attempted suicide. All variables were associated with longer LOS, apart from history of attempted suicide. Conclusions: Identifying patients who will need to stay longer in psychiatric beds remains a challenge. Improving knowledge about determinants of LOS could lead to improvements in the quality of care in hospital psychiatry.

Outcomes of inpatients with severe mental illness: a naturalistic descriptive study

Objective: To describe and evaluate the response and predictors of remission during inpatient treatment in a psychiatric unit in a general hospital based on symptomatology, functionality, and quality of life (QoL). Methods: Patients were admitted to a psychiatric unit in a tertiary general hospital in Brazil from June 2011 to December 2013 and included in the study if they met two of the severe mental illness (SMI) criteria: Global Assessment of Functioning (GAF) ≤ 50 and duration of service contact ≥ 2 years. Patients were assessed by the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression (CGI) Severity Scale , GAF, the World Health Organization Quality of Life Instrument – Abbreviated version (WHOQOL-Bref), and specific diagnostic scales. Results: A total of 239 patients were included. BPRS mean scores were 25.54±11.37 at admission and 10.96±8.11 at discharge (p < 0.001). Patients with manic episodes (odds ratio: 4.03; 95% confidence interval: 1.14-14.30; p = 0.03) were more likely to achieve remission (CGI ≤ 2 at discharge) than those with depressive episodes. Mean length of stay was 28.95±19.86 days. All QoL domains improved significantly in the whole sample. Conclusion: SMI patients had marked improvements in symptomatic and functional measures during psychiatric hospitalization. Patients with manic episodes had higher chance of remission according to the CGI.

Escalas psicométricas como instrumentos de rastreamento para depressão em estudantes do ensino médio / Depression rating scales as screening tools for depression in high school students

CONTEXTO: A depressão é uma importante causa de suicídio em adolescentes. Portanto, são necessários instrumentos adequados para o rastreamento da depressão nessa população. OBJETIVO: Avaliar escalas de depressão como instrumentos de rastreamento para depressão em estudantes brasileiros do ensino médio. MÉTODOS: Estudo transversal. Três escalas (BDI, CES-D, e CRS) e um teste para avaliar sintomas psiquiátricos gerais (SRQ) foram aplicados individualmente a 503 estudantes do ensino médio com idades entre 15 e 17 anos. Os resultados foram comparados aos obtidos com os critérios de depressão maior do manual diagnóstico e estatístico de transtornos mentais (DSM-IV). RESULTADOS: A prevalência de depressão maior utilizando-se os critérios do DSM-IV foi de 10,9%. Adolescentes com depressão maior apresentaram escores significativamente mais altos (p = 0,001) no SRQ e nas três escalas avaliadas em comparação ao grupo sem depressão. A sensibilidade e a especificidade para identificar depressão pelo BDI, CES-D e CRS foram, respectivamente, 0,77 e 0,70, 0,75 e 0,73 e 0,82 e 0,71 (curva ROC). Os melhores pontos de corte foram 9 para o BDI, 10 para a CRS e 14 para a CES-D. A frequência de sintomas depressivos foi maior em meninas (aproximadamente 2:1). CONCLUSÃO: Esses achados indicam o uso do BDI, da CES-D e da CRS apenas para o rastreamento, ou como uma avaliação sintomática adicional, da depressão em estudantes do ensino médio. A diferença entre meninos e meninas com relação aos escores nas escalas alerta contra o uso dos mesmos valores de corte para ambos os sexos.

BACKGROUND: Depression is a major cause of suicide among adolescents. Therefore, it is crucial to find suitable depression screening tools for this population. OBJECTIVE: To evaluate the use of depression rating scales as screening tools for depression in a sample of Brazilian high school students. METHODS: A cross-sectional study. Three scales (BDI, CES-D, and CRS) and a screening test for general psychiatric symptoms (SRQ) were administered to a sample of 503 high school students aged between 15 to 17 years. The results were compared to those obtained with the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). RESULTS: The prevalence of major depression using DSM-IV criteria was 10.9%. Adolescents with major depression had significantly higher (p = 0.001) scores in the SRQ and in the three scales analyzed compared to the group without depression. The sensitivity and specificity of BDI, CES-D, and CRS were 0.77 and 0.70, 0.75 and 0.73, and 0.82 and 0.71, respectively, to screen for major depression (ROC curve). The best cutoff values to suggest depression were 9 for BDI, 10 for CSR, and 14 for CES-D. The frequency of depressive symptoms was higher in girls (approximately 2:1). DISCUSSION: The present findings support the use of the BDI, the CES-D and the CRS only for screening or as an additional symptomatic evaluation of depression in high school student. The difference in scale scores between boys and girls warns against the use of the same cutoff values for both sexes.
