Abstract
OBJECTIVE: To evaluate the reliability and validity of the Brazilian version of the Pittsburgh Sleep Quality Index. METHODS: 309 adolescents, subdivided into a sample of 209 subjects, of whom 25 were reassessed, and another sample of 100 adolescents. Reliability was assessed using Cronbach's α-values, intraclass correlation coefficient, Standard Error of Measure, Minimum Detectable Change, and Bland-Altman plotting. Exploratory analysis of the questionnaire components was performed based on the sample of 209 adolescents. Confirmatory factor analysis was performed with a sample of 100 individuals. RESULTS: The sample of 209 participants had a mean age of 14.38 (±1.94) years, comprising 80 (38.3%) girls and 129 (61.7%) boys. The sample of 100 adolescents had a mean age of 13.66 (±2.35) years, comprising 51 (51%) girls and 49 (49%) boys. The questionnaire obtained a Standard Error of Measure=1.12 and Minimum Detectable Change=3.10. Cronbach's α was 0.71 and the Intraclass Correlation Coefficient was 0.65 (95% CI: 0.21-0.85). The factor analysis showed that the best model of components was the one that consisted of two factors, excluding the component on the use of sleep medications. CONCLUSION: The questionnaire showed high internal consistency and moderate reliability. Furthermore, a model with two factors seems to be the most appropriate to evaluate the quality of sleep in adolescents.
