| Popis: | Objective There is a need for brief, psychometrically sound instruments to assess adolescent sleep, particularly for ethnic minority and economically disadvantaged adolescents. A 10-item short version of the Adolescent Sleep–Wake Scale was recently proposed based upon exploratory factor analysis with primarily Caucasian healthy adolescents from middle- to high-income families. The aim of this study was to expand the utility of the short version of the Adolescent Sleep–Wake Scale by investigating the empirical and construct validity of the measure on an ethnically diverse sample of adolescents from an economically disadvantaged community. Materials and Methods Participants included 467 adolescents (40% African American, 35.5% Caucasian, 16.5% Latino, and 7.9% multiethnic), aged 12–18 years (mean = 15.27 years, SD = 1.96 years), who completed the Adolescent Sleep–Wake Scale. A confirmatory factor analysis (CFA) was conducted with Mplus 7 based on the three-factor solution proposed by Essner et al. (2014). Results CFA indicated that the three-factor structure was a good fit for the data (χ 2 (29) = 52.053, p = 0.005, root mean square error of approximation (RMSEA) = 0.04, CFI = 0.98, TLI = 0.96, standardized root mean residuals (SRMR) = 0.03), and factor loadings for each item were >0.40. Cronbach's alphas by ethnicity indicated that the scale has acceptable reliability (0.70 ≤ α ≤ 0.90) for African American, Caucasian, and multiethnic adolescents, but not for Latino adolescents. Conclusion Our results support the use of the Adolescent Sleep–Wake Scale short form for the majority of ethnic minority and economically disadvantaged adolescents. |
