Análisis psicométrico de la escala parental breve (EPB): Invarianza demográfica y longitudinal en adolescentes Chilenos

The article reports the psychometric analysis of the Escala Parental Breve (EPB), a scale developed from the PSI II (Darling & Toyokawa, 1997). The EPB includes 3 subscales: 2 dimensions of parenting style (parental warmth and demand) and parental monitoring, a parenting practice. A purposive sample of Chilean adolescents was used (second wave N = 1426, 53% female; third wave N = 1342, 51% female; fourth wave N = 879, 51% female), recruited from 6 private, subsidized private, and public schools in the Metropolitan Region of Santiago for a longitudinal study of the development of autonomy in adolescence and the relationships between parents and adolescents. Exploratory factor analysis was used to evaluate the dimensionality of the EPB in the second wave. The results of confirmatory factor analysis of the third wave of data supported the metric invariance of the scale by gender, socioeconomic status, and age. Comparisons between the third and fourth wave provided evidence for the temporal stability of the instrument. The correlations of the instrument's scales with other indicators of parental behavior and adolescent well-being supported the concurrent validity of the EPB.
