Positive Psychological Functioning Scale in Spanish Adolescents (PPF-A)

Abstract

We are presenting the adaptation and validation of a Positive Psychological Functioning scale in Spanish adolescents in a sample of 1,858 (M = 14.50 years, SD = 2.87 years), previously developed for adults (Merino & Privado, 2015b). The adaptation presents a hierarchical structure of one general factor and 11 of first order that suitably explain the data (GFI = 0.966, NFI = 0.966, SRMR = 0.053). The reliability (internal consistency and test-retest) is adequate. Evidence of convergent and discriminant validity of the test was found with other measures of subjective well-being, psychological well-being, positive and negative affect, and personality. The test has predictive validity on clinical symptoms (R2 = 0.17) and there are no differences in the measure based on sex and the period of adolescence considered (early, middle and late). Finally, scales for the sample evaluated are provided. Presentamos la adaptación y validación de una escala de Funcionamiento Psicológico Positivo en adolescentes españoles en una muestra de 1.858 (M = 14.50 años, DT = 2.87 años), previamente desarrollada para adultos (Merino & Privado, 2015b). La adaptación presenta una estructura jerárquica de un factor general y 11 de primer orden que explican adecuadamente los datos (GFI = 0.966, NFI = 0.966, SRMR = 0.053). La fiabilidad (consistencia interna y test-retest) es adecuada. Obtuviomos pruebas de la validez convergente y discriminante con otras medidas de bienestar subjetivo, bienestar psicológico, afecto psicológico, afecto positivo y negativo, y personalidad. El test tiene validez predictiva de los síntomas clínicos (R2 = 0.17) y no existen diferencias en la medida en función del sexo y del periodo de la adolescencia considerado.
