Resumen Objetivo. Obtener evidencias de validez empírica y de precisión del Cuestionario de Emociones Positivas para niños. Método. Se realizaron dos estudios. El primero evalúa la estructura subyacente de cinco dimensiones con análisis factorial exploratorio (AFE) y consistencia interna. Tuvo una muestra de 395 participantes de 10 a 13 años de edad (M = 10.96, DT = .72). El segundo pone a prueba el modelo con cuatro y cinco factores mediante el análisis factorial confirmatorio (AFC). Este analiza la validez convergente entre afecto positivo y resiliencia, y divergente entre afecto negativo y estresores cotidianos. Resultados. Se confirma la estructura de cinco factores (X2/df = 3.26, p < .001, CFI = .913, RMR = .069, TLI, = .900, RMSEA = .069) con alta confiabilidad, invarianza factorial y la validez convergente y divergente. Se reportan diferencias entre niños y niñas. Se recomienda continuar con mayor refinamiento del modelo para contar con instrumentos sensibles y relevantes sobre la experiencia emocional positiva en la infancia.
Abstract Objective. The aim of this study was to obtain evidence of empirical validity and accuracy of the Positive Emotions Questionnaire for Children. Method. The first aspect evaluates the underlying structure of five dimensions with exploratory factor analysis (EFA) and internal consistency, with 395 participants aged 10 to 13 years (M = 10.96, SD = .72). The second aspect tests the model with four and five factors with confirmatory factor analysis (CFA) in another sample of 467 participants (M = 11.19, SD = .76). It analyzes the convergent validity between positive affect and resilience, and divergent validity between negative affect and everyday stressors. Results. The five-factor structure (X²/df = 3.26, p < .001, CFI= .913, RMR= .069, TLI, =.900, RMSEA=.069) is confirmed with high reliability, factorial invariance, and convergent and divergent validity. Differences between boys and girls are reported. Further refinement of the model is recommended to have accurate instruments that measure the positive emotional experience in childhood.
