Background: The Satisfaction with Life Scale is one of the most widely used scales to measure the global cognitive judgment of satisfaction with one’s life. Method: This study assesses the equivalence of the SWLS across Spanish and Portuguese adolescents, using multi-sample Confirmatory Factor Analysis. Participants were Spanish (N = 2183) and Portuguese (N = 4082) junior high school. Results: The results provide high support for the internal consistency of both the Spanish and Portuguese versions of this scale. The results also showed that factor structure, factor loadings, could be considered invariant across groups. However, the full scalar invariance between Spanish and Portuguese samples was not found, with the intercept for SWLS item 5 varying across countries. Conclusions: Similar findings have also been found in other cross-national studies with this scale. Implications of the findings are discussed and we conclude that the Spanish and Portuguese versions of the SWLS can be used for cross-national comparisons with Spanish and Portuguese adolescents.

Invarianza factorial de la Escala de Satisfacción con la Vida en adolescentes de España y Portugal. Antecedentes: la Escala de Satisfacción con la Vida es una de las escalas más utilizadas para medir el juicio cognitivo global sobre la propia satisfacción con la vida. Método: este estudio evalúa la equivalencia de la “SWLS” en adolescentes españoles y portugueses con Análisis Factorial Confirmatorio multi-muestra. Los participantes fueron alumnado español (N = 2.183) y portugués (N = 4.082) de Educación Secundaria. Resultados: los resultados proporcionan un elevado apoyo a la consistencia interna de las versiones en español y portugués de esta escala. Los resultados también mostraron que la estructura factorial y pesos factoriales podría considerarse invariable entre los grupos. Sin embargo, no se obtuvo la invariancia escalar completa entre las muestras de España y Portugal, con el intercepto para el ítem 5 variando entre los países. Conclusiones: otros estudios internacionales con esta escala han encontrado resultados similares. Se discuten las repercusiones de las conclusiones y se establece que las versiones en español y portugués de la “SWLS” pueden ser utilizadas para las comparaciones entre países con adolescentes españoles y portugueses.
