This article analyzes the psychometric properties of the Huebner's SLSS in a sample of Chilean boys and girls. 1096 students participated in the study who had between 10 and 12 years old (M= 11; SD= 0.89) and attended public, semiprivate, and private schools in Santiago, Valparaiso and Concepcion. The analysis includes reliability analysis of internal consistency, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Results show an acceptable reliability of the scale (alpha =.86), and factor analysis indicates two factors in the factor structure of the scale that correspond to life satisfaction and desire of change. The discussion examines the bi-factor solution of the model because this finding does not fit the conclusions of previous research. This study expands the utilization of the SLSS in child population contributing to the development of assessment tools for social indicators that consider the self-report of subjective well-being in Chilean children.
