Psychometric Properties of the Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS) in Chilean Students (10-12 years old)

This paper analyzes the psychometric properties of the Brief Multidimensional Students' Life Satisfaction Scale-BMSLSS (Seligson, Huebner and Valois, 2003) in Chilean children. 1096 Chilean students of 10, 11 and 12 years-old participated in the study. Reliability analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and item correlation with total score were performed. Results show acceptable internal reliability of the scale (alpha = 0.7), a single factor structure of the scale and appropriate item correlation with total score (between 0.55 and 0.73) This study supports the use of the BMSLSS in children in Chile in the school context, and also provides measurement tools for social indicators for children in Spanish-speaking developing countries.
