The aim of this study is to validate and test the factorial invariance of the Spanish version of the Satisfaction with Life Scale (SWLS) across genders and some demographic groups, including students, workers, retired people, and housekeepers on a national sample of Chileans (N = 1500). Results suggest the proposed Spanish operationalization of the SWLS is a valid and reliable instrument for measuring global life satisfaction in Chile. Confirmatory factor analysis shows support for a single-factor structure of the SWLS across all groups. Cronbach's alpha coefficient ranges between 0.66 and 0.84 for different groups, with an average a value of 0.80 for the total sample. The SWLS scores converge with an alternative single-item measure of life satisfaction and with measures of the conceptually related constructs. Results also show that the factorial structure of the scale is invariant with respect to gender and across some demographic groups (workers, retired people, and housekeepers). We only find partial factorial invariance across students-workers, students-retired, students-housekeepers, and workers-housekeepers. Mean levels of life satisfaction can be compared across genders and between workers, retired, and housekeepers; it can also be compared, albeit cautiously, between workers and housekeepers and also between students and the three other demographic groups studied.
