Psychometric properties and factorial invariance of the satisfaction with life scale in Latino immigrants in Chile, Spain, and United States

Background: Satisfaction with Life Scale (SWLS) is the most widely used instrument to assess subjective wellbeing in different populations. Aim: The purpose of the present investigation was to evaluate the psychometric properties and the factorial invariance of the SWLS in Latino immigrants living in Chile, Spain, and the United States. Method: A total of 662 participants over the age of 18 and who have lived in the host country for more than a year participated. Results: The results provide evidence of good internal consistency through Cronbach's alpha and McDonald's omega. Also, there is evidence for the unifactorial structure of the instrument through confirmatory factor analysis and its invariance at the configural, metric, and scalar. Conclusions: It is concluded that SWLS is an invariant and reliable measure to study life satisfaction in Latino immigrants in western countries.
