Since its introduction in 1985, the Satisfaction With Life Scale (SWLS; Diener, Emmons, Larsen, & Griffin, ) has been heavily used as a measure of the life satisfaction component of subjective well-being. Scores on the SWLS have been shown to correlate with measures of mental health and to be predictive of future behaviors such as suicide attempts. In the area of health psychology, the SWLS has been used to examine the subjective quality of life of people experiencing serious health concerns. At a theoretical level, extensive research conducted since the last review (Pavot & Diener, ) has more clearly articulated the nature of life satisfaction judgments, and the multiple forces that can exert an influence on such judgments. In this review, we examine the evolving views of life satisfaction, offer updated psychometric data for the SWLS, and discuss future issues in the assessment of life satisfaction.
