Subjective well-being in adolescence: New psychometric evidences on the satisfaction with life scale

Abstract

The main purpose of the present study was to test the psychometric properties of the Satisfaction with Life Scale (SWLS) in a large sample of Spanish adolescents. The sample consisted of 1020 non-clinical adolescents with a mean age of 15.96 years (SD = 1.68). The level of internal consistency of the SWLS Total score by means of McDonald’s Omega was .85. The one-dimensional model displayed appropriate goodness of-fit indices. Strong measurement invariance for the one factor model across age and gender was found. Younger adolescents reported higher levels of life satisfaction. In addition, SWLS total score was negatively associated with behavioural and emotional. The study confirmed that the SWLS is a useful tool for the screening of self-reported life satisfaction in adolescents.
