Satisfaction with life scale: Analysis of factorial invariance for adolescents and elderly persons

The purpose of this work is to analyze the factorial invariance of the Sati sfaction With Life Scale across samples of adolescents and elderly persons. Data from 266 subjects were analyzed. Half were Spanish junior high-school students (65 girls and 68 boys) and the other half were Spanish elderly pe ople (68 women and 65 men. Single-group analyses showed an acceptable one-f actor model for both adolescent and elderly groups. Sequential multigroup a nalyses to rest the equivalence of factor structures for adolescent and eld erly groups showed that factor loadings and variances are nor invariant. Th e scale is sensitive to age in these groups.
