[Validation of Satisfaction with Life Domains Scale in Quebec]

This article presents the results of the Quebec validation of the Satisfaction With Life Domains Scale: This scale was developed in the United States for the general population and adapted for severely mentally ill individuals. Two hundred and sixty six individuals from the general population and 245 severely mentally ill persons participated in this study. Factor analysis allowed the identification of four sub-scales for the clinical population and five for the general population. The scale (alpha = 0.90) and the sub-scales (alpha between 0.60 et 0.84) show excellent internal consistencies and the test-retest reliability was good (r = 0.73). Moreover, analysis of the variance and the discriminant analysis allow to acknowledge that the sub-scales have a high discriminating power; they allow to distinguish the general population from welfare recipient and people suffering from psychosis. The overall results suggest that l'Echelle de satisfaction des domaines de vie have good psychometric properties and can be considered as a valid instrument for assessing subjective quality of life in descriptive or evaluative studies.
