Validation of a portuguese version of the students' life satisfaction scale

Abstract

The paper describes the development of the Portuguese version of the Students' Life Satisfaction Scale and the examination of its psychometric properties. A sample of 367 Portuguese students completed the Students' Life Satisfaction Scale (SLSS; Huebner in Sch Psychol Int 12:231-240, 1991a), Children's Hope Scale (CHS; Synder in J Pediatr Psychol 22:399-421, 1997), Global Self-Worth Sub-scale (Harter, S. (1985). Manual for the self-perception profile for children. Denver: University of Denver) and Mental Health Inventory-5 (MHI-5; Berwick et al. in Medical Care 29:169-176, 1991). The first step includes translation, back-translation, inspection for lexical equivalence and content validity, and cognitive debriefing. Then we considered reliability, factor structure, and criterion-related validity. The validation process of the Portuguese SLSS version shows psychometric properties similar to the English language SLSS, suggesting that it measures the same construct in the same way. Implications of these findings are discussed. (c) 2007 Springer Science + Business Media BV/The International Society for Quality-of-Life Studies (ISQOLS).
