Factor Structure and Convergent Validity of the Long and Abbreviated Versions of the Multidimensional Students’ Life Satisfaction Scale in an Italian Sample

We examined the psychometric characteristics of the long and abbreviated versions of the Multidimensional Students’ Life Satisfaction Scale (MSLSS) in the Italian contexts. In study 1 we assessed the factorial validity and reliability of the long and abbreviated versions of the MSLSS among Italian adolescents, while in study 2 we assessed the convergent validity of the abbreviated Italian version of the MSLSS by examining the associations between life satisfaction and well-established measures of adjustment. Furthermore, we explored the effect of adolescent gender and age on life satisfaction. Participants in the study 1 were 996 adolescents (48 % males) from 14 to 18 years of age (M = 16.0…
