Abstract

The Satisfaction with Life Scale (SWLS; Diener et al., 1985) has been a standard measure for over thirty years. However, the concept of life satisfaction has evolved during this period. This study aimed to evaluate the psychometric properties of the Riverside Life Satisfaction Scale (RLSS) among university students. Utilizing a convenience sampling method within a validation design, 210 students from private institutions in Mashhad were recruited. The participants completed the RLSS (Margolis et al., 2019), SWLS (Diener et al., 1985), a short form of the Psychological Well-Being Scale (Reif, 1989), and the Kessler Psychological Distress Scale (Kessler et al., 2002). The study examined content validity, gender confirmatory invariance, as well as convergent and divergent validity, alongside internal consistency and reliability. The Content Validity Ratio (CVR) for the entire scale was 0.87, and the Content Validity Index (CVI) was 0.97. The Cronbach's alpha coefficient was 0.88, and the Spearman-Brown split-half reliability coefficient also stood at 0.88. Confirmatory factor analysis yielded positive results across the entire sample, inclusive of both genders, indicating factorial invariance by gender. Both convergent and divergent validity were confirmed (P
