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

A fundamental dimension along which all social and personal relationships vary is closeness. The purpose of present study was to investigate the factor structure and Item-Response parameters of the Unidimensional Relationship Closeness Scale. In a descriptive-correlational design and test validation 180 Birjand University students in the first study and 250 students in the second study were selected through multi-stage random sampling and completed the Unidimensional Relationship Closeness Scale (Dibel, Levin & Park, 2012). The data were analyzed by internal consistency, exploratory and confirmatory factor analysis, discrimination and threshold parameters and Item and test information curves. Results showed that the Unidimensional Relationship Closeness scale had a one-factor structure with explained variance of 63.39. Confirmatory factor validity was also confirmed. Cronbach's alpha coefficients were 0.95 and 0.93 and split half coefficients were 0.89 and 0.88, respectively in two studies. The Item-Response parameters were also at the optimum level. It seems that the Unidimensional Relationship Closeness scale, and in particular the structure of its 12 item versions, has a good reliability and validity in students.
