Abstract Current study was aimed to translate Relationship Social Comparison Measure (RSCM) into Turkish and test psychometric properties of the Turkish version. RSCM was originally developed as a one factor scale by LeBeau and Buckingham (2008) in order to assess the frequency of relationship social comparison and circumstances under which comparison occur. However, principal component factor analyses suggested two factor solutions, namely General Tendency (= .94) and Partner Attributions (= .86), showing the presence of two constructs tapping different aspects of relationship social comparison. Suggested factor structure of RSCM was also tested with a confirmatory factor analysis, and results supported the two-factor solution (S-B χ 2 (167) = 275.13, p = .00, S-B χ2/df = 1.65, CFI = .95, RMSEA = .05, 90% CI [.04, .06]). The Turkish version of RSCM has high internal reliability as its original form (= .94). Moreover, the results strongly supported convergent validity with relationship satisfaction, investment, and quality of alternatives. Adaptation of RSCM in Turkish will provide an important tool for studies related to RSC in Turkey with strong psychometric properties. By doing so, it was expected to make scientific contributions to the studies related to romantic relationships in Turkey.
