The Investigating of Psychometric properties of Covert Relational Aggression Scale

Objective:This study examined the psychometric properties of CRAS of Nelson & Carol (۲۰۰۶) in Iranian couples.. Method: The research was a descriptive-survey study.The study population was composed of married couples in Birjand city.In this study, ۳۵۰ couples (۷۰۰) were selected among Birjand couples using available sampling method,& CRAS of Carole & Nelson(۲۰۰۶),revised marital conflict questionnaire of Sanaei (۲۰۰۸) & marital adjustment questionnaire of Spinner (۱۹۷۶) were used. To analyze the data, the statistical indices of Pearson correlation, Cronbach's alpha coefficient, and exploratory factor analysis (using spss ۲۳ software),& confirmatory factor analysis (using AMOS ۲۳software) were used.Results: Exploratory factor analysis showed that the ۱۲-item CRAS in Iranian sample has been saturated from two factors (social Love withdrawal and social sabotage) explaining ۵۶ percent of the scale variance. Confirmatory factor analysis also showed that two-factor model of CRAS has good fitness with data (AGFI =۰.۹۳, NFI =۰.۹۴, RMSEA =۰.۰۶). Cronbach's alpha coefficient was obtained ۰.۸۵, convergent validity was obtained ۰.۴, and divergent validity was obtained -۰.۴۲ that all of them were significant at P≥۰.۰۱.Conclusion: In general, the results showed that CRAS of Carole & Nelson (۲۰۰۶) has good validity & reliability & it can be used to measure the CRA of couples.
