The Investigating of Psychometric properties of Covert Relational Aggression Scale

This study examined the psychometric properties of CRAS of Nelson & Carol (2006) in Iranian couples..
The research was a descriptive-survey study.The study population was composed of married couples in Birjand city.In this study, 350 couples (700) were selected among Birjand couples using available sampling method,& CRAS of Carole & Nelson(2006),revised marital conflict questionnaire of Sanaei (2008) & marital adjustment questionnaire of Spinner (1976) were used. To analyze the data, the statistical indices of Pearson correlation, Cronbach's alpha coefficient, and exploratory factor analysis (using spss 23 software),& confirmatory factor analysis (using AMOS 23software) were used.
Exploratory factor analysis showed that the 12-item CRAS in Iranian sample has been saturated from two factors (social Love withdrawal and social sabotage) explaining 56 percent of the scale variance. Confirmatory factor analysis also showed that two-factor model of CRAS has good fitness with data (AGFI =0.93, NFI =0.94, RMSEA =0.06). Cronbach's alpha coefficient was obtained 0.85, convergent validity was obtained 0.4, and divergent validity was obtained -0.42 that all of them were significant at P≥0.01.
In general, the results showed that CRAS of Carole & Nelson (2006) has good validity & reliability & it can be used to measure the CRA of couples.
