Psychometric Properties of Relationship Scales Questionnaire in Iranian Female Students

Objective: In recent decades, researchers have designed various tools for assessment and study of the interpersonal relationships from an attachment perspective. The purpose of this study was to evaluate the psychometric properties of the relationship scales questionnaire (RSQ), which is one of these tools. Methods: A total of ۳۶۸ female undergraduate students of Ferdowsi University of Mashhad (academic year ۲۰۱۲-۱۳) were selected by quota sampling method from all colleges of the university and were tested by RSQ. Internal consistency method was used to check the reliability of the questionnaire and exploratory factor analysis to assess its construct validity by SPSS ۱۹. Results: The exploratory factorial analysis of RSQ showed ۲ different patterns. The Collins and Read ۳-factor model showed ۴۰.۱۶% of the total variance, and Simpson ۲-factor model determined ۳۵.۳۶% of the total variance. The Cronbach α coefficients were ۰.۶۷ for ۲-factor model, and ۰.۵۷ for ۳-factor model. Conclusion: Both analyzed models showed a relatively average validity for the Iranian version of this questionnaire. Moreover, the ۳-factor model had a higher acceptable validity.
