The study of interpersonal relations from attachment point of view is a topic that has drawn the attention of researchers in the recent decades and various tools have been devised for its assessment. In this research, we study the psychometric characteristics of the Relational Scales Questionnaire (RSQ) as one of these tools. The studied sample consists of 368 female students of bachelor’s program at Ferdowsi University of Mashhad in academic year 2012-2013. The sample was selected by quota sampling method from among all faculties of this university. The sample was tested by Relational Scales Questionnaire (RSQ). Internal consistency was used in order to study reliability of questionnaire. The exploratory factorial analysis method was used to assess its construct validity. The exploratory factorial analysis of the Relational Scales Questionnaire showed two different patterns. The Collins and Rid three-factor Model showed 40.16% of the total variance, and Simpson two-factor Model determined 35.36% of total variance. Cronbach’s alpha coefficient was 0.67 for two-factor model, and 0.57 for three-factor model. Both of the analyzed models showed a relatively average validity for the Iranian version of this questionnaire. Moreover, the three-factor model had a higher acceptable validity.
