Object relations have A key role in psychoanalytic approach. Thus providing a persian version of a scale to assess object relations is helpful for elaborating empirical studies in this approach. the aim of the present study is to investigate validity, reliability, and factorial structure of the Persian version of the Bell object relations inventory (BORI). convenience sampling is used to select 558 students from the university of Tehran. First, by the method of translation- back translation, the Persian version of BORI is prepared. then BORI and defense mechanism questionnaire (DSQ) are completed by the sample. Data analysis is performed by using of Pearson correlation coefficients, parallel, and exploratory factorial analysis. Factorial analyses show four factors named egocentricity, alienation, insecure attachment, and social incompetence. Cronbach Alpha and split-half coefficients are 66/0-77/0 and 60/0-77/0, respectively. significant correlations between object relations and defense mechanisms shows convergent and divergent validity of BORI. Accordingly, the reliability and construct validity of the Persian version of BORI are confirmed. Therefore, BORI for psychological research among Iranian samples is suitable.
