Abstract

Abstract
Introduction: The Self-Ambivalence Measure (SAM) is a relatively new instrument designed to measure self-ambivalence in the context of obsessive-compulsive symptoms. The aim of present study was to investigate the psychometric properties of the SAM-Persian version.
Method: Applying a descriptive-correlational research method a sample with 280 participants were selected from undergraduate students of Shiraz universities on a voluntary basis. The participants completed the Persian version of Self-Ambivalence Measure, Rumination- Reflection Questionnaire (RRQ) and The Rosenberg Self-Esteem Questionnaire (RSE). The factor structure of SAM was investigated using exploratory factor analysis. The Cronbach’s alpha and Spearman-Brown coefficient were computed to obtain the reliability measures. Convergent validity of SAM was examined by the patterns of correlations between the SAM with RRQ and RSE.
Results: Exploratory factor analysis resulted in the extraction of four components: 1- conflicting thoughts of self, 2- dichotomous view of self 3- fear of others’ judgment, and 4- preoccupation with self-worth. These components totally explained 63.8% of the variance. The reliability of the questionnaire was obtained 0.91 using Cronbach's alpha.
Conclusion: Results indicated desirable psychometric characteristics of the SAM in student populations. However, more research is required to ensure the applicability of the instrument in other populations.
