Aims: Obsessive-Compulsive Disorder (OCD) is one of the severe psychological health problems imposing considerable social and economic costs on society. OCD debilitating symptoms can disrupt interpersonal relations, job performance, and life quality. The purpose of this study is to investigate the mediating role of alexithymia in the relationship between coping strategies and personality traits with OCD. Methods & Materials: This is a descriptive correlational study. The study population consists of all people with OCD referred to psychiatric clinics in Kerman City, Iran, during 2018-2019. Of this population, 200 patients were selected using a convenience sampling method. Research instruments included the ways of coping questionnaire, NEO five-factor personality inventory, Toronto alexithymia scale, and Maudsley obsessive-compulsive test. The obtained data were analyzed using the Pearson correlation test and simultaneous and hierarchical regression in SPSS v. 23. Findings: Personality traits had a negative significant correlation with alexithymia (r=0.523, P<0.000) and OCD (r=0.253, P<0.000). Alexithymia had a significant positive correlation with OCD (r=0.272, P<0.000). There was no correlation between problem-focused coping and alexithymia (r=-0.045, P<0.531). There was a positive correlation between emotion-focused coping and OCD (r=0.198, P<0.000). The fit indices indicated a good fit of the proposed model (P<0.005). Conclusion: Alexithymia, as a mediator of the relationship between coping styles and personality traits with OCD, plays an essential role in improving the psychological health of people with OCD.
