This study was performed to examine different types of self-mutilation in patients suffering from psychiatric disorders and its relation with the type of illness among patients attending to Lavasani Hospital in ۲۰۱۴-۱۵. Methods: This study is a cross-sectional observation. Forty-two patients suffering from psychiatric illnesses who had performed self-mutilation entered the study. The prevalence of the type of self-mutilation, the used device, and its relation with the type of mental disorder was analyzed. Results: The Results showed that ۹۰.۵% of patients used sharp objects, ۴.۸% used fire, ۲.۴% used rocks, and ۲.۴% used other devices for self-mutilation. ۷۶.۲% of patients injured the organs, ۱۹% injured the head and neck, ۲۴% injured the body, and ۲.۴% injured the stomach area. Age and sex did not have a direct correlation with the place and device used (P>۰.۰۵), but type of disorder did show a significant relationship with the place and device used (P=۰.۰۰۱). Conclusion: It is concluded that self-mutilation in mental patients is done mainly using sharp objects in the organs.
