Introduction: Deliberate self-harm (DSH) represents a significant mental health concern, particularly among individuals diagnosed with psychiatric disorders. Understanding the prevalence and patterns of DSH across different psychiatric disorders is crucial for developing targeted interventions and prevention strategies. This study aims to explore the distribution of deliberate self-harm among individuals with psychiatric disorders. Methods: This descriptive cross-sectional study was carried out at Department of psychiatry, Sheikh Hasina Medical college, Jamalpur, Bangladesh during the period from July 2013 to June 2014. According to the inclusion criteria, 100 cases of patients with different psychiatric disorders were included in the study. Study subjects were selected by purposive sampling technique. Data were gathered using a semi-structured questionnaire that included all pertinent information about intentional self-harm, as well as psychiatric problems. The patient's informed consent was obtained. Data analysis was done by using a statistical package for social science (SPSS) 12 version. Result: The study included 100 subjects with psychiatric disorders, predominantly aged 20-39 years (77.0%). Females represented a higher proportion (61.0%) compared to males (39.0%), and most participants (90.0%) had no family history of mental illness. Deliberate self-harm (DSH) was most prevalent in patients with Major Depressive Disorder (62.5%) and Schizophrenia (60.0%). Other disorders showed lower rates of DSH: Anxiety Disorders (27.0%), Bipolar Disorder (40.0%), Adjustment Disorder (20.0%), and PTSD (20.0%). No patients with Personality Disorders engaged in DSH. Conclusion: The findings from this study emphasize the critical link between psychiatric disorders and deliberate self-harm, with the highest prevalence noted among those diagnosed with Major Depressive Disorder and Schizophrenia. The results also reveal that younger adults, particularly within the 20-39 age ran
