Background and Objective Insomnia is highly prevalent in psychiatric disorders, yet its patterns and predictors vary across diagnoses and cultural contexts. This study examined the prevalence and associations of insomnia in adult psychiatric patients in an outpatient setting. Methods A cross-sectional study was conducted among 380 adult psychiatric patients at a tertiary hospital. Insomnia was assessed using the Structured Clinical Interview for DSM-5 Sleep Disorders–Revised. Sociodemographic, clinical, and lifestyle variables were assessed, and logistic regression analyses were used to identify predictors of insomnia. Results The prevalence of insomnia was 44.2%, with the highest rates observed in trauma-and stressor-related disorders, followed by depressive disorders. Schizophrenia spectrum disorders, obsessive compulsive disorder, and conversion disorder showed significantly lower odds of insomnia compared to depressive disorders. Key predictors of insomnia included lower educational level (0–5 years: adjusted odds ratio [aOR]=5.60, p=0.015), low socioeconomic status (aOR=6.57, p=0.044), comorbid physical illness (aOR=3.81, p=0.005), and prolonged screen time (aOR=8.17, p<0.001). Conclusions Insomnia affects nearly half of adult psychiatric patients, with considerable variation across diagnostic categories. These findings underscore the need for targeted sleep assessment and interventions within psychiatric services, especially in low resource settings.
