Objective: Alcohol use disorder is associated with compulsive drinking and impaired self-control, often leading to poor sleep quality. This study aimed to assess the effect of metacognitive-based training on sleep quality in persons with alcohol use disorder. Methods: A quasi-experimental design was used with 30 male patients aged 25–45 years with alcohol use disorder and poor sleep quality, recruited from Recovery Home Foundation, Chennai. They were divided into control (conventional occupational therapy) and experimental (metacognitive-based training) groups. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) before and after the 12-week intervention. Data were analyzed using paired and independent t-tests. Results: The results showed a significant improvement in sleep quality in the experimental group compared to the control group (mean PSQI score: control 8.53 vs. experimental 4.87; p<0.001). Conclusion: The study concluded that metacognitive-based training was effective in improving sleep quality among male patients with alcohol use disorder.
