Methods: In this randomized controlled intervention trial, a total of 20 patients were ran- domly assigned to one of the control group or intervention group. The control group only received traditional rehabilitation. However, the intervention group received traditional rehabilitation and Cognitive Orientation to daily Occupational Performance (CO-OP), re- spectively (during 18 sessions, 45 min/day in both groups). Occupational therapy sessions were held three times a week for a six-week duration. Occupational performance and sa- tisfaction, anxiety, depression, and sleep quality were measured before the intervention and in weeks 2, 6, and 14 (follow-up) using Canadian Occupational Performance Measure, Beck Anxiety Inventory, Self-rating Depression Scale, and Pittsburgh Sleep Quality Index, respectively. Findings: The results of the present study show that there were signifcant changes in all the studied variables in the two groups. However, these changes (P 0.05) were not sta- tistically signifcant between these two groups. Conclusion: The results of this study show that occupation-based interventions are as ef- fective as traditional therapeutic interventions on improving the anxiety, depression, and sleep quality in patients with hand burn injuries. © 2022 Elsevier Ltd and ISBI.
