Effects of Roy's Adaptation Model on Quality of Life in People with Opioid Abuse under Methadone Maintenance Treatment: A Randomized Trial.

Background: Opioid abuse is one of the most obvious problems in today's world and directly affects individuals' quality of life. The present study aimed to investigate the effects of Roy's adaptation model on the quality of life in people with opioid abuse under methadone maintenance treatment.

Methods: This randomized trial study was conducted in 2021 on 72 patients with opioid abuse under methadone maintenance treatment at the Center for Addiction Harm Reduction in Isfahan. The samples were randomly allocated into intervention (n=36) and control groups (n=36) based on the table of random numbers by computer. The intervention was conducted by implementing Roy's adaptation model in the intervention group. To analyze the data, paired t-test, independent sample t-test, chi-square test, and analysis of covariance were used.

Results: The mean ± standard deviation of the quality of life score in the intervention group (28.96±4.79) was significantly different than before the intervention (24.02±6.09) (P<0.001). At the same time, it was not significantly different in the control group. The mean ± standard deviation of the quality of life score in the intervention group (24.02±6.09) was not significantly different from the control group (20.55±8.53) before the intervention.

Conclusion: Roy's adaptation model had positive effects on the quality of life score in patients with opioid abuse. On the other hand, patients' quality of life indicates the effectiveness of methadone maintenance treatment. Therefore, it is suggested to use this model in nursing care programs.
