Animal-assisted therapy on happiness and life quality of chronic psychiatric patients living in psychiatric residential care homes: a randomized controlled study

BACKGROUND: Psychiatric patients who live in psychiatric residential care homes may often feel a loss of autonomy, decision making, and participation in social activities. They usually have few or no visitors and also do not have any purpose for living. Animals may increase the happiness and quality of life of psychiatric patients. This study aimed to evaluate the effects of Animal-Assisted Therapy (AAT) on happiness and quality of life of chronic psychiatric patients living in psychiatric residential care homes in Tehran, Iran. METHODS: This randomized controlled trial was conducted with 70 males with a chronic psychiatric disorder who were living in psychiatric residential care homes in Tehran, Iran, in 2016. The patients were randomly selected and divided into animal therapy intervention group and control group. Patients in the intervention group received animal-therapy with a bird for eight weeks. Patients in the control group received no intervention. The Oxford Happiness Inventory evaluated all patients pre and post-intervention. To evaluate life quality, the Wisconsin Quality of Life Index was used. Data were statically analyzed using SPSS Ver.19.0. ANCOVA with pretest statistical control. The significance level was set as p < 0.05. RESULTS: The mean age in both control and intervention groups were 47.12 and 45.82 years, and the mean age of illness onset for both control and intervention groups was 18.94 and 16.83 years, respectively. The result of this study showed that happiness in the intervention group had significantly increased (p < 0.001). The results also showed that the quality of life in four sub-domains increased significantly. CONCLUSION: To bring happiness to chronic psychiatric patients living in psychiatric residential care homes is essential and may result in returning them to society and healthy life. The results of this study showed that AAT was helpful for chronic psychiatric patients living in psychiatric residential care homes and not only made them happy but also increased their quality of life.
