A pilot randomized controlled trial of aquatic-based activities in a group occupational therapy program for adults living with serious mental illness in Spain

Abstract

Although aquatic-based interventions are increasingly used in the psychiatric rehabilitation services, the effects of this type of community program as an adjuvant therapy for psychosocial problems of people with serious mental illness (SMI) have been under-explored. This research evaluated the feasibility and outcomes of an occupational therapy program consisting of aquatic-based activities (AA-OT program) in the community in Spain. This study is the first randomized controlled trial (RCT) on this topic. This pilot trial was conducted with a sample of 16 adults with SMI who were randomly allocated to the AA-OT program plus treatment as usual or treatment as usual alone (eight in each group). The AA-OT program included activation of daily living skills, warm-up, group activities/tasks, and relaxation. It consisted of two sessions per week over 12 weeks. Outcomes were evaluated at week 0 and 12. A total of 14 participants (87.5%) completed the trial. No adverse events or side-effects were noted. Comparisons between the two groups on change scores showed that participants in the intervention group showed significant improvements in several outcome measures: psychosocial problems (HoNOS), two health-related quality of life scales (SF-36: Physical Functioning and Mental Health), and performance of social activities (Activity and Social Relations scale). Satisfaction with the program was high. In conclusion, the results support the feasibility and potential benefits of this occupational therapy program. 12 weeks of aquatic-based activities in a group intervention may enhance the outcomes of psychiatric rehabilitation improving the severity of psychosocial problems, patient-reported health status, and social relations. This community-based program may be beneficial as a non-pharmacologic method in the illness management and recovery of people with SMI. The findings from this pilot trial need to be confirmed in a large, fully-powered RCT.
