Effects of Client-Centered Occupational Therapy Intervention in Older Adults With Depression: A Randomized Controlled Trial.

Only 30 people took part, all from a single centre in South Korea, so the findings may not hold for other older adults with depression. The comparison group was not untreated: they received case management plus gymnastics twice a week, and their depression improved too. The study therefore shows extra benefit over that programme, not over no treatment. No follow-up assessment was carried out, so it is unknown whether any of the improvements lasted after the sessions stopped. Anxiety improved within the occupational therapy group but was not significantly better than the control group, yet the conclusion lists anxiety among the interventions that were effective. The activities participants chose were largely sedentary, which the authors say may explain why daily living skills did not improve. The daily living and community participation measures used were Korean tools rather than internationally used ones. In this age group physical illness at the time of assessment could not be ruled out as an influence on the results. Only significance tests are reported, with no mean scores or effect sizes, so how large the benefits were is unclear.

The conclusion says the programme reduced anxiety, but anxiety only improved inside the occupational therapy group and was not significantly better than the control group. Also, the control group received active treatment twice a week and their depression improved too, so do not read the depression and stress results as showing occupational therapy beats no treatment.
