First, the occupational therapists in the two groups were not completely blinded to the nature of the intervention. Sec- ond, our findings were based on a relatively small number of patients, all of whom were women. Third, so far no follow-up study has been conducted to corroborate the findings. A future follow-up study should include a larger sample and should include men as well. Moreover, this study only evaluated tasks performed by patients in the intervention group.
Future work should put greater emphasis on comparison with the control group, and assess results for different types of tasks and activities. In addi- tion, as noted earlier, our study only involved six inter- vention sessions. Therefore, there is a need to conduct a longer study involving more sessions to fully assess the ability of this approach to positively affect depressive symptoms and cognitive functioning.
