Background: The current study describes the development and evaluation of group treatment programme for people with mild/moderate intellectual disability (ID).
Methods: A total of 34 participants (16 males, 18 females) completed the treatment programme and 15 participants (six males, nine females) comprised a control group.
Results: Compared to the control group, the intervention group showed an improvement in levels of depression, positive feelings about the self, and lower levels of automatic negative thoughts after the intervention. These changes were maintained at 3-month follow-up.
Conclusions: These results demonstrate that intervention programmes are effective for the treatment of depression among people with ID.
