Depression in people with intellectual disability : an evaluation of a staff-administered treatment program

The prevalence of co-morbid depression in people with intellectual disability (ID) provides a strong rationale for the early identification and treatment of individuals at risk. The aim of this study was to evaluate a staff-administered group CBT program for the treatment of depression in people with mild ID. A sample of 13 staff employed at two community-based disability agencies were trained to deliver the program to 47 individuals with mild ID and symptoms of depression. A wait list control group comprised of 27 individuals subsequently completed the program. Compared to the control group, individuals who had participated in the treatment program showed lower depression scores, and fewer automatic negative thoughts. Furthermore, these changes were maintained at a 3-month follow-up. The results indicate that staff can be trained to deliver a CBT program within community settings that is effective in the reduction of depression symptomatology in people with mild ID.
