Objective:
Hoarding disorder (HD) is difficult to treat. In an effort to increase efficacy and engagement in cognitive-behavioral therapy (CBT), we developed and evaluated a novel intervention comprising group CBT combined with between-session Internet-based clinician support for people with HD.
Method:
Twenty participants with HD received group CBT combined with an Internet-support system enabling therapist-participant communication between group sessions.
Results:
The treatment was associated with a significant reduction on the Saving Inventory-Revised (SI-R) and a large effect size (Cohen's d = 1.57) was found at posttreatment. Treatment gains were maintained at the 3-month follow-up. Group attendance was high and no participants dropped out from treatment prematurely. Between-session motivational support from the therapist was most frequently mentioned as the main strength of the system.
Conclusion:
The results of this study support adding Internet-based clinician support to group CBT for HD to increase treatment adherence and, potentially, improve the overall efficacy of CBT.
