ACT for Reducing Attrition and/or Improving Adherence
Given that therapy can only be effective when clients are attending sessions and are actively engaging with the treatment, it is crucial to determine ways to increase adherence and reduce attrition. The following is a list of studies that determine the effectiveness of ACT in reducing drop out and/or increasing adherence or engagement in treatment (list gathered by Brandon Gaudiano).

- Mike Twohig has a grant from the International OCD Foundation (IOCDF) to compare ACT+Exposure and Response Prevention (ERP) versus ERP alone to test whether ACT promotes better engagement in exposures (in progress).
- Maria Karekla’s dissertation showed that those receiving ACT for panic disorder had a different pattern of attrition compared to those receiving Panic Control Therapy (where most drop outs occurred following initiation of exposure).
