Brief Summary

The investigators are testing the efficacy of Smartphone-delivered cognitive behavioral therapy (CBT) treatment for body dysmorphic disorder (BDD). The investigators hypothesize that participants receiving app-CBT will have greater improvement in body dysmorphic disorder symptom severity than those in the waitlist condition at treatment endpoint (week 12).

Outcome Measures

Primary Outcomes (1)

  • Difference in BDD Severity (BDD-YBOCS) at the End of Treatment/Waitlist Period.

    The BDD Yale-Brown Obsessive Compulsive Scale (BDD-YBOCS) is the gold-standard, semi-structured clinician-administered assessment of BDD severity. It contains 12 items ranging from 0 to 4, which are summed to generate a total score (range = 0 to 48). Higher scores indicate more severe BDD symptoms. The BDD-YBOCS

    Week 0, Week 6, and Week 12

Secondary Outcomes (4)

  • Difference in Depression at the End of Treatment/Waitlist Period

    Week 0, Week 6, and Week 12

  • Difference in Delusionality at the End of Treatment/Waitlist Period

    Week 0, Week 6, and Week 12

  • Difference in Functional Impairment at the End of Treatment/Waitlist Period

    Week 0, Week 6, and Week 12

  • Difference in Quality of Life at the End of Treatment/Waitlist Period

    Week 0, Week 6, and Week 12

Device: Smartphone-delivered cognitive behavioral therapy (CBT) for body dysmorphic disorder (BDD)

12 Week Waitlist Control

OTHER

Device: Smartphone-delivered cognitive behavioral therapy (CBT) for body dysmorphic disorder (BDD)

Interventions

12-week Smartphone-delivered CBT for BDD. In-person cognitive behavioral therapy (CBT) is an empirically supported treatment for BDD. The app-delivered CBT in this project includes modules such as cognitive skills (e.g., cognitive restructuring, core belief work), behavioral skills (e.g., exposure with ritual prevention), and perceptual retraining/mindfulness skills.
