About this study

Official title: Smartphone Cognitive Behavioral Therapy for Body Dysmorphic Disorder: A Randomized, Waitlist-control Trial

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).

Read the detailed description

The primary aim of this study is to test the efficacy of a Smartphone-based cognitive behavioral therapy (CBT) treatment for adults with body dysmorphic disorder (BDD) recruited nationally. In a prior study (Clinical Trials Identifier # NCT03221738), the investigators developed and pilot-tested the feasibility, acceptability, and preliminary efficacy of a CBT for BDD app in an open pilot trial. The investigators are now further testing these outcomes in a randomized controlled trial. Eligible subjects (N= 64) will be randomly assigned to 12-weeks of Smartphone-delivered CBT for BDD either immediately, or after a 12-week long waiting period (50/50 chance).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

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

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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

    Measured: Week 0, Week 6, and Week 12

Secondary outcomes (4)
  1. Difference in Depression at the End of Treatment/Waitlist Period

    The self-report Quick Inventory of Depressive Symptomatology (QIDS-SR) is a measure of depressive symptoms consisting of 16 scale items with responses ranging from 0 to 3, including one suicide item (item #12). Total scores have a range from 0 to 27 with higher scores indicating greater depression severity. The measure is a well-validated, sensitive measure of symptom severity in depression.

    Measured: Week 0, Week 6, and Week 12

  2. Difference in Delusionality at the End of Treatment/Waitlist Period

    Delusionality was assessed using the Brown Assessment of Beliefs Scale (BABS). The BABS is a semi-structured, clinician-administered interview that assesses delusional thinking related to one's appearance concerns. It contains 7 items ranging from 0-4; the first six items are summed to generate a total score (range: 0-24). Higher scores indicate greater delusionality.

    Measured: Week 0, Week 6, and Week 12

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

    Functional impairment was measured using the Sheehan Disability Scale (SDS). The SDS is a self-rated, 3-item questionnaire that uses a Likert scale from 0 (not at all) to 10 (extremely) to assess impairment in occupational, social, and family domains. The 3 items are summed for a total score (range: 0-30), where higher scores indicate greater functional impairment.

    Measured: Week 0, Week 6, and Week 12

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

    Quality of life was assessed using The Quality of Life, Enjoyment, and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF). The Q-LES-Q-SF is a 16-item self-report measure of subjective quality of life, containing Likert items ranging from 1 (Very Poor) to 5 (Very Good). Total scores are presented as a percentage of the maximum value (i.e., ranging from 0 to 100), with higher scores indicating greater quality of life.

    Measured: Week 0, Week 6, and Week 12
