Trial Outcomes & Findings for Cognitive-Behavioral Therapy and Supportive Psychotherapy for Body Dysmorphic Disorder (NCT NCT01453439)
NCT ID: NCT01453439
Last Updated: 2020-07-15
Results Overview
The Yale-Brown Obsessive Compulsive Scale Modified for BDD (BDD-YBOCS) is a 12-item, semi-structured, clinician-administered measure of BDD symptom severity. The scale's items are summed to yield a total score with a range from 0 to 48, with higher scores indicating more severe BDD symptoms. Treatment effects on BDD symptom severity were analyzed separately for the treatment period (i.e., weeks 0-24) and the follow-up period (i.e., weeks 24 to 50).

Cognitive Behavior Therapy (CBT) is considered the psychosocial treatment of choice for BDD. It is a time-limited treatment that includes cognitive restructuring, mindfulness/attention retraining, exposure, and response prevention, specifically tailored for BDD. CBT is the only fully developed psychosocial treatment for BDD.

PRIMARY outcome
Timeframe: Change in BDD-YBOCS from baseline (week 0) to post-treatment (week 24), assessed every 4 weeks. Followup phase data was measured at week 37 and week 50.Population: Intent to treat analysis on 120 subjects randomized to either CBT vs SPT. Some of the assessments visits were missed due to patient cancellations or study dropouts. The exact numbers analyzed are as specified below.

Timeframe: Measured every 4 weeks during treatment, and at the 3-(wk 37) and 6-month(wk 50) follow-up visitsPopulation: Intent to treat analysis on 120 subjects randomized to either CBT vs SPT. Some of the assessments visits were missed due to patient cancellations or study dropouts. The exact numbers analyzed are as specified below.
The Brown Assessment of Beliefs Scale (BABS) is a 7-item, semi-structured, clinician-administered measure that was used to assess insight regarding BDD-related beliefs (e.g., "I look deformed"). The first six items of the BABS were summed to obtain a total score ranging from 0 to 24, with higher scores reflecting poorer insight. Treatment effects on BABS score were analyzed separately for the treatment period (i.e., weeks 0-24) and the follow-up period (i.e., weeks 24 to 50).

SECONDARY outcome
Timeframe: Measured every week during treatment, but analysis was performed only on BDI-II assessments close to assessment visits; wk 0, 4, 8, 12, 16, 20 and 24. Followup phase data was measured at week 37 and week 50.Population: Intent to treat analysis on 120 subjects randomized to either CBT vs SPT. Some of the assessments visits were missed due to patient cancellations or study dropouts. The exact numbers analyzed are as specified below.
The Beck Depression Inventory-Second Edition (BDI-II) is a widely used 21-item self-report scale that assesses the severity of depressive symptoms during the past 2 weeks. Total scale scores range from 0 to 63, with higher scores indicating greater symptom severity. Treatment effects on depression were analyzed separately for the treatment period (i.e., weeks 0-24) and the follow-up period (i.e., weeks 24 to 50).

The Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LESQ-SF) is a 16-item, self-report questionnaire that assesses life satisfaction over the past week. Questions 1-14 are then summed to a total score, and the total score is reported as a percentage maximum possible, such that the % score range is 0% to 100%, with higher scores indicating greater quality of life. Treatment effects on life satisfaction were analyzed separately for the treatment period (i.e., weeks 0-24) and the follow-up period (i.e., weeks 24 to 50).

The Treatment Credibility/Expectancy Rating scale is a 4-item self-report questionnaire that assesses patients' judgments about the credibility of the treatment rationale, expectancy of change, and treatment acceptability. Treatment credibility is based on the mean score of the first three items, which are measured on 10-point Likert scales, so that mean scores range from 1 (lowest/worst) to 10 (highest/most). Treatment credibility was assessed at the baseline assessment (before treatment assignment) and after 1 month of treatment when patients are more familiar with the treatment protocol and rationale.

The Sheehan Disability Scale (SDS) is a 5-item self-report measure of functional impairment/disability. Items 1-3 (disability in work, social life/leisure, and family life/home responsibilities, respectively) are scored on Likert-scales that range from 0 (not at all) to 10 (extreme). The three items are then summed to yield an SDS total score, ranging from 0 (unimpaired) to 30 (highly impaired). Treatment effects on functional impairment were analyzed separately for the treatment period (i.e., weeks 0-24) and the follow-up period (i.e., weeks 24 to 50).

The Treatment Credibility/Expectancy Rating scale is a 4-item self-report questionnaire that assesses patients' judgments about the credibility of the treatment rationale, expectancy of change, and treatment acceptability. Treatment expectancy is a single item rating of "By the end of therapy, how much improvement in your anxiety do you think will occur?", rated on a scale from 0% to 100%.
