Individual Factors of CBT Underlying Success

Официальное название

Contributions of Self-Focused Attention to Early Warning Indicators of Cognitive Behavioral Therapy Non-Response

Обзор

The purpose of this study is to understand why some individuals respond fully to cognitive behavioral therapy and others do not, based on multiple sources of data such as neural, neurocognitive, clinical, and self-report data.

Подробное описание

The investigators are conducting this research to evaluate the reliability and construct validity of measures of self-focused attention (SFA) across neural, neurocognitive, and self-report levels of analysis as well as examine whether early changes in the SFA biomarker are associated with CBT non-response.

This will be looked at in a clinical population consisting of individuals with social anxiety disorder (SAD) and body dysmorphic disorder (BDD) compared to healthy volunteers. This study employs an open clinical trial for cognitive behavioral therapy with pre-, mid- and post-treatment neuroimaging scans, clinical interviews, neurocognitive, behavioral, and self-report assessments. Clinical participants will be invovled for 3.5 months and complete 12 CBT sessions and 4 fMRI scans. Control participants will not participate in CBT treatment and will complete 3 fMRI scans across a 3.5 month period. About 160 people will take part in this research study, all at the University of Washington (UW). This will include 110 clinical participants and 50 healthy control participants.
