Reward Processing and Exposure Therapy
University of California, Los Angeles
Summary
The investigators are conducting a clinical trial of therapy for public speaking anxiety. There are many eligibility criteria, but the main ones are that participants need to be socially anxious and have public speaking anxiety. In this clinical trial, all participants will do exposure therapy. Before doing exposure therapy in the study, though, participants will be randomized to do one of two treatments: i) a positive mood treatment, which is designed to increase how positive people feel, and ii) a relaxation treatment, which is designed to help people feel more relaxed. The investigators are doing this study to see whether doing the positive mood treatment or relaxation treatment first will affect how well exposure therapy works.
Description
A substantial number of individuals do not achieve clinically significant symptom relief from exposure therapy, or they may experience return of fear following completion of exposure therapy. This clinical trial aims to intervene on one potential reason exposure therapy's success is mitigated: anhedonia. Anhedonia is characterized by physiological, behavioral, neural, and self-report deficits in reward processing - where reward processing includes anticipation of reward (positive experiences, such as social connection, food, personal achievement), engaging in effort for reward, feeling motivat…

Inclusion Criteria: * Diagnosis of social anxiety disorder from the Structural Clinical Interview for DSM 5. * Elevated fear of public speaking, defined as a score of \>= 66 (+1SD from the mean of population norms on a scale of 17-85) on the Public Speaking Anxiety Scale (PSAS; Bartholomay, E. M., \& Houlihan, D. D. (2016). Public Speaking Anxiety Scale: Preliminary psychometric data and scale validation. Personality and individual differences, 94, 211-215), which is a self-report scale measuring anxiety of public speaking. * Low reward processing, defined as a score of \<56 (less than the po…
Interventions
- BehavioralPositive Affect Treatment - Behavioral (PAT-B)
8 therapy sessions conducted individually with a therapist. Focuses on improving reward processing to increase positive emotional experience. Specific techniques include psychoeducation on mood cycle and positive emotions, mood monitoring, behavioral activation, and imaginal recounting and savoring of behavioral activation events. Intervention includes between-session practice.
- BehavioralRelaxation Treatment
8 therapy sessions conducted individually with a therapist. Focuses on mindfulness and relaxation skills. Specific techniques include mindfulness approaches from dialectical behavior therapy, diaphragmatic breathing, and progressive muscle relaxation. Intervention includes between-session practice.
- BehavioralExposure Therapy
8 therapy sessions conducted individually with a therapist using the inhibitory retrieval model of exposure therapy. Sessions are designed to include four exposures each (32 exposures total). Each exposure is a public speech delivered to an audience. Goal of this treatment is to reduce public speaking anxiety. Principles of exposure therapy that will be incorporated are maximizing prediction error, maintaining attention to the situation/stimuli that are perceived predictors of the feared outcome (e.g., social rejection), removing safety signals, variability, engaging in post-exposure rehearsal/consolidation, deepened extinction, and positive occasion setter extinction. Intervention does not include between-session practice.
