Reward Processing and Exposure Therapy for Social Anxiety Disorder
This study is for adults aged 18-60 who have social anxiety disorder, especially public speaking anxiety. It aims to see if improving positive mood or relaxation before exposure therapy (a treatment where you gradually face your fears) makes the exposure therapy work better. All participants will receive 8 sessions of exposure therapy. Before that, you'll be randomly assigned to either 8 sessions of Positive Affect Treatment - Behavioral (PAT-B), which focuses on increasing positive emotions, or 8 sessions of Relaxation Treatment, which teaches mindfulness and relaxation skills. Researchers will measure your public speaking anxiety and how you approach anxiety-provoking situations to see which approach is more effective.
- Study design
- This interventional study plans to enroll 94 participants. All participants will receive exposure therapy, but will be randomized to receive either Positive Affect Treatment - Behavioral or Relaxation Treatment beforehand.
- What's involved
- You would attend 8 therapy sessions for either PAT-B or Relaxation Treatment, followed by 8 sessions of Exposure Therapy. There will be assessments at the start, after each treatment phase, and at a 3-month follow-up.
- Compensation
- Not stated in the trial record.
- Follow-up
- You will be followed for 3 months after completing the exposure therapy.

What this trial measures
- Public Speaking Anxiety Scale (PSAS)Pre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24). Also Sessions 2, 4, 6, 8 of each therapy (corresponding to ~weeks 1, 2, 3, 4, 7, 8, 9, 10).
Self-reported public speaking anxiety symptom severity. This measure is a 17-item questionnaire using a 1-5 scale (1 = not at all, 3 = moderately, 5 = extremely) with sum scores ranging 17-83. Higher = worse.
- Behavioral Approach Task - AnxietyPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Self-reported anxiety during public speaking Behavioral Approach Task. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). The investigators will measure participants' anxiety throughout this task, including anxiety while anticipating the speech and delivering the speech. Anxiety will be measured "right now" on a 0-100 scale, where 0 = no anxiety, 50 = moderate, and 100 = extreme. Higher = worse.
- Behavioral Approach Task - Likelihood ExpectancyPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Self-reported likelihood that participant will be / was negatively socially evaluated during public speaking Behavioral Approach Task. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). The investigators will measure participants' expectation that they will be negatively socially evaluated by the audience during the public speech. The investigators will measure this in anticipation of the speech (likelihood that the participant will be negatively socially evaluated) and after completing the speech (likelihood that the participant was negatively socially evaluated). Likelihood expectancy will be measured on a 0-100 scale, where 0 = certain they will not negatively evaluate you, 50 = completely uncertain, and 100 = certain they will negatively evaluate you. Higher = worse.
- Behavioral Approach Task - Severity ExpectancyPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Self-reported belief that, if participant will be / was negatively socially evaluated during public speaking Behavioral Approach Task, how severe do they think the negative social evaluation will be / was. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). The investigators will measure participants' expectation that, if they are negatively socially evaluated by the audience during the public speech, how severe do they believe that severity will be / was. The investigators will measure this in anticipation of the speech (severity of negative social evaluation if it were to occur) and after completing the speech (severity of negative social evaluation if it did occur). Severity expectancy will be measured on a 0-100 scale, where 0 = not at all, 50 = moderate, and 100 = extreme. Higher = worse.
- Behavioral Approach Task - Like/Dislike of SpeechPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Self-reported liking/disliking of public speech. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). After completing the speech, participants will rate how much they liked or disliked giving their public speech (-10 = dislike very much, 0 = neutral, +10 = like very much). Higher = better.
- Behavioral Approach Task - Skin ConductancePre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Skin conductance during Behavioral Approach Task. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). Skin conductance is a physiological measure that will be analyzed during the speech anticipation period, where participants sit quietly for 2 minutes prior to giving their speech. The investigators will assess mean skin conductance level during this anticipation period minus their mean skin conductance level during a 2-minute baseline period prior to the speech task. Higher = worse.
- Behavioral Approach Task - Electrocardiography HF-HRVPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Electrocardiography during Behavioral Approach Task. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). Electrocardiography is a physiological measure that will be analyzed during the speech anticipation period, where participants sit quietly for 2 minutes prior to giving their speech. Using electrocardiography, the investigators will analyze high frequency heart rate variability (HF-HRV) during this anticipation period. Higher = better.
- Behavioral Approach Task - Electrocardiography RMSSD HRVPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Electrocardiography during Behavioral Approach Task. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). Electrocardiography is a physiological measure that will be analyzed during the speech anticipation period, where participants sit quietly for 2 minutes prior to giving their speech. Using electrocardiography, the investigators will analyze root mean square of successive differences (RMSSD) heart rate variability (HRV) during this anticipation period. Higher = better.
- Behavioral Approach Task - Electrocardiography LF/HF-HRVPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
Electrocardiography during Behavioral Approach Task. The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). Electrocardiography is a physiological measure that will be analyzed during the speech anticipation period, where participants sit quietly for 2 minutes prior to giving their speech. Using electrocardiography, the investigators will analyze low frequency divided by high frequency heart rate variability (LF/HF-HRV) during this anticipation period. Higher = worse.
- Behavioral Approach Task - Speech DurationPre Tx (week 0), Post Tx-1 (after PAT-B or Relaxation Treatment) (~week 6), Post Tx-2 (after Exposure Therapy) (~week 12), 3-Month Follow-Up (~week 24).
How long the participant delivers their speech (between 0 and 5 minutes). The Behavioral Approach Task is a task in which the participant gives a speech to a small audience (1-4 people) on a topic of the experimenter's choosing. One of four speech topics will be conducted (counterbalanced). Participants can stop their speech whenever they choose to do so (e.g., if feeling anxious). Speech duration is a behavioral measure. Higher = better.
