Brief Summary

90 sedentary adults with a primary anxiety disorder and high anxiety sensitivity will be randomized to either 8 weeks of 1) low intensity exercise, or 2) flexible titration to high intensity exercise (HIE). Blinded, validated clinician-rated and patient-rated outcomes will be assessed over treatment and at 1- and 3-month follow-up. To better understand what mechanisms influence decisions to exercise in the real-world, we will use of heart rate (HR) as an objective mechanistic target for exercise intensity, examine changes in valuation of exercise through a neuroeconomics task, examine changes in interoceptive sensitivity with a heartbeat detection task, and integrate of ecological momentary assessment (EMA) to measure effects of immediate changes in mood with exercise on anxiety outcomes and adherence.

Outcome Measures

Primary Outcomes (2)

  • Change in Anxiety Sensitivity Index-3 (ASI-3) score

    The ASI-3 is an 18-item measure of fear of anxiety sensations with three subscales (physical, cognitive, social concerns). The total score ranges from 0 (lowest anxiety sensitivity) to 72 (highest anxiety sensitivity).

    Baseline, Week 8

  • Change in Clinical Global Impressions/Severity Scale score

    A validated Clinical Global Impressions/Severity Scale (CGI) anchored for anxiety disorders measures overall functioning and clinical improvement. CGI-S is rated from 1 (least disordered) to 7 (most disordered).Scores of 1 or 2 on the CGI-I at post-treatment will represent significant response.

    Baseline, Week 8

Secondary Outcomes (15)

  • Engagement

    Week 12, Week 20

  • Adherence

    Week 8, Week 12, Week 20

  • Structured Interview Guide for the Hamilton Anxiety Scale (SIGH-A) Score

    Week 1, Week 4, Week 8, Week 12, Week 20

  • Work and Social Adjustment Scale (WSAS) Score

    Week 1, Week 4, Week 8, Week 12, Week 20

  • Overall Anxiety Severity and Impairment Scale (OASIS) Score

    Week 1, Week 4, Week 8, Week 12, Week 20

  • +10 more secondary outcomes

Interventions

All participants will receive psychoeducation regarding the rationale for using exercise as a strategy to create immediate changes in mood and anxiety. Participants will be instructed in basic motivational principles (e.g., breaking up goals into smaller parts, using rewards) based on information in Exercise for Mood and Anxiety. Participants will begin at low intensity with the goal of titrating to high intensity by 2 weeks prior to the end of trial (Week 6). If a participant achieves at least 70% of the duration goal at the target heart rate, he/she will be titrated to the next dose level (moderate intensity). This will continue until high intensity exercise is achieved. Prescription is based on heart rate reserve((maximum heart rate \[220-age\] - resting heart rate)\*intensity percent - resting heart rate. Intensity percent lower/upper limits for moderate intensity are 40-59% and for high intensity are 60-84%.

All participants will receive psychoeducation regarding the rationale for using exercise as a strategy to create immediate changes in mood and anxiety. Participants will be instructed in basic motivational principles (e.g., breaking up goals into smaller parts, using rewards) based on information in Exercise for Mood and Anxiety. Prescription is based on heart rate reserve ((maximum heart rate \[220-age\] - resting heart rate)\*30-39% (lower/upper limit of zone) - resting heart rate.
