PG - 694-701 LID - 10.1111/eip.12368 [doi] AB - AIM: Anxiety is a common presenting concern for individuals at clinical high risk (CHR) for psychosis. Treatment for CHR is still in the early stages and has focused on transition to psychosis and positive symptom reduction, but little is known about what may be effective in reducing anxiety for these young people. One treatment that may be effective for anxiety is heart rate variability (HRV) biofeedback. The aim of this study was to test the efficacy and feasibility of using HRV biofeedback to reduce anxiety and distress in those at CHR. METHODS: Twenty participants who met minimum scores for anxiety and distress completed 4 weeks of an HRV biofeedback intervention and received pre- and post-intervention assessments. Repeated measures were used to examine changes in scores over time. RESULTS: There was a significant decrease in impaired ability to tolerate normal stressors (P
