Abstract

Experiencing drug cravings is an aspect of substance use disorders that frequently compromises the recovery efforts of people who use drugs. Most treatment approaches that address drug cravings either involve cognitive strategies or medication. Few interventions directly address the physiological aspects of craving, such as increased heart rate. Previous research has demonstrated that slow-paced breathing may be effective in managing drug cravings by manipulating an individual's heart rate. The purpose of this paper is to describe a study protocol for an intervention that offers resonance frequency breathing training for managing cravings via a smartphone application (app). This trial is registered in ClinicalTrials.gov (Identifier: NCT05830773). The intervention focuses on persons in recovery from opioid use disorder who receive services from the Texas Health and Human Service Commission Recovery Support Services division. Participants will be trained to use Camera Heart Rate Variability (CHRV), a resonance frequency breathing app. The CHRV app measures heart rate and the volumetric variations of blood circulation. When experiencing stress, anxiety, or cravings, participants will use the app to practice breathing exercises. Participants (N = 60) will also complete surveys at baseline, 4 weeks, and 8 weeks; the survey questions, covers demographic characteristics, personal trauma history, substance use experience, and utilization of substance use treatment services. The surveys will also include psychosocial measures of craving, stress, and anxiety to allow the study team to assess changes between baseline and study completion. Participants who complete the full 8-week intervention will be invited to participate in a 30-minute interview about their experience with the app. Interviews will provide details on implementation outcomes, including acceptability, appropriateness, and feasibility. Many evidence-based interventions for opioid use require interpersonal communication with individuals in one's recovery network. However, individuals may be unable to engage others in their recovery network in the moments when they are experiencing cravings or stress- and anxiety-related triggers. Therefore, recovery support interventions that emphasize individual self-management of cravings, stress, and anxiety when they occur can empower individuals in recovery and enhance existing interventions.
