Wellness, Alcohol, Vitals, and Emotions

Description

This study will assess the changes in self-regulation as measured through heart rate variability (HRV), that occur during the course of an 8-week mindfulness-based relapse prevention (MBRP) treatment. The investigators will use a single-group design to test the effects of MBRP on resting, reactivity, and recovery HRV. Additionally, the study will test whether changes in HRV that occur week over week during treatment can affect drinking behaviors in daily life. Individuals (n=120) who meet criteria for moderate to severe alcohol use disorder will be mailed small HRV sensors to be worn before, during, and after each MBRP group. Participants will answer questions about their functioning, alcohol use, addiction cycle domains, and mood at baseline, and at follow-up months 3 and 6.

MBRP groups will be delivered at the same time each week for 8 consecutive weeks, known as the treatment period. During the treatment period, participants will self-attach their sensors before each MBRP group, watch a brief presentation to collect resting HRV, complete their group, and watch a brief presentation after each group. During the treatment period, participants will also answer questions about their drinking, functioning, and mood 3 times a day.
