Exercise: Addressing Stress in Relapse Prevention for Substance Use Disorders

Relapse contributes significantly to the chronicity of substance use disorders, one of the most costly medical/mental health problems facing our nation. The incorporation of exercise into relapse prevention efforts will address stress, a critical factor in relapse, provide other health benefits, and improve overall quality of life. Combined, these changes will reduce the risk of relapse to substance use while also lessening the burden of this psychiatric disorder upon society

Study Overview

• Status: Completed
• Conditions: Substance Use Disorders
• Intervention / Treatment: Behavioral: Standard Aftercare Treatment; Behavioral: Motivational enhancement therapy (MET); Behavioral: Contingency management

Detailed Description

About half of all individuals who receive treatment for substance use disorders (SUD) relapse within a year. Stress and an individual's biological response to it are significant predictors of relapse. Thus, interventions that decrease stress and normalize an individual's biological response to stress are desperately needed. Exercise decreases stress and improves the body's regulation of stress. The proposed project will utilize exercise as a novel relapse prevention intervention with individuals who have recently completed inpatient SUD treatment. This project will evaluate the efficacy of a motivational intervention for exercise in a randomized clinical trial of 150 SUD patients beginning Aftercare treatment at the VA St. Louis Health Care System. Participants will be randomized to one of two interventions: (1) standard care (SC), or (2) standard care plus a motivational intervention targeting exercise that lasts for six months. Participants are followed every three months for one year. Results from this study will advance exercise as a new strategy for enhancing stress regulation and prevention of relapse in SUD populations.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Standard Aftercare Treatment; Standard aftercare treatment consists of once per week group counseling for six months. Aftercare includes the following topics: substance use, high-risk situations, coping and life skills training, focus groups for depression and anxiety, and AIDS education.	Behavioral: Standard Aftercare Treatment; Aftercare includes the following topics: substance use, high-risk situations, coping and life skills training, focus groups for depression and anxiety, and AIDS education.
Experimental: Standard Aftercare Treatment + Exercise Intervention; In addition to attending standard aftercare treatment, participants will receive three 50-minute motivational enhancement therapy sessions focused on exercise, plus 24 weekly contingency management sessions for exercise.	Behavioral: Standard Aftercare Treatment; Aftercare includes the following topics: substance use, high-risk situations, coping and life skills training, focus groups for depression and anxiety, and AIDS education.; Behavioral: Motivational enhancement therapy (MET); MET is a client-centered, directive method of enhancing intrinsic motivation for change by exploring and resolving ambivalence. In this intervention MET will focus on exercise.; Behavioral: Contingency management; Contingency management is a behavioral treatment that utilizes extrinsic motivation by offering individuals tangible rewards such as prizes for completion of specific target behaviors. The target behavior in this study is exercise.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in substance use (relapse)	Relapse is assessed during the duration of the study and is a time to event variable so it will be assess over time. Relapse is defined as drinking alcohol in excess of the National Institute on Alcohol Abuse and Alcohol (NIAAA) at-risk guidelines.	At baseline and every three months for one year.
Change in moderate to vigorous physical activity	Moderate to vigorous physical activity frequency, duration and intensity will be assessed over time to examine changes in response to the intervention. Frequency is defined as how often and individual engages in moderate to vigorous physical activity. Duration is the amount of time (minutes) per episode that individual engages in moderate to vigorous physical activity. Intensity is defined two ways: (1) self-report rating of intensity and (2) metabolic equivalent of the moderate to vigorous physical activity.	At baseline and every three months for one year.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in stress reactivity over time.	Stress reactivity is assess via a standardized psychosocial stressor paradigm that induces stress. Stress is assessed via salivary cortisol and self-report of stress.	At baseline and two additional times over one year.
