Craving among individuals with stimulant use disorder in residential social model-based treatment - Can exercise help?

Background: In a randomized controlled 8-week trial, we examined the efficacy of aerobic and resistance exercise in reducing craving for methamphetamine (MA) among individuals with MA-use disorder during residential treatment.

Methods: Individuals with MA use disorder (138) who were newly enrolled in residential treatment volunteered for random assignment to either an 8-week exercise intervention (EX) or health education control (HE), with both conditions meeting 3 times weekly; 3 dropped out of the trial, bringing the analysis sample to 135. The majority of participants were male (80%), and 48% were Latino/Hispanic.

Impact of an exercise intervention on methamphetamine use outcomes post-residential treatment care.

Background: We examined the efficacy of an 8-week exercise intervention on posttreatment methamphetamine (MA) use among MA-dependent individuals following residential treatment.

Methods: 135 individuals newly enrolled in treatment were randomly assigned to a structured 8-week exercise intervention or health education control group. Approximately 1 week after completion of the intervention, participants were discharged to the community.

The Impact of Exercise On Depression and Anxiety Symptoms Among Abstinent Methamphetamine-Dependent Individuals in A Residential Treatment Setting.

Background: This paper reports data from a study designed to determine the impact of an 8-week exercise program on depression and anxiety symptoms among newly abstinent methamphetamine (MA)-dependent individuals in residential treatment.

Methods: One hundred thirty-five MA-dependent individuals, newly enrolled in residential treatment, were randomly assigned to receive either a 3-times-per-week, 60-minute structured exercise program for 8 weeks (24 sessions) or an equivalent number of health education sessions. Using mixed-modeling repeated-measures regression, we examined changes in weekly total depression and anxiety scores as measured by the Beck Depression Inventory and Beck Anxiety Inventory over the 8-week study period.

Predictors of depression outcomes among abstinent methamphetamine-dependent individuals exposed to an exercise intervention.

Background And Objectives: This paper expands on a study investigating depression outcomes in response to an 8-week exercise intervention among methamphetamine (MA) dependent individuals in early recovery.

Methods: A total of 135 MA-dependent individuals enrolled in residential treatment were randomly assigned to either a structured exercise intervention or a structured health education control group. Both groups were similar in format: 60-minute sessions, offered three times a week over an 8-week study period.

Exercise training improves heart rate variability after methamphetamine dependency.

Purpose: Heart rate variability (HRV) reflects a healthy autonomic nervous system and is increased with physical training. Methamphetamine dependence (MD) causes autonomic dysfunction and diminished HRV. We compared recently abstinent methamphetamine-dependent participants with age-matched, drug-free controls (DF) and also investigated whether HRV can be improved with exercise training in the methamphetamine-dependent participants.

Duration effects in contingency management treatment of methamphetamine disorders.

The primary aim of this study was to determine whether different durations of contingency management (CM) in conjunction with psychosocial treatment produced different rates of abstinence among methamphetamine dependent individuals. Participants were randomized to one of the four 16-week treatment conditions: standard psychosocial treatment or psychosocial treatment plus one of the three durations of CM (one-month, two-month, or four-month). A total of 118 participants were randomized to the four treatment conditions.

Eight weeks of exercise training improves fitness measures in methamphetamine-dependent individuals in residential treatment.

Objectives: Physical exercise has been shown to benefit diverse medical and behavioral conditions. This study assesses the feasibility and efficacy of an 8-week endurance and resistance training program on fitness measures in individuals undergoing residential treatment for methamphetamine (MA) dependence.

Methods: A total of 39 MA-dependent individuals were randomized to 3 days/week of exercise training (ET, n = 15) or health education without training (equal attention [EA], n = 14) over 8 weeks.

Preference for gamma-hydroxybutyrate (GHB) in current users.

Gamma-hydroxybutyrate (GHB) is a drug with significant abuse potential. The present study aimed to assess the relative value of escalating doses of GHB to current GHB users via the Multiple Choice Procedure (MCP), and to validate that the dose rated highest with the MCP would be self-administered at a greater rate than placebo. Participants were 5 current GHB users who were not currently trying to stop using GHB.

A comparison of voucher exchanges between criminal justice involved and noninvolved participants enrolled in voucher-based contingency management drug abuse treatment programs.

This report compares requests for goods or services made by participants in two clinical trials of contingency management for the treatment of substance abuse. One trial was for participants involved with the criminal justice system and one was for participants who were not involved with the criminal justice system. In both trials, participants earned vouchers that could be exchanged for goods or services.

Relationship between Tridimensional Personality Questionnaire scores and clinic attendance among cocaine abusing, buprenorphine maintained outpatients.

With the recent approval of buprenorphine for the treatment of opiate dependence in the United States it has become important to develop an understanding of the factors that influence the likelihood of successful treatment outcomes when using buprenorphine. This study examined, in a convenience sample, the relationship between novelty-seeking behaviors, as determined by Cloninger's Tridimensional Personality Questionnaire (TPQ), and attendance variables during participation in a buprenorphine-based treatment program for 21 heroin-dependent cocaine users that took place in the late 1990s. Approximately two-thirds of the participants were male and primarily African-American.

Investigating the use of contingency management in the treatment of cocaine abuse among individuals with schizophrenia: a feasibility study.

This small-scale study was conducted to examine the feasibility of using voucher-based reinforcement therapy (VBRT) as a treatment modality for cocaine abuse among individuals with schizophrenia. Cocaine use was reduced in three individuals with a diagnosis of schizophrenia during a VBRT intervention. Interestingly, all of the abstinence occurred during the first half of the intervention.
