Enhancing Substance Use Disorder Recovery through Integrated Physical Activity and Behavioral Interventions: A Comprehensive Approach to Treatment and Prevention

The global issue of substance abuse demands ongoing initiatives aligned with the United Nations Sustainable Development Goals. With drug use remaining prevalent worldwide, interventions are critical to addressing the associated health challenges and societal implications. Exercise and physical activities have emerged as integral components of substance use disorder (SUD) treatment, offering promising avenues for prevention, intervention, and recovery. Recent research underscores the efficacy of exercise in reducing substance cravings, promoting abstinence, and improving overall well-being. However, integrating exercise into SUD recovery programs presents challenges such as dropout rates and cultural considerations. This paper synthesizes existing literature on exercise integration into SUD recovery, highlighting strategies for enhancing treatment outcomes and addressing barriers to exercise adherence. Drawing on cognitive-behavioral therapy, experiential learning, motivational interviewing, and goal-setting techniques, the holistic approach outlined in this paper aims to empower individuals both mentally and physically, fostering resilience and supporting long-term recovery. In conclusion, new initiatives need to be taken by advocating for inclusive policies, promoting community engagement, and fostering collaborations across sectors. By doing so, stakeholders can optimize the effectiveness of exercise programs and contribute to sustainable rehabilitation efforts for individuals with SUD.

Quality of Life and Use of Complementary and Alternative Medicines among Narcotics Anonymous Patients: A Cross-Sectional Study in Southeast Iran

Background

Addiction, a chronic and recurrent disorder, is associated with lasting changes in the brain and can significantly affect the quality of life of people. Complementary and alternative medicine (CAM) along with modern medical treatments can improve the quality of life of individuals. This study aimed to investigate the relationship between the use of complementary and alternative medicines (CAMs) and quality of life in narcotics anonymous patients.

Methods

This cross-sectional study was performed on 189 narcotics anonymous patients in southeastern Iran. Using questionnaires such as the demographic information, the World Health Organization Quality of Life-BREF (WHOQOL-BREF), CAM, and satisfaction with the use of CAM, the researcher was able to compile a comprehensive picture of the population.

Results

The mean score of overall quality of life and general health was 64.02 ± 23.32. Overall, 66.1 percent (n = 125) of the participants reported using at least one type of CAM in the previous year. Last year, 25.9% of participants used at least one kind of CAM, 22.8% used two types of CAM, 7.9% used three types of CAM, and 4.8% used four to five types of CAM. Thirty-nine point seven percent of them reported using prayer, 36.5% reported using medicinal herbs, 15.3% of participants reported using massage, 14.3% of participants reported using dietary supplements, 12.2% reported using wet cupping, and 8.5% reported using meditation. There were no significant differences in physical, psychological, environmental, and overall quality of life between CAM users and non-CAM users. The prayer users had significantly higher scores in terms of social relationships, environment, and overall quality of life than nonprayer users. Employed participants and opium users had significantly higher overall quality of life than others.

Conclusion

Although there was no difference in quality of life between CAM and non-CAM users, the present study showed that prayer and medicinal herbs were the most commonly used methods among narcotics anonymous patients. However, prayer and religious beliefs were successful in improving the quality of life of these individuals. Physicians and other healthcare providers must advise patients with addiction to use different CAMs in order to improve their quality of life and quit narcotics. Future in-depth studies could help these patients use CAMs and improve their quality of life.

Effects of 8 months of high-intensity interval training on physical fitness and health-related quality of life in substance use disorder

Objective

This study aimed to investigate the effect of 8 months of high-intensity interval training (HIIT) on physical fitness and health-related quality of life in substance use disorder.

Methods

Sixty substance use disorder were randomly assigned to either the HIIT group or the control group according to a random sampling method. The HIIT group received 8 months of four 60-min sessions per week under supervision. Weight, waist circumference, body fat percentage, heart rate, blood pressure, VO2max, reaction time, grip strength, standing on one foot with eyes closed, sitting forward flexion, and quadrant jumping, standing on one foot with eyes closed, the number of push-ups, quality of life (SF-36) score, and craving (VAS) scored were monitored in the HIIT and control groups at baseline, 4 months, and 8 months. SPSS 22.0 was used to conduct repeated measurement analysis of variance and Pearson correlation analysis on the collected subject data.

Results

Compared with baseline, weight (p < 0.001), waist circumference (p < 0.001), body fat percentage (p < 0.001), heart rate (p < 0.05), Systolic blood pressure (p < 0.01), systolic blood pressure (p < 0.05), reaction time (p < 0.001),PSQI (p < 0.001), Total cholesterol (p < 0.001), Triglyceride (p < 0.001), Blood sugar (p < 0.001) and VAS score (p < 0.001) were significantly decreased after 8 months of exercise intervention. Contrastingly, VO2max (p < 0.05), grip strength (p < 0.05), eyes closed and one foot Standing (p < 0.001), sitting forward flexion (p < 0.001), quadrant jumping (p < 0.001), push-ups (p < 0.001), PCS (p < 0.001), and MCS (p < 0.001) were significantly increased. VO2max was significantly negatively correlated with VAS (r = -0.434, p < 0.001), and significantly positively correlated with PCS (r = 0.425, p < 0.001). There was a positive correlation between standing on one foot with closed eyes and MCS (r = 0.283, p < 0.05).

Conclusion

Eight months of HIIT can comprehensively improve the physical health level and health-related quality of life of men with substance use disorders, reduce the desire for drugs, and lay the foundation for better starting a happy life.

Reduction in Substance-Related Composite Harm Scores Through Street Soccer

Introduction Street soccer makes the sport accessible to people affected by homelessness or precarious housing. There is overwhelming evidence that exercise improves physical and mental health. In addition, sport facilitates positive peer pressure that leads to beneficial life changes. Method To examine participants' accounts of the effects of street soccer in a sample of socially disadvantaged players from Western Canada, we collected 73 cross-sectional self-reports of life changes via a questionnaire. The questionnaire included questions on social, mental, and physical health, including substance use. This allowed the calculation of a modified composite harm score. Results Participants reported improved physical (46% of participants) and mental (43% of participants) health, reduced cigarette (50% of smokers), alcohol (45% of users), cannabis (42% of users), and other non-prescribed drug use, increased number of friends (88% of participants), improved housing (60% of participants), increased income (19% of participants), increased community medical supports (40% of participants), and decreased conflicts with police (47% of those with prior recent conflict). Perceived reductions in substance use were supported by significant changes in composite harm score. Conclusion Street soccer appears to promote improved physical, mental, and social health among people affected by homelessness or precarious housing, with reduction in substance use likely to be a key factor. This work builds upon past qualitative research showing the benefits of street soccer and supports future research which may help elucidate the mechanisms by which street soccer has beneficial effects.

Characteristics and impact of physical activity interventions during substance use disorder treatment excluding tobacco: A systematic review

Substance use disorder is a worldwide issue that entails negative health and physical activity is a promising complementary therapy for alleviating the consequences. The objective of this reviews is to characterize physical activity interventions offered in the literature and explore their effects during treatment for people with substance use disorders with excluding studies focusing only on tobacco use. A systematic search of seven databases on articles including a physical activity intervention during a treatment for substance use disorder was done and an examination of the presence of bias was performed. A total of 43 articles including 3135 participants were identified. Most studies were randomized controlled trial (81%), followed by pre-post design (14%) and cohort studies (5%). The most common physical activity intervention identified was of moderate intensity, 3 times per week (≈ 1 hour) for 13 weeks. Cessation/reduction of substance use was the most studied outcome (21 studies, 49%), and 75% showed a decrease in substance use following physical activity intervention. Aerobic capacity was the second most studied effect (14 studies, 33%), with more than 71% of studies showing improvement. Twelve studies (28%) reported a decrease of depressive symptoms. Physical activity interventions in a treatment for substance use disorder seem to be a promising, but more methodologically rigorous scientific studies are needed.

The relationship between beliefs in substance craving and quality of life among narcotics anonymous: a cross-sectional study in southeastern Iran

BACKGROUND

Addiction is a chronic and relapsing disorder characterized by compulsive drug seeking and lasting changes in the brain. Low quality of life may influence the substance craving, which leads to relapsing. Therefore, the present study aimed to investigate the relationship between beliefs in substance craving and quality of life among narcotics anonymous.

METHODS

This cross-sectional study was performed on 202 narcotics anonymous in Kerman, southeastern Iran. Convenience sampling was used to select anonymous patients in the Narcotics Anonymous (NA) association in Kerman city. Narcotics anonymous completed the demographic questionnaire, the Craving Beliefs Questionnaire (CBQ), and the World Health Organization Quality of Life-BREF (WHOQOL-BREF). Multiple linear regression model was used to determine the predictors of craving beliefs. The data were then analyzed using SPSS 22.

RESULTS

The mean age of the participants was 38.48 ± 11.32 years. The majority of the samples were male (86.1%), married (65.4%), educated (93.6%) and urban (86.1%). The mean scores of craving beliefs and overall Quality of Life (QOL) were 77.58 ± 20.70 and 64.42 ± 23.13, respectively. Forty-two-point 1% had high level of craving beliefs. We found a significant negative and weak correlation between beliefs in substance craving, physical health domain (r = -0.16, p = 0.02), and overall quality of life (r = -0.15, p = 0.03). History of crack use, job, and physical health domain of QOL were predictors of beliefs in substance craving among the NAs.

CONCLUSION

Based on the study results, the participants had a high level of substance craving, and some aspects of the quality of life had an impact on the beliefs of addiction. However, it is necessary to conduct more studies in this field; psychological interventions and programs to increase the quality of life may reduce the substance craving.

Systematic review of guidelines for managing physical health during treatment for substance use disorders: Implications for the alcohol and other drug workforce

ISSUES

Substance use disorders are associated with significant physical health comorbidities, necessitating an integrated treatment response. However, service fragmentation can preclude the management of physical health problems during addiction treatment. The aim of this systematic review was to synthesise the recommendations made by clinical practice guidelines for addressing the physical health of people attending alcohol and other drug (AOD) treatment.

APPROACH

An iterative search strategy of grey literature sources was conducted from September 2020 to February 2021 to identify clinical practice guidelines. Content pertaining to physical health care during AOD treatment was extracted. Quality of guidelines were appraised using the Appraisal of Guidelines Research and Evaluation II (AGREE-II) tool.

FINDINGS

Thirty-three guidelines were included for review. Fourteen guidelines were considered high quality based on AGREE-II scores. Neurological conditions (90.9%) and hepatitis (81.8%) were the most frequent health problems addressed. Most guidelines recommended establishing referral pathways to address physical health comorbidities (90.9%). Guidance on facilitating these referral pathways was less common (42.4%). Guidelines were inconsistent in their recommendations related to oral health, tobacco use, physical activity, nutrition and the use of standardised assessment tools.

IMPLICATIONS AND CONCLUSIONS

Greater consistency and specificity in the recommendations made for integrating physical health care within addiction treatment is needed. Ensuring that recommendations are applicable to the AOD workforce and to treatment services limited by funding and resource constraints should enhance implementation. Future guideline development groups should consider increased consultation with the AOD workforce and inclusion of clinical tools and decision aids to facilitate referral pathways.

Exercise in the Treatment of Addiction: A Systematic Literature Review

BACKGROUND

Exercise has been recognized as a promising and emerging treatment for individuals recovering from addiction. The purpose of this article was to systematically review scientific studies using exercise as a means to improve, sustain, or treat addictions, and to provide suggestions for the future use of exercise as a treatment method for addiction.

METHODS

Using PRISMA guidelines, a database search was conducted for articles that tested the impact of exercise interventions on addiction-related outcomes. To be included, peer-reviewed experimental design studies had to use human subjects to investigate the relationship between exercise and the treatment of or recovery from addiction. Garrard's Matrix Method was used to extract data from reviewed articles (n = 53).

RESULTS

Nearly three quarters of the studies reviewed documented a significant change in addiction-related outcomes (e.g., more days abstinent, reduced cravings) in response to exercise exposure, particularly while someone was receiving treatment at an in or outpatient clinic. Many studies investigated the effect of acute bouts of exercise on nicotine dependence, and many studies had small sample sizes, leaving room for future research on how exercise might benefit people recovering from substance and process addictions.

CONCLUSION

Results affirm that exercise can be a helpful aspect of addiction treatment. Future researchers should investigate different exercise settings (e.g., group-based exercise vs individual) and explore exercise maintenance and the long-term outcomes following discharge from treatment facilities.

The Effectiveness of Exercise as an Adjunct Intervention to Improve Quality of Life and Mood in Substance Use Disorder: A Systematic Review

Introduction: Quality of life and affective outcomes offer a perspective of the burden of disease experienced by people with substance use disorder. This can be considered an alternative measure of substance use disorder severity. This review aims to evaluate the impact of exercise as a novel intervention on quality of life and affect in substance use disorder. Method: Medline, CINAHL, Amed, Web of Science core collections, Embase, PsychINFO and SportDISCUS databases were searched from inception to August 2021 for studies that assessed the impact of exercise on mood, depression, anxiety and quality of life outcomes in substance use disorder. Exercise interventions of any duration were included. Results: Forty-two studies met the inclusion criteria. Quality of life scores improved with larger effects seen in studies with two or more sessions per week. Depression and anxiety scores decreased, with 19 of the 25 data sets reporting a reduction in depression (effect size 0.2-1.86) and 13 of the 17 data sets reporting a reduction in anxiety (effect sizes 0.2-1.42). Mood improved in six of the seven data sets reviewed with effect sizes ranging from 0.34 to 1.13. Discussion: Included studies had numerous methodological flaws therefore results need to be interpreted with caution. Further research needs to be completed with more rigorous methodologies to support these results. Conclusions: Results indicate promising responses to exercise as a novel intervention for quality of life and mood in substance use disorder, however further research of high methodological quality is needed to confirm.

Aerobic exercise as a promising nonpharmacological therapy for the treatment of substance use disorders

Despite the prevalence and public health impact of substance use disorders (SUDs), effective long-term treatments remain elusive. Aerobic exercise is a promising, nonpharmacological treatment currently under investigation as a strategy for preventing drug relapse. Aerobic exercise could be incorporated into the comprehensive treatment regimens for people with substance abuse disorders. Preclinical studies of SUD with animal models have shown that aerobic exercise diminishes drug-seeking behavior, which leads to relapse, in both male and female rats. Nevertheless, little is known regarding the effects of substance abuse-induced cellular and physiological adaptations believed to be responsible for drug-seeking behavior. Accordingly, the overall goal of this review is to provide a summary and an assessment of findings to date, highlighting evidence of the molecular and neurological effects of exercise on adaptations associated with SUD.

Environmental enrichment reduces heroin seeking following incubation of craving in both male and female rats

BACKGROUND

Contemporary treatments for heroin use disorder demonstrate only limited efficacy when the goals are long term abstinence and prevention of relapse. We have demonstrated that environmental enrichment (EE) reduces cue-induced heroin reinstatement in male rats. The present study is an attempt to extend the "anti-relapse" effects of EE to female rats and to periods where incubation of craving is hypothesized to occur.

METHODS

This experiment implemented a 3-phase procedure. In Phase 1, male and female rats were trained to self-administer heroin for 15 days. Phase 2 consisted of a 3- or 15-day forced abstinence (FA) period. In Phase 3 half of the rats were placed into EE and the other half in non-EE housing and subsequently tested for responding in extinction (no heroin or cues) for 15 days followed by a cue-induced reinstatement test.

RESULTS

We found that rats in the 15 days FA condition showed significantly enhanced drug seeking during extinction, irrespective of sex. We also found that EE significantly reduced this effect. During reinstatement, EE significantly reduced drug seeking in male and female rats and in both 3- and 15-day FA groups.

CONCLUSIONS

EE, with or without prolonged FA, effectively reduced heroin seeking in male and female rats. These findings indicate that EE can reduce drug-seeking in males and females and when putative incubation of craving (i.e., prolonged abstinence period) has occurred and suggest that it may aid in the development of future long-term behavioral treatments for individuals at risk for heroin relapse.

Exercise Pills for Drug Addiction: Forced Moderate Endurance Exercise Inhibits Methamphetamine-Induced Hyperactivity through the Striatal Glutamatergic Signaling Pathway in Male Sprague Dawley Rats

Physical exercise reduces the extent, duration, and frequency of drug use in drug addicts during the drug initiation phase, as well as during prolonged addiction, withdrawal, and recurrence. However, information about exercise-induced neurobiological changes is limited. This study aimed to investigate the effects of forced moderate endurance exercise training on methamphetamine (METH)-induced behavior and the associated neurobiological changes. Male Sprague Dawley rats were subjected to the administration of METH (1 mg/kg/day, i.p.) and/or forced moderate endurance exercise (treadmill running, 21 m/min, 60 min/day) for 2 weeks. Over the two weeks, endurance exercise training significantly reduced METH-induced hyperactivity. METH and/or exercise treatment increased striatal dopamine (DA) levels, decreased p(Thr308)-Akt expression, and increased p(Tyr216)-GSK-3β expression. However, the phosphorylation levels of Ser9-GSK-3β were significantly increased in the exercise group. METH administration significantly increased the expression of NMDAr1, CaMKK2, MAPKs, and PP1 in the striatum, and exercise treatment significantly decreased the expression of these molecules. Therefore, it is apparent that endurance exercise inhibited the METH-induced hyperactivity due to the decrease in GSK-3β activation by the regulation of the striatal glutamate signaling pathway.

Managing Substance Use Disorder through a Walking/Running Training Program

While emerging studies have demonstrated the benefit of exercise in Substance Use Disorder (SUD) recovery outcomes, lack of motivation to engage in exercise has been indicated as one of many perceived barriers that contribute to low recruitment and adherence rates in SUD treatment. The current study aimed to explore participants' perceptions of attending a supervised exercise program (boot camp workouts, walking/running practice, and a race event) while in treatment for SUD. A total of 109 participants were recruited to a 14-week exercise training program and 61 chose to participate in, and completed, a race at the close of the program. Interviews were conducted during weeks 6 through 14 and data were examined using Thematic Analysis. Three main themes were identified: (1) pushing forward recovery through running, (2) gaining a sense of achievement by crossing the finish line, and (3) building a sense of belonging in the program. Implications for SUD recovery programs are discussed.

The Benefits of Physical Exercise on Mental Disorders and Quality of Life in Substance Use Disorders Patients. Systematic Review and Meta-Analysis

Physical exercise seems to have a promising effect on numerous variables related to the recovery of drug-dependent patients. However, some contradictions are found in the literature. The aim of this study was to perform a systematic review and meta-analysis in order to identify the effect of physical exercise on mental disorders, quality of life, abstinence, and craving, and make a comparison of the effect of exercise depending on the type of program. A search for articles was conducted using PubMed, Web of Science, and Scopus databases. Studies were selected that measured the acute effects or long-term effect (≥2 weeks) of exercise in patients who met criteria for alcohol use disorders or substance use disorders. A total of 59 studies were included. An effect of exercise on quality of life and mental disorders was identified. Subgroup analysis revealed an effect of exercise on stress (SMD = 1.11 (CI: 0.31, 1.91); z = 2.73; p = 0.006), anxiety (SMD = 0.50 (CI: 0.16, 0.84); z = 2.88; p = 0.004) and depression (SMD = 0.63 (CI: 0.34, 0.92); z = 4.31; p < 0.0001), and an effect of exercise on the eight variables included in the SF36 test. The results also showed a trend towards a positive effect on craving (SMD = 0.89 (CI: −0.05, 1.82); z = 1.85, p = 0.06). Body-mind activities and programs based on improving physical conditions produced similar results in mental disorders and quality of life. Available evidence indicates that physical exercise, both body-mind and physical fitness programs, can be effective in improving mental disorders, craving, and quality of life in drug-dependent patients.

Reinforcing exercise to improve drug abuse treatment outcomes: A randomized controlled study in a substance use disorder outpatient treatment setting

Exercise holds potential to reduce substance use, but engaging patients in exercise regimens is challenging. Contingency management (CM) interventions can directly address adherence by targeting initiation and maintenance of exercise behavior. This study evaluated the efficacy of a CM-reinforced exercise intervention as an adjunct to standard outpatient substance use disorder treatment. Participants were 120 patients with substance use disorders who were randomly assigned to standard care with CM for completing exercise goals or CM for completing general nonexercise goals weekly for a 4-month treatment period. Urine samples were tested for evidence of illicit substance use up to twice a week during treatment and at follow-ups through month 12. Results found that the CM-exercise condition demonstrated during-treatment improvements on several physical activity and relevant psychosocial functioning indices (e.g., self-efficacy for exercise). The CM-exercise condition had no advantage relative to the CM-general condition in decreasing substance use. Overall, this study adds to a small body of well-powered trials assessing effects of exercise interventions as adjunct treatment for substance use disorders and finds no benefit over an alternate CM approach in terms of drug abstinence.

Operationalising the quality of life construct in studies of alcohol and drug residential rehabilitation programme clients: A systematic review

INTRODUCTION AND AIMS

Quality of life (QOL) is increasingly recognised as an important treatment indicator in the alcohol and other drug (AOD) sector, particularly in treatment modalities providing 'whole of life programmes', such as residential rehabilitation. However, it is currently unclear how studies conducted in AOD residential rehabilitation settings have operationally defined and measured QOL. This study therefore aimed to determine current practices in defining and measuring the QOL of residential rehabilitation clients.

DESIGN AND METHODS

A systematic review of studies examining the QOL of AOD residential rehabilitation clients was conducted. Potential studies published in English between 1990 and 2018 were identified through a search of electronic databases (e.g. PsycINFO and PubMed), search engines (Google Scholar) and article reference lists.

RESULTS

The search identified a total of 1267 records, of which 16 met the inclusion criteria. Less than half of the included studies provided an operational definition of QOL. QOL was generally understood to be a subjective, multidimensional, client assessment construct. Twelve different instruments were used to assess QOL, of which two enabled clients to identify QOL dimensions important to themselves.

DISCUSSION AND CONCLUSIONS

QOL has been inconsistently measured in studies of AOD residential rehabilitation clients. As a result, the comparability and validity of research in this field may be weakened. There is a need to develop a consensual operational definition of QOL, including a core set of domains relevant to and endorsed by residential rehabilitation clients. Appropriate tools to measure client QOL need to be identified and disseminated.

Measuring the quality of life of incarcerated individuals

PURPOSE

Measuring quality of life (QoL) under incarceration can be used to track successful rehabilitation and risk of re-offending. However, few studies have measured QoL among general incarcerated populations, and it is important to use psychometrically strong measures that pose minimal burdens to respondents and administrators. The paper aims to discuss these issues.

DESIGN/METHODOLOGY/APPROACH

The aim of this analysis was to explore the utility of a short generic tool measuring overall QoL, the QOL5, in an incarcerated population. The authors drew data from the Norwegian Offender Mental Health and Addiction Study, a cross-sectional survey of 1,499 individuals from Norwegian prisons.

FINDINGS

Factor analysis suggested a unidimensional structure that explained 53.2 percent of variance in QoL scores. Intrascale correlations were high and internal consistency was acceptable ( α=0.764). The QOL5 was strongly correlated with mental health, moderately correlated with exercise frequency and weakly correlated with ward security.

PRACTICAL IMPLICATIONS

The QOL5 is a short measure that presents minimal burden to respondents and administrators. The authors recommend its further use in incarcerated populations to measure overall QoL as well as cross-cultural adaptation and validation in more languages.

ORIGINALITY/VALUE

In this analysis of the largest published sample to date of incarcerated individuals and their QoL, the QOL5 appears to be an acceptable and valid measure of overall QoL.

Effectiveness of Mindfulness-based Relapse Prevention on Quality of Life and Craving in Methadone-treated Patients: A Randomized Clinical Trial

Background

Quality of life (QOL) is always considered as a final consequence of clinical trials, interventions, and health care. The results of studies indicate that addiction leads to lower QOL. However, studies have been conducted on the effectiveness of mindfulness-based interventions on improving QOL. The aim of this study was to investigate the efficacy of mindfulness-based relapse prevention (MBRP) on QOL and craving in methadone-treated patients.

Methods

This study was conducted in Qom, Iran, in 2017. A sample of 70 methadone-treated patients were randomly selected and assigned to two groups (intervention and control). Participants in both groups completed the 36-item Short Form (SF-36) QOL Questionnaire and Craving Beliefs Questionnaire (CBQ) at the beginning of the study (pre-test), 8 weeks after the study (post-test), and two months after the study (follow up). In this study, the experimental group received 8 training sessions on mindfulness prevention, while the control group did not receive general information about addiction and did not receive any psychological intervention. Finally, data of 63 patients were analyzed with the SPSS software, chi-square test, t-test, and repeated-measures ANOVA.

Findings

The results of repeated-measures ANOVA showed that there was no significant difference between intervention and control groups in the pre-test, but MBRP in the intervention group significantly increased the scores of QOL and decreased the scores of craving, significantly (P < 0.001).

Conclusion

The findings of present study indicate that MBRP training can increase the psychological and physical health in dependent methadone-treated patients and decrease craving. These findings suggest that mindfulness training can be used as an effective intervention for improving QOL and reducing craving.

Effects of core stabilization exercises on pulmonary function, respiratory muscle strength, and functional capacity in adolescents with substance use disorder: Randomized controlled trial

BACKGROUND

Adolescent substance abuse is a serious and growing problem worldwide. The aim of this study was to investigate the effects of core stabilization exercises on pulmonary function, respiratory muscle strength, and functional capacity in adolescents with substance use disorder (SUD).

METHODS

This was a prospective randomized controlled trial. A total of 49 adolescent male patients with SUD were randomly assigned to either the exercise group (n = 25; mean age 16.6 years) or the control group (n = 24; mean age 16.7 years), for 6 weeks. All participants underwent a medical and behavioral therapy program 5 days a week for 6 weeks. The exercise group received five core stabilization exercises combined with deep breathing as a group training for 45 to 60 minutes, twice a week for 6 weeks, and the control group received recreational activities in addition to the usual care for 45 to 60 minutes, twice a week for 6 weeks. Spirometry, maximal inspiratory and expiratory pressures, and the 6-minute walk test were performed and measured at baseline and after training.

RESULTS

There were significant improvements in maximal inspiratory pressure (24.16 cm H₂ O; P < 0.0001), maximal expiratory pressure (30.28 cm H₂ O; P < 0.0001), forced vital capacity (5.80% predicted, P < 0.0001), forced expiratory volume in 1 second (7.34% predicted; P = 0.002), peak expiratory flow (13.32% predicted; P = 0.0003), forced expiratory flow 25%-75% (11.84% predicted; P = 0.027), and the 6-minute walking distance (65.84 m; P < 0.0001) in the exercise group compared with the control group.

CONCLUSIONS

Core stabilization exercise can improve pulmonary function, respiratory muscle strength, and functional capacity in adolescents with SUD.

The effect of exercise as adjunctive treatment on quality of life for individuals with alcohol use disorders: a randomized controlled trial

Background

A physically active lifestyle contributes to the prevention of lifestyle diseases, promotion of physical health, and reduction of pain, among other benefits. Being physically active also promotes mental health for many individuals, in the form of improved mood, increased self-efficacy and reduced risk of depression. Alcohol-dependent individuals may experience a better quality of life when supplementing their treatment with physical exercise. This study aimed to evaluate the effect of exercise on Quality of Life among patients with alcohol use disorder in a large randomized controlled trial.

Methods

The study had three arms: Patients were allocated to (A) treatment as usual, (B) treatment as usual and supervised group exercise two days a week of one hour each, (C) treatment as usual and individual physical exercise minimum two days a week. Duration of the intervention was six months. Data on values of Quality of Life were collected at baseline (before treatment start and at time of enrollment in the study), and at follow-up (at six months after enrollment in the study) using the EQ-5D questionnaire and the EQ-VAS. The sample consisted of 117 consecutive patients, and the follow-up rate was 66.6%. Intention-to-treat analyses were conducted to evaluate the effect of exercise on quality of life.

Results

Although not statistically significant, a substantial portion of the participants in the individual exercise condition reported that they had no pain or discomfort (one of the five quality of life dimensions measured by EQ-5D questionnaire) compared to the controls at follow-up. No difference was found between the groups regarding the EQ-VAS.

Conclusion

The exercise intervention had no effect on quality of life for patients with alcohol use disorder, nor was quality of life improved across the total sample. More research in how to improve quality of life for patients with alcohol use disorder is needed.

Performance of the WHOQOL-BREF among Norwegian substance use disorder patients

BACKGROUND

Quality of life (QoL) is an established outcome measure of substance use disorder treatment. The WHOQOL-BREF is the gold standard tool, but its appropriateness for particularly vulnerable patient populations must be further explored. This article examines the scaling qualities of the WHOQOL-BREF in a Norwegian substance use disorder population, and explores relationships with social and health variables.

METHODS

107 participants in a larger national treatment study provided data during structured interviews. Item responses, responsiveness, and domain scaling qualities are reported. General linear models identified correlates of impaired QoL.

RESULTS

Three out of four domains exhibited acceptable scaling qualities, while the social relationships domain had low internal validity. 59% of the variance in physical health QoL was explained in our model by the negative main or interaction effects of depression, unemployment, social isolation, smoking, residential treatment, and weight dissatisfaction. 52% of the variance in psychological health QoL was explained by depression and being single. Depression also had significant main effects in social relationships QoL (R2 = .27) and environment QoL (R2 = .39), and social isolation and exercise had further interaction effects in environment QoL.

CONCLUSIONS

After one year in treatment, the impact of low social contact in reducing QoL, rather than specific substance use patterns, was striking. The social relationships domain is the shortest in the WHOQOL-BREF, yet social variables were important in other areas of QoL. Social support could benefit from more attention in treatment, as a lack of social support seems to be a strong risk factor for poor QoL in various domains. The WHOQOL-BREF exhibits otherwise satisfactory measurement characteristics and is an appropriate tool among this population.

Inmates with Harmful Substance Use Increase Both Exercise and Nicotine Use Under Incarceration

Exercise is increasingly understood as an important resource for people who engage in harmful substance use, including those in prison. Little is known about how inmates adopt various health behaviors during incarceration, without interventions. This cross-sectional study analyzed self-reports from 1464 inmates in Norwegian prisons in 2013–2014, compared them according to harmful substance use pre-incarceration, and explored changes in exercise and nicotine use during incarceration. Results were presented in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Inmates with harmful substance use reported higher rates of smoking, smokeless tobacco, and physical inactivity pre-incarceration than inmates without harmful use. However, inmates with harmful use also exhibited more behavioral changes: they adopted exercise, ceased smoking, and adopted smokeless tobacco at higher rates during incarceration than the non-harmful group, to the extent that inmates with harmful use exercised during incarceration more. Exercise is being taken up by a significant proportion of inmates, and may in particular be a replacement behavior for substance use. However, unhealthy behaviors also begin or are maintained. If prisons were used as an arena to facilitate healthy behaviors, the public health benefits to a marginalized group such as substance-using inmates could be substantial.

Physical Activity Preferences and Attitudes of Individuals With Substance Use Disorders: A Review of the Literature

Substance use disorders (SUDs) are prevalent in the United States and costly to society. SUDs contribute significantly to decreased quality of life and overdose deaths. Physical activity (PA) interventions may be one efficacious method to improve recovery and long-term abstinence from substance use; although PA interventions have resulted in positive physical and psychological outcomes, their adherence and attrition rates have been problematic. To address lack of adherence and high attrition rates, it is important to understand the preferences and attitudes for PA among patients in SUD treatment. We, therefore, conducted a literature review to examine preferences and attitudes for PA among adults with SUDs. Five articles met inclusion and exclusion criteria. The findings from this small sample of studies suggest that adults with SUDs are interested in PA. Walking, strength training, and cycling were the activities preferred most frequently. Participants said that they would like to engage in these activities either alone or with small groups and would prefer their exercise options to be located at facilities they already frequented, such as treatment clinics. Nurses are well positioned to assess patient preferences and attitudes and to enhance recovery efforts in this population. Further exploration of this population's unique preferences and attitudes regarding PA may lay the groundwork for efficacious PA interventions with improved adherence and attrition rates, which may lead to improved recovery outcomes.

Relationship of hope, sense of community, and quality of life

This study examined the role of hope and community in achieving and/or maintaining a successful recovery, and their relationships to quality of life for individuals in recovery. The sample included 229 participants in 42 Oxford House sober living homes in 3 locations in the United States. In this cross-sectional investigation, we assessed whether hope and sense of community were predictors of quality of life for individuals living in recovery homes. Findings indicated that both hope and sense of community were predictors supporting contextual as well as individual characteristics as possible influences on recovery trajectories. These findings have implications for both individual and systems-level resource or competency-based interventions, and they suggest one of the important functions of a recovery residence is in the creation of a sense of community.

The Effect of the Cognitive-behavioral Model-based Psychoeducation and Exercise Intervention on Quality of Life in Alcohol Use Disorder

PURPOSE

The aim of the study was to assess the effect of the cognitive behavior model (CBM)-based psychoeducation and exercise intervention on quality of life (QoL) in alcohol use disorder (AUD).

DESIGN

This study was a non-randomized controlled trial.

METHODS

CBM-based psychoeducation and exercise intervention was applied to the experimental group four times a week for 6weeks; no intervention was applied to the control group.

FINDINGS

No difference was seen between the points of pretest QoL of the experimental and control groups (p>0.05). However, according to the posttest, the experimental group's mean score of QoL was higher than the control groups (p<0.05).

CONCLUSION

It was found that CBM-based psychoeducation and exercise intervention applied to individuals with AUD affected the QoL positively.

CLINICAL RELEVANCE

CBM-based psychoeducation and exercise intervention can be used by nurses to improve AUD individuals' quality of life.

Exercise as a Sex-Specific Treatment for Substance Use Disorder

PURPOSE OF REVIEW

Exercise is a promising treatment for substance use disorder that may reduce withdrawal symptoms and prevent relapse. In this review, we discuss recent evidence from clinical and preclinical studies for its efficacy, from a behavioral to a molecular level, in order to understand the exercise conditions that lead to beneficial effects. We also highlight the few recent findings of sex-specific differences.

RECENT FINDINGS

Clinical and preclinical findings show that exercise decreases withdrawal symptoms, including craving, in both males and females. Evidence from clinical studies support the efficacy of exercise to prevent relapse to smoking, although further research is needed to examine sex differences, establish long-term efficacy, and to determine if effects extend to other substance use disorders. Preclinical findings also support the potential utility of exercise to prevent relapse with evidence suggesting that its efficacy is enhanced in males, and mediated by blocking drug-induced adaptations that occur during early abstinence.

SUMMARY

Sex differences and timing of exercise availability during abstinence should be considered in future studies examining exercise as an intervention for relapse. A better understanding of the neurobiological mechanisms underlying the efficacy of exercise to reduce withdrawal symptoms and prevent relapse is needed to guide its development as a sex-specific treatment.

Building abstinent networks is an important resource in improving quality of life

AIMS

To investigate changes in social network and quality of life of a substance use disorder cohort as they progressed through treatment.

DESIGN

Multi-site, prospective, observational study of 338 adults entering substance use disorder treatment.

SETTING

Patients at 21 facilities across Norway contributed baseline data when they initiated treatment, and follow-up data was collected from them one year later.

METHODS

The cohort was divided into those who completed, dropped out, and remained in treatment one year after treatment initiation. For each treatment status group, general linear models with repeated measures analyzed global and social quality of life with the generic QOL10 instrument over time. The between-group factor was a change in social network variable from the EuropASI.

FINDINGS

Those who gained an abstinent network reported the largest quality of life improvements. Improvements were smallest or negligible for the socially isolated and those who were no longer in contact with the treatment system.

CONCLUSIONS

Developing an abstinent network is particularly important to improve the quality of life of those in substance use disorder treatment. Social isolation is a risk factor for impaired quality of life throughout the treatment course.

Exercise as adjunctive treatment for alcohol use disorder: A randomized controlled trial

Aims

To examine whether physical activity as an adjunct to outpatient alcohol treatment has an effect on alcohol consumption following participation in an exercise intervention of six months’ duration, and at 12 months after treatment initiation.

Methods

The study is a randomized controlled study with three arms: Patients allocated to (A) treatment as usual, (B) treatment as usual and supervised group exercise, (C) treatment as usual and individual physical exercise. The primary outcome measure was excessive drinking six months after treatment start and completion of the intervention. A logistic regression model was used to evaluate the odds of excessive drinking among the three groups, based on intention-to-treat. Changes in level of physical activity in all three groups were tested by using a generalized linear mixed model. A multiple linear model was used to test if there was an association between amount of performed physical activity and alcohol consumption.

Results

A total of 175 patients (68.6% male) participated. Response rates were 77.7% at six months and 57.1% at 12 months follow-up. OR 0.99 [95% CI: 0.46; 2.14], p = 0.976 for excessive drinking in the group exercise condition, and 1.02 [95% CI: 0.47; 2.18], p = 0.968 in the individual exercise condition, which, when compared to the control group as reference, did not differ statistically significantly. Participants with moderate level physical activity had lower odds for excessive drinking OR = 0.12 [0.05; 0.31], p<0.001 than participants with low level physical activity. Amount of alcohol consumption in the intervention groups decreased by 4% [95% CI: 0.03; 6.8], p = 0.015 for each increased exercising day.

Conclusions

No direct effect of physical exercise on drinking outcome was found. Moderate level physical activity was protective against excessive drinking following treatment. A dose-response effect of exercise on drinking outcome supports the need for implementing physically active lifestyles for patients in treatment for alcohol use disorder.

Exercise in the Treatment of Youth Substance Use Disorders: Review and Recommendations

Substance use disorders among youth represent a significant public health concern. It is well established that regular exercise provides important physical and mental health benefits; however, evidence for the role of exercise as an adjunct component within substance use disorder treatment is scarce. In this review, we identify factors associated with the development and persistence of substance use disorders among youth, identify current treatment modalities, and present evidence to support the efficacy of incorporating exercise participation during rehabilitation. We also provide a series of recommendations for future research that explores the feasibility and effectiveness of exercise participation as a complement to substance use disorder treatment among youth.

Interventions to improve lifestyle and quality-of-life in patients with concurrent mental illness and substance use

BACKGROUND

Patients with co-existence of psychiatric disorders and substance use have an increased risk of premature death. This is attributable to a higher prevalence of physical comorbidities and a lifestyle related to substance use. Furthermore, they experience low quality-of-life (QoL). Studies addressing lifestyle interventions for these patients are warranted.

AIMS

To investigate the physical health and QoL in patients with co-existence of psychiatric disorders and substance use, and to analyse for changes in their (a) health, (b) substance use, and (c) QoL after a 24-month health-promotion programme. Further aims were to investigate associations between (a) QoL and number of interventions, (b) QoL and patient characteristics, and (c) QoL and length of participation in the intervention.

METHODS

In this naturalistic cohort study, 64 non-selected patients were engaged in health-promoting interventions added to contemporary treatments. QoL and clinical variables were measured at the beginning of and continuously during the programme by means of the WHOQoL-Bref questionnaire.

RESULTS

At enrolment, the patients' intake of cannabis and alcohol was high. During follow-up, patients consumed significantly fewer caffeinated beverages (p = .038) and fast-food meals (p = .018), and slept significantly less (p = .032). The average dose of antipsychotic medication increased significantly (p = .015). QoL was low at enrolment, but improved significantly overall (p = .009) and in the psychological (p = .020) and environmental domains (p = .012) at follow-up. The difference in total QoL was positively associated with the number of interventions attended.

CONCLUSION

This programme shows promise in addressing health promotion for these patients and can easily be integrated into contemporary treatments.

Exercising alcohol patients don't lack motivation but struggle with structures, emotions and social context - a qualitative dropout study

BACKGROUND

Exercise is an important component of a healthy lifestyle, the development of which is a relapse prevention strategy for those with alcohol use disorder. However, it is a challenge to create exercise interventions with a persistent behavioural change. The aim of this qualitative study was to investigate perceived barriers to participation in an exercise intervention among alcohol use disorder patients, who dropped out of the intervention program. Furthermore, this study aims to propose possibilities for a better practice of future intervention studies based on the participants' experiences and suggestions.

METHODS

Qualitative interviews with 17 patients who dropped out from an exercise intervention in an outpatient treatment centre about their experiences and reasons for dropping out. Social cognitive theory informed the development of the interview guides and systematic text condensation was used for analysis.

RESULTS

Analysis revealed three central themes: 1) Structural barriers described as the type of exercise and the timing of the intervention, 2) Social barriers described as need for accountability and unsupportive relations, and 3) Emotional barriers described as fear, guilt and shame, and negative affect of the intervention on long term.

CONCLUSIONS

Future exercise interventions should include socio-psychological support during the first weeks, begin shortly after treatment initiation instead of concurrently, and focus on garnering social support for participants in both the intervention context and among their existing network in order to best reduce barriers to participation.

TRIAL REGISTRATION

This study was retrospectively registered at Current Controlled Trials ISRCTN74889852 on 11 July 2013.

Exercise as an Adjunctive Treatment for Substance Use Disorders: Rationale and Intervention Description

Substance use disorders (SUDs) are maladaptive patterns of substance use that are associated with psychiatric comorbidity, unhealthy lifestyle choices, and high rates of relapse. Exercise is associated with a wide range of acute and long-term benefits for both mental and physical health and is presently being investigated as a promising adjunctive treatment for SUD. Despite positive effects of regular physical activity on treatment outcomes and risk factors for relapse, low adherence and high attrition rates limit the benefits derived from exercise interventions. Lack of motivation is one of many perceived barriers to initiating exercise that contributes to poor adherence to interventions. In the present article, we describe the protocol for a novel, integrated exercise intervention that combines motivational interviewing (MI), a client-centered approach designed to enhance intrinsic motivation and resolve ambivalence toward change, and contingency management (CM), a behavioral treatment that provides monetary incentives for the completion of target behaviors. The protocol seeks to address the challenges surrounding initiation and maintenance of an exercise program at a level consistent with public health guidelines, particularly for sedentary patients. We conclude with considerations for the implementation of the intervention in SUD specific clinics.

Exercise based interventions for alcohol use disorder: A comment on motivational aspects of participation

Exercise based treatment for alcohol use disorders have shown an impact on mental health (e.g., depression or anxiety), and alcohol outcomes (e.g., craving or abstinence). However, there is a lack of information on the role of motivational aspects of participation in the process of designing exercise interventions for alcohol use disorder. This study aims to examine: (1) whether motivational aspects are taken into account when the type and delivery method of exercise interventions are chosen; (2) whether motivational aspects are taken into account post intervention; and (3) whether there are different traditions regarding payment for participants. A systematic search was conducted to identify eligible studies in order to investigate the impact of motivational aspects including payment for participation. Twelve samples including ten to 620 participants were investigated. Participants were predominantly male and in their 40s, ranging from 20 to 69 years. Aerobic exercise (running, walking, fitness) either in a group or individual condition is the most frequently used exercise form. Two studies included ball games or cycling, while only one study offered the opportunity to choose between a wide range of sports. Motivational aspects are mentioned explicitly in half of the studies, mostly with regard to adherence to participation and social integration as the reason for using a group condition. Achievement is mentioned in two studies but not explicitly with regard to planning the intervention design. Five studies include payment for participation in exercise. Findings of the present study identify that motivational aspects for participation are rarely involved in the planning of an exercise intervention. With regard to the specific psychosocial vulnerability of an alcohol use disorder population, this should be an important aspect of further research studies.

Validating the generic quality of life tool "QOL10" in a substance use disorder treatment cohort exposes a unique social construct

Background

Generic quality of life (QoL) instruments provide important measures of self-reported wellbeing that can be compared across healthy and clinical populations. The aim of this analysis is to validate the ten-item QoL instrument “QOL10”, as well as to confirm the validity of the embedded “QOL5” questionnaire and single-item “QOL1” in measuring overall QoL among adults in a substance use disorder treatment study.

Methods

We used exploratory factor analysis and measured internal and convergent validity of the QOL10 against the gold standard measure of the WHOQOL-BREF, in a subsample of 107 participants in a substance use disorder treatment study.

Results

The QOL10 displayed internal and convergent validity to the gold standard measure. Factor analysis revealed a two-factor structure that can be interpreted as “social QoL”, containing items about relationships and social functioning, and “global QoL”, comprised of items about health, working ability, self-evaluation, and an overall QoL estimation.

Conclusions

The QOL10 provides clinically useful and valid measures of social-related QoL and global QoL via two subscales. Interestingly, the QOL10’s social QoL measure, from the current sample, had little relationship to the analyzed groups previously reported to have differential global QoL: social QoL appears to be not only conceptually distinct from global QoL, but also to be less influenced by typical substance- and treatment-specific factors.

Beneficial effects of Tai Chi for amphetamine-type stimulant dependence: a pilot study

BACKGROUND

Tai Chi is a traditional Chinese sport that is classified as a moderate exercise. Recent studies have evaluated the effectiveness of Tai Chi in substance abuse rehabilitation.

OBJECTIVES

The aim of this study was to assess the quality of life and physical effects of a Tai Chi intervention on individuals with amphetamine-type stimulant (stimulant) dependence.

METHODS

Sixty male subjects with stimulant dependence from a Shanghai Mandatory Detoxification and Rehabilitation Center participated in a 12-week trial. Tai Chi was used as an intervention in the experimental group (n = 30). The control group (n = 29) underwent standard care, which included recreation activity, gesture language exercise, and self-education. Outcome measures included the quality of life for drug addiction (QOL-DA) questionnaire [four scales consisting of physiology (e.g., energy level), psychology (e.g., depression), symptoms (e.g., physical symptoms), society (e.g., interpersonal) and fitness evaluations (assessed by body mass index, body fat, hand-grip, flexibility, balance)]. Repeated measures were used to analyze the changes over time.

RESULTS

Test scores of the QOL-DA in the Tai Chi group significantly increased after 12 weeks in the following areas: physiology, 8.71 (p = 0.005), symptoms, 4.34 (p = 0.042), society, 15.79 (p < 0.001), and total score, 10.60 (p = 0.002). A post hoc test further revealed that quality of life improved in the Tai Chi group but not in the standard care group. Physical results showed a significant interaction with balance(F(1,56) = 6.92, p = 0.011); participants in the Tai Chi group improved by 10 s while there was no change in the standard care group. Although there were no significant interactions in the fitness outcomes (i.e., hand-grip and sit-and-reach tests), the within-group factor displayed significant changes in body fat (F(1,56) = 27.79, p < 0.001) in both groups.

CONCLUSION

This study demonstrates that Tai Chi is a promising exercise that improves quality of life for individuals with stimulant dependence.

Quality of Life in Patients with Substance Use Disorders Admitted to Detoxification Compared with Those Admitted to Hospitals for Medical Disorders: Follow-Up Results

Quality of life (QoL) in patients admitted to a general hospital was compared with those admitted to a detoxification unit for the treatment of substance use disorder (SUD). This study combines data from two separate data collections: a cross-sectional study in a general hospital unit (somatic sample, N = 519) and a follow-up study in a detoxification unit (SUD sample, N = 140). A total of 659 patients recruited during 2008-2013 were included in this study. All patients completed a generic QoL questionnaire at inclusion, and the SUD sample also completed it at the six-month follow-up. SUD patients experienced comparably low physical QoL and had significantly lower psychological, social, and existential QoL domain scores when compared with the somatic sample. Mental distress and having a SUD were the major factors explaining variations in QoL, with both influencing QoL negatively. In the SUD sample, QoL improved moderately at the six-month follow-up with less improvement for the domain relationship to a partner. To facilitate the recovery of SUD patients, clinicians must view their patients' situation holistically and invest efforts into the different life domains affected by poor QoL.

Many correlates of poor quality of life among substance users entering treatment are not addiction-specific

Background

Quality of life (QoL) is an important measure and outcome within chronic disease management and treatment, including substance use disorders (SUD). The aim of this paper was to investigate correlates of poorer QoL of individuals entering SUD treatment in Norway, in order to identify subgroups that may most benefit from different interventions.

Methods

Twenty-one treatment facilities invited all incoming patients to participate. Five hundred forty-nine patients who enrolled between December 2012 and April 2015 are analyzed. QoL, substance use, mental and physical comorbidities, and exercise behaviors were measured. Multinomial regression analysis was used to determine variables significantly associated with poorer QoL.

Results

The majority of both genders (75 %) reported “poor” or “very poor” QoL at intake. Depression showed a strong association with poor QoL (relative risk ratio [RRR] 3.3, 95 % confidence interval [CI] 1.0–10.3) and very poor QoL (RRR 3.8, 1.2–11.8) among women. Physical inactivity among men was associated with very poor QoL (RRR 2.0, 1.1–3.7), as was reporting eating most meals alone (RRR 2.6, 1.4–4.8). Evaluating one’s weight as too low was also associated with poor QoL (RRR 2.0, 1.0-3.9) and very poor QoL (RRR 2.0, 1.1–3.7) among men. Consuming methadone/buprenorphine was a protective factor for men reporting poor QoL (RRR 0.5, 0.3–0.9) and very poor QoL (RRR 0.4, 0.2–0.9), as well as for women reporting very poor QoL (RRR 0.2, 0.0–0.6).

Conclusions

Factors associated with poorer QoL among other healthy and clinical populations, such as impaired social and physical well-being and psychological distress, were also seen associated in this sample. Treatment should be targeted towards patients with these particular vulnerabilities in addition to focusing on substance-related factors, and interventions proven to improve the QoL of other populations with these vulnerabilities should be explored in a SUD context.

Researcher Linguistic Vulnerability: A Note on Methodological Implications

We reflect on the experiences of a researcher conducting a pilot exercise project with marginalized research participants within the substance use disorder treatment field, in a language that was nonnative to her. While the project collected and analyzed quantitative data, the researcher was motivated by qualitative inquiry's commitment to reducing participant-researcher distance and power differences. Despite multiple sources of power imbalances favoring the researcher, the ability of participants to speak their native language to a nonnative researcher, and the researcher's active recognition of her linguistic vulnerability, appeared to afford them an unexpected source of power within the context of the project. We discuss the researcher's observations of these power dynamics and their implications for cross-cultural research and when working with marginalized research participants.

Evaluating Exercise as a Therapeutic Intervention for Methamphetamine Addiction-Like Behavior

The need for effective treatments for addiction and dependence to the illicit stimulant methamphetamine in primary care settings is increasing, yet no effective medications have been FDA approved to reduce dependence [1]. This is partially attributed to the complex and dynamic neurobiology underlying the various stages of addiction [2]. Therapeutic strategies to treat methamphetamine addiction, particularly the relapse stage of addiction, could revolutionize methamphetamine addiction treatment. In this context, preclinical studies demonstrate that voluntary exercise (sustained physical activity) could be used as an intervention to reduce methamphetamine addiction. Therefore, it appears that methamphetamine disrupts normal functioning in the brain and this disruption is prevented or reduced by engaging in exercise. This review discusses animal models of methamphetamine addiction and sustained physical activity and the interactions between exercise and methamphetamine behaviors. The review highlights how methamphetamine and exercise affect neuronal plasticity and neurotoxicity in the adult mammalian striatum, hippocampus, and prefrontal cortex, and presents the emerging mechanisms of exercise in attenuating intake and in preventing relapse to methamphetamine seeking in preclinical models of methamphetamine addiction.
