Experiences of peer work in drug use service settings: A systematic review of qualitative evidence.

BACKGROUND: People with lived or living experiences of drug use and services have been increasingly incorporated into nonpeer-led mainstream organizational settings as a unique workforce. Despite the much discussed effectiveness of peer services in achieving measurable outcomes, limited attention has been given to the experiential aspects of peer work from the perspectives of peers, clients, or others involved. This systematic review synthesized qualitative evidence examining the experiences of peer work in nonpeer-led drug use service settings. It focused on the benefits of incorporating peers as a unique workforce, the challenges they face, and the organizational factors that influence their practices. METHODS: A search of 15 databases identified 3,940 unique citations, 33 of which met inclusion criteria. Thematic analysis was utilized to synthesize their findings. RESULTS: Foregrounding the uniqueness of peers' shared experience, studies have shown that incorporating peers into nonpeer-led settings can provide benefits at the client, organizational, and societal levels while promoting peers' personal and professional growth. The unique shared experience of peers can also present multidimensional challenges, such as triggering, boundary negotiation, and feelings of being trapped by their peer identity. To fully integrate peers into the system, organizations need to work with them to reconstruct organizational mission, culture, and structures in a way that recognizes and genuine commits to peers' unique values. CONCLUSION: This review highlights the significance of understanding peer uniqueness for organizations to create nourishing conditions for peer services and calls for future research exploring context- and setting-specific peer roles and organizational enablers and barriers.

Sex-specific and generational effects of alcohol and tobacco use on epigenetic age acceleration in the Michigan longitudinal study.

Background: Excessive alcohol and tobacco use are risk factors for poor health in both men and women, but use patterns and relationships with diseases and mortality differ between sexes. The impact of substance use on the epigenome, including DNA methylation profiles, may also differ by sex. It is also unknown whether parental substance use during childhood is associated with epigenetic changes that persist into adulthood. This study assessed the sex-specific effects of individuals' alcohol and tobacco use, as well as paternal alcohol and paternal/maternal tobacco use, on offspring's cellular aging as measured by epigenetic age acceleration. Methods: Four measures of epigenetic age acceleration (HorvathAA, HannumAA, PhenoAA, and GrimAA), the difference between chronological age and inferred age based on DNA methylation, were estimated from saliva samples. Linear mixed models tested associations between alcohol/tobacco use and epigenetic age acceleration in parents and offspring. Results: Current tobacco smoking was associated with a 4.61-year increase in GrimAA, and former tobacco smoking was associated with a 3.60-year increase in HannumAA after accounting for multiple testing (p < 0.0125). In males only, current tobacco smoking was nominally associated with a 2.19-year increase in HannumAA (p < 0.05), and this effect was significantly different than the female-specific effect (p < 0.0125). Paternal heavy alcohol use when the offspring was 12 or younger was associated with a 4.43-year increase in GrimAA among offspring (p < 0.0125). Conclusions: This study found evidence of sex-specific effects of alcohol and tobacco use, as well as paternal heavy alcohol use, on epigenetic age acceleration.

Gender differences in the transmission of risk for antisocial behavior problems across generations.

Previous studies have shown that children of alcohol use disorder (AUD) parents are more likely to develop alcohol problems as well as antisocial and other behavior problems. The purpose of this study was to examine gender discordance in the effect of early maternal and paternal influences on antisocial behaviors of boys and girls, as well as the environmental factors that moderate the parental effects. Specifically, we examined the effects of childhood and adulthood antisocial behavior of the parents on offspring antisocial behavior as young adults. We also examined whether mothers' and fathers' drinking problems when offspring were young children (6-8 years) affected offspring antisocial behavior as young adults (18-21 years). We evaluated 655 children from 339 families in the Michigan Longitudinal Study (MLS), a prospective study of AUD and non-AUD families. Path models were constructed in order to test for the parental contributions to offspring outcomes. We found that both mothers' and fathers' antisocial behavior contributed to the children's young adult antisocial behavior. Only mothers' drinking problems while their children were little had a significant effect on their sons' later drinking, but not on their daughters'. These different parental effects suggest that maternal and paternal influences may be mediated by different mechanisms.

Sex differences, gender and addiction.

This review discusses alcohol and other forms of drug addiction as both a sociocultural and biological phenomenon. Sex differences and gender are not solely determined by biology, nor are they entirely sociocultural. The interactions among biological, environmental, sociocultural, and developmental influences result in phenotypes that may be more masculine or more feminine. These gender-related sex differences in the brain can influence the responses to drugs of abuse, progressive changes in the brain after exposure to drugs of abuse and whether addiction results from drug-taking experiences. In addition, the basic laboratory evidence for sex differences is discussed within the context of four types of sex/gender differences. © 2016 Wiley Periodicals, Inc.

Sociocultural context for sex differences in addiction.

In this review, we discuss the importance of investigating both sex and gender differences in addiction and relapse in studies of humans and in animal models. Addiction is both a cultural and biological phenomenon. Sex and gender differences are not solely determined by our biology, nor are they entirely cultural; they are interactions between biology and the environment that are continuously played out throughout development. Lessons from the historical record illustrate how context and attitudes affect the way that substance use in men and women is regarded. Finally, cultural and environmental influences may differentially affect men and women, and affect how they respond to drugs of abuse and to treatment protocols. We recommend that both animal models and clinical research need to be developed to consider how contextual and social factors may influence the biological processes of addiction and relapse differentially in men and women.

Alcohol-impaired driving: average quantity consumed and frequency of drinking do matter.

OBJECTIVE: The objective of this article is to estimate and validate a logistic model of alcohol-impaired driving using previously ignored alcohol consumption behaviors, other risky behaviors, and demographic characteristics as independent variables. METHODS: The determinants of impaired driving are estimated using the US Centers for Disease Control and Prevention's (CDC) Behavioral Risk Factor Surveillance System (BRFSS) surveys. Variables used in a logistic model to explain alcohol-impaired driving are not only standard sociodemographic variables and bingeing but also frequency of drinking and average quantity consumed, as well as other risky behaviors. We use interactions to understand how being female and being young affect impaired driving. Having estimated our model using the 1997 survey, we validated our model using the BRFSS data for 1999. RESULTS: Drinking 9 or more times in the past month doubled the odds of impaired driving. The greater average consumption of alcohol per session, the greater the odds of driving impaired, especially for persons in the highest quartile of alcohol consumed. Bingeing has the greatest effect on impaired driving. Seat belt use is the one risky behavior found to be related to such driving. Sociodemographic effects are consistent with earlier research. Being young (18-30) interacts with two of the alcohol consumption variables and being a woman interacts with always wearing a seat belt. Our model was robust in the validation analysis. CONCLUSIONS: All 3 dimensions of drinking behavior are important determinants of alcohol-impaired driving, including frequency and average quantity consumed. Including these factors in regressions improves the estimates of the effects of all variables.

OxyContin misuse on a reservation: qualitative reports by American Indians in talking circles.

Few studies have addressed OxyContin use among American Indians (AIs) on reservations. Eight focus groups were conducted as "talking circles" (2006 and 2007 ) with 49 AI adults and youth. An emergent design was utilized in which the initial two circles were planned, but the subsequent six circles evolved from tribal members' input. Participants reported an increase in OxyContin use; negative effects on individuals, families, and the tribe; a lack of treatment options; and a growing problem on other reservations. Results indicate the need to further research prevalence and patterns of use to design interventions to curtail OxyContin abuse on reservations.

Solving problems of disclosure risk while retaining key analytic uses of publicly released microdata.

MEASURES USED TO PROTECT SUBJECTS in publicly distributed microdata files often have a significant negative impact on key analytic uses of the data. For example, it may be important to analyze subpopulations within a data file such as racial minorities, yet these subjects may present the greatest disclosure risk because their records tend to stand out or be unique. Files or records that are linkable create another type of disclosure risk-common elements between two files can be used to link files with sensitive data to externally available files that disclose identity. Examples of disclosure limitation methods used to address these types of issues include blanking out data, coarsening response categories, or withholding data altogether. However, the very detail that creates the greatest risk also provides insight into differences that are of greatest interest to analysts. Restricted-use agreements that provide unaltered versions of the data may not be available, or only selectively so. The public-use version of the data is very important because it is likely to be the only one to which most researchers, policy analysts, teaching faculty, and students will ever have access. Hence, it is the version from which much of the utility of the data is extracted and often it effectively becomes the historical record of the data collection. This underscores the importance that the disclosure review c ommittee s trikes a g ood b alance b etween protection and u tility. In this paper we d escrib e our disclosure review committee's (DRC) analysis and resulting data protection plans for two national studies and one administrative data system. Three distinct disclosure limitation methods were employed, taking key uses of the data into consideration, to protect respondents while still providing statistically accurate and highly useful public-use data. The techniques include data swapping, microaggregation, and suppression of detailed geographic data. We describe the characteristics of the data sets that led to the selection of these methods, provide measures of the statistical impact, and give details of their implementations so that others may also utilize them. We briefly discuss the composition of our DRC, highlighting what we believe to be the important disciplines and experience represented by the group.

Implementing trauma-informed alcohol and other drug and mental health services for women: lessons learned in a multisite demonstration project.

On the basis of the 9-site, Substance Abuse and Mental Health Services Administration-funded Women, Co-Occurring Disorders, and Violence Study, this article discusses recommendations for implementing trauma-informed mental health, substance abuse, and other support services. These guidelines for best practices represent the consensus of a diverse trauma work group that drew on both cross-site and site-specific qualitative data.

Design strengths and issues of SAMHSA's Women, Co-occurring Disorders, and Violence Study.

In 1998 the Substance Abuse and Mental Health Services Administration launched the Women, Co-occurring Disorders, and Violence Study (WCDVS). The WCDVS developed, implemented, and evaluated the outcomes and costs of comprehensive, trauma-informed treatment programs for women with a history of violence and trauma who have substance use and mental health disorders. This article discusses the overall design features of the study, issues related to such a design, results of the outcomes and cost evaluations, and suggestions for future research. The nine WCDVS sites were located across the continental United States, with six sites on the East Coast, two on the West Coast, and one in Colorado. A total of 2,729 women (1,415 in the intervention condition and 1,314 in the comparison condition) were enrolled over the 13.5-month baseline accrual period (January 2001 through February 2002). Follow-up interviews were conducted with all participants at three, six, nine and 12 months post-baseline. Women in the intervention and the comparison groups showed improvement in outcomes in four areas: alcohol use, drug use, mental health, and trauma. At six months women in the intervention group scored modestly better than women in the usual-care group for outcome measures for drug use, trauma, and mental health. At 12 months women in the intervention group maintained their improvement in drug use outcomes and continued to improve in mental health and trauma outcomes. After a start-up period, costs for services were not significantly different between the intervention and comparison groups at both follow-up points. Despite their very modest nature, the WCDVS results are promising.

Outcomes for women with co-occurring disorders and trauma: program-level effects.

Program-level effects at 6 months are reported from meta-analysis of a nine-site quasi-experimental study of comprehensive, integrated, trauma-informed, and consumer-involved services for women who have mental health problems, substance use disorders, and who have experienced interpersonal violence. The average weighted effect size is significant for the treatment condition for improved post-traumatic symptoms (p < 0.02), drug use problem severity (p < 0.02), and nearly significant for mental health symptoms (p < 0.06). There is significant heterogeneity in effect sizes across sites. Program-level variables were examined in an effort to explain this heterogeneity. The findings indicate that sites which provided significantly more integrated counseling produced more favorable results in mental health symptoms (p < 0.01) and both alcohol (p < 0.001) and drug use problem severity (p < 0.001). The same trend is observable for reductions in post-traumatic stress symptoms, although the difference does not attain statistical significance.

Outcomes for women with co-occurring disorders and trauma: program and person-level effects.

Six-month outcomes are evaluated from a 9-site quasi-experimental study of women with mental health and substance use disorders who have experienced physical or sexual abuse who enrolled in either comprehensive, integrated, trauma-informed, and consumer/survivor/recovering person-involved services (N = 1023) or usual care (N = 983). Mental health, post-traumatic stress symptoms, and substance use outcomes are assessed with multilevel regression models, controlling for program and personal characteristics. Person-level variables predict outcomes independent of intervention condition and, to a small extent, moderate intervention and program effects. In sites where the intervention condition provided more integrated counseling than the comparison condition, there are increased effects on mental health and substance use outcomes; these effects are partially mediated by person-level variables. These results encourage further research to identify the longer-term effects of integrated counseling for women with co-occurring disorders and trauma histories.
