Radius of Trust Social Capital in Relation to Familism and Institutional Collectivism

Anu Realo; Jüri Allik; Brenna L. Greenfield

Countries in which people believe that “most people can be trusted” and where citizens belong to a larger number of different voluntary associations are more individualistic, emphasizing the importance of independence and freedom to choose ones own goals. The present study examines the relationship between social capital and individualism/collectivism using a measure that distinguishes between familism and institutional collectivism. Familism correlated negatively with social capital, whereas institutional collectivism practices exhibited positive associations with social capital, especially with trust and participation in voluntary organizations such as church or religious organizations and labor unions. It is concluded that in societies where trust is limited to the nuclear family or kinship alone, people have lower levels of social capital. Social capital increases as the radius of trust widens to encompass a larger number of people and social networks among whom norms of generalized reciprocity are operative.

The general alcoholics anonymous tools of recovery: the adoption of 12-step practices and beliefs.

Brenna L. Greenfield; J. Scott Tonigan

Working the 12 steps is widely prescribed for Alcoholics Anonymous (AA) members although the relative merits of different methods for measuring step work have received minimal attention and even less is known about how step work predicts later substance use. The current study (1) compared endorsements of step work on an face-valid or direct measure, the Alcoholics Anonymous Inventory (AAI), with an indirect measure of step work, the General Alcoholics Anonymous Tools of Recovery (GAATOR); (2) evaluated the underlying factor structure of the GAATOR and changes in step work over time; (3) examined changes in the endorsement of step work over time; and (4) investigated how, if at all, 12-step work predicted later substance use. New AA affiliates (N = 130) completed assessments at intake, 3, 6, and 9 months. Significantly more participants endorsed step work on the GAATOR than on the AAI for nine of the 12 steps. An exploratory factor analysis revealed a two-factor structure for the GAATOR comprising behavioral step work and spiritual step work. Behavioral step work did not change over time, but was predicted by having a sponsor, while Spiritual step work decreased over time and increases were predicted by attending 12-step meetings or treatment. Behavioral step work did not prospectively predict substance use. In contrast, spiritual step work predicted percent days abstinent. Behavioral step work and spiritual step work appear to be conceptually distinct components of step work that have distinct predictors and unique impacts on outcomes.

Review of Substance Use Disorder Treatment Research in Indian Country: Future Directions to Strive toward Health Equity

Brenna L. Greenfield; Kamilla L. Venner

Background: American Indians and Alaska Natives (AI/ANs) have disproportionately high rates of substance use disorders (SUDs). Effective treatment can help to reduce these disparities. Objective: To review and summarize the AI/AN SUD treatment research literature. Methods: The literature between 1965 and 2011 was reviewed to identify AI/AN SUD treatment articles. Results: Twenty-four unique studies were identified. Earlier treatment research focused on clinical ratings of improvement; later studies employed formal assessment measures. Poor outcomes were attributed to psychosocial factors. Where treatment outcomes appeared to be similar to comparison samples, interpretation was hampered by methodological concerns. Conclusions: The research has improved across the decades, as has the inclusion of cultural adaptations. Future research should examine factors that influence treatment effectiveness and improve retention to bolster confidence in findings. Scientific Significance: AI/ANs experience SUD-related health disparities. Understanding what factors contribute to positive treatment outcomes can help to address these disparities.

Mindfulness-based relapse prevention with racial and ethnic minority women.

Katie Witkiewitz; Brenna L. Greenfield; Sarah Bowen

Racial and ethnic disparities in the treatment of addiction have been acknowledged for several years, yet little is known about which empirically supported treatments for substance use disorders are more or less effective in treating racial and ethnic minority clients. The current study was a secondary analysis of a randomized clinical trial of two evidence-based treatments, mindfulness-based relapse prevention (MBRP) and relapse prevention (RP), as part of a residential addiction treatment program for women referred by the criminal justice system (n=70). At 15-week follow-up, regression analyses found that racial and ethnic minority women in MBRP, compared to non-Hispanic and racial and ethnic minority women in RP, reported significantly fewer drug use days (d=.31) and lower addiction severity (d=.65), based on the Addiction Severity Index. Although the small sample size is a limitation, the results suggest that MBRP may be more efficacious than traditional treatments for racial and ethnic minority women.

I'm not one of them: Barriers to help-seeking among American Indians with alcohol dependence

Kamilla L. Venner; Brenna L. Greenfield; Belinda Vicuña; Rosa Muñoz; S. Bhatt; Victoria M. O'Keefe

The majority of people with alcohol use disorders do not seek formal treatment. Research on barriers to help-seeking have only recently focused on ethnic minority populations. The present study investigated the extent to which an adult American Indian (AI) sample experienced similar and/or unique barriers to help-seeking as have been reported in the literature. Using both qualitative and quantitative methods, 56 (54% male) AIs with lifetime alcohol dependence completed a semistructured face-to-face interview and a self-administered written survey. Interviews were tape recorded, transcribed, and coded for four major themes: personal barriers, pragmatic barriers, concerns about seeking help, and social network barriers. Quantitative data provided percentage endorsing each survey item and strength of each barrier, which were categorized according to the four major themes. In previous research, most barriers questionnaires have not queried for cultural concerns or how the specific type of help may be a mismatch from the clients perspective. Given the rapidly changing racial/ethnic demography in the United States, further research addressing cultural and spiritual concerns as well as more common barriers is indicated.

Opioid use in Albuquerque, New Mexico: a needs assessment of recent changes and treatment availability

Brenna L. Greenfield; Mandy D. Owens; David Ley

BackgroundNew Mexico has consistently high rates of drug-induced deaths, and opioid-related treatment admissions have been increasing over the last two decades. Youth in New Mexico are at particular risk: they report higher rates of nonmedical prescription opioid use than those over age 25, are more likely than their national counterparts to have tried heroin, and represent an increasing proportion of heroin overdoses.MethodsCommissioned by the City of Albuquerque, semistructured interviews were conducted from April to June of 2011 with 24 substance use treatment agencies and eight key stakeholders in Albuquerque to identify recent changes in the treatment-seeking population and gaps in treatment availability. Themes were derived using template analysis and data were analyzed using NVivo 9 software.ResultsRespondents reported a noticeable increase in youth seeking treatment for opioid use and a general increase in nonmedical prescription opioid use. Most noted difficulties with finding buprenorphine providers and a lack of youth services. Additionally, stigma, limited interagency communication and referral, barriers to prescribing buprenorphine, and a lack of funding were noted as preventing opioid users from quickly accessing effective treatment.ConclusionsRecommendations for addressing these issues include developing youth-specific treatment programs, raising awareness about opioid use among youth, increasing the availability of buprenorphine through provider incentives and education, developing a resource guide for individuals seeking treatment in Albuquerque, and prioritizing interagency communication and referrals.

Introduction Although American Indians/Alaska Natives (AI/ANs) have exhibited high rates of alcohol and drug use disorders, there is a paucity of substance use disorder treatment outcome research. In addition, there exists controversy about whether evidence-based treatments (EBTs) are culturally appropriate given that they were derived mainly by and for non-Hispanic White populations and do not explicitly include aspects of AI/AN culture and worldview. Methods In this pilot study, we collaboratively culturally adapted two EBTs, Motivational Interviewing and Community Reinforcement Approach (MICRA), and evaluated substance use and psychological outcomes at 4- and 8-months post-baseline assessment. In preparation for a larger randomized clinical trial (RCT), eight tribal members (75% male) participated in this pilot treatment study. Measures included substance use, urine screens, self-efficacy, psychological distress, and hopelessness. All participants completed follow-up assessments at 4- and 8-months. Due to small sample size, effect sizes were calculated to evaluate outcomes pre- and post-treatment. Results Despite high rates of abstinence at baseline, percent days abstinent (PDA) increased at the 8-month time point for the most commonly used substances (alcohol, Hedgess g = 0.59, and marijuana, g = 0.60) and for all substances combined (excluding tobacco, g = 0.56). Improvements in psychological distress (g = − 0.66) and 5 of the 7 Addiction Severity Index domains (range of g = − 0.42 to − 0.98) also emerged. Conclusions Results suggest that culturally adapted EBTs yield significant improvements in alcohol use, psychological distress, and legal problems among AI/ANs. Future research using RCT methodology is needed to examine efficacy and effectiveness.

Spirituality is central to many Native Americans (NAs) and has been associated with recovery from substance use disorders (SUDs). However, no published questionnaire uniquely taps tribal-specific spiritual beliefs and practices. This hinders efforts to integrate traditional NA spirituality into SUD treatment and track spiritual outcomes. As part of a randomized controlled trial examining SUD treatment for NAs, we adapted the Daily Spiritual Experience Scale (DSES) in collaboration with members of a Southwest tribe to create the Native American Spirituality Scale (NASS) and measured changes in the NASS over the course of treatment. The 83 participants (70% male) were from a single Southwest tribe and seeking SUD treatment. They completed the NASS at baseline, 4, 8, and 12 months. Exploratory factor analysis of the NASS was conducted and its temporal invariance, construct validity, and longitudinal changes in the factor and item scores were examined. The NASS yielded a 2-factor structure that was largely invariant across time. Factor 1 reflected behavioral practices, while Factor 2 reflected more global beliefs. Both factors significantly increased across 12 months, albeit at different assessment points. At baseline, Factor 1 was negatively related to substance use and positively associated with measures of tribal identification while Factor 2 was unrelated to these measures. Given the importance of tribal spirituality to many NAs, the development of this psychometrically sound measure is a key precursor and complement to the incorporation of tribal spirituality into treatment, as well as research on mechanisms of change for SUD treatment among NAs and assessment of NA spirituality in relation to other aspects of health.

Alcohol use among reserve-dwelling adult First Nation members: Use, problems, and intention to change drinking behavior

Nichea S. Spillane; Brenna L. Greenfield; Kamilla L. Venner; Christopher W. Kahler

INTRODUCTION Although alcohol use was not part of traditional First Nation (FN) life, alcohol misuse currently poses a significant public health problem. There is a dearth of research efforts to understand both alcohol misuse and efforts to resolve these problems. The primary aims of this study were to 1) present descriptive data on alcohol use in FN adults living on one reserve in Eastern Canada; and 2) explore correlates of help seeking intentions and past behaviors. METHODS We administered questionnaires to 211 FN people (96 men; 113 women; 2 unknown). RESULTS Nearly two-thirds of our sample were current drinkers (N=150). Of those, 29% endorsed they needed help with their drinking, and half reported that they would probably try to cut down or stop drinking in the next year. Multiple regression analyses suggested that drinking was positively associated with a greater perceived need for help with drinking (β=.40, p=<.001). Lower scores on a measure of cultural identity (i.e., stronger FN identity) was associated with a greater perceived need for help with drinking (β=-.18, p=.04). Greater endorsement of past year attempts to stop drinking (β=.33, p<.001) and higher alcohol reduction expectancies (β=.43, p<.00) were positively associated and lower scores on cultural identity (i.e., stronger FN identity) (β=-.19, p=.03) was associated with trying to cut down or stop drinking in the next year. CONCLUSIONS Future research should explore the nature of cultural identity as a protective factor.

Race/ethnicity and racial group composition moderate the effectiveness of mindfulness-based relapse prevention for substance use disorder

Brenna L. Greenfield; Corey R. Roos; Kylee J. Hagler; Elena Stein; Sarah Bowen; Katie Witkiewitz

INTRODUCTION Mindfulness-based relapse prevention has shown promise as a treatment for substance use disorder but its efficacy according to racial/ethnic minority status and group composition is unknown. METHOD This is a secondary analysis of existing data (Bowen et al., 2014) testing individual race/ethnicity and racial/ethnic group composition as moderators of mindfulness-based relapse prevention (MBRP). Participants (N = 191; 29% female; 47% racial/ethnic minority; mean age = 39) with substance use disorder were randomized to MBRP or relapse prevention (RP). Outcomes were heavy drinking days (HDD) and drug use days (DUD) 12 months after treatment completion. Negative binominal regression models were conducted. RESULTS Analyses accounted for drug of choice. Individual race/ethnicity was a significant moderator of substance use outcomes. White participants had lower HDD in MBRP than RP (IRR = 0, 95% CI: 0,0), whereas for minority participants, there was no treatment difference in HDD. Conversely, minorities had lower DUD in MBRP than RP (IRR = 0.03, 95% CI: 0.01, 0.10), whereas for whites there was no treatment difference in DUD. Group racial/ethnic composition was a significant moderator. Participants in groups with more than half whites had lower HDD in MBRP than RP (IRR = 0.01, 95% CI: 0, 0.09), whereas for participants in groups with more than half minorities there was no treatment difference in HDD. Exploratory analyses suggested MBRP resulted in better outcomes than RP when individual race/ethnic status was reflected in the group race/ethnicity (i.e., whites in groups with more than half whites or minorities in groups with more than half minorities). CONCLUSIONS Among whites, MBRP appears to be more effective than RP in preventing heavy drinking relapse. However, among racial/ethnic minorities, MBRP appears to more effective than RP in preventing drug use relapse. This suggests that the interaction between individual race/ethnicity and group composition may influence primary outcomes.
