The urgent need for contingency management among Tribal communities in the United States: Considerations for implementation, policy, and sovereignty

In two randomized controlled trials, culturally adapted contingency management (i.e., incentives provided for substance-negative urine samples) was associated with reduced alcohol and drug use among geographically diverse American Indian and Alaska Native (AI/AN) adults. In response to interest in contingency management from other Tribal and AI/AN communities, our research team in collaboration with AI/AN behavioral health experts, translated the research into practice with new AI/AN community partners. Tenets of community-based participatory research were applied to develop, pilot, and refine contingency management training and implementation tools, and identify implementation challenges. In partnership with the AI/AN communities, four members of the university team developed tools and identified implementation and policy strategies to increase the successful uptake of contingency management in each location. Through our collaborative work, we identified policy barriers including inadequate federal funding of contingency management incentives and a need for further clarity regarding federal anti-kickback regulations. Adoption of contingency management is feasible and can strengthen Tribal communities' capacity to deliver evidence-based substance use disorder treatments to AI/AN people. Unfortunately, non-evidence-based limits to the use of federal funding for contingency management incentives discriminate against AI/AN communities. We recommend specific federal policy reforms, as well as other practical solutions for Tribal communities interested in contingency management.

Factors Associated with Child Removal Among American Indian and Alaska Native People in an Alcohol Intervention Study

This study was a secondary data analysis of factors associated with alcohol-related child removal among American Indian/Alaska Native (AI/AN) adults enrolled in a clinical trial of an alcohol intervention. Among 326 parent participants, 40% reported ever having a child removed from their care in part because of the parent's alcohol use, defined here as alcohol-related child removal. Seventy-five percent of parents reported at least one separation during their own childhood (M = 1.3, SD = 1.0). In a multivariable analysis, alcohol-related child removal was associated with parental boarding school attendance. No relationship was found between alcohol-related child removal and alcohol intervention outcomes. Results may provide evidence of multigenerational child removal impacts of boarding schools on AI/AN adults receiving an alcohol use disorder intervention. Assessment of parental history of child removal by practitioners, strategies to prevent alcohol-related separation and to support reunification should be integrated into addiction treatment in AI/AN communities.

Coming together for something good: recommendations from a scoping review for dissemination and implementation science to improve indigenous substance use disorder treatment

Introduction

Dissemination and Implementation (D&I) science is growing among Indigenous communities. Indigenous communities are adapting and implementing evidence-based treatments for substance use disorders (SUD) to fit the needs of their communities. D&I science offers frameworks, models, and theories to increase implementation success, but research is needed to center Indigenous knowledge, enhancing D&I so that it is more applicable within Indigenous contexts. In this scoping review, we examined the current state of D&I science for SUD interventions among Indigenous communities and identified best-practice SUD implementation approaches.

Methods

PubMed and PsycINFO databases were queried for articles written in English, published in the United States, Canada, Australia, and New Zealand. We included key search terms for Indigenous populations and 35 content keywords. We categorized the data using the adapted and extended Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework that emphasizes equity and sustainability. RE-AIM has also been used as a primary model to consistently identify implementation outcomes.

Results

Twenty articles were identified from the original unduplicated count of over 24,000. Over half the articles discussed processes related to Reach, Adoption, and Implementation. Effectiveness was discussed by 50% of the studies (n = 10), with 25% of the articles discussing Maintenance/sustainability (n = 4). Findings also highlighted the importance of the application of each RE-AIM domain for meaningful, well-defined community-engaged approaches.

Conclusion

Finding indicated a need to prioritize Indigenous methods to culturally center, re-align and adapt Western treatments and frameworks to increase health equity and improve SUD treatment outcomes. Utility in the use of the modified RE-AIM and the continued modification for Indigenous communities was also noted.

A Systematic Review of Trauma and Substance Use in American Indian and Alaska Native Individuals: Incorporating Cultural Considerations

INTRODUCTION

Disproportionate rates of psychiatric disorders, like substance use and posttraumatic stress disorders (SUD and PTSD), exist among American Indian and Alaska Native (AI/AN) individuals. This review examines substance use and trauma in existing AI/AN literature and utilizes an AI/AN-specific model to culturally inform the relationship between these factors and provide recommendations for future research.

METHODS

We searched three databases through April 2021 for peer-reviewed articles that examined substance use and trauma in AI/AN individuals.

RESULTS

The search identified 289 articles and of those, 42 were eligible for inclusion, including 36 quantitative and 6 qualitative studies. Rates of lifetime trauma exposure varied from 21 to 98% and were correlated with increased rates of SUDs. A dose response of traumatic events also increased the likelihood of an SUD among reservation-based AI populations. Factors from the Indigenist Stress Coping model included cultural buffers such as traditional healing and cultural identity, which aided in recovery from SUD and trauma, and social stressors like boarding school attendance, discrimination, and historical loss.

CONCLUSIONS

SUD and trauma are highly correlated among AI/AN individuals though rates of PTSD are lower than might be expected suggesting resilience. However, this pattern may not be consistent across all AI/AN groups and further research is needed to better explain the existing relationship of SUD and PTSD and relevant historical and cultural factors. Further research is needed to culturally tailor, implement, and validate PTSD and SUD assessments and treatments to ameliorate these health inequities.

A clinical science guide for reviewing the cross-cultural rigor of assessments in an alcohol training clinic

A standard component of service delivery in alcohol treatment clinics is evidence-based assessment (EBA). Although EBA is essential for selecting appropriate treatment modalities for alcohol use and associated problems, there are limitations in existing EBAs concerning evidence of cultural equivalence and utility among individuals seeking alcohol treatment. However, training in EBA, addictions, and clinical applications with diverse populations all are gaps in clinical training in doctoral programs in clinical psychology. The present work used the clinical science model to review the psychometric properties, cross-cultural utility, and measurement invariance of measures in an assessment battery used in an alcohol treatment training clinic. This article describes the results of that review, recommendations for retaining or replacing common assessment measures used in alcohol treatment clinics, and recommendations for alcohol treatment clinics interested in engaging in similar processes. Findings suggested that more research is needed to evaluate the psychometric properties of EBAs utilized in an alcohol treatment assessment battery, particularly among American Indian and Alaska Native people, and to test measurement invariance across race/ethnicity and other identity groups in alcohol treatment-seeking populations. Overall, routine reviews of cultural relevance are needed in clinical settings to stay current with the emerging literature. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Contingency management for alcohol use disorder reduces cannabis use among American Indian and Alaska Native adults

OBJECTIVE

Determine whether a culturally tailored contingency management (CM) intervention targeting alcohol abstinence resulted in secondary effects on cannabis use among American Indian and Alaska Native (AI/AN) adults.

METHODS

The research team conducted this secondary data analysis to examine cannabis abstinence using data from a randomized control trial of CM for alcohol use among three AI/AN-serving organizations. One hundred and fifty-eight adults met the randomization criteria (i.e., submission of 50% or more urine samples and one alcohol-positive urine test during a 4-week, pre-randomization, observation period). For 12 weeks after randomization, participants received incentives for submitting a urine test negative for ethyl glucuronide (EtG < 150 ng/mL, CM group) or incentives for submitting a urine sample regardless of abstinence (Non-contingent [NC] Control group). Generalized linear mixed effects models assessed group differences in cannabis abstinence during the intervention, verified by urine tetrahydrocannabinol negative tests (11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid <50 ng/mL).

RESULTS

At baseline, 42.2% (n = 35) of participants in the NC group and 40.0% (n = 30) of those in the CM group had a cannabis positive urine test. An overall intervention by time interaction was detected for a cannabis negative urine test (χ2 = 13.40, p = 0.001). Compared to the NC group, the CM group had 3.92 (95% CI:1.23-12.46) times higher odds of having a cannabis negative urine test during the intervention period and 5.13 (95% CI:1.57-16.76) times higher odds of having a negative cannabis test at the end of intervention period.

CONCLUSION

CM addressing alcohol misuse may be an effective strategy for decreasing cannabis use among AI/AN adults.

Plasma cholinesterase phenotyping with use of visible-region spectrophotometry

A method that overcomes the difficulties of the 240-nm benzoylcholine method for phenotyping plasma cholinesterases has been developed. After a timed reaction, under the same reaction conditions as in the classic procedure, choline is detected at 500 nm by use of choline oxidase coupled with the peroxidase/phenol/aminoantipyrine system. Cholinesterase activity measurements, calibrated by use of choline iodide as standard, are linearly related to results obtained with propionylthiocholine as substrate at 25 degrees C (y = 0.14x + 0.17, n = 30, r = 0.98). Results of differential inhibition with dibucaine and fluoride are virtually identical with those obtained by the ultraviolet method (y = 0.97x + 4.3, r = 0.995, and y = 0.93x - 0.5, r = 0.987, respectively) and give the same classification of homo- and heterozygotes for the usual, atypical, and fluoride-resistant variants. The new method has substantial advantages in that it eliminates the difficulties associated with measuring small changes in high absorbances at a suboptimal wavelength on a steep portion of the absorption curve.

Childhood crises--who to tell?

This study describes an investigation of community attitudes in Christchurch towards sources of help for children in crisis situations. To whom the child turns is particularly important when a child is unable or unwilling to ask a parent for help. The children sampled showed a preference for informal sources of support (such as friends, relatives, rather than formal, such as teachers, crisis-counsellors, doctors). Most professionals believed children should use their services in preference to those of other professions. The adults rated formal sources of support, particularly teachers, much higher than the children. Of the formal services crisis-counsellors, and in particular the Childhelp Line, a 24-hour telephone counselling service for children, was the most preferred. The findings tend to demonstrate the value of a child-oriented crisis line to the community.
