Blended-eLearning Improves Alcohol Use Care in Kenya: Pragmatic Randomized Control Trial Results and Parallel Qualitative Study Implications

A scoping review of substance use brief interventions in Africa

BACKGROUND

The burden of substance use in Africa is substantial. Brief interventions (BIs) are a recommended public health strategy for the prevention and early intervention for substance use problems. The objective of this scoping review was to map the literature on substance use BIs in Africa, identify gaps, and provide directions for future research.

METHODS

The scoping review was guided by the Arksey O'Malley Framework and the PRISMA-Scoping review (PRISMA-ScR) guidelines. A search of five bibliographic databases (PubMed, PsychINFO, Web of Science, Cumulative Index of Nursing and Allied Professionals (CINAHL) and Cochrane Library) was conducted from inception until 1st November 2023. BIs were defined as those targeting substance use and delivered over 1-4 sessions, or interventions delivered over more than four sessions if the authors referred to them as 'brief'. Results of the review have been summarized descriptively and organized by three broad outcomes: BI effect and feasibility; feasibility and effectiveness of training providers to deliver BIs; Other outcomes i.e. cost-effectiveness, BI adaptation and development, and knowledge attitude and practice of BIs by providers.

RESULTS

Of the 80 studies that were eligible for inclusion, 68 investigated the effect and feasibility of BIs, six studies investigated the feasibility and effectiveness of training providers to deliver BIs, and six explored other outcomes. Most of the available studies had been conducted in Eastern and Southern Africa. BIs were largely based on motivational interviewing and psychoeducational principles. Overall, the BIs were reported as feasible to implement from the perspective of policy makers, providers, and the intervention recipients. Findings on the effect of BIs on substance use were mixed. Key evidence gaps emerged. There was paucity of BI research focusing on substances other than alcohol, and there was limited literature on feasibility and efficacy of BIs among youth and adolescents.

CONCLUSION

The results of this scoping review provide important directions for future substance use BI research in Africa.

FRAMES Elements Associated With Alcohol Treatment Research Assessments and Related Behavior Change

OBJECTIVE

Assessment reactivity research has contributed substantially to our understanding of alcohol treatment research protocols influencing clinical outcomes. The state of the science is such that relatively little is known about how alcohol treatment research participation influences behavior. The purpose of this study was twofold: (a) to determine the distribution of FRAMES elements (i.e., Feedback, personal Responsibility, Advice, a Menu of options, Empathic style of interaction, and support for Self-efficacy) contained in alcohol treatment research assessment interviews; and (b) to examine their association with subsequent alcohol use among a sample of clients presenting for alcohol use disorder treatment.

METHOD

Audiotaped recordings of participant (n = 189) research assessment interviews were converted to digital recordings and reviewed for FRAMES elements using the FRAMES Checklist Instrument.

RESULTS

Feedback, personal responsibility, empathic style of interaction, and support for self-efficacy were the more frequently occurring elements across follow-up periods. Alternatively, menu of options and advice occurred infrequently. Feedback and support for self-efficacy predicted subsequent alcohol use, although the association between feedback and alcohol use was unexpectedly positive.

CONCLUSIONS

As part of the assessment interview process, alcohol treatment research participants receive multiple instances of feedback and support for self-efficacy specific to their alcohol use that are predictive of changes in alcohol use.

Blended-eLearning Impact on Health Worker Stigma Toward Alcohol, Tobacco, and Other Psychoactive Substance Users

This study evaluated factors affecting the completion of blended-eLearning courses for health workers and their effect on stigma. The two courses covered the screening and management of harmful alcohol, tobacco, and other substance consumption in a lower-middle-income country setting. The courses included reading, self-reflection exercises, and skills practice on communication and stigma. The Anti-Stigma Intervention-Stigma Evaluation Survey was modified to measure stigma related to alcohol, tobacco, or other substances. Changes in stigma score pre- and post-training period were assessed using paired t-tests. Of the 123 health workers who registered, 99 completed the pre- and post-training surveys, including 56 who completed the course and 43 who did not. Stigma levels decreased significantly after the training period, especially for those who completed the courses. These findings indicate that blended-eLearning courses can contribute to stigma reduction and are an effective way to deliver continuing education, including in a lower-middle-income country setting.
