Personal and contextual factors in substance abuse treatment among racial and ethnic minorities: Studies from the NIDA clinical trials network

Hispanic participants in the National Institute on Drug Abuse's Clinical Trials Network: A scoping review of two decades of research

INTRODUCTION

Hispanics significantly underutilize substance abuse treatment and are at greater risk for poor treatment outcomes and dropout. Two decades of research from the National Drug Abuse Treatment Clinical Trials Network (CTN) offers an opportunity to increase our understanding in how to address the disparities experienced by Hispanics in substance abuse treatment.

METHODS

A scoping review was utilized to determine what has been learned from the CTN about Hispanic populations with substance use disorder. A systematic search was conducted within the CTN Dissemination Library and nine databases. Potentially relevant studies were independently assessed by two reviewers for inclusion.

RESULTS

Twenty-four studies were included in the review. Results identified issues in measurement, characteristics of Hispanic substance use, effective interventions, and gaps for future research. Characteristics that interfere with treatment participation were also identified including low employment rates, less likelihood of having insurance, lower rates of internet access, and increased travel time to services, as were treatment issues such as high rates of alcohol and tobacco use. Effective interventions were identified; however, the effectiveness of these interventions may be limited to specific factors.

CONCLUSIONS

Despite efforts to improve inclusion of minority populations, Hispanics remain underrepresented in clinical trials. Future research including Hispanic populations should examine measurement equivalence and consider how cultural and historical experiences, as well as patient characteristics, influence utilization of services. Finally, more studies are needed that examine the impact of structural factors that act as barriers to treatment access and engagement and result in significant disparities in treatment outcomes.

Recovery capital among migrants and ethnic minorities: A qualitative systematic review of first-person perspectives

This systematic review of 15 qualitative studies explores recovery capital among migrants and ethnic minorities (MEM). The results of the framework analysis indicate that addressing barriers to recovery and (often minority-related) root causes of problem substance use is vital to recovery among MEM, as well as building recovery capital on personal, social and community level. The review unpacks the importance of "cultural" and "spiritual" elements of recovery capital both inside and outside treatment, the interconnectedness of the different dimensions of recovery capital, as well as their intertwinement with root causes of substance use and barriers to recovery. The results point out the importance of offering culturally and trauma-sensitive relational support and building recovery capital through recovery-oriented systems of care. Moreover, this study highlights the need for further research concerning recovery in MEM populations.
