Reducing Risky Sex among Rural African American Cocaine Users: A Controlled Trial

Systematic review of cognitive and behavioral strategies used in effective harm reduction interventions for people who use cocaine

OBJECTIVE

The aim of this systematic review is to identify cognitive and behavioral strategies that have been used in effective harm reduction interventions for people who use cocaine.

METHOD

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the search was performed on February 26, 2023 across databases including PsycInfo, PubMed, Scopus, and Web of Science. Studies were included if they (1) report the use of one cognitive or behavioral strategy, (2) have harm reduction as the objective, (3) involve participants who used cocaine as at least one of their substances, (4) be published within the last 10 years, and (5) have a randomized controlled trial design. The Cochrane RoB 2.0 Tool was used to assess risk of bias. The cognitive and behavioral strategies were extracted and organized based on their frequency of use in the studies and their corresponding outcomes.

RESULTS

The final synthesis included k = 10 studies with N = 3,567 participants. Psychoeducation strategies, influence on social norms, personalized feedback, increased self-efficacy and motivational interviewing were the most frequently used promising strategies across studies.

CONCLUSIONS

This review underscores the significance of incorporating cognitive and behavioral strategies within harm reduction interventions, as they represent a promising domain that could enhance the effectiveness of addressing cocaine use.

Cultural interventions addressing disparities in the HIV prevention and treatment cascade among Black/African Americans: a scoping review

Culture is an important determinant of HIV risk and protective behaviors; yet, we know little about how it is integrated in HIV interventions. This scoping review characterizes the integration of culture in HIV prevention and treatment interventions focused on Black/African Americans. We searched MEDLINE, PsycINFO, CINAHL, and Google Scholar for peer-reviewed manuscripts published between July 1, 2011, and June 28, 2021. Twenty-five interventions were identified, with 96% focused on prevention. Most (40%) targeted men who have sex with men or transgender women. Only three were grounded in cultural theory. Although all interventions were labeled "culturally based," only two explicitly defined culture. Moreover, there was much diversity regarding the ways in which interventions integrated cultural elements, with some conflating race/ethnicity with culture. To improve uptake and HIV-related outcomes, interventions integrating culture are greatly needed. Additionally, HIV interventions purporting to be "culturally based" must include basic information to support rigor and reproducibility.

Social network strategy as a promising intervention to better reach key populations for promoting HIV prevention: a systematic review and meta-analysis

INTRODUCTION

Key populations such as men who have sex with men (MSM), drug users and sex workers are at high risk of HIV infection, but they are marginalised and hidden. Social network strategy (SNS) is purposeful to use social networks to generate social influence, accelerate behaviour change and achieve desirable outcomes among individuals or communities and have been increasingly used for HIV interventions. This study aims to investigate the effects of SNS on HIV prevention among key populations.

METHODS

We searched six databases, including PubMed, Web of Science, Embase, Cochrane Library, ScienceDirect and Wiley for randomised controlled trials published between January 1999 and May 2019. Eligibility criteria included SNS conducted among key populations for HIV interventions, with a comparator group. Outcomes included changes in HIV high-risk behaviour, HIV seroconversion and other HIV outcomes. We used the risk ratio (RR) or mean difference with associated 95% confidence interval (CI) to assess the comparative efficacy between SNS and control methods on the selected outcomes. The GRADE system was used to assess the quality of evidence for the studies.

RESULTS

Of 2818 citations identified, 28 trails from 24 papers met the inclusion criteria. The results showed that SNS was associated with less unprotected intercourse (RR 0.79, 95% CI 0.72 to 0.86) and sex with multiple partners (0.46, 95% CI 0.33 to 0.65). Additionally, relative to the control methods, SNS significantly reduced HIV seroconversion (0.65, 95% CI 0.53 to 0.81), improved HIV testing uptake (1.11, 95% CI 1.07 to 1.15) and promoted participant retention (1.03, 95% CI 1.00 to 1.06) among key populations. The Grading of Recommendations Assessment, Development and Evaluation system showed that trails were of moderate quality.

CONCLUSIONS

This review provides evidence that SNS can reach key populations who are currently not being reached by existing programmes and deliver HIV interventions through social networks, which decreases HIV sexual risk behaviour and HIV incidence and increases HIV testing uptake and participant retention.
