Recruiting drug-using men who have sex with men into behavioral interventions: a two-stage approach

Integration of an Electronic Screening, Brief Intervention, and Referral to Treatment Program Into an HIV Testing Program to Reduce Substance Use and HIV Risk Behavior Among Men Who Have Sex With Men: Protocol for Intervention Development and a Pilot Randomized Controlled Trial

BACKGROUND

Men who have sex with men (MSM) are disproportionally affected by HIV and drug and alcohol use; however, few effective HIV prevention interventions for MSM who use substances exist. Screening, Brief Intervention, and Referral to Treatment is an early intervention for non-treatment-seeking individuals with problematic substance use and for timely referral to treatment for those with substance use disorders. Electronic screening and brief interventions (e-SBIs) reduce implementation challenges. An e-SBI tailored for MSM at the time of HIV testing might be particularly opportune to strengthen their motivation to reduce substance use and HIV risk behavior.

OBJECTIVE

This study aims to develop a tailored e-SBI program to reduce substance use and HIV risk behavior among MSM seeking HIV testing at Nexo Asociación Civil, our community partners in Argentina (primary); assess the feasibility and acceptability of integrating the e-SBI into the Nexo HIV testing program (primary); assess the feasibility and acceptability of implementing an adapted Men's Health Project (MHP) at Nexo (secondary); and finally, explore preliminary findings on substance use and sexual risk reduction outcomes (exploratory).

METHODS

This mixed methods study has 2 stages. During stage 1 (development), we will use the User Centered Rapid App Design process consisting of focus groups (n=16), individual interviews (n=24), and a pilot deployment of the e-SBI (n=50) to iteratively develop the e-SBI. Quantitative and qualitative assessments at each step will inform the revision of the e-SBI. Furthermore, we will use the assessment, decision, administration, production, topic experts, integration, training, testing framework to adapt MHP. During stage 2 (pilot randomized controlled trial [RCT]), we will randomize 200 MSM coming to Nexo for HIV testing. They will complete a baseline assessment and then their assigned intervention (e-SBI vs screening only) and will be followed-up for 6 months. We will also conduct in-depth interviews with up to 45 participants: 15 participants from either study condition who entered or completed MHP or other substance abuse treatment and 15 from each arm who met the criteria for MHP but did not request it.

RESULTS

The study began recruitment in October 2022, and the stage-1 pilot study is near completion. Preliminary findings from stage 1 show high e-SBI acceptability. Data analysis of the stage-1 pilot is now beginning. The stage-2 pilot RCT will be launched in March 2024, with all data collection completed by May 2025.

CONCLUSIONS

This study will allow us to assess the acceptability and feasibility of e-SBI implementation during HIV testing encounters. We will also build the necessary research infrastructure for a subsequent RCT to assess the efficacy of e-SBIs in reducing substance use and HIV sexual risk behavior among MSM in this setting.

Randomized Controlled Trial of Rise, A Community-Based Culturally Congruent Counseling Intervention to Support Antiretroviral Therapy Adherence Among Black/African American Adults Living with HIV

Structural inequities have led to HIV disparities, including relatively low antiretroviral therapy adherence and viral suppression rates among Black Americans living with HIV. We conducted a randomized controlled trial of Rise, a community-based culturally congruent adherence intervention, from January 2018 to December 2021 with 166 (85 intervention, 81 control) Black adults living with HIV in Los Angeles County, California [M (SD) = 49.0 (12.2) years-old; 76% male]. The intervention included one-on-one counseling sessions using basic Motivational Interviewing style to problem solve about adherence, as well as referrals to address unmet needs for social determinants of health (e.g., housing services, food assistance). Assessments included electronically monitored adherence; HIV viral load; and baseline, 7-month follow-up, and 13-month follow-up surveys of sociodemographic characteristics, HIV stigma, medical mistrust, and HIV-serostatus disclosure. Repeated-measures intention-to-treat regressions indicated that Rise led to significantly (two-fold) higher adherence likelihood, lower HIV stigmatizing beliefs, and reduced HIV-related medical mistrust. Effects on HIV viral suppression, internalized stigma, and disclosure were non-significant. Moreover, Rise was cost-effective based on established standards: The estimated cost per person to reach optimal adherence was $335 per 10% increase in adherence. Interventions like Rise, that are culturally tailored to the needs of Black populations, may be optimal for Black Americans living with HIV (ClinicalTrials.gov #NCT03331978).

Using a 2-stage strategy with respondent-driven sampling to recruit a hard-to-reach population for a placebo microbicide gel clinical trial in Nellore, Andhra Pradesh (India)

Traditional recruitment methods for microbicide efficacy trials are labor intensive and may fail to reach high-risk hard-to-reach populations. We report duration of recruitment and lessons learned from a two-stage process to recruit female sex workers (FSWs) into a placebo microbicide trial, and examined characteristics associated with successful recruitment of peers who screened for and enrolled in the trial. FSWs were first recruited via respondent-driven sampling (RDS) to complete a survey and subsequently invited to screen for enrollment into a placebo microbicide trial taking place at a local clinic. It took 6 months to enroll 267 participants into the trial. Successful recruiters of peers who enrolled were more likely to have enrolled themselves (AOR 2.0, CI 1.3-2.9) and less likely to visit Nellore city (AOR 0.5, CI 0.3-0.9). Recruitment of FSWs via a two-stage recruitment strategy with RDS can be a good option for future clinical trials.

Recruiting drug using men who have sex with men in behavioral intervention trials: a comparison of internet and field-based strategies

Although online and field-based samples of men who have sex with men (MSM) have been compared on a variety of markers, differences in drug use have not been well examined. In addition, generalization from studies comparing recruitment methods is often limited by a focus on either HIV seropositive or seronegative MSM. We compared two New York City-based samples of MSM recruited simultaneously between July 2009 and January 2010-one sample recruited in the field (n = 2,402) and one sample recruited via the Internet (n = 694). All recruitment efforts targeted men without restriction on age or self-reported HIV status. Our results show marked differences in drug and alcohol use between online and field-based samples of MSM. Specifically, men surveyed online were significantly more likely to have tried a variety of drugs, including methamphetamine, cocaine, and ecstasy. Men recruited online were also more likely to report older age, HIV positive serostatus, and "never" using condoms. Internet-based recruitment was found to be more cost-effective in terms of recruitment yield than was field-based recruitment.

Motivational interviewing for substance abuse

BACKGROUND

There are 76.3 million people with alcohol use disorders worldwide and 15.3 million with drug use disorders. Motivational interviewing (MI) is a client-centred, semi-directive method for enhancing intrinsic motivation to change by exploring and resolving ambivalence. The intervention is used widely, and therefore it is important to find out whether it helps, harms or is ineffective.

OBJECTIVES

To assess the effectiveness of motivational interviewing for substance abuse on drug use, retention in treatment, readiness to change, and number of repeat convictions.

SEARCH STRATEGY

We searched 18 electronic databases, 5 web sites, 4 mailing lists, and reference lists from included studies and reviews. Search dates were November 30, 2010 for Cochrane Library, Medline, Embase and PsychINFO.

SELECTION CRITERIA

Randomized controlled trials with persons dependent or abusing substance. Interventions were MI or motivational enhancement therapy. The outcomes were extent of substance abuse, retention in treatment, motivation for change, repeat conviction.

DATA COLLECTION AND ANALYSIS

Three authors independently assessed studies for inclusion, and two authors extracted data. Results were categorized into (1) MI versus no-treatment control, (2) MI versus treatment as usual, (3) MI versus assessment and feedback, and (4) MI versus other active treatment. Within each category, we computed meta-analyses separately for post-intervention, short, medium and long follow-ups.

MAIN RESULTS

We included 59 studies with a total of 13,342 participants. Compared to no treatment control MI showed a significant effect on substance use which was strongest at post-intervention SMD 0.79, (95% CI 0.48 to 1.09) and weaker at short SMD 0.17 (95% CI 0.09 to 0.26], and medium follow-up SMD 0.15 (95% CI 0.04 to 0.25]). For long follow-up, the effect was not significant SMD 0.06 (95% CI-0.16 to 0.28). There were no significant differences between MI and treatment as usual for either follow-up post-intervention, short and medium follow up. MI did better than assessment and feedback for medium follow-up SMD 0.38 (95% CI 0.10 to 0.66). For short follow-up, there was no significant effect . For other active intervention there were no significant effects for either follow-up.There was not enough data to conclude about effects of MI on the secondary outcomes.

AUTHORS' CONCLUSIONS

MI can reduce the extent of substance abuse compared to no intervention. The evidence is mostly of low quality, so further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

Recruiting hard-to-reach drug-using men who have sex with men into an intervention study: lessons learned and implications for applied research

Drug (ab)use researchers and service providers across the globe have been challenged with locating target populations and subsequently enrolling participants into their programs. This study presents data from nearly 3 years (2004-2006) of recruiting "high-risk" drug-using gay and bisexual men into a clinical research trial based in New York City. During the enrollment period, two recruitment/marketing strategies were utilized: (1) marketing of the intervention research study itself to men who were in the early stages of identifying problems with their drug use and risky sexual behavior and (2) two-stage recruitment via a lower-threshold/commitment (i.e., brief survey) and subsequent offering/enrollment into the full trial upon completion of the initial visit (i.e., a foot-in-the-door). The second approach was substantially more effective in enrolling participants into the full trial (6.3 participants/month vs. 2.5 participants/month). Furthermore, recruitment costs for the foot-in-the-door approach were substantially reduced ($356.57 per participant vs. $497.03 per participant). Compared to the marketing of interventions themselves to target populations, a two-stage recruitment strategy incorporating lower-threshold interactions may be a more effective approach to recruit for interventions.

Risk reduction for HIV-positive African American and Latino men with histories of childhood sexual abuse

While the HIV epidemic has disproportionately affected African American and Latino men who have sex with men (MSM), few HIV prevention interventions have focused on African American and Latino men who have sex with both men and women (MSMW). Even fewer interventions target HIV-positive African American and Latino MSM and MSMW with histories of childhood sexual abuse (CSA), a population that may be vulnerable to high-risk sexual behaviors, having multiple sexual partners, and depression. The Men's Health Project, a small randomized clinical trial, compared the effects of two 6-session interventions, the Sexual Health Intervention for Men (S-HIM), guided by social learning theory and aimed at decreasing high-risk sexual behaviors, number of sexual partners, and depressive symptoms, and a standard health promotion control (SHP). A community sample of 137 HIV-positive gay and non-gay identifying African American and Latino MSM and MSMW with histories of CSA was recruited. Results were based on an "intent to treat" analyses of baseline to post, 3 and 6 month follow-ups. The sample as a whole reported reductions in sexual risk behaviors and number of sexual partners from baseline to post-test, and from the 3 to 6 month follow-ups, although the decrease in sexual risk behavior from baseline to post-test was significant only for S-HIM participants. No significant differences between conditions were reported for depressive symptoms, but the total sample reported a significant decrease at 6 months. These findings highlight the importance of addressing sexual decision-making and psychological adjustment for ethnic men, while being sensitive to CSA histories and sexual minority status, and suggest the need to develop additional strategies to heighten HIV risk reduction over time.

The effectiveness of individual-, group-, and community-level HIV behavioral risk-reduction interventions for adult men who have sex with men: a systematic review

This article presents the results of a systematic review of the effectiveness and economic efficiency of individual-, group-, and community-level behavioral interventions intended to reduce the risk of acquiring sexually transmitted HIV in adult men who have sex with men (MSM). These results form the basis for recommendations by the Task Force on Community Preventive Services on the use of these interventions. Sexual risk behavior and condom use were the outcomes used to assess effectiveness. Intervention effectiveness on biological outcomes could not be assessed because too few studies of adequate quality have been published. The evidence found in our review shows that individual-level, group-level, and community-level HIV behavioral interventions are effective in reducing the odds of unprotected anal intercourse (range 27% to 43% decrease) and increasing the odds of condom use for the group-level approach (by 81%). The Task Force concluded that the findings are applicable to MSM aged 20 years or older, across a range of settings and populations, assuming that interventions are appropriately adapted to the needs and characteristics of the MSM population of interest. Based on findings from economic evaluation studies, the Task Force also concluded that group- and community-level HIV behavioral interventions for adult MSM are not only cost effective but also result in actual cost savings. Additional information about other effects, barriers to implementation, and research gaps is provided in this paper. The recommendations based on these systematic reviews are expected to serve the needs of researchers, planners, and other public health decision makers.

Efficacy of a behavioral intervention for increasing safer sex behaviors in HIV-positive MSM methamphetamine users: results from the EDGE study

BACKGROUND

Methamphetamine use has been associated with rising STI/HIV transmission rates, particularly among men who have sex with men (MSM). Interventions which successfully reduce risk for HIV transmission among this population are a public health priority. This study examined the efficacy of a behavioral intervention for increasing safer sex behaviors in the context of ongoing methamphetamine use in a sample of HIV-positive, methamphetamine-using MSM.

METHODS

Three-hundred and forty-one participants from San Diego, CA were randomly assigned to receive either a safer sex behavioral intervention (EDGE) or a time-equivalent diet-and-exercise attention-control condition. Random effects regression analyses were used to evaluate change in safer sex behaviors over a 12-month period.

RESULTS

Participants in the EDGE intervention engaged in significantly more protected sex acts at the 8-month (p=0.034) and 12-month assessment (p=0.007). By 12-months post-baseline, a greater percentage of protected sex acts was observed for EDGE (25.8%) vs. control participants (18.7%) (p=0.038). There was a significant time-by-intervention interaction (p=0.018) for self-efficacy for condom use, suggesting that EDGE participants' self-efficacy demonstrated a greater increase over time compared to control participants.

CONCLUSIONS

These results suggest that it is possible to reduce high risk sexual behaviors in the context of ongoing methamphetamine use among HIV-infected MSM.

Conducting nursing research with men who have sex with men: challenges and strategies for nurse researchers

The group most affected by the HIV epidemic is men who have sex with men (MSM). Since the beginning of the epidemic in 1981, this group was one the four identified high-risk groups, and MSM continue to comprise nearly 50% of all cases of HIV/AIDS. In the context of HIV infection and safer sex behaviors, this population has been the focus of numerous research studies. Despite the wealth of research that has been conducted on this population, very little information is available on research methods and strategies that nurse researchers can use to study this population. This report details one nurse researcher's experiences in gaining access to this population, unique recruitment issues, and challenges in data collection. In addition, strategies and interventions that were used by this researcher to overcome these challenges in the research process are discussed.

Associations between methamphetamine use and HIV among men who have sex with men: a model for guiding public policy

Among men who have sex with men (MSM) in Los Angeles County, methamphetamine use is associated with high rates of HIV prevalence and sexual risk behaviors. In four separate samples of MSM who differed in the range of their intensity of methamphetamine use, from levels of recreational use to chronic use to those for MSM seeking drug abuse treatment, the association between methamphetamine use and HIV infection increased as the intensity of use increased. The lowest HIV prevalence rate (23%) was observed among MSM contacted through street outreach who mentioned recent methamphetamine use, followed by MSM who used at least once a month for six months (42%), followed by MSM seeking intensive outpatient treatment (61%). The highest rate (86%) was observed among MSM seeking residential treatment for methamphetamine dependence. The interleaving nature of these epidemics calls for comprehensive strategies that address methamphetamine use and concomitant sexual behaviors that increase risk of HIV transmission in this group already at high risk. These and other data suggest that MSM who infrequently use methamphetamine may respond to lower intensity/lower cost prevention and early intervention programs while those who use the drug at dependence levels may benefit from high intensity treatment to achieve goals of reduced drug use and HIV-risk sexual behaviors.
