Discrimination, acculturative stress, alcohol use and their associations with alcohol-related consequences among Latino immigrant men.

Latino immigrant men are at increased risk for unhealthy alcohol use and related consequences due to social stressors associated with immigration. We assessed the associations of, and examined whether social stressors moderated associations between, alcohol use and alcohol-related consequences in a community-based sample of Latino immigrant men in Washington (N = 187). The mean Alcohol Use Disorders Identification Test Consumption (AUDIT-C) score was 6.3 (scores ≥ 4 indicate unhealthy alcohol use). More than half of the men (61.5%) reported experiencing discrimination in at least one setting and mean acculturative stress score was 18.3 indicating moderate levels of acculturative stress. Linear regression models were fit to assess main effects (associations between both alcohol use and social stressors and alcohol-related consequences) and moderation (whether the association between alcohol use and consequences varied based on experience of social stressors using multiplicative interaction) after adjustment for potential confounders. Alcohol use (ß = 0.47, 95% CI = 0.20-0.73; p = .001), discrimination (ß = 0.85, 95% CI = 0.27-1.43; p = .004), and acculturative stress (ß = 0.13, 95% CI = 0.02-0.24; p = .025) were all associated with increased experience of alcohol-related consequences. The association between alcohol use and alcohol-related consequences was stronger for those with high levels of acculturative stress (p = .025) but not experience of discrimination (p = .587). Findings underscore the importance of social and cultural context in alcohol use and related consequences. Efforts to reduce negative consequences of drinking may include focus on reducing exposure to discrimination and acculturative stress.

Impact of Abstinence and of Reducing Illicit Drug Use Without Abstinence on Human Immunodeficiency Virus Viral Load.

BACKGROUND: Substance use is common among people living with human immunodeficiency virus (PLWH) and a barrier to achieving viral suppression. Among PLWH who report illicit drug use, we evaluated associations between HIV viral load (VL) and reduced use of illicit opioids, methamphetamine/crystal, cocaine/crack, and marijuana, regardless of whether or not abstinence was achieved. METHODS: This was a longitudinal cohort study of PLWH from 7 HIV clinics or 4 clinical studies. We used joint longitudinal and survival models to examine the impact of decreasing drug use and of abstinence for each drug on viral suppression. We repeated analyses using linear mixed models to examine associations between change in frequency of drug use and VL. RESULTS: The number of PLWH who were using each drug at baseline ranged from n = 568 (illicit opioids) to n = 4272 (marijuana). Abstinence was associated with higher odds of viral suppression (odds ratio [OR], 1.4-2.2) and lower relative VL (ranging from 21% to 42% by drug) for all 4 drug categories. Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with VL suppression (OR, 2.2, 1.6, respectively). Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with lower relative VL (47%, 38%, respectively). CONCLUSIONS: Abstinence was associated with viral suppression. In addition, reducing use of illicit opioids or methamphetamine/crystal, even without abstinence, was also associated with viral suppression. Our findings highlight the impact of reducing substance use, even when abstinence is not achieved, and the potential benefits of medications, behavioral interventions, and harm-reduction interventions.

Participant engagement in a community based participatory research study to reduce alcohol use among Latino immigrant men.

Although Latino immigrant men experience many health disparities, they are underrepresented in research to understand and address disparities. Community Based Participatory Research (CBPR) has been identified to encourage participant engagement and increase representation in health disparities research. The CBPR conceptual model describes how partnership processes and study design impact participant engagement in research. Using this model, we sought to describe how these domains influenced participant engagement in a pilot randomized controlled trial of brief intervention for unhealthy alcohol use (n = 121) among Latino immigrant men. We conducted interviews with a sample of study participants (n = 25) and reviewed logs maintained by 'promotores'. We identified facilitators of participant engagement, including the relevance of the study topic, alignment with participants' goals to improve their lives, partnerships with study staff that treated participants respectfully and offered access to resources. Further, men reported that the study time and location were convenient and that they appreciated being compensated for their time. Barriers to participant engagement included survey questions that were difficult to understand and competing demands of work responsibilities. Findings suggest that engaging underserved communities requires culturally responsive and community engagement strategies that promote trust. Future studies should further investigate how CBPR partnership processes can inform intervention research.

Contextual compatibility of three empirically supported behavior therapies for cART adherence among patients with substance use disorders.

Though substance use disorders complicate adherence to combination antiretroviral therapy (cART), cognitive-behavioral therapy (CBT), contingency management (CM), and motivational interviewing (MI) each demonstrate efficacy to improve cART adherence among substance-using patients. To inform dissemination of these therapies, this mixed-method study was undertaken involving a full-day site visit to each of four HIV care settings. At each setting, an initial administrator interview elicited setting data. Paired focus groups with setting staff and patients then served as forums for open discussion and live polling of the therapies' respective contextual compatibility. Focus group recordings were subjected to a phenomenological narrative analysis by multidisciplinary investigators, and staff/patient compatibility ratings were analyzed via generalized linear models. Findings include: (1) emergent themes among staff of adaptability, patient-centeredness, and mission-congruence as desired therapy attributes, (2) emergent themes among patients of intrinsic motivation, respect for patient autonomy in illness management, and fairness among service recipients as desired therapy attributes; and (3) comparatively stronger staff perception of compatibility for MI than CBT or CM, and a similar albeit less robust or reliable pattern among patients. Collective findings support MI as a behavior therapy of choice for broad dissemination to HIV care settings to improve cART adherence of patients with substance use disorders.

Impacts of an opioid overdose prevention intervention delivered subsequent to acute care.

BACKGROUND: Opioid overdose is a major and increasing cause of injury and death. There is an urgent need for interventions to reduce overdose events among high-risk persons. METHODS: Adults at elevated risk for opioid overdose involving heroin or pharmaceutical opioids who had been cared for in an emergency department (ED) were randomised to overdose education combined with a brief behavioural intervention and take-home naloxone or usual care. Outcomes included: (1) time to first opioid overdose-related event resulting in medical attention or death using competing risks survival analysis; and (2) ED visit and hospitalisation rates, using negative binomial regression and adjusting for time at risk. RESULTS: During the follow-up period, 24% of the 241 participants had at least one overdose event, 85% had one or more ED visits and 55% had at least one hospitalisation, with no significant differences between intervention and comparison groups. The instantaneous risk of an overdose event was not significantly lower for the intervention group (sub-HR: 0.83; 95% CI 0.49 to 1.40). DISCUSSION: These null findings may be due in part to the severity of the population in terms of housing insecurity (70% impermanently housed), drug use, unemployment and acute healthcare issues. Given the high overdose and healthcare utilisation rates, more intensive interventions, such as direct referral and provision of housing and opioid agonist treatment medications, may be necessary to have a substantial impact on opioid overdoses for this high-acuity population in acute care settings.

Substance Use Research with Indigenous Communities: Exploring and Extending Foundational Principles of Community Psychology.

Many Indigenous communities are concerned with substance use (SU) problems and eager to advance effective solutions for their prevention and treatment. Yet these communities also are concerned about the perpetuation of colonizing, disorder-focused, stigmatizing approaches to mental health, and social narratives related to SU problems. Foundational principles of community psychology-ecological perspectives, empowerment, sociocultural competence, community inclusion and partnership, and reflective practice-provide useful frameworks for informing ethical community-based research pertaining to SU problems conducted with and by Indigenous communities. These principles are explored and extended for Indigenous community contexts through themes generated from seven collaborative studies focused on understanding, preventing, and treating SU problems. These studies are generated from research teams working with Indigenous communities across the United States and Canada-inclusive of urban, rural, and reservation/reserve populations as well as adult and youth participants. Shared themes indicate that Indigenous SU research reflects community psychology principles, as an outgrowth of research agendas and processes that are increasingly guided by Indigenous communities. At the same time, this research challenges these principles in important ways pertaining to Indigenous-settler relations and Indigenous-specific considerations. We discuss these challenges and recommend greater synergy between community psychology and Indigenous research.

Influence of Substance Use Disorders on 2-Year HIV Care Retention in the United States.

Substance use disorders (SUDs) are thought to predict care discontinuity, though magnitude and substance-specific variance of effects are unclear. This report of analytic work undertaken with a multi-regional American cohort of 9153 care enrollees addresses these gaps. Care retention was computed from 24-month post-linkage clinic visit documentation, with SUD cases identified from patient-report screening instruments. Two generalized estimating equations tested binary and hierarchial SUD predictors of retention, and potential effect modification by patient age-group, sex, and care site. Findings demonstrate: (1) detrimental SUD effect, equivalent to a nine percentage-point decrease in retention, with independent effects of age-group and care site; (2) substance-specific effect of marijuana UD associated with lower retention; and (3) age-modification of each effect on care discontinuity, with SUDs serving as a risk factor among 18-29 year-olds and protective factor among 60+ year-olds. Collective findings document patient attributes as influences that place particular subgroups at-risk to discontinue care.

Vida PURA: An assessment of the fidelity of promotor-delivered screening and brief intervention to reduce unhealthy alcohol use among Latino day laborers.

We assessed the fidelity of promotores conducting screening and brief intervention (SBI) to reduce unhealthy alcohol use among Latino immigrant day laborers in the Vida PURA study. We reviewed 32 audio-recorded brief interventions to assess promotor adherence to the intervention protocol and to evaluate their motivational interviewing (MI) technique with the Motivational Interviewing Treatment Integrity (MITI) 4.2.1 tool. Promotores delivered three core intervention steps in 78% of recordings and achieved basic MI competence across all domains and proficiency in 50% of measures. Our results suggest that promotores can be trained to deliver SBI in community settings with fidelity.

Prevalence and Predictors of Substance Use Disorders Among HIV Care Enrollees in the United States.

Prior efforts to estimate U.S. prevalence of substance use disorders (SUDs) in HIV care have been undermined by caveats common to single-site trials. The current work reports on a cohort of 10,652 HIV-positive adults linked to care at seven sites, with available patient data including geography, demography, and risk factor indices, and with substance-specific SUDs identified via self-report instruments with validated diagnostic thresholds. Generalized estimating equations also tested patient indices as SUD predictors. Findings were: (1) a 48 % SUD prevalence rate (between-site range of 21-71 %), with 20 % of the sample evidencing polysubstance use disorder; (2) substance-specific SUD rates of 31 % for marijuana, 19 % alcohol, 13 % methamphetamine, 11 % cocaine, and 4 % opiate; and (3) emergence of younger age and male gender as robust SUD predictors. Findings suggest high rates at which SUDs occur among patients at these urban HIV care sites, detail substance-specific SUD rates, and identify at-risk patient subgroups.

Alcohol use and immune reconstitution among HIV-infected patients on antiretroviral therapy in Nairobi, Kenya.

Studies on the effects of alcohol use on HIV disease progression have been contradictory, with at least one study finding a positive effect of low alcohol consumption on CD4 count. In addition, most such studies have taken place in the developed West. We investigated the association between alcohol use and immune reconstitution through CD4 count response among HIV-infected individuals on antiretroviral therapy (ART) at an urban sub-Saharan African clinic. This was a retrospective cohort study of treatment-naïve HIV-infected adults initiating ART in Nairobi, Kenya and followed for 12 months between January 2009 and December 2012. At enrollment, a standardized questionnaire was used to collect data on sociodemographic variables and alcohol consumption. CD4 count was measured every six months. Linear regression models assessed the association between CD4 count and alcohol consumption, categorized as abstinent, moderate, or hazardous. Overall, 854 participants were included, 522 of which were women, with 85 (25.6%) men and 50 (9.6%) women reporting any alcohol use, and 8 (2.4%) men and 7 (1.3%) women reporting hazardous drinking. At baseline, alcohol use was associated with higher education and socioeconomic status. Median CD4 count was higher among alcohol users compared to those who abstained at baseline and at 6 and 12 months post-ART initiation, although this was only significant at 6 months. There were no differences in adherence between abstainers and drinkers. While overall alcohol use was significantly associated with higher CD4 counts, moderate and hazardous use treated separately were not. We conclude that, while alcohol use was associated with higher CD4 counts at 12 months post-ART, the mechanism for this association is unclear but may reflect unmeasured socioeconomic or nutritional differences. Additional research is required on the specific drinking patterns of this population and the types of alcoholic beverages consumed to clarify this relationship.

Identifying HIV care enrollees at-risk for cannabis use disorder.

Increased scientific attention given to cannabis in the United States has particular relevance for its domestic HIV care population, given that evidence exists for both cannabis as a therapeutic agent and cannabis use disorder (CUD) as a barrier to antiretroviral medication adherence. It is critical to identify relative risk for CUD among demographic subgroups of HIV patients, as this will inform detection and intervention efforts. A Center For AIDS Research Network of Integrated Clinical Systems cohort (N = 10,652) of HIV-positive adults linked to care at seven United State sites was examined for this purpose. Based on a patient-report instrument with validated diagnostic threshold for CUD, the prevalence of recent cannabis use and corresponding conditional probabilities for CUD were calculated for the aggregate sample and demographic subgroups. Generalized estimating equations then tested models directly examining patient demographic indices as predictors of CUD, while controlling for history and geography. Conditional probability of CUD among cannabis-using patients was 49%, with the highest conditional probabilities among demographic subgroups of young adults and those with non-specified sexual orientation (67-69%) and the lowest conditional probability among females and those 50+ years of age (42% apiece). Similarly, youthful age and male gender emerged as robust multivariate model predictors of CUD. In the context of increasingly lenient policies for use of cannabis as a therapeutic agent for chronic conditions like HIV/AIDS, current study findings offer needed direction in terms of specifying targeted patient groups in HIV care on whom resources for enhanced surveillance and intervention efforts will be most impactful.

USE OF COMPOSITE MATERIALS AS A COMPONENT OF TUSK FRACTURE MANAGEMENT IN AN ASIAN ELEPHANT (ELEPHAS MAXIMUS) AND AN AFRICAN ELEPHANT (LOXODONTA AFRICANA).

Tusk fractures in Asian (Elephas maximus) and African elephants (Loxodonta africana) can result in damage to the distal end or to longitudinal cracks, potentially progressing to pulpitis. With pulp exposure, endodontic therapy is the treatment of choice, but conservative therapy has sufficed for some elephants. This manuscript describes the use of composite materials as a component of tusk fracture management. A 7-yr-old male Asian elephant fractured the distal end of both tusks with pulp exposure in one. Capping of each tusk with a Kevlar/fiberglass composite prevented further damage, and a modification allowed care of the exposed pulp tissue. A 34-yr-old male African elephant with a longitudinal crack received a carbon fiber/fiberglass composite circumferential wrap to potentially stabilize the crack. Compression of the crack was achieved, but follow-up was truncated due to bacterial pulpitis. Both cases show that composite material allows for lightweight, durable management of tusk fractures with continued radiographic monitoring.

A comparison of African American and Caucasian stimulant users in 12-step facilitation treatment.

Engagement in 12-step meetings and activities has been shown to be a powerful aid to recovery from substance use disorders. However, only limited attention has been given to ethnic and racial differences in attitudes toward 12-step and involvement. This study utilized data from a large multisite trial testing the effectiveness of a 12-step facilitation therapy with stimulant-dependent treatment seekers. We compared baseline differences and treatment outcomes between African American and Caucasian participants. A select few baseline differences were found (i.e., African Americans reported higher levels of spirituality than Caucasians; African American participants indicated more perceived benefits of 12-step involvement; Caucasians were more likely to endorse future involvement in 12-step). There were no outcome differences (e.g., substance use outcomes, 12-step meeting attendance). The tested intervention produced similar outcomes for both groups, indicating that it may be useful across racial categories.

Differences in Tobacco Product Use Among Past Month Adult Marijuana Users and Nonusers: Findings From the 2003-2012 National Survey on Drug Use and Health.

INTRODUCTION: This study assessed differences in individual tobacco product use between past month marijuana users and nonusers, and trends in overall tobacco use and use of specific tobacco products among marijuana users. METHODS: Data were obtained from 378 459 adults participating in the 2003-2012 National Survey on Drug Use and Health, a cross-sectional, household interview survey conducted annually. Data from the most recent 2 years (2011-2012) were used to assess differences in the prevalence of various tobacco products by past month marijuana status. Data from all years were used to assess historical trends in overall tobacco use, and use of cigarettes, cigars, and blunts among marijuana users; trend significance was assessed using orthogonal polynomials. RESULTS: From 2011-2012, the prevalence of any past month tobacco use among the 9727 past month marijuana users was 68.6% excluding blunts, and 78.3% including blunts (vs. 25.3% for nonusers, P < .0001); 77.3% of past month marijuana users reported past month combusted tobacco use (vs. 23.4% of non-MJ users, P < .0001). By product, 60.1% of past month marijuana users reported past month cigarette use, 42.0% reported past month blunt use, and 20.6% reported past month cigar use. Overall, adjusted trends in past month cigarette use decreased, while trends in past month blunt use increased; cigar use did not change. DISCUSSION: Tobacco use is highly prevalent among adult marijuana users and represents an important potential comorbidity of marijuana use. In light of increasing policies legalizing marijuana, it is critical to monitor changes in overall and specific tobacco product use.

Decision-making processes as predictors of relapse and subsequent use in stimulant-dependent patients.

BACKGROUND: Decision-making processes have been posited to affect treatment outcome in addicted patients. OBJECTIVE: The present multi-site study assessed whether two measures of decision-making predicted relapse and subsequent use in stimulant-dependent patients. METHODS: A total of 160 methamphetamine- or cocaine-dependent patients participating in a multi-site clinical trial evaluating a modified 12-step facilitation intervention for stimulant-dependent patients (STAGE-12) were assessed. Decision-making processes of risk and delay (Iowa Gambling Task [IGT]) and response reversal (Wisconsin Card Sorting Task [WCST]) were obtained shortly after treatment admission followed by assessment of stimulant use over the next six months. The relationships of the IGT and WCST (Perseverative Errors) with relapse (yes/no) and days of stimulant use during the 6-month period following post-randomization were evaluated. RESULTS: Performance on the IGT and WCST did not significantly predict relapse status or time to relapse. Unexpectedly, worse performance on the IGT was associated with a fewer number of stimulant use days (p = 0.001). In contrast, worse performance on the WCST (more perseverative errors) was associated with a greater number of stimulant use days (p = 0.0003). The predictive effects of perseverative errors on subsequent use were confined to methamphetamine-dependent and Minority participants. CONCLUSIONS: Decision-making processes, as measured in the current study, do not uniformly predict relapse or subsequent use. A decrease in the salience attribution of non-drug reinforcers may explain the positive relationship between IGT performance and post-relapse use. More comprehensive and global measures of impulsiveness may better assess relapse risk and use.

Are medical marijuana users different from recreational users? The view from primary care.

BACKGROUND AND OBJECTIVES: Marijuana is currently approved for medical use in 23 states. Both clinicians and the lay public have questioned whether users of marijuana for medical purposes are different from users of marijuana for recreational purposes. This study examined similarities and differences in important clinical characteristics between users of medical marijuana and users of recreational marijuana. METHODS: The sample consisted of 868 adult primary care patients in Washington State, who reported use of medical marijuana (n = 131), recreational marijuana (n = 525), or drugs other than marijuana (n = 212). Retention was over 87% at 3-, 6-, 9-, and 12-month assessments. RESULTS: The majority of medical, psychiatric, substance use, and service utilization characteristic comparisons were not significant. However, medical marijuana users had significantly more medical problems, a significantly larger proportion reported >15 days medical problems in the past month, and significantly smaller proportions reported no pain and no mobility limitations (p < .001). Medical marijuana users also had significantly lower drug problem severity, lower alcohol problem severity, and significantly larger proportions reported using marijuana alone and concomitant opioid use only (p < .001). There was no significant difference between medical and recreational users in the percentage using marijuana with at least two additional substances (48% vs. 58%, respectively, p = .05). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Although our results suggest that there are few distinct differences between medical and recreational users of marijuana, the differences observed, while mostly very small in effect size (<.2), are consistent with at least some medical users employing marijuana to relieve symptoms and distress associated with medical illness.

Comparing kept appointment rates when calls are made by physicians versus behavior health technicians in inner city hospital: literature review and cost considerations.

Dropping out of scheduled care leads to medication non adherence, increased morbidity, relapse and readmission rates. As part of a performance improvement project to increase attendance rates at our outpatient clinic, psychiatric residents and Behavioral Health Technicians made reminder telephone calls under similar circumstances. We compared follow up appointment rates in the two groups. Our analysis showed that there was no significant difference in the rates of kept appointment overall between the two groups. The important finding is physician time could be better spent in other patient care duties and reminder calls could be delegated to other health staff.

Community perspectives on drug/alcohol use, concerns, needs, and resources in four Washington State Tribal communities.

Community-university teams investigated substance use, abuse, and dependence (SUAD) and related concerns, needs, strengths, and resources in four Washington State Tribal communities. A total of 153 key community members shared their perspectives through 43 semi-structured interviews and 19 semi-structured focus groups. Qualitative data analysis revealed robust themes: prescription medications and alcohol were perceived as most prevalent and concerning; family and peer influences and emotional distress were prominent perceived risk factors; and SUAD intervention resources varied across communities. Findings may guide future research and the development of much needed strength-based, culturally appropriate, and effective SUAD interventions for American Indians, Alaska Natives, and their communities.

Brief intervention for problem drug use in safety-net primary care settings: a randomized clinical trial.

IMPORTANCE: Although brief intervention is effective for reducing problem alcohol use, few data exist on its effectiveness for reducing problem drug use, a common issue in disadvantaged populations seeking care in safety-net medical settings (hospitals and community health clinics serving low-income patients with limited or no insurance). OBJECTIVE: To determine whether brief intervention improves drug use outcomes compared with enhanced care as usual. DESIGN, SETTING, AND PARTICIPANTS: A randomized clinical trial with blinded assessments at baseline and at 3, 6, 9, and 12 months conducted in 7 safety-net primary care clinics in Washington State. Of 1621 eligible patients reporting any problem drug use in the past 90 days, 868 consented and were randomized between April 2009 and September 2012. Follow-up participation was more than 87% at all points. INTERVENTIONS: Participants received a single brief intervention using motivational interviewing, a handout and list of substance abuse resources, and an attempted 10-minute telephone booster within 2 weeks (n = 435) or enhanced care as usual, which included a handout and list of substance abuse resources (n = 433). MAIN OUTCOMES AND MEASURES: The primary outcomes were self-reported days of problem drug use in the past 30 days and Addiction Severity Index-Lite (ASI) Drug Use composite score. Secondary outcomes were admission to substance abuse treatment; ASI composite scores for medical, psychiatric, social, and legal domains; emergency department and inpatient hospital admissions, arrests, mortality, and human immunodeficiency virus risk behavior. RESULTS: Mean days used of the most common problem drug at baseline were 14.40 (SD, 11.29) (brief intervention) and 13.25 (SD, 10.69) (enhanced care as usual); at 3 months postintervention, means were 11.87 (SD, 12.13) (brief intervention) and 9.84 (SD, 10.64) (enhanced care as usual) and not significantly different (difference in differences, ß = 0.89 [95% CI, -0.49 to 2.26]). Mean ASI Drug Use composite score at baseline was 0.11 (SD, 0.10) (brief intervention) and 0.11 (SD, 0.10) (enhanced care as usual) and at 3 months was 0.10 (SD, 0.09) (brief intervention) and 0.09 (SD, 0.09) (enhanced care as usual) and not significantly different (difference in differences, ß = 0.008 [95% CI, -0.006 to 0.021]). During the 12 months following intervention, no significant treatment differences were found for either variable. No significant differences were found for secondary outcomes. CONCLUSIONS AND RELEVANCE: A one-time brief intervention with attempted telephone booster had no effect on drug use in patients seen in safety-net primary care settings. This finding suggests a need for caution in promoting widespread adoption of this intervention for drug use in primary care. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00877331.

Student peer mentoring: Feasibility and acceptability of mHealth-based tool for alcohol and substance abuse prevention by peer mentors at a university in Kenya.

OBJECTIVE: The use of mobile health (mHealth)-based interventions for the prevention of alcohol and other psychoactive substances use is an emerging practice for which new evidence is required. This study evaluated the feasibility and acceptability of a mHealth-based peer mentoring tool for early screening, brief intervention, and referral of students who abuse alcohol and other psychoactive substances. It compared the implementation of a mHealth-delivered intervention to the paper-based practice that is the standard at the University of Nairobi. METHODS: A quasi-experimental study using purposive sampling was used to select a cohort of n = 100 (51 experimental, 49 control) first-year student peer mentors on two campuses of the University of Nairobi in Kenya. Data were collected on the mentors' sociodemographic characteristics as well as the feasibility and acceptability of the interventions by way of, the magnitude of reach, feedback to investigators, referral of cases, and perceived ease of use. RESULTS: The mHealth-based peer mentoring tool scored high with 100% of users rating it as feasible and acceptable. Among the two study cohorts, there were no differences in the acceptability of the peer mentoring intervention. When comparing the feasibility of the peer mentoring practice, actual use of the interventions, and intervention reach, the mHealth-based cohort mentored four mentees for every one mentored by the standard practice cohort. CONCLUSION: The mHealth-based peer mentoring tool had high feasibility and acceptability among student peer mentors. The intervention provided evidence for the need to expand the availability of screening services for alcohol and other psychoactive substances use among students in the university and promote the appropriate management practices within and outside the university.
