Pharmacy nonprescription syringe distribution and HIV/AIDS: A review

Patrick Janulis

OBJECTIVE To summarize current research findings on pharmacy nonprescription syringe distribution to prevent the spread of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) among injection drug users (IDUs), including research on pharmacist attitudes and behavior, drug user attitudes and behavior, and the health impact on HIV/AIDS risk behavior. DATA SOURCES Data were collected using PubMed and PsycINFO through July 2011. Search terms used were pharmacist or pharmacy and syringe or syringe exchange or needle or needle exchange. Two journals (Journal of Urban Health and Journal of the American Pharmacists Association) with a high number of hits were manually inspected. Reference sections for each article also were examined. STUDY SELECTION Studies were included if they examined attitudes toward, experiences with, or the impact of pharmacy nonprescription syringe distribution for the purpose of preventing the spread of HIV/AIDS among IDUs in the United States. Studies were excluded that mentioned these topics in passing or did not report empirical results. DATA SYNTHESIS 47 studies were identified that met the inclusion criteria. Studies included a diverse range of perspectives, including pharmacist viewpoints, IDU attitudes, and evaluations. CONCLUSION According to the available literature, many pharmacists express willingness to sell and report selling syringes to customers without a prescription. IDUs show willingness to use pharmacies to obtain syringes. Finally, pharmacy syringe sale and the legalization of this practice appear to have a positive impact on HIV risk behavior. Accordingly, the nonprescription sale of syringe should be promoted. However, the literature remains incomplete and future research is required.

While much social network data exists online, key network metrics for high-risk populations must still be captured through self-report. This practice has suffered from numerous limitations in workflow and response burden. However, advances in technology, network drawing libraries and databases are making interactive network drawing increasingly feasible. We describe the translation of an analog-based technique for capturing personal networks into a digital framework termed netCanvas that addresses many existing shortcomings such as: 1) complex data entry; 2) extensive interviewer intervention and field setup; 3) difficulties in data reuse; and 4) a lack of dynamic visualizations. We test this implementation within a health behavior study of a high-risk and difficult-to-reach population. We provide a within--subjects comparison between paper and touchscreens. We assert that touchscreen-based social network capture is now a viable alternative for highly sensitive data and social network data entry tasks.

The micro-social risk environment for injection drug use: An event specific analysis of dyadic, situational, and network predictors of injection risk behavior

Patrick Janulis

BACKGROUND This study explores the risk environment for drug use by examining injection risk behavior during specific injection episodes. By leveraging multiple observations of injection episodes of participants, the study attempts to move beyond global assessment of environmental variables to simultaneously model within (i.e., event level) as well as between (i.e., individual level) predictors of injection risk. Furthermore, gender is also explored as a potential moderator of the relationship between the association of specific partner characteristics (e.g., having an injection partner who is also a sexual partner) and injection risk behavior. METHODS Data is used from the Sexual Acquisition of Transmission of HIV Cooperative Agreement Study (SATHCAP). Multilevel structural equation modeling is utilized to predict within and between variations in underlying injection risk behavior as measured using four indicators of injection risk. RESULTS Results indicated that a number of partner level characteristics (i.e., being emotionally close with the partner, sexual partnership, being a first time partner) and one social situational (i.e., the number of non-injectors present at the injection episode) characteristic predicted event level injection risk behavior. However, the impact of partner characteristics also appears to be moderated by gender of the participants. More specifically, sharing a sexual partnership with an injection partner was more strongly associated with injection risk among females as compared to males and females indicated higher levels of risk when injecting with other females while the partners gender showed no significant association with risk for male injectors. CONCLUSION These results suggest that people who inject drug do report varying levels of risk during different injection episodes and this variation can be explained by partner and situational characteristics. Improved understanding of the social processes surrounding injection episodes is required to further refine harm reduction approaches.

The differences between direct ties (i.e., ties between a respondent and their nominees) and ties between nominees (indirect) are key to understanding network structure, yet remain understudied. Within a sample of 175 young men who have sex with men, we explored the corroboration of sex and drug ties, and factors associated with corroboration. The majority of instances in which there was no corroboration for either sex or drug ties was due to one individual not appearing in another respondents network. When an individual did appear in another respondents network, direct sex and drug ties were corroborated in most cases. We also found that more indirect sex ties were corroborated than direct sex ties (95.7% vs. 88.9%), but the reverse was true for indirect versus direct drug ties (73.1% vs. 84.1%). Strength of relationship and frequency of communication were both associated with confirmed direct ties, but not with indirect ties. Based on these findings, we recommend that direct and indirect ties be treated differently in network analyses.

HIV Prevention Fatigue and HIV Treatment Optimism Among Young Men Who Have Sex With Men

Kathryn Macapagal; Michelle Birkett; Patrick Janulis; Robert Garofalo; Brian Mustanski

HIV prevention fatigue (the sense that prevention messages are tiresome) and being overly optimistic about HIV treatments are hypothesized to increase HIV risk behavior. Little research has examined these constructs and their correlates among young men who have sex with men (YMSM), who are at high risk for HIV. YMSM (N = 352; Mage = 20; 50% Black) completed measures of prevention fatigue, treatment optimism, HIV risk behaviors, and HIV-related knowledge and attitudes during a longitudinal study. Overall, YMSM reported low levels of HIV prevention fatigue and treatment optimism. Path analysis (n = 307) indicated that greater prevention fatigue and treatment optimism predicted higher rates of condomless sex, but condomless sex did not predict later increases in prevention fatigue or treatment optimism. Results are inconsistent with the hypothesis of high prevention fatigue and treatment optimism among YMSM and point to potential causal relationships among these variables and condomless sex.

Re-Evaluating Sexual Violence Prevention Through Bystander Education: A Latent Growth Curve Approach

Jessica Shaw; Patrick Janulis

Recently, there has been a call for more advanced analytic techniques in violence against women research, particularly in community interventions that use longitudinal designs. The current study re-evaluates experimental evaluation data from a sexual violence bystander intervention program. Using an exploratory latent growth curve approach, we were able to model the longitudinal growth trajectories of individual participants over the course of the entire study. Although the results largely confirm the original evaluation findings, the latent growth curve approach better fits the demands of “messy” data (e.g., missing data, varying number of time points per participant, and unequal time spacing within and between participants) that are frequently obtained during a community-based intervention. The benefits of modern statistical techniques to practitioners and researchers in the field of sexual violence prevention, and violence against women more generally, are further discussed.

Improving measurement of injection drug risk behavior using item response theory.

Patrick Janulis

Abstract Background: Recent research highlights the multiple steps to preparing and injecting drugs and the resultant viral threats faced by drug users. This research suggests that more sensitive measurement of injection drug HIV risk behavior is required. In addition, growing evidence suggests there are gender differences in injection risk behavior. However, the potential for differential item functioning between genders has not been explored. Objectives: To explore item response theory as an improved measurement modeling technique that provides empirically justified scaling of injection risk behavior and to examine for potential gender-based differential item functioning. Methods: Data is used from three studies in the National Institute on Drug Abuse’s Criminal Justice Drug Abuse Treatment Studies. A two-parameter item response theory model was used to scale injection risk behavior and logistic regression was used to examine for differential item functioning. Results: Item fit statistics suggest that item response theory can be used to scale injection risk behavior and these models can provide more sensitive estimates of risk behavior. Additionally, gender-based differential item functioning is present in the current data. Conclusion: Improved measurement of injection risk behavior using item response theory should be encouraged as these models provide increased congruence between construct measurement and the complexity of injection-related HIV risk. Suggestions are made to further improve injection risk behavior measurement. Furthermore, results suggest direct comparisons of composite scores between males and females may be misleading and future work should account for differential item functioning before comparing levels of injection risk behavior.

Multiple Minority Stress and LGBT Community Resilience Among Sexual Minority Men.

Minority stress theory has widespread empirical support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research that examines macrolevel processes such as community resilience is needed (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i.e., racial–ethnic stigma in LGBT spaces and LGBT stigma in one’s neighborhood) and community resilience (i.e., connection to LGBT community) among sexual minority men of different racial–ethnic groups who use a geosocial networking application for meeting sexual partners. Results showed that Black sexual minority men reported the highest levels of racial–ethnic stigma in LGBT spaces and that White sexual minority men reported the lowest levels, with Asian and Hispanic–Latino men falling in between. Consistent with minority stress theory, racial–ethnic stigma in LGBT spaces and LGBT stigma in one’s neighborhood were associated with greater stress for sexual minority men of all racial–ethnic groups. However, connection to LGBT community played a more central role in mediating the relationship between stigma and stress for White than POC sexual minority men. Results suggest that minority stress and community resilience processes may differ for White and POC sexual minority men. Potential processes driving these differences and implications for minority stress theory are discussed.

Substance use network characteristics and drug and alcohol use behaviors among young men who have sex with men (YMSM)

Patrick Janulis; Michelle Birkett; Gregory Phillips; Brian Mustanski

BACKGROUND Young men who have sex with men (YMSM) use alcohol and other drugs at rates higher than their heterosexual peers. While social networks of YMSM have been acknowledged as an important contextual influence on their health behavior, studies have largely focused on social and sexual networks rather than substance use networks, despite the potential importance of substance use alters in shaping substance use behavior. METHOD Using data collected from a diverse sample of YMSM (n=156), two multilevel models examined the associations between network (e.g., degree and transitivity), dyadic (e.g., strength of relationship), and individual characteristics and two alter level dependent variables: recent drug use (versus no recent drug use) and frequency of substance use. RESULTS Results indicated that transitivity was associated with both recent drug use (OR=1.21, p=0.012) and more frequent substance use (b=0.08, p=0.002). Degree was not significantly associated with either variable. Furthermore, participants were also less likely to have recently used drugs (OR=0.93, p<0.001) and tended to use substances less frequently (b=-0.01, p=0.028) with older alters. CONCLUSIONS Despite substantial interest in network influences on health, much remains unknown about the impact of network structures on substance use. The current findings suggest that structural characteristics of substance use networks may provide important information regarding the drug and alcohol use behavior of YMSM even when controlling for dyadic and individual characteristics.

Predictors of correspondence between self-reported substance use and urinalysis screening among a racially diverse cohort of young men who have sex with men and transgender women

Dennis H. Li; Patrick Janulis; Brian Mustanski

It is unknown if estimates of illicit drug use among young men who have sex with men and transgender women (YMSM/TW) may be biased due to historical distrust of research or reliable due to more accepting norms for use. Research is needed to examine the validity of drug use self-reports among YMSM/TW. Data came from an ongoing longitudinal study of YMSM/TW aged 16-29 living in Chicago (analytic N = 1029). Baseline urinalysis screens for marijuana, ecstasy, amphetamine, methamphetamine, cocaine, benzodiazepine, and opiate metabolites were compared to self-reported use within different recall periods using measures of concordance. Generalized estimating equations logistic regressions were conducted on three waves of data to identify predictors of disclosing past-6-month use of marijuana and non-marijuana drugs. Past-6-month self-reported use of all non-marijuana substances was <15%. There was excellent agreement between self-reported and drug-tested marijuana use. For other substances, sensitivities within the urinalysis detection window were <0.5 but increased with longer recall periods. Black participants had lower odds of disclosing non-marijuana drug use. Gender minority participants had lower odds of disclosing marijuana use. Participants with a history of arrest had higher odds of disclosing both marijuana and non-marijuana drug use. Wave and year of first research participation were non-significant, suggesting no systematic bias or increasing honesty associated with longer research participation. Programs that rely on self-identification of non-marijuana illicit substance use may be missing a substantial portion of drug-using YMSM/TW. Future epidemiological studies should work to reduce social desirability biases and include biomarker-based drug screenings to increase validity.
