Refining a Novel Measure of Polysubstance Use
BACKGROUND: Cognitive interviewing is a methodological technique to elicit feedback on item comprehension and response categories by the target population. This method can be particularly relevant when working with vulnerable populations, such as people who use drugs, and for complex behaviors, including the use of multiple drugs (i.e., polysubstance use). While cognitive interviewing is recognized as an important technique, few case studies of t…
People Who Use Illegal Opioids Use of Methadone over Time, and What Characteristics Are Correlated with Staying in Methadone Maintenance Treatment
INTRODUCTION: Methadone maintenance treatment (MMT) is among the best strategies for reducing harms associated with illegal opioid use, yet it is hindered by low rates of treatment initiation and retention that limit its impact. There has been a lack of studies that describe how people who use illegal opioids use methadone-both from opioid treatment programs, and bought illegally-over time, or what factors correlate with long-term participation i…
“It’s Our Superpower”
African American/Black and Latine (AABL) emerging adults living with HIV have insufficient engagement along the HIV care continuum, and lower rates than their White peers. Some subpopulations (e.g., those with unsuppressed HIV viral load, immigrants) and aspects of their experiences are understudied. This study uses a sequential explanatory mixed-methods design to explore motivational appraisals (e.g., core health goals), generative capabilities …
Development and Validation of a Provider-Specific Anticipated Stigma Scale for People Who Inject Drugs
Stigma in healthcare settings is a critical barrier to HIV prevention and treatment among people who inject drugs (PWID). While previous tools have measured anticipated stigma, few account for the intersectional and provider-specific experiences of PWID-particularly from syringe service programs (SSPs). We developed and validated the Substance Use Anticipated Provider Stigma Scale (SU-APSS), a multidimensional instrument assessing anticipated sti…
Black and Latinx Foreign- and US-Born Young and Emerging Adults Living with HIV
Police Harassment and Psychiatric, Sexual, and Substance Use Risk Among Black Sexual Minority Men and Black Transgender Women in the HIV Prevention Trials 061 Cohort
Social processes and engagement along the HIV care continuum
Racial/ethnic and age-related disparities in HIV care continuum engagement are serious in the US. American/Black and Latine (AABL) young/emerging adults living with HIV have the lowest rates of engagement, but aspects of their experiences and some subpopulations are understudied. The present study is grounded in social action theory and uses a sequential explanatory mixed methods design to explore social interaction processes (e.g., social networ…

An Examination of How People Who Use Drugs Conceptualize the Benefits and Drawbacks of Using Overdose Prevention Centers
Background: In 2021, NYC implemented overdose prevention center (OPC) services at two existing syringe exchange programs, allowing people to use pre-obtained drugs on-site. Although OPCs in Canada, Western Europe, and Australia have demonstrated their feasibility and benefits towards reducing overdose risk and drug-related harm, there is less data on how people who use drugs (PWUD) conceptualize the benefits and any potential drawbacks of using O…
Utility of self-report antiretroviral adherence for predicting HIV viral load among persons who inject drugs in Hai Phong Vietnam
In resource-limited settings, alternatives to HIV viral load testing may be necessary to monitor the health of people living with HIV. We assessed the utility of self-report antiretroviral therapy (ART) to screen for HIV viral load among persons who inject drugs in Hai Phong Vietnam, and consider differences by recent methamphetamine use. From 2016 to 2018 we recruited PWID through cross sectional surveys and collected self-report ART adherence a…

Empirical Development of a Behavioral Intervention for African American/Black and Latino Persons with Unsuppressed HIV Viral Load Levels
A virtual pilot optimization trial for African American/Black and Latino persons with non-suppressed HIV viral load grounded in motivational interviewing and behavioral economics
Introduction: Virtual and low-touch behavioral interventions are needed for African American/Black and Latino persons living with HIV (PLWH) with barriers to HIV viral suppression, particularly during COVID-19. Guided by the multiphase optimization strategy, we explored three components for PLWH without viral suppression, grounded in motivational interviewing and behavioral economics: (1) motivational interviewing counseling, (2) 21-weeks of auto…
Age Differences in the Associations Between Incarceration and Subsequent Substance Use, Sexual Risk-Taking, and Incident STI Among Black Sexual Minority Men and Black Transgender Women in the HIV Prev…
Incarceration can lead to different risk behaviors often due to increased distress and disruption of social networks. It is not well known, however, how these associations may differ by age. In this study, we measure age differences in longitudinal associations between incarceration and substance use, sex risk, and sexually transmitted infection (STI) among Black sexual minority men and Black transgender women (BSMM/BTW). We recruited BSMM/BTW fr…
Exploring behavioral intervention components for African American/Black and Latino persons living with HIV with non-suppressed HIV viral load in the United States
The present study advances research on interventions for African American/Black and Latino PLWH, who experience complex barriers to engagement along the HIV care continuum. Future study of the components is warranted to address racial/ethnic health inequities in HIV
Understanding why racial/ethnic inequities along the HIV care continuum persist in the United States
To reduce racial/ethnic inequities and end the HIV epidemic, it is necessary to understand African American/Black and Latino PLWH's perspectives on the systemic impediments they experience throughout the HIV care continuum. This study uncovers and describes a number of salient barriers and how they operate, including unexpected findings regarding drug diversion and negative aspects of congregate housing. There is growing awareness that systemic r…

Posttraumatic stress disorder symptoms and incarceration
Black men and people belonging to sexual minority groups are disproportionately impacted by criminal legal involvement and sexually transmitted infections (STIs). Traumatic experiences are often associated with later criminal legal involvement, depression symptoms, sexual risk behavior, and STIs. Research on the joint influence of trauma and incarceration on STI risk among racial and/or sexual minority people is limited. This study tested the ass…
The association between discrimination and the health of Sikh Asian Indians
Consistent with previous discrimination and health reports, this study demonstrated an inverse relationship between discrimination and health among Sikh AIs, an understudied yet high-risk minority population. Community-based efforts are also needed to reduce the occurrence or buffer the effects of discrimination experienced by Sikh AIs. (PsycINFO Database Record
Longitudinal Associations Between Adolescent Alcohol Use and Adulthood Sexual Risk Behavior and Sexually Transmitted Infection in the United States
Objectives. We examined race differences in the longitudinal associations between adolescent alcohol use and adulthood sexually transmitted infection (STI) risk in the United States. Methods. We estimated multivariable logistic regression models using Waves I (1994–1995: adolescence) and III (2001–2002: young adulthood) of the National Longitudinal Study of Adolescent Health (n = 10 783) to estimate associations and assess differences between Whi…

A comparison of self-reported sexual effects of alcohol, marijuana, and ecstasy in a sample of young adult nightlife attendees
Alcohol, marijuana, and ecstasy (3,4-methylenedioxymethamphetamine [MDMA], 'Molly') are among the most prevalent substances used by young adults; however, few studies have focused on the specific sexual effects associated with use. Examining subjective sexual effects (e.g. increased libido) associated with use can inform prevention efforts. Data were analysed from 679 nightclub and dance festival attendees in New York City (ages 18-25) to examine…
Contextual Predictors of Injection Drug Use Among Black Adolescents and Adults in US Metropolitan Areas, 1993–2007
Objectives. We sought to determine whether contextual factors shape injection drug use among Black adolescents and adults. Methods. For this longitudinal study of 95 US metropolitan statistical areas (MSAs), we drew annual MSA-specific estimates of the prevalence of injection drug use (IDU) among Black adolescents and adults in 1993 through 2007 from 3 surveillance databases. We used existing administrative data to measure MSA-level socioeconomic…
Drug Arrests and Injection Drug Deterrence
Objectives. We tested the hypothesis that higher rates of previous hard drug–related arrests predict lower rates of injection drug use. Methods. We analyzed drug-related arrest data from the Federal Bureau of Investigation's Uniform Crime Reporting Program for 93 large US metropolitan statistical areas in 1992 to 2002 to predict previously published annual estimates of the number of injection drug users (IDUs) per 10 000 population.

Detecting Latent Taxa
A Monte Carlo evaluation of four procedures for detecting taxonicity was conducted using artificial data sets that were either taxonic or nontaxonic. The data sets were analyzed using two of Meehl's taxometric procedures, MAXCOV and MAMBAC, Ward's method for cluster analysis in concert with the cubic clustering criterion and a latent variable mixture modeling technique. Performance of the taxometric procedures and latent variable mixture modeling…
Taxometric Analysis of Fuzzy Categories
A small Monte Carlo study examined the performance of a form of taxometric analysis (the MAXCOV procedure) with fuzzy data sets. These combine taxonic (categorical) and nontaxonic (continuous) features, containing a subset of casts with intermediate degrees of category membership. Fuzzy data sets tended to yield taxonic findings on plot inspection and two popular consistency tests, even when the degree of fuzziness, i.e., the proportion of interm…
Predictors of Retention in Dual-Focus Self-Help Groups
The Effect of 12-Step-Based Fellowship Participation on Abstinence Among Dually Diagnosed Persons
A large percentage of individuals are dually-diagnosed with a psychiatric disorder and a substance use disorder. Such persons typically face more difficulties and have poorer outcomes than do single disorder substance users. Among noncomorbid substance users, treatment and participation in 12-Step groups have been shown to enhance the likelihood of abstinence from substance misuse. Specialized 12-Step based fellowships have recently emerged to ad…

The Combined Effects of Treatment Intensity, Self-Help Groups and Patient Attributes on Drinking Outcomes
Better understanding of the diverse factors that predict alcoholism treatment outcomes is essential to improving treatment strategies. Patients accepted for treatment at a multimodality program were interviewed and followed-up at three months and one year after admission. The study tested a set of hypotheses relating to the effects on drinking outcomes of treatment modality, modality matching, treatment retention, aftercare, self-help group parti…
The Impact of Syringe Deregulation on Sources of Syringes for Injection Drug Users
HIV risk behaviors among female IDUs in developing and transitional countries
Gender differences in risk depend on the relational contexts in which risk behaviors occur. The fact that female and male risk behavior often occurs in different relational contexts suggests that different kinds of prevention interventions which are sensitive to these contexts may be necessary
Behavioral interventions for HIV infected and uninfected mothers with problem drinking
This article evaluates the efficacy of a 14-session social-cognitive behavioral intervention on problem drinking (and where applicable, drug use) among urban HIV-infected and uninfected mothers, in comparison to a single-session social/motivational intervention, and explores the relationships of initial substance use problem severity and HIV status to efficacy. A randomized controlled trial design was used. Participants (N = 118) were mothers wit…
