Outcomes of substance use and sexual power among adolescent girls and young women in Cape Town: Implications for structural and cultural differences.

Adolescent girls and young women (AGYW) in South Africa experience contextual barriers to HIV risk reduction including incomplete schooling, unintended pregnancy, substance use, and gender-based violence. A cluster randomised trial in Cape Town allocated 24 Black and Coloured communities to a gender-focused HIV risk-reduction intervention or HIV testing, with 500 AGYW total enrolled. We evaluated intervention efficacy by comparing mean differences overall, by community population group (Black and Coloured) and among those with structural barriers based on neighbourhood, education, and employment (n = 406). Both arms reported reductions in alcohol, cannabis, and condomless sex, with no intervention efficacy overall. Among AGYW with barriers, intervention participants reported fewer days of methamphetamine use at 6 months (t(210) = 2·08, p = ·04). In population group analysis, we found intervention effects on alcohol and sexual communication. Intervention participants in Black communities had fewer days of alcohol use at 12 months (t(136) = 2·10, p = ·04). Sexual discussion (t(147) = -2·47, p = ·02) and condom negotiation (t(146) = -2·51, p = ·01) increased for intervention participants at 12 months in Coloured communities. Gender-focused interventions must address population group differences and intersecting barriers to decrease substance use and increase education, skills, and sexual health protection.

A Mixed-Methods Approach to Develop a Combined Model of U.S. College Student Alcohol-Associated Condomless Sex.

Unhealthy alcohol use and sexually transmitted infections (STIs) are significant public health concerns for US college students. Because alcohol use and condomless sex often co-occur in this population, alcohol-associated condomless sex has been identified as a behavioral intervention target. Existing theoretical frameworks have not garnered sufficient empirical support to serve as the foundation for interventions. The primary goal of the current study was to use a mixed-methods approach to develop a model of college student alcohol-associated condomless sex that combines elements from well-established health behavior theories. In Aim 1, multilevel modeling was used to predict condomless vaginal sex in a sample of heterosexual college student drinkers (N = 53). Aim 2 consisted of in-depth interviews (n = 18) to gather perceptions about the role of alcohol in sexual activity and identify supplemental constructs omitted from theories in Aim 1. The multilevel model explained a significant proportion of variance in condomless vaginal sex at the between- and within-person level. Themes derived from the in-depth interviews identified complementary elements of condom use decision-making. Findings from both aims were synthesized to construct a combined model of alcohol-associated condomless sex. This model can be further refined and ultimately serve as the foundation of an alcohol-STI prevention-intervention.

Development of a risk estimation model for condomless sex among college students in Zhuhai, China: a cross-sectional study.

BACKGROUND: Condom use at last intercourse is an effective indicator for human immunodeficiency virus (HIV) prevention. To identify at-risk individuals and improve prevention strategies, this study explored factors associated with condomless sex at last intercourse in the last year and developed a risk estimation model to calculate the individual possibility of condomless sex among college students in Zhuhai, China. METHODS: A cross-sectional study was conducted among 1430 college students who had sex in the last year from six universities in Zhuhai. The least absolute shrinkage and selection operator (LASSO) and logistic regression were performed to explore the predictors of condomless sex. The nomogram was constructed to calculate the individual possibility of condomless sex. Discrimination and calibration of the nomogram were evaluated using the area under the receiver-operator characteristic curve (AUROC) and the calibration curve. RESULTS: The proportion of students who had condomless sex at last intercourse was 18.2% (260/1430). Students who had experienced more types of intimate partner violence (aOR, 1.58; 95% CI, 1.31 ~ 1.92) and had anal sex (aOR, 1.75; 95% CI, 1.06 ~ 2.84) were more likely to have condomless sex. Students who had heterosexual intercourse (aOR, 0.37; 95% CI, 0.21 ~ 0.70), used condoms at first sex (aOR, 0.20; 95% CI, 0.14 ~ 0.27), had high attitudes towards condom use (aOR, 0.87; 95% CI, 0.80 ~ 0.95) and self-efficacy for condom use (aOR, 0.84; 95% CI, 0.78 ~ 0.90) were less likely to have condomless sex. The nomogram had high accuracy with an AUROC of 0.83 and good discrimination. CONCLUSIONS: Intimate partner violence, anal sex, condom use at first sex, attitude towards condom use, and self-efficacy for condom use were associated with condomless sex among college students. The nomogram was an effective and convenient tool for calculating the individualized possibility of condomless sex among college students. It could help to identify individuals at risk and help universities and colleges to formulate appropriate individualized interventions and sexual health education programs.

Validity of Partner Reports of Recent Condomless Sex.

BACKGROUND: Prostate-specific antigen (PSA), a biomarker of vaginal semen exposure, is less susceptible to bias than self-reported condom use behaviors. We examined the agreement of self-reported recent condomless sex (RCS) within couples and how these reports related to PSA detection. METHODS: We analyzed data from a study conducted in Vietnam, 2017 to 2020, of 500 different-sex couples using condoms and no other contraceptive method to prevent pregnancy for 6 months. We assessed enrollment and 6-month data from vaginal swabs and questionnaires from both partners. We calculated Prevalence-Adjusted Bias-Adjusted Kappa (PABAK) to evaluate agreement of men's and women's reports. Among couples with detected PSA, we assessed partner concordance of RCS reporting. RESULTS: At enrollment (n = 499), 79.8% of couples reported no RCS, 16.4% reported RCS, and 3.8% had partner-discordant reports (PABAK, 0.93; 95% confidence interval, 0.91-0.97). At 6 months (n = 472), 91.7% reported no RCS, 5.7% reported RCS, and 2.5% had partner-discordant reports (PABAK, 0.98; 95% confidence interval, 0.96-1.0). Among couples with detected PSA at baseline (11%, n = 55), 36% reported no RCS, 55% reported RCS, and 6% had discordant reports; at 6 months (6.6%, n = 31), 58% reported no RCS, 35% reported RCS, and 3% had discordant reports. CONCLUSIONS: We observed high agreement regarding condomless sex within couples in a population using condoms as contraception in Vietnam; however, a high proportion of couples with detected PSA had both partners reporting no RCS, indicating that concordant reporting of no RCS does not indicate lack of semen exposure.

Characteristics Associated with Pre-Exposure Prophylaxis Discussion and Use Among Transgender Women Without HIV Infection - National HIV Behavioral Surveillance Among Transgender Women, Seven Urban Areas, United States, 2019-2020.

CDC recommends pre-exposure prophylaxis (PrEP) for transgender women who have sex with men and who report sexual behaviors that place them at substantial ongoing risk for HIV exposure, including those who engage in nonsterile syringe sharing. Providing transgender women with access to PrEP is a critical strategy for reducing HIV acquisition and ending the HIV epidemic. Survey results from the National HIV Behavioral Surveillance Among Transgender Women were used to assess characteristics associated with past-year discussions of PrEP with a health care provider and PrEP use. Bivariate analyses were conducted to assess the association between covariates (sociodemographic, HIV-associated characteristics, and gender-affirming care) and each outcome, accounting for sampling design. All covariates that were statistically significant at p<0.05 in the bivariate analyses were included in multivariate models, and manual backward elimination was used to obtain final models that retained statistically significant covariates. Among 902 transgender women from seven urban areas in the United States without HIV infection in the analyses, 57% had recently discussed PrEP with a health care provider, and 32% recently had used PrEP. In the final multivariate model, the following subgroups of transgender women were more likely to report recent PrEP use: those who identified as Black or African American or Hispanic or Latina, had two or more sex partners in the past 12 months, had condomless sex in the past 12 months, reported their last sex partner was infected with HIV, had condomless sex with their last sex partner whose HIV status was positive or unknown, ever had transgender-specific health care, and currently had transgender-specific health insurance coverage. Participants who were less likely to have recently used PrEP were those who wanted to but were not currently taking hormones and those aged <40 years. Providing increased access to gender-affirming care and training health care providers who serve transgender women to incorporate PrEP into existing services might increase PrEP use among transgender women.

Pampalibog: chemsex, desire and pleasure in the Philippines.

This article draws from qualitative interviews to provide the first in-depth exploration of reasons for engaging in chemsex in the Philippines. It articulates the many forms that drugs assume as pampalibog, or enhancers of libido, demonstrating the multidimensional pleasures of chemsex along overlapping sensorial and affective planes. By showing the inextricability of the corporeal to the affective, and of the emotional to the erotic, we contend that chemsex also involves the embodied and performed attainment of pleasure. As such, chemsex is both central to modern sexual scripts yet also a negotiable aspect of any sexual encounter. In constructing this rare account of drug use in settings of pleasure in the Philippines, we situate chemsex within a historical pattern of bodily tinkering and, more significantly, demystify people who use drugs by departing not only from global public health's pathologising approach to chemsex, but also from the scholarly tendency to locate drug use in the country within scenes of hardship and marginalisation.

Substance use, economic vulnerability, and HIV/STI risk among female sex workers in Mexico.

BACKGROUND: Economic hardship (e.g., difficulty to pay for basic needs) has been associated with increased HIV/STI risk among female sex workers (FSW), and may be exacerbated by high levels of substance use. Few studies have assessed the intersection of economic hardship, substance use, and HIV/STI risk among FSW. METHODS: Quantitative data were collected via questionnaires among 469 FSW residing in Tijuana and Ciudad Juarez, Mexico. Using logistic regression, we assessed the role of economic hardship on the association between substance use (past 30-days alcohol use, drug use, or injection drugs use with clients, and past 6-months drug use) and testing positive for an STI (also an indicator of HIV risk). RESULTS: Drug use in the preceding six months was significantly associated with testing positive for an STI (AOR = 1.8, CI: 1.1 = 2.9, p = .02); no difference in this association was found by whether women reported economic hardship. Past 30-day drug use with clients was associated with STI infection, but only among those who did not report economic hardship (AOR = 1.5, 95% CI: 1.1-1.9, p < .01). CONCLUSIONS: Findings suggest that economic hardship influences the association between substance use and increased risk for HIV/STI among FSW; however, these associations may be more complex than previously hypothesized.

A Comparison of Self-reported Condomless Sex and Yc-DNA Biomarker Data from Young Women Engaged in High Risk Sexual Activity in Kampala, Uganda.

Reporting of condom-use can limit researchers' understanding of high-risk sexual behaviours. We compared self-reported condom-use with the Yc-DNA biomarker data and investigated potential factors influencing participation in, and reporting of, sexual behaviours. Self-reported data were collected using Audio Computer Assisted Self Interviews (ACASI) and samples for Yc-DNA biomarker were collected using self-administered and health worker-collected vaginal swabs from 644 women (aged 15-24 years) who were not living with HIV. Yc-DNA results and interview data were compared using McNemar-Bowker Analysis and Cohen's Kappa. Test statistics for Yc-DNA biomarker were calculated. Log Binomial models for Yc-DNA and self-reported results were conducted to assess for association. We found strong evidence (p < 0.001) for a difference between Yc-DNA and self-reported results. 13.7% of participants reported consistent condom-use with all partners, regardless of HIV status. Self-reported condom-use was discordant in 50.0% (n = 206) of cases, when compared to Yc-DNA results. Positive Yc-DNA results were found to be associated with older age (RR 1.36; 95%CI 1.04, 1.76 p = 0.023). Self-reported condom-use with partners with unknown HIV status was associated with higher education (RR 0.76; 95%CI 0.58,0.99 p = 0.043). Sensitivity analysis did not determine difference between methods for controlling for missing data. We found significant under-reporting of condomless sex in the self-reported data when compared to Yc-DNA results.

Doxycycline Prophylaxis to Prevent Sexually Transmitted Infections in Women.

BACKGROUND: Doxycycline postexposure prophylaxis (PEP) has been shown to prevent sexually transmitted infections (STIs) among cisgender men and transgender women, but data from trials involving cisgender women are lacking. METHODS: We conducted a randomized, open-label trial comparing doxycycline PEP (doxycycline hyclate, 200 mg taken within 72 hours after condomless sex) with standard care among Kenyan women 18 to 30 years of age who were receiving preexposure prophylaxis against human immunodeficiency virus (HIV). The primary end point was any incident infection with Chlamydia trachomatis, Neisseria gonorrhoeae, or Treponema pallidum. Hair samples were collected quarterly for objective assessment of doxycycline use. RESULTS: A total of 449 participants underwent randomization; 224 were assigned to the doxycycline-PEP group and 225 to the standard-care group. Participants were followed quarterly over 12 months. A total of 109 incident STIs occurred (50 in the doxycycline-PEP group [25.1 per 100 person-years] and 59 in the standard-care group [29.0 per 100 person-years]), with no significant between-group difference in incidence (relative risk, 0.88; 95% confidence interval [CI], 0.60 to 1.29; P = 0.51). Among the 109 incident STIs, chlamydia accounted for 85 (78.0%) (35 in the doxycycline-PEP group and 50 in the standard-care group; relative risk, 0.73; 95% CI, 0.47 to 1.13). No serious adverse events were considered by the trial investigators to be related to doxycycline, and there were no incident HIV infections. Among 50 randomly selected participants in the doxycycline-PEP group, doxycycline was detected in 58 of 200 hair samples (29.0%). All N. gonorrhoeae-positive isolates were resistant to doxycycline. CONCLUSIONS: Among cisgender women, the incidence of STIs was not significantly lower with doxycycline PEP than with standard care. According to hair-sample analysis, the use of doxycycline PEP among those assigned to receive it was low. (Funded by the National Institutes of Health; dPEP ClinicalTrials.gov number, NCT04050540.).

Conclusión: las variables estudiadas indicaron que hay una fuerte relación entre las parejas estables y el aumento de la confianza y la baja adherencia al uso del preservativo, lo que coincide con otros estudios.

Objective: to analyze the factors associated with inconsistent use of male condoms among HIV-negative men who have sex with other men. Method: a cross-sectional, analytical and nationwide study conducted online in all the Brazilian regions in 2020, via networks and in dating websites. Inconsistent condom use was defined as occasional use or as never using it. Descriptive statistical analyses were performed, as well as association and binary logistic regression tests. Results: inconsistent condom use was reported by 1,222 (85%) of all 1,438 participants. The "homosexuals" (ORAdj: 2.03; 95% CI: 1.14-3.59; p=0.016), "having a fixed partner" (ORAdj: 2.19; 95% CI: 1.55-3.09; p<0.001), "oral sex" (ORAdj: 2.41; 95% CI: 1.31-4.43; p=0.005), "insertive anal" (ORAdj: 1.98; 95% CI: 1.10-3.58; p=0.023) and "STI diagnosis" (ORAdj: 1.59; 95% CI: 1.13-2.24; p=0.007) variables were independently associated with inconsistent use of male condoms. The "receiving advice on HIV test from a friend" (ORAdj: 0.71; 95% CI: 0.52-0.96; p=0.028) and "sex worker" (ORAdj: 0.26; 95% CI: 0.11-0.60; p=0.002) variables were protective factors. Conclusion: the variables under study pointed to a strong relationship between steady partners and increased trust and low adherence to condom use, corroborating other studies.

Understanding the dynamics of chemsex among men who have sex with men, male sex workers and transgender women in Dhaka, Bangladesh: a multiphase sequential mixed-method research protocol.

INTRODUCTION: Chemsex is defined as drug use to enhance sexual pleasure. Global literature illustrated the pervasiveness of chemsex among men who have sex with men (MSM) and transgender women (hijra) for prolonging anal intercourse, reducing pain and intensifying pleasure, oftentimes without condoms. Global literature highlighted the association between chemsex and unsafe sexual behaviours. These circumstances warrant targeted chemsex research to explore the chemsex situation. The study aims to explore the overall dynamics of chemsex among MSM, male sex workers (MSW) and hijra in Dhaka, Bangladesh and formulate culturally relevant, context-specific, gender-sensitive and evidence-based recommendations for chemsex interventions. METHODS AND ANALYSIS: This will be a sequential, exploratory, mixed-methods study. Data will be collected at four drop-in centres in Dhaka in three phases. To explore issues related to chemsex, the formative phase (phase 1) will generate evidence on the overall dynamics of chemsex through a literature review and qualitative interviews. Qualitative data will be manually analysed using thematic analysis. In phase 2, a cross-sectional survey will be conducted among 458 MSM, male sex workers and hijra to measure the prevalence, reasons and sexual risk behaviour associated with chemsex. In phase 3, qualitative interviews will be conducted with the participants involved in chemsex, service providers and relevant stakeholders to add qualitative depth to survey responses. In this phase, service provision will also be investigated for people engaging in chemsex. Moreover, based on the findings of phases 1 and 2, and qualitative interviews of phase 3, a preliminary chemsex intervention model will be developed through a series of intervention design workshops. ETHICS AND DISSEMINATION: Ethical approval has been attained from the Ethical Review Committee of icddr,b. Informed consent will be obtained from the participants, and confidentiality will be maintained during data collection and storage. Findings will be disseminated via several platforms including dissemination seminars, scientific articles and study report.

Does the Quality of Behavior Change Counseling in Routine HIV Care Vary According to Topic and Demand?

HIV clinicians face increasing time constraints. Our objective was to describe the prevalence and quality of behavior change counseling within routine HIV visits and to explore whether clinicians may provide lower quality counseling when facing increased counseling demands. We audio-recorded and transcribed encounters between 205 patients and 12 clinicians at an urban HIV primary care clinic. We identified and coded episodes of behavior change counseling to determine clinicians' consistency with motivational interviewing (MI) and used multi-level regression to evaluate counseling quality changes with each additional topic. Clinician counseling for at least one behavior was indicated in 92% of visits (mean 2.5/visit). Behavioral topics included antiretroviral medication adherence (80%, n = 163), appointment adherence (54%, n = 110), drug use (46%, n = 95), tobacco use (45%, n = 93), unsafe sex (43%, n = 89), weight management (39%, n = 80), and alcohol use (35%, n = 71). Clinician counseling was most MI-consistent when discussing drug and tobacco use and least consistent for medication and appointment adherence, unsafe sex, and alcohol use. In multilevel analyses, clinician counseling was significantly less MI-consistent (ß = - 0.14, 95% CI - 0.29 to - 0.001) with each additional behavior change counseling need. This suggests that HIV ambulatory care be restructured to allocate increased time for patients with greater need for behavior change.

Sexual risk-taking behavior amongst emerging adults in a tertiary institution of learning in Coastal Kenya: A qualitative study of stakeholders' perspectives using causal loop mapping.

BACKGROUND: It is known from previous studies that university students in sub-Saharan Africa (sSA) engage in sexual risk-taking behaviour (SRTB). However, there is paucity of data on factors contributing to SRTB among university students (emerging adults) at the Kenyan Coast thus hindering intervention planning. This study seeks to provide an in-depth qualitative understanding of the factors contributing to SRTB and their interconnectedness among university students at the Kenyan Coast combining qualitative research with a systems thinking approach. METHODS: Using the ecological model, and employing in-depth interviews, we explored the perceptions of twenty-six key informants (twenty-one emerging adults and five other stakeholders) on what constitutes and influences SRTB among emerging adults at a tertiary institution of learning in Coastal Kenya. Data were analysed using a thematic framework approach. A causal loop diagram (CLD) was developed to map the interconnectedness of the correlates of SRTB. RESULTS: Our findings show that unprotected sex, transactional sex, cross-generational sex, multiple sex partnerships, gender-based violence, sex under influence of alcohol/drugs, early sex debut, and sharing sex toys were common SRTBs. Based on the ecological model and CLD, most of the reported risk factors were interconnected and operated at the individual level. CONCLUSION: Our study shows that emerging adults are frequently engaging in unprotected sex. Enhancing sexuality education programs for students in Kenyan universities and strengthening support systems including counselling for those using alcohol/drugs may help reduce SRTB among emerging adults in Kenyan universities.

Global disease burden attributed to unsafe sex in 204 countries and territories from 1990 to 2019: results from the Global Burden of Disease Study 2019.

Unsafe sex has become a public safety problem that endangers society, and research on deaths and disability-adjusted life years (DALYs) related to unsafe sex is valuable for global policy-making. We aimed to estimate the deaths and DALYs attributable to unsafe sex by country, gender, age group, and sociodemographic status from 1990 to 2019. We extracted data on disease burden from the Global Disease Burden 2019 (GBD 2019) database for unsafe sex, including deaths, DALYs and age-standardized rates (ASRs). Comparative analyses were performed on data about deaths, DALYs and the responding ASRs attributable to unsafe sex in different countries and regions using the Social Demographic Index (SDI). The global age-standardized mortality rate (ASMR) and age-standardized DALY rate (ASDR) attributable to unsafe sex were 11.98 (95% uncertainty intervals (UI): 10.97-13.52) per 100,000 people and 570.78 (95% UI: 510.24-658.10) per 100,000 people, respectively. Both the ASMRs and ASDRs were the highest in southern sub-Saharan Africa and lowest in Australasia and decreased with increasing SDI levels. About unsafe-sex-related disease, HIV/AIDS has the highest ASMR [8.48 (95% UI: 7.62-9.95)/100,000 people] and ASDR [447.44 (95% UI: 394.82-533.10)/100,000 people], followed by Cervical cancer [ASMR: 3.40 (95% UI: 2.90-3.81)/100,000 people and ASDR: 107.2 (95% UI: 90.52-119.43)/100,000 people] and sexually transmitted infections excluding HIV [ASMR: 0.10 (95% UI: 0.08-0.11)/100,000 people and ASDR: 16.14 (95% UI: 10.51-25.83)/100,000 people]. The death and DALY burden caused by these three diseases were more serious in the over 75 years old age group. The 40-44 age group for men and the 35-39 age group for women had the highest population of unsafe sex-related deaths and DALYs, respectively. In addition, the burden of unsafe sex in women was more serious than those in men. Unsafe sex is an important risk factor for global disease burden and a leading cause of substantial health loss. We found that the risk of ASMRs and ASDRs attributable to unsafe sex had negative correlation with SDI levels. These results demonstrate that the need for revised policies that focus on efforts to reduce overall unsafe sex worldwide.

Sexualised drug use and chemsex in Italy: A questionnaire study based on a cohort of clients attending a STI outpatient service in Milan.

BACKGROUND: Chemsex is a heterogeneous phenomenon with differences in distribution, setting, motivations and type of substances consumed between countries. The lack of data at national level of the Italian situation creates a perception of reduced need for intervention. METHODS: Anonymous paper questionnaires were distributed to patients who had registered themselves at the STI Department IRCCS Ca' Granda Policlinico in Milan. RESULTS: A significant association was demonstrated between use of sexualised drugs, chemsex and the following variables: (1). Number of partners: in the group of clients with more than five partners, sexualised drug users were more than twice compared with those in the group with less than five partners (35.2% vs 16.2%) p<0.0001. (2). Use of dating apps: more than one out of two persons who used drugs during sex affirmed looking for partners on internet, p = 0.0059. (3). Low condom uses with occasional partners: percentage of individuals who declared not to use condoms or devices during their sexual encounters with occasional partners is more than twice as high in the sexualised drug users group with respect to controls (44.6% vs 21.4%); p = 0.0006). (4). Use of post exposure prophylaxis (PEP): among the PEP users, more than half participants belonged to the sexualised drug users' group; p = 0.0021. CONCLUSIONS: Sexualised drug use and chemsex are frequently practiced in Milan. This survey identified a specific population with higher-risk sexual behaviours and increased incidence of acute bacterial STIs.

Effectiveness of Youth Risk Prevention Programs When Virtually Adapted.

PURPOSE: COVID-19 forced many youth risk prevention programs to be adapted to virtual formats. It remains unclear whether virtual programming is as effective as in-person programming. This study examined program logistics, differences in reach of at-risk youth and risk reduction in a youth substance use prevention program before and after being adapted to a virtual platform due to COVID-19. METHODS: Rural high school students in a substance use prevention program completed baseline and follow-up surveys. Data were included from two program cohorts, one in 2020 (In-person; N = 331) and the second in 2021 (virtual; N = 426). Survey data were analyzed to compare differences between cohorts in ability to reach at-risk youth and effects on risk reduction. Data on program logistics were drawn from open-ended facilitator questionnaires and site observation reports. These data were analyzed to understand benefits and challenges with virtual program implementation. RESULTS: In-person participants were older, in a higher grade, and reported higher rates of substance abuse, reported higher rates of substance use, sexual behaviors, and risky sex. Virtual program participants reported higher rates of unprotected sex and future intentions of unprotected sex. Neither program showed significant reduction in risk intermediary factors. Positive attitudes about the benefits of substance use increased during the virtual program. Thematic analysis revealed problems with implementing the virtual program, including low attendance and technology issues. DISCUSSION: In-person programs moved to virtual delivery may be less effective at reaching at-risk youth, may have smaller impact on risk prevention and may encounter logistical problems. Because previous research has found that technology-based interventions can be effective, future research should seek to evaluate how to strengthen evidence-based practices when delivery modality changes.

Does Binge-Watching eHealth Intervention Content Impact Outcomes?

PURPOSE: Advancements in technology have made it possible to deliver parenting interventions online, known as eHealth interventions. Little is known about the rate at which parents participate in eHealth interventions, characteristics of parents who watch eHealth interventions at an accelerated pace (i.e., binge-watching), and if binge-watching impacts intervention outcomes. METHODS: The sample included 142 Hispanic parents who were randomly assigned to an eHealth family-based intervention and completed 100% of eight online, prerecorded and self-paced video group sessions delivered across 12 weeks. We examined baseline predictors (parent sociodemographic characteristics, report of child's externalizing behaviors, and family functioning) of watching group sessions in two weeks or less (n = 23, 16.2%). Using latent growth curve modeling, we tested the impact of binge-watching on the trajectory of adolescent drug use, condomless sex, and depressive symptoms across 36 months. We also examined the impact of binge-watching on changes in family functioning from baseline to 6 months postbaseline. RESULTS: Parents with high levels of education and of children with attention problems were more likely to binge-watch. Conversely, parents of children with conduct disorder symptoms were less likely to binge-watch. The trajectory of depressive symptoms increased for adolescents with parents who binge-watched the intervention, but the trajectory of condomless sex decreased. There was no impact on drug use. Binge-watching was also associated with decreases in parental monitoring. DISCUSSION: The findings of this study have implications for eHealth interventions; the pace that parents watch eHealth interventions may subsequently impact adolescent outcomes, such as condomless sex and depressive symptoms.

Predicting Response to Services for Homeless Adolescents and Transition Age Youth (TAY) with Substance Use And/Or Mental Health Disorders: Implications for Youth Treatment and Recovery.

PURPOSE: This paper examines patterns of response to a multi-disciplinary wrap-around program for homeless adolescents and transition-aged youth with substance use and/or mental health disorders. METHOD: A cluster analysis of outcome data from 148 youth was conducted. RESULTS: Cluster 1 (n = 67) demonstrated significant decreases in risky behavior (e.g., engaging in unprotected sex, crime, and substance use) and poor interpersonal relationships (e.g. more interaction with family and friends and lower rates of violence) but experienced relatively fewer interactions with family and friends. Cluster 2 (n = 57) demonstrated a significant decrease in poor life functioning (e.g., lower rates of employment/education, better quality of life, and less symptoms of internalizing disorders). Cluster 3 (n = 24) experienced significant increases in risky behavior, poor life functioning, and poor interpersonal relationships. DISCUSSION: Clusters 1 and 2 improved over six months of care. Cluster 3 deteriorated despite receiving similar services and used more opioids and stimulants. CONCLUSIONS: Peer engagement in programs for this population are important. Recommendations for cluster 3 include targeted outreach, medication assisted treatment, and additional research-supported treatments. Further research is needed to test these interventions over longer periods of time.

Reactions to Testing HIV Negative: An Assessment of Measurement Invariance and Associations with Condomless Anal Sex among English and Spanish-speaking Latinx Sexual Minority Men in the United States.

Among the many effective prevention strategies, frequent HIV testing continues to be promoted to reduce the risk of HIV transmission among sexual minority men (SMM). Testing negative for HIV can result in varied reactions that influence subsequent HIV transmission behaviors, yet the extant research has primarily been conducted in English. The current study examined measurement invariance of a Spanish-translated Inventory of Reactions to Testing HIV Negative (IRTHN). The study also examined whether the IRTHN was associated with subsequent condomless anal sex. Data were drawn from 2,170 Latinx SMM subsample of the UNITE Cohort Study. We conducted a multigroup confirmatory factor analysis to test for measurement invariance between participants who opted to take the survey in English (n = 2,024) and those who opted to take it in Spanish (n = 128). We also examined if the IRTHN is associated with subsequent CAS. The results were suggestive of partial invariance. The subscales of Luck and Invulernability were associated with CAS at the 12-month follow-up. Practice and research-based implications are discussed.
