A Socioecological Perspective on Sexual Health Promotion Choices Among Youth At-Risk for and Living with HIV in Los Angeles and New Orleans
Youth in the US remain at high relative risk for HIV and sexually transmitted infections compared to other age groups despite increasing diversity in the available tools to reduce HIV risk through behavioral strategies, biomedical methods, and treatment as prevention. Previous research has shown that acceptability and appeal of prevention methods vary across youth, and over-emphasis on any one strategy may overlook youth’s autonomy to make their …
A livelihood intervention improved nutritional, mental health and sexual health outcomes among HIV-affected adolescents in western Kenya
INTRODUCTION: Interventions that address household-level factors, including food insecurity (FI) and poverty, may reduce HIV risk and improve sexual and reproductive health (SRH) among adolescent girls and young women (AGYW). METHODS: (SM). SM was a multisectoral agricultural livelihood intervention designed to improve HIV health. At the trial end, we used linear and logistic regressions to compare differences between the intervention and control…
Expanding the employment quality framework
Precarious employment, a condition marked by job instability, low wages, and limited protections, exacerbates economic insecurity and poor health, yet little is known about its impact on Black emerging adults (BEA). This study draws on longitudinal qualitative data to examine how young adults ages 18–24 experience and navigate precarious work while participating in a guaranteed income trial. We conducted in-depth interviews with 36 participants a…

VPs are in residence at CAPS for three summers, complete a pilot research project, and prepare National Institutes of …
Increasing Sustained Viral Suppression Among Youth Living with HIV
PrEP Disparities Among Transgender Feminine, Transgender Masculine, Nonbinary, and Gender Expansive Youth and Young Adults in the United States
This study assessed disparities in pre-exposure prophylaxis (PrEP) use among transgender and gender expansive youth and young adults (N = 477) between 15 and 24 years old in the CARES (ATN 149) and TechStep (ATN 160) study protocols within the National Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Structural equation modeling was used to test mediation pathways between gender identity and PrEP uptake among the full sample a…
Online Peer Support for Youth at Higher Risk of or Living with HIV
With the rise of technology-based interventions for HIV risk reduction among adolescents, research is needed to assess how youth participate in these strategies. We used qualitative content analysis to examine youth's posts in an online peer support intervention through the Adolescent Trials Network (ClinicalTrials.gov NCT03134833, registered May 1, 2017) for youth at higher risk of or living with HIV. We analyzed 308 posts across 85 conversation…
“We remember the pain”
Rates of homelessness among adults aged 50 and over are rising. Common strategies for exiting homelessness rely on social and family support. However, intergenerational trauma may disrupt these social support networks and contribute to homelessness. Understanding the impact of intergenerational trauma on living with family or friends may give insight into addressing homelessness among older adults. We purposefully sampled 46 adults who reported l…
Results of a Randomized Wait-List Controlled Trial of Caya
Youth experiencing homelessness (YEH) face challenges that increase their susceptibility to HIV/STIs. Nurse case management is effective in managing the complex needs of populations experiencing homelessness and reducing HIV risk. A randomized wait-list control study conducted between September 2019 to May 2023 evaluated the CAYA "Come As You Are" intervention. This nurse-led HIV prevention for YEH aged 16-25 years focused on the uptake of HIV pr…
Strategies to Facilitate Service Utilization Among Youth at Risk for HIV
Sexual and gender minority youth (SGMY) are vulnerable to acquiring HIV and need HIV prevention and health services, but may have competing needs. A prior analysis found that PrEP use reports increased in a combination intervention study arm with coaching, peer support, and automated text-messages. This paper examines ancillary support and healthcare services utilization as secondary intervention objectives. SGMY (N = 895, 40% Black, 29% Latino) …
Positive and Negative Experiences With Supportive Services and Programming
Services for youth experiencing homelessness (YEH) are designed with limited input from the youth themselves. This study explored the experiences and recommendations for services aimed at mitigating the negative effects of homelessness among youth. A total of 45 interviews were conducted with YEH (ages 15 to 24, M = 21.5 years) who experienced at least one night of homelessness. Transcripts were coded by using a modified constructivist grounded t…
Supporting Community Partners in Reducing HIV-Related Health Disparities
The HIV epidemic remains a public health threat in the U.S., and the dissemination and implementation of evidence-based prevention and care programs are critical to addressing significant HIV health disparities. The provision of technical assistance (TA) to program providers and evaluators is key for uptake of these programs. The University of California San Francisco Prevention Research Center (UCSF PRC) model for TA delivery uses topics and str…
Social Change and the Health of Sexual Minority Individuals
This study examined the extent to which social stress stemming from a stigmatized social status (i.e., minority stress) was associated with three domains of health in younger as compared with older age cohorts of sexual minority individuals. Data were analyzed from the Generations Study, a longitudinal study using a probability sample ( N = 1518) of age cohorts of sexual minority individuals in the USA. Exposure to a variety of minority stressors…
The qualitative interview in psychology and the study of social change
Interviewing is considered a key form of qualitative inquiry in psychology that yields rich data on lived experience and meaning making of life events. Interviews that contain multiple components informed by specific epistemologies have the potential to provide particularly nuanced perspectives on psychological experience. We offer a methodological model for a multi-component interview that draws upon both pragmatic and constructivist epistemolog…

Macro-level approaches to HIV prevention among ethnic minority youth
The HIV epidemic continues to disproportionately affect ethnic minority youth. These disconcerting health disparities indicate that although existing HIV preventive strategies for ethnic minority youth have been efficacious, they have not significantly reduced the impact of the epidemic in this population. Macro-level interventions, such as structural or policy interventions, have the potential to impact the HIV epidemic at a population level, an…

Who is doing well? A typology of newly homeless adolescents
There is growing evidence to support developing new typologies for homeless adolescents. Current typologies focus on the risks associated with being homeless, with less consideration of the positive attributes of homeless adolescents. The authors examined both risk and protective factors in a sample of newly homeless adolescents. Using cluster analysis techniques, they identified three distinct clusters of newly homeless adolescents: those who ar…
Individual and Environmental Protective Factors for Risky Sexual Behavior among Homeless Youth
Computerized HIV Preventive Intervention for Adolescents
We tested the hypothesis that a computerized intervention would be as efficacious as an in-person, small-group intervention in reducing sexual risk behaviors. The sexual behavior of high-risk adolescents in 3 intervention conditions was examined: (1) computer based, (2) small groups, and (3) control. Adolescents in the computerized intervention were significantly less likely to engage in sexual activity and reported significantly fewer partners. …
Aids Risk Behaviors among American and Australian Homeless Youth
We examined HIV/AIDS risk behaviors among homeless youth in cross‐national data collected in Melbourne, Australia (n= 398), and Los Angeles, California (n= 498). Using structural equation modeling, we found that the Australian youth reported greater involvement in AIDS risk behaviors than the American youth and the Australian youth were more involved in intervening risk factors that promote risk behaviors and less involved with protective factors…
Developmental, Ethnic, and Gender Differences in Ethnic Identity among Adolescents
Students' ratings of five components of ethnic identity were examined: their ethnic self-label, reference group, ethnically related attitudes (ethnic pride, separatistfeeling, stereotyping of ethnic groups), values, and social expectations. Each component was examined among 32S African American, Latino, Filipino, and Anglo adolescents at an integrated, ethnically balanced high school. The independence of the dimensions of ethnic identity were ind…

Depressive Symptomatology among HIV‐Positive Women in the Era of Haart
Objective: An enhanced stress and coping model was used to explain depression among HIV‐positive women in healthcare and community settings where highly active anti‐retroviral treatment (HAART) was commonplace. Method: HIV‐infected women in four cities ( N =978) were assessed, cross‐sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self‐reported level of depressive symptomatology was high.…
Health and Health Care Among Male-to-Female Transgender Persons Who Are HIV Positive
Recent studies have reported high rates of HIV infection among male-to-female transgender persons, but little research has examined how male-to-female transgender persons manage living with HIV. We compared demographic and health characteristics of 59 male-to-female transgender persons who were HIV positive with 300 nontransgender control subjects who were HIV positive. We found several demographic differences between the groups but no significan…
Religious groups as diffusers of HIV antibody testing and prevention messages
Using a quasi‐experimental design, this study examined how delivering a brief training to volunteers in church congregations impacted (a) church volunteers' persistence in delivering HIV antibody testing messages over time and (b) HIV antibody testing behavior of the church volunteers themselves. Church volunteers attended a briefing regarding delivery of public health messages to others and the churches were assigned to either: (a) a trained con…
