Integrating CBPR and Implementation Science to Develop a PrEP-Promotion Intervention for Black Transgender Women
Black/African American transgender (trans) women experience disproportionately high rates of HIV, yet few evidence-based interventions are designed specifically for them. This study outlines the development of the Sisters United intervention through the adaptation of ChiCAS , an evidence-based intervention for trans Latinas. Sisters United promotes use of pre-exposure prophylaxis (PrEP), condoms, and medically supervised gender-affirming hormone …
Comparative Analysis of Accessibility to Primary Activity Nodes in Port-Oriented Cities
This study assesses the accessibility and coverage of primary facilities in Cartagena and Buenaventura, two Colombian port cities that share comparable socioeconomic profiles but exhibit contrasting urban conditions. The aim is to examine how socioeconomic classification shapes equity in access to opportunities, emphasizing the role of territorial configuration in shaping everyday access to essential services. The methodological approach integrat…
From Watching to Calling
Substantial gaps exist in the theoretical conceptualization and practical development of entertainment-education, as studies often fail to account for the ways in which intrinsic message characteristics influence subsequent behavior. These gaps served as the impetus for an international collaborative project that evaluated Vencer el Miedo (“Overcome the Fear”), a Spanish-language program that aired in Mexico from January to March 2020. The teleno…
Overcoming Health Information Inequities
Although Valley fever represents a growing public health challenge for Central and Southern Californian residents, awareness remains severely limited. The California Department of Public Health (CDPH) ran a cross-platform campaign to mitigate this awareness gap and impact prevention behavior. This study evaluates exposure to the CDPH campaign, followed by an examination of the information consumption patterns associated with key health outcomes. …
Public Transportation Through the Clustering Analysis of Bus Stops. Case Study Manizales, Colombia

A Comparative Analysis, Through Geographical Accessibility, of Urban Public Transport Systems in Cities of Colombia's Coffee-Growing Region
Valuing urban public transport plays a vital role in the growth and development of a city. In addition, an exemplary system connection allows the formation of functional relationships between the different users and the surrounding environment. That is why, in this research, it is proposed as an objective to carry out a comparative analysis of the levels of coverage offered by Public Transport Systems in cities of the Colombian coffee region to v…
Spatial Coverage Analysis of Bus Stop Set and Its Relationship to the Surrounding Land Uses. Case Study, Manizales, Colombia
The main objective of the research is to determine the efficiency in population and area coverage of the set of bus stops to existing land uses in the city, allowing the identification of possible shortcomings, which leads to the formulation of restructuring proposals in terms of the location of the stops. The research methodology to be applied includes the use of geostatistical models of accessibility based on GIS-type digital tools, supported b…
Developing an mHealth program to improve HIV care continuum outcomes among young Black gay and bisexual men
This study demonstrates the potential of a video-based mHealth program to address the unique needs of YBGBM living with HIV, offering support and comprehensive information through a user-friendly interface and videos of peers living with HIV and of experts. The HCD approach allowed for continuous improvements to the concept to maximize cultural appropriateness, utility, and potential effectiveness for both YBGBM and HIV service organizations
Clinic Staff Perceptions of Implementing a Sexual and Reproductive Health Entertainment-Education Program for Young Women of Color
This is the first study to assess perceived implementation facilitators and barriers of an entertainment-education video intervention among SRH clinic staff. The intervention was well received, with certain barriers potentially alleviated by offering information about entertainment-education and multiple implementation methods. These findings can help improve dissemination efforts for video-based entertainment-education interventions in clinics s…
The Effect of an Entertainment-Education Intervention on Reproductive Health of Young Women of Color
While teen pregnancy rates in the United States have been declining for decades, they remain the highest of all western countries. Within the U.S., Black and Latina teens experience disproportionate rates of unplanned pregnancy. Plan A is an entertainment-education video intervention that was developed to help address these disparities, in part by emphasizing the ability of young cisgender women to control when they become pregnant by using an ef…
Development and evaluation of a social marketing campaign to address methamphetamine use in Los Angeles County
Social marketing campaigns hold promise for impacting methamphetamine prevention and cessation behaviors. This study adds to the limited literature on mass marketing interventions to address this major health issue
Overcome the Fear (Vencer el Miedo)
Background Adolescents in Mexico experience high pregnancy and birth rates. A collaboration with Grupo Televisa led to the development of an entertainment-education telenovela intervention, Overcome the Fear (OTF) , which aired in 2020 to a national audience and addressed adolescent sexual and reproductive health (SRH) topics. This study details the development and evaluation of OTF ’s impact on adolescent contraceptive practices and parent-adole…
Integrated Multicultural Media Campaign to Increase Covid-19 Education and Vaccination Among Californians, 2021
Despite the availability of safe, effective COVID-19 vaccines, many remain unvaccinated or partially vaccinated. In 2021, the California Department of Public Health launched a California-wide integrated multicultural vaccine media campaign. The campaign was evaluated in two waves through online surveys with adults (n = 1594; n = 1575). Campaign exposure was associated with looking for vaccine information, visiting a state vaccine Web site, and be…
Brief Report
We investigated pre-exposure prophylaxis (PrEP) uptake, adherence, and discontinuation among young app-using men who have sex with men in California (N = 761). Approximately, 9.7% of participants had ever used PrEP; 87% of those deemed good candidates for screening (indicated by a Centers for Disease Control and Prevention risk index score ≥10) were not current or past users. PrEP use was associated with higher income [adjusted odds ratio (aOR): …
Syphilis Experiences and Risk Perceptions Among Repeatedly Infected Men Who Have Sex with Men
Additional qualitative studies of men who have sex with men should be conducted to better understand the continuing syphilis epidemic and to help identify the most promising intervention strategies
Cyberbullying Perpetration and Victimization Among Middle-School Students
Objectives. We examined correlations between gender, race, sexual identity, and technology use, and patterns of cyberbullying experiences and behaviors among middle-school students. Methods. We collected a probability sample of 1285 students alongside the 2012 Youth Risk Behavior Survey in Los Angeles Unified School District middle schools. We used logistic regressions to assess the correlates of being a cyberbully perpetrator, victim, and perpet…
Acceptable Interventions to Reduce Syphilis Transmission Among High-Risk Men Who Have Sex With Men in Los Angeles
Objectives. We examined perceptions of and attitudes toward existing and potential syphilis interventions, including case management and Web-based programs, to increase syphilis testing among high-risk men who have sex with men (MSM). Methods. Between October 2010 and June 2011, we conducted in-depth interviews with 19 MSM in Los Angeles, California, with repeat early syphilis infections (primary, secondary, and early latent syphilis) within the …

There’s No Place Like Home
In response to high chlamydia and gonorrhea morbidity, particularly among young African American and Latina women, the Los Angeles County Department of Public Health launched a free home testing program for Chlamydia trachomatis and Neisseria gonorrhoeae. The primary objectives were to increase chlamydia and gonorrhea testing by removing key barriers and to motivate young women to screen routinely for these sexually transmitted diseases (STDs). T…
Sexually Explicit Cell Phone Messaging Associated With Sexual Risk Among Adolescents
OBJECTIVES: Sexting (sending/receiving sexually explicit texts and images via cell phone) may be associated with sexual health consequences among adolescents. However, to date, no published data from a probability-based sample has examined associations between sexting and sexual activity. METHODS: A probability sample of 1839 students was collected alongside the 2011 Youth Risk Behavior Survey in Los Angeles high schools. Logistic regressions wer…
Sexuality and Homelessness in Los Angeles Public Schools
Recently, Corliss et al.1 published important findings demonstrating the disproportionate numbers of sexual minority youths who experience homelessness in Massachusetts. Because of great variations in homelessness by region, we would like to add to this body of evidence with similar data from Los Angeles, California. We collected data on sexuality and homelessness experiences in conjunction with the 2011 administration of the Youth Risk Behavior …
Circuit parties
The syphilis epidemic among men who have sex with men (MSM) in major US cities and concomitant increases in high-risk sexual behavior, have raised concerns of increased HIV transmission in this population. Therefore, to provide information for health promotion and disease awareness efforts, we investigated sexual behaviors, partner selection preferences and HIV serostatus disclosure practices of MSM at the White Party in Palm Springs, California.…
An autoassociative model of causal reasoning and causal learning
The authors respond to F. Van Overwalle's (1998) critique of the explanatory coherence (ECHO) model of causal reasoning (P. Thagard, 1992) and its application to social reasoning (S. J. Read & A. Marcus-Newhall, 1993). Contrary to Van Overwalle's doubts about its possibility, a feedback model similar to ECHO that learns covariation information appropriately is presented. This model simulates Read and Marcus-Newhall's results and can also simulate…
