RESUMO

HIV represents a significant health burden in the United States. In 2012, the Centers for Disease Control and Prevention (CDC) stopped recommending many once-promoted interventions as part of a shift from one HIV intervention policy, Diffusion of Effective Behavioral Interventions (DEBI), to another, High Impact Prevention (HIP). Twenty-nine staff members from 10 organizations were interviewed to explore how organizations reacted to this shift. Three major themes emerged: (1) Personal experience, community assessment, and epidemiological evidence influenced organizations' perceptions of efficacy and preference for earlier interventions. (2) Organizations were concerned that HIP interventions were not a good fit for their priority populations. (3) Organizations were frustrated with the top-down approach by the CDC prioritizing HIP interventions over earlier interventions. These results indicate that organizations continue to see value in and provide DEBI interventions. In addition, a more participatory process incorporating qualitative evidence and organizations' experiences may be necessary to achieve widespread de-implementation of DEBI interventions.

RESUMO

PrEP adoption among African-American men-who-have-sex-with-men (AAMSM) remains low. We applied Diffusion-of-Innovations (DOI) theory to understand PrEP adoption processes among young HIV-negative/status unknown AAMSM (AAYMSM; N = 181; 17-24 years). Quantitative and qualitative analyses were used to examine predictors of PrEP diffusion stages. Most AAYMSM were in the persuasion stage (PrEP-aware, hadn't adopted; 72.4%). Our results suggest that model antecedents are DOI stage-specific. PrEP awareness (knowledge stage) was associated with lower levels of social stigma (p < .03) and greater health literacy (p < .05), while sexual risk (p < .03) and education (p < .03) predicted PrEP adoption (12.2%). PrEP efficacy and side effects were primary innovation characteristics influencing adoption receptivity in the persuasion stage. Interventions to improve PrEP diffusion should be tailored to stage-specific antecedents depending on how a community is stratified across the DOI stages.


RESUMEN: La adopción de Pre-exposición Profilaxis (PrEP) entre hombres afroamericanos que tienen relaciones sexuales con otros hombres (HASH) sige baja. Aplicamos la teoría de la difusión de innovaciones para comprender los procesos de adopción de la PrEP entre los hombres jóvenes afroamericanos que tienen relaciones sexuales con otros hombres (HJASH) VIH negativos/estado desconocido (HJASH; N = 181; 17­24 años). Se utilizaron análisis cuantitativos y cualitativos para examinar los predictores de las etapas de difusión de PrEP. La mayoría de los HJASH se encontraban en la etapa de persuasión (conscientes de la PrEP, no la habían adoptado; 72.4%). Nuestros resultados sugieren que los antecedentes del modelo son específicos de la etapas de la difusión de innovaciones. La conciencia de la PrEP (etapa de conocimiento) se asoció con niveles más bajos de estigma social (p <.03) y una mayor alfabetización en salud (p <.05), mientras que el riesgo sexual (p <.03) y la educación (p < .03) predijeron la adopción de la PrEP (12.2%). La eficacia y los efectos secundarios de la PrEP fueron las principales características de la innovación que influyeron en la receptividad de la adopción en la etapa de persuasión. Las intervenciones para mejorar la difusión de la PrEP deben adaptarse a los antecedentes específicos de la etapa, dependiendo de cómo se estratifique una comunidad en las etapas del la difusión de innovaciones.

RESUMO

HIV prevention and care peer education interventions have demonstrated effectiveness at changing HIV risk and care behaviors among a variety of at-risk populations in different settings. However, little is known about the implementation of this type of intervention in community-based settings. Further, there is limited information available regarding the facilitators and barriers to implementing peer education interventions in community-based settings. In this study, we explore implementation facilitators, barriers, and strategies to overcome these barriers among 12 organizations that implemented the SHIELD intervention, an evidenced-based peer education intervention for people who use drugs. Guided by the Consolidated Framework for Implementation Research, we identified several facilitators and barriers at the outer, inner individuals, and intervention level of the implementation process. Future evidence-based public health programs should, in addition to addressing effectiveness, be relevant to the needs and lives of clients.

RESUMO

BACKGROUND: Internet access is increasingly critical for adolescents with regard to obtaining health information and resources, participating in web-based health promotion, and communicating with health practitioners. However, past work demonstrates that access is not uniform among youth in the United States, with lower access found among groups with higher health-related needs. Population-level data yield important insights about access and internet use in the United States. OBJECTIVE: The aim of this study is to examine internet access and mode of access by social class and race and ethnicity among youth (aged 14-17 years) in the United States. METHODS: Using the Current Population Survey, we examined internet access, cell phone or smartphone access, and modes of connecting to the internet for adolescents in 2015 (unweighted N=6950; expanded weights N=17,103,547) and 2017 (unweighted N=6761; expanded weights N=17,379,728). RESULTS: Internet access increased from 2015 to 2017, but socioeconomic status (SES) and racial and ethnic disparities remained. In 2017, the greatest disparities were found for youth in low-income households (no home access=23%) and for Black youth (no home access=18%) and Hispanic youth (no home access=14%). Low-income Black and Hispanic youth were the most likely to lack home internet access (no home access, low SES Black youth=29%; low SES Hispanic youth=21%). The mode of access (eg, from home and smartphone) and smartphone-only analyses also revealed disparities. CONCLUSIONS: Without internet access, web-based dissemination of information, health promotion, and health care will not reach a significant segment of youth. Currently, SES and racial and ethnic disparities in access prolong health inequalities. Moreover, the economic impact of COVID-19 on Black, Hispanic, and low-income communities may lead to losses in internet access for youth that will further exacerbate disparities.

RESUMO

OBJECTIVES: Evaluate the relationships between social characteristics of Floridian persons living with HIV (PLWH) and both use of digital technologies and willingness to use eHealth for HIV-related information. METHODS: Ryan White case managers (N = 155) from 55 agencies in 47 Florida counties administered a survey to PLWH (N = 1268) from June 2016-April 2017. Multilevel logistic regression models were used to identify correlates of technology use and willingness. RESULTS: Use of mobile phones with text messaging was high (89%). Older (vs. younger) adults and non-Hispanic blacks (vs. whites) were less likely to use most technologies. These groups, along with Hispanics (vs. whites) were less likely to express willingness to use technologies for HIV-related information in models adjusting for use. CONCLUSIONS: Among PLWH in Florida, eHealth-related inequities exist. Willingness to engage in HIV-related eHealth is affected by social determinants, even when considering technology access. Although eHealth may reduce some healthcare inequities, it may exacerbate others.

RESUMO

Oral-Self Implemented HIV Testing (Oral-SIT) offers a low-cost way to extend the reach of HIV testing systems. It is unclear, however, if high risk populations are able to perform the test with high fidelity. Using a simulation-based research design, we administered desensitized Oral-SIT kits to African American MSM (AAMSM; 17-24 years, N = 178). Participants were HIV negative or never tested, and had never self-administered an Oral-SIT kit. We assessed performance fidelity, and hypothesized antecedents. High levels of social stigma were associated with lower levels of training knowledge (Range = No Errors: 51.9%, 4 Errors: 0.6%) and performance fidelity (Range = No Errors: 39.9%, 3 Errors: 1.7%). Training knowledge and prior testing history were positively associated with performance fidelity. The present work extends research on HIV-related social stigma and suggests that social stigma inhibits knowledge acquisition and task performance. The Oral-SIT training materials were understood by individuals with a wide-range of educational backgrounds. Interventions are needed, however, to further improve Oral-SIT performance fidelity.

RESUMO

Evidence-based interventions (EBIs) often require competent staff, or human resources (HR), for implementation. The empirical evidence characterizing the influence of HR fluctuations on EBI delivery is limited and conflicting. Using the Interactive Systems Framework, we explored staff fluctuation and the subsequent influence on RESPECT, an HIV prevention EBI. We conducted interviews with staff in two waves (n = 53, Wave I; n = 37, Wave II) in a national sample of organizations delivering RESPECT (N = 29). We analyzed interviews qualitatively to describe changes among RESPECT staff and explore the subsequent influences on RESPECT implementation. Organizations reported downsizing, turnover, and expansion of staff positions. Staff changes had multiple influences on RESPECT implementation including clients reached, fidelity to specific RESPECT protocols, and overall sustainability of RESPECT over time. HR fluctuations are common, and our analyses provide an initial characterization of the relationship between HR fluctuation and EBI implementation. Given the prominent influence of HR on EBI implementation, the Interactive Systems Framework is a useful guiding tool for future examinations.

RESUMO

We examined the potential for increasing the reach of HIV testing to African American youths through the dissemination of oral-HIV testing. From 2012 through 2013 we examined the perceptions of alternatives to pharmacy dissemination of SITs in African American youths (5 focus groups) and service providers (4 focus groups), and conducted an ethnographic study of pharmacies (n = 10). Participants perceived significant advantages to delivering SITs through community health and services for adolescents (e.g., increased confidentiality, reduced stigma) over pharmacy dissemination. Given proper attention to fit, SIT dissemination could be facilitated through distribution by health and social service sites, and by improving elements of pharmacy dissemination.

RESUMO

Relationship dynamics develop early in life and are influenced by social environments. STI/HIV prevention programs need to consider romantic relationship dynamics that contribute to sexual health. The aim of this study was to examine monogamous patterns, commitment, and trust in African American adolescent romantic relationships. The authors also focused on the differences in these dynamics between and within gender. The way that such dynamics interplay in romantic relationships has the potential to influence STI/HIV acquisition risk. In-depth interviews were conducted with 28 African American adolescents aged 14 to 21 living in San Francisco. Our results discuss data related to monogamous behaviors, expectations, and values; trust and respect in romantic relationships; commitment to romantic relationships; and outcomes of mismatched relationship expectations. Incorporating gender-specific romantic relationships dynamics can enhance the effectiveness of prevention programs.

RESUMO

Understanding the balance between fidelity and adaptation for evidence-based interventions has the potential to improve their translation from research to practice. The Translation into Practice study explores variation in program implementation within organizations utilizing the RESPECT program, an HIV counseling and testing intervention. Counselors (N = 70) were interviewed using a semistructured interview guide to examine both the influential factors on, and the subsequent adaptations to, RESPECT. Almost all counselors reported making adaptations (N = 69). Adaptations were made both to key characteristics (mean [M] = 2.24, standard deviation [SD] = 1.3) and to core components (M = 0.5, SD = 0.8). Counselors identified the environmental context and factors within the counseling context as common influences leading to adaptation. These findings suggest adaptations were a routine part of program usage. To improve implementation of the RESPECT program, further research is needed to assess the degree to which adaptations can be made to better meet the needs of agencies and clients without compromising fidelity.

RESUMO

PURPOSE: Collaboration among organizations offering sexual health and youth development services has the potential to provide youth with effective sexual health support. However, formally structured efforts (eg, coalition formation) may be impractical or unsuitable for low-income communities where resources are often already limited. Social network theories provide an alternative approach for building collaborative organizational networks. APPROACH: Research aims to evaluate the barriers and facilitators to collaboration in sexual health organizational networks. SETTING: Organizations in low income, urban, communities in Chicago and San Francisco that serve African American adolescents. PARTICIPANTS: Providers (n = 22) from organizations that offer sexual health services and youth development services. METHODS: Focus groups (n = 4) were conducted and analyzed utilizing a combination of coding strategies. RESULTS: Barriers to collaboration included resource limitations and competition, differences in organizational roles and deliverables, and prejudice and stigma. Identifying common ground among organizations was found to be a facilitator to collaboration. Social network concepts in conjunction with study findings lead to the development of a practice model that hypothesizes a pathway for organizations to improve collaboration without formally structured efforts. CONCLUSION: Our findings offer ways to encourage collaboration among organizations that support youth sexual health in low-income, urban, African American communities without relying on formal structures. Such collaborations may be critical for improving the provision of comprehensive sexual health support.

RESUMO

Using a probability-based neighborhood sample of urban African American youth and a sample of their close friends (N = 202), we conducted a one-year longitudinal study to examine key questions regarding sexual and drug using norms. The results provide validation of social norms governing sexual behavior, condom use, and substance use among friendship groups. These norms had strong to moderate homogeneity; and both normative strength and homogeneity were relatively stable over a one-year period independent of changes in group membership. The data further suggest that sex and substance using norms may operate as a normative set. Similar to studies of adults, we identified three distinct "norm-based" social strata in our sample. Together, our findings suggest that the norms investigated are valid targets for health promotion efforts, and such efforts may benefit from tailoring programs to the normative sets that make up the different social strata in a given adolescent community.

RESUMO

The current severe acute respiratory syndrome coronavirus 2 testing policy and practice limits testing as a prevention tool. Radical shifts are required to increase the scale of rapid testing strategies and improve dissemination and implementation of venue-based and self-testing approaches. Attention to the full translation pipeline is required to reach high-risk segments of the population.

RESUMO

High-quality implementation of evidence-based interventions is important for program effectiveness and is influenced by training and quality assurance (QA). However, gaps in the literature contribute to a lack of guidance on training and supervision in practice settings, particularly when significant adaptations in programs occur. We examine training and QA in relationship to program fidelity among organizations delivering a widely disseminated HIV counseling and testing EBI in which significant adaptations occurred due to new testing technology. Using a maximum variation case study approach, we examined training and QA in organizations delivering the program with high- and low-fidelity (agencies: 3 = high; 3 = low). We identified themes that distinguished high- and low-fidelity agencies. For example, high-fidelity agencies more often employed a team approach to training; demonstrated use of effective QA strategies; leveraged training and QA to identify and adjust for fit problems, including challenges related to adaptations; and understood the distinctions between RESPECT and other testing programs. The associations between QA and fidelity were strong and straightforward, whereas the relationship between training and fidelity was more complex. Public health needs high-quality training and QA approaches that can address program fit and program adaptations. The study findings reinforced the value of using effective QA strategies. Future work should address methods of increasing program fit through training and QA, identify a set of QA strategies that maximize program fidelity and is feasible to implement, and identify low-cost supplemental training options.

RESUMO

Tanzanian youth have high levels of HIV risk and poor access to HIV-testing. Oral self-implemented testing (Oral-SIT) provides an alternative that reduces barriers to HIV-testing. We examined adaptations to Oral-SIT training components in a randomized experiment to evaluate a "train-the-trainer" strategy for improving comprehension of graphic training materials. Participants (N = 257, age = 14-19 years) were randomly assigned to one of two self-training conditions: graphic instruction book (GIB) or Video-GIB. Outcomes included behavioral performance fidelity, self-reported comprehension, and intentions to seek treatment. Video-GIB participants, relative to GIB-only participants, had higher performance fidelity scores, made fewer performance errors, had better instruction comprehension, and were more likely to intend to seek treatment. Oral-SIT timing errors were significantly more common among GIB-only participants. Graphic training materials in conjunction with a "train-the-trainer" video has significant potential for increasing Oral-SIT's reach by overcoming technological and literacy barriers.

RESUMO

BACKGROUND: As more effective or efficient interventions emerge out of scientific advancement to address a particular public health issue, it may be appropriate to de-implement low-value interventions, or interventions that are less effective or efficient. Furthermore, factors that contribute to appropriate de-implementation are not well identified. We examined the extent to which low-value interventions were de-implemented among public health organizations providing HIV prevention services, as well as explored socio-economic, organizational, and intervention characteristics associated with de-implementation. METHODS: We conducted an online cross-sectional survey from the fall of 2017 to the spring of 2019 with organizations (N = 188) providing HIV prevention services in the USA. Organizations were recruited from the Center for Disease Control and Prevention's (CDC) website gettested.org from 20 metropolitan statistical areas with the highest HIV incidence. An organization was eligible to participate if the organization had provided at least one of the HIV prevention interventions identified as inefficient by the CDC in the last ten years, and one administrator familiar with HIV prevention programming at the organization was recruited to respond. Complete responses were analyzed to describe intervention de-implementation and identify organizational and intervention characteristics associated with de-implementation using logistic regression. RESULTS: Organizations reported 359 instances of implementing low-value interventions. Out of the low-value interventions implemented, approximately 57% were group, 34% were individual, and 5% were community interventions. Of interventions implemented, 46% had been de-implemented. Although we examined a number of intervention and organizational factors thought to be associated with de-implementation, the only factor statistically associated with de-implementation was organization size, with larger organizations-those with 50+ FTEs-being 3.1 times more likely to de-implement than smaller organizations (95% CI 1.3-7.5). CONCLUSIONS: While low-value interventions are frequently de-implemented among HIV prevention organizations, many persisted representing substantial inefficiency in HIV prevention service delivery. Further exploration is needed to understand why organizations may opt to continue low-value interventions and the factors that lead to de-implementation.

RESUMO

Objectives. Survey items used in surveillance systems to assess the use of emerging products like hookah and electronic inhalant devices (EIDs) may not match definitions used by high-risk populations. This qualitative study explored how African American youth and young adults (YYAs) (1) use hookah and EIDs and (2) identify patterns in the ways they describe and organize these products. Design. Individual in-person interviews were conducted among a sample of continuation high school and vocational school students in southern California. Participation was limited to those who had ever tried at least one tobacco product, self-identified as African American, and were between the ages of 14 and 26 years (n = 28). We conducted a content analysis to identify patterns in perceptions and use of these products. Results. African American YYAs recognized and described traditional hookah based on physical attributes, but for EIDs, including e-cigarettes, e-hookah, and vape pens, YYAs focused on reasons for using the product. Three primary categories emerged for reasons YYA used specific products: nicotine content and quitting, social facilitation, and use with marijuana. E-cigarettes were identified as quitting aids and as having nicotine but were not considered addictive. The term hookah recalled both the traditional and electronic pen-type products for YYAs. The terms vapes, hookah, wax pens, and others are used in the context of describing product use with marijuana. Conclusions. A better understanding of why African American YYAs use these products is needed to develop better measures for accurate rates of use, uncover differences in use between product types, and to develop effective prevention messaging.

RESUMO

A need exists for the promotion of diversity in the scientific workforce to better address health disparities. In response to this need, funding agencies and institutions have developed programs to encourage ethnic-minority and early-career scientists to pursue research careers. We describe one such program, the University of California, San Francisco, Visiting Professors Program, which trains scientists to conduct HIV/AIDS-related research in communities of color. The program provides training and mentoring in navigating grant processes and developing strong research proposals and provides crucial networking opportunities. Although this program is focused on community-based HIV prevention, its principles and methods are widely applicable.

RESUMO

OBJECTIVE: This study examined whether uncontrollable stressful life events were associated with sexual risk taking among adolescents across a 1-year period, and whether supportive friendships modified associations. DESIGN: Participants were 159 sexually active African American adolescents (57% male; mean age [SD] = 17.0 [1.5] years at baseline). Participants were recruited for in-person interviews through random digit dialing in one inner-city neighborhood characterized by high rates of poverty and crime relative to the surrounding city. MAIN OUTCOME MEASURES: Dependent variables included substance use before sexual activity and inconsistent condom use. RESULTS: Among adolescents who reported low levels of supportive friendships, uncontrollable stressors were associated with greater levels of sexual risk taking over time. In contrast, uncontrollable stressors were not associated with sexual risk taking among adolescents who reported high social support from friends; risk taking was typically moderate to high among these adolescents. CONCLUSION: Different processes may explain sexual risk taking among adolescents with varying levels of social support from friends. Adolescents with low support may be prone to engagement in health risk behavior as a stress response, while adolescents with high support may engage in risk behavior primarily due to peer socialization of risk.
