Substance use typologies among young people experiencing homelessness in seven cities across the United States: A latent class analysis

BACKGROUND

Substance use and other health-risk risk factors, including mental health, trauma, and sexual-risk behaviors, often co-occur among youth experiencing homelessness (YEH). The present study aimed to identify subgroups of YEH based on polysubstance use and the linkages to sociodemographic and health-risk characteristics.

METHODS

From June 2016 to July 2017, 1,426 YEH (aged 18-26 years) were recruited from seven cities (Houston, Los Angeles, Denver, Phoenix, New York City, St. Louis, San Jose). Participants provided information via a self-administered electronic survey on substance use, mental health, trauma, sexual risk behaviors, and sociodemographic characteristics. The majority of YEH identified as Black (37.3%), cisgender (92.8%), and heterosexual (69.2%). On average, YEH were 20.9 years (SD = 2.1). This study employed latent class analysis (LCA) to identify subgroups of YEH according to their substance use. Multinomial logistic regression analyses were conducted to identify sociodemographic and health-risk characteristics associated with class-membership.

RESULTS

Four latent classes of YEH substance use were identified: (1) high polysubstance use; (2) moderate stimulant and high marijuana, alcohol, and prescription drug use; (3) high marijuana, alcohol, and prescription drug use; (4) low/moderate marijuana and alcohol use. Multinomial logistic regression models indicated that geographic location, gender, race/ethnicity, mental health, trauma history, and sexual risk behaviors were significant correlates of substance use class membership among YEH.

CONCLUSIONS

These findings offer important implications for the prevention and treatment of substance use among YEH. Screening protocols should consider co-occurring risk factors such as traumatic experiences, sexual risk behaviors, and mental health history as indicators of polysubstance use.

Relationship between religiosity and HPV vaccine initiation and intention in urban black and hispanic parents

OBJECTIVE

Religion is believed to be an important sociocultural influence in the U.S., but little is known about how religiosity shapes the human papillomavirus (HPV) vaccine decision in racial/ethnic minorities. The purpose of this study was to examine the relationship between religiosity and HPV vaccine initiation and intention among urban, racial/ethnic minority parents of adolescents 11-14 years old.

DESIGN

This study employed a descriptive, cross-sectional design using baseline data from Black and Hispanic parents (N = 175 and 285, respectively) recruited from medically underserved communities. Chi-square tests for independence and independent-samples t-tests were run to assess sociodemographic differences in vaccine initiation and vaccine intention. Binary logistic regression analyses were conducted to determine whether religious attendance and religious salience were associated with parents' HPV vaccine decisions for their children.

RESULTS

Approximately 47% of Black parents had vaccinated their youth against HPV. Of those who had not initiated the vaccine for their child, 54% did not intend to do so. 54% of Hispanic parents had initiated the HPV vaccine for their youth. Of those who had not initiated the vaccine for their child, 51% did not intend to do so. Frequency of attendance at religious services and the importance of religion in one's life was not significantly correlated with HPV vaccine decision-making for Black nor Hispanic parents.

CONCLUSION

This study suggests that religiosity does not influence the HPV vaccine decision for urban, Black and Hispanic parents. Future studies using measures that capture the complexity of religion as a social construct are needed to confirm the findings. In addition, studies with representative sampling will enable us to make generalizations about the influence of religion on HPV vaccine decision-making for urban, racial/ethnic minority parents.

The Social, Mental, and Physical Health Impacts of the COVID-19 Pandemic on People With HIV: Protocol of an Observational International Multisite Study

ABSTRACT

As the COVID-19 pandemic spread across the world, immunocompromised individuals such as people with HIV (PWH) may have faced a disproportionate impact on their health and HIV outcomes, both from COVID-19 and from the strategies enacted to contain it. Based on the SPIRIT guidelines, we describe the protocol for an international multisite observational study being conducted by The International Nursing Network for HIV Research, with the Coordinating Center based at the University of California, San Francisco (UCSF) School of Nursing. Site Principal Investigators implement a standardized protocol to recruit PWH to complete the study online or in-person. Questions address demographics; HIV continuum of care indicators; mental and social health; COVID-19 and vaccination knowledge, attitudes, behaviors, and fears; and overall outcomes. Results of this study will contribute to knowledge that can inform responses to future public health crises to minimize their impacts on vulnerable populations such as PWH.

Advancing health equity through nursing research

BACKGROUND

Health inequities are major predictors of poor health and remain a complex and persistent challenge globally and in the United States. Research has documented the underlying causes and mechanisms that give rise to health disparities. However, it lacks adequate attention to the strategies needed to build upon promulgated research to address equity-based challenges to improve health.

PURPOSE

This paper describes how building and supporting diverse research teams can play a central role in increasing the research capacity and participation of diverse populations to improve the health of individuals, families, and communities.

METHODS

Exemplars from work and discussion of strategies to grow nursing's health equity workforce are presented.

DISCUSSION

Actions to build and leverage partnerships to expand capacity, maximize the impact of health equity outcomes, and cultivate a supportive environment to grow the health equity scientific workforce are discussed.

CONCLUSION

Nurse scientists can address health equity through the research process.

Adapting an evidence-based mindfulness-based intervention for sheltered youth experiencing homelessness

OBJECTIVES

Youth experiencing homelessness (YEH) face challenges that impact their physical, mental, and social wellbeing, emotion regulation, and coping. Mindfulness reduces stress and improves resilience, emotion regulation, and executive functioning. Mindfulness-based interventions (MBI) teach the practice of mindfulness to foster present-moment attention without judgement and enhance self-observation and self-regulation, resulting in greater awareness of thoughts and emotions and improved interpersonal relationships. One such intervention, .b, has been shown to lower stress among youth. While a pilot study of .b among sheltered youth found the intervention to be feasible, the need for modifications was identified to improve its relevance, accessibility, and incorporate a trauma-informed approach.

METHODS

We used the ADAPT-ITT (Assessment, Decisions, Administration, Production, Topical experts, Integration, Training staff, and Testing) framework to adapt the .b mindfulness intervention to YEH living in an emergency shelter. Nine focus group discussions (n = 56), key informant interviews (n = 8), and beta testing with five youth working group sessions (n = 10) identified needed modifications.

RESULTS

Adaptations to the curriculum and delivery modality were made to approximate the average length of stay in the shelter; integrate trauma-informed care approaches; increase diversity of images by race, ethnicity, age, sexual orientation, and gender identity; and increase the relevance of the audio-visual components.

CONCLUSIONS

Youth and the health and social services providers who care for youth generally liked the core concepts and presentation of the curriculum. Using the ADAPT-ITT framework, minor, yet important, changes were made to increase the relevance, acceptability, and feasibility of the intervention. Next steps are to conduct a randomized attention control pilot study to assess feasibility and acceptability.

Impact of preparing nursing students to deliver a parent-based sexual health intervention on attitudes and intentions for sexual health education and parent communication counseling: a mixed methods study

BACKGROUND

Nurses are well positioned to promote sexual health but are not adequately prepared in their nursing programs to engage families on this topic and often lack the knowledge and confidence necessary to counsel families about sexual health communication. The purpose of this study was to determine how facilitating a parent-based sexual health intervention would impact nursing students' attitudes and intentions about sexual health education and parent communication counseling.

METHODS

Using an embedded mixed-methods design, which integrated a quasi-experimental framework, we examined the impact of participation in a parent-based sexual health intervention among 126 baccalaureate nursing students enrolled in a community/public health nursing clinical course. Independent t-tests, chi-squared tests, and the Mann-Whitney U test were used to compare intervention and control groups at baseline. Multiple linear regression was used to compare the groups for pre-post changes. Qualitative content analysis was used to analyze exit interview transcripts.

RESULTS

We found statistically significant differences in nursing students' confidence to teach sexual health (p = < 0.001), satisfaction with skills as a sexual health educator (p = < 0.001), beliefs about the efficacy of parent-adolescent communication for reducing negative sexual outcomes among adolescents (p = < 0.001), and intentions to counsel parents on sexual health (p = < 0.001), with greater improvements in the intervention group than in the control group. Furthermore, we found statistically significant differences in nursing students' intentions to counsel parents about the HPV vaccine (p = < 0.01) and to endorse the HPV vaccine (p = < 0.05), with greater improvements in the intervention group than in the control group. Across all survey categories, qualitative findings confirmed improvements seen on the pre-post survey.

CONCLUSION

Providing evidence-based adolescent sexual health training, including sexual health education content and discussion strategies, can prepare nursing students to strongly endorse sexual health communication and HPV vaccination uptake and to counsel parents on initiating and navigating these conversations with their youth. Our project exemplifies how a nursing program could organize an immersive experience, or elective within a specialty area, that aligns with the competency-based approach endorsed by the American Association of Colleges of Nursing.

TRIAL REGISTRATION

This study was registered with ClinicalTrials.gov (NCT02600884) on 09/01/2015; the first participant was recruited on 09/29/2015.

Lessons Learned from All for Them: Best Practices for a Cross-Collaboration Approach to HPV Vaccination in Public Schools

The Community Preventive Services Task Force endorses vaccination programs in schools to increase access to vaccinations. However, implementing a school-based approach requires substantial coordination, planning, and resources. All for Them (AFT) is a multilevel, multicomponent approach to increase HPV vaccination among adolescents attending public schools in medically underserved areas in Texas. AFT comprised a social marketing campaign, school-based vaccination clinics, and school nurse continuing education. Process evaluation metrics and key informant interviews to understand experiences with AFT program implementation informed lessons learned. Lessons emerged in six domains: strong champion, school-level support, tailored and cost-effective marketing approaches, mobile provider collaboration, community presence, and crisis management. Strong support at district and school levels is vital for gaining principal and school nurse buy-in. Social marketing strategies are integral to program implementation and should be adjusted to maximize their effectiveness in motivating parents to vaccinate children against HPV, which also can be achieved through increased community presence of the project team. Preparing contingency plans and flexibility within the program can facilitate appropriate responses to provider restrictions in mobile clinics or in the event of unforeseen crises. These important lessons can offer useful guidelines for the development of prospective school-based vaccination programs.

Examining sources of Social Support and Depression Prevention Among Pregnant Youth Experiencing Homelessness: Outcomes of a Seven-City Study

Young adults experiencing homelessness (YAEH) with pregnancy history are at higher depression risk. Receiving social support is protective for depression in pregnancy. This study differentiates social support sources associated with depression by pregnancy history among YAEH.Using a subsample of data collected from YAEH in seven US cities that were collected through REALYST, we conducted stratified logistic regression models (by pregnancy history) to identify support sources associated with depression. Logistic regression analysis including the interaction term (i.e., pregnancy history x support sources) using the full sample was then conducted.A higher proportion with pregnancy history reported depression compared to those without. Support from home-based peers was significantly associated with reduced depression risks among YAEH with pregnancy history, but not among youth without. Home-based supports were less frequently indicated by homeless female youth with pregnancy experience.Home-based social support is protective against major depression for YAEH with pregnancy experience. Findings of this study suggest that interventions addressing depression among YAEH should take their pregnancy history and social support sources into consideration. Specifically, for YAEH with pregnancy history, facilitating supportive social ties with home-based peers may be promising in reducing their depression risks.

Few Do and To Few: Disclosure of Suicidal Thoughts in Friendship Networks of Young Adults Experiencing Homelessness

Disclosure of one's suicidal thoughts is a pivotal but under-investigated mechanism for preventing suicide among young adults experiencing homelessness (YAEH). In a sample of 527 YAEH, we adopted a multi-level perspective to assess patterns and correlates of disclosure in their friendship networks. Less than one-third of YAEH disclosed their suicidal thoughts-half of them doing so during a suicidal crisis-and only disclosed to 21% of their friends. Multilevel modeling showed that YAEH who reported a history of unmet mental health needs were more likely to have disclosed to a friend, and friends who were sources of social support were most highly sought out for disclosures. Our findings highlight the need for cultivating safe environments that promote disclosures among YAEH.

Prevalence and Correlates of Illicit Substance Use Among Young Adults Experiencing Homelessness in Seven Cities Across the United States

Background

Young adults experiencing homelessness (YAEH) engage in substantially higher substance use rates than housed young adults. This current study builds on previous research by investigating the prevalence of and salient correlates of illicit substance use across a seven-city sample.

Methods

This study used the Homeless Youth Risk and Resiliency Survey (HYRRS) dataset, n=1426 Young adults experiencing homelessness to study patterns and correlates of illicit substance use.

Results

Multivariate logistic regression analyses were used to assess correlates of substance use. Study site, age, gender identity, sexual orientation, history of suicidal ideation, use of specific substances, and trading sex for drugs were associated with five types of illicit substance use (ecstasy, cocaine, crack, methamphetamine, and injection drug use).

Conclusion

Findings indicate that substance use interventions for YAEH must be multifaceted, addressing illicit and multiple substance use, along with the myriad factors associated with substance use among this at-risk group.

Experiences of discrimination among young adults experiencing homelessness: Relationship to mental health outcomes

Young adults experiencing homelessness (YAEH) are at high risk for discrimination. Limited research has documented the extent of discrimination experiences and their relationship to mental health outcomes among this group. This study used data from YAEH who completed self-administered surveys across seven U.S. cities (N = 1,426) to examine the rates and correlates of discrimination experiences and their association with psychological distress and suicidal ideation. Chi-square and multivariate logistic regressions were used to examine the relations between perceived discrimination and race, gender identity, sexual orientation, foster care history, criminal justice history, reasons for homelessness, and length of time homeless. Then, logistic regression was used to examine whether discrimination increased the odds of psychological distress and suicidal ideation, controlling for other factors. Three-fourths (75.8%) of the sample (n = 1,055) reported experiencing at least one of the five forms of everyday discrimination experiences at least a few times a year, with the most common reason attributed to their housing situation (46%). Sexual orientation, juvenile justice involvement, and having been homeless for 2 years or more were associated with increased odds of experiencing discrimination. Discrimination was a strong predictor of psychological distress but was significant only at the bivariate level for suicidal ideation. Study results suggest that experiences of discrimination are common among YAEH and that these experiences increase risk for psychological distress. Providers working with YAEH need to validate and acknowledge the impact of these experiences on mental health. And, communities need to work to reduce discrimination experiences by targeting stigma against YAEH. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Understanding the Correlates of Firearm Violence Involvement Among Young Adults Experiencing Homelessness: A 7-City Study

INTRODUCTION

Young adults experiencing homelessness are vulnerable to firearm violence. This study aims to explore the correlates of firearm violence involvement among this vulnerable population, which may inform firearm violence reduction intervention development.

METHODS

Between 2016 and 2017, young adults experiencing homelessness aged 18-26 years (N=1,426) were recruited in 7 U.S. cities. Respondents completed a self-administered computer-assisted anonymous survey regarding their homeless experiences and violence involvement. Separate multivariate logistic regression models were conducted in 2020 to explore the correlates of direct firearm violence victimization, witness of firearm violence, and firearm violence perpetration.

RESULTS

A high proportion of young adults experiencing homelessness were involved in firearm violence (witnessing firearm violence: 40%; direct firearm violence victimization: 28%; perpetration: 18%). Stressful experiences, such as childhood trauma and street victimization, were associated with greater odds of firearm violence involvement. Black (OR=2.4, p<0.001) and Latinx (OR=2.0, p<0.05) young adults had greater odds of experiencing direct firearm violence victimization than White young adults. Black (OR=2.0, p<0.01) and Latinx (OR=2.4, p<0.001) young adults were also at greater risk of witnessing firearm violence. Young adults with mental illness had greater odds of being directly victimized by firearm violence (OR=1.7, p<0.01).

CONCLUSIONS

Given the inter-related nature of firearm violence involvement and given that risk factors for violence are often embedded in social and structural contexts, multipronged community-based approaches to prevent firearm violence among young adults experiencing homelessness are necessary. Targeted efforts may be indicated to attenuate the risk and promote resilience among subgroups of young adults experiencing homelessness who are disproportionately affected by firearm violence.

Efficacy of a Just-in-Time Adaptive Intervention to Promote HIV Risk Reduction Behaviors Among Young Adults Experiencing Homelessness: Pilot Randomized Controlled Trial

BACKGROUND

People experiencing homelessness have higher rates of HIV than those who are stably housed. Mental health needs, substance use problems, and issues unique to homelessness such as lack of shelter and transiency need to be considered with regard to HIV prevention. To date, HIV prevention interventions for young adults experiencing homelessness have not specifically addressed modifiable real-time factors such as stress, sexual or drug use urge, or substance use, or been delivered at the time of heightened risk. Real-time, personalized HIV prevention messages may reduce HIV risk behaviors.

OBJECTIVE

This pilot study tested the initial efficacy of an innovative, smartphone-based, just-in-time adaptive intervention that assessed predictors of HIV risk behaviors in real time and automatically provided behavioral feedback and goal attainment information.

METHODS

A randomized attention control design was used among young adults experiencing homelessness, aged 18-25 years, recruited from shelters and drop-in centers in May 2019. Participants were randomized to either a control or an intervention group. The intervention (called MY-RID [Motivating Youth to Reduce Infection and Disconnection]) consisted of brief messages delivered via smartphone over 6 weeks in response to preidentified predictors that were assessed using ecological momentary assessments. Bayesian hierarchical regression models were used to assess intervention effects on sexual activity, drug use, alcohol use, and their corresponding urges.

RESULTS

Participants (N=97) were predominantly youth (mean age 21.2, SD 2.1 years) who identified as heterosexual (n=51, 52%), male (n=56, 57%), and African American (n=56, 57%). Reports of sexual activity, drug use, alcohol use, stress, and all urges (ie, sexual, drug, alcohol) reduced over time in both groups. Daily drug use reduced by a factor of 13.8 times over 6 weeks in the intervention group relative to the control group (Multimedia Appendix 4). Lower urges for sex were found in the intervention group relative to the control group over the duration of the study. Finally, there was a statistically significant reduction in reports of feeling stressed the day before between the intervention and control conditions (P=.03).

CONCLUSIONS

Findings indicate promising intervention effects on drug use, stress, and urges for sex in a hard-to-reach, high-risk population. The MY-RID intervention should be further tested in a larger randomized controlled trial to further investigate its efficacy and impact on sexual risk behaviors.

A Nurse Case Management HIV Prevention Intervention (Come As You Are) for Youth Experiencing Homelessness: Protocol for a Randomized Wait-list Controlled Trial

Background

Youth experiencing homelessness are more likely than housed youth to experience premature death, suicide, drug overdose, pregnancy, substance use, and mental illness. Yet while youth experiencing homelessness are 6 to 12 times more likely to become infected with HIV than housed youth, with HIV prevalence as high as 16%, many do not access the prevention services they need. Despite adversities, youth experiencing homelessness are interested in health promotion programs, can be recruited and retained in interventions and research studies, and demonstrate improved outcomes when programs are tailored and relevant to them.

Objective

The study aims to compare the efficacy of a nurse case management HIV prevention and care intervention, titled Come As You Are, with that of usual care among youth experiencing homelessness aged 16 to 25 years.

Methods

The study is designed as a 2-armed randomized wait-list controlled trial. Participants (n=450) will be recruited and followed up for 9 months after the intervention for a total study period of 12 months. Come As You Are combines nurse case management with a smartphone-based daily ecological momentary assessment to develop participant-driven HIV prevention behavioral goals that can be monitored in real-time. Youth in the city of Houston, Texas will be recruited from drop-in centers, shelters, street outreach programs, youth-serving organizations, and clinics.

Results

Institutional review board approval (Committee for the Protection of Human Subjects, University of Texas Health Science Center at Houston) was obtained in November 2018. The first participant was enrolled in November 2019. Data collection is ongoing. To date, 123 participants have consented to participate in the study, 89 have been enrolled, and 15 have completed their final follow-up.

Conclusions

There is a paucity of HIV prevention research regarding youth experiencing homelessness. Novel and scalable interventions that address the full continuum of behavioral and biomedical HIV prevention are needed. This study will determine whether a personalized and mobile HIV prevention approach can reduce HIV risk among a hard-to-reach, transient population of youth at high risk.

Perceived Impacts, Acceptability, and Recommendations for Ecological Momentary Assessment Among Youth Experiencing Homelessness: Qualitative Study

BACKGROUND

The use of ecological momentary assessment (EMA) to study youth experiencing homelessness (YEH) behaviors is an emerging area of research. Despite high rates of participation and potential clinical utility, few studies have investigated the acceptability and recommendations for EMA from the YEH perspective.

OBJECTIVE

This study aimed to describe the perceived benefits, usability, acceptability, and barriers to the use of EMA from the homeless youth perspective.

METHODS

YEH were recruited from a larger EMA study. Semistructured exit interviews were performed using an interview guide that focused on the YEH experience with the EMA app, and included perceived barriers and recommendations for future studies. Data analyses used an inductive approach with thematic analysis to identify major themes and subthemes.

RESULTS

A total of 18 YEH aged 19-24 years participated in individual and group exit interviews. The EMA was highly acceptable to YEH and they found the app and EMA surveys easy to navigate. Perceived benefits included increased behavioral and emotional awareness with some YEH reporting a decrease in their high-risk behaviors as a result of participation. Another significant perceived benefit was the ability to use the phones for social support and make connections to family, friends, and potential employers. Barriers were primarily survey and technology related. Survey-related barriers included the redundancy of questions, the lack of customizable responses, and the timing of survey prompts. Technology-related barriers included the "freezing" of the app, battery charge, and connectivity issues. Recommendations for future studies included the need to provide real-time mental health support for symptomatic youth, to create individually customized questions, and to test the use of personalized motivational messages that respond to the EMA data in real time.

CONCLUSIONS

YEH are highly receptive to the use of EMA in studies. Further studies are warranted to understand the impact of EMA on YEH behaviors. Incorporating the YEH perspective into the design and implementation of EMA studies may help minimize barriers, increase acceptability, and improve participation rates in this hard-to-reach, disconnected population.

The intersection of housing and mental well-being: Examining the needs of formerly homeless young adults transitioning to stable housing

We examine the challenges formerly homeless young adults (FHYAs) face after they transition out of homelessness. Considering the adversities FHYAs face, it is unclear how transitioning to stable housing may affect their mental well-being or what types of stressors they may experience once housed. This study investigates the social environment young adults encounter in their transition to stable housing and examines trauma and social coping predictors of mental health symptoms in a sample of FHYAs to generate new knowledge for better intervening to meet their needs. Data were obtained from REALYST, a national research collaborative comprised of interdisciplinary researchers investigating young adults' (ages 18-26) experiences with homelessness. Cross-sectional data for 1426 young adults experiencing homelessness were collected from 2016 to 2017 across seven cities in the United States (i.e., Los Angeles, Phoenix, Denver, Houston, San Jose, St. Louis, and New York City). The analytical sub-sample for this study consisted of 173 FHYAs who were housed in their own apartment (via voucher from Housing and Urban Development or another source) or in transitional living programs during their participation in the study. Ordinary Least Squares regression was used to examine the influence of trauma and social coping strategies on indicators of mental well-being. Findings indicated that higher adversity scores and higher mental health help-seeking intentions were positively associated with higher levels of stress, psychological distress, and depression severity. Higher level of social coping was associated with lower levels of depression severity. Logistic regression results showed that young adults with higher adversity scores had higher odds of reporting clinical levels of post-traumatic symptoms. The study implications suggest that FHYAs who transition to stable housing continue to need support navigating and coping with stressful life events; and interventions that help FHYAs develop strong networks of social supports are needed to promote positive mental well-being.

A Web-Based Game for Young Adolescents to Improve Parental Communication and Prevent Unintended Pregnancy and Sexually Transmitted Infections (The Secret of Seven Stones): Development and Feasibility Study

Background

Early adolescent unintended pregnancy and sexually transmitted infection prevention are significant public health challenges in the United States. Parental influence can help adolescents make responsible and informed sexual health decisions toward delayed sexual debut; yet parents often feel ill equipped to communicate about sex-related topics. Intergenerational games offer a potential strategy to provide life skills training to young adolescents (aged 11-14 years) while engaging them and their parents in communication about sexual health.

Objective

This study aims to describe the development of a web-based online sexual health intergenerational adventure game, the Secret of Seven Stones (SSS), using an intervention mapping (IM) approach for developing theory- and evidence-based interventions.

Methods

We followed the IM development steps to describe a theoretical and empirical model for young adolescent sexual health behavior, define target behaviors and change objectives, identify theory-based methods and practical applications to inform design and function, develop and test a prototype of 2 game levels to assess feasibility before developing the complete 18-level game, draft an implementation plan that includes a commercial dissemination strategy, and draft an evaluation plan including a study design for a randomized controlled trial efficacy trial of SSS.

Results

SSS comprised an adventure game for young adolescent skills training delivered via a desktop computer, a text-based notification system to provide progress updates for parents and cues to initiate dialogue with their 11- to 14-year-old child, and a website for parent skills training and progress monitoring. Formative prototype testing demonstrated feasibility for in-home use and positive usability ratings.

Conclusions

The SSS intergenerational game provides a unique addition to the limited cadre of home-based programs that facilitate parent involvement in influencing young adolescent behaviors and reducing adolescent sexual risk taking. The IM framework provided a logical and thorough approach to development and testing, attentive to the need for theoretical and empirical foundations in serious games for health.

Firearm Access and Suicidal Crises Among Young Adults Experiencing Homelessness in the United States

Background: Young adults experiencing homelessness (YAEH) report high rates of suicidal crises. Having access to firearms during suicidal crises elevates risk of death by suicide. Yet, no known information exists about firearm access among YAEH. Aims: We aimed to examine the proportion of participants who had firearm access, as well as the association between past-year suicidal crises and firearm access among participants. Method: We recruited 1,426 YAEH (18-26 years old) from homelessness service settings in seven US cities. Logistic regression analyses were used to examine the association between past-year suicidal crises and firearm access. Results: One third of the sample reported having easy firearm access. YAEH who experienced suicidal ideation and suicide attempts were more likely to report firearm access. Limitations: Results from this cross-sectional study cannot be causally interpreted nor generalized to all YAEH. Conclusion: A substantial segment of YAEH had easy firearm access and it was more common for YAEH with suicidal crises to have firearm access. Reducing firearm access should be part of suicide prevention planning for YAEH in the US but requires comprehensive and innovative solutions.

Firearm Violence Exposure and Suicidal Ideation Among Young Adults Experiencing Homelessness

PURPOSE

This study aimed to explore the association between direct exposure, indirect exposure, and perpetration of gun violence and suicidal ideation among young adults experiencing homelessness (YAEH).

METHODS

YAEH (n = 1,426) in seven cities across the U.S. were surveyed. Logistic regression analyses were conducted to examine the association between lifetime gun violence exposure and suicidal ideation in the past 12 months.

RESULTS

Forty-five percent (n = 641) of YAEH had experienced direct or indirect gun violence, whereas 17% (n = 247) had engaged in gun violence perpetration. Gun violence perpetration is associated with elevated suicidal ideation risk (odds ratio = 1.46; 95% confidence interval = 1.02-2.01) among YAEH.

CONCLUSIONS

A high percentage of YAEH were exposed to firearm violence. Cross-sector, multiagency collaborations are warranted to reduce firearm violence exposure among this vulnerable population. Homeless service providers should screen for gun violence exposure and suicide risk and target prevention efforts on YAEH with a history of gun violence perpetration.

Urban Stress Indirectly Influences Psychological Symptoms through Its Association with Distress Tolerance and Perceived Social Support among Adults Experiencing Homelessness

Traditionally, intrapersonal characteristics (distress tolerance) and interpersonal characteristics (social support) have been studied separately rather than simultaneously. In the current study, we address this gap by simultaneously examining these characteristics as potential indirect associations linking established urban stress-depression and urban stress-Post-Traumatic Stress Disorder (PTSD) relationships. Adults experiencing homelessness were recruited from six homeless shelters in Oklahoma City (n = 567). Participants self-reported urban life stress (Urban Life Stress Scale), distress tolerance (Distress Tolerance Scale), social support (Interpersonal Support Evaluation List 12), major depressive disorder (Patient Health Questionnaire-8), and PTSD symptoms (Primary Care Post-Traumatic Stress Disorder screener). Covariate-adjusted structural equation models indicated a significant indirect effect of distress tolerance on the urban stress-depression (b = 0.101, 95% CI = 0.061, 0.147) and urban stress-PTSD (b = 0.065, 95% CI = 0.023, 0.112) relationships. Additionally, a significant indirect effect of social support on the urban stress-depression (b = 0.091, 95% CI = 0.053, 0.133) and urban stress-PTSD relationships (b = 0.043, 95% CI = 0.006, 0.082) was evident. Further, both the urban stress-depression (b = 0.022, 95% CI = 0.011, 0.037) and urban stress-PTSD relationships (b = 0.014, 95% CI = 0.005, 0.026) were associated indirectly through social support to distress tolerance. Interventions that aim to increase social support may also increase distress tolerance skills and indirectly reduce depressive and PTSD symptoms in the context of urban stress among adults experiencing homelessness.

Bridging the Digital Divide Among Racial and Ethnic Minority Men Who Have Sex With Men to Reduce Substance Use and HIV Risk: Mixed Methods Feasibility Study

BACKGROUND

Ecological momentary assessment (EMA) is a promising data collection tool for mobile health interventions targeting episodic health behaviors. For substance-using men who have sex with men (SUMSM), EMA is becoming more widely utilized in efforts to characterize substance use and sexual risk factors for HIV transmission. However, recent literature demonstrates emerging concerns over compliance and lower EMA engagement and data concordance among racial and ethnic minority SUMSM.

OBJECTIVE

This study aimed to provide a qualitative evaluation of the barriers and facilitators of EMA as a data collection tool among racial and ethnic minority SUMSM.

METHODS

Between October and November 2017, 45 racial and ethnic minority SUMSM were recruited from a list of prior research participants at the San Francisco Department of Public Health to participate in daily EMA surveys on their substance use and sexual health behaviors for 1 week, followed by in-person focus groups (FGs). A total of 4 FGs explored the participants' experiences with the surveys, issues regarding privacy and confidentiality, and suggestions for improvement. Qualitative analysis was performed using content analysis. Descriptive statistics and Fisher exact tests were used to assess the associations between demographics or substance use behaviors and EMA completion.

RESULTS

Overall, 93.9% (295/314) of all delivered surveys were initiated, and of those, 98.0% (289/295) were completed. Neither participant demographics, including race (P=.65) or age (P=.43), nor substance use behaviors, including the frequency of alcohol (P=.40) or methamphetamine (P=.91) use or any cocaine (P=.28), crack (P=.99), or polysubstance use (P=.24), were found to be associated with survey completion. Overall, participants were receptive to the text message-based EMA surveys. Facilitators included survey timing, user-friendly survey design, survey-stimulated self-reflection, coding of sensitive phrases, and other privacy benefits of a mobile survey. Barriers included an inability to correct texting errors and participants' perception of judgment or stigmatization related to questions about condomless sex. To improve EMA compliance and uptake, participants suggested adding response confirmations, clarifying survey language, and continuing to diversify the study audience.

CONCLUSIONS

EMA appears to be feasible and acceptable among this sample of racial and ethnic minority SUMSM. Close attention to EMA study design and the development of nonjudgmental, contextualized questions regarding stigmatized health behaviors may be critical to further improve EMA compliance.

Sexual risk classes among youth experiencing homelessness: Relation to childhood adversities, current mental symptoms, substance use, and HIV testing

The aim of this study was to determine whether there are meaningful subgroups with different types of sexual risk behaviors among youth experiencing homelessness and examine the associations between potential classes and other risk variables. A latent class analysis was used to identify classes of youth according to sexual risk behaviors and sexual assault. A two-class solution was found to be the best fit for the data-Lower and Higher Risk groups. The Higher Risk class had significantly higher levels of synthetic marijuana and alcohol use, mental health diagnoses, and were more likely to have been tested for HIV than the Lower Risk group. Youth were more likely to be in the Higher Risk group if they were cisgender female or lesbian, gay, bisexual, or questioning (LGBQ). Nearly all youth (10/11) who reported having HIV infection were in the Higher Risk group. The Lower Risk group were sexually active but had lower rates of risk behaviors and sexual assault. Youth who were not sexually active had the lowest rates of marijuana and alcohol use as well as HIV testing. Health and social service providers should be aware of the added risks for stress, mental distress, mental health diagnoses, and substance use among youth who also report higher risk sexual behaviors and treat as needed.

Prevalence and correlates of nonmedical use of prescription drugs (NMUPD) among Young adults experiencing homelessness in seven cities across the United States

BACKGROUND

Nonmedical use of prescription drugs (NMUPD) is an urgent public health concern facing the United States. Young adults experiencing homelessness (YEH) are at increased risk of NMUPD; however, community estimates of NMUPD among YEH are sparse. This current study sought to understand patterns and correlates of NMUPD in a geographically heterogeneous sample of YEH recruited from seven cities across the United States.

METHODS

From June 2016 to July 2017, 1,426 YEH (aged 18-26) were recruited from seven cities (Houston, Los Angeles, Denver, Phoenix, New York City, St. Louis, San Jose). Participants provided information on substance use, mental health, trauma, and sexual-risk behaviors. Multivariable logistic regression was utilized to assess demographic, psychological, and behavioral correlates of self-reported past-month NMUPD and NMUPD types (i.e., prescription stimulant, sedative, and opioids).

RESULTS

Approximately 20% of participants reported past-month NMUPD. Almost 9% reported misusing prescription opioids, 8.7% misused prescription sedatives, and 6% misused prescription stimulants. Multivariable logistic regressions revealed unmet mental health needs were associated with sedative and stimulant misuse but not opioid misuse. Having suicidal thoughts was associated with opioid misuse but not sedative or stimulant misuse. Although no geographical differences emerged for stimulant and sedative misuse, youth from Denver, Phoenix, and San Jose were more likely to engage in opioid misuse relative to youth in Los Angeles.

CONCLUSIONS

These findings indicate that interventions designed to address NMUPD need to be multifaceted, designed to address other risk behaviors correlated with NMUPD, and target unmet mental health needs.

Knowledge and Attitudes About Pre-Exposure Prophylaxis Among Young Adults Experiencing Homelessness in Seven U.S. Cities

PURPOSE

Evidence suggests that young adults experiencing homelessness (YEH) are at elevated risk of HIV compared to housed youth. Given the limited research on pre-exposure prophylaxis (PrEP) awareness among YEH, this study examined their PrEP knowledge and attitudes.

METHODS

Data from a cross-sectional survey among YEH (ages 18-26) (n = 1,427) in seven U.S. cities were used to assess their knowledge and attitudes regarding PrEP to inform HIV prevention efforts.

RESULTS

Participants were primarily male youth of color. The mean age was 20.9years. While 66% felt at risk for HIV, only 14% strongly agreed that they try to protect themselves from getting infected with HIV. Most (84%) were eligible for PrEP based on risk, yet only 29% had knowledge of PrEP. Despite this, 59% reported they were likely/extremely likely to take PrEP. Access to free PrEP (55%), HIV testing (72%), healthcare (68%), and one-on-one (62%), and text messaging support (57%) were rated as very/extremely important for PrEP uptake and adherence.

CONCLUSIONS

The results of this study suggest missed opportunities to prevent new HIV infections among YEH. Efforts to increase PrEP uptake among this population should consider provider- and system-level interventions to increase PrEP awareness, decrease PrEP-associated healthcare costs, improve access to PrEP providers, and provide in-person and text messaging support.

Modifiable Risk Factors and Readiness to Change among Homeless Adults

Objectives: In this study, we examined the prevalence of modifiable health risk factors (eg, smoking, unsafe sexual practices, at-risk drinking, low fruit/vegetable consumption, inadequate physical activity, and overweight/obesity) and readiness to change among homeless adults in Oklahoma City, OK. A secondary aim was to examine the relationship between self-rated health and readiness to change. Methods: We examined readiness to change using "ladder of change" variables. We used linear regression models to predict self-rated health and readiness to change. Results: Participants (N = 581) were largely smokers (79%), consumed less than 5 fruit and vegetable servings per day (64%) and were overweight or obese (64%). Many participants were ready to change at-risk drinking (56%), fruit/vegetable consumption (74%), and overweight/obesity (74%). Regression analyses indicated that low fruit/vegetable consumption and physical activity were associated with lower self-rated health. Lower self-rated health was not significantly related to readiness to change any health risk factors. Conclusions: Among homeless adults, the prevalence of modifiable health risk factors was high, as was readiness to change. Research is needed to reduce individual risk factors in this understudied population.

Implications for PrEP Uptake in Young Adults Experiencing Homelessness: A Mixed Methods Study

Youth experiencing homelessness (YEH) have a high risk of contracting HIV; however, they remain relatively unreached by pre-exposure prophylaxis (PrEP)-based HIV prevention initiatives. We used a cross-sectional mixed-methods study to explore PrEP knowledge, interest, facilitators, and barriers among YEH. Young adults were recruited from agencies serving YEH in Houston, TX (n = 30) and Los Angeles, CA (n = 15) to participate in an electronic self-report survey and a semistructured interview. Survey results indicate that 68.2% of YEH had low or no prior knowledge of PrEP, though 63.7% reported interest in taking PrEP. Qualitative results revealed facilitators of PrEP use, including high PrEP acceptability and awareness, and supportive social networks. Several barriers emerged, including medication-related barriers, adherence, cost, access barriers, low perceived HIV risk, perceived stigma of PrEP use, and low PrEP awareness. Despite high PrEP acceptability, PrEP use among YEH remains low partly due to low PrEP awareness, low perceived HIV risk, and medical mistrust.

Predicting Sexual Behaviors Among Homeless Young Adults: Ecological Momentary Assessment Study

BACKGROUND

Homeless youth continue to be disproportionately affected by HIV compared with their housed peers, with prevalence rates as high as 13%. Yet, HIV prevention in this high-risk population has been only marginally effective.

OBJECTIVE

The aim of this study was to use ecological momentary assessments to examine real-time factors to determine the predictors of sexual activity among homeless youth.

METHODS

Youth experiencing homelessness aged between 18 and 24 years were recruited from a drop-in center in Houston, Texas, between August 2015 and May 2016. All the participants received a study-issued mobile phone that prompted brief ecological momentary assessments (EMAs) 5 times a day for 21 days. EMA items assessed near real-time sexual behaviors, cognitions, stress, affect, environmental factors, and environmental circumstances.

RESULTS

Participants (N=66) were predominantly male (41/66, 64%) and black (43/66, 66%) with a median age of 20 years. The mean number of EMAs completed by each participant was 45 out of 105 possible observations. During the study, 70% (46/66) of participants were sexually active and reported condomless sex in 102 of the 137 cases of sexual intercourse (74.5%). In total, 82% (38/46) of the youth who reported having sex during the 3 weeks of data collection also reported engaging in high-risk sexual activities, including having condomless sex (24/46, 53%), having multiple sexual partners on the same day (12/46, 26%), trading sex (7/46, 16%), and sharing needles while injecting drugs (1/46, 3%). Of those, 71% (27/38) were engaged in multiple sexual risk behaviors. The predictive model was based on observations from 66 subjects who reported 137 cases of sexual intercourse over 811 days; sexual orientation, race, mental health, drug use, and sexual urge were included as predictors in the parsimonious generalized linear mixed model selected on the basis of the Akaike information criterion. The estimated odds ratios (ORs) were notable for same-day drug use (OR 2.17, 95% CI 4.48-17.31; P<.001) and sexual urge (OR 1.44, 95% CI 1.60-11.28; P=.004). The performance of the risk estimator was satisfactory, as indicated by the value of 0.834 for the area under the receiver operating characteristic curve.

CONCLUSIONS

Real-time EMA data can be used to predict sexual intercourse among a sample of high-risk, predominately unsheltered homeless youth. Sexual urge and drug use accounts for increased odds of engaging in sexual activity on any given day. Interventions targeting sexual urge and drug use may help predict sexual activity among a population at high risk of HIV.

Addressing a Critical Gap in U.S. National Teen Pregnancy Prevention Programs: The Acceptability and Feasibility of Father-Based Sexual and Reproductive Health Interventions for Latino Adolescent Males

PURPOSE

The purpose of the research was to examine the feasibility and acceptability of a father-based sexual and reproductive health intervention designed to reduce sexual and reproductive (SRH) disparities and increase correct and consistent condom use among Latino adolescent males.

METHODS

The current study conducted in-depth semi-structured interviews with Latino father-son dyads (N=30) designed to elicit perspectives on communication regarding sex and condom use. In addition, the interview protocol included father-son preferences regarding paternal involvement in condom instruction and perceived obstacles and advantages of father direct involvement in education efforts designed to increase correct and consistent condom use among their adolescent sons. Three independent coders conducted both vertical and horizontal analyses of the data to identify emergent themes and reach theoretical saturation.

RESULTS

The main findings from this study suggest that Latino fathers can be impactful in shaping Latino adolescent male sexual decision-making and correct and consistent condom use. However, our data highlight that while both feasible and acceptable, Latino fathers identify needing additional support in how best to communicate and seek opportunities to master their own knowledge and skills regarding condom use and effective communication with their adolescent sons about sex.

CONCLUSIONS

Latino father-based interventions represent an acceptable and feasible option for building upon the recent success of U.S. national efforts to reduce teen pregnancy rates and STI disparities among Latino youth. However, there exists a need for father-based programs that will support Latino fathers in best educating their sons about condom use and better addressing their SRH. Ongoing national efforts to reduce Latino teen SRH disparities warrant the consideration of father-son interventions for Latino adolescent males in the United States.

Current Age, Age at First Sex, Age at First Homelessness, and HIV Risk Perceptions Predict Sexual Risk Behaviors among Sexually Active Homeless Adults

While HIV disproportionately impacts homeless individuals, little is known about the prevalence of HIV risk behaviors in the southwest and how age factors and HIV risk perceptions influence sexual risk behaviors. We conducted a secondary data analysis (n = 460) on sexually active homeless adults from a cross-sectional study of participants (n = 610) recruited from homeless service locations, such as shelters and drop-in centers, in an understudied region of the southwest. Covariate-adjusted logistic regressions were used to assess the impact of age at homelessness onset, current age, age at first sex, and HIV risk perceptions on having condomless sex, new sexual partner(s), and multiple sexual partners (≥4 sexual partners) in the past 12 months. Individuals who first experienced homelessness by age 24 were significantly more likely to report condomless sex and multiple sexual partners in the past year than those who had a later onset of their first episode of homelessness. Individuals who were currently 24 years or younger were more likely to have had condomless sex, new sexual partners, and multiple sexual partners in the past 12 months than those who were 25 years or older. Those who had low perceived HIV risk had lower odds of all three sexual risk behaviors. Social service and healthcare providers should consider a younger age at homelessness onset when targeting HIV prevention services to youth experiencing homelessness.

Drug use patterns and predictors among homeless youth: Results of an ecological momentary assessment

BACKGROUND

Alcohol and drug use is associated with significant morbidity and mortality and is highly prevalent among homeless youth. Ecological Momentary Assessments (EMA) have been used to examine the effect of urges on drug use, though not among homeless youth.

OBJECTIVES

We assessed the patterns of drug use and the correlation between real-time contextual factors and drug use using EMA collected daily. We identified predictors of drug use among a sample of homeless youth 18-25 years old in Houston, Texas.

METHODS

Homeless youth (n = 66, 62% male) were recruited from a drop-in center between September 2015 and May 2016. We used generalized linear mixed models and cross-validation methods to determine the best predictive model of drug use.

RESULTS

The overall drug use was high: 61% and 32% of participants reported using drugs or alcohol at least one day, respectively. Marijuana and synthetic marijuana use (i.e., Kush, K2, incense packs) were reported most frequently; 86% and 13% of the total drug use EMAs, respectfully. Drug use urge was reported on 26% of days and was the highest on drug use days. Drug use was predicted by discrimination, pornography use, alcohol use, and urges for drugs, alcohol, and to steal.

CONCLUSIONS

EMA can be used to predict drug use among homeless youth. Drug use treatment among homeless youth should address the role of experiencing discrimination, pornography and alcohol use, and urge management strategies on drug use. Research is needed to determine if EMA informed just-in-time interventions targeting these predictors can reduce use.

Promoting Parent-Child Sexual Health Dialogue with an Intergenerational Game: Parent and Youth Perspectives

OBJECTIVES

Sexual health discussions between parents and their preadolescent youth can delay sexual debut and increase condom and contraceptive use. However, parents frequently report being uncomfortable talking with their youth about sex, often reporting a lack of self-efficacy and skills to inform and motivate responsible decision making by youth. Intergenerational games may support parent-youth sexual health communication. The purpose of this study was to explore parent and youth perspectives on a proposed intergenerational game designed to increase effective parent-youth sexual health communication and skills training.

MATERIALS AND METHODS

Eight focus groups were conducted: four with parents (n=20) and four with their 11-14-year-old youth (n=19), to identify similarities and differences in perspectives on gaming context, delivery channel, content, and design (components, features, and function) that might facilitate dyadic sexual health communication.

RESULTS

Participants concurred that a sex education game could improve communication while being responsive to family time constraints. They affirmed the demand for an immersive story-based educational adventure game using mobile platforms and flexible communication modalities. Emergent themes informed the development of a features inventory (including educational and gaming strategies, communication components, channel, and setting) and upper-level program flow to guide future game development.

CONCLUSIONS

This study supports the potential of a game to be a viable medium to bring a shared dyadic sexual health educational experience to parents and youth that could engage them in a motivationally appealing way to meaningfully impact their sexual health communication and youth sexual risk behaviors.

Preparing Student Nurses as Parent-based Adolescent Sexual Health Educators: Results of a Pilot Study

OBJECTIVES

While health promotion and patient education are central to the scope of practice of professional nurses, they often feel ill-equipped to assume the role of sexual health educator and lack adequate knowledge and skills to effectively engage parents in adolescent sexual and reproductive health efforts.

DESIGN AND SAMPLE

Employing a mixed-methods study consisting of both pre- and post-test survey and exit interviews, a pilot study was conducted to assess the impact of implementing a parent-based adolescent sexual health intervention on baccalaureate nursing student outcomes (N = 31).

RESULTS

We found statistically significant improvements in student outcome expectancies of parenting strategies, barriers to sexual health communication, self-efficacy, and sexual health counseling experience. Using thematic content analysis of exit interview content, emerging themes were (1) need for increased sexual and reproductive health (SRH) preparation, (2) wanting greater experience and opportunity for involvement in nursing research, and (3) educational gaps in family-focused community public health.

CONCLUSIONS

Incorporating adolescent sexual health education into public health nursing clinical training can prepare nurses as parent-based adolescent sexual health educators, a core competency for nurses working with families in communities and across all health care delivery settings.

Exploring Contextual Factors of Youth Homelessness And Sexual Risk Behaviors: A Qualitative Study

CONTEXT

HIV disproportionately affects homeless youth, and interventions to date have had minimal success in reducing sexual risk behaviors in this population. Few qualitative studies have been conducted to provide insight into the influence of homelessness-related factors on sexual risk behaviors.

METHODS

A qualitative study with a quantitative component was conducted with a nonprobability sample of 64 homeless youth aged 14-24; participants were recruited from a variety of venues in Houston between October 2013 and March 2014. Thirteen focus group discussions were conducted; thematic analysis was used to identify themes related to HIV risk.

RESULTS

Participants were predominantly black (75%), sheltered (67%) and aged 18 or older (77%). Youth discussed how the circumstances of their homelessness and the struggle to meet their immediate needs led to behaviors and experiences that put them at risk for HIV. Three themes emerged: Homeless youth frequently engage in risky sexual behavior, sometimes as a way to cope with stress; they often trade sex, either voluntarily or involuntarily, for such necessities as money or a place to sleep; and many experienced childhood sexual victimization or have been victimized since becoming homeless. Youth also described how stress, stigma and self-reliance contributed to their involvement in HIV risk behaviors.

CONCLUSIONS

HIV prevention methods that target stress and stigma while respecting youths' self-reliance may help reduce sexual risk behaviors. Further research is needed to determine suitable behavioral change techniques to address these potentially modifiable factors.

Barriers and facilitators to shelter utilization among homeless young adults

Rates of shelter use among homeless youth are low compared to use of other supportive services, yet research on barriers to shelter use has been conducted in limited regions, specifically in West Coast or Midwest cities. Additionally, while studies have generally focused on barriers to shelter use, studies on what might facilitate shelter use are lacking. This study explores barriers and facilitators to shelter use among homeless young adults from a large city in the Southwest region. Focus groups were conducted with a diverse sample of 49 homeless young adults ages 18-24. Drawing on models of health service use, findings were categorized into two domains--attitudinal and access. Themes related to attitudinal barriers include stigma/shame and self-reliance/pride. Attitudinal facilitators include the desire to extricate themselves from street life and turn their lives in a new direction. Access-related themes include barriers such as a lack of shelters and services available to meet the needs of youth, adverse shelter conditions, staff attitudes that are not acceptable to youth, restrictive shelter rules, restrictive definitions of homelessness, and a desire to differentiate themselves from older homeless individuals. Certain characteristics or circumstances (e.g., being pregnant), having supportive others, and shelters' ability to connect them to other services emerged as access facilitators to shelter use. Implications for policymakers, service providers, and future research are discussed.

Mental illness and substance use problems in relation to homelessness onset

OBJECTIVES

The relationships among youth (≤ 24 years) versus adult (>24 years) homelessness onset, lifetime serious mental illness, and substance use problems is not well understood. We sought to explore these associations among 394 homeless adults, 124 of whom reported youth-onset homelessness.

METHODS

Covariate-adjusted logistic regression analyses evaluated the associations among homelessness onset, serious mental illness, and self-reported substance use problems.

RESULTS

Youth-onset homelessness was associated with greater likelihood of serious mental illness and sedative problems, and a lower likelihood of cocaine problems, in adjusted analyses (p values ≤ .04).

CONCLUSIONS

Serious mental illness and sedative problems may characterize homeless youth who are vulnerable to adulthood homelessness, although longitudinal cohort studies are needed to explicate temporal relations between variables.

Parent-based adolescent sexual health interventions and effect on communication outcomes: a systematic review and meta-analyses

CONTEXT

Parent-based adolescent sexual health interventions aim to reduce sexual risk behaviors by bolstering parental protective behaviors. Few studies of theory use, methods, applications, delivery and outcomes of parent-based interventions have been conducted.

METHODS

A systematic search of databases for the period 1998-2013 identified 28 published trials of U.S. parent-based interventions to examine theory use, setting, reach, delivery mode, dose and effects on parent-child communication. Established coding schemes were used to assess use of theory and describe methods employed to achieve behavioral change; intervention effects were explored in meta-analyses.

RESULTS

Most interventions were conducted with minority parents in group sessions or via self-paced activities; interventions averaged seven hours, and most used theory extensively. Meta-analyses found improvements in sexual health communication: Analysis of 11 controlled trials indicated a medium effect on increasing communication (Cohen's d, 0.5), and analysis of nine trials found a large effect on increasing parental comfort with communication (0.7); effects were positive regardless of delivery mode or intervention dose. Intervention participants were 68% more likely than controls to report increased communication and 75% more likely to report increased comfort.

CONCLUSIONS

These findings point to gaps in the range of programs examined in published trials-for example, interventions for parents of sexual minority youth, programs for custodial grandparents and faith-based services. Yet they provide support for the effectiveness of parent-based interventions in improving communication. Innovative delivery approaches could extend programs' reach, and further research on sexual health outcomes would facilitate the meta-analysis of intervention effectiveness in improving adolescent sexual health behaviors.

Exploring Parental Factors Related to Weight Management in Survivors of Childhood Central Nervous System Tumors

Childhood central nervous system tumor survivors (CCNSTS) are at risk for adverse health issues. Little research has been conducted to explore the role of parental factors in weight management to mitigate adverse health outcomes. We conducted 9 group interviews (n = 20) with CCNSTS, their parents, and health care providers to ascertain parental factors that may influence weight management practices in CCNSTS. Three main themes were identified: parenting style, parent–child connectedness, and food and physical activity (PA) environment. Although most parents adopted an authoritative parenting style related to diet and PA practices, some adopted a permissive parenting style. Participants expressed high levels of connection that may hinder the development of peer relationships and described the food and PA environments that promote or hinder weight management through parental modeling of healthy eating and PA and access to healthy food and activities. Weight management interventions for CCNSTS may experience greater benefit from using a family-focused approach, promoting positive food and PA environments, parental modeling of healthy eating and exercise, and partnering with youth to adopt weight management behaviors.

Contemporary research on parenting: conceptual, methodological, and translational issues

Researchers over the last decade have documented the association between general parenting style and numerous factors related to childhood obesity (e.g., children's eating behaviors, physical activity, and weight status). Many recent childhood obesity prevention programs are family focused and designed to modify parenting behaviors thought to contribute to childhood obesity risk. This article presents a brief consideration of conceptual, methodological, and translational issues that can inform future research on the role of parenting in childhood obesity. They include: (1) General versus domain specific parenting styles and practices; (2) the role of ethnicity and culture; (3) assessing bidirectional influences; (4) broadening assessments beyond the immediate family; (5) novel approaches to parenting measurement; and (6) designing effective interventions. Numerous directions for future research are offered.
