A Longitudinal Exploration of How Connections to Staff Facilitate Efficacy and Service Use in Drop-in Centers Serving Youth Experiencing Homelessness.

INTRODUCTION: Youth experiencing homelessness (YEH) benefit from a variety of services to meet their immediate and long-term needs. Drop-in centers are a popular service venue used by YEH. However, the mechanisms responsible for engaging youth in drop-in services are not clear. The current study uses longitudinal data to explore the role of positive staff relationships in increasing youths' knowledge and efficacy to access and subsequently use drop-in center services. METHODS: 731 youth (Mage = 21.8, SD = 2.2, 25.1% female) accessing services at three drop-in centers in Los Angeles, California participated in the study. Surveys were completed at baseline, 1-month, and 3-months later. Path models examined the direct effect of positive relationships with adult staff on service use at the 3-month follow-up, and the indirect effect of service knowledge (assessed at the 1-month follow-up). RESULTS: The direct effect model showed that positive staff relationships at baseline were significantly associated with number of services used at the 3-month follow-up (aIRR = 1.24, 95% CI: 1.00, 1.54). Positive staff relationships were also associated with greater service knowledge at 1-month (b = 0.93, p < 0.001), which in turn was associated with greater service use at 3-months (IRR = 1.15, 95% CI: 1.04, 1.28). The indirect effect of service knowledge was significant (b = 0.13, p = 0.02), suggesting that the association between positive staff relationships and service use was completely mediated by service knowledge. CONCLUSIONS: The current study adds to the literature by demonstrating that positive relationships with staff lead to increased service use by increasing youths' knowledge and efficacy to access services. Efforts should be made to develop positive relationships with YEH in order to engage them in essential services needed to exit homelessness.

MYPATH: A novel mindfulness and yoga-based peer leader intervention to prevent violence among youth experiencing homelessness.

Young adults experiencing homelessness (YAEH) are at elevated risk for violence victimization and perpetration. However, there are no evidence-based violence prevention interventions for homeless populations. This study is an evaluation of a novel mindfulness-based peer-leader intervention designed to reduce violence and improve mindfulness in YAEH. A social network of YAEH receiving services at a drop-in agency was recruited in Summer 2018 (n = 106) and peer-leaders identified at baseline (n = 12). Peer leaders were trained in mindfulness and yoga skills during a 1-day intensive workshop and seven 1-h weekly follow-up workshops and encouraged to share their knowledge with in-network peers. Postintervention data were collected 2 and 3 months after baseline. Two one-way repeated-measures analyses of variance (ANOVAs) tested differences in means for mindfulness and fighting. ANOVA models showed significant increases in group mean mindfulness F(2, 110) = 3.42, p < 0.05 and significant decreases in group mean violent behavior F(2, 112) = 5.23, p < 0.01 at the network level. Findings indicate a network-based, peer-leader model can be effective for influencing complex, socially conditioned attitudes and behaviors among YAEH. Additional advantages of the peer-leader model include relatively few direct-service person-hours required from providers and convenience to participants able practice skills in their relevant social contexts.

A Peer-Led, Artificial Intelligence-Augmented Social Network Intervention to Prevent HIV Among Youth Experiencing Homelessness.

BACKGROUND: Youth experiencing homelessness (YEH) are at elevated risk of HIV/AIDS and disproportionately identify as racial, ethnic, sexual, and gender minorities. We developed a new peer change agent (PCA) HIV prevention intervention with 3 arms: (1) an arm using an artificial intelligence (AI) planning algorithm to select PCAs; (2) a popularity arm, the standard PCA approach, operationalized as highest degree centrality (DC); and (3) an observation-only comparison group. SETTING: A total of 713 YEH were recruited from 3 drop-in centers in Los Angeles, CA. METHODS: Youth consented and completed a baseline survey that collected self-reported data on HIV knowledge, condom use, and social network information. A quasi-experimental pretest/posttest design was used; 472 youth (66.5% retention at 1 month postbaseline) and 415 youth (58.5% retention at 3 months postbaseline) completed follow-up. In each intervention arm (AI and DC), 20% of youth was selected as PCAs and attended a 4-hour initial training, followed by 7 weeks of half-hour follow-up sessions. Youth disseminated messages promoting HIV knowledge and condom use. RESULTS: Using generalized estimating equation models, there was a significant reduction over time (P < 0.001) and a significant time by AI arm interaction (P < 0.001) for condomless anal sex act. There was a significant increase in HIV knowledge over time among PCAs in DC and AI arms. CONCLUSIONS: PCA models that promote HIV knowledge and condom use are efficacious for YEH. Youth are able to serve as a bridge between interventionists and their community. Interventionists should consider working with computer scientists to solve implementation problems.

Exchange and Survival Sex, Dating Apps, Gender Identity, and Sexual Orientation Among Homeless Youth in Los Angeles.

We estimated the association between gender and sexual identities, and engagement in exchange and survival sex and seeking these partners via dating apps or websites, within a sample of homeless youth. In 2017, 253 homeless youth were interviewed from three different drop-in centers in Los Angeles. Multivariable regression analyses assessed associations between gender/sexual identity, and exchange and survival sex, adjusting for demographic characteristics. Sexual minority (43.6%) and gender minority (12.1%) youth reported elevated rates of exchange sex compared to cisgender heterosexual youth. Twenty-three percent of youth who engaged in survival or exchange sex used dating apps or websites to find partners. Exchange sex was associated with having recent HIV positive sex partners. Reporting an HIV positive partner and a relatively high number of sexual partners were significant predictors of engaging in survival sex. Programs and interventions for homeless youth should address engagement with technology and exchange and survival sex, and should respond to the unique needs of sexual and gender minority homeless youth.
