The article reports empirical outcomes of an ongoing transdisciplinary participatory community action research project that implements behavioral activation in homeless shelters. The overall goal of this Project is twofold: (1) to improve psychosocial functioning of shelter residents and enhance their opportunities to overcome homelessness; and (2) to enhance civic development of service-learning students who assist in Project implementation. Two studies are reported, representing these goals. Study 1 found that residents of a men's shelter (n = 892), women's shelter (n = 433), and transitional housing (n = 40) perceived behavioral activation sessions as immediately beneficial (i.e., important, meaningful, worthy of repeating, and enjoyable), and over the course of shelter stay, they perceived behavioral activation as contributing to their hope, empowerment/self-sufficiency, quality of life, purpose/meaning in life, wellbeing, social support, shelter social climate, and relationships with staff. Quantitative findings are supported by qualitative data (comments by residents on forms). Study 2, which replicates and extends past research on civic-development in service-learning students, used a new quasi-experimental design to compare service-learning students (n = 41) in an interdisciplinary course on homelessness versus non-service-learning students (n = 16) in a psychology course. Service-learning students showed pre- to post-semester improvements in community service self-efficacy, decreases in stigmatizing attitudes, and increases in awareness of privilege and oppression, but students not engaged in service-learning did not show these civic-related changes. These quantitative results are supported by qualitative data (written reflections by students). Results and implications are discussed within the context of the concept of psychopolitical validity.

Background: Justice-involved youth are especially vulnerable to mental health distress, substance misuse, and risky sexual activity, amplifying the need for evidence-based programs (EBPs). Yet, uptake of EBPs in the justice system is challenging because staff training is costly in time and effort. Hence, justice-involved youth experience increasing health disparities despite the availability of EBPs. Objective: To counter these challenges, this study develops and pilot-tests a prototype of a technology-based training tool that teaches juvenile justice staff to deliver a uniquely tailored EBP for justice-involved youth—PHAT (Preventing HIV/AIDS Among Teens) Life. PHAT Life is a comprehensive sex education, mental health, and substance use EBP collaboratively designed and tested with guidance from key stakeholders and community members. The training tool addresses implementation barriers that impede uptake and sustainment of EBPs, including staff training and support and implementation costs. Methods: Staff (n=11) from two juvenile justice settings pilot-tested the technology-based training tool, which included five modules. Participants completed measures of HIV and sexually transmitted infection (STI) knowledge, sex education confidence, and implementation outcomes such as training satisfaction, adoption, implementation, acceptability, appropriateness, and sustainability. PHAT Life trainers assessed fidelity through two activity role plays participants submitted upon completing the training modules. Results: Participants demonstrated increases in HIV and STI knowledge (t10=3.07; P=.01), and were very satisfied (mean 4.42, SD 0.36) with the training tool and the PHAT Life curriculum. They believed that the training tool and curriculum could be adopted, implemented, and sustained within their settings as an appropriate and acceptable intervention and training. Conclusions: Overall, the results from this pilot test demonstrate feasibility and support continuing efforts toward completing the training tool and evaluating it within a fully powered randomized controlled trial. Ultimately, this study will provide a scalable option for disseminating an EBP and offers a more cost-effective and sustainable way to train staff in an EBP.

Youth experiencing homelessness (YEH) are infrequently included in the development, organization, and provision of homelessness-related services. This lack of youth voice and services tailored for their expressed needs can lead to underutilization of services, dissatisfaction, and poor outcomes. Photovoice, a participatory research method, has been used to empower persons from marginalized populations and to provide a platform for them to share their voices. This photovoice project partnered with six YEH (18-20 years old). Participants worked together, with the support of two group facilitators, to take photographs, identify themes, write narratives that best represented their lived experience, and share their concerns and ideas for the community. Photos and narratives were shared with decisionmakers at community-based showings. Attendees of the showings anecdotally reported having an increased awareness of YEH issues. The showings served as a catalyst in the community to address the challenges of YEH. Recommendations for research and practice are provided.
