Attempting Randomized Housing First Research in a Community Context: Reflections on Failure.

The Housing First (HF) model of permanent supportive housing for individuals experiencing chronic homelessness has a strong evidence base that has largely been driven by researchers in the field of community psychology in partnership with community-based organizations. However, important gaps in the HF literature remain. Implementing rigorous research designs to further the evidence for HF requires immense resources to fund both the housing intervention and the research activities. In the absence of such resources, university-community partnerships may be established to integrate research within business-as-usual services and utilize existing housing units. This first person account presents a "post-mortem" exploration of an attempt to conduct a randomized trial of scattered-site and single-site approaches to HF within a community context from the perspectives of multiple stakeholders involved in the endeavor. Despite strengths of the research collaborative, the project did not come to completion due to a series of both insurmountable and avoidable barriers. Yet, the experience illuminated several potential challenges researchers and housing providers conducting work in this area may encounter, such as ever-changing homeless service system policies that may impact research and organizational procedures. Lessons learned and recommendations for preventing or overcoming systems-level barriers and potential challenges within the university-community partnership are described.

Systems change in the context of an initiative to scale up Housing First in Canada.

In this study, we examine changes in the homeless-serving system in the context of a training and technical assistance initiative to scale up Housing First (HF) in 6 Canadian communities. Based on qualitative data from focus groups and individual interviews with key stakeholders (k = 7, n = 35) and field notes gathered over a 3-year period (n = 146), we found 2 main system changes: (a) changes in the capacity of the service delivery system at multiple levels of analysis (from individual to policy) to implement HF, and (b) changes in the coordination of parts of the service delivery system and collaboration among local stakeholders to enhance HF implementation. These changes were facilitated or constrained by the larger context of evidence, climate, policy, and funding. The findings were discussed in terms of systems change theory and implications for transformative systems change in the mental health and homelessness sectors.

Navigating Complex Implementation Contexts: Overcoming Barriers and Achieving Outcomes in a National Initiative to Scale Out Housing First in Canada.

The scaling out of Housing First (HF) programs was examined in six Canadian communities, in which a multi-component HF training and technical assistance (TTA) was provided. Three research questions were addressed: (a) What were the outcomes of the TTA in terms of the development of new, sustained, or enhanced programs, and fidelity to the HF model? (b) How did the TTA contribute to implementation and fidelity? and (c) What contextual factors facilitated or challenged implementation and fidelity? A total of 14 new HF programs were created, and nine HF programs were sustained or enhanced. Fidelity assessments for 10 HF programs revealed an average score of 3.3/4, which compares favorably with other HF programs during early implementation. The TTA influenced fidelity by addressing misconceptions about the model, encouraging team-based practice, and facilitating case-based dialogue on site specific implementation challenges. The findings were discussed in terms of the importance of TTA for enhancing the capacities of the HF service delivery system-practitioners, teams, and communities-while respecting complex community contexts, including differences in policy climate across sites. Policy climate surrounding accessibility of housing subsidies, and use of Assertive Community Treatment teams (vs. Intensive Case Management) were two key implementation issues.

Understanding Systems Change in Early Implementation of Housing First in Canadian Communities: An Examination of Facilitators/Barriers, Training/Technical Assistance, and Points of Leverage.

We present interim findings of a cross-site case study of an initiative to expand Housing First (HF) in Canada through training and technical assistance (TTA). HF is an evidence-based practice designed to end chronic homelessness for consumers of mental health services. We draw upon concepts from implementation science and systems change theory to examine how early implementation occurs within a system. Case studies examining HF early implementation were conducted in six Canadian communities receiving HF TTA. The primary data are field notes gathered over 1.5 years and evaluations from site-specific training events (k = 5, n = 302) and regional network training events (k = 4, n = 276). We report findings related to: (a) the facilitators of and barriers to early implementation, (b) the influence of TTA on early implementation, and (c) the "levers" used to facilitate broader systems change. Systems change theory enabled us to understand how various "levers" created opportunities for change within the communities, including establishing system boundaries, understanding how systems components can function as causes of or solutions to a problem, and assessing and changing systems interactions. We conclude by arguing that systems theory adds value to existing implementation science frameworks and can be helpful in future research on the implementation of evidence-based practices such as HF which is a complex community intervention. Implications for community psychology are discussed.

Integrating Permanent Supportive Housing and Co-Occurring Disorders Treatment for Individuals Who Are Homeless.

OBJECTIVES: While permanent housing, addictions, and mental health treatment are often critical needs to achieve housing stability and community reintegration, few studies have systematically integrated them into a single comprehensive approach for people experiencing chronic homelessness. This pilot study examined the feasibility and preliminary outcomes of systematically integrating permanent supportive housing and an evidence-based co-occurring disorders intervention called Maintaining Independence and Sobriety Through Systems Integration, Outreach, and Networking (MISSION). METHODS: This single-group open pilot enrolled 107 people with co-occurring disorders experiencing chronic homelessness from two Massachusetts inner-city and rural areas. Enrolled subjects were interested in receiving permanent supportive housing along with 1 year of MISSION services. Data were collected through baseline and 6- and 12-month follow-up assessments. RESULTS: Participants (Mage = 49.52 years, SD = 10.61) were mostly male (76.6%), Caucasian (52.3%), and unemployed (86.0%), with an average of 8.34 years (SD = 8.01) of homelessness. Self-reported lifetime problems with anxiety (75.7%) and depression (76.6%) were common, as was use of alcohol (30.8%), cannabis (31.8%), and cocaine (15.9%). Almost all participants (95.3%) were placed into permanent housing, which took on average 42.6 days from enrollment (SD = 50.09). Among those placed, nearly 80% of the clients were able to retain housing through the end of the study. Overall retention was high, with 86.0% remaining in MISSION treatment until the end of the study. While there were no significant changes in rehospitalization, service utilization, or substance use, there were modest significant mental health symptom improvements from baseline to program completion. CONCLUSIONS: This pilot study suggests that co-occurring disorder interventions like MISSION are feasible to integrate with permanent supportive housing despite the somewhat differing philosophies, and preliminary data suggested substantial improvements in housing and modest improvements in mental health symptoms. While caution is warranted given the lack of a comparison group, these findings are consistent with other rigorous studies using MISSION among homeless individuals who did not receive permanent supportive housing.

Tenants with additional needs: when housing first does not solve homelessness.

BACKGROUND: At Home/Chez-Soi was a 24 month randomized controlled trial of Housing First (HF) conducted in five Canadian cities. AIMS: This article attempts to identify the characteristics of participants who experienced housing instability one year after entering HF. METHODS: Those defined as experiencing housing instability were housed <50% of the last 9 months of the first year, excluding time in institutions, unless they were housed 100% of the past 3 months. RESULTS: Only 13.5% of HF participants (n = 157/1162) met criteria for housing instability. Several variables were significant predictors of instability in between-group comparisons and multiple regression analyses: residence in Winnipeg, cumulative lifetime homelessness, percent of previous 3 months spent in jail, and community psychological integration; while residence in Moncton and a diagnosis of PTSD or panic disorder predicted stability. The predictive models were weak, identifying correctly only 3.8% of individuals that failed to achieve housing stability. CONCLUSIONS: It is not possible to predict confidently at baseline who will experience early housing instability in HF. There are certain individual characteristics that might be considered risk factors. Providing HF to all individuals who qualify for a HF program remains the most valid way to administer admission to housing.

Housing First for People With Severe Mental Illness Who Are Homeless: A Review of the Research and Findings From the At Home-Chez soi Demonstration Project.

OBJECTIVE: To provide a review of the extant research literature on Housing First (HF) for people with severe mental illness (SMI) who are homeless and to describe the findings of the recently completed At Home (AH)-Chez soi (CS) demonstration project. HF represents a paradigm shift in the delivery of community mental health services, whereby people with SMI who are homeless are supported through assertive community treatment or intensive case management to move into regular housing. METHOD: The AH-CS demonstration project entailed a randomized controlled trial conducted in 5 Canadian cities between 2009 and 2013. Mixed methods were used to examine the implementation of HF programs and participant outcomes, comparing 1158 people receiving HF to 990 people receiving standard care. RESULTS: Initial research conducted in the United States shows HF to be a promising approach, yielding superior outcomes in helping people to rapidly exit homelessness and establish stable housing. Findings from the AH-CS demonstration project reveal that HF can be successfully adapted to different contexts and for different populations without losing its fidelity. People receiving HF achieved superior housing outcomes and showed more rapid improvements in community functioning and quality of life than those receiving treatment as usual. CONCLUSIONS: Knowledge translation efforts have been undertaken to disseminate the positive findings and lessons learned from the AH-CS project and to scale up the HF approach across Canada.

Implementing Housing First Across Sites and Over Time: Later Fidelity and Implementation Evaluation of a Pan-Canadian Multi-site Housing First Program for Homeless People with Mental Illness.

This article examines later fidelity and implementation of a five-site pan-Canadian Housing First research demonstration project. The average fidelity score across five Housing First domains and 10 programs was high in the first year of operation (3.47/4) and higher in the third year of operation (3.62/4). Qualitative interviews (36 key informant interviews and 17 focus groups) revealed that staff expertise, partnerships with other services, and leadership facilitated implementation, while staff turnover, rehousing participants, participant isolation, and limited vocational/educational supports impeded implementation. The findings shed light on important implementation "drivers" at the staff, program, and community levels.

Housing First: exploring participants' early support needs.

BACKGROUND: Housing First has become a popular treatment model for homeless adults with mental illness, yet little is known about program participants' early experiences or trajectories. This study used a mixed methods design to examine participant changes in selected domains 6 months after enrollment in a Canadian field trial of Housing First. METHODS: The study sample included 301 participants receiving the Housing First intervention at the Toronto site of the At Home/Chez Soi project. This study used a pre-post design to compare quantitative 6-month outcome data to baseline values in key domains and multivariate regression to identify baseline demographic, clinical or service use variables associated with observed changes in these domains. In addition, qualitative data exploring participant and service provider perspectives and experiences was collected via stakeholder interviews and focus groups, and analyzed using thematic analysis. RESULTS: The majority (60 to 72%) of participants followed the expected trajectory of improvement, with the remaining experiencing difficulties in community integration, mental health symptom severity, substance use, community functioning and quality of life 6 months after program enrollment. Diagnosis of psychotic disorder was associated with a reduction in quality of life from baseline to 6-months, while substance use disorders were associated with reduced mental illness symptoms and substance use related problems and an improvement in quality of life. Participants housed in independent housing at 6-months had greater improvements in community integration and quality of life, and greater reduction in mental illness symptoms, compared to those not independently housed. The quality of the working alliance was positively associated with improvements in physical and psychological community integration and quality of life. Qualitative data provided a unique window into the loneliness and isolation experienced by Housing First participants, as well as problems related to substance use and a need for life skills training and support. CONCLUSIONS: Additional strategies can help support Housing First participants in the early stages of program participation and address potential causes of early difficulties, including lack of life skills and social isolation. This study highlights the importance of early and ongoing evaluation, monitoring and program adaptations to address consumer support needs.

Implementing housing first in rural areas: pathways Vermont.

The benefits of Pathways Housing First in addressing chronic homelessness for persons with severe mental illness have been well established. However, the implementation and effectiveness of such programs in rural areas has yet to be examined. We described the model's adaptations in Vermont, including the use of hybrid assertive community treatment-intensive case management teams, which consisted of service coordinators with geographically based caseloads (staff/client ratio of 1:20) and regional multidisciplinary specialists. The program's innovative and widespread inclusion of technology into operations facilitated efficiency and responsiveness, and a pilot telehealth initiative supplemented in-person client visits. The program achieved a housing retention rate of 85% over approximately 3 years, and consumers reported decreased time spent homeless, demonstrating that program adaptations and technological enhancements were successful.

Health and wellness photovoice project: engaging consumers with serious mental illness in health care interventions.

People with serious mental illnesses (SMI) are at increased risk for cardiovascular disease and premature mortality. We used photovoice in two supportive housing agencies to engage consumers with SMI to inform the implementation of health care interventions. Sixteen consumers participated in six weekly sessions in which they took photographs about their health and discussed the meanings of these photographs in individual interviews and group sessions. We identified several implementation themes related to consumers' preferences. Peer-based approaches were preferred more than clinician-driven models. Participants expressed a desire to learn practical skills through hands-on activities to modify health behaviors. Consumers expressed a desire to increase their physical activity. Participants revealed in their photographs and narratives the important role that communities' food environments play in shaping eating habits. In this article, we show how photovoice can generate valuable community knowledge to inform the translation of health care interventions in supportive housing agencies.

Housing stability and recovery among chronically homeless persons with co-occuring disorders in Washington, DC.

Pathways Housing First provides access to housing, support, and treatment services to clients having the most complex needs-persons who have been homeless for at least 5 years and have both a psychiatric disability and substance dependency. In a 2-year Housing and Urban Development-funded demonstration project in Washington, DC, in 2007 and 2008, we observed promising outcomes in housing retention and reductions in psychiatric symptoms, alcohol use, and demand for intensive support services. The program is designed to be fiscally self-sustaining through extant public disability benefits for housing, treatment, and support services. This approach shows strong support for first providing a permanently supported housing solution for chronically homeless and severely disabled individuals in need of housing and treatment of co-occurring disorders.

Health and social outcomes in the Housing First model: Testing the theory of change.

Background: Homelessness continues to grow globally. The Housing First (HF) model offers immediate access to housing and support services without preconditions and has a growing body of evidence documenting its effectiveness at ending homelessness. HF has a robust theory of change that hypothesizes how unique program components (i.e., immediate access to housing, separation of services from housing, client choice, etc.) drive positive social and health changes over time. We advance the understanding of how HF causes client improvement by empirically testing this program's theory of change. Methods: Using a unique longitudinal quantitative data from the large Canadian At Home/Chez Soi Housing First trial we used path analysis to test the theory of change for Quality of Life, Crisis related events or service utilization, and Recovery.  Program pathways and health and social outcomes were measured at enrolment, 6-, 12- and 24-months post-enrolment. Findings: Most hypothesized pathways were confirmed with path analysis.  Confirmed pathways for two outcomes- Quality of Life (QOL) and Recovery - were similar. Health and social consultations at enrolment, health status at 6- and 12-months post enrolment, and social connectedness at 12-months were important predictors of the 24-month outcomes of Quality of Life and Recovery, but not for Crisis related events or service utilization. Interpretation: This analysis directly responds to recent calls for more empirical evidence about intervention mechanisms. Ensuring linkages to health and social service consultations for clients, supporting clients' engagement with family and community, and enabling clients to improve or maintain good health will drive better longer term client outcomes within Housing First.

Harm reduction outcomes and practices in Housing First: A mixed-methods systematic review.

BACKGROUND: Harm reduction is a central tenet of Housing First. As the intervention has been shown to stably house people experiencing chronic homelessness across the lifespan with complex behavioural health needs, it is critical to understand the harm reduction outcomes and practices in Housing First. METHODS: A systematic review following PRISMA guidelines was conducted of five databases: PsycINFO, MEDLINE, Embase, CINAHL, and Google Scholar. Harm reduction outcomes and practices in Housing First were examined in four domains: substance-related harms, viral health, sexual health, and harm reduction service use. RESULTS: A total of 35 articles were included in the review, 23 of which examined harm reduction outcomes and 12 of which investigated harm reduction practices in Housing First. Harm reduction outcome studies focused mostly on nonspecific substance use problems, with Housing First being found to have minimal effects in this domain. More severe harms, such as delirium tremens and substance use-related deaths, have been minimally explored, though preliminary evidence is promising. Viral health, sexual health, and harm reduction service use outcomes were the focus of few studies. Research on harm reduction practices highlighted that Housing First providers experience both flexibility and ambiguity in their work using a harm reduction approach, and the importance of empathetic working relationships for engagement in harm reduction work. CONCLUSIONS: Harm reduction outcomes in Housing First remain underexamined and any conclusions of the intervention's impacts in this domain would be premature. Effective harm reduction practices in Housing First require strong working relationships between staff and tenants.

Knowledge translation and implementation of housing first in Canada: A qualitative assessment of capacity building needs for an evidence-based program.

We examined communities' expressed needs for capacity building in the implementation of Housing First (HF) for persons experiencing homelessness. The findings are based on thematic analyses of qualitative data obtained from participants (n = 77) in 11 focus groups conducted in seven Canadian cities. We identified capacity building needs in the areas of training (e.g., HF principles, clinical services, landlord engagement) and technical assistance (e.g., intake coordination, client prioritization, fidelity assessment). These findings were used to tailor training and technical assessment (TTA) to the stages of HF implementation in these cities. Limitations and implications for future theory, research, and practice are discussed.

Homelessness, mental illness, and criminal activity: examining patterns over time.

This study examined whether street homelessness, sheltered homelessness, and the severity of psychological symptoms predicted non-violent and violent crime among 207 mentally ill participants who were homeless at baseline. Participants were interviewed at 9 time points over 4 years. Hierarchical linear modeling (HLM) was used to examine whether changes in homelessness status and symptom severity predicted changes in criminal activity over time. Results indicated that homelessness both on the streets and in shelters and psychological symptom severity predicted increases in non-violent crime. Sheltered homelessness and symptom severity predicted increases in violent crime, although street homelessness did not. A separate mediational analysis with 181 participants showed that the relationship between diagnosis of a psychotic disorder and both non-violent and violent criminal activity was partially mediated through the severity of psychotic symptoms. Implications for research and intervention are discussed.

The housing first technical assistance and training (HFTAT) implementation strategy: outcomes from a mixed methods study of three programs.

BACKGROUND: This paper discusses the initial testing of the Housing First Training and Technical Assistance (HFTAT) Program, a multifaceted, distance-based strategy for the implementation of the Housing First (HF) supportive housing model. HF is a complex housing intervention for serving people living with serious mental illness and a substance use disorder that requires significant individual- and structural-level changes to implement. As such, the HFTAT employs a combined training and consultation approach to target different levels of the organization. Training delivered to all organizational staff focuses on building individual knowledge and uses narrative storytelling to overcome attitudinal implementation barriers. Consultation seeks to build skills through technical assistance and fidelity audit and feedback. METHOD: We employed a mixed method design to understand both individual-level (e.g., satisfaction with the HFTAT, HF knowledge acquisition and retention, and HF acceptability and appropriateness) and structural-level (e.g., fidelity) outcomes. Quantitative data were collected at various time points, and qualitative data were collected at the end of HFTAT activities. Staff and administrators (n = 113) from three programs across three states participated in the study. RESULTS: Satisfaction with both training and consultation was high, and discussions demonstrated both activities were necessary. Flexibility of training modality and narrative storytelling were particular strengths, while digital badging and the community of practice were perceived as less valuable because of incompatibilities with the work context. HF knowledge was high post training and retained after 3-month follow-up. Participants reported training helped them better understand the model. Attitudes toward evidence-based interventions improved over 6 months, with qualitative data supporting this but demonstrating some minor concerns related to acceptability and appropriateness. Fidelity scores for all programs improved over 9 months. CONCLUSION: The HFTAT was a well-liked and generally useful implementation strategy. Results support prior research pointing to the value of both (a) multifaceted strategies and (b) combined training and consultation approaches. The study also provides evidence for narrative storytelling as an approach for changing attitudinal implementation barriers. The need for compatibility between specific elements of an implementation strategy and the work environment was also observed.

ACT team members' responses to training in recovery-oriented practices.

To further our understanding of the consequences of training in recovery principles and practices, this study examined ACT team workers' responses to a state-wide recovery training initiative. Analysis of trainees' comments revealed ten themes expressing endorsement of or difficulties with recovery-oriented practices. Trainees' comments supporting a recovery orientation described service recipients in holistic terms and described using various techniques to attain "client-centered" goals. Recovery-oriented tasks that posed dilemmas for trainees were: reconciling system-centered goals with recipients' goals, establishing collaborative relationships with recipients, and using a recovery orientation with recipients who are in crisis and/or who "don't admit to being mentally ill."

Further Validation of the Pathways Housing First Fidelity Scale.

OBJECTIVE: This study examined whether Housing First fidelity ratings correspond to program operation descriptions from administrative data and predict client outcomes. METHODS: A multisite, randomized controlled trial (At Home/Chez Soi) in five Canadian cities included two assessments of 12 programs over two years. Outcomes for 1,158 clients were measured every six months. Associations between fidelity ratings and administrative data (Spearman correlations) and participant outcomes (mixed-effects modeling) were examined. RESULTS: Fidelity ratings were generally good (mean ± SD=136.6 ± 10.3 out of a possible range of 38-152; 87% of maximum value). Fidelity was significantly associated with three of four measures of program operation, with correlations between .55 and .60. Greater program fidelity was associated with improvement in housing stability, community functioning, and quality of life. CONCLUSIONS: Variation in program fidelity was associated with operations and outcomes, supporting scale validity and intervention effectiveness. These findings reinforced the value of using fidelity monitoring to conduct quality assurance and technical assistance activities.

A Multiple-City RCT of Housing First With Assertive Community Treatment for Homeless Canadians With Serious Mental Illness.

OBJECTIVE: Housing First with assertive community treatment (ACT) is a promising approach to assist people with serious mental illness to exit homelessness. The article presents two-year findings from a multisite trial on the effectiveness of Housing First with ACT. METHODS: The study design was a randomized controlled trial conducted in five Canadian cities. A sample of 950 participants with serious mental illness who were absolutely homeless or precariously housed were randomly assigned to receive either Housing First with ACT (N=469) or treatment as usual (N=481). RESULTS: Housing First participants spent more time in stable housing than participants in treatment as usual (71% versus 29%, adjusted absolute difference [AAD]=42%, p<.01). Compared with treatment-as-usual participants, Housing First participants who entered housing did so more quickly (73 versus 220 days, AAD=146.4, p<.001), had longer housing tenures at the study end-point (281 versus 115 days, AAD=161.8, p<.01), and rated the quality of their housing more positively (adjusted standardized mean difference [ASMD]=.17, p<.01). Housing First participants reported higher quality of life (ASMD=.15, p<.01) and were assessed as having better community functioning (ASMD=.18, p<.01) over the two-year period. Housing First participants showed significantly greater gains in community functioning and quality of life in the first year; however, differences between the two groups were attenuated by the end of the second year. CONCLUSIONS: Housing First with ACT is an effective approach in various contexts for assisting individuals with serious mental illness to rapidly exit homelessness.
