The role of housing stability in predicting social capital: Exploring social support and psychological integration as mediators for individuals with histories of homelessness and vulnerable housing.

Social capital is a collective asset important for individual and population well-being. Individuals who experience homelessness may face barriers in accessing social capital due to health challenges, small social networks, and social exclusion. Data from a 4-year longitudinal study was used to determine if housing stability predicted greater social capital and if this relationship was mediated by social support and psychological integration for a sample of 855 homeless and vulnerably housed participants living in three Canadian cities. Findings showed that housing stability was not associated with trust and linking social capital. However, higher levels of social support and psychological integration had a mediating effect on the association between housing stability and trust and linking social capital. These findings highlight the importance of social support and psychological integration as means of promoting social capital for people who experience homelessness and vulnerable housing. Social interventions for housed individuals with histories of homelessness may be an avenue to foster greater social capital by building relationships with neighbors and connections to community resources and activities.

Community Mental Health Services for Frequent Emergency Department Users: A Qualitative Study of Outcomes Perceived by Program Clients and Case Managers.

PURPOSE OF STUDY: This study aimed to investigate the perceived outcomes and mechanisms of change of a community mental health service combining system navigation and intensive case management supports for frequent emergency department users presenting with mental illness or addiction. PRIMARY PRACTICE SETTING: The study setting was a community mental health agency receiving automated referrals directly from hospitals in a midsize Canadian city for all individuals attending an emergency department two or more times within 30 days for mental illness or addiction. METHODOLOGY AND SAMPLE: Qualitative interviews with 15 program clients. Focus groups with six program case managers. Data were analyzed using pragmatic qualitative thematic analysis. RESULTS: Participants generally reported perceiving that the program contributed to reduced emergency department use, reduced mental illness symptom severity, and improved quality of life. Perceived outcomes were more mixed for outcomes related to addiction. Reported mechanisms of change emphasized the importance of positive working relationships between program clients and case managers, as well as focused efforts to develop practical skills. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Community mental health services including intensive case management for frequent emergency department users presenting with mental illness or addiction were perceived to effectively address client needs while reducing emergency department resource burden. Similar programs should emphasize the development of consistent and warm working relationships between program clients and case managers, as well as practical skills development to support client health and well-being.

Managing high-risk behaviours and challenges to prevent housing loss in permanent supportive housing: a rapid review.

Permanent supportive housing is an effective intervention for stably housing most people experiencing homelessness and mental illness who have complex support needs. However, high-risk behaviours and challenges are prevalent among this population and have the potential to seriously harm health and threaten housing tenures. Yet, the research on the relationship between high-risk issues and housing stability in permanent supportive housing has not been previously synthesized. This rapid review aimed to identify the housing-related outcomes of high-risk behaviours and challenges in permanent supportive housing settings, as well as the approaches used by agencies and residents to address them. A range of high-risk behaviours and challenges were examined, including risks to self (overdose, suicide/suicide attempts, non-suicidal self-injury, falls/fall-related injuries), and risks to multiple parties and/or building (fire-setting/arson, hoarding, apartment takeovers, physical/sexual violence, property damage, drug selling, sex trafficking). The search strategy included four components to identify relevant academic and grey literature: (1) searches of MEDLINE, APA PsycINFO, and CINAHL Plus; (2) hand searches of three journals with aims specific to housing and homelessness; (3) website browsing/searching of seven homelessness, supportive housing, and mental health agencies and networks; and (4) Advanced Google searches. A total of 32 articles were eligible and included in the review. Six studies examined the impacts of high-risk behaviours and challenges on housing tenancies, with overdose being identified as a notable cause of death. Twenty-six studies examined approaches and barriers to managing high-risk behaviours and challenges in PSH programs. These were categorized into eight types of approaches: (1) clinical, (2) relational/educational, (3) surveillant, (4) restrictive, (5) strategic, (6) design-based, (7) legal, and (8) self-defence. Consistent across all approaches was a lack of rigorous examination of their effectiveness. Further, some approaches that are legal, restrictive, surveillant, or strategic in nature may be used to promote safety, but may conflict with other program objectives, including housing stability, or resident empowerment and choice. Research priorities were identified to address the key evidence gaps and move toward best practices for preventing and managing high-risk behaviours and challenges in permanent supportive housing.

Parent-child relationship outcomes in a randomized controlled trial of housing first for indigenous and non-Indigenous parents experiencing homelessness, mental illness, and separation from their children.

OBJECTIVE: To examine the impacts of Housing First (HF) on parent-child relationships for Indigenous and non-Indigenous parents experiencing homelessness and mental illness. METHOD: Data on parent-child relationships were obtained through baseline and 18-month narrative interviews with parents (N = 43). Participants were randomly assigned to HF (N = 27) or treatment as usual (TAU; N = 16). Parent-child relationship changes were coded as positive or no change. Comparisons between HF and TAU groups were examined for Indigenous parents (N = 21) and non-Indigenous parents (N = 22). RESULTS: Parents in HF reported more positive changes, proportionally, in their relationships with their children, when compared with parents in the TAU group. Among Indigenous parents, proportionally more in HF (eight of 13 parents) reported positive changes in their relationships with their children, compared with those in TAU (one of eight parents). For non-Indigenous parents, however, those in HF (five of 14 parents) reported proportionally similar positive changes in relationships with their children to those in TAU (two of eight parents). Narratives of Indigenous parents in HF showed that they made considerable progress over 18 months in reconciling with their children. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Findings underscore the potential of HF to promote positive parent-child relationships. For Indigenous parents, HF programs that are designed, implemented, and staffed by Indigenous service-providers; guided by Indigenous worldviews; and employ culturally relevant and culturally safe practices are exemplars for understanding how HF programs can be adapted to positively impact parent-child relationships.

An Examination of the Effectiveness of Smoking Cessation Treatment Interventions for Individuals with Severe Mental Illness: A Pilot Randomized Controlled Trial.

To evaluate the effectiveness of two different smoking cessation interventions for individuals with severe mental illness. Study participants (N = 61) randomly assigned to the SC-R group (n = 29) were offered 24 weeks of no cost Nicotine Replacement Treatment (NRT); participants assigned to the SC + group (n = 32) were offered 24 weeks of no cost NRT plus two initial individual counselling sessions of motivational interviewing and weekly psychosocial group support for 24 weeks. At 6 months the smoking cessation outcome was 7% for the SC-R group and 14% for the SC + group, but there was no statistically significant difference between the groups. Both groups showed a significant decrease in the number of cigarettes smoked per day and significant improvement in physical health functioning. Clients with severe mental illness, high prevalence of co-occurring substance use and experience of homelessness, are both interested and able to quit smoking and reduce cigarette use.

Determinants of Hospital Use and Physician Services Among Adults With a History of Homelessness.

Background: People experiencing homelessness have diverse patterns of healthcare use. This study examined the distribution and determinants of healthcare encounters among adults with a history of homelessness. Methods: Administrative healthcare records were linked with survey data for a general cohort of adults with a history of homelessness and a cohort of homeless adults with mental illness. Binary and count models were used to identify factors associated with hospital admissions, emergency department visits and physician visits for comparison across the 2 cohorts. Results: During the 1-year follow-up period, a higher proportion of people in the cohort with a mental illness used any inpatient (27% vs 14%), emergency (63% vs 53%), or physician services (90% vs 76%) compared to the general homeless cohort. People from racialized groups were less likely use nearly all health services, most notably physician services. Other factors, such as reporting of a regular source of care, poor perceived general health, and diagnosed chronic conditions were associated with higher use of all health services except psychiatric inpatient care. Conclusion: When implementing interventions for patients with the greatest health needs, we must consider the unique factors that contribute to higher healthcare use, as well as the barriers to healthcare access.

Shelter Bans Among People Experiencing Homelessness: an Exploratory Study of Predictors in Two Large Canadian Datasets.

Emergency shelters are a core component of homeless service systems that address immediate basic needs. Service bans, which refer to temporary or permanent disallowances from a program or organization, are an underresearched phenomenon that can leave people experiencing homelessness without needed supports. This exploratory study examined the factors associated with shelter bans among people experiencing homelessness using secondary data from two Canadian studies: (1) a multisite randomized controlled trial of Housing First (At Home/Chez Soi Demonstration Project) and (2) a cross-sectional survey of youth experiencing homelessness across Canada (2019 Without a Home-National Youth Homelessness Survey). The two datasets were analyzed separately using logistic regression models with similar predictors to maximize the comparability of the results. Participants who experienced homelessness at an earlier age and had recent criminal justice system involvement were more likely to have shelter bans in both datasets. Impaired impulse control, more chronic medical conditions and living in Toronto were associated with increased likelihood of shelter bans in the At Home/Chez Soi dataset, whereas more adverse childhood experiences, physical violence victimization, engagement in survival sex behaviours and longer current episodes of homelessness were significant predictors of bans in the Without A Home dataset. Overall, the findings suggest that victimization and criminalization during homelessness may increase the risk of shelter loss from bans and further exclusion. The observed regional differences also highlight the potential limits of individual-level predictors. Further research is needed on shelter ban outcomes, as well as how capacity limits and organizational policies affect banning decisions.

Implementation of strengths model case management in seven mental health agencies in Canada: Direct-service practitioners' implementation experience.

RATIONALE: Implementation of strengths model case management is increasing internationally. However, few studies have focused on its implementation process, and none have specifically addressed the implementation experience of direct-service practitioners. OBJECTIVE: This paper presents factors that facilitate and impede the successful implementation of the strengths model, with a specific focus on practitioners who deliver the intervention directly to service recipients. METHOD: To address this objective, a qualitative study of seven mental health agencies that implemented the model was conducted, involving a combination of participant observations and qualitative semistructured interviews with case managers, team supervisors, and senior managers. Qualitative data were analyzed using open coding followed by axial coding. Finally, the findings were aligned with an adapted Consolidated Framework for Implementation Research. RESULTS: Implementation of the strengths model involved a significant change in practice for case management practitioners. The results confirm that at the beginning of implementation, the strengths model was perceived as complex and not always adaptable to on-the-ground realities. With time, and with support from management, ongoing training and supervision sessions, and reflection and discussion, practitioners regained feelings of competence and resistance to the model diminished. The use of the model's structured team-based supervision tools was fundamental to supporting the implementation process by enabling an interactive and concrete training approach. CONCLUSIONS: The more an approach leads to changes in daily practice and is perceived as complex, the more concrete support is needed during implementation. This article highlights the importance of attending to a practitioner's sense of personal effectiveness and competence in the adoption of new practices.

The Working Alliance as a Mediator Between Fidelity to Strengths Model Case Management and Client Outcomes.

Objective: The purpose of this study was to examine how the client­case manager working alliance in strengths model case management (SMCM) mediates the relationship between fidelity to the SMCM intervention and clients' quality of life, hope, and community functioning. Methods: In total, 311 people with severe mental illness, served at seven community mental health agencies in Canada, participated in the study. They were new to SMCM and participated in five structured interviews every 4.5 months for 18 months to measure the quality of the client­case manager working alliance and clients' quality of life, hope, and community functioning. The team-level SMCM fidelity scale was administered six times over 3 years. Ordinary least-squares path analysis was used to test simple mediation models. Results: Higher fidelity to SMCM was associated with better client outcomes indirectly through the working alliance. Higher SMCM fidelity predicted a stronger working alliance, which in turn predicted greater improvements in client quality of life (at 9 months and 18 months), hope (at 18 months), and community functioning (at 9 months). Conclusions: The results support the view that SMCM is an effective intervention. When the intervention was implemented as planned, it fostered stronger working alliances between clients and case managers and contributed to greater improvements in the quality of life, hope, and functioning of people with severe mental illness. The findings of this study highlight the value of ongoing monitoring of implementation fidelity to achieve high-fidelity interventions that may lead to positive client outcomes.

Association between fidelity to the strengths model of case management and client outcomes: A quasi-experimental study.

OBJECTIVE: Evidence concerning strengths model of case management (SMCM) remains mixed. This study aimed to test the hypotheses that higher fidelity to SMCM is associated with improved quality of life (QoL), hope, community participation, community functioning, more days of competitive employment and of independent living, and fewer days of hospitalization. METHODS: SMCM was implemented over a 3-year period, at seven sites in the Canadian provinces of Newfoundland and Labrador, Québec, and Ontario. Independent assessors visited 14 teams at the seven sites to evaluate fidelity at baseline and 6, 12, 18, 24, and 36 months later. Participants (N = 311) answered standardized questionnaires at 4.5-month intervals up to 18 months. Fidelity assessments were interpolated so they could be associated with questionnaire responses. Linear mixed-effects models and generalized linear models were estimated. RESULTS: Fidelity increased significantly, with all sites except one achieving or approaching good fidelity within 36 months. Fidelity was not significantly associated with any of the outcome measures, although all estimated directions of relationships were consistent with our hypotheses. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: In a pragmatic study of real-world implementation of the strengths model at seven sites, no statistically significant relationships between fidelity and outcomes were found. Low variation in fidelity across individuals, modest sample size, and limited ability to detect change over 18 months, may have contributed to these null findings.

Implementing the Strengths Model of Case Management: Assessing Practice Three Years After Initial Implementation.

While strengths approaches are important to recovery-oriented practice, implementation can be challenging. This study implemented the strengths model of case management (SMCM) in 11 CM teams and assessed the fidelity of delivery and staff perceptions of the model after 36 months using the SMCM fidelity scale and the Readiness Monitoring Tool. Paired sample t-tests assessed change in fidelity from baseline to 36 months. Adjusted regression analyses compared survey responses of direct and management staff. While fidelity ratings significantly improved across all domains, at 36 months they remained suboptimal in supervision practices and use of model tools. Staff perceptions were generally positive but consistently lower for front-line than management staff. Implementing SMCM into existing case management practice with good fidelity is feasible. However, clear support from management may strengthen staff motivation and delivery. A review of practice later in implementation can flag challenges for sustainability and guide implementation support.

Moving on trial: protocol for a pilot randomised controlled trial of models of housing and support to reduce risks of COVID-19 infection and homelessness.

BACKGROUND: It is estimated that around 160,000 households in Britain experience homelessness each year, although no definitive statistics exist. Between March and September 2020, as part of the initial 'Everyone In' government response to COVID-19 in England, 10,566 people were living in emergency accommodation and nearly 18,911 people had been moved into settled accommodation. However, some forms of temporary accommodation may not be suitable as shared facilities make it impossible for people to adhere to government guidelines to reduce the spread of COVID-19. METHODS: This is parallel group, pilot randomised controlled trial. The target is to recruit three local authorities, each of which will recruit 50 participants (thus a total of approximately 150 participants). Individuals are eligible if they are aged 18 and over, in a single-person homeless household, temporarily accommodated by the LA with recourse to public funds. Participants will be randomised to receive settled accommodation (intervention group) or temporary accommodation (control group). The intervention group includes settled housing such as Private Rented Sector (low and medium support), Social Housing (low and medium support), and Housing First (High support). The control group will maintain treatment as usual. The follow-up period will last 6 months. The primary outcome is to assess the feasibility of recruitment, retention, and acceptability of trial processes against progression criteria laid out in a traffic light system (green: all criteria are met, the trial should progress as designed in this pilot; amber: the majority of criteria are met and with adaptations to methods all criteria could be met; red: the minority of criteria are met and the pilot RCT should not proceed). Secondary outcomes include assessment of completeness of data collection at 3 and 6 months and percentage of participants consenting to data linkage, as well as a process evaluation and economic evaluation. DISCUSSION: This trial will address feasibility questions associated with progression to a fully powered effectiveness trial of models of housing to reduce risk of COVID-19 infection and homelessness. TRIAL REGISTRATION: ISRCTN69564614 . Registered on December 16, 2020.

Multi-trajectory group profiles of well-being and associated predictors among adults experiencing homelessness and mental illness: findings from the At Home/Chez Soi study, Toronto site.

PURPOSE: To conduct a multi-dimensional and time-patterned analysis to identify distinct well-being trajectory profiles over a 6-year follow-up period among adults experiencing homelessness and mental illness. METHODS: Data from 543 participants of the At Home Chez Soi study's Toronto site were examined over a 6-year follow-up period, including measures of quality of life, community functioning, housing stability, and substance use. Well-being trajectories were identified using Group-Based Trajectory Modelling. Multinomial regression was used to identify predictor variables that were associated with each well-being trajectory profile. RESULTS: Four well-being profiles were identified: low well-being, moderate well-being, good well-being, and high well-being. Factors associated with a greater likelihood of following a better well-being profile included receiving Housing First, reporting female gender and non-white ethnicity, having post-secondary studies, and reporting a high resilience level. Concurrently, factors associated with a lower likelihood of better well-being profiles were having a history of chronic homelessness, experiences of discrimination in the healthcare setting, having comorbid mental disorders and a high level of symptom severity, and reporting a history of traumatic brain injury and childhood adversity. CONCLUSIONS: Individuals experiencing homelessness follow distinct well-being profiles associated with their socio-demographic characteristics, health status, trauma history, resilience capabilities, and access to housing and support services. This work can inform integrated housing and support services to enhance the well-being trajectories of individuals experiencing homelessness. TRIAL REGISTRATION: At Home/Chez Soi trial was registered with ISRCTN, ISRCTN42520374, http://www.isrctn.com/ISRCTN42520374 .

A Qualitative Study of the Working Alliance in the Strengths Model of Case Management with People with Severe Mental Illness.

The purpose of this study was to examine clients' perceptions of the client-case manager working alliance in the context of receiving the Strengths Model of Case Management. Twenty people with severe mental illness, with a SMCM case manager, participated in semi-structured, qualitative interviews. Using first and second cycle coding, data were analyzed thematically. People in the study attributed personal life changes to their relationship with their case manager. They valued their case managers' flexibility and highlighted their work on a wide range of goals of their choosing. Case managers approached the SMCM intervention responsive to their clients' preferences and choices. The working alliance serves as a key element of the SMCM intervention. Clients describe the working alliance as helping to improve their lives. This study supports the implementation of SMCM with people with severe mental illness due to its focus on fostering a strong working alliance.

Experiences of LGBTQ Adults Who Have Accessed Emergency Shelters in a Large Urban City in Canada.

This study examines the experiences of adults who identify as LGBTQ (lesbian, gay, bisexual, transgender, queer) and who have accessed emergency shelters in an urban Canadian city. Twenty LGBTQ adults who were currently or formerly homeless participated in one qualitative interview. The interview protocol included questions on the participants' experiences accessing emergency shelters, with a focus on interactions with other emergency shelter residents. Data was analyzed using an iterative coding process. The results demonstrated that participants engage in various identity management strategies and encounter both positive and negative interactions with other emergency shelter residents. The results are discussed in terms of strategies to improve emergency shelter policies to be more inclusive of LGBTQ adults.

Mobile interventions targeting common mental disorders among pregnant and postpartum women: An equity-focused systematic review.

INTRODUCTION: Pregnant and postpartum women face major psychological stressors that put them at higher risk of developing common mental disorders, such as depression and anxiety. Yet, their limited access to and uptake of traditional mental health care is inequitable, especially during the COVID-19 pandemic. Mobile interventions emerged as a potential solution to this discontinued healthcare access, but more knowledge is needed about their effectiveness and impact on health equity. This equity-focused systematic review examined the effectiveness and equity impact of mobile interventions targeting common mental disorders among pregnant and postpartum women. METHODS AND RESULTS: We systematically searched MEDLINE, EMBASE, PsychINFO and 3 other databases, from date of database inception and until January 2021, for experimental studies on mobile interventions targeting pregnant and postpartum women. We used pooled and narrative synthesis methods to analyze effectiveness and equity data, critically appraised the methodological rigour of included studies using Cochrane tools, and assessed the certainty of evidence using the GRADE approach. Our search identified 6148 records, of which 18 randomized and non-randomized controlled trials were included. Mobile interventions had a clinically important impact on reducing the occurrence of depression (OR = 0.51 [95% CI 0.41 to 0.64]; absolute risk reduction RD: 7.14% [95% CI 4.92 to 9.36]; p<0.001) and preventing its severity perinatally (MD = -3.07; 95% CI -4.68 to -1.46; p<0.001). Mobile cognitive behavioural therapy (CBT) was effective in managing postpartum depression (MD = -6.87; 95% CI -7.92 to -5.82; p<0.001), whereas other support-based interventions had no added benefit. Results on anxiety outcomes and utilization of care were limited. Our equity-focused analyses showed that ethnicity, age, education, and being primiparous were characteristics of influence to the effectiveness of mobile interventions. CONCLUSION: As the COVID-19 pandemic has increased the need for virtual mental health care, mobile interventions show promise in preventing and managing common mental disorders among pregnant and postpartum women. Such interventions carry the potential to address health inequity but more rigorous research that examines patients' intersecting social identities is needed.

Validation of the Patient Generated Index for people with severe mental illness.

OBJECTIVE: The Patient Generated Index (PGI) is a personalized quality of life (QOL) measure. This secondary analysis examined its psychometric properties with people with severe mental illness. METHODS: Three hundred and eleven people with severe mental illness participated in structured interviews at baseline, 9 months, and 18 months. RESULTS: The PGI captured a range of self-defined life areas. PGI scores were correlated with measures of QOL, hope, and functioning, indicating concurrent (criterion) validity. The correlation with QOL, with the finding that PGI scores were significantly higher for people who were employed (n = 42) versus unemployed (n = 269) and for people without substance use disorder (n = 269) versus those with substance use disorder (n = 42), is indicative of construct validity. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The results support the suitability of the PGI as an idiographic measure for monitoring personalized QOL of people with severe mental illness.

Factors associated with higher healthcare costs in a cohort of homeless adults with a mental illness and a general cohort of adults with a history of homelessness.

BACKGROUND: Healthcare costs are disproportionately incurred by a relatively small group of people often described as high-cost users. Understanding the factors associated with high-cost use of health services among people experiencing homelessness could help guide service planning. METHODS: Survey data from a general cohort of adults with a history of homelessness and a cohort of homeless adults with mental illness were linked with administrative healthcare records in Ontario, Canada. Total costs were calculated using a validated costing algorithm and categorized based on population cut points for the top 5%, top 6-10%, top 11-50% and bottom 50% of users in Ontario. Multinomial logistic regression was used to identify the predisposing, enabling, and need factors associated with higher healthcare costs (with bottom 50% as the reference). RESULTS: Sixteen percent of the general homeless cohort and 30% percent of the cohort with a mental illness were in the top 5% of healthcare users in Ontario. Most healthcare costs for the top 5% of users were attributed to emergency department and inpatient service costs, while the costs from other strata were mostly for physician services, hospital outpatient clinics, and medications. The odds of being within the top 5% of users were higher for people who reported female gender, a regular medical doctor, past year acute service use, poor perceived general health and two or more diagnosed chronic conditions, and were lower for Black participants and other racialized groups. Older age was not consistently associated with higher cost use; the odds of being in the top 5% were highest for 35-to-49-year year age group in the cohort with a mental illness and similar for the 35-49 and ≥ 50-year age groups in the general homeless cohort. CONCLUSIONS: This study combines survey and administrative data from two cohorts of homeless adults to describe the distribution of healthcare costs and identify factors associated with higher cost use. These findings can inform the development of targeted interventions to improve healthcare delivery and support for people experiencing homelessness.

Does Housing Improve Health Care Utilization and Costs? A Longitudinal Analysis of Health Administrative Data Linked to a Cohort of Individuals With a History of Homelessness.

BACKGROUND: Individuals who are homeless have complex health care needs, which contribute to the frequent use of health services. In this study, we investigated the relationship between housing and health care utilization among adults with a history of homelessness in Ontario. METHODS: Survey data from a 4-year prospective cohort study were linked with administrative health records in Ontario. Annual rates of health encounters and mean costs were compared across housing categories (homeless, inconsistently housed, housed), which were based on the percentage of time an individual was housed. Generalized estimating equations were applied to estimate the average annual effect of housing status on health care utilization and costs. RESULTS: Over the study period, the proportion of individuals who were housed increased from 37% to 69%. The unadjusted rates of ambulatory care visits, prescription medications, and laboratory tests were highest during person-years spent housed or inconsistently housed and the rate of emergency department visits was lowest during person-years spent housed. Following adjustment, the rate of prescription claims remained higher during person-years spent housed or inconsistently housed compared with the homeless. Rate ratios for other health care encounters were not significant (P>0.05). An interaction between time and housing status was observed for total health care costs; as the percentage of days housed increased, the average costs increased in year 1 and decreased in years 2-4. CONCLUSIONS: These findings highlight the effects of housing on health care encounters and costs over a 4-year study period. The rate of prescription medications was higher during person-years spent housed or inconsistently housed compared with the homeless. The cost analysis suggests that housing may reduce health care costs over time; however, future work is needed to confirm the reason for the reduction in total costs observed in later years.

Overall and Gender-specific Associations between Dimensions of Adverse Childhood Experiences and Mental Health Outcomes among Homeless Adults: Associations Générales et Sexospécifiques Entre les Dimensions des Expériences Défavorables de L'enfance et les Résultats de Santé Mentale Chez les Adultes Sans Abri.

OBJECTIVE: The associations between adverse childhood experiences (ACEs) and psychopathology have been well-established in the general population. Research on ACEs in the homeless population has been limited. This study examined whether ACE exposure is associated with specific mental health outcomes among a national sample of homeless adults with mental illness and whether this association varies according to ACE dimension and gender. METHODS: This cross-sectional study utilized data from a national sample of 2,235 homeless adults with mental illness in Canada to evaluate their sociodemographic characteristics, exposure to ACEs, and mental health outcomes. Exploratory and confirmatory factor analyses were conducted to identify and confirm ACE dimensions (maltreatment, sexual abuse, neglect, divorce, and household dysfunction) from individual ACE items. Multivariable logistic regression was used to examine the associations between total ACE score and ACE dimensions with mental illness diagnoses and psychopathology severity. RESULTS: The mean total ACE score among all study participants was 4.44 (standard deviation [SD]: 2.99). Total ACE score was positively associated with several mental illness diagnoses and psychopathology severity. Unique associations were found between specific ACE dimensions and poor mental health outcomes. The prevalence of almost all ACEs was significantly higher among women. Yet, associations between several ACE dimensions and poor mental health outcomes existed uniquely among men. CONCLUSIONS: There are unique and gender-specific associations between specific ACE dimensions and mental health outcomes among homeless adults. Better understanding of the mechanisms underlying these associations is needed to inform screening, prevention, and treatment efforts, particularly given the very high prevalence of ACEs among this vulnerable and marginalized population.
