Abstract
Background Adequate housing is a basic human right. The many millions of people experiencing homelessness (PEH) have a lower life expectancy and more physical and mental health problems. Practical and effective interventions to provide appropriate housing are a public health priority. Objectives To summarise the best available evidence relating to the components of case-management interventions for PEH via a mixed methods review that explored both the effectiveness of interventions and factors that may influence its impact. Search Methods We searched 10 bibliographic databases from 1990 to March 2021. We also included studies from Campbell Collaboration Evidence and Gap Maps and searched 28 web sites. Reference lists of included papers and systematic reviews were examined and experts contacted for additional studies. Selection Criteria We included all randomised and non-randomised study designs exploring case management interventions where a comparison group was used. The primary outcome of interest was homelessness. Secondary outcomes included health, wellbeing, employment and costs. We also included all studies where data were collected on views and experiences that may impact on implementation. Data Collection and Analysis We assessed risk of bias using tools developed by the Campbell Collaboration. We conducted meta-analyses of the intervention studies where possible and carried out a framework synthesis of a set of implementation studies identified by purposive sampling to represent the most 'rich' and 'thick' data. Main Results We included 64 intervention studies and 41 implementation studies. The evidence base was dominated by studies from the USA and Canada. Participants were largely (though not exclusively) people who were literally homeless, that is, living on the streets or in shelters, and who had additional support needs. Many studies were assessed as having a medium or high risk of bias. However, there was some consistency in outcomes across studies that improved confidence in the main findings. Case Management and Housing Outcomes Case management of any description was superior to usual care for homelessness outcomes (standardised mean difference [SMD] = -0.51 [95% confidence interval [CI]: -0.71, -0.30]; p < 0.01). For studies included in the meta-analyses, Housing First had the largest observed impact, followed by Assertive Community Treatment, Critical Time Intervention and Intensive Case Management. The only statistically significant difference was between Housing First and Intensive Case Management (SMD = -0.6 [-1.1, -0.1]; p = 0.03) at ≥12 months. There was not enough evidence to compare the above approaches with standard case management within the meta-analyses. A narrative comparison across all studies was inconclusive, though suggestive of a trend in favour of more intensive approaches. Case Management and Mental Health Outcomes The overall evidence suggested that case management of any description was not more or less effective compared to usual care for an individual's mental health (SMD = 0.02 [-0.15, 0.18]; p = 0.817). Case Management and Other Outcomes Based on meta-analyses, case management was superior to usual care for capability and wellbeing outcomes up to 1 year (an improvement of around one-third of an SMD; p < 0.01) but was not statistically significantly different for substance use outcomes, physical health, and employment. Case Management Components For homelessness outcomes, there was a non-significant trend for benefits to be greater in the medium term (≤3 years) compared to long term (>3 years) (SMD = -0.64 [-1.04, -0.24] vs. -0.27 [-0.53, 0]; p = 0.16) and for in-person meetings in comparison to mixed (in-person and remote) approaches (SMD = -0.73 [-1.25,-0.21]) versus -0.26 [-0.5,-0.02]; p = 0.13). There was no evidence from meta-analyses to suggest that an individual case manager led to better outcomes then a team, and interventions with no dedicated case manager may have better outcomes than those with a named case manager (SMD = -0.36 [-0.55, -0.18] vs. -1.00 [-2.00, 0.00]; p = 0.02). There was not enough evidence from meta-analysis to assess whether the case manager should have a professional qualification, or if frequency of contact, case manager availability or conditionality (barriers due to conditions attached to service provision) influenced outcomes. However, the main theme from implementation studies concerned barriers where conditions were attached to services. Characteristics of Persons Experiencing Homelessness No conclusions could be drawn from meta-analysis other than a trend for greater reductions in homelessness for persons with high complexity of need (two or more support needs in addition to homelessness) as compared to those with medium complexity of need (one additional support need); effect sizes were SMD = -0.61 [-0.91, -0.31] versus -0.36 [-0.68, -0.05]; p = 0.3. The Broader Context of Delivery of Case Management Programmes Other major themes from the implementation studies included the importance of interagency partnership; provision for non-housing support and training needs of PEH (such as independent living skills), intensive community support following the move to new housing; emotional support and training needs of case managers; and an emphasis on housing safety, security and choice. Cost Effectiveness The 12 studies with cost data provided contrasting results and no clear conclusions. Some case management costs may be largely off-set by reductions in the use of other services. Cost estimates from three North American studies were $45-52 for each additional day housed. Authors' Conclusions Case management interventions improve housing outcomes for PEH with one or more additional support needs, with more intense interventions leading to greater benefits. Those with greater support needs may gain greater benefit. There is also evidence for improvements to capabilities and wellbeing. Current approaches do not appear to lead to mental health benefits. In terms of case management components, there is evidence in support of a team approach and in-person meetings and, from the implementation evidence, that conditions associated with service provision should be minimised. The approach within Housing First could explain the finding that overall benefits may be greater than for other types of case management. Four of its principles were identified as key themes within the implementation studies: No conditionality, offer choice, provide an individualised approach and support community building. Recommendations for further research include an expansion of the research base outside North America and further exploration of case management components and intervention cost-effectiveness.

Abstract
BACKGROUND To sufficiently house and support persons experiencing homelessness (PEH), deeper understandings of the cultural appropriateness and responsiveness of community resources and the service delivery system is essential. In the case of Metro Vancouver, Canada, the cultural appropriateness and responsiveness of Housing First as a service model for supporting PEH was explored. METHODS Local service providers and stakeholders (n = 52) participated in three full day service-mapping workshops to identify Housing First supports for older adults, youth, and women experiencing homelessness, as part of a municipal-wide participatory and action-oriented study. Data were analyzed using a structured framework thematic analysis approach and cultural safety and humility lenses. RESULTS We generated three key themes: (i) insufficient built environments create challenges across gender and age, (ii) cultural safety and humility concerns at the intersection of gender and age, and (iii) implications for a culturally-responsive Housing First implementation. CONCLUSIONS Findings informed the development of a Culturally-Responsive Planning resource to support housing, health, and social service providers who are implementing Housing First initiatives.

Public Health Interventions to Address Housing and Mental Health amongst Migrants from Culturally and Linguistically Diverse Backgrounds Living in High-Income Countries: A Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16946. [PMID: 36554827 PMCID: PMC9778908 DOI: 10.3390/ijerph192416946] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 12/09/2022] [Accepted: 12/11/2022] [Indexed: 06/17/2023]
Abstract
Migrants from culturally and linguistically diverse (CaLD) backgrounds experience factors that may increase health inequities related to a range of determinants of health including housing and mental health. However, the intersection between mental health and housing for migrants is poorly understood. A scoping review searched four academic databases for concepts related to cultural and linguistic diversity, housing conditions, and public health interventions to address homelessness. A total of 49 articles were included and seven key themes identified: housing provision; mental health intersections and interventions; complexity and needs beyond housing; substance use; service provider and policy issues; the role of cultural and linguistic diversity; and consumer experience. The intersection of ethnicity with other social determinants of health and housing was highlighted though there were limited interventions tailored for migrants. Studies generally pointed to the positive impacts of Housing First. Other sub-themes emerged: social connection and community; shame, stigma, and discrimination; health and support requirements; and employment, financial assistance, and income. Consumer choice was identified as vital, along with the need for systemic anti-racism work and interventions. To support secure housing for migrants and mitigate mental health impacts, closer attention is required towards migration factors along with broader, tailored services complementing housing provision.

Multivariable modelling of factors associated with criminal convictions among people experiencing homelessness and serious mental illness: a multi-year study. Sci Rep 2021; 11:16610. [PMID: 34400747 PMCID: PMC8368183 DOI: 10.1038/s41598-021-96186-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Accepted: 08/02/2021] [Indexed: 11/12/2022] Open
Abstract
People experiencing homelessness and serious mental illness exhibit high rates of criminal justice system involvement. Researchers have debated the causes of such involvement among people experiencing serious mental illness, including what services to prioritize. Some, for example, have emphasized mental illness while others have emphasized poverty. We examined factors associated with criminal convictions among people experiencing homelessness and serious mental illness recruited to the Vancouver At Home study. Participants were recruited between October 2009 and June 2011. Comprehensive administrative data were examined over the five-year period preceding study baseline to identify risk and protective factors associated with criminal convictions among participants (n = 425). Eight variables were independently associated with criminal convictions, some of which included drug dependence (RR = 1.53; P = 0.009), psychiatric hospitalization (RR = 1.44; P = 0.030), an irregular frequency of social assistance payments (compared to regular payments; 1.75; P < 0.001), and prior conviction (RR = 3.56; P < 0.001). Collectively, findings of the present study implicate poverty, social marginalization, crises involving mental illness, and the need for long-term recovery-oriented services that address these conditions to reduce criminal convictions among people experiencing homelessness and serious mental illness.

Abstract
Background Homelessness has emerged as a public health priority, with growing numbers of vulnerable populations despite advances in social welfare. In February 2020, the United Nations passed a historic resolution, identifying the need to adopt social-protection systems and ensure access to safe and affordable housing for all. The establishment of housing stability is a critical outcome that intersects with other social inequities. Prior research has shown that in comparison to the general population, people experiencing homelessness have higher rates of infectious diseases, chronic illnesses, and mental-health disorders, along with disproportionately poorer outcomes. Hence, there is an urgent need to identify effective interventions to improve the lives of people living with homelessness. Objectives The objective of this systematic review is to identify, appraise, and synthesise the best available evidence on the benefits and cost-effectiveness of interventions to improve the health and social outcomes of people experiencing homelessness. Search Methods In consultation with an information scientist, we searched nine bibliographic databases, including Medline, EMBASE, and Cochrane CENTRAL, from database inception to February 10, 2020 using keywords and MeSH terms. We conducted a focused grey literature search and consulted experts for additional studies. Selection Criteria Teams of two reviewers independently screened studies against our inclusion criteria. We included randomised control trials (RCTs) and quasi-experimental studies conducted among populations experiencing homelessness in high-income countries. Eligible interventions included permanent supportive housing (PSH), income assistance, standard case management (SCM), peer support, mental health interventions such as assertive community treatment (ACT), intensive case management (ICM), critical time intervention (CTI) and injectable antipsychotics, and substance-use interventions, including supervised consumption facilities (SCFs), managed alcohol programmes and opioid agonist therapy. Outcomes of interest were housing stability, mental health, quality of life, substance use, hospitalisations, employment and income. Data Collection and Analysis Teams of two reviewers extracted data in duplicate and independently. We assessed risk of bias using the Cochrane Risk of Bias tool. We performed our statistical analyses using RevMan 5.3. For dichotomous data, we used odds ratios and risk ratios with 95% confidence intervals. For continuous data, we used the mean difference (MD) with a 95% CI if the outcomes were measured in the same way between trials. We used the standardised mean difference with a 95% CI to combine trials that measured the same outcome but used different methods of measurement. Whenever possible, we pooled effect estimates using a random-effects model. Main Results The search resulted in 15,889 citations. We included 86 studies (128 citations) that examined the effectiveness and/or cost-effectiveness of interventions for people with lived experience of homelessness. Studies were conducted in the United States (73), Canada (8), United Kingdom (2), the Netherlands (2) and Australia (1). The studies were of low to moderate certainty, with several concerns regarding the risk of bias. PSH was found to have significant benefits on housing stability as compared to usual care. These benefits impacted both high- and moderate-needs populations with significant cimorbid mental illness and substance-use disorders. PSH may also reduce emergency department visits and days spent hospitalised. Most studies found no significant benefit of PSH on mental-health or substance-use outcomes. The effect on quality of life was also mixed and unclear. In one study, PSH resulted in lower odds of obtaining employment. The effect on income showed no significant differences. Income assistance appeared to have some benefits in improving housing stability, particularly in the form of rental subsidies. Although short-term improvement in depression and perceived stress levels were reported, no evidence of the long-term effect on mental health measures was found. No consistent impact on the outcomes of quality of life, substance use, hospitalisations, employment status, or earned income could be detected when compared with usual services. SCM interventions may have a small beneficial effect on housing stability, though results were mixed. Results for peer support interventions were also mixed, though no benefit was noted in housing stability specifically. Mental health interventions (ICM, ACT, CTI) appeared to reduce the number of days homeless and had varied effects on psychiatric symptoms, quality of life, and substance use over time. Cost analyses of PSH interventions reported mixed results. Seven studies showed that PSH interventions were associated with increased cost to payers and that the cost of the interventions were only partially offset by savings in medical- and social-services costs. Six studies revealed that PSH interventions saved the payers money. Two studies focused on the cost-effectiveness of income-assistance interventions. For each additional day housed, clients who received income assistance incurred additional costs of US$45 (95% CI, -$19, -$108) from the societal perspective. In addition, the benefits gained from temporary financial assistance were found to outweigh the costs, with a net savings of US$20,548. The economic implications of case management interventions (SCM, ICM, ACT, CTI) was highly uncertain. SCM clients were found to incur higher costs than those receiving the usual care. For ICM, all included studies suggested that the intervention may be cost-offset or cost-effective. Regarding ACT, included studies consistently revealed that ACT saved payers money and improved health outcomes than usual care. Despite having comparable costs (US$52,574 vs. US$51,749), CTI led to greater nonhomeless nights (508 vs. 450 nights) compared to usual services. Authors' Conclusions PSH interventions improved housing stability for people living with homelessness. High-intensity case management and income-assistance interventions may also benefit housing stability. The majority of included interventions inconsistently detected benefits for mental health, quality of life, substance use, employment and income. These results have important implications for public health, social policy, and community programme implementation. The COVID-19 pandemic has highlighted the urgent need to tackle systemic inequality and address social determinants of health. Our review provides timely evidence on PSH, income assistance, and mental health interventions as a means of improving housing stability. PSH has major cost and policy implications and this approach could play a key role in ending homelessness. Evidence-based reviews like this one can guide practice and outcome research and contribute to advancing international networks committed to solving homelessness.

Homelessness Is Socially Created: Cluster Analysis of Social Determinants of Homelessness (SODH) in North West England in 2020. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18063066. [PMID: 33809704 PMCID: PMC8002255 DOI: 10.3390/ijerph18063066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/11/2021] [Accepted: 03/12/2021] [Indexed: 11/18/2022]
Abstract
Poverty creates social conditions that increase the likelihood of homelessness. These include exposure to traumatic life experiences; social disadvantages such as poor educational experiences; being raised in a broken family, care homes or foster care; physical, emotional, and sexual abuse; and neglect at an early age. These conditions reduce people’s ability to negotiate through life challenges. This cross-sectional study documents the clustering and frequency of adverse social conditions among 152 homeless people from four cities in North West England between January and August 2020. Two-step cluster analysis showed that having parents with a criminal record, care history, and child neglect/abuse history was predictive of homelessness. The cluster of indicator variables among homeless people included sexual abuse (χ2 (N = 152) = 220.684, p < 0.001, Cramer’s V = 0.7), inappropriate sexual behaviour (χ2 (N = 152) = 207.737, p < 0.001, Cramer’s V = 0.7), emotional neglect (χ2 (N = 152) = 181.671, p < 0.001, Cramer’s V = 0.7), physical abuse by step-parent (χ2 (N = 152) = 195.882, p < 0.001, Cramer’s V = 0.8), and physical neglect (χ2 (N = 152) = 205.632, p < 0.001, Cramer’s V = 0.8). Poverty and homelessness are intertwined because of the high prevalence of poverty among the homeless. Poverty sets up a chain of interactions between social conditions that increase the likelihood of unfavourable outcomes: homelessness is at the end of the interaction chain. Interventions supporting families to rise out of poverty may also reduce entry into homelessness.

Abstract
BACKGROUND Researchers have pointed out the paucity of research investigating long-term consequences of experiencing homelessness in childhood or youth. Limited research has indicated that the experience of homelessness in childhood or youth is associated with adverse adjustment-related consequences in adulthood. Housing First (HF) has acknowledged effectiveness in improving housing outcomes among adults experiencing homelessness and living with serious mental illness, although some HF clients struggle with maintaining housing. The current study was conducted to examine whether the experience of homelessness in childhood or youth increases the odds of poorer housing stability following entry into high-fidelity HF among adults experiencing serious mental illness and who were formerly homeless. METHODS Data were drawn from the active intervention arms of a HF randomized controlled trial in Metro Vancouver, Canada. Participants (n = 297) were referred to the study from service agencies serving adults experiencing homelessness and mental illness between October 2009 and June 2011. The Residential Time-Line Follow-Back Inventory was used to measure housing stability. Least absolute shrinkage and selection operator was used to estimate the association between first experiencing homelessness in childhood or youth and later housing stability as an adult in HF. RESULTS Analyses indicated that homelessness in childhood or youth was negatively associated with experiencing housing stability as an adult in HF (aOR = 0.53; 95% CI = 0.31-0.90). CONCLUSIONS Further supports are needed within HF to increase housing stability among adult clients who have experienced homelessness in childhood or youth. Asking clients about the age they first experienced homelessness may be of clinical utility upon enrollment in HF and may help identify support needs related to developmental experiences. Results further emphasize the importance of intervening earlier in life in childhood and youth before experiencing homelessness or before it becomes chronic. Findings also contribute to a limited knowledge base regarding the adverse long-term consequences of childhood and youth homelessness.

Abstract
OBJECTIVE To assess impact of employment on recovery in a sample of adults from Vancouver At Home (VAH) study, who were homeless and were diagnosed with severe mental disorders. METHODS The VAH included two randomized controlled trials investigating the effect of housing first with support intervention in vulnerable population. Employment was assessed at baseline and during the follow-up using Demographics, Housing, Vocational, and Service Use History (DSHH), and Vocational Timeline Follow-Back (VTLFB) self-report questionnaires, respectively. Recovery was examined using Recovery Assessment Scale (RAS) at baseline and at 24-month follow-up visit. Multivariable regression models were built to examine: (1) the effect of current employment at baseline on RAS score at baseline, and RAS score at 24-month follow-up visit; and (2) and to examine the cumulative effect of recent employment over 8 follow-up visits on RAS score at 24-month visit. Cumulative effect of employment over the follow-up visits was weighted by recency using a pre-specified weighting function. RESULTS Employment at baseline was associated with an increase in recovery score at baseline [8.06 (95% CI 1.21, 14.91); p = 0.02], but not with recovery score at 24-month follow-up visit [3.78 (-4.67, 12.24); p = 0.37]. Weighted cumulative effect of employment over 8 follow-up visits was associated with increase in RAS score at 24-month follow-up visit [8.33 (1.68, 14.99) p = 0.01]. CONCLUSION Employment is associated with an increase in recovery. Our result suggests a dual effect of employment on recovery, an immediate effect through current employment, and a long-term effect of cumulative employment.

Abstract
Across Europe, as governments turn to housing-led strategies in attempts to reverse rising rates of homelessness, increasing numbers of Housing First (HF) programs are being implemented. As HF programs become more widespread, it is important to understand how service users experience them compared to the more prevalent traditional treatment-first approach to addressing long-term homelessness. Although there is a large body of research on service users' experiences of Housing First compared to treatment-first in North American contexts, comparatively less is known about how these two categories of homeless services are experienced in the European context. In a correlational and cross-sectional study, part of a larger examination of homelessness in Europe, participants (n = 520) engaged with either HF (n = 245) or traditional services (TS; n = 275) programs in seven countries completed measures of their experiences of services (consumer choice, housing quality, and service satisfaction) and recovery (time in independent housing, psychiatric symptoms, and community integration). Across the seven countries, participants engaged with HF programs reported experiencing more consumer choice, better perceived housing quality, and more satisfaction with services than participants engaged in TS programs. Participants in HF programs also reported a greater proportion of time in independent accommodation, fewer psychiatric symptoms, and more community integration. Varying patterns of association between experiences of services and recovery outcomes were observed. Findings indicate HF consistently predicts greater recovery than TS across diverse sociopolitical and economic contexts. Implications of findings for configurations of homeless services and homeless services policy are discussed.

Abstract
We are sadly experiencing unprecedented levels of overdose mortalities attributed to the increased availability of synthetic opioids in illegal markets. While the majority of attention in North America has focused on preventing drug overdose cases through the distribution and administration of naloxone, in addition to stricter regulations of opioid prescriptions and greater law enforcement in illegal markets, little attention has been given to other alternative models and treatments for people who use drugs that are tailored specifically to the health care needs of this marginalized population. Through this analysis, the implications of task-shifting in health care via the distribution of naloxone for an already marginalized population are discussed. Alternatively, the role of pioneering harm-reduction programs - such as supervised injection/consumption sites, a variety of opioids maintenance therapies, and social-structural interventions - are highlighted as crucial interventions in the current ongoing opioid crisis. Moreover, people with lived experiences of illegal drug use are discussed as having a pivotal role but being ultimately overshadowed by public health partners.

Abstract
BACKGROUND Even low levels of substance misuse by people with a severe mental illness can have detrimental effects. OBJECTIVES To assess the effects of psychosocial interventions for reduction in substance use in people with a serious mental illness compared with standard care. SEARCH METHODS The Information Specialist of the Cochrane Schizophrenia Group (CSG) searched the CSG Trials Register (2 May 2018), which is based on regular searches of major medical and scientific databases. SELECTION CRITERIA We included all randomised controlled trials (RCTs) comparing psychosocial interventions for substance misuse with standard care in people with serious mental illness. DATA COLLECTION AND ANALYSIS Review authors independently selected studies, extracted data and appraised study quality. For binary outcomes, we calculated standard estimates of risk ratio (RR) and their 95% confidence intervals (CIs) on an intention-to-treat basis. For continuous outcomes, we calculated the mean difference (MD) between groups. Where meta-analyses were possible, we pooled data using a random-effects model. Using the GRADE approach, we identified seven patient-centred outcomes and assessed the quality of evidence for these within each comparison. MAIN RESULTS Our review now includes 41 trials with a total of 4024 participants. We have identified nine comparisons within the included trials and present a summary of our main findings for seven of these below. We were unable to summarise many findings due to skewed data or because trials did not measure the outcome of interest. In general, evidence was rated as low- or very-low quality due to high or unclear risks of bias because of poor trial methods, or inadequately reported methods, and imprecision due to small sample sizes, low event rates and wide confidence intervals. 1. Integrated models of care versus standard care (36 months) No clear differences were found between treatment groups for loss to treatment (RR 1.09, 95% CI 0.82 to 1.45; participants = 603; studies = 3; low-quality evidence), death (RR 1.18, 95% CI 0.39 to 3.57; participants = 421; studies = 2; low-quality evidence), alcohol use (RR 1.15, 95% CI 0.84 to 1.56; participants = 143; studies = 1; low-quality evidence), substance use (drug) (RR 0.89, 95% CI 0.63 to 1.25; participants = 85; studies = 1; low-quality evidence), global assessment of functioning (GAF) scores (MD 0.40, 95% CI -2.47 to 3.27; participants = 170; studies = 1; low-quality evidence), or general life satisfaction (QOLI) scores (MD 0.10, 95% CI -0.18 to 0.38; participants = 373; studies = 2; moderate-quality evidence). 2. Non-integrated models of care versus standard care There was no clear difference between treatment groups for numbers lost to treatment at 12 months (RR 1.21, 95% CI 0.73 to 1.99; participants = 134; studies = 3; very low-quality evidence). 3. Cognitive behavioural therapy (CBT) versus standard care There was no clear difference between treatment groups for numbers lost to treatment at three months (RR 1.12, 95% CI 0.44 to 2.86; participants = 152; studies = 2; low-quality evidence), cannabis use at six months (RR 1.30, 95% CI 0.79 to 2.15; participants = 47; studies = 1; very low-quality evidence) or mental state insight (IS) scores by three months (MD 0.52, 95% CI -0.78 to 1.82; participants = 105; studies = 1; low-quality evidence). 4. Contingency management versus standard care We found no clear differences between treatment groups for numbers lost to treatment at three months (RR 1.55, 95% CI 1.13 to 2.11; participants = 255; studies = 2; moderate-quality evidence), number of stimulant positive urine tests at six months (RR 0.83, 95% CI 0.65 to 1.06; participants = 176; studies = 1) or hospitalisations (RR 0.21, 95% CI 0.05 to 0.93; participants = 176; studies = 1); both low-quality evidence. 5. Motivational interviewing (MI) versus standard care We found no clear differences between treatment groups for numbers lost to treatment at six months (RR 1.71, 95% CI 0.63 to 4.64; participants = 62; studies = 1). A clear difference, favouring MI, was observed for abstaining from alcohol (RR 0.36, 95% CI 0.17 to 0.75; participants = 28; studies = 1) but not other substances (MD -0.07, 95% CI -0.56 to 0.42; participants = 89; studies = 1), and no differences were observed in mental state general severity (SCL-90-R) scores (MD -0.19, 95% CI -0.59 to 0.21; participants = 30; studies = 1). All very low-quality evidence. 6. Skills training versus standard care At 12 months, there were no clear differences between treatment groups for numbers lost to treatment (RR 1.42, 95% CI 0.20 to 10.10; participants = 122; studies = 3) or death (RR 0.15, 95% CI 0.02 to 1.42; participants = 121; studies = 1). Very low-quality, and low-quality evidence, respectively. 7. CBT + MI versus standard care At 12 months, there was no clear difference between treatment groups for numbers lost to treatment (RR 0.99, 95% CI 0.62 to 1.59; participants = 327; studies = 1; low-quality evidence), number of deaths (RR 0.60, 95% CI 0.20 to 1.76; participants = 603; studies = 4; low-quality evidence), relapse (RR 0.50, 95% CI 0.24 to 1.04; participants = 36; studies = 1; very low-quality evidence), or GAF scores (MD 1.24, 95% CI -1.86 to 4.34; participants = 445; studies = 4; very low-quality evidence). There was also no clear difference in reduction of drug use by six months (MD 0.19, 95% CI -0.22 to 0.60; participants = 119; studies = 1; low-quality evidence). AUTHORS' CONCLUSIONS We included 41 RCTs but were unable to use much data for analyses. There is currently no high-quality evidence to support any one psychosocial treatment over standard care for important outcomes such as remaining in treatment, reduction in substance use or improving mental or global state in people with serious mental illnesses and substance misuse. Furthermore, methodological difficulties exist which hinder pooling and interpreting results. Further high-quality trials are required which address these concerns and improve the evidence in this important area.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E4620.

Abstract
Background: Homelessness is rising in the United Kingdom, despite investment in measures to eradicate it made by the government and charity organisations. Aim: The aim is to examine the stories of homeless people in order to document their perceptions of their social status, the reasons that led to their homelessness, and propose a conceptual explanation. Method: We conducted 26 semi-structured interviews in three centres for homeless people in Cheshire, North West of England. Results: Three categories-education, employment, and health-emerged from the data and provided a theoretical explanation for the reasons that led to their homelessness. These are vital not only for the successful negotiation of one's way out of homelessness, but also for achieving other social goods, including social connections, social mobility, and engaging in positive social relationships. Conclusion: Participants catalogued the adverse childhood experiences, which they believe limited their capacity to meaningfully engage with the social institution for social goods, such as education, social services, and institutions of employment. Since not all people who have misfortunes of poor education, poor health, and loss of job end up being homeless, we contend that a combination of these with multiple adverse childhood experiences may have weakened their resilience to traumatic life changes, such as loss of job and poor health.

Abstract
BACKGROUND Indigenous people are over represented among homeless populations worldwide and the prevalence of Indigenous homelessness appears to be increasing in Canadian cities. Violence against Indigenous women in Canada has been widely publicized but has not informed the planning of housing interventions. Despite historical policies leading to disenfranchisement of Indigenous rights in gender-specific ways, little is known about contemporary differences in need between homeless Indigenous men and women. This study investigated mental health, substance use and service use among Indigenous people who met criteria for homelessness and mental illness, and hypothesized that, compared to men, women would have significantly higher rates of trauma, suicidality, substance dependence, and experiences of violence. METHODS This study was conducted using baseline (pre-randomization) data from a multi-site trial. Inclusion in the current analyses was restricted to participants who self-reported Indigenous ethnicity, and combined eligible participants from Vancouver, BC and Winnipeg, MB. Logistic regression analyses were used to model the independent associations between gender and outcome variables. RESULTS In multivariable regression models among Indigenous participants (n = 439), female gender was predictive of meeting criteria for PTSD, multiple mental disorders, current high suicidality and current substance dependence. Female gender was also significantly associated with reported physical (AOR: 1.52, 95% CI = 1.10-2.23) and sexual (AOR: 6.31, 95% CI = 2.78-14.31) violence. CONCLUSIONS Our analyses of Indigenous men and women who are homeless illustrate the distinct legacy of colonization on the experiences of Indigenous women. Our findings are consistent with the widely documented violence against Indigenous women in Canada. Housing policies and services are urgently needed that take Indigenous historical contexts, trauma and gender into account. TRIAL REGISTRATION This trial has been registered with the International Standard Randomized Control Trial Number Register and assigned ISRCTN42520374 ; ISRCTN57595077 ; ISRCTN66721740 .

Abstract
OBJECTIVES To understand the experience of Metro Vancouver's Homelessness Partnering Strategy-funded Housing First program and how it is functioning from the perspective of a representative sample of providers and clients who deliver and receive HF services. METHODS Thirty-four clients and providers who currently or formerly delivered HF in Metro Vancouver participated in one-on-one interviews (n = 26) or focus groups (n = 8) between March and April 2017 and data were thematically analyzed. RESULTS Strengths of the HF program included: the ability to transition persons from the street into housing with individualized service supports and, in certain cases, with 12-month rent subsidies, household goods, and connection to community resources. Identified program weaknesses were: eligibility criteria, limited rent subsidy funds, limited provider capacity, and workload burden. Suggested opportunities to improve HF were: streamlining federal and provincial reporting and rent subsidy systems and building friendly landlord networks. Potential threats to HF described were: limited affordable housing, stigma and discrimination toward clients, inadequate income assistance, and limited opportunity for cross-sector collaboration. CONCLUSIONS The delivery of HF in regions that have limited affordable housing presents unique challenges. Recommendations are provided to improve HF practice and policy in these contexts.

Abstract
OBJECTIVES Indigenous people in Canada are not only over-represented among the homeless population but their pathways to homelessness may differ from those of non-Indigenous people. This study investigated the history and current status of Indigenous and non-Indigenous people experiencing homelessness and mental illness. We hypothesised that compared with non-Indigenous people, those who are Indigenous would demonstrate histories of displacement earlier in life, higher rates of trauma and self-medication with alcohol and other substances. DESIGN AND SETTING Retrospective data were collected from a sample recruited through referral from diverse social and health agencies in Winnipeg and Vancouver. PARTICIPANTS Eligibility included being 19 years or older, current mental disorder and homelessness. MEASURES Data were collected via interviews, using questionnaires, on sociodemographics (eg, age, ethnicity, education), mental illness, substance use, physical health, service use and quality of life. Univariate and multivariable models were used to model the association between Indigenous ethnicity and dependent variables. RESULTS A total of 1010 people met the inclusion criteria, of whom 439 self-identified as Indigenous. In adjusted models, Indigenous ethnicity was independently associated with being homeless at a younger age, having a lifetime duration of homelessness longer than 3 years, post-traumatic stress disorder, less severe mental disorder, alcohol dependence, more severe substance use in the past month and infectious disease. Indigenous participants were also nearly twice as likely as others (47% vs 25%) to have children younger than 18 years. CONCLUSIONS Among Canadians who are homeless and mentally ill, those who are Indigenous have distinct histories and current needs that are consistent with the legacy of colonisation. Responses to Indigenous homelessness must be developed within the context of reconciliation between Indigenous and non-Indigenous Canadians, addressing trauma, substance use and family separations.

Abstract
OBJECTIVE To examine whether timely outpatient follow-up after hospital discharge reduces the risk of subsequent rehospitalization among people experiencing homelessness and mental illness. DATA SOURCES Comprehensive linked administrative data including hospital admissions, laboratory services, and community medical services. STUDY DESIGN Participants were recruited to the Vancouver At Home study based on a-priori criteria for homelessness and mental illness (n = 497). Logistic regression analysis was used to assess the relationship between outpatient care within 7 days postdischarge and subsequent rehospitalization over a 1-year period. DATA EXTRACTION Data were extracted for a consenting subsample of participants (n = 433) spanning 5 years prior to study enrollment. PRINCIPAL FINDINGS More than half of the eligible sample (53 percent; n = 128) were rehospitalized within 1 year following an index hospital discharge. Neither outpatient medical services nor laboratory services within 7 days following discharge were associated with a significantly reduced likelihood of rehospitalization within 2 months (AOR = 1.17 [CI = 0.94, 1.46]), 6 months (AOR = 1.00 [CI = 0.82, 1.23]) or 12 months (AOR = 1.24 [CI = 1.02, 1.52]). CONCLUSIONS In contrast to evidence from nonhomeless samples, we found no association between timely outpatient follow-up and the likelihood of rehospitalization in our homeless, mentally ill cohort. Our findings indicate a need to address housing as an essential component of discharge planning alongside outpatient care.

Abstract
Adherence to antipsychotic medication is a significant challenge among homeless patients. No experimental trials have investigated the impact of Housing First on adherence among patients with schizophrenia. We investigated whether Housing First in congregate and scattered-site configurations resulted in superior adherence compared to usual care. Adult participants (n = 165) met criteria for homelessness, schizophrenia, and initiation of antipsychotic pharmacotherapy prior to recruitment to an unblinded, 3-arm randomized controlled trial in Vancouver, Canada. Randomization arms were: congregate Housing First (CHF) with on-site supports (including physician and pharmacy services); scattered-site Housing First (SHF) with Assertive Community Treatment; or treatment as usual (TAU) consisting of existing services. Participants were followed for an average of 2.6 years. Adherence to antipsychotic medication was measured using the medication possession ratio (MPR), and 1-way ANOVA was used to compare outcomes between the 3 conditions. Data were drawn from comprehensive pharmacy records. Prior to randomization, mean MPR among participants was very low (0.44–0.48). Mean MPR in the follow-up period was significantly different between study arms (P < .001) and approached the guideline threshold of 0.80 in SHF. Compared to TAU, antipsychotic adherence was significantly higher in SHF but not in CHF. The results demonstrate that further implementation of SHF is indicated among homeless people with schizophrenia, and that urgent action is needed to address very low levels of antipsychotic adherence in this population (trial registration: ISRCTN57595077).

Abstract
BACKGROUND Homelessness is associated with enormous health inequalities, including shorter life expectancy, higher morbidity and greater usage of acute hospital services. Viewed through the lens of social determinants, homelessness is a key driver of poor health, but homelessness itself results from accumulated adverse social and economic conditions. Indeed, in people who are homeless, the social determinants of homelessness and health inequities are often intertwined, and long term homelessness further exacerbates poor health. Aggregated health service data can mask this, and case histories thus provide important insights. METHODS This paper presents three case histories of homeless patients seen at an inner city public hospital in Perth, Western Australia. The case histories draw on several data sources: hospital data, information collected from rough sleepers and clinical observations. Estimates of the cost to the health system of the observed hospital usage by the three patients are included. FINDINGS The case histories illustrate the interplay of social determinants of health in homelessness that help explain the high level of hospital usage by rough sleepers. The cumulative healthcare costs for the three individuals over a 33 months period were substantial. Hospital attendance plummeted even in the short term when housing needs were addressed. CONCLUSIONS Treating homelessness as a combined health and social issue is critical to improving the abysmal health outcomes of people experiencing homelessness. In addition, the enormous economic costs of hospital care for people who are homeless can be reduced when housing and other social determinants are taken into account.

Abstract
BACKGROUND Methadone maintenance treatment (MMT) has important protective effects related to reduced illicit opioid use, infectious disease transmission, and overdose mortality. Adherence to MMT has not been examined among homeless people. We measured MMT adherence and reported relevant characteristics among homeless adults experiencing mental illness in Vancouver, British Columbia, Canada. MATERIAL AND METHODS Homeless adults living with mental illness who had received MMT prior to the baseline interview of the Vancouver At Home study (n = 78) were included in analyses. The medication possession ratio (MPR) was used to estimate MMT adherence from retrospective administrative pharmacy and public health insurance data collected across 15 years. Independent sample t tests and one-way ANOVA were used to test for significant differences in MMT MPR by participant characteristics. RESULTS Mean MMT MPR was 0.47. A large proportion of participants reported blood-borne infectious disease, three or more chronic physical health conditions, and substance use. Being single and never married was associated with significantly lower MMT MPR (0.40 vs. 0.55, p = 0.036), while living with schizophrenia, bipolar disorder, or a mood disorder with psychotic features was associated with significantly higher MMT MPR (0.54 vs. 0.37, p = 0.022). Daily drug use (excluding alcohol) was associated with significantly lower MMT MPR (0.39 vs. 0.54, p = 0.051). CONCLUSIONS The level of adherence to MMT was very low among homeless adults experiencing mental illness. Efforts are needed to improve adherence to MMT as a means of reducing illicit substance use, preventing overdose deaths, and attenuating infectious disease transmission.

Abstract
BACKGROUND It is increasingly acknowledged that homelessness is a more complex social and public health phenomenon than the absence of a place to live. This view signifies a paradigm shift, from the definition of homelessness in terms of the absence of permanent accommodation, with its focus on pathways out of homelessness through the acquisition and maintenance of permanent housing, to understanding the social context of homelessness and social interventions to prevent it. However, despite evidence of the association between homelessness and social factors, there is very little research that examines the wider social context within which homelessness occurs from the perspective of homeless people themselves. This study aims to examine the stories of homeless people to gain understanding of the social conditions under which homelessness occurs, in order to propose a theoretical explanation for it. METHOD Twenty-six semi-structured interviews were conducted with homeless people in three centres for homeless people in Cheshire North West of England. RESULTS The analysis revealed that becoming homeless is a process characterised by a progressive waning of resilience capacity to cope with life challenges created by series of adverse incidents in one's life. The data show that final stage in the process of becoming homeless is complete collapse of relationships with those close to them. Most prominent pattern of behaviours participants often describe as main causes of breakdown of their relationships are: 1. engaging in maladaptive behavioural lifestyle including taking drugs and/or excessive alcohol drinking 2. Being in trouble with people in authorities. CONCLUSION Homeless people describe the immediate behavioural causes of homelessness, however, the analysis revealed the social and economic conditions within which homelessness occurred. The participants' descriptions of the social conditions in which were raised and their references to maladaptive behaviours which led to them becoming homeless, led us to conclude that they believe that their social condition affected their life chances: that these conditions were responsible for their low quality of social connections, poor educational attainment, insecure employment and other reduced life opportunities available to them.

Abstract
BACKGROUND Housing First is an evidence-based practice intended to serve chronically homeless individuals with co-occurring serious mental illness and substance use disorders. Despite housing active substance users, harm reduction is an often-overlooked element during the Housing First implementation process in real-world settings. In this paper, we explore the representation of the Housing First model within the open-access scholarly literature as a potential contributing factor for this oversight. METHODS We conducted a rapid review of the US and Canadian open-access Housing First literature. We followed a document analysis approach, to form an interpretation of the articles' content related to our primary research questions. RESULTS A total of 55 articles on Housing First were included in the final analysis. Only 21 of these articles (38.1%) included explicit mention of harm reduction. Of the 34 articles that did not discuss harm reduction, 22 provided a description of the Housing First model indicating it does not require abstinence from substance use; however, descriptions did not all clearly indicate abstinence was not required beyond program entry. Additional Housing First descriptions focused on the low-barrier entry criteria and/or the intervention's client-centeredness. CONCLUSIONS Our review demonstrated a lack of both explicit mention and informed discussion of harm reduction in the Housing First literature, which is likely contributing to the Housing First research-practice gap to some degree. Future Housing First literature should accurately explain the role of harm reduction when discussing it in the context of Housing First programming, and public agencies promoting Housing First uptake should provide resources for proper implementation and monitor program fidelity to prevent model drift.

Abstract
Background Homeless individuals with mental illness are challenging to recruit and retain in longitudinal research studies. The present study uses information from the Vancouver site of a Canadian multi-city longitudinal randomized controlled trial on housing first interventions for homeless individuals. We were able to recruit 500 participants and retain large number of homeless individuals with mental illness; 92% of the participants completed the 6-month follow up interview, 84% the 24-month follow up, while 80% completed all follow-up visits of the study. Purpose In this article, we describe the strategies and practices that we considered as critical for successful recruitment and retention or participants in the study. Methods We discuss issues pertaining to research staff hiring and training, involvement of peers, relationship building with research participants, and the use of technology and social media, and managing challenging situations in the context of recruitment and retention of marginalized individuals. Conclusions Recruitment and retention of homeless participant with mental illness in longitudinal studies is feasible. It requires flexible, unconventional and culturally competent strategies. Longitudinal research projects with vulnerable and hidden populations may benefit from extensive outreach work and collaborative approaches that are based on attitudes of mutual respect, contextual knowledge and trust.

Abstract
Mental illness and substance use are overrepresented within urban homeless populations. This paper compared substance use patterns between homeless individuals diagnosed with schizophrenia spectrum (SS) and bipolar disorders (BD) using the Mini-International Neuropsychiatric Interview. From a sample of 497 subjects drawn from Vancouver, Canada who participated in the At Home/Chez Soi study, 146 and 94 homeless individuals were identified as BD and SS, respectively. In the previous 12 months, a greater proportion of BD homeless reported greater use of cocaine (χ = 20.0, p = 0.000), amphetamines (χ = 13,8, p = 0.000), opiates (χ = 24.6, p = 0.000), hallucinogens (χ = 11.7, p = 0.000), cannabinoids (χ = 5.05, p = 0.034), and tranquilizers (χ = 7.95, p = 0.004) compared to SS. Cocaine and opiates were significantly associated with BD homeless (χ = 39.06, df = 2, p < 0.000). The present study illustrates the relationship between substance use and BD in a vulnerable urban population of homeless, affected by adverse psychosocial factors and severe psychiatric conditions.

Abstract
OBJECTIVE No previous experimental trials have investigated Housing First (HF) in both scattered site (SHF) and congregate (CHF) formats. We hypothesized that CHF and SHF would be associated with a greater percentage of time stably housed as well as superior health and psychosocial outcomes over 24 months compared to treatment as usual (TAU). METHODS Inclusion criteria were homelessness, mental illness, and high need for support. Participants were randomised to SHF, CHF, or TAU. SHF consisted of market rental apartments with support provided by Assertive Community Treatment (ACT). CHF consisted of a single building with supports equivalent to ACT. TAU included existing services and supports. RESULTS Of 800 people screened, 297 were randomly assigned to CHF (107), SHF (90), or TAU (100). The percentage of time in stable housing over 24 months was 26.3% in TAU (reference; 95% confidence interval (CI) = 20.5, 32.0), compared to 74.3% in CHF (95% CI = 69.3, 79.3, p<0.001) and 74.5% in SHF (95% CI = 69.2, 79.7, p<0.001). Secondary outcomes favoured CHF but not SHF compared to TAU. CONCLUSION HF in scattered and congregate formats is capable of achieving housing stability among people experiencing major mental illness and chronic homelessness. Only CHF was associated with improvement on select secondary outcomes. REGISTRATION Current Controlled Trials: ISRCTN57595077.

Abstract
BACKGROUND Intensive Case Management (ICM) is a community-based package of care aiming to provide long-term care for severely mentally ill people who do not require immediate admission. Intensive Case Management evolved from two original community models of care, Assertive Community Treatment (ACT) and Case Management (CM), where ICM emphasises the importance of small caseload (fewer than 20) and high-intensity input. OBJECTIVES To assess the effects of ICM as a means of caring for severely mentally ill people in the community in comparison with non-ICM (caseload greater than 20) and with standard community care. We did not distinguish between models of ICM. In addition, to assess whether the effect of ICM on hospitalisation (mean number of days per month in hospital) is influenced by the intervention's fidelity to the ACT model and by the rate of hospital use in the setting where the trial was conducted (baseline level of hospital use). SEARCH METHODS We searched the Cochrane Schizophrenia Group's Trials Register (last update search 10 April 2015). SELECTION CRITERIA All relevant randomised clinical trials focusing on people with severe mental illness, aged 18 to 65 years and treated in the community care setting, where ICM is compared to non-ICM or standard care. DATA COLLECTION AND ANALYSIS At least two review authors independently selected trials, assessed quality, and extracted data. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated mean difference (MD) between groups and its 95% CI. We employed a random-effects model for analyses.We performed a random-effects meta-regression analysis to examine the association of the intervention's fidelity to the ACT model and the rate of hospital use in the setting where the trial was conducted with the treatment effect. We assessed overall quality for clinically important outcomes using the GRADE approach and investigated possible risk of bias within included trials. MAIN RESULTS The 2016 update included two more studies (n = 196) and more publications with additional data for four already included studies. The updated review therefore includes 7524 participants from 40 randomised controlled trials (RCTs). We found data relevant to two comparisons: ICM versus standard care, and ICM versus non-ICM. The majority of studies had a high risk of selective reporting. No studies provided data for relapse or important improvement in mental state.1. ICM versus standard careWhen ICM was compared with standard care for the outcome service use, ICM slightly reduced the number of days in hospital per month (n = 3595, 24 RCTs, MD -0.86, 95% CI -1.37 to -0.34,low-quality evidence). Similarly, for the outcome global state, ICM reduced the number of people leaving the trial early (n = 1798, 13 RCTs, RR 0.68, 95% CI 0.58 to 0.79, low-quality evidence). For the outcome adverse events, the evidence showed that ICM may make little or no difference in reducing death by suicide (n = 1456, 9 RCTs, RR 0.68, 95% CI 0.31 to 1.51, low-quality evidence). In addition, for the outcome social functioning, there was uncertainty about the effect of ICM on unemployment due to very low-quality evidence (n = 1129, 4 RCTs, RR 0.70, 95% CI 0.49 to 1.0, very low-quality evidence).2. ICM versus non-ICMWhen ICM was compared with non-ICM for the outcome service use, there was moderate-quality evidence that ICM probably makes little or no difference in the average number of days in hospital per month (n = 2220, 21 RCTs, MD -0.08, 95% CI -0.37 to 0.21, moderate-quality evidence) or in the average number of admissions (n = 678, 1 RCT, MD -0.18, 95% CI -0.41 to 0.05, moderate-quality evidence) compared to non-ICM. Similarly, the results showed that ICM may reduce the number of participants leaving the intervention early (n = 1970, 7 RCTs, RR 0.70, 95% CI 0.52 to 0.95,low-quality evidence) and that ICM may make little or no difference in reducing death by suicide (n = 1152, 3 RCTs, RR 0.88, 95% CI 0.27 to 2.84, low-quality evidence). Finally, for the outcome social functioning, there was uncertainty about the effect of ICM on unemployment as compared to non-ICM (n = 73, 1 RCT, RR 1.46, 95% CI 0.45 to 4.74, very low-quality evidence).3. Fidelity to ACTWithin the meta-regression we found that i.) the more ICM is adherent to the ACT model, the better it is at decreasing time in hospital ('organisation fidelity' variable coefficient -0.36, 95% CI -0.66 to -0.07); and ii.) the higher the baseline hospital use in the population, the better ICM is at decreasing time in hospital ('baseline hospital use' variable coefficient -0.20, 95% CI -0.32 to -0.10). Combining both these variables within the model, 'organisation fidelity' is no longer significant, but the 'baseline hospital use' result still significantly influences time in hospital (regression coefficient -0.18, 95% CI -0.29 to -0.07, P = 0.0027). AUTHORS' CONCLUSIONS Based on very low- to moderate-quality evidence, ICM is effective in ameliorating many outcomes relevant to people with severe mental illness. Compared to standard care, ICM may reduce hospitalisation and increase retention in care. It also globally improved social functioning, although ICM's effect on mental state and quality of life remains unclear. Intensive Case Management is at least valuable to people with severe mental illnesses in the subgroup of those with a high level of hospitalisation (about four days per month in past two years). Intensive Case Management models with high fidelity to the original team organisation of ACT model were more effective at reducing time in hospital.However, it is unclear what overall gain ICM provides on top of a less formal non-ICM approach.We do not think that more trials comparing current ICM with standard care or non-ICM are justified, however we currently know of no review comparing non-ICM with standard care, and this should be undertaken.

Abstract
PURPOSE The purpose of this study was to investigate the level of adherence to antipsychotic prescription medication in a well-defined homeless cohort over a 15-year period. We hypothesized that adherence would be well below the recommended threshold for clinical effectiveness (80 %), and that it would be strongly associated with modifiable risk factors in the social environment in which homeless people live. METHOD Linked baseline data (including comprehensive population-level administrative prescription records) were examined in a subpopulation of participants from two pragmatic-randomized trials that investigated Housing First for homeless and mentally ill adults. Adherence to antipsychotic medication was operationalized using the medication possession ratio. Multivariable logistic regression was used to estimate effect sizes between socio-demographic, homelessness-related and illness factors, and medication possession ratio. RESULTS Among the 290 participants who met inclusion criteria for the current analysis, adherence to antipsychotic prescription was significantly associated with: history of psychiatric hospitalization; receipt of primary medical services; long-acting injectable antipsychotic formulations; and duration of homelessness. Mean medication possession ratio in the pre-randomization period was 0.41. Socio-demographic characteristics previously correlated with antipsychotic non-adherence were not significantly related to medication possession ratio. CONCLUSIONS This is the first study to quantify the very low level of adherence to antipsychotic medication among homeless people over an extended observation period of 15 years. Each of the four factors found to be significantly associated with adherence presents opportunities for intervention. Strategies to end homelessness for this population may represent the greatest opportunity to improve adherence to antipsychotic medication.

Abstract
Housing quality (HQ) is associated with mental health, and may mediate outcomes in housing interventions. However, studies of housing interventions rarely report HQ. The purpose of this study was to describe HQ in a multi-site randomized controlled trial of Housing First (HF) in five Canadian cities and to examine possible differences by treatment group (HF recipients and treatment-as-usual (TAU) participants who were able to find housing through other programs or on their own). We also examined the association between HQ and the primary trial outcome: housing stability. The performance of a new multi-dimensional standardized observer-rated housing quality scale (the OHQS) in a relatively large cross-site sample was also of interest. HQ was rated by trained research assistants for 204 HF participants and 228 TAU participants using the OHQS. General linear regression models were used to examine unit/building quality scores by group and site adjusting for other group differences, and as a predictor of housing stability outcomes after 24 months of follow-up. The OHQS was found to have good reliability and validity, but because most of the neighborhood subscale items were negatively correlated with the overall scale, only unit and building items were included in the total HQ score (possible scores ranging from 13.5 to 135). Unit/building HQ was significantly better for the HF group overall (91.2 (95 % CI = 89.6-92.9) vs. 88.3 (95 % CI = 86.1-90.5); p = .036), and in one site. HQ in the TAU group was much more variable than the HF group overall (W (mean) = 24.7; p < .001) and in four of five sites. Unit/building HQ scores were positively associated with housing stability: (73.4 (95 % CI 68.3-78.5) for those housed none of the time; 91.1 (95 % CI 89.2-93.0) for those housed some of the time; and 93.1 (95 % CI 91.4-94.9)) for those housed all of the time (F = 43.9 p < .001). This association held after adjusting for site, housing characteristics, participant ethnocultural status, community functioning, and social support. This study demonstrates that HQ can be as good or better, and less variable, in HF programs in Canada that systematically and predominantly source housing stock from the private sector compared to housing procured outside of an HF program. HQ is also an important predictor of housing stability outcomes.

Abstract
Background The prevalence of food insecurity and food insufficiency is high among homeless people. We investigated the prevalence and correlates of food insecurity among a cohort of homeless adults with mental illness in Vancouver, British Columbia, Canada. Methods Data collected from baseline questionnaires in the Vancouver At Home study were analysed to calculate the prevalence of food insecurity within the sample (n = 421). A modified version of the U.S. Department of Agriculture’s Adult Food Security Survey Module was used to ascertain food insecurity. Univariable and multivariable logistic regression were used to examine potential correlates of food insecurity. Results The prevalence of food insecurity was 64%. In the multivariable model, food insecurity was significantly associated with age (adjusted odds ratio [aOR] = 0.97; 95% CI: 0.95–0.99), less than high school completion (aOR = 0.57; 95% CI: 0.35–0.93), needing health care but not receiving it (aOR = 1.65; 95% CI: 1.00–2.72), subjective mental health (aOR = 0.97; 95% CI: 0.96–0.99), having spent over $500 for drugs and alcohol in the past month (aOR = 2.25; 95% CI: 1.16–4.36), HIV/AIDS (aOR = 4.20; 95% CI: 1.36–12.96), heart disease (aOR = 0.39; 95% CI: 0.16–0.97) and having gone to a drop-in centre, community meal centre or program/food bank (aOR = 1.65; 95% CI: 1.01–2.68). Conclusions The prevalence of food insecurity was extremely high in a cohort with longstanding homelessness and serious mental illness. Younger age, needing health care but not receiving it, poorer subjective mental health, having spent over $500 for drugs and alcohol in the past month, HIV/AIDS and having gone to a drop-in centre, community meal centre or program/food bank each increased odds of food insecurity, while less than high school completion and heart disease each decreased odds of food insecurity. Interventions to reduce food insecurity in this population are urgently needed.

Abstract
Homeless people have complex problems. GP enhanced care (Pathway) has shown benefits. We performed a randomised, -parallel arm trial at two large inner city hospitals. Inpatient homeless adults were randomly allocated to either standard care (all management by the hospital-based clinical team) or enhanced care with input from a homeless care team. The hospital data system provided healthcare usage information, and we used questionnaires to assess quality of life. 206 patients were allocated to enhanced care and 204 to usual care. Length of stay (up to 90 days after admission) did not differ between groups (standard care 14.0 days, enhanced care 13.3 days). Average reattendance at the emergency department within a year was 5.8 visits in the standard care group and 4.8 visits with enhanced care, but this decrease was not significant. -Quality of life scores after discharge (in 108 patients) improved with enhanced care (EQ-5D-5L score increased by 0.12 [95% CI 0.032 to 0.22] compared wtih 0.03 [-0.1 to 0.15; p=0.076] with standard care). The proportion of people sleeping on the streets after discharge was 14.6% in the standard care arm and 3.8% in the enhanced care arm (p=0.034). The quality-of-life cost per quality-adjusted life-year was £26,000. The Pathway approach doesn't alter length of stay but improves quality of life and reduces street -homelessness.

Abstract
AIMS A subset of people with co-occurring substance use and mental disorders require coordinated support from health, social welfare and justice agencies to achieve diversion from homelessness, criminal recidivism and further health and social harms. Integrated models of care are typically concentrated in large urban centres. The present study aimed to empirically measure the prevalence and distribution of complex co-occurring disorders (CCD) in a large geographic region that includes urban as well as rural and remote settings. METHODS Linked data were examined in a population of roughly 3.7 million adults. Inclusion criteria for the CCD subpopulation were: physician diagnosed substance use and mental disorders; psychiatric hospitalisation; shelter assistance; and criminal convictions. Prevalence per 100 000 was calculated in 91 small areas representing urban, rural and remote settings. RESULTS 2202 individuals met our inclusion criteria for CCD. Participants had high rates of hospitalisation (8.2 admissions), criminal convictions (8.6 sentences) and social assistance payments (over $36 000 CDN) in the past 5 years. There was wide variability in the geographic distribution of people with CCD, with high prevalence rates in rural and remote settings. CONCLUSIONS People with CCD are not restricted to areas with large populations or to urban settings. The highest per capita rates of CCD were observed in relatively remote locations, where mental health and substance use services are typically in limited supply. Empirically supported interventions must be adapted to meet the needs of people living outside of urban settings with high rates of CCD.

Abstract
BACKGROUND Self-reported service use is an integral feature of interventional research with people who are homeless and mentally ill. The objective of this study was to investigate the accuracy of self-reported involvement with major categories of publicly funded services (health, justice, social welfare) within this sub-population. METHODS Measures were administered pre-randomization in two randomized controlled trials, using timeline follow back with calendar aids for Health, Social, and Justice Service Use, compared to linked administrative data. Variables examined were: psychiatric admissions (both extended stays of more than 6 months and two or more stays within 5 years); emergency department visits, general hospitalization and jail in the past 6 months; and income assistance in the past 1 month. Participants (n = 433) met criteria for homelessness and a least one mental illness. RESULTS Prevalence adjusted and bias adjusted kappa (PABAK) values ranged between moderate and almost perfect for extended psychiatric hospital separations (PABAK: 0.77; 95 % confidence interval (CI) = 0.71, 0.83), multiple psychiatric hospitalizations (PABAK = 0.50, 95 % CI = 0.41, 0.59), emergency department visits (PABAK: 0.77; 95 % CI = 0.71, 0.83), jail (PABAK: 0.74; 95 % CI = 0.68, 0.81), and income assistance (PABAK: 0.82; 95 % CI = 0.76, 0.87). Significant differences in under versus over reporting were also found. CONCLUSIONS People who are homeless and mentally ill reliably reported their overall use of health, justice, and income assistance services. Evidence of under-reporting and over-reporting of certain variables has implications for specific research questions. ISRCTN registry: 57595077 (Vancouver at Home Study: Housing First plus Assertive Community Treatment versus congregate housing plus supports versus treatment as usual); and 66721740 (Vancouver at Home study: Housing First plus Intensive Case management versus treatment as usual).

Abstract
Background Homelessness is associated with a very high prevalence of substance use and mental disorders and elevated levels of acute health service use. Among the homeless, little is known regarding the relative impact of specific mental disorders on healthcare utilization. The aim of the present study was to examine the association between different categories of diagnosed mental disorders with hospital admission and length of stay (LOS) in a cohort of homeless adults in Vancouver, Canada. Methods Participants were recruited as part of an experimental trial in which participants met criteria for both homelessness and mental illness. Administrative data were obtained (with separate consent) including comprehensive records of acute hospitalizations during the 10 years prior to recruitment and while participants where experiencing homelessness. Generalized Estimating Equations were used to estimate the associations between outcome variables (acute hospital admissions and LOS) and predictor variables (specific disorders). Results Among the eligible sample (n = 433) 80 % were hospitalized, with an average of 6.0 hospital admissions and 71.4 days per person during the 10-year observation period. Of a combined total 2601 admissions to hospital, 1982 were psychiatric and 619 were non-psychiatric. Significant (p <0.001) independent predictors of hospital admission and LOS included a diagnosis of schizophrenia or bipolar disorder, as well as high (≥32 service contacts) non-psychiatric medical service use in the community. Conclusions Our results demonstrate that specific mental disorders alongside high non-psychiatric service use were significantly associated with hospital admission and LOS. These findings suggest the importance of screening within the homeless population to identify individuals who may be at risk for acute illness and the implementation of services to promote recovery and prevent repeated hospitalization.

Abstract
OBJECTIVES Little research has investigated the role of migration as a potential contributor to the spatial concentration of homeless people with complex health and social needs. In addition, little is known concerning the relationship between possible migration and changes in levels of service use over time. We hypothesised that homeless, mentally ill individuals living in a concentrated urban setting had migrated from elsewhere over a 10-year period, in association with significant increases in the use of public services. SETTING Recruitment was concentrated in the Downtown Eastside neighbourhood of Vancouver, Canada. PARTICIPANTS Participants (n=433) met criteria for chronic homelessness and serious mental illness, and provided consent to access administrative data. METHODS Linked administrative data were used to retrospectively examine geographic relocation as well as rates of health, justice, and social welfare service utilisation in each of the 10 years prior to recruitment. Generalised estimating equations were used to estimate the effect of migration on service use. RESULTS Over a 10-year period there was significant movement into Vancouver's Downtown Eastside neighbourhood (from 17% to 52% of the cohort). During the same period, there were significant annual increases in community medical services (adjusted rate ratio (ARR) per year=1.08; 95% CI 1.06 to 1.10), hospital admissions (ARR=1.08; 95% CI 1.04 to 1.11), criminal convictions (ARR=1.08; 95% CI 1.03 to 1.13), and financial assistance payments (ARR=1.04; 95% CI 1.03 to 1.06). Migration was significantly associated with financial assistance, but not with other types of services. CONCLUSIONS Significant increases in service use over a 10-year period coincided with significant migration into an urban area where relevant services were concentrated. These results highlight opportunities for early intervention in spatially diverse neighbourhoods to interrupt trajectories marked by worsening health and extremely high service involvement. Further research is urgently needed to investigate the causal relationships between physical migration, health and social welfare, and escalating use of public services.

Abstract
PURPOSE Previous cross-sectional studies have indicated that homeless individuals may present with high rates of suicidal ideation, which are strongly associated with completed suicide. We conducted the first known longitudinal study of suicidal ideation in the homeless. METHODS We used data collected over 24 months in the Vancouver At Home project (N = 497), comprised two randomized-controlled trials of housing interventions for homeless individuals with mental disorders. Presence of suicidal ideation was determined using the Colorado symptom index. RESULTS Suicidal ideation significantly decreased over time [odds ratio (OR) = 0.31 at 24 months, 95 % confidence interval (CI) 0.21-0.46]. Baseline diagnoses of mood (OR = 2.18, 95 % CI 1.48-3.21) and anxiety disorders (OR = 2.05, 95 % CI 1.42-2.97), as well as depressive mood (OR = 2.52, 95 % CI 1.90-3.33), use of any substance (OR = 1.59, 95 % CI 1.09-2.32), and polysubstance use (OR = 1.90, 95 % CI 1.40-2.60) were significantly associated with suicidal ideation in the multivariate model. Baseline diagnosis of a psychotic disorder (protective effect), daily substance use, intravenous drug use, recent arrest, multiple physical illnesses and history of traumatic brain injury were significantly associated with suicidal ideation in the unadjusted model only. CONCLUSIONS Interventions targeting depressive symptoms and substance use could help decrease suicide risk in homeless individuals. Mental health services need to be tailored to address the complex needs of socially marginalized individuals. TRIAL REGISTRATION Current controlled trials: ISRCTN57595077 (Vancouver At Home study: Housing First plus Assertive Community Treatment versus congregate housing plus supports versus treatment as usual) and ISRCTN66721740 (Vancouver At Home study: Housing first plus intensive case management versus treatment as usual).

Abstract
AIMS Housing First (HF) is an established intervention for people experiencing homelessness and mental illness. We compared daily substance use (DSU) between HF and treatment as usual (TAU). DESIGN Two concurrent randomized controlled trials with 24-month follow-up. SETTING Market rental apartments with support provided by Assertive Community Treatment (ACT) or Intensive Case Management (ICM); a single building with on-site supports (CONG); TAU in Vancouver, Canada. PARTICIPANTS Inclusion criteria were current homelessness and mental illness. Participants were assessed as having either 'high needs' (HN; n = 297) or 'moderate needs' (MN; n = 200). MN participants were randomized to ICM (n = 100) or MN-TAU (n = 100). HN participants were randomized to ACT (n = 90), CONG (n = 107) or HN-TAU (n = 100). INTERVENTIONS AND COMPARATORS All HF interventions included independent housing with support services, with an emphasis on promoting client choice and harm reduction in relation to substance use. TAU included existing services and support available to homeless adults with mental illness. MEASUREMENTS DSU over 24 and 12 months was derived from the Maudsley Addiction Profile. Also measured were demographics, homelessness history, psychiatric diagnoses, symptom severity, comorbid illnesses and duration of stable housing. FINDINGS Compared with HN-TAU, neither CONG [adjusted odds (AOR) ratio = 0.73, 95% confidence interval (CI) = 0.39-1.37] nor ACT (AOR = 1.22, 95% CI = 0.61-2.45) differed on DSU at 24 months, and MN-TAU did not differ from ICM (AOR = 0.78, 95% CI = 0.37-1.63). There were no differences at 12 months, when analyses were restricted to participants who indicated substance use at baseline, or when considering the duration of stable housing. CONCLUSIONS Housing First, an intervention to support recovery for homeless people who have co-occurring mental illness and substance use disorders, did not reduce daily substance use compared with treatment as usual after 12 or 24 months.

Addict Sci Clin Pract 2015; 10:17. [PMID: 26242968 PMCID: PMC4636835 DOI: 10.1186/s13722-015-0038-1] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2014] [Accepted: 07/16/2015] [Indexed: 11/14/2022] Open
Abstract
Background Homelessness, substance use, and mental disorders each have been associated with higher rates of emergency department (ED) use and hospitalization. We sought to understand the correlation between ED use, hospital admission, and substance dependence among homeless individuals with concurrent mental illness who participated in a ‘Housing First’ (HF) intervention trial. Methods The Vancouver At Home study consisted of two randomized controlled trials addressing homeless individuals with mental disorders who have “high” or “moderate” levels of need. Substance dependence was determined at baseline prior to randomization, using the Mini International Neuropsychiatric Interview diagnostic tool, version 6.0. To assess health service use, we reviewed the number of ED visits and the number of hospital admissions based on administrative data for six urban hospitals. Negative binomial regression modeling was used to test the independent association between substance dependence and health service use (ED use and hospitalization), adjusting for HF intervention, age, gender, ethnicity, education, duration of lifetime homelessness, mental disorders, chronic health conditions, and other variables that were selected a priori to be potentially associated with use of ED services and hospital admission. Results Of the 497 homeless adults with mental disorders who were recruited, we included 381 participants in our analyses who had at least 1 year of follow-up and had a personal health number that could be linked to administrative health data. Of this group, 59% (n = 223) met criteria for substance dependence. We found no independent association between substance dependence and ED visits or hospital admissions [rate ratio (RR) = 0.85; 95% CI 0.62–1.17 and RR = 1.21; 95% CI 0.83–1.77, respectively]. The most responsible diagnoses (defined as the diagnosis that accounts for the length of stay) for hospital admissions were schizo-affective disorder, schizophrenia-related disorder, or bipolar affective disorder; collectively reported in 48% (n = 263) of admissions. Fifteen percent (n = 84) of hospital admissions listed substance dependence as the most responsible diagnosis. Conclusions Substance dependence was not independently associated with ED use or hospital admission among homeless adults with mental disorders participating in an HF trial. Hospital admissions among this cohort were primarily associated with severe mental disorders. Trial registration: ISRCTN57595077 and ISRCTN66721740

The impact of mood symptomatology on pattern of substance use among homeless. J Affect Disord 2015; 176:164-70. [PMID: 25723559 DOI: 10.1016/j.jad.2015.01.059] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2014] [Revised: 01/28/2015] [Accepted: 01/29/2015] [Indexed: 02/02/2023]
Abstract
BACKGROUND Homeless individuals are an extremely vulnerable and underserved population characterized by overlapping problems of mental illness and substance use. Given the fact that mood disorders are frequently associated with substance use disorders, we wanted to further highlight the role of excitement in substance abuse. Patterns of substance abuse among homeless suffering from unipolar and bipolar depression were compared. The "self-medication hypothesis" which would predict no-differences in substance preference by unipolar (UP) and bipolar (BP) depressed homeless was tested. METHODS Homeless individuals from the Vancouver At Home/Chez Soi study were selected for lifetime UP and lifetime BP depression and patterns of substances abused in the previous 12 months were identified with the Mini-International Neuropsychiatric Interview. Differences in substance use between BP-depressed homeless and UP-depressed homeless were tested using Chi-square and logistic regression techniques. RESULTS No significant differences were observed between UP and BP homeless demographics. The bipolar depressed homeless (BDH) group displayed a higher percentage of Central Nervous System (CNS) Stimulants (χ 8.66, p=0.004) and Opiates (χ 6.41, p=0.013) as compared to the unipolar depressed homeless (UDH) group. CSN Stimulant was the only predictor within the BDH Group (χ(2) 8.74 df 1 p<0.003). LIMITATIONS Data collected are self-reported and no urinalyses were performed. CONCLUSIONS The results support the hypothesis that beyond the self-medication hypothesis, bipolarity is strictly correlated to substance use; this correlation is also verified in a homeless population.

Abstract
BACKGROUND It is well documented that a disproportionate number of homeless adults have childhood histories of foster care placement(s). This study examines the relationship between foster care placement as a predictor of adult substance use disorders (including frequency, severity and type), mental illness, vocational functioning, service use and duration of homelessness among a sample of homeless adults with mental illness. We hypothesize that a history of foster care predicts earlier, more severe and more frequent substance use, multiple mental disorder diagnoses, discontinuous work history, and longer durations of homelessness. METHODS This study was conducted using baseline data from two randomized controlled trials in Vancouver, British Columbia for participants who responded to a series of questions pertaining to out-of-home care at 12 months follow-up (n = 442). Primary outcomes included current mental disorders; substance use including type, frequency and severity; physical health; duration of homelessness; vocational functioning; and service use. RESULTS In multivariable regression models, a history of foster care placement independently predicted incomplete high school, duration of homelessness, discontinuous work history, less severe types of mental illness, multiple mental disorders, early initiation of drug and/or alcohol use, and daily drug use. CONCLUSIONS This is the first Canadian study to investigate the relationship between a history of foster care and current substance use among homeless adults with mental illness, controlling for several other potential confounding factors. It is important to screen homeless youth who exit foster care for substance use, and to provide integrated treatment for concurrent disorders to homeless youth and adults who have both psychiatric and substance use problems. TRIALS REGISTRATION NUMBERS Both trials are registered with the International Standard Randomized Control Trial Number Register and were assigned ISRCTN57595077 (Vancouver At Home Study: Housing First plus assertive community treatment versus congregate housing plus supports versus treatment as usual) and ISRCTN66721740 (Vancouver At Home Study: Housing First plus intensive case management versus treatment as usual) on September 9, 2012.

Abstract
BACKGROUND People experiencing homelessness and mental illness face multiple barriers to care. The goal of this study was to examine the association between health service use and indicators of need among individuals experiencing homelessness and mental illness in Vancouver, Canada. We hypothesized that those with more severe mental illness would access greater levels of primary and specialist health services than those with less severe mental illness. METHODS Participants met criteria for homelessness and current mental disorder using standardized criteria (n = 497). Interviews assessed current health status and involvement with a variety of health services including specialist, general practice, and emergency services. The 80th percentile was used to differentiate 'low health service use' and 'high health service use'. Using multivariate logistic regression analysis, we analyzed associations between predisposing, enabling and need-related factors with levels of primary and specialist health service use. RESULTS Twenty-one percent of participants had high primary care use, and 12% had high use of specialist services. Factors significantly (p ≤ 0.05) associated with high primary care use were: multiple physical illnesses [AOR 2.74 (1.12, 6.70]; poor general health [AOR 1.68 (1.01, 2.81)]; having a regular family physician [AOR 2.27 (1.27, 4.07)]; and negative social relationships [AOR 1.74 (1.01, 2.99)]. Conversely, having a more severe mental disorder (e.g. psychotic disorder) was significantly associated with lower odds of high service use [AOR 0.59 (0.35, 0.97)]. For specialist care, recent history of psychiatric hospitalization [AOR 2.53 (1.35, 4.75)] and major depressive episode [AOR 1.98 (1.11, 3.56)] were associated with high use, while having a blood borne infectious disease (i.e., HIV, HCV, HBV) was associated with lower odds of high service use. CONCLUSIONS Contrary to our hypotheses, we found that individuals with greater assessed need, including more severe mental disorders, and blood-borne infectious diseases had significantly lower odds of being high health service users than those with lower assessed needs. Our findings reveal an important gap between levels of need and service involvement for individuals who are both homeless and mentally ill and have implications for health service reform in relation to the unmet and complex needs of a marginalized sub-population.

Abstract
This study examines community integration among homeless adults with mental illness 6 and 12 months after random assignment to Housing First (independent apartments or congregate residence) with support services or to treatment as usual (TAU). Residence in independent apartments was associated with increased 'psychological integration' for participants with less severe needs; however, no significant improvement in 'physical integration' was observed among any of the intervention groups. Analysis of individual items on the Psychological Integration subscale revealed that, compared to TAU, participants assigned to independent apartments were more likely to endorse statements related to the emotional components of community but not statements related to neighboring. Participants assigned to the congregate residence were more likely to endorse knowing their neighbors, but not interacting with neighbors or the emotional components of community. Findings are discussed in terms of housing program as well as broader contextual factors.

Abstract
BACKGROUND It is well documented that childhood abuse, neglect and household dysfunction are disproportionately present in the backgrounds of homeless adults, and that these experiences adversely impact child development and a wide range of adult outcomes. However, few studies have examined the cumulative impact of adverse childhood experiences on homeless adults with mental illness. This study examines adverse events in childhood as predictors of duration of homelessness, psychiatric and substance use disorders, and physical health in a sample of homeless adults with mental illness. METHODS This study was conducted using baseline data from a randomized controlled trial in Vancouver, British Columbia for participants who completed the Adverse Childhood Experiences (ACE) scale at 18 months follow-up (n=364). Primary outcomes included current mental disorders; substance use including type, frequency and severity; physical health; duration of homelessness; and vocational functioning. RESULTS In multivariable regression models, ACE total score independently predicted a range of mental health, physical health, and substance use problems, and marginally predicted duration of homelessness. CONCLUSIONS Adverse childhood experiences are overrepresented among homeless adults with complex comorbidities and chronic homelessness. Our findings are consistent with a growing body of literature indicating that childhood traumas are potent risk factors for a number of adult health and psychiatric problems, particularly substance use problems. Results are discussed in the context of cumulative adversity and self-trauma theory. TRIALS REGISTRATION This trial has been registered with the International Standard Randomized Control Trial Number Register and assigned ISRCTN42520374.
