Trauma Symptoms of Individuals with Mental Illness at Risk for Homelessness Participating in a Life Skills Intervention

Competencies for occupational therapy practice in homelessness: A Delphi study

BACKGROUND

Homelessness is growing internationally, and resources to guide occupational therapy practice in this area are needed.

OBJECTIVES

To identify competencies needed for occupational therapists to support individuals during and following homelessness.

MATERIAL AND METHODS

We conducted a three-round Delphi study with occupational therapy practitioners and researchers with expertise in homelessness.

RESULTS

Of 35 potential participants, n = 16 participated in Round I, n = 20 participated in Round II, and n = 18 participated in Round III. Participants included occupational therapists and researchers in Canada, United States, Brazil, UK, Ireland and New Zealand. Consensus was achieved on a total of 93 competencies in 10 categories after 15 were eliminated in Rounds II and III. The categories with the greatest number of competencies included occupational knowledge (n = 18), followed by psychosocial competencies (n = 16).

CONCLUSIONS AND SIGNIFICANCE

This study represents the first to identify the competencies needed for occupational therapists working in the area of homelessness. Practitioners and educators are encouraged to view the identified competencies as a guide for the professional development of occupational therapists in this context. Stakeholders consulted for this study were able to communicate in English and situated in middle to high-income countries. As such, the competencies identified in this study only apply to these sociocultural contexts.

Interventions to treat post-traumatic stress disorder (PTSD) in vulnerably housed populations and trauma-informed care: a scoping review

OBJECTIVES

The goals of this study are to identify and analyse interventions that aim to treat post-traumatic stress disorder (PTSD) and complex PTSD in people who are vulnerably housed and to describe how these treatments have been delivered using trauma-informed care.

DESIGN

Scoping review.

SEARCH STRATEGY

We searched electronic databases including MEDLINE, Embase, PsycINFO, CINAHL, the Cochrane Library, Web of Science and PTSDpubs for published literature up to November 2021 for any studies that examined the treatment of PTSD in adults who were vulnerably housed. Websites of relevant organisations and other grey literature sources were searched to supplement the electronic database search. The characteristics and effect of the interventions were analysed. We also explored how the interventions were delivered and the elements of trauma-informed care that were described.

RESULTS

28 studies were included. We identified four types of interventions: (1) trauma focused psychotherapies; (2) non-trauma psychotherapies; (3) housing interventions and (4) pharmacotherapies. The trauma-informed interventions were small case series and the non-trauma focused therapies included four randomised controlled trials, were generally ineffective. Of the 10 studies which described trauma-informed care the most commonly named elements were physical and emotional safety, the experience of feeling heard and understood, and flexibility of choice. The literature also commented on the difficulty of providing care to this population including lack of private space to deliver therapy; the co-occurrence of substance use; and barriers to follow-up including limited length of stay in different shelters and high staff turnover.

CONCLUSIONS

This scoping review identified a lack of high-quality trials to address PTSD in people who are vulnerably housed. There is a need to conduct well designed trials that take into account the unique setting of this population and which describe those elements of trauma-informed care that are most important and necessary.

A comprehensive review of prioritised interventions to improve the health and wellbeing of persons with lived experience of homelessness

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.

Trauma and healing in the underserved populations of homelessness and corrections: Forgiveness Therapy as an added component to intervention

The purpose of this article is to begin applying the principles of the psychology of forgiveness to people who are without homes and people who are in prisons. A review of the literature shows trauma for both groups. When the trauma is caused by unjust treatment by others, then excessive anger can result, compromising one's psychological and physical health. We review the interventions that have been offered for those without homes and the imprisoned to examine which existing programmes address such anger. Forgiveness Therapy, although untried in these two settings, may be one beneficial approach for substantially reducing unhealthy anger. Forgiveness interventions have shown a cause-and-effect relationship between learning to forgive and overcoming psychological compromise such as strong resentment and clinical levels of anxiety and depression. The literature review here suggests that forgiveness therapy for those without homes and the imprisoned may be a new and important consideration for ameliorating anger and aiding in a changed life pattern.

Empowering Features and Outcomes of Homeless Interventions: A Systematic Review and Narrative Synthesis

The purpose of this systematic review and narrative synthesis was to identify homeless interventions with empowering features and evaluate their effectiveness for developing the psychological empowerment of services users. To identify and evaluate intervention studies, we combined the theoretical frameworks of empowering settings and psychological empowerment (PE). Our conceptualization of PE included outcomes aligned with the intrapersonal, interactional, and behavioral components. Relational outcomes were also included and conceptualized as antecedents for PE development. After systematic searching and screening, 37 studies were included for review. Interventions with empowering features included supported housing, case management, skills and knowledge acquisition, and mutual support. Interventions that were competency-building effectively improved outcomes aligned with the intrapersonal PE component. Interventions that were collaborative and competency-building effectively improved outcomes aligned with the behavioral PE component. Weak evidence suggested that interventions with empowering features may effectively improve outcomes aligned with the interactional PE component. Interventions that promoted and developed support effectively improved relational antecedents. Findings align the empirical evidence for homeless interventions with theoretical conceptions of empowering features and processes. Findings may be applied to the design and implementation of homeless interventions to incorporate empowering features and to facilitate the development of homeless services users' PE. Highlights Empowerment theory was applied to review homeless interventions literature. Empowering homeless interventions included supported housing and mutual support, for example. Empowering interventions contributed to indicators of emotional and behavioral empowerment. Fewer empowering interventions contributed to indicators of cognitive empowerment. Service user involvement may facilitate improvements in indicators of psychological empowerment.

A systematic review of occupational therapy interventions in the transition from homelessness

BACKGROUND

Although systematic and scoping reviews have identified a range of interventions for persons experiencing homelessness, no known reviews have captured the range and quality of intervention studies aimed at supporting a transition from homelessness.

OBJECTIVES

To capture the range and quality of occupational therapy intervention studies aimed at supporting a transition to housing following homelessness.

METHOD

Using Joanna Briggs Institute (JBI) guidelines, we conducted a systematic review including a critical appraisal and narrative synthesis of experimental studies.

RESULTS

Eleven studies were included. Critical appraisal scores ranged from 33.3 to 88.9 of a possible score of 100 (Mdn = 62.5; IQR = 33.4). The majority of studies evaluated interventions for the development of life skills (n = 9; 81.8%), and all were conducted in the USA. Several of the included studies were exploratory evaluation and feasibility studies, and all were quasi-experimental in design. Only three studies (27.2%) incorporated a control group. Intervention strategies included (1) integrated group and individual life skills interventions (n = 6); (2) group-based life skills interventions (n = 3); and (3) psychosocial and consultative interventions (n = 2).

CONCLUSIONS

Research evaluating occupational therapy interventions aimed at supporting homeless individuals as they transition to housing is in an early stage of development.

SIGNIFICANCE

Implications for research and practice are discussed.

Occupational Needs and Goals of Survivors of Domestic Violence

This study's purpose was to describe the occupational needs and goals of women residing in a domestic violence shelter and their self-perceived changes in satisfaction and occupational performance. Using a retrospective design, data from 68 occupational therapy evaluations from two domestic violence shelter settings were examined. Data were analyzed by coding problem areas and occupational goals and calculating frequencies for these variables. Where data were available, we also analyzed changes in pre- and postscores for self-perceived satisfaction and occupational performance (n = 25). The most common problem areas were leisure, education, work, child rearing, and health management. The most common goals were in the areas of education, work, health management, child rearing, and home management. Retrospective pre- and postchange scores in performance and satisfaction for 25 women were statistically significant. Findings provide direction for, and highlight the importance of occupational therapy services within domestic violence shelters as women regain their life skills.

Feasibility and Acceptability of a Pilot Housing Transition Program for Homeless Adults with Mental Illness and Substance Use

The purpose of this study was to determine if a housing transition program was feasible and acceptable to homeless clients with mental illness and substance use histories. Ten male residents of a homeless shelter participated in the 3-week housing intervention. The intervention used a DVD format with instructional videos, graphics, and opportunities for hands-on practice of functional skills in a simulated apartment environment. Outcome measures included goal attainment scale scores (GAS), satisfaction surveys, and case manager reports. Six of the 10 participants completed the program and achieved GAS scores at a greater level than expected at baseline (T > 50). Participants reported the intervention to be engaging and enhanced their knowledge of the housing transition process. The intervention appears to have assisted the participants in the attainment of housing skills and warrants further study.

Change patterns of homeless individuals with mental illness: a multiple case study

This multiple case study illuminates the individual change trajectories of four homeless men with mental illnesses who participated in a manualized life skills intervention to improve housing retention. Readiness-to-change, life skills knowledge and trauma symptoms were measured at baseline, post-intervention and at 3-6 months follow-up. Cluster analysis identified two patterns of readiness-to-change: engaged and pre-engaged. Change is non-linear and baseline readiness is not necessary to benefit from the intervention. Examining individuals' lives in context illuminated the change process and demonstrated that varied patterns can lead to successful outcomes for housing stability and community reintegration.

Psychometric Properties of the Practical Skills Test (PST)

The Practical Skills Test (PST) is a new assessment of individuals' knowledge of life skills. We evaluated the PST's reliability, validity, and sensitivity to change among a homeless population. Participants were 123 homeless persons in a longitudinal experimental study who were assessed before and after intervention with the PST, Allen Cognitive Level Screen-2000 (ACLS-2000), and Impact of Event Scale-Revised (IES-R). The PST showed generally good internal consistency, no floor effects, and limited ceiling effects (<20% on each test). Supportive evidence for the PST's convergent validity was seen in its moderate correlations with the ACLS-2000; we found no significant correlation with the IES-R. Paired t tests indicated that the PST is sensitive to changes in life skills after intervention, but effect sizes were small. The results suggest that the PST has generally good reliability and validity. However, ceiling effects suggest an area for further development.

Readiness-to-change cluster profiles among adults with mental illness who were homeless participating in a life skills intervention

This longitudinal study examined differences in intervention outcomes based on readiness-to-change cluster profiles among 73 adults with a mental illness at risk for homelessness participating in a manualized life skills intervention. Intervention topics included money management, food management, safe community participation, and room- and self-care. Life skill knowledge and readiness-to-change, measured using the University of Rhode Island Change Assessment, was examined at baseline, post-intervention, and 3-6 months later. Two scoring patterns emerged for readiness-to-change at each time point: Pre-Engaged and Engaged. Participants who were Engaged at the time of assessment scored significantly better than Pre-Engaged on post-intervention life skill testing, however group identification changed over time. Baseline readiness-to-change did not predict future performance or attrition, and therefore may not provide accurate indication of client investment for future learning or participation. Further investigation is needed to determine what factors contribute to Engaged membership.
