Motivational and cognitive correlates of community integration in homeless veterans entering a permanent supported housing program

Neuropsychological functioning, neurobehavioral symptoms, and community reintegration in unstably housed veterans with mental health conditions

Objective: Returning Veterans often have conditions (e.g. posttraumatic stress disorder [PTSD], depression, and history of traumatic brain injury [TBI]) associated with cognitive dysfunction and problems with work, school, housing, and relationships. Rehabilitative efforts in Veterans aim to promote community reintegration, or successful adjustment in one's home, community, and desired social roles. We examined associations between neuropsychological performance, neurobehavioral symptoms, and community reintegration in Veterans. Method: 89 Iraq/Afghanistan Veterans at risk for homelessness and receiving residential mental healthcare completed a neuropsychological assessment and the Community Reintegration for Service Members-Computer Adaptive Test (CRIS-CAT). Neuropsychological components were derived using Principal Component Analysis. Bivariate Pearson correlations between neuropsychological variables, neurobehavioral symptoms, and CRIS-CAT scales (Extent of Participation, Perceived Limitations, and Satisfaction) were used to determine significant correlates of community reintegration. Regression models were used to examine associations between bivariate-significant neuropsychological components, neurobehavioral symptoms, and CRIS-CAT scales. Results: Bivariate analyses revealed that better community reintegration was associated with better performance in attention/executive functioning and fewer neurobehavioral symptoms. Three regression models examining predictors of variance in Extent of Participation, Perceived Limitations, and Satisfaction in community reintegration were statistically significant overall, with only fewer affective symptoms emerging as significantly and uniquely associated with greater participation and greater satisfaction in community functioning. Conclusions: Veterans with fewer affective symptoms reported greater participation and satisfaction with community functioning. Future longitudinal research examining associations between neurobehavioral symptoms, cognition, and risk factors of poorer community reintegration in unstably housed Veterans is warranted.

Memory, fluid reasoning, and functional capacity in adults experiencing homelessness

BACKGROUND AND OBJECTIVE

In individuals experiencing homelessness, determinants of functional capacity (i.e. the ability to perform activities of daily living) are poorly understood. Identifying potentially modifiable correlates of functional capacity, such as cognitive abilities, may inform treatment targets to address independence and housing stability. This study aimed to identify the strongest neuropsychological predictors of variance in functional performance in 100 adults living in a homeless shelter.

METHODS

Participants completed a brief cognitive screening test, from which four composite scores were derived, as well as tests of processing speed, fluid reasoning, premorbid intellectual function, and performance-based functional capacity. We conducted a hierarchical linear regression to predict variance in functional capacity.

RESULTS

Beyond the impact of education and premorbid intellectual function, better memory and fluid reasoning predicted better functional performance.

CONCLUSIONS

Although our cross-sectional design does not permit causal inference, it is possible that interventions targeting memory and fluid reasoning may improve functional ability in individuals experiencing homelessness.

Disparities in program enrollment and employment outcomes for veterans with psychiatric and co-occurring substance use disorders referred or enrolled for VHA vocational rehabilitation

Introduction

The purpose of the study was to investigate factors that influence vocational rehabilitation program enrollment and employment at discharge of veterans with psychiatric and co-occurring alcohol and other substance use disorders enrolled at a veteran health administration (VHA) medical center.

Methods

A sample of 2,550 veteran patients referred for VHA vocational rehabilitation between 2016 and 2021 were examined for the current study. The current study was classified as quality improvement/assurance, thus resulting in exempt research by the U.S. Department of Veteran Affairs Institutional Review Board.

Results

Veterans with active alcohol use disorders (AUDs) and co-occurring depression, anxiety, post-traumatic stress disorder, or bipolar disorders were less likely to be enrolled for vocational rehabilitation program services compared to those without these co-occurring diagnoses. Veterans with AUD (active & in-remission status combined into one category) and a diagnosis of anxiety were less likely to be employed at discharge compared to veterans with AUDs and no anxiety diagnosis (anxiety diagnosis - 3.5% vs. no anxiety diagnosis - 5.8%).

Discussion

VHA vocational rehabilitation can be an effective intervention to assist veterans in reintegrating back into the community. Yet, there appears to be some disparities in the program enrollment and employment at discharge, depending on the nature of the psychiatric diagnosis. Investigating the factors contributing (mediating or moderating) to these discrepancies are needed. Although it appears access is not the issue in being referred for vocational rehabilitation services, other factors are likely contributing to program entry.

An Australian aged care home for people subject to homelessness: health, wellbeing and cost-benefit

BACKGROUND

Older people subject to homelessness face many challenges including poor health status, geriatric syndromes, and depression, coupled with barriers in accessing health and aged care services. Many are in need of formal aged care at a younger age than the general population, yet, in Australia, specialised aged-care services to support this vulnerable cohort are limited.

METHODS

This study was an evaluation of a new purpose-built aged care home for people with high care needs and who are homeless or at risk of homelessness. Over the first 12 months post-admission, the study examined: (1) changes in residents' physical, mental, psychological and social health, and (2) the costs incurred by the study cohort, including any cost benefit derived.

RESULTS

Thirty-five residents enrolled in the study between March 2020 - April 2021. At admission, almost half of residents were within the range for dementia, the majority were frail, at high risk for falls, and had scores indicative of depression. Over time, linear mixed-effect models showed significant improvement in personal wellbeing scores, with clinically significant improvements in overall health related quality of life. Levels of physical functional independence, frailty, and global cognition were stable, but cognitive functional ability declined over time. Comparison of 12 month pre- and post- admission cost utility data for a smaller cohort (n = 13) for whom complete data were available, suggested an average per resident saving of approximately AU$32,000, while the QALY indicators remained stable post-admission.

CONCLUSION

While this was a small study with no control group, these preliminary positive outcomes add to the growing body of evidence that supports the need for dedicated services to support older people subject to homelessness.

Cognitive determinants of community functioning and quality of life in homeless adults with mental illness: 6-year follow-up from the At Home/Chez Soi Study Toronto site

BACKGROUND

High rates of physical and mental health comorbidities are associated with functional impairment among persons who are homeless. Cognitive dysfunction is common, but how it contributes to various functional outcomes in this population has not been well investigated. This study examines how cognition covaries with community functioning and subjective quality of life over a 6-year period while accounting for the effects of risk and protective factors.

METHODS

Participants were 349 homeless adults (mean age = 39.8) recruited from the Toronto site of the At Home/Chez Soi study, a large Canadian randomized control trial of Housing First. Participants completed up to four clinical evaluations over 6 years. Factor scores were created to index verbal learning and memory (vLM) and processing speed-cognitive flexibility (PSCF). The primary outcomes were community functioning and subjective quality of life. Risk factors included lifetime homelessness, mental health diagnoses, medical comorbidity, and childhood adversity. Linear mixed-effects models were conducted to examine cognition-functional outcome associations over time, with resilience as a moderator.

RESULTS

Better vLM (b = 0.787, p = 0.010) and PSCF (b = 1.66, p < 0.001) were associated with better community functioning, but not with quality of life. Resilience conferred a protective effect on subjective quality of life (b = 1.45, p = 0.011) but did not moderate outcomes.

CONCLUSIONS

Our findings suggest a need to consider the unique determinants of community functioning and quality of life among homeless adults. Cognition should be prioritized as a key intervention target within existing service delivery models to optimize long-term functional outcomes.

Examining racial differences in community integration between black and white homeless veterans

Black Americans are overrepresented in Veteran and non-Veteran homeless populations. Community integration remains a problem for many Veterans after they obtain housing, and Black Veterans may encounter additional difficulties due to systemic racism. However, no prior study has specifically examined whether there are racial differences in community integration; similarly, no study has considered racial differences in psychosocial correlates of community integration in homeless Veterans. Knowledge of these factors could inform the development of culturally congruent rehabilitative interventions for Black Veterans. Semi-structured clinical interviews were administered to Black (N = 99) and White (N = 49) homeless Veterans to examine relations among psychiatric symptoms, motivation, and community integration domains (e.g., social integration, work productivity, and independent living). There were no significant racial differences in independent living or work productivity. Black Veterans had better social integration with family compared to White Veterans. In addition, psychiatric symptoms were more strongly correlated with social integration for Black than White Veterans. The association between motivation and work productivity was also stronger for Black Veterans. Recovery-oriented interventions could harness family connections and better target psychiatric symptoms to improve community integration for Black Veterans. Work productivity may improve from interventions aimed at enhancing motivation for Black Veterans.

Motivational and cognitive factors linked to community integration in homeless veterans: study 1 - individuals with psychotic disorders

BACKGROUND

Little is known about the determinants of community integration (i.e. recovery) for individuals with a history of homelessness, yet such information is essential to develop targeted interventions.

METHODS

We recruited homeless Veterans with a history of psychotic disorders and evaluated four domains of correlates of community integration: perception, non-social cognition, social cognition, and motivation. Baseline assessments occurred after participants were engaged in supported housing services but before they received housing, and again after 12 months. Ninety-five homeless Veterans with a history of psychosis were assessed at baseline and 53 returned after 12 months. We examined both cross-sectional and longitudinal relationships with 12-month community integration.

RESULTS

The strongest longitudinal association was between a baseline motivational measure and social integration at 12 months. We also observed cross-sectional associations at baseline between motivational measures and community integration, including social, work, and independent living. Cross-lagged panel analyses did not suggest causal associations for the motivational measures. Correlations with perception and non-social cognition were weak. One social cognition measure showed a significant longitudinal correlation with independent living at 12 months that was significant for cross-lagged analysis, consistent with a causal relationship and potential treatment target.

CONCLUSIONS

The relatively selective associations for motivational measures differ from what is typically seen in psychosis, in which all domains are associated with community integration. These findings are presented along with a partner paper (Study 2) to compare findings from this study to an independent sample without a history of psychotic disorders to evaluate the consistency in findings regarding community integration across projects.

Motivational and cognitive factors linked to community integration in homeless veterans: Study 2 - clinically diverse sample

BACKGROUND

In an initial study (Study 1), we found that motivation predicted community integration (i.e. functional recovery) 12 months after receiving housing in formerly homeless Veterans with a psychotic disorder. The current study examined whether the same pattern would be found in a broader, more clinically diverse, homeless Veteran sample without psychosis.

METHODS

We examined four categories of variables as potential predictors of community integration in non-psychotic Veterans: perception, non-social cognition, social cognition, and motivation at baseline (after participants were engaged in a permanent supported housing program but before receiving housing) and a 12-month follow-up. A total of 82 Veterans had a baseline assessment and 41 returned for testing after 12 months.

RESULTS

The strongest longitudinal association was between an interview-based measure of motivation (the motivation and pleasure subscale from the Clinical Assessment Interview for Negative Symptoms) at baseline and measures of social integration at 12 months. In addition, cross-lagged panel analyses were consistent with a causal influence of general psychiatric symptoms at baseline driving social integration at 12 months, and reduced expressiveness at baseline driving independent living at 12 months, but there were no significant causal associations with measures of motivation.

CONCLUSIONS

The findings from this study complement and reinforce those in Veterans with psychosis. Across these two studies, our findings suggest that motivational factors are associated at baseline and at 12 months and are particularly important for understanding and improving community integration in recently-housed Veterans across psychiatric diagnoses.

Determinants of Community Integration Among Formerly Homeless Veterans Who Received Supportive Housing

Community integration is recognized as a meaningful goal that is highly relevant to the long-term success of supportive housing programs. Research to date highlights concerns that some individuals in permanent supportive housing remain socially isolated and have limited success in other domains of community integration. However, we know little about what factors impact formerly homeless veterans' ability to achieve community integration. To identify factors associated with community integration among homeless veterans housed through the Department of Veterans Affairs' (VA's) Supportive Housing program (HUD-VASH), we performed secondary database analyses of Veterans (n = 560) housed via HUD-VASH in the VA Greater Los Angeles Healthcare System from 10/1/14-9/30/15. We conducted ordinal and logit regressions to examine associations between baseline HUD-VASH participant characteristics, supportive housing voucher type, health service utilization in the year post-housing, and three types of community integration outcomes (i.e., change in community adjustment, status of housing stability, and change in employment). Data were obtained from HOMES (VA's homeless registry) and Corporate Data Warehouse (CDW) (VA's a national administrative dataset of VA inpatient and outpatient care). Mental health service utilization was negatively associated with community adjustment, housing stability, and employment. Employment at baseline was positively associated with housing stability and employment. Also, substance use disorder visits was positively associated with employment, and combined medical and substance use disorder diagnoses was positively associated with change in community adjustment. We considered 29 variables and found relatively few were associated with community integration. Consistent with previous research, our study highlights the importance of mental health needs, and suggests that utilization of mental health services is an important indicator of improvements in community adjustment, housing stability, and employment.
