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.
