• Homelessness is a critical public health issue in the United States, especially among homeless veterans. While supported housing helps, community integration remains a challenge, particularly for those with psychotic disorders. Previous research demonstrated that cognitive abilities and motivation are key factors influencing community integration. Limited knowledge exists on determinants affecting social integration (i.e., family relationship, and friendship) and work for homeless veterans. Such information is crucial for tailored interventions. This study employed a secondary analysis to investigate differences in these factors' associations with family, friendship, and employment among homeless veterans with and without psychosis. Initially, a total of 97 homeless veterans with a psychotic disorder and 82 without psychosis were assessed before receiving housing, with 54 of the participants with psychosis and 41 of the participants without psychosis returning after 12 months. Cross-sectional and longitudinal analyses revealed various correlations between determinants and community integration in both samples. Notably, different potential causal relationships were observed in the groups. Motivation appeared to influence family relationships in participants with psychosis, while in those without, there was a trend that friends and work engagement influenced social cognition. Work engagement before receiving housing also positively impacted motivational attitudes at the 12-month mark in the non-psychosis group. These findings across samples emphasize the importance of considering the distinct needs and challenges faced by homeless veterans with and without psychosis in providing interventions for their social integration and employment.
