Neighborhood socioeconomic status and racial disparities in schizophrenia : An exploration of domains of functioning

Black Americans are disproportionately diagnosed with schizophrenia and experience worse objective functional outcomes (e.g., hospitalizations) than their White counterparts. However, we have a limited understanding of the psychological pathways through which Black Americans with schizophrenia reach worse outcomes. This study assessed race and domains of functioning (e.g., neurocognition, functional capacity) known to be associated with objective outcomes in a sample of 108 non-Hispanic Black and 61 non-Hispanic White individuals with schizophrenia-spectrum disorders from the Social Cognition Psychometric Evaluation (SCOPE) study. Three primary findings emerged: First, Black participants showed lower scores than White participants on measures of neurocognition(NC), social cognition(SC), and everyday living skills, but not social skills or community functioning. Second, neighborhood socioeconomic status (SES) explained 21% of the relationship between race and NC but did not mediate the relationship between race and SC or everyday living skills. Finally, prior research has established that NC, SC, social skills, and everyday living skills predict community functioning in individuals. Finally, prior research has established that NC, SC, social skills, and everyday living skills predict community functioning in individuals with schizophrenia. In our sample, after controlling for neighborhood SES, race did not moderate the relationships of NC, SC, social skills, or everyday living skills to community functioning. This indicates that relationships between these domains are comparably strong across Black and White Americans. Taken together, these findings show that NC, SC, and everyday living skills may be important areas to explore in regards to racial disparities in schizophrenia. More research, especially incorporating nuanced race- and SES-related variables, is needed to understand how to best intervene and improve real-world outcomes for Black Americans with schizophrenia.
