Existing disparities regarding Black Americans' psychological health warrant further investigation of socioecological factors that may be associated with negative and positive dimensions of psychological health in this population. Romantic relationship functioning and neighborhood context are two domains relevant to Black Americans' mental health. However, less is known about how they may serve as independent and interactive prospective predictors of Black Americans' psychological health and potentially in distinctive ways for Black men and women. Using data from 333 partnered Black Americans who participated in the Midlife in the United States study, we investigated relationship adjustment and neighborhood quality as independent and interactive predictors of negative and positive affect 10 years later and examined gender differences in these linkages. Higher neighborhood quality predicted lower levels of negative affect and higher levels of positive affect for both men and women a decade later. Additionally, for Black men, the longitudinal association between relationship adjustment and negative affect differed by neighborhood quality such that better relationship adjustment predicted higher subsequent negative affect only for men in lower quality neighborhoods. Findings demonstrate the connections among romantic relationship functioning, ecological resources, and gender in this population and highlight the importance of incorporating socioecological and intersectional perspectives for predicting Black Americans' long-term psychological health. General Scientific Summary: This study suggests that living in higher quality neighborhoods is related to greater positive aspects and lower negative aspects of psychological health over time for Black Americans. Moreover, for Black men specifically, better romantic relationship functioning is connected to poorer psychological health when they reside in lower quality neighborhoods. [ABSTRACT FROM AUTHOR]

This study examines day-to-day variability in psychometrically defined mild cognitive impairment (MCI) status and potential predictors of changes in MCI status in an independent-living sample of urban dwelling older adults in Baltimore, Maryland. The participant sample consisted of 50 older adults, ranging in age from 50 to 80 years. Participants completed health and cognitive measures (i.e., executive function, language, memory, and global cognition) over 8 occasions within a 2-3-week period. After each testing occasion, a post hoc classification of MCI status was determined using psychometrically defined criteria based on cognitive performance. Participants who classified as MCI after one assessment often did not meet MCI criteria at subsequent occasions. Daily fluctuations in sleep duration were associated with an increased risk for MCI classification. These results demonstrate that changes in sleep may explain changes in MCI status, particularly for African Americans. [ABSTRACT FROM AUTHOR]

This study examined the within-person relationship between sleep and cognitive functioning. Fifty community-dwelling African Americans (age range 50-80 years) were asked to report their sleep duration and quality the previous evening and to complete cognitive measures over 8 occasions within a 2-3 week period. A within-person daily change in sleep duration was significantly associated with worse global cognitive performance. The greater an individual deviated away from his or her average sleep duration on a particular day, the more likely his or her performance would decline. These results demonstrate that the sleep-cognition relationship can be observed at a within-person level of analysis. [ABSTRACT FROM AUTHOR]
