Stress Biomarkers in Black Youth: Exploring Psychological, Behavioral, and Socio-Ecological Correlates.

Exposure to chronic stress is a major public health concern. Black youth are vulnerable to chronic stress exposure given their overrepresentation in urban neighborhoods characterized by socio-ecological stressors. We contribute to this emerging body of knowledge by (1) investigating stress-induced variability in cortisol response patterns among Black youth, and (2) examining risk and protective factors associated with physiological stress responses. Salivary cortisol was collected from a community sample of 123 low-income Black youth ages 13 to 21. Latent class analysis (LCA) and logistic regression were utilized to identify discrete groups based on cortisol reactivity, and psychological, behavioral, and socio-ecological correlates of class membership. LCA supported a 2-class model of cortisol reactivity. Youth in class one were indicative of a normative stress response with mean cortisol awakening response of 0.38 µg/dL (SD = 0.19), 0.48 µg/dL (SD = 0.20) at time 2, and 0.44 µg/dL (SD = 0.20) at time 3. Youth in class two exhibited a blunted stress response with mean cortisol awakening response of 0.20 µg/dL (SD = 0.11), 0.21 µg/dL (SD = 0.09) at time 2, and 0.18 µg/dL (SD = 0.08) at time 3. Delinquent peer exposure and post-traumatic stress symptoms were negatively associated with blunted stress responses, while greater depressive symptoms were positively associated with blunted stress responses. Black youth displayed distinct physiological stress reactivity patterns. Interventions are needed to assist youth in coping with stress while transforming the upstream factors that give rise to adverse community conditions.

Goal Orientation and Adolescent Social Competence: Ubuntu as a Mediator Among Black American Adolescents.

Social competence, which is the ability to demonstrate socio-emotional behavior skills, is crucial during adolescence with far-reaching implications across the lifespan. However, social competence development among youth is greatly influenced by social inequities, which places many Black American youth at a disadvantage due to the disproportionate burden on youth development in resource-constrained environments. Responsively, we sought to determine whether Afrocentric cultural norms (i.e., Ubuntu) and goal orientation contribute to the resilience of Black youth in developing social competence while controlling for social positions (i.e., social class and gender). For this study, we used the dataset of black boys and girls (average age of 14.68) from the Templeton Flourishing Children Project. Linear regression analysis followed by mediation analysis was conducted to identify the factors associated with higher degrees of social competence. Significant study findings indicate that Black youth reporting higher goal-oriented mindsets reported higher social competence scores. Goal orientation and social competence were mediated by Ubuntu, with the model explaining 63% variance in social competence in Black youth. The findings suggest prevention efforts that provide socialization centered around Afrocentric cultural norms may provide valuable means of bolstering social competence development in Black youth living in resource-constrained communities.
