title: Mental health and diurnal salivary cortisol patterns among African American and European American female dementia family caregivers.
abstract: Using a sociocultural stress and coping model, this pilot study examines the influence of depressive symptoms and stress on diurnal salivary cortisol patterns among African American (N=30) and European American (N=24) female dementia caregivers and noncaregivers (African American, N=48; European American, N=15). Caregiving participants completed the Center for Epidemiological Studies Depression Scale (CES-D), Perceived Stress Scale (PSS), and Stress-Related Growth Scale (SRGS) as respective measures of depressive symptoms, stress, and stress resilience. Participants also collected five saliva samples daily for two consecutive days. African American caregivers scored significantly higher than European American caregivers on the SRGS, but they did not differ on the PSS and CES-D scales. Regression analyses with age, ethnicity, caregiving status, and depressive symptoms as predictors, and cortisol slope as criterion, showed that only age and ethnicity predicted cortisol slope. African Americans had flatter slopes than the European Americans sampled, regardless of caregiving status. Findings highlight the role of cultural beliefs and of ethnicity in explaining cortisol function.
