Abstract
OBJECTIVE: This study aimed to (1) examine coping strategies and their relationship with demographics, perceived stress, and hair cortisol; and (2) explore whether coping partially mediated the relationship between perceived stress and hair cortisol. METHODS: Baseline data from 191 socioeconomically marginalized parents enrolled in two community-based clinical trials were used. The IBM SPSS Statistics Version 27 and Mplus Version 8 were used for data analyses. RESULTS: Parents' engagement in various coping strategies differed by age, ethnicity, race, marital status, education level, and number of children living in the household. Parents' use of problem-focused (instrumental support, planning), emotion-focused (venting, self-blame), and avoidant coping (self-distraction, denial, behavioral disengagement) increased from having low to moderate stress. However, when perceived stress increased from moderate to high, their use of emotion-focused and avoidant coping increased significantly, but problem-focused coping did not. Emotion-focused coping lowered the influence of perceived stress on hair cortisol, while avoidant coping increased the relationship between perceived stress and hair cortisol. CONCLUSIONS: Although needing future investigation with longitudinal studies, the results suggest the need of promoting adaptive emotion-focused coping (emotional support, venting, and humor) to help socioeconomically marginalized parents manage their appraised overwhelming and uncontrollable stressors of food, house, and income insecurity.
