Abstrakt: Though considerable work supports the Dimensional Model of Adversity and Psychopathology, prior research has not tested whether the dimensions-threat (e.g., abuse) and deprivation (e.g., neglect)-are uniquely related to salivary trait indicators of hypothalamic pituitary adrenal (HPA) axis activity. We examined the unique and interactive effects of threat and deprivation on latent trait cortisol (LTC)-and whether these effects were modified by co-occurring adversities. Emerging adults (n = 90; M age  = 19.36 years; 99.88% cisgender women) provided salivary cortisol samples four times a day (waking, 30 min and 45 min postwaking, bedtime) over three 3-day measurement waves over 13 weeks. Contextual life stress interviews assessed early adversity. Though the effects varied according to the conceptualization of early adversity, overall, threat-but not deprivation, nor other co-occurring adversities-was uniquely associated with the across-wave LTC. Specifically, the incidence and frequency of threat were each negatively related to the across-wave LTC. Threat severity was also associated with the across-wave LTC, but only among those with no deprivation. Finally, the effects of threat were modified by other co-occurring adversities. Findings suggest that threat has unique implications for individual differences in HPA axis activity among emerging adults, and that co-occurring adversities modify such effects.
