Description
Accumulating evidence implicates exposure to adverse childhood experiences in the development of hypocortisolism in the long-term, and researchers are increasingly examining individual-level mechanisms that may underlie, exacerbate or attenuate this relation among at-risk populations. The current study takes a developmentally and theoretically informed approach to examining episodic childhood stressors, inherent and voluntary self-regulation, and physiological reactivity among a longitudinal sample of youth who experienced parental divorce. Participants were drawn from a larger randomized controlled trial of a preventive intervention for children of divorce between the ages of 9 and 12. The current sample included 159 young adults (mean age = 25.5 years; 53% male; 94% Caucasian) who participated in six waves of data collection, including a 15-year follow-up study. Participants reported on exposure to negative life events (four times over a 9-month period) during childhood, and mothers rated child temperament. Six years later, youth reported on the use of active and avoidant coping strategies, and 15 years later, they participated in a standardized psychosocial stress task and provided salivary cortisol samples prior to and following the task. Path analyses within a structural equation framework revealed that a multiple mediation model best fit the data. It was found that children with better mother-rated self-regulation (i.e. low impulsivity, low negative emotionality, and high attentional focus) exhibited lower total cortisol output 15 years later. In addition, greater self-regulation in childhood predicted greater use of active coping in adolescence, whereas a greater number of negative life events predicted increased use of avoidant coping in adolescence. Finally, a greater number of negative events in childhood predicted marginally lower total cortisol output, and higher levels of active coping in adolescence were associated with greater total cortisol output in young adulthood. Findings suggest that children of divorce who exhibit better self-regulation evidence lower cortisol output during a standardized psychosocial stress task relative to those who have higher impulsivity, lower attentional focus, and/or higher negative emotionality. The conceptual significance of the current findings, including the lack of evidence for hypothesized relations, methodological issues that arose, and issues in need of future research are discussed.

Description
Descriptions of gray divorce often include consequences for young adult children who are increasingly being left to cope with their parents’ decision. Adult children of divorce may experience different stressors and reactions than younger children especially during holidays; moreover, their increased social awareness leaves their parental relationship vulnerable to rupture as a result of pressure to choose sides. Interventions for helping young adults cope with their parents’ break-up are rarely described, much less evaluated. An online delivery format would be especially well-suited given the possibility of in-home participation at any time of day with privacy assured and negligible cost. We thus developed and experimentally evaluated Transitions, a two week internet-based program organized around a classic stress inoculation framework. The goals of Transitions are to foster stress-coping skills and to improve parent-child relationships throughout the divorce process. Our study was restricted to young adult college students (N = 95) who had experienced parental separation or divorce within the past year, and who were not receiving psychological services elsewhere. Participants were screened and randomly assigned to experimental and delayed-treatment control conditions; a priori analyses indicated sufficient power to detect large effects. During the first week of Transitions, participants received psychoeducation, training in progressive muscle relaxation, and a cognitive restructuring curriculum derived from Ellis and Beck. The second week began with a review and then introduced mindfulness meditation and communication skills. Practice sessions were embedded throughout the curriculum and simulations were specific to experiences of parental divorce. Videos of young college graduates sharing personal stories about their parents’ divorce were streamed between each module. Comprehension of the content presented in Transitions was monitored and coded for partial or full completion of the program. Outcome measures were keyed to the nature of the clinical problem and interventions deployed. A repeated-measures multivariate analysis of variance (RM-MANOVA) yielded a significant interaction. Univariate follow-up ANOVAs showed significant improvement relative to controls on stress but not on relationship variables. Neither moderator nor intent-to-treat analyses altered this outcome pattern. Future research will focus on refining the stress reduction components of Transitions and improving its impact on relationships with parents.
