Background: Disrupted sleep quality is one of the proposed mechanisms through which chronic stress may lead to depression. However, there exist significant individual differences in sleep reactivity, which is the extent to which one experiences sleep disturbances in response to stress.Purpose: The aim of the current study was to investigate whether low high-frequency heart rate variability (HRV), as a psychophysiological marker of poor emotional and physiological arousal regulation, predicts stress-related sleep disturbances associated with greater risk of depression symptoms.Methods: Using a chronic caregiving stress model, 125 mothers of adolescents with developmental disorders and 97 mothers of typically developing adolescents had their resting HRV and HRV reactivity recorded and completed a measure of depressive symptoms, as well as a 7 day sleep diary to assess their sleep quality. A moderated mediation model tested whether sleep quality mediated the association between chronic stress exposure and depressive symptoms and whether HRV moderated this mediation.Results: After controlling for participant age, body mass index, ethnicity, socioeconomic status, and employment status, poor sleep quality mediated the association between chronic stress and depressive symptoms. Resting HRV moderated this indirect effect such that individuals with lower HRV were more likely to report poorer sleep quality in the context of chronic stressor exposure, which, in turn, was related to greater depressive symptoms.Conclusions: Lower HRV, a potential biomarker of increased sleep reactivity to stress, is associated with greater vulnerability to stress-related sleep disturbances, which, in turn, increases the risk for elevated depressive symptoms in response to chronic stress.

Close relationships are an important social context in which emotional experiences, regulation, and coregulation unfold. This interpersonal emotion regulation process is likely intertwined with the self-regulatory capacities and social skills of each individual dyad member. This study aimed to examine whether respiratory sinus arrhythmia (RSA), a physiological marker related to self-regulation, moderates the impact of rumination, a maladaptive emotion regulation strategy, on couples' conflict. A dyadic, longitudinal design examined the association among RSA, rumination, and couples' conflict in a sample of 83 cohabiting romantic partners raising young children. At baseline, rumination and RSA from each romantic partner were assessed. Couples' conflict was reported at 3 time points over the following 12 months. Actor-partner interdependence modeling examined the mutual contributions of each couple member's rumination to couples' conflict, as well as the moderating impact of RSA. Results indicated that rumination from both members of the dyad were independently associated with couples' conflict across the 12-month period. Furthermore, RSA moderated the association between one's partner's rumination and couples' conflict, such that high actor RSA attenuated the positive association between partner's rumination and couples' conflict. The findings highlight the interdependent nature of emotion regulation within close relationships, and the impact of RSA on interpersonal emotion regulation processes.

Respiratory sinus arrhythmia (RSA) is a biomarker of cardiac vagal tone that has been linked to social functioning. Recent studies suggest that RSA moderates the impact of interpersonal processes on psychosocial adjustment. The goal of this study was to assess whether RSA would moderate the association between dyadic coping (DC) and depressive symptoms. Eighty cohabiting couples raising preschool children completed the Dyadic Coping Inventory, the Center for Epidemiological Study-Depression scale and had their RSA assessed during a laboratory session. Couples completed follow-up assessments of depressive symptoms 6 and 12 months later. Data were analyzed using an Actor-Partner Interdependence Model. Results indicated that RSA moderated the actor effect of negative DC on depression in men, such that men with lower RSA had a stronger association between their own ratings of negative DC within the couple relationship and their own depressive symptoms, compared to their counterparts with higher RSA. RSA also moderated the partner effect of delegated DC on depressive symptoms. Among men with higher RSA, there was a significant negative association between their partner's ratings of delegated DC within the couple relationship and the men's depressive symptoms, whereas partner-rated delegated DC was unrelated to depressive symptoms among men with lower RSA. These results suggest that men with higher RSA may possess social skills and abilities that attenuate the association between stressful marital interactions and negative mood. [ABSTRACT FROM AUTHOR]

Abstract: Sleep is a basic biological process supporting emotion regulation. The emotion regulation function of sleep may be particularly important in the context of chronic stress. To better understand how chronic stress and sleep interact to predict mood, 66 parents of children with autism completed daily diaries assessing parenting stress, negative mood, and sleep quality for 6 consecutive days. Hierarchical linear modelling revealed that daily negative mood was predicted by between‐person differences in parenting stress and between‐person differences in sleep efficiency. Further, between‐person differences in sleep efficiency and within‐person differences in sleep satisfaction moderated the impact of stress on mood. These data suggest that sleep disturbances may exacerbate the association between stress and mood in the context of chronic parenting stress. Further, high parenting stress appears to heighten the impact of transient sleep disturbances on mood. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Marital quality impacts inflammatory processes. Dyadic coping, a spousal support process in which members of a couple work together to cope with the stressors that 1 or both partners are facing, is associated with higher marital satisfaction and reduced psychological distress. The goal of the present study was to evaluate whether dyadic coping is also related to systemic inflammation among individuals facing chronic parenting stress. Method: Forty-four parents of children with an autism spectrum disorder completed self-report questionnaires on dyadic coping, marital satisfaction, perceived social support, and caregiving burden. They also provided a blood sample for C-reactive protein (CRP) analysis, a marker of systemic inflammation. Results: Higher positive dyadic coping was significantly associated with lower circulating CRP, while negative dyadic coping was unrelated to CRP. After adjusting for individual differences in marital satisfaction, perceived social support, and caregiving burden, positive dyadic coping became marginally associated with CRP. Conclusion: Positive dyadic coping is a specific interpersonal process that may modulate systemic inflammation among individuals exposed to chronic stress. [ABSTRACT FROM AUTHOR]

Emeryville, California's Fair Workweek Ordinance (FWO) aimed to reduce service workers' schedule unpredictability by requiring large retail and food service employers to provide advanced notice of schedules and to compensate workers for last-minute schedule changes. From ninety-six workers with young children (N = 78 in longitudinal analyses; 58 percent working in regulated businesses at baseline), this study gathered daily reports of work schedule unpredictability and worker and family well-being over three waves before and after FWO implementation. The FWO decreased working parents' schedule unpredictability and improved their well-being relative to those in similar jobs at unregulated establishments. The FWO also decreased parents' days worked while increasing hours per work day, leaving total hours roughly unchanged. Finally, parent well-being improved and declines in sleep difficulty were significant. [ABSTRACT FROM AUTHOR]
