Daily mood reactivity to stress during childhood predicts internalizing problems three years later
Bai S , Robles TF , Reynolds BM , Repetti RL . J Abnorm Child Psychol 2020 48 (8) 1063-1075 The mental health toll of common school problems that many children encounter every day is not well understood. This study examined individual differences in mood reactivity to naturally occurring school problems using daily diaries, and assessed their prospective associations with youth mental health, three years later. At baseline, 47 children ages 8 to 13 years described common problems at school and mood on a daily basis, for 8 weeks. Thirty-three youth returned for follow-up three years later at ages 11 to 17 years. Children and parents also completed one-time questionnaires about youth mental health at baseline and follow-up. There were individual differences in the within-person associations between school problems and same-day and next-day mood. A greater tendency to react to school problems with more negative mood or less positive mood on the same day predicted more parent-rated internalizing and externalizing problems and child ratings of depression symptoms three years later, relative to baseline levels of symptoms. Daily diaries can help to identify specific targets of psychosocial interventions in real world settings. |
Chronic stress exposure and daily stress appraisals relate to biological aging marker p16(INK4a)
Rentscher KE , Carroll JE , Repetti RL , Cole SW , Reynolds BM , Robles TF . Psychoneuroendocrinology 2018 102 139-148 Previous research has linked exposure to adverse social conditions with DNA damage and accelerated telomere shortening, raising the possibility that chronic stress may impact biological aging pathways, ultimately increasing risk for age-related diseases. Less clear, however, is whether these stress-related effects extend to additional hallmarks of biological aging, including cellular senescence, a stable state of cell cycle arrest. The present study aimed to investigate associations between psychosocial stress and two markers of cellular aging-leukocyte telomere length (LTL) and cellular senescence signal p16(INK4a). Seventy-three adults (Mage = 43.0, SD = 7.2; 55% female) with children between 8-13 years of age completed interview-based and questionnaire measures of their exposures to and experiences of stress, as well as daily reports of stress appraisals over an 8-week diary period. Blood samples were used to assess markers of cellular aging: LTL and gene expression of senescent cell signal p16(INK4a) (CDKN2A). Random effects models covarying for age, sex, ethnicity/race, and BMI revealed that participants with greater chronic stress exposure over the previous 6 months (b = 0.011, p = .04), perceived stress (b = 0.020, p < .001), and accumulated daily stress appraisals over the 8-week period (b = 0.013, p = .02) showed increased p16(INK4a). No significant associations with LTL were found. These findings extend previous work on the impact of stress on biological aging by linking chronic stress exposure and daily stressful experiences to an accumulation of senescent cells. Findings also support the hypothesis that chronic stress is associated with accelerated aging by inducing cellular senescence, a common correlate of age-related diseases. |
Interparental conflict and child HPA-axis responses to acute stress: Insights using intensive repeated measures
Kuhlman KR , Repetti RL , Reynolds BM , Robles TF . J Fam Psychol 2018 32 (6) 773-782 Interparental conflict is a common source of psychosocial stress in the lives of children. The purpose of this study was to examine the association between recent interparental conflict and one component of the physiological stress response system, the hypothalamic-pituitary-adrenal (HPA)-axis. Parents of 42 children (ages 8-13 years) completed daily diaries of interparental conflict for 8 weeks. At the end of the 8 weeks, youth participated in the Trier Social Stress Test for Children (TSST-C) while providing 2 pre- and 4 poststress salivary cortisol samples. Youth whose fathers reported a pattern of increasing interparental conflict over the past 8 weeks demonstrated an exaggerated HPA-axis response to acute stress. Mother-reported interparental conflict was not associated with children's HPA-axis responses without accounting for fathers' reports. When accounting for fathers' reports, the offspring of mothers reporting higher average daily interparental conflict demonstrated an attenuated HPA-axis response to the stressor. By estimating both average exposure and recent patterns of change in exposure to conflict, we address the circumstances that may prompt attenuation versus sensitization of the HPA-axis in the context of interparental conflict. We conclude that the HPA-axis is sensitive to proximal increases in interparental conflict which may be one pathway through which stress affects health across development, and that incorporating father's reports is important to understanding the role of the family environment in stress responses. This study further demonstrates the value of using intensive repeated measures and multiple reporters to characterize children's psychosocial environment. |
Children's diurnal cortisol responses to negative events at school and home
Bai S , Robles TF , Reynolds BM , Repetti RL . Psychoneuroendocrinology 2017 83 150-158 This study examined the within-and between-person associations between daily negative events - peer problems, academic problems and interparental conflict - and diurnal cortisol in school-age children. Salivary cortisol levels were assessed four times per day (at wakeup, 30min later, just before dinner and at bedtime) on eight days in 47 youths ages 8-13 years old (60% female; M age=11.28, SD=1.50). The relative contributions of within- and between-person variances in each stressor were estimated in models predicting same-day diurnal cortisol slope, same-day bedtime cortisol, and next morning wakeup cortisol. Children who reported more peer problems on average showed flatter slopes of cortisol decline from wakeup to bedtime. However, children secreted more cortisol at wakeup following days when they had reported more peer or academic problems than usual. Interparental conflict was not significantly associated with diurnal cortisol. Findings from this study extend our understanding of short-term cortisol responses to naturally occurring problems in daily life, and help to differentiate these daily processes from the cumulative effects of chronic stress. |
