Hair cortisol and cognitive performance in working age adults

It has been hypothesized that prolonged exposure to high cortisol levels results in cognitive impairment. However, previous research into the relationship between cortisol and cognition has produced mixed results, most likely due to difficulties achieving valid estimates of long-term cortisol exposure based on salivary or plasma cortisol assessments at a single time point. Furthermore, there has been little research on the cognitive effects of long-term cortisol exposure in working-age adults. In the present study, hair samples were collected from 246 nurses (89.8% female) aged from 21 to 62 (M = 42.0, SD = 11.2). Hair cortisol concentrations (HCC) in the proximal 3-cm hair segment were analyzed providing an estimate of integrated cortisol secretion over the 3 month-period prior to hair sampling. Cognition was measured using a battery of 15 neuropsychological tests, measuring core dimensions of memory, inductive reasoning, processing speed, crystalized intelligence and major aspects of executive functioning. HCC was not significantly related to any of the cognitive abilities measured, either before or after controlling for potential moderators such as age, sex, education, health, well-being, work ability and burnout. Tests for nonlinear relationships also yielded non-significant results. Thus, despite the study being well powered, long term cortisol exposure did not appear to be related to cognitive performance in this sample of working-age adults, suggesting that long term cortisol exposure may be less relevant to cognition in younger and middle-aged adults than was previously thought

Mental health of working parents during the COVID-19 pandemic: can resilience buffer the impact of psychosocial work stress on depressive symptoms?

Abstract Background The COVID-19 pandemic has confronted working parents with an accumulation of stressors regarding changes in work, family, and social life, putting their mental health at risk. Stressors include altered working conditions such as working from home or changes in working hours as well as the difficulty to reconcile work and childcare due to the closure of childcare facilities. The present study examined the relationship of psychosocial work stress (i.e., work-privacy conflict and effort-reward imbalance at work) and depressive symptoms in working parents and whether this association was moderated by individual resilience. Methods Data of the present study (n = 452) were collected in Germany between May and June 2020 as part of the DREAMCORONA study. A subsample of working mothers (n = 191) and fathers (n = 261) completed the subscale for work-privacy conflict (WPC) of the Copenhagen Psychosocial Questionnaire, the Effort-Reward Imbalance (ERI) Questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), and the Edinburgh Postnatal Depression Scale (EPDS). Multiple linear regression analyses including moderation were performed, controlling for gender, working hours per week, and a lifetime history of depression as potential confounders. Results Both WPC (β = 0.336, p < .001) and ERI (β = 0.254, p < .001) were significantly associated with depressive symptoms. Resilience moderated the relationship between ERI and depressive symptoms (β = − 0.101, p = .018), indicating that higher resilience weakened the relationship. However, this effect was not found regarding the relationship between WPC and depressive symptoms (β = 0.055, p = .167). Conclusions The results highlight the need for measures to reduce psychosocial work stressors such as WPC and ERI during the COVID-19 pandemic on the one hand and to promote resilience on the other hand. The findings partially support the potential protective role of resilience buffering the association between psychosocial stress and mental health in working parents. Longitudinal studies are needed to confirm this effect

Early Abusive Relationships–Influence of Different Maltreatment Types on Postpartum Psychopathology and Mother-Infant Bonding in a Clinical Sample

Postpartum psychopathology is a well-documented risk factor for impaired mother-infant bonding and thus child development. Increasingly, the focus of research in this area lies on maternal adverse childhood experiences that mothers bring into the relationship with their own baby, especially regarding the possible intergenerational transmission of traumatic experiences. Several studies showed that there is no direct link between child maltreatment and mother-infant bonding as one part of mother-child relationship, but that this link is mediated by postpartum psychopathology. To date, few studies examined differential effects between sexual, physical, and emotional abuse, and physical and emotional neglect, especially in a clinical sample. The aim of this study is to investigate whether the relationship between child maltreatment, psychopathology, and mother-infant bonding can be found for different forms of child maltreatment in patients of a mother-baby unit. Our sample consisted of 330 mothers of a mother-baby-unit in a psychosomatic clinic, who filled out self-report measures at time of admission. Mothers reported on maternal child maltreatment history with the Childhood Trauma Questionnaire, on current psychopathology with the Brief Symptom Inventory, and on mother-infant bonding with the Postpartum Bonding Questionnaire. Mediation analyses were performed with psychopathology as mediator, child maltreatment history as independent, and mother-infant bonding as dependent variable. There was no total effect of child maltreatment on mother-infant bonding. However, there were significant indirect effects of child maltreatment in general (ab = 0.09) and of the various forms of child maltreatment on mother-infant bonding via psychopathology (0.16 ≤ ab ≤ 0.34). The strongest effect was found for emotional abuse. After controlling for psychopathology, the direct effect of physical abuse on mother-infant bonding presented as a negative significant effect. This indicates that the more severe the physical abuse experienced, the better the self-reported bonding. A similar, but non-significant trend was found for sexual abuse. Our findings highlight the importance of assessing neglect forms of child maltreatment as well as abuse in women during the perinatal period. It further supports initial findings that different forms of child maltreatment can have differential effects on mother-infant bonding as one aspect of the mother-child relationship. Further research should include observational data to compare with self-report measures

Cognitive functioning in posttraumatic stress disorder before and after cognitive-behavioral therapy

Although substantial evidence suggests altered executive functioning and autobiographical memory in posttraumatic stress disorder (PTSD), the clinical significance of these findings remains unclear. Here, we investigated the effects of cognitive-behavioral therapy (CBT) on different aspects of cognitive functioning (working memory, interference susceptibility, conflict adaptation, autobiographical memory) in PTSD patients in a pre-post control group design with a nested cross-sectional element. Cross-sectional analyses at baseline were conducted on 58 PTSD patients, 39 traumatized (TC), and 45 non-traumatized controls (NTC). Intervention effects were investigated before and after 25 CBT sessions in 25 PTSD and 34 untreated NTC individuals assessed in parallel. At baseline, PTSD patients showed higher conflict adaptation than the NTC group and less autobiographical memory specificity than both control groups, suggesting particularly the latter to be a correlate of PTSD. No consistent evidence for treatment-induced improvements in cognitive functioning emerged on the group level or from associations between intra-individual clinical and cognitive changes. Analyses on the role of cognitive functioning on subsequent treatment effects revealed a predictive effect of backward digit span on CBT-induced reductions of depressiveness, but no other significant effects. Our findings highlight the need for further research to identify more relevant predictors of differential treatment response
