Adrenocortical reactivity and social competence in seven year-olds

We examined temporal changes in salivary cortisol in response to a peer self-presentation task in a group of seven year-olds, some of whom scored high, average, and low on the Harter, 1983 Perceived Social Competence Scale. Salivary cortisol was measured pre-task, and 20 and 35 min post-task. We found a significant relation between individual differences in perceived social competence and salivary cortisol reactivity in response to the task. Children who perceived themselves as socially competent exhibited a significantly greater decrease in salivary cortisol from 20 to 35 min following the task compared with children who self-reported a relatively lower degree of social competence. We speculate on the meaning of salivary cortisol changes in childrens socio-emotional development.     

Associations Between Financial Strain and the Diurnal Salivary Cortisol Secretion of Long-term Unemployed Individuals

OBJECTIVE: The study investigated the associations between self-rated financial strain and overall diurnal salivary cortisol levels, as well as secretory patterns among long-term unemployed individuals. METHODS: Psychosocial and life-style variables were assessed by means of questionnaires among 85 participants (mean age 42+/-9 years; 56% females). Salivary cortisol was sampled on four occasions during a 24-hour period and data was analysed separately for men and women. RESULTS: Among females, high financial strain was related to higher overall cortisol levels, and to elevated levels in the evening. These associations did not reach significance among men. Multivariate analyses showed that evening levels of cortisol were positively associated with financial strain, but largely unrelated to life-style variables and psychological distress. CONCLUSIONS: The results suggest that high financial strain influences the diurnal cortisol secretion of unemployed individuals in terms of elevated cortisol levels in the evening. The mediating mechanisms are in need of further investigation.

Personal mastery predicts pain,stress, fatigue,and blood pressure in adults with rheumatoid arthritis

Among individuals with rheumatoid arthritis (RA), stress-associated disease flare can severely impact well-being. Psychological factors such as personal mastery may buffer an individual from the negative effects of those flares. We tested the hypothesis that a high sense of personal mastery would prospectively predict stress reactivity. Measures of pain, perceived stress, fatigue, and mean arterial pressure (MAP) were collected before, during, and after two interpersonal stressors conducted on 73 individuals with RA. Factor analysis of the personal mastery scale yielded two independent factors: a 5-item “fatalism” component and a 2-item “control” component. Individuals with high fatalism scores reported overall greater joint pain at baseline and those scoring high on control exhibited lower MAP, and reported less stress and fatigue at baseline. After controlling for baseline differences, those high in control exhibited greater MAP increase during stress, and less drop in pain when compared to those low in control. These results suggest that individuals high in control may be more susceptible to the effects of acute stress; however, the overall beneficial aspects of high control outweigh the acute negative effects. Personal mastery may play a role in the experience of pain, stress, and fatigue for people with RA.     

Mastery matters most: How mastery and positive relations link attachment avoidance and anxiety to negative emotions

Attachment avoidance and anxiety are associated with negative emotions. However, the mechanisms underlying these associations are not fully understood. We investigated environmental mastery and positive relations with others as two mechanisms behind the attachment–emotion link in a sample of 343 adults. As predicted, attachment avoidance and anxiety were related to greater fear, hostility, envy and depression through lower mastery. Contrary to our hypothesis, positive relations mediated only the attachment–depression link. In addition, by adopting a moderated mediation approach, we were able to show that mastery mattered most for individuals high on avoidance: The indirect effect of avoidance through lack of mastery on fear, hostility and depression (but not on envy) increased with higher avoidance scores. Contrary to our predictions, poor relationships did not matter more as sources of negative emotions as anxiety increased. These findings underscore that the emotional life of avoidantly attached individuals is especially jeopardised by poor mastery.     

Stressbew?ltigungsintervention am Arbeitsplatz

Background

Occupational stress is considered a major risk factor for a wide range of health outcomes. To examine long-term effects on perceived stress reactivity a randomized controlled trial [1?year after stress management intervention (SMI)] was implemented in a metal working plant.

Method

A total of 174 participants were randomly assigned to an intervention (IG) or a waiting control group (CG) and underwent a group-based program over 2 days, followed by 2-3?h booster sessions. The primary endpoint was perceived stress reactivity (Stress Reactivity Scale, SRS), while secondary endpoints were anxiety and depression (Hospital Anxiety and Depression Scale, HADS), salivary cortisol and alpha-amylase.

Results

SRS scores decreased in both groups. A two factor ANOVA proved greater reduction in the IG. For SRS, the effect size (Cohen??s d) after 1?year was d=0.416 in the IG and d=0.166 in the CG. Alpha-amylase as a measure of sympathetic nervous system activation decreased more strongly in the IG. Reduction of depression and anxiety was higher in the IG but did not reach statistical significance.

Conclusion

The conducted SMI is effective over a longer period in reducing perceived stress reactivity and sympathetic activation.     

Effect of pre- and postcompetition emotional state on salivary cortisol in top-ranking wrestlers

The purpose was three-fold: (1) to investigate the effect of baseline, precompetition, and postcompetition stress on salivary cortisol levels in top-ranking Brazilian wrestlers (N = 17) participating in a national competition; (2) to estimate correlations among three stress measures (perceived stress, salivary cortisol, and physiological stress reaction); and (3) to compare cortisol concentrations between losers and winners. Salivary cortisol was collected at baseline, pre-, and postcompetition. Physiological stress reaction and perceived stress scores were measured just before warm-up for the competition. Analysis showed a significant main effect for testing time. Correlations among the stress measures were not significant. Analysis of covariance between the winners (n = 10) and the losers (n = 7) was also not significant. Salivary cortisol concentrations increased after the intense exercise of competition. The wrestlers did not perceive any physiological effects.     

Stress reactivity in social anxiety disorder with and without comorbid depression

Previous research on neuroendocrine responding to a psychological stressor in individuals with Social Anxiety Disorder (SAD) has provided inconsistent results. A recent meta-analysis concluded that Major Depressive Disorder (MDD), which is frequently comorbid with SAD, is associated with blunted stress reactivity. It is, thus, possible that comorbidity status contributes to the inconsistent findings in the SAD literature. In this study, salivary cortisol responses to a psychological stressor were examined in three groups: healthy controls (CTL), SAD, and SAD with comorbid MDD (COM). The SAD group differed from the other two groups in their cortisol stress reactivity. It is important to note that analyses combining participants with SAD with and without comorbid MDD obscured findings of cortisol reactivity. In addition, the differences in cortisol reactivity cannot be accounted for by participants' affective responses to the stressor. The current findings indicate that individuals with SAD exhibit distinct stress-related cortisol responses depending on their comorbidity statuses.     

Cognitive performance and morning levels of salivary cortisol and alpha-amylase in children reporting high vs. low daily stress perception

The aim of the present study was to assess the effects of daily stress perception on cognitive performance and morning basal salivary cortisol and alpha-amylase levels in healthy children aged 9-12. Participants were classified by whether they had low daily perceived stress (LPS, n = 27) or a high daily perceived stress (HPS, n = 26) using the Children Daily Stress Inventory (CDSI). Salivary cortisol and alpha-amylase were measured at awakening and 30 minutes later. Cognitive performance was assessed using the Cognitive Drug Research assessment system. The HPS group exhibited significantly poorer scores on speed of memory (p < .05) and continuity of attention (p < .05) relative to the LPS group. The HPS group also showed significantly lower morning cortisol levels at awakening and at +30 minutes measures in comparison with the LPS group (p < .05), and mean morning cortisol levels were negatively correlated with speed of memory (p < .05) in the 53 participants. No significant differences were observed between both groups in alpha-amylase levels. These findings suggest that daily perceived stress in children may impoverish cognitive performance via its modulating effects on the HPA axis activity.

Emotion regulation and biological stress responding: associations with worry,rumination, and reappraisal

ABSTRACT

Individual differences in the habitual use of emotion regulation strategies may play a critical role in understanding psychological and biological stress reactivity and recovery in depression and anxiety. This study investigated the relation between the habitual use of different emotion regulation strategies and cortisol reactivity and recovery in healthy control individuals (CTL; n?=?33) and in individuals diagnosed with social anxiety disorder (SAD; n?=?41). The tendency to worry was associated with increased cortisol reactivity to a stressor across the full sample. Rumination was not associated with cortisol reactivity, despite its oft-reported similarities to worry. Worry and rumination, however, were associated with increased cortisol during recovery from the stressor. The only difference between CTL and SAD participants was observed for reappraisal. In the CTL but not in the SAD group, reappraisal predicted recovery, such that an increased tendency to reappraise was associated with greater cortisol recovery. These results suggest an important role of the habitual use of emotion regulation strategies in understanding biological stress reactivity and recovery.     

The influence of mastery‐avoidance goals on performance improvement

Two experiments focused on examining the influence of mastery‐avoidance goals on performance improvement, and more specifically, on mastery‐avoidance goals grounded in an intrapersonal standard. That is, herein, mastery‐avoidance goals entail striving to avoid doing worse than one has done before. Both experiments demonstrated that in a multiple‐trial context, mastery‐avoidance goals are deleterious for performance improvement relative to mastery‐approach, performance‐approach, and performance‐avoidance goals, and a no goal baseline. The findings were shown to be independent of participants' perceptions of goal difficulty, and were consistent not only across methodology but also across type of participant (undergraduates versus individuals in the workforce), and type and length of achievement task (a verbal skills task versus an ecologically valid managerial competencies exercise).

Parenting behaviors and learning of Singapore students: The mediational role of achievement goals

This study examined the mediational role of achievement goals between parental behaviors and learning outcomes. A sample of 1667 Singapore Secondary 3 students took the measures of parental involvement in learning, parental control, mastery approach and avoidance goals, performance approach and avoidance goals, as well as seven learning outcome variables in their math study. We conducted complex structural equation modeling analysis to take into account the hierarchical structure of the data and found a good fit for the hypothesized partial mediation model. More specifically, parental involvement in learning was associated with an adaptive learning profile (i.e., self-regulated engagement in learning activities, low anxiety, high perceived competence, and high achievement), partially or mainly through its positive relationship with mastery approach goals. Parental control predicted a maladaptive coping orientation (i.e., low persistence and high anxiety) and low achievement partially through its positive relationship with mastery and performance avoidance goals. The findings are discussed in the academic context of Singapore.     

Resilience and hypothalamic-pituitary-adrenal axis reactivity under acute stress in young men

The present study examined the relationship between resilience (measured using the Resilience Scale for Adults) and hypothalamic-pituitary-adrenal (HPA) axis reactivity. We examined the subjective and cortisol responses of 28 healthy young men to an acute stressor (public speech task). Eight saliva samples were collected in order to obtain the response curve (anticipation, reactivity, recuperation) for each subject. ANOVA indicated that highly resilient individuals tended to display less mood deterioration than less resilient individuals (marginal p(time x group interaction) = 0.075). They also revealed that the former tended to secrete less cortisol overall than the latter during the experiment (marginal p(main group effect) = 0.087) but this effect was not uniform across time (p(time x group interaction) = 0.029). Additional analyses performed to identify the source of this interaction revealed that resilience moderates cortisol secretion in anticipation of the stressor (i.e. highly resilient individuals secreted less cortisol than less resilient ones, p = 0.05) but that it is not conductive to lower HPA reactivity amidst stress (i.e. there was no difference between groups in the increase in cortisol secretion from baseline to peak). The recovery slopes were likewise not statistically different. The implications of these findings regarding health are discussed.     

Gender,attachment, and relationship duration on cardiovascular reactivity to stress in a laboratory study of dating couples

Stress related to relationship events has been a strong predictor of cardiovascular reactivity. This four‐phase laboratory study used a multiple‐nested design to examine variations in diastolic blood pressure (DBP) and rate‐pressure product (RPP: pulse rate [PR] × systolic blood pressure [SBP]) as a function of stress appraisal using 33 college‐aged dating couples. Individual participants filled out questionnaires designed to assess the length of their relationships (couple‐level factor), gender and attachment styles (individual‐level factors); watched a film clip depicting relationship distress; discussed relationship problems; then received instruction for relaxation. Individuals’ self‐reported stress and negative affect levels (experimental phase‐level factors), DBP, SBP, and PR were also measured at each study phase. Hierarchical linear modeling analyses revealed that relationships with longer duration were associated with higher levels of DBP and RPP as perceived stress levels increased. Also, as perceived stress levels increased, men or individuals high in the anxiety dimension of attachment showed higher DBP and RPP reactivity, whereas individuals high in the avoidance dimension of attachment showed lower RPP reactivity. As the negative affect level increased, individuals high in the avoidance dimension of attachment showed lower RPP reactivity. Findings imply that under relationship stress, individuals high in avoidance or anxiety dimensions of attachment may be vulnerable to a range of physical symptoms, such as cardiovascular disease or hypertension.     

Salivary cortisol concentrations, stress and quality of life in women with endometriosis and chronic pelvic pain

The objective of this study was to evaluate the perceived stress index, quality of life, and hypothalamus-pituitary-adrenal axis activity in women with endometriosis and chronic pelvic pain. For the study, 93 women with endometriosis and 82 healthy women volunteered. The visual analogue scale (VAS) (0=no pain; 10=severe pain) was used to determine pain intensity; the perceived stress questionnaire (PSQ) defined stress index, and the health-related quality-of-life (HRQOL)-SF-36 questionnaire was used to evaluate quality of life. Salivary cortisol was measured at 0800, 1600, and 2000 h and the awakening cortisol response was assessed to evaluate the hypothalamus-pituitary-adrenal axis activity. The results show that women with endometriosis and chronic pelvic pain of moderate intensity (4.1+/-0.58, mean+/-SEM) have higher levels of perceived stress (0.55+/-0.01 versus 0.42+/-0.01, p<0.05), a poorer quality of life expressed as lower scores for all items of the inventory and hypocortisolism. Lower levels of salivary cortisol were observed in all three samples collected, as well as in the awakening cortisol response, for women with endometriosis (0.19+/-0.09 microg/dl) when compared with controls (0.78+/-0.08 microg/dl, p<0.05 l), and it was independent of pain intensity and Mental health (MH) scores in SF-36. We concluded that women with endometriosis and chronic pelvic pain show low concentrations of salivary cortisol and a high level of perceived stress, associated with a poor quality of life. Whether the hypocortisolism was an adaptive response to the aversive symptoms of the disorder or a feature related to the etiology of endometriosis remains to be elucidated.     

Effects of a prevention program for divorced families on youth cortisol reactivity 15 years later

Objective: We examined whether an empirically based, randomised controlled trial of a preventive intervention for divorced mothers and children had a long-term impact on offspring cortisol regulation.

Design: Divorced mothers and children (age 9–12) were randomly assigned to a literature control condition or the 11-week New Beginnings Program, a family-focused group preventive intervention for mothers and children in newly divorced families.

Main Outcome Measures: Fifteen years after the trial, offspring salivary cortisol (n = 161) was measured before and after a social stress task.

Results: Multilevel mixed models were used to predict cortisol from internalizing symptoms, externalizing symptoms, group assignment and potential moderators of intervention effects. Across the sample, higher externalizing symptoms were associated with lower cortisol reactivity. There was a significant group-by-age interaction such that older offspring in the control group had higher reactivity relative to the intervention group, and younger offspring in the control group exhibited a decline across the task relative to younger offspring in the intervention group.

Conclusions: Preventive interventions for youth from divorced families may have a long-term impact on cortisol reactivity to stress. Results highlight the importance of examining moderators of program effects.

Persistent Heightened Cortisol Awakening Response and Adolescent Internalizing Symptoms: A 3-year Longitudinal Community Study

An atypical Cortisol Awakening Response (CAR) has been related to adult anxiety and depression, but little is known about the association between long-term atypical CAR and adolescent anxiety and depression. This study aimed to longitudinally identify subgroups of adolescents with distinct levels of CAR (i.e., adolescents with and without persistent atypical CAR) and to examine their development of anxiety and depressive symptoms over 3 successive years. A community sample of 184 Dutch adolescents (M _age?=?14.99 at T₁, 57 % boys) completed annual salivary cortisol assessments at home at time of awakening, and 30 and 60 min post-awakening (i.e., CAR) for 3 successive years. Adolescents also reported annually on their anxiety and depressive disorder symptoms. Latent Class Growth Analysis suggested two subgroups of adolescents with respect to CAR: a “low” group with stable low levels of AUC_g (Area Under the Curve with respect to the ground) over time and a “high” group with high and increasing levels of AUC_g over time. Controlling for sex, the high and low CAR groups significantly differed in depressive symptoms only, but none of the anxiety disorder symptoms. More specifically, adolescents in the high CAR group showed significantly higher mean levels of depressive symptoms over time compared to adolescents in the low CAR group. These results suggest that persistent heightened CAR is a more consistent, yet modest, correlate of adolescent depressive symptoms than anxiety disorder symptoms.
