Does high perceived stress over the past month alter cortisol reactivity to the Trier Social Stress Test?

Background: Theories highlight the important role of chronic stress in remodeling HPA-axis responsivity under stress. The Perceived Stress Scale (PSS) is one of the most widely used measures of enduring stress perceptions, and no previous studies have evaluated whether greater perceptions of stress on the PSS are associated with cortisol hypo- or hyperactivity responses to the Trier Social Stress Test (TSST).

Objective: To examine if high perceived stress over the past month, as measured by the PSS, alters cortisol and subjective acute stress reactivity to the TSST in healthy young adults.

Depressive and Anxious Symptoms, Experimentally Manipulated Acute Social-Evaluative Threat, and Cortisol Reactivity.

Objective: Exposure to social-evaluative threat (SET) can elicit greater physiological responses, including cortisol, compared to non-SET stressors. An individual's level of depressive and anxious symptoms predicts variability in cortisol responses to stressors, and other research suggests that these individual differences may predict vulnerability to social evaluation. The current study integrates both lines of research, testing if there are different relationships between depressive and/or anxious symptoms and cortisol reactivity in the presence or absence of SET.

Re-assessing the assessment of fears of positive and negative evaluation: Scale development and psychometric evaluation of the Bivalent Fear of Evaluation Scale (BFOES).

The bivalent fear of evaluation (BFOE) model of social anxiety divides fear of evaluation into two distinct valences: fear of positive evaluation (FPE) and fear of negative evaluation (FNE). However, there is evidence that the two most widely utilized and psychometrically supported measures of FNE and FPE contain items which are ambiguous with regard to valence of evaluative fear. To formally address this, the BFOE Scale (BFOES) was developed, by merging items from measures of FNE and FPE into a single scale with an integrated response format.

Conflicting patterns of cardiovascular reactivity, self-report, and behavior associated with social anxiety during a conversation with a close friend.

Social anxiety (SA) is characterized by anxious symptomology and fear during social situations, but recent work suggests that SA may not necessarily be associated with negative interpersonal and intrapersonal outcomes in support contexts. The current research investigates the discrepancies between self-perceptions, behavior, and physiological responses associated with SA in social support conversations with close friends. Specifically, we examined the associations between SA and positive and negative affect, perceptions of demands and resources, and responsiveness.

The role of social-evaluative threat for cortisol profiles in response to psychosocial stress: A person-centered approach.

Heterogeneity in individuals' physiological stress responses is central to theories linking stress with vulnerability to disease. Although multiple cortisol profiles have been reported in response to acute psychological stress, most prior work focuses on a single, average pattern and relative deviations from it, such as greater or lesser response peaks or reactivity. The present aims were to identify cortisol stress response trajectory classes using a data-driven approach and test whether social-evaluative threat (SET), a reliable elicitor of cortisol, predicted a greater likelihood of membership in the more reactive profiles.

Gender roles are related to cortisol habituation to repeated social evaluative stressors in adults: secondary analyses from a randomized controlled trial.

Masculine and feminine gender roles influence stressor appraisals and coping in everyday life, but their effect on stress response systems like the hypothalamic-pituitary-adrenocortical axis is unclear. Accordingly, the present study tested the association between gender roles and cortisol responses to repeated stress as part of secondary analyses of data from a randomized controlled trial examining the effects of stress management interventions on cortisol habituation. Participants (N = 86; 72% female) completed a baseline survey assessing gender role endorsement using the Bem Sex Role Inventory, from which 4 groups were derived: masculine ( = 20), feminine ( = 20), androgynous (high masculinity, high femininity;  = 22), and undifferentiated (low masculinity, low femininity;  = 24).

Standardized stress reduction interventions and blood pressure habituation: Secondary results from a randomized controlled trial.

Unlabelled: Meta-analyses suggest a small association between cardiovascular responses to acute stressors and cardiovascular disease, but a recent review suggests that this effect may be underestimated due to insufficient consideration of individual differences in habituation to repeated stressors.

Objective: The present article reports new analyses of a published randomized controlled trial comparing the effects of mindfulness-based stress reduction (MBSR), cognitive behavioral therapy (CBT), and a passive control condition on blood pressure habituation-a secondary outcome. Psychological mediators of intervention effects were examined.

Childhood adversity and cortisol habituation to repeated stress in adulthood.

Background: Childhood adversity is a robust predictor of poor health outcomes in adulthood and hypothalamic-pituitary-adrenocortical (HPA) axis dysfunction may be a key mechanism explaining this association. However, little is known about the influence childhood adversity may exhibit on adult HPA axis habituation (i.e.

Daily stressors and diurnal cortisol among sexual and gender minority young adults.

Objective: Minority stress may contribute to poor health by dysregulating stress response systems, including diurnal cortisol rhythms. However, few studies have examined the association between sexual and gender minority stress and diurnal cortisol in lesbian, gay, bisexual, and transgender (LGBT) individuals. The current investigation tested whether the daily experience of minority stressors is uniquely related to diurnal cortisol above and beyond general stressors.

When enhanced awareness threatens: Interactive effects of domain-specific awareness and acceptance manipulations on cardiovascular indices of challenge and threat.

Mindfulness includes acceptance and awareness subcomponents, and emerging theories imply that cultivating both acceptance and awareness may benefit health by diminishing stress reactivity. Yet, no prior work has examined the effects of mindful acceptance and awareness on cardiovascular markers of threat and challenge-cardiac output and total peripheral resistance-despite the unique insights these indices yield into stress-related evaluations and motivation. The current research integrates Monitor and Acceptance Theory with the Biopsychosocial Model of Challenge and Threat to elucidate how an awareness manipulation and a brief acceptance training are associated with cardiovascular stress responses underlying states of challenge and threat.

Corroborative evidence for an association between initial hypothalamic-pituitary-adrenocortical axis reactivity and subsequent habituation in humans.

Background: The extant literature predicts that initial hypothalamic-pituitary-adrenocortical (HPA) axis response magnitude and subsequent habituation are associated with health, such that both heightened stress reactivity and non-habituation to repeated stressors are associated with disease. Yet, despite evidence for an association between initial HPA axis reactivity and subsequent habituation, the extant literature often considers health implications of these stress response patterns independently or make interpretations based on an initial response alone. This may be because past tests of the association between reactivity and habituation were subject to statistical bias (e.

Is Receiving Social Support Costly for Those Higher in Subjective Socioeconomic Status?

Background: Although social support is generally thought to have positive consequences, this is not always the case. Receiving social support may threaten independence, which research has shown is more highly valued among those higher in socioeconomic status. As a result, support may be less strongly associated with positive outcomes for those higher in socioeconomic status (SES).

Cognitive behavioral therapy, mindfulness, and cortisol habituation: A randomized controlled trial.

Background: Hypothalamic-pituitary-adrenocortical (HPA) axis dysregulation is associated with disease and may be indexed by poor cortisol habituation (i.e., a failure to show decreased responding with repeated stressor exposure).

Testosterone to cortisol ratio and aggression toward one's partner: Evidence for moderation by provocation.

Background: Consistent with the dual-hormone hypothesis, the combination of high testosterone levels and low cortisol levels has been linked to increased dominant and aggressive behaviors. However, recent research indicates that this association is weaker or even reversed following provocation. It is also unclear whether the association between testosterone/cortisol and aggression is similar for men and women and for those with and without attention-deficit/hyperactivity disorder (ADHD).

When Family Matters Most: A Test of the Association Between Sexual Minority Identity Disclosure Context and Diurnal Cortisol in Sexual Minority Young Adults.

Objective: Revealing one's sexual identity to others is a complex process marked by a shift in the types of stressors faced by sexual minority young adults. Such stressors influence the secretion of health-relevant hormones, including cortisol, yet how dimensions of disclosure (i.e.

Social-evaluative threat, cognitive load, and the cortisol and cardiovascular stress response.

Background: Current evidence suggests that exposure to social-evaluative threat (SET) can elicit a physiological stress response, especially cortisol, which is an important regulatory hormone. However, an alternative explanation of these findings is that social-evaluative laboratory tasks are more difficult, or confer greater cognitive load, than non-evaluative tasks. Thus, the current experiment tested whether social-evaluative threat, rather than cognitive load, is truly an "active ingredient" in eliciting a cortisol response to stressors.

Recovery from stress: an experimental examination of focused attention meditation in novices.

Identifying strategies that aid in recovery from stress may benefit cardiovascular health. Ninety-nine undergraduate meditation novices were randomly assigned to meditate, listen to an audio book, or sit quietly after a standardized stressor. During recovery, meditators' heart rate variability and skin conductance levels returned to baseline, whereas only heart rate variability returned to baseline for the audio book and control groups.

Education Is Associated with the Magnitude of Cortisol Responses to Psychosocial Stress in College Students.

Purpose: Researchers benefit from controlling for individual differences that systematically account for variance in acute cortisol responses (e.g., sex).

Trait mindfulness predicts the presence but not the magnitude of cortisol responses to acute stress.

Background: Mindfulness, or the practice of observing present moment experiences with acceptance, is thought to improve health at least partially by limiting hypothalamic-pituitary-adrenal (HPA) axis over-responsiveness during episodes of acute stress. However, models of allostatic load suggest that HPA axis under-responsiveness can also be detrimental to health, and the relationship between mindfulness and cortisol under-responsiveness has yet to be examined. The present study therefore aimed to address this knowledge gap, and to revisit the relationship between mindfulness and acute cortisol response magnitude while excluding (or statistically controlling for) individuals displaying HPA axis under-responsiveness.

Trait Rumination Predicts Elevated Evening Cortisol in Sexual and Gender Minority Young Adults.

Stress may contribute to illness through the impaired recovery or sustained activity of stress-responsive biological systems. Rumination, or mental rehearsal of past stressors, may alter the body's stress-responsive systems by amplifying and prolonging exposure to physiological mediators, such as cortisol. The primary aim of the current investigation was to test the extent to which the tendency to ruminate on stress predicts diminished diurnal cortisol recovery (i.

Buccal telomere length and its associations with cortisol, heart rate variability, heart rate, and blood pressure responses to an acute social evaluative stressor in college students.

Objective: Understanding the relationship between stress and telomere length (a marker of cellular aging) is of great interest for reducing aging-related disease and death. One important aspect of acute stress exposure that may underlie detrimental effects on health is physiological reactivity to the stressor.

Methods: This study tested the relationship between buccal telomere length and physiological reactivity (salivary cortisol reactivity and total output, heart rate (HR) variability, blood pressure, and HR) to an acute psychosocial stressor in a sample of 77 (53% male) healthy young adults.

Correspondence between Heart Rate Variability and Emotion Dysregulation in Children, Including Children with ADHD.

Youth and adults with Attention-Deficit/Hyperactivity Disorder (ADHD) experience academic and social impairment and engage in risky behaviors. Emotion dysregulation (ED) is associated with ADHD and may contribute to these impairments and behaviors. Although many measures of ED exist, little is known about the physiological bases of ED, in the context of ADHD.

Stress-Induced Parasympathetic Control and Its Association With Inflammatory Reactivity.

Objective: It has been proposed that the inflammatory cytokine system is regulated through the vagus nerve, where vagal activation inhibits release of inflammatory cytokines and, therefore, inflammation. Thus, loss of vagal activation (i.e.
