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.     

Social support coping style predicts women’s cortisol in the laboratory and daily life: the moderating role of social attentional biases

Background and Objectives: Social stress and associated coping responses can profoundly influence women’s stress physiology and health. Implicit social attentional biases can also influence psychological and physiological stress responses. The purpose of this study was to explore whether a coping style characterized by greater use of social support predicts indices of cortisol activity in laboratory and daily life contexts among female university students. We hypothesized that the relation of this coping style to cortisol activity would be moderated by women’s attentional biases.

Methods: Seventy-four women (M_age?=?19.44, range: 17.8–27.8, 64% White) completed an interpersonal stress task and an attentional bias task in the lab, along with a self-report coping inventory. Participants provided five saliva samples during the lab protocol, followed by three saliva samples per day for three consecutive weekdays. Outcome measures included cortisol response to lab tasks (AUCg), diurnal cortisol slope, diurnal AUCg, and cortisol awakening response (CARi).

Results: A coping style characterized by greater use of social support predicted lower lab AUCg and lower, flatter average diurnal cortisol slope for women with attentional avoidance compared to women with attentional vigilance (ps?<?.05).

Conclusions: Responding to stress by using social support is linked to lower cortisol responses to social stress and diurnal cortisol activity for women with implicit avoidance of social threat cues.     

An examination of mindfulness skills in terms of affect tolerance among individuals with elevated levels of health anxiety

Background and Objectives: Affect tolerance factors, including anxiety sensitivity, intolerance of uncertainty, and emotional distress tolerance, have been implicated in the exacerbation of health anxiety. Therefore, identifying methods to improve affect tolerance in health anxious populations is imperative. Despite the link between mindfulness and greater affect tolerance in non-clinical populations, no work has examined the role of mindfulness skills in terms of affect tolerance among individuals with elevated health anxiety. The aim of the current study was to examine the unique contribution of mindfulness skills in terms of distress tolerance, anxiety sensitivity, and intolerance of uncertainty.

Methods: Participants were 218 undergraduates with clinically elevated levels of health anxiety (75.7% female; M_age?=?19.53, SD?=?3.16, Range?=?18–45) who completed self-report measures for course credit.

Results: Findings indicated that, after controlling for theoretically relevant covariates, greater acting with awareness, non-judgment, and non-reactivity were uniquely associated with greater distress tolerance, and greater non-reactivity was associated with lower levels of intolerance of uncertainty. Though none of the mindfulness skills emerged as specific individual predictors of anxiety sensitivity, these skills collectively accounted for unique variance in anxiety sensitivity.

Conclusions: These findings suggest that mindfulness skills may be helpful in targeting affect tolerance factors among individuals with elevated health anxiety.     

Individual differences in the impact of attentional bias training on cardiovascular responses to stress in women

Abstract

Experimental studies show that training people to attend to negative stimuli makes them more likely to respond with greater anxiety to stress. The present study investigated this effect in students using measures of cardiovascular responses to stress and examined whether individual differences influence the impact of attention training on stress responses. Using a standard dot probe task, 30 participants underwent negative attentional bias training and 34 participants underwent anti-negative training before completing a stressful speech task. Results indicated that, overall, participants exhibited acclimatization to the procedures (indicated by a dip in blood pressure post-training) and normal stress responding (indicated by elevated blood pressure in response to stress; p<.001). However, consideration of participants’ scores for neuroticism/emotional-stability revealed important differences in how the intervention impacted on cardiovascular profiles (p=.008). For participants with high neuroticism scores, the negative attentional bias intervention elicited more exaggerated stress responding than the anti-negative intervention. For those with low neuroticism scores (i.e., emotionally stable participants), the anti-negative intervention was associated with elevated post-intervention blood pressure and higher blood pressure reactivity to stress. These findings provide evidence of the impact of attentional bias manipulation on physiological stress reactivity and suggest the effect is highly contingent on individual temperaments.     

Endocrine and emotional response to exclusion among women and men; cortisol,salivary alpha amylase,and mood

Background and Objectives: Social exclusion is ubiquitous and painful. Evolutionary models indicate sex differences in coping with social stress. Recent empirical data suggest different sex patterns in hypothalamic–pituitary–adrenal (HPA) and sympathetic–adrenal–medullary (SAM) reactivity. The present study sought to test this hypothesis.

Design: We examined differences in endocrine and emotional response to exclusion by using a virtual ball tossing paradigm (Cyberball). Saliva samples and mood ratings were collected to reflect levels before, and repeatedly following, exclusion.

Methods: The sample included 21 women and 23 men. Cortisol and salivary alpha amylase (sAA), biomarkers of the HPA and SAM systems, respectively, were used as indices of two arms of stress response.

Results: Following exclusion, all participants experienced mood worsening followed by mood improvement, with men reporting less distress than women. Women evinced decline in cortisol following the Cyberball task, whereas men’s cortisol levels showed a non-significant rise, and then decline, following exclusion.

Conclusions: Our results concur with previous findings showing SAM reactivity to be gender-neutral and HPA reactivity to be gender-divergent. Additional studies are needed to examine sex-specific response to social exclusion. Implications for individual differences in recovery from stress are discussed.     

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.     

When paying attention pays off: the mindfulness skill act with awareness promotes creative idea generation in groups

ABSTRACT

Past work has linked mindfulness to improved individual-level creativity, but remained silent about group-level creativity. Of all mindfulness skills, the ability to observe and attend to various stimuli (Observation) is the most powerful predictor of individual-level creativity. Studies examining effects of specific mindfulness skills on factors pertinent to group creativity suggest that for group-level creativity, the ability to focus attention with full awareness (Act with awareness), may be equally, or even more, important. We tested the relation between mindfulness and group-level creative idea generation using two brainstorming studies: one exploratory and one confirmatory. Mindfulness skills were either measured (Study 1; N = 88 groups) or the Act with awareness skill was targeted with a short, incidental guided meditation session (Study 2; N = 68 groups). Results from both studies showed differential relations between mindfulness and group creative idea generation: Only Act with awareness positively predicted the originality of ideas (Study 1 and 2) and the number of creative ideas in groups (Study 2). How mindfulness skills relate to creativity thus depends on the particular mindfulness skill involved and whether creativity happens at the individual or group level.     

Cortisol and behavioral reaction of low and high sensation seekers differ in responding to a sport-specific stressor

Background/objectives: Sensation seeking is closely related to practicing high-risk sports. This domain offers individuals an opportunity to achieve an increased level of arousal. Moreover, stress reactivity implies interindividual differences in the capacity to respond to a stressor. The purpose of this study was to examine whether high sensation seekers (HSS) compared to low sensation seekers (LSS) experience lower levels of stress on a physiological and psychological basis. Stress was induced in a sport-specific experimental paradigm with a climbing task through a jump into the rope.

Methods: Two extreme groups (n?=?28 male athletes) were examined in a mixed-factorial design (between: HSS vs. LSS; within: repeated measurements of several variables related to stress reactivity - cortisol, heart rate, anxiety).

Results: In response to the stressor HSS compared to LSS released a significantly lower amount of cortisol and needed less time for the climbing task. Heart rate and anxiety were not significant.

Conclusions: Individuals seem to react physiologically differently to a sport-specific stressor, depending on their level of sensation seeking. HSS seem to be less strained, and seem to perform better. These findings might be relevant not only for the evaluation of (sport-) psychological interventions but also for other contexts (e.g., special forces).     

Psychological,endocrine, and neural correlates of attentional bias in subclinical depression

Background: Our knowledge with respect to psychological, endocrine, and neural correlates of attentional bias in individuals with high vulnerability to developing depression – the subclinically depressed, still remains limited. Design: The study used a 2?×?2 mixed design. Methods: Attentional bias toward happy and sad faces in healthy (N?=?26) and subclinically depressed individuals (N?=?22) was assessed via a neuroimaging dot-probe attention task. Participants also completed trait and state psychological measures and provided saliva samples for cortisol analysis. Results: The subclinical group showed attentional bias toward happy faces; past use of problem-focused coping strategies when dealing with a personally relevant stressor as well as state levels of anxiety, together, contributed to this bias. In the control group, the happy attentional bias was positively correlated with activity in the right caudate. In the subclinical group, the bias was negatively associated with the left fusiform gyrus and positively with the left inferior parietal lobule and bilateral putamen. We observed group differences in association between cortisol levels during the task and neural activity during happy attentional bias processing within the key regions involved in attention. Conclusions: The attentional bias toward happy faces may reflect an active coping attempt by the subclinical participants.     

On anxiety-specific actions of tranquilizers

Abstract

This study examined the role of social support in the relationship between work demand and psychological distress (GHQ 12) in correctional officers (N=419), a high stress occupational group. Work demands were positively associated with strain. There was no evidence that social support buffered the negative impact of work demands. Rather, consistent with most previous research findings, support showed direct benefits and these were discussed in the context of worker participation and control. The hypothesis that officers high in negative affectivity, as measured by trait anxiety would show greater reactivity to work demands was not supported. However, trait anxiety appeared to inflate the relationship between work stressors (work demand and work support) and psychological distress supporting recent suggestions that the role of trait anxiety in occupational stress should not be disregarded. Trait anxiety combined additively with work demand to predict individual differences in psychological distress, however social support moderated the impact of trait anxiety on strain.     

Attentional control in OCD and GAD: specificity and associations with core cognitive symptoms

Obsessive–compulsive disorder (OCD) and generalized anxiety disorder (GAD) are both defined by excessive negatively-valenced cognitions. Although obsessional thoughts are considered essential to OCD and perseverative worry is considered essential to GAD, these excessive cognitions have been found to co-occur in both disorders. Accordingly, a common diathesis may influence the emergence of excessive thoughts in both disorders. The present study examined deficits in attentional control as a cognitive vulnerability that may contribute to both obsessional thought and perseverative worry. Patients with OCD (n = 30), GAD (n = 29), and non-clinical controls (NCC; n = 29) completed measures of obsessional thoughts, perseverative worry, and attentional control. Deficits in self-reported attentional control were found in both OCD and GAD relative to the NCC. However, attentional control was only related to excessive cognition in the GAD patient group, where deficits were associated with increased perseverative worry. Mediational modeling suggested that trait anxiety mediated the relationship between attentional control and perseverative worry in GAD. Implications of these findings for conceptualizing the role of attentional control in the genesis of excessive cognitions in OCD and GAD are discussed.     

Relationships between mindfulness,flow dispositions and mental skills adoption: A cluster analytic approach

ObjectivesThis study examines the relationships between mindfulness, flow dispositions and mental skills adoption.DesignCluster analytic approach.MethodsParticipants in this study were 182 university student athletes. They were administered the Mindfulness/Mindlessness Scale [MMS; Bodner, T., & Langer, E. (2001). Individual differences in mindfulness: The Langer Mindfulness Scale. Poster session presented at the annual meeting of the American Psychological Society, Toronto, Ont., Canada], Dispositional Flow Scale 2 [DFS-2; Jackson, S. A., & Eklund, R. C. (2004). The flow scale manual. Morgantown, WV: Fitness Information Technology] and Test of Performance Strategies [TOPS; Thomas, P. R., Murphy, S. M., & Hardy, L. (1999). Test of performance strategies: Development and preliminary validation of a comprehensive measure of athletes’ psychological skills. Journal of Sports Sciences, 17, 697–711].ResultsFour distinctive mindfulness clusters were found based on their response on the MMS using cluster analysis. Marked differences in flow dispositions and mental skills adoption habits were observed between the high and the low mindfulness clusters. Those in the high mindfulness cluster scored significantly higher than the low mindfulness clusters in challenge–skill balance, merging of action and awareness, clear goals, concentration and loss of self-consciousness scores of the DFS-2 [Jackson, S.A., & Eklund, R.C. (2004). The flow scale manual. Morgantown, WV: Fitness Information Technology]. The high mindfulness clusters also scored significantly higher compared to the low mindfulness cluster in terms of attentional control, emotional control, goal setting and self-talk sub-scales of the TOPS.ConclusionsThis study suggests that athletes’ flow dispositions and mental skills adoption could be differentiated using mindfulness. The findings have implications towards the understanding of flow and mental skills adoption within sport psychology.     

Cortisol,stress, and attentional bias toward threat

Abstract

Attentional bias toward threatening stimuli is a central characteristic of anxiety and acute stress. Recent small-scale studies have provided divergent perspectives on the association between the stress hormone cortisol and attentional bias toward threat cues. In a larger sample size than previous studies, we examined this association by investigating the impact of cortisol on attentional bias in two studies using a psychological stressor (N=35) and a physical stressor (N=65), respectively. Attentional bias and salivary cortisol were measured prior to and following the administration of a stressful task designed to increase cortisol levels. Results across these studies were equivocal relative to the association between baseline cortisol and baseline attentional bias. In addition, the association between acute change in cortisol and change in attentional bias appeared to differ as a function of the presence or absence of psychological stress. There was a trend toward a stronger negative association between acute cortisol change and attentional bias change among women relative to men. These results imply that the association between cortisol and attentional bias may be moderated by additional factors, such as gender or presence of stress.     

Socioemotional selectivity and psychological health in amyotrophic lateral sclerosis patients and caregivers: a longitudinal,dyadic analysis

Abstract

Objective: Socioemotional selectivity theory predicts that as the end of life approaches, goals and resources that provide immediate, hedonic reward become more important than those that provide delayed rewards. This study tested whether these goal domains differentially affected psychological health in the context of marital dyads in which one partner had been diagnosed with amyotrophic lateral sclerosis (ALS), a life-limiting disease.

Design: ALS patients (N?=?102) being treated in three multidisciplinary clinics and their spouses (N?=?100) reported their loneliness, financial worry and psychological health every 3 months for up to 18 months.

Main Outcome Measure: Psychological health composite.

Results: In multilevel dyadic models, patients and spouses had similar levels of financial worry and loneliness. Both patients and spouses had worse psychological health with higher loneliness, but only spouses had worse psychological health with higher financial worry. Significant interactions with age and disease severity indicated that older spouses were more affected by loneliness than were younger spouses, and patients with less severe disease were more affected by financial worry than patients with more severe disease.

Conclusion: The results provide good support for socioemotional selectivity theory’s implications for psychological health in a strong test of the theory.     

The relationship between dietary restraint and deficits in reasoning about causes of obesity

Abstract

Objective: Increased levels of dietary restraint are associated with deficits on many cognitive tasks. Less is known about how individual differences in restraint influences complex cognition such as reasoning which is the focus of this research.

Design: Two experimental studies are reported. In study 1, participants (n?=?158) completed a causal conditional reasoning task with statements about weight-related and general causal relationships. Study 2 replicated and extended study 1. Participants (n?=?108) completed a causal conditional reasoning task focusing on behavioural causes of weight change or general statements.

Main outcome measure: Causal conditional reasoning task performance.

Results: In study 1, levels of dietary restraint were negatively associated with reasoning abilities for weight-related statements only. Study 2 replicated the negative association between dietary restraint and reasoning finding the effect in both weight-related, and general, causal judgements.

Conclusion: The novel findings show that individual differences in dietary restraint have a wider relationship with cognition than previously demonstrated. Results tentatively support theoretical explanations of a reduction in cognitive capacity, rather than differences in belief, explaining reasoning deficits. These findings open an interesting avenue for research and might have implications for effective decision making about personal health behaviours, such as food choice.     

Yin yoga and mindfulness: a five week randomized controlled study evaluating the effects of the YOMI program on stress and worry

Background and objectives: The YOMI program is a psychoeducational training and physical practice-based program that bridges knowledge from evidence-based psychotherapy with the practice of mindfulness and yin yoga. It consists of 10 content-specific sessions and does not include home assignments. The primary purpose of this randomized controlled trial is to evaluate the effects of the five-week YOMI program on perceived stress, worry and mindfulness in a non-clinical sample.

Design and method: In this randomized controlled trial participants were assigned to two groups. Group 1 participated in the five-week intervention twice a week while Group 2 was assigned to a waiting-list condition and participated in the intervention after Group 1. All measures were administered through self-report questionnaires, conducted via a web-based program.

Results and conclusions: The results of the study indicated significant effects of the YOMI program on decreasing stress and worry, and increasing mindfulness. Notably these changes were still present at five-week follow up. Consistent with the hypotheses, results suggested that the YOMI program established a group setting where individuals learned to use tools and methods to facilitate better self-directed practice. The study shows moderate to large effect sizes.     

Should we suppress or reappraise our stress?: the moderating role of reappraisal on cortisol reactivity and recovery in healthy adults

Background: People differ in their ability to regulate their physiological stress response. Individual differences in emotion regulation strategies such as suppression and reappraisal may explain this differential response to stress.

Objective: The aim of the current study was to assess whether daily use of suppression and reappraisal as well as their interaction predicted physiological stress reactivity and/or recovery, as assessed by variations in cortisol levels.

Method: Thirty-eight healthy young adults (13 men) completed the Emotion Regulation Questionnaire and were exposed to a psychosocial stressor, throughout which salivary cortisol was measured.

Results: Linear regressions showed main effects of reappraisal and suppression on cortisol reactivity and a main effect of suppression on cortisol recovery, where both strategies were positively associated with stress phases. Moreover, results showed a significant interaction of suppression by reappraisal in predicting both cortisol reactivity and recovery. Simple slope tests revealed that reappraisal moderated the association between suppression and both phases of cortisol responsivity.

Conclusion: Our results suggest that reappraisal represents a protective factor against the deleterious effects of suppression on stress responsivity. This study underlines the importance of investigating emotion regulation strategies as a means to understand individual differences in vulnerability to stress-related psychopathologies such as anxiety and depression.     

Examining incremental explanatory power in accounting for worry severity: negative metacognitive beliefs uniquely predict worry severity following a worry episode

Background and Objectives: Contemporary conceptual models posit that different core variables contribute to worry, including intolerance of uncertainty (IU), metacognitive beliefs, and experiential avoidance. To date, a concurrent investigation of the incremental explanatory power of these variables in accounting for worry severity remains unexamined. The present study sought to address that gap in the literature.

Design/Methods: Participants endorsing frequent worry (N?=?127) completed self-report measures assessing IU, metacognitive beliefs, and experiential avoidance during an online session. Participants later attended an in-person lab-based session where they completed a worry episode and in-vivo worry severity was assessed following the worry episode.

Results: IU, negative metacognitive beliefs, and experiential avoidance each shared a bivariate association with post-episode worry severity. However, in multivariate analyses, only baseline worry severity and negative metacognitive beliefs surrounding the dangerousness and uncontrollability of worry predicted post-episode worry severity.

Conclusions: The present results further underscore links between negative metacognitive beliefs and worry.     

Effects of A Parenting-Focused Mindfulness Intervention on Adolescent Substance Use and Psychopathology: A Randomized Controlled Trial

Substance use and psychopathology symptoms increase in adolescence. One key risk factor for these is high parent stress. Mindfulness interventions reduce stress in adults and may be useful to reduce parent stress and prevent substance use (SU) and psychopathology in adolescents. This study tested the feasibility and effects of a mindfulness intervention for parents on adolescent SU and psychopathology symptoms. Ninety-six mothers of 11–17 year olds were randomly assigned to a mindfulness intervention for parents (the Parenting Mindfully [PM] intervention) or a brief parent education [PE] control group. At pre-intervention, post-intervention, 6-month follow-up, and 1-year follow-up, adolescents reported on SU and mothers and adolescents reported on adolescent externalizing and internalizing symptoms. Primary intent to treat analyses found that the PM intervention prevented increases in adolescent SU over time, relative to the PE control group. The PM intervention also prevented increases in mother-reported externalizing symptoms over time relative to the PE control group. However, PM did not have a significant effect on internalizing symptoms. PM had an indirect effect on adolescent-reported externalizing symptoms through greater mother mindfulness levels at post-intervention, suggesting mother mindfulness as a potential intervention mechanism. Notably, while mothers reported high satisfaction with PM, intervention attendance was low (31% of mothers attended zero sessions). Secondary analyses with mothers who attended?>??=?50% of the interventions (n?=?48) found significant PM effects on externalizing symptoms, but not SU. Overall, findings support mindfulness training for parents as a promising intervention and future studies should work to promote accessibility for stressed parents.

From self-reliers to expert-dependents: identifying classes based on health-related need for autonomy and need for external control among mobile users

ABSTRACT

Mobile health apps are seen as promising tools to support autonomous consumers in their quest for better health. However, individual differences in the need for autonomy and need for external control may impact the degree to which individuals perceive mobile health apps to be useful in their daily life. Using data from a representative sample of the Dutch population (N = 1,027), we applied latent class analysis to identify subtypes among mobile users based on their need for autonomy and need for external control, and to examine differences among these subtypes. We identified four subgroups: the self-reliers, confirmation-seekers, expert-dependents, and indifferents. Next to demographic differences, self-reliers and confirmation-seekers were generally more e-health literate and expressed more privacy concerns than the expert-dependents and indifferents. Our findings demonstrate that subgroups of people express different degrees of health-related need for autonomy and need for external control, which should be taken into account in online and mobile health communication efforts.
