Effects of coping flexibility on cardiovascular reactivity to task difficulty

Extraversion is associated with lower cardiovascular reactivity to acute psychological stress

BACKGROUND AND AIMS

Extraversion has been associated with positive physical health outcomes, with adaptive cardiovascular responses to stress being one potential physiological mechanism. The present study examined the influence of extraversion on both cardiovascular reactivity and cardiovascular habituation to an acute psychological stress task (Paced Auditory Serial Addition Test (PASAT)) in a sample of healthy undergraduate students.

METHODS

A sample of 467 undergraduate students completed the Big Five Inventory (BFI) to assess trait extraversion and attended a single stress testing session. The testing session included two identical stress-testing protocols, each consisting of a 10-minute baseline and 4-minute PASAT. Cardiovascular parameters including heart rate (HR), systolic/diastolic blood pressure (S/DBP) and mean arterial pressure (MAP) were recorded throughout the testing session. State measures of positive affect (PA) and negative affect (NA), as well as post task measures of self-reported stress were used to assess psychological experiences of the stress task.

RESULTS

Extraversion was significantly associated with lower self-reported stress in response to the initial stress exposure, but not the second stress exposure. Higher levels of extraversion were associated with lower SBP, DBP, MAP and HR reactivity in responses to both exposures to the stressor. However, no significant associations were observed between extraversion and cardiovascular habituation to recurring psychological stress.

CONCLUSION

Extraversion is associated with lower cardiovascular reactivity to acute psychological stress and this relationship persists upon repeated exposures to the same stressor. Cardiovascular responses to stress may indicate a potential mechanism facilitating the association between extraversion and positive physical health outcomes.

Habitual use of psychological coping strategies is associated with physiological stress responding during negative memory recollection in humans

Research has identified a variety of strategies people use to cope with stress and that the adaptiveness of various strategies depends on the context in which they are used. However, important questions remain about the role of physiological stress response systems in supporting, influencing, or changing from coping strategies. This study works toward addressing this gap by examining associations between skin conductance level (SCL) and habitual use of coping strategies. It was hypothesized that more use of problem-focused strategies would be associated with SCL trajectories that were more stable and decreased less steeply, with the opposite trend hypothesized for more use of emotion-focused strategies. Participants were 188 college students (78% female) who reported their use of 14 coping strategies. SCL was recorded during recall of a negative family memory from childhood for five minutes. Trajectories of SCL during the recall were estimated with multilevel modeling. Greater self-distraction, planning, active coping, use of emotional support, and coping flexibility were related to trajectories of SCL that decreased less steeply and were more stable. Problem-focused coping and coping flexibility are, therefore, related to reduced SCL reactivity and promoting these skills may benefit mental health.

Coping flexibility: Variability, fit and associations with efficacy, emotion regulation, decentering and responses to stress

Coping flexibility is a promising approach to understanding risk and resilience, but it has been conceptualized in various ways. The aim of this study was to test convergence of coping-related flexibility measures with other coping-related competencies (coping self-efficacy, emotion regulation, decentering) and ways of coping. Participants were 885 students (M_age  = 21.5 years) who completed measures of flexibility (seven subscales), coping self-efficacy, emotion dysregulation, decentering, and ways of coping with recent interpersonal stressors. Breadth of coping was also examined, given its past use as a measure of flexibility. The seven flexibility subscales converged with each other as expected, and all were associated with greater coping-related competence, with moderate or large positive associations between the four measures of coping flexibility ability and other measures of coping-related competence. Regarding associations with ways of coping, multivariate models showed that perceived ability in coping flexibility had positive associations with engagement and negative associations with disengagement coping, but multiple situational/adaptive coping flexibility subscales were associated positively with both engagement and disengagement ways of coping. In addition, some findings were weak or counterintuitive, especially when ways of coping and breadth were considered, suggesting a need for more attention to precisely conceptualizing and appropriately measuring coping flexibility.

Coping with Stress, Executive Functions, and Depressive Symptoms: Focusing on Flexible Responses to Stress

Coping flexibility is conceptually similar to both inhibition and set-shifting. Though they serve different functions, all three are robustly associated with depression. Coping flexibility is the ability to relinquish a coping strategy regarded as ineffective and to devise and implement an alternative one; the concept is based on stress and coping theory. Inhibition is the ability to suppress responses selectively according to a change in the situation, while set-shifting is the process of switching flexibly between task sets, mental sets, or response rules. Inhibition and set-shifting are both executive functions in cognitive mechanisms. We hypothesized that coping flexibility was associated with a lower risk of depression, even when the effects of inhibition and set-shifting were controlled for. In total, 200 Japanese university students (100 women and 100 men) completed questionnaires that measured coping flexibility and depression and performed the Stroop Color and Word Test and the Wisconsin Card Sorting Test, which measured inhibition and set-shifting. We found that greater coping flexibility was associated with a lower risk of depression, even when the effects of inhibition and set-shifting were controlled for. Our findings suggest that, although coping flexibility is conceptually similar to inhibition and set-shifting, its association with depression differs from theirs.

Effects of Coping Flexibility in Young Women on Depressive Symptoms during Chronic Pain

Chronic pain is a worldwide problem that has a high prevalence rate and is often comorbid with depression. Coping flexibility, which is defined as the ability to discontinue an ineffective coping strategy-evaluation coping-and to produce and implement an alternative strategy-adaptive coping-has attracted much interest as an important factor that attenuates pain-induced stress responses, including depression. This study hypothesized that greater coping flexibility would be associated with lower depression in both women with chronic pain and those with menstrual pain. The participants included women with chronic pain (n = 292) and those with menstrual pain (n = 181) who completed questionnaires on pain intensity, pain acceptance, psychological inflexibility, and coping flexibility for chronic pain. The hierarchical multiple regressions revealed that both evaluation coping and adaptive coping predicted depression even after controlling for the effects of pain intensity, pain acceptance, and psychological inflexibility, which are well-known for their association with depression in patients with chronic pain. The hypothesis was supported in our samples. Our findings may contribute to the development of self-management without self-medication using over-the-counter analgesics by acquiring coping flexibility for chronic pain.

Stress coping strategies and stress reactivity in adolescents with overweight/obesity

This study explored the associations between the frequency and effectiveness of habitual stress coping strategies on physiological and psychological stress responses to an acute laboratory stressor in adolescents with overweight/obesity (51 adolescents; 47% female; ages 14-19 years). Coping strategies were assessed using the Schoolager's Coping Strategies Inventory. Acute physiological stress responses were measured as salivary cortisol and α-amylase output during the Trier Social Stress Test and during a control condition. Acute psychological stress was measured using a Likert-type scale, and systolic blood pressure (SBP) and heart rate were measured at baseline. Results revealed that higher coping effectiveness was associated with lower log-based α-amylase during the stress (β = -0.025, p = 0.018) and control (β = -0.030, p = 0.005) conditions, but not with cortisol across either condition (all ps > 0.05). SBP moderated the association between coping effectiveness and α-amylase during the stress condition, with higher coping effectiveness associated with lower α-amylase only among individuals with lower SBP (β = 0.002, p = 0.027). Coping frequency was not associated with cortisol responses, neither was habitual stress coping strategies associated with psychological stress (all ps > 0.05). These findings provide preliminary evidence that effective use of stress coping strategies may provide a dampening effect on sympathetic activity in an at-risk adolescent population.

Examination of the Coping Flexibility Hypothesis Using the Coping Flexibility Scale-Revised

Coping flexibility, as defined by the dual-process theory, refers to one’s ability to relinquish a coping strategy recognized as ineffective—abandonment—and to devise and implement an alternative and more effective strategy—re-coping. The coping flexibility hypothesis (CFH) dictates that richer coping flexibility produces more adaptive outcomes caused by stress responses, such as reduced psychological and physical dysfunction. We tested the reliability and validity of the Coping Flexibility Scale-Revised (CFS-R) and the CFH using the CFS-R, which was developed to measure coping flexibility. In total, we performed three studies involving 6,752 participants. Study 1 provided the psychometric properties of the CFS-R and tested this factorial structure by a confirmatory factor analysis. Study 2 estimated the validity of the CFS-R by examining the associations between its three subscales and variables that were conceptually similar to them. Study 3 tested the CFH using a longitudinal design after controlling for the effects of typical coping strategies and other types of coping flexibility. Overall, the CFH was supported by the use of the CFS-R, and the findings in Studies 2 and 3 showed that it had acceptable validity and reliability. Our findings implied that abandonment and re-coping can predict reduced depressive symptoms more than other types of theoretical framings for coping flexibility. Additionally, a meta-analysis of the Cronbach’s alphas for all samples in this study (k = 9, N = 6,752) showed that they were 0.87 (95% CI [0.87, 0.88]) for abandonment, 0.92 (95% CI [0.91, 0.92]) for re-coping, and 0.86 (95% CI [0.85, 0.87]) for meta-coping.
