Anxiety Stress and Coping最新文献

Objective: This preliminary study examined the interactive influences of interpretation bias and emotion dysregulation in predicting autonomic stress response.Methods: Participants (N = 72 college students; ages 18-25, 70% female, 47% Hispanic/Latinx), completed a performance-based assessment of threat interpretation bias and self-report measures of emotion regulation difficulties. Electrodermal activity (EDA; skin conductance level) was collected while participants completed a standardized psychosocial stressor task.Results: Interpretation bias and emotion regulation difficulties interacted to predict EDA trajectories (β = 0.054, SE = .001, CI:.007, .002, p < .001) during acute stress: presence of either interpretation bias toward threat (β = 6.950, SE = 2.826, CI: 1.407, 12.488, p = .013) or emotion regulation difficulties (β = 9.387, SE = 3.685, CI: 2.141, 16.636, p = .011) was associated with greater reactivity and poorer recovery; presence of both was associated with the lowest resting state EDA and blunted reactivity (β = 1.340, SE = 3.085, CI: -4.721, 7.407, p = .66).Conclusions: Preliminary findings support interpretation bias and emotion regulation difficulties, and their distinct interactive patterns, as predictors of autonomic reactivity trajectories during stress. Interpretation bias modification and emotion regulation skills may be important intervention targets for common psychological conditions that are influenced by aberrant psychophysiological processes.

Background & objectives: Basic attentional control, negative biases in attention and interpretation, and rumination are all cognitive processes associated with depression; however, less is known about their predictive role in depressive mood reactivity and -recovery in response to stress, and their relation to severity of depression.

Design & methods: We experimentally induced stress based on an autobiographical imagery script in a sample of 92 participants with Major Depressive Disorder with or without comorbid anxiety disorders. We used simple regression analysis for investigating the roles of state- and trait rumination, attentional networks, and attentional and interpretation biases for predicting stress-induced depressive mood reactivity and -recovery, respectively, and whether they in parallel mediated the association between cognitive processes and depression severity.

Results: Stress-induced depressive mood reactivity was predicted by better orienting ability and more state rumination. Better recovery was predicted by better orienting efficiency and lower negative interpretation bias. Furthermore, the relation between state rumination and depression severity was partially mediated by depressive mood reactivity, however limited by the lack of temporal precedence in the analysis.

Conclusions: We characterized the relation between cognitive processes and mood malleability in response to stress. Findings could refine theoretical models of depression if causality is established.

Background: Meta-analyses of military deployment involve the exploration of focused associations between predictors and peri and post-deployment outcomes.

Objective: We aimed to provide a large-scale and high-level perspective of deployment-related predictors across eight peri and post-deployment outcomes.

Design: Articles reporting effect sizes for associations between deployment-related features and indices of peri and post-deployment outcomes were selected. Three-hundred and fourteen studies (N = 2,045,067) and 1,893 relevant effects were retained. Deployment features were categorized into themes, mapped across outcomes, and integrated into a big-data visualization.

Methods: Studies of military personnel with deployment experience were included. Extracted studies investigated eight possible outcomes reflecting functioning (e.g., post-traumatic stress, burnout). To allow comparability, effects were transformed into a Fisher's Z. Moderation analyses investigating methodological features were performed.

Results: The strongest correlates across outcomes were emotional (e.g., guilt/shame: Z = 0.59 to 1.21) and cognitive processes (e.g., negative appraisals: Z = -0.54 to 0.26), adequate sleep on deployment (Z = -0.28 to - 0.61), motivation (Z = -0.33 to - 0.71), and use of various coping strategies/recovery strategies (Z = -0.25 to - 0.59).

Conclusions: Findings pointed to interventions that target coping and recovery strategies, and the monitoring of emotional states and cognitive processes post-deployment that may indicate early risk.

Previous research on physiological indices of social anxiety has offered unclear results. In this study, participants with low and high social anxiety performed five social interaction tasks while being recorded with a thermal camera. Each task was associated with a dimension assessed by the Social Anxiety Questionnaire for Adults (1 = Interactions with strangers. 2 = Speaking in public/Talking with people in authority, 3 = Criticism and embarrassment, 4 = Assertive expression of annoyance, disgust or displeasure, 5 = Interactions with the opposite sex). Mixed-effects models revealed that the temperature of the tip of the nose decreased significantly in participants with low (vs. high) social anxiety (p < 0.001), while no significant differences were found in other facial regions of interest: forehead (p = 0.999) and cheeks (p = 0.999). Furthermore, task 1 was the most effective at discriminating between the thermal change of the nose tip and social anxiety, with a trend for a higher nose temperature in participants with high social anxiety and a lower nose temperature for the low social anxiety group. We emphasize the importance of corroborating thermography with specific tasks as an ecological method, and tip of the nose thermal change as a psychophysiological index associated with social anxiety.

Guided by the Family Stress Model for minority families, the present study examined the potential buffering effect of resting respiratory sinus arrythmia (RRSA), cognitive reappraisal, and mindfulness on the association between political climate stress (PCS) and anxiety symptoms in a sample of Latina and Black mothers. Participants were 100 mothers living in the southeastern United States. Mothers reported on PCS, cognitive reappraisal, mindfulness, and symptoms of anxiety. RRSA were measured during a resting task. Moderation analyses tested the influence of these three factors (RRSA, cognitive reappraisal, mindfulness) on the relation between PCS and anxiety. Results showed that the relation between PCS and anxiety symptoms was strongest at low levels of RRSA and cognitive reappraisal. At high levels of these two factors, there was no association between PCS and anxiety symptoms. Mothers with high levels of RRSA and cognitive reappraisal may be able to interact with and evaluate environmental stimuli in such a way that allows for adaptive adjustment, buffering against the negative impact of PCS. RRSA and cognitive reappraisal may be important targets of interventions designed to address the rising rates of anxiety symptoms in Latina and Black mothers.

Background and objectives: The trajectories of recovery and non-recovery following a disaster are well-documented, but the mechanisms of post-disaster adaptation remain poorly understood. Rooted in social cognitive theory and the transactional model of stress and coping, this study longitudinally investigated the reciprocal relations among coping self-efficacy (CSE), coping behaviors (approach and avoidant), and posttraumatic stress symptoms (PTSS) among highly exposed hurricane survivors.

Design: 261 Hurricane Florence survivors completed measures of hurricane-related CSE, coping behaviors, and hurricane-related PTSS across three timepoints, beginning 5-8.5 months after Hurricane Florence.

Method: Random-intercept cross-lagged panel models investigated the relations among study variables.

Results: Reciprocal, cross-lagged relations were identified between higher CSE and approach coping from T2 to T3. The lagged relations between approach coping at T1 and T2 were significant, as well as between avoidant coping at T2 and T3. Significant cross-sectional relations were also present for CSE, coping behaviors, and PTSS at T3.

Conclusions: Results provide partial support for the positive feedback loop involving CSE and approach coping, but not for the negative feedback loop involving avoidant coping. CSE may be an important mechanism in longer-term disaster recovery, in part by increasing use of approach coping.

Background and objectives: Previous research identified cognitive reappraisal as an adaptive emotion regulation strategy. However, theories on emotion regulation flexibility suggest that reappraisal effectiveness (RE) may depend on an individual's familiarity with stressors. In this study, we expect high reappraisal inventiveness (RI), i.e., the generation of many and categorically different reappraisals, to increase RE for individuals with low situational familiarity. Individuals with high situational familiarity, however, would be more effective with low RI.

Design: A total of 148 participants completed the Script-based Reappraisal Task, in which they were presented with fear- and anger-eliciting scripts. Depending on trial type, participants were instructed to reappraise (reappraisal-trial) or react naturally (control-trial) to the scripts. After each trial, participants indicated affective states and reappraisals. We assessed RI and calculated RE-scores as difference between affect ratings in reappraisal- and control-trials for valence and arousal. Finally, participants rated the familiarity with each situation.

Results: The results indicated a significant moderating effect of situational familiarity on the relationship between RI and RE-valence (not RE-arousal). The moderation was mainly driven by a detrimental effect of RI for individuals with high situational familiarity.

Conclusions: Our results hint at the importance of individual experience with emotional content in the research of cognitive reappraisal.

Background: Traumatic stress, suicide, and impulsive violence arguably are three of the most consequential problems facing societies today. Self-regulation shift theory is introduced to capture the underlying coping dynamics involved in these three grave challenges.

Objectives: Self-regulation shift theory, based in a nonlinear dynamical systems framework, focuses on critical psychological self-regulation thresholds and the role of cognitive self-appraisals in human adaptation to help understand these three significant societal challenges.

Methods: This essay reviews existing evidence within the posttraumatic adaptation process utilizing SRST for understanding dynamic self-regulation. This is followed by integrating SRST within existing current theoretical models for suicidal behaviors and violent outbursts.

Conclusions: The essay concludes with methodological suggestions for future research applying SRST and how this research offers important opportunities to develop early warning systems that promote hope when hope seems impossible.

Background and objectives: Psychopathology has been associated with a deficit in emotion regulation (ER) flexibility - the ability to flexibly utilize ER strategies that are appropriate to situational demands. Yet, whether anxious individuals can be taught ER flexibility, or whether ER flexibility is effective in managing negative affect, remains unknown. We investigated the impact of instructed ER flexibility on emotional responding among individuals with differing levels of anxiety.

Design and methods: Participants (N = 109) were taught two ER strategies (reappraisal, distraction) and randomized to be instructed in either flexible or inflexible ER while viewing images that differed in negative emotional intensity.

Results: When averaged over anxiety, or for participants with low anxiety, negative affect did not differ between conditions. However, among anxious participants, those in the flexible regulatory conditions - those who were instructed to flexibly switch between strategies - reported lower negative affect than those in the inflexible Reappraisal only condition, but not the Distraction only condition. The effectiveness of the two flexible conditions did not significantly differ.

Conclusions: Anxious individuals benefitted from being instructed in either ER flexibility or distraction. This finding supports literature on the adaptiveness of distraction and provides preliminary evidence linking instructed ER flexibility and improved emotional responding.

Background: Time pressure, commonly categorized a challenge stressor, consistently and positively relates to employees' experience of strain. However, regarding its relationship with motivational outcomes such as work engagement researchers have reported positive as well as negative effects.

Objectives: Drawing on the challenge-hindrance framework, we introduce two explanatory mechanisms (i.e., a loss of time control and an increase of meaning in work) which may explain both, the consistent findings related to strain (here operationalized as irritation) as well as the diverse findings related to work engagement.

Methods: We conducted a two-wave survey with a two-week time-lag. The final sample consisted of 232 participants. To test our hypotheses, we used structural equation modeling.

Results: Time pressure negatively and positively related to work engagement through loss of time control and meaning in work. Further, only loss of time control mediated the time pressure-irritation relationship.

Conclusion: Results demonstrate that time pressure likely acts motivating and demotivating at the same time, only through different paths. Hence, our study provides an explanation for the heterogeneous findings regarding the relationship between time pressure and work engagement.
