It has been suggested in personality and emotion theories that traits can influence emotional states and behaviour through interpretive processes such as cognitive appraisals. The present study investigated the relationships between Big Five personality dimensions and the cognitive appraisal processes associated with challenge and threat states in a large sample of municipal firefighters. The study assessed the Big Five traits and cognitive appraisal tendencies using a new measure of challenge-threat appraisal that measured appraisals directly and aggregated both across stressful situations and within six specific stressor domains. The results indicated that the Big Five traits related to overall challenge-threat appraisal and their accompanying primary and secondary components in unique and compelling ways, with some traits related more strongly to primary appraisals of situational demands and others related more to secondary appraisals of coping abilities. Overall, the results provide insights into how personality traits are associated with stress-related emotional experiences., (© 2021 John Wiley & Sons Ltd.)

This study examined the hypotheses that contingent self-esteem would be positively associated with alcohol-related problems and that global self-esteem would be negatively associated with such problems. It also examined the hypothesis that high stress and maladaptive coping would mediate these relationships. A sample of college students (n = 399) who were predominantly Hispanic (89%) completed measures of global and contingent self-esteem; stress and coping; and alcohol-related problems. Correlational and latent variable analyses indicated that contingent self-esteem positively related to alcohol-related problems, with maladaptive coping mediating this relationship. In contrast, global self-esteem negatively related to such problems, a relationship that was also mediated by maladaptive coping and stress. Overall, the results highlight the potentially harmful consequences of contingent self-worth and the adaptive nature of non-contingent self-esteem. They also demonstrate the important role that coping plays in mediating self-esteem's associations with alcohol-related problems., (Copyright © 2012 John Wiley & Sons, Ltd.)

We performed a series of meta-analyses examining the associations between coping and health-related outcomes in nonclinical adult samples. Results revealed that problem-focused coping was positively correlated with overall health outcomes, whereas confrontive coping, distancing, self-control, seeking social support, accepting responsibility, avoidance, and wishful thinking were each negatively correlated with overall health outcomes. Neither planful problem solving nor positive reappraisal was significantly associated with overall health outcomes in our analyses. However, type of health outcome (i.e., physical vs. psychological) and situational characteristics (i.e., stressor type, controllability, and duration) moderated many of the overall associations.

The impact of evaluative observation on cardiovascular reactivity and adaptation to recurrent psychological stress was evaluated in 162 undergraduate men and women. All participants performed three mental arithmetic tasks with or without evaluative observation. Impedance cardiographic, blood pressure, task performance, and stress appraisal measures were recorded for each task. Evaluative observation moderated the effects of task repetition on cardiac reactivity but not vascular reactivity. The introduction of evaluative observation disrupted cardiac adaptation, resulting in a resurgence of beta-adrenergic cardiac reactivity (p < .005), whereas the removal of evaluative observation promoted cardiac adaptation. Evaluative observation also increased stress appraisals and slowed task performance. The results support the dual process theory of habituation, rather than stimulus comparator theory, but only partially support cognitive appraisal theory.

The effects of prior task exposure on cardiovascular reactivity to stress were examined in two experiments by randomly assigning participants to repeated exposure groups that performed mental arithmetic pretest and test tasks versus delayed exposure groups that performed only the test task after prolonged rest. Impedance cardiographic and blood pressure measures were recorded continuously from 60 undergraduate men in Experiment 1 and 112 undergraduate men and women in Experiment 2. Task repetition attenuated cardiovascular reactivity and improved task performance in repeated exposure groups (p < .001), suggesting an integrated process of behavioral adaptation. During the test task, delayed exposure groups showed greater cardiac reactivity (p < .01), but not vascular reactivity, than repeated exposure groups. Thus, cardiac reactivity varied as a specific function of prior task exposure, whereas vascular reactivity varied as a general function of time.

In this study assertiveness as a moderator of stress reactions among women was examined. Specifically, the experimenters examined how high and low assertive women cognitively appraised, affectively and physiologically responded to, and behaviorally coped with the stress of giving an impromptu speech. High assertive women appraised the speech stressor as challenging, whereas low assertive women appraised the stressor as threatening. High assertive women also had a challenge pattern of autonomic response during the task, compared with the threat response of low assertive women. Afterward, the high assertive women reported experiencing less stress and negative emotion and greater positive emotion than did the low assertive women. Overall, the high assertive women's stress-related reactions indicated challenge, whereas the low assertive women's reactions indicated threat (see J. Tomaka, J. Blascovich, R. M. Kelsey, & C. L. Leitten, 1993).

This study investigated the moderating role of just world beliefs on stress and coping processes. Ss high and low in belief in a just world were asked to perform a potentially stressful laboratory task, which was repeated once. Cognitive appraisals and subjective, autonomic, and behavioral responses were recorded for each of the two tasks. The results supported a stress-moderating effect for just world beliefs. Individuals high in just world beliefs had more benign cognitive appraisals of the stress tasks, rated the tasks as less stressful post hoc, had autonomic reactions consistent with challenge (vs. threat), and outperformed Ss low in just world beliefs. Discussion centers on factors that moderate the experiences of challenge and threat in potentially stressful situations.

Autonomic responses were measured while 45 adult women performed a standard experimental stress task in the laboratory with only the experimenter present and 2 weeks later at home in the presence of a female friend, pet dog, or neither. Results demonstrated that autonomic reactivity was moderated by the presence of a companion, the nature of whom was critical to the size and direction of the effect. Ss in the friend condition exhibited higher physiological reactivity and poorer performance than subjects in the control and pet conditions. Ss in the pet condition showed less physiological reactivity during stressful tasks than Ss in the other conditions. The results are interpreted in terms of the degree to which friends and pets are perceived as evaluative during stressful task performance. Physiological reactivity was consistent across the laboratory and field settings.
