Attachment--and loss.

This meta-analysis reviews 208 laboratory studies of acute psychological stressors and tests a theoretical model delineating conditions capable of eliciting cortisol responses. Psychological stressors increased cortisol levels; however, effects varied widely across tasks. Consistent with the theoretical model, motivated performance tasks elicited cortisol responses if they were uncontrollable or characterized by social-evaluative threat (task performance could be negatively judged by others), when methodological factors and other stressor characteristics were controlled for. Tasks containing both uncontrollable and social-evaluative elements were associated with the largest cortisol and adrenocorticotropin hormone changes and the longest times to recovery. These findings are consistent with the animal literature on the physiological effects of uncontrollable social threat and contradict the belief that cortisol is responsive to all types of stressors.

Acute stressors and cortisol responses: a theoretical integration and synthesis of laboratory research.

Perceived discrimination has been studied with regard to its impact on several types of health effects. This meta-analysis provides a comprehensive account of the relationships between multiple forms of perceived discrimination and both mental and physical health outcomes. In addition, this meta-analysis examines potential mechanisms by which perceiving discrimination may affect health, including through psychological and physiological stress responses and health behaviors. Analysis of 134 samples suggests that when weighting each study's contribution by sample size, perceived discrimination has a significant negative effect on both mental and physical health. Perceived discrimination also produces significantly heightened stress responses and is related to participation in unhealthy and nonparticipation in healthy behaviors. These findings suggest potential pathways linking perceived discrimination to negative health outcomes.

Inflammation and Its Discontents: The Role of Cytokines in the Pathophysiology of Major Depression

This chapter addresses the psychological effects of social stigma. Stigma directly affects the stigmatized via mechanisms of discrimination, expectancy confirmation, and automatic stereotype activation, and indirectly via threats to personal and social identity. We review and organize recent theory and empirical research within an identity threat model of stigma. This model posits that situational cues, collective representations of one's stigma status, and personal beliefs and motives shape appraisals of the significance of stigma-relevant situations for well-being. Identity threat results when stigma-relevant stressors are appraised as potentially harmful to one's social identity and as exceeding one's coping resources. Identity threat creates involuntary stress responses and motivates attempts at threat reduction through coping strategies. Stress responses and coping efforts affect important outcomes such as self-esteem, academic achievement, and health. Identity threat perspectives help to explain the...

Researchers benefit from controlling for individual differences that systematically account for variance in acute cortisol responses (e.g., sex). Similarly, some suggest that education could be used as a cortisol covariate because prior work found a negative relationship between education and the magnitude of acute cortisol responses in middle-aged adults. Nevertheless, education is seldom controlled for in tests of cortisol responses to acute stress, in part because the effect of education on acute cortisol responses has yet to be tested in a college sample. The present study therefore tested the relationship between education and cortisol responses to acute stress in college students. Participants (124 healthy undergraduate students) self-reported education level and were subjected to a stressful speech task. Salivary cortisol was collected 0, + 15, + 25, + 40, and + 55 min post-stressor onset. Participant also completed a battery of questionnaires assessing individual differences, day-to-day demands, and stress-related appraisals. Students in their fourth year of college education or above had significantly less curvilinear responses to the stress task relative to first-, second-, and third-year students. The effect of education on cortisol responses previously found in middle-aged adults was replicated in college students. Future research may therefore benefit from controlling for education when analyzing acute cortisol responses in college samples.

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

The COVID-19 pandemic has created a variety of stressors, some of which have been linked to intense stress reactions, such as posttraumatic stress (PTS)-like symptoms. However, we have limited knowledge on cumulative effects of pandemic-related stressors on PTS or on variables that may mitigate the effects of these stressors. We aimed to address some of these knowledge gaps by testing three models to examine the interrelationships among pandemic-related stressors, perceived social support, coping flexibility, and pandemic-related PTS. The sample of this cross-sectional correlational study is comprised of 2,291 adults from the United States who completed an online survey between May 22nd , 2020 and July 15th , 2020. Results indicated that greater exposure to secondary stressors, but not COVID-19-related stressors, was associated with increased PTS. After controlling for COVID-19-related and secondary stressors, social support had negative direct and indirect (via coping flexibility) effects on PTS. In addition, social support mediated the effects of COVID-19-related and secondary stressors on PTS. Our findings highlight the complexity of the role of social support in relation to pandemic-related stressors and PTS, and suggest that early interventions that target social support and coping flexibility may help reduce pandemic-related PTS.
