TL;DR: The stress response is subserved by the stress system, which is located both in the central nervous system and the periphery, and the principal effectors include corticotropin-releasing hormone; arginine vasopressin; proopiomelanocortin-derived peptides alpha-melanocyte-stimulating hormone and beta-endorphin; and the glucocorticoids.
Abstract: ▪ The stress response is subserved by the stress system, which is located both in the central nervous system and the periphery. The principal effectors of the stress system include corticotropin-releasing hormone (CRH); arginine vasopressin; the proopiomelanocortin-derived peptides α-melanocyte-stimulating hormone and β-endorphin, the glucocorticoids; and the catecholamines norepinephrine and epinephrine. Appropriate responsiveness of the stress system to stressors is a crucial prerequisite for a sense of well-being, adequate performance of tasks, and positive social interactions. By contrast, inappropriate responsiveness of the stress system may impair growth and development and may account for a number of endocrine, metabolic, autoimmune, and psychiatric disorders. The development and severity of these conditions primarily depend on the genetic vulnerability of the individual, the exposure to adverse environmental factors, and the timing of the stressful events, given that prenatal life, infanc...

TL;DR: These three-stressor results suggest that synergies may be quite common in nature where more than two stressors almost always coexist and suggest an immediate need to account for stressor interactions in ecological studies and conservation planning.
Abstract: Humans impact natural systems in a multitude of ways, yet the cumulative effect of multiple stressors on ecological communities remains largely unknown. Here we synthesized 171 studies that manipulated two or more stressors in marine and coastal systems and found that cumulative effects in individual studies were additive (26%), synergistic (36%), and antagonistic (38%). The overall interaction effect across all studies was synergistic, but interaction type varied by response level (community: antagonistic, population: synergistic), trophic level (autotrophs: antagonistic, heterotrophs: synergistic), and specific stressor pair (seven pairs additive, three pairs each synergistic and antagonistic). Addition of a third stressor changed interaction effects significantly in two-thirds of all cases and doubled the number of synergistic interactions. Given that most studies were performed in laboratories where stressor effects can be carefully isolated, these three-stressor results suggest that synergies may be quite common in nature where more than two stressors almost always coexist. While significant gaps exist in multiple stressor research, our results suggest an immediate need to account for stressor interactions in ecological studies and conservation planning.

TL;DR: Benefit finding was related to less depression and more positive well-being but also more intrusive and avoidant thoughts about the stressor and was unrelated to anxiety, global distress, quality of life, and subjective reports of physical health.
Abstract: The authors conducted a meta-analysis to examine the relations of benefit finding to psychological and physical health as well as to a specific set of demographic, stressor, personality, and coping correlates. Results from 87 cross-sectional studies reported in 77 articles showed that benefit finding was related to less depression and more positive well-being but also more intrusive and avoidant thoughts about the stressor. Benefit finding was unrelated to anxiety, global distress, quality of life, and subjective reports of physical health. Moderator analyses showed that relations of benefit finding to outcomes were affected by the amount of time that had passed since stressor onset, the benefit finding measured used, and the racial composition of the sample.

TL;DR: A 2-dimensional work stressor framework is used to explain inconsistencies in past research with respect to stressor relationships with retention-related criteria and suggested that the differential relationships between challenge stressor and hindrance stressors and the more distal criteria were due, in part, to the mediating effects of job attitudes.
Abstract: In this article, a 2-dimensional work stressor framework is used to explain inconsistencies in past research with respect to stressor relationships with retention-related criteria. Results of meta-analyses of 183 independent samples indicated that whereas hindrance stressors had dysfunctional relationships with these criteria (negative relationships with job satisfaction and organizational commitment and positive relationships with turnover intentions, turnover, and withdrawal behavior), relationships with challenge stressors were generally the opposite (positive relationships with job satisfaction and organizational commitment and negative relationships with turnover intentions and turnover). Results also suggested that the differential relationships between challenge stressors and hindrance stressors and the more distal criteria (withdrawal behavior and turnover) were due, in part, to the mediating effects of job attitudes.
