Stress and Disease: A Structural and Functional Analysis

Chronic stress, a validated health risk factor, remains an ambiguous construct in spite of years of research. We propose that chronic stress is best understood as a series of acute stress responses, and that these responses become maladaptive when they occur frequently or are of long duration. We focus on the factors that contribute to chronic stress: whether the presence of a stressor, real or imagined, is long‐lived and/or frequent (repeated activation), the degree to which the stressor is perceived as a threat even when no longer present (low or slow adaptation), and the extent to which the duration of responding is prolonged (delayed or failure to return to homeostasis). Importantly, we examine how perseverative cognitions (such as rumination and worry) contribute to chronic stress by creating and sustaining acute stress responses, largely via influencing activation, adaptation, and return to homeostasis. Finally, we discuss the implications of our stress model: that interventions can be ideographically tailored to address how an individual is experiencing chronic stress; that researchers may be better able to identify specific characteristics of chronic stress that relate most strongly to poor health; and that moderators of chronic stress may function through these contributing factors rather than via general effects on the system.     

How to Talk about Gender Inequity in the Workplace: Using WAGES as an Experiential Learning Tool to Reduce Reactance and Promote Self-Efficacy

Interventions aimed at raising awareness of gender inequity in the workplace provide information about sexism, which can elicit reactance or fail to promote self-efficacy. We examined the effectiveness of experiential learning using the Workshop Activity for Gender Equity Simulation ?C Academic version (WAGES-Academic) to deliver gender inequity information. To assess whether the way gender inequity information is presented matters, we compared WAGES-Academic to an Information Only condition (knowledge without experiential learning) and a Group Activity control condition. We predicted that only the information presented in an experiential learning format (i.e., WAGES-Academic) would be retained because this information does not provoke reactance and instills self-efficacy. Participants (n?=?241; U.S. college students from a large mid-Atlantic state university) filled out a gender equity knowledge test at baseline, after the intervention, and then 7?C11?days later (to assess knowledge retention). In addition, we measured feelings of reactance and self-efficacy after the intervention. Results revealed that participants in the WAGES condition retained more knowledge than the other conditions. Furthermore, the effect of WAGES vs. Information Only on knowledge was mediated by WAGES producing less reactance and greater feelings of self-efficacy. Results suggest that experiential learning is a powerful intervention to deliver knowledge about gender equity in a non-threatening, lasting way.     

Search for a curvilinear relationship between the sense of coherence and the intensity of PTSD in MVA survivors

The relationship between the sense of coherence (SOC) and the intensity of posttraumatic stress disorder (PTSD) was examined in order to determine its nature and to resolve the inconsistencies between (1) a growing body of empirical research that indicates a linear relationship between these variables, and (2) the schema-based theories of PTSD that suggest a curvilinear relationship between cognitions and the intensity of PTSD. In this cross-sectional study an attempt was also made to identify some psychological factors that moderate this relationship. Participants were a sample of 1132 motor vehicle accident (MVA) survivors. The results showed that gender and temperamental predisposition to PTSD constituted moderator variables of the relationship between SOC and the intensity of PTSD. This supported both the empirical evidence on the linear and negative relationship between SOC and the intensity of PTSD and the theories that postulated the curvilinear relationship.     

Rear negativity: Verbal messages coming from behind are perceived as more negative

Many studies have explored the evaluative effects of vertical (up/down) or horizontal (left/right) spatial locations. However, little is known about the role of information that comes from the front and back. Basing our investigations on multiple theoretical considerations, we propose that spatial location of sounds is a cue for message valence, such that a message coming from behind is interpreted as more negative than a message presented in front of a listener. Here we show across a variety of manipulations and dependent measures that this effect occurs in the domain of social information. Our data are most compatible with theoretical accounts which propose that social information presented from behind is associated with uncertainty and lack of control, which is amplified in conditions of self-relevance.
