OBJECTIVE This study attempted to determine the relationship of physiological indices of stress (ie, cortisol and salivary immunoglobulin A) to the effort-reward imbalance model (ERI). METHODS A sample of 98 direct-care disability workers completed the Work-Related Questions II-III and provided morning saliva samples on the same day of completion, which(More)
PURPOSE We assessed how 6 psychological performance enhancement techniques (PETs) differentially improved self-efficacy (SE) and skill performance. We also assessed whether vicarious experiences and verbal persuasion as posited sources of SE (Bandura, 1982 ) were supported and, further, if the effects of the 6 PETs remained after controlling for achievement(More)
OBJECTIVE To identify which factors best explain non-adherence to home rehabilitation exercises (HRE) for patients with musculoskeletal injuries. DESIGN Cross-sectional study. METHODS Participants (n = 87) aged 17-91 years completed questionnaires measuring demographic and injury-related information, self-efficacy, personality, health locus of control,(More)
Physiological indices of stress and ill-health (cortisol and salivary immunoglobulin A) were assessed to determine if they were predicted by Siegrist's effort-reward imbalance model (ERI) with an aim of identifying employees at risk of illness. Male Australian dairy farmers (N=66) completed the Perceived Stress Scale, Work related Questions II & III,(More)
OBJECTIVE This study explored the role of psychosocial factors in predicting both membership to either an irritable bowel syndrome (IBS) or control group, and the severity of IBS symptoms. METHODS A total of 149 participants (82 IBS and 67 controls) completed a battery of self-report inventories assessing disposition and environment, cognitive processes,(More)
OBJECTIVE To determine if cognitive processing, and subjective and physiological responses to stress and relaxation differed between an irritable bowel syndrome (IBS) group and control group. How these variables relate to the severity of IBS symptoms was also determined. METHODS Twenty-one IBS participants and 20 controls provided cognitive (attention and(More)
OBJECTIVE This study attempted to determine the relationship of physiological indices of stress (ie, cortisol and salivary immunoglobulin A) to the job strain and the job demand-control-support models. METHODS A sample of 98 direct-care disability workers completed the Maslach Burnout Inventory and the Job Content Questionnaire. In addition, participants'(More)
This experiment examined the effect of physical exercise on measures of cognitive performance, Raven's Matrices, and an adaptation of the revised WAIS arithmetic subtest. We also tested the inverted-U hypothesis of an interactive relation between exercise-induced arousal and cognitive performance. 50 physically active men were assigned to five groups (n =(More)
We assessed in an experimental design whether the stress response towards a work task was moderated by the autonomy to choose a break during the assigned time to complete the task. This setting is defined in accordance with the theoretical framework of the job-demand-control (JDC) model of work related stress. The findings from naturalistic investigations(More)
OBJECTIVE Despite considerable research into associations between the effort reward imbalance (ERI) model and various health outcomes over the past 20years, the underlying mechanisms responsible for the association remain unclear. Recently, ERI investigations have examined associations with immune sub-systems (e.g., leukocytes, cytokines and(More)
