BACKGROUND While work-related fatigue has become an issue of concern among European employees, the relationship between fatigue, depression and work-related stressors is far from clear. The purposes of this study were (1) to determine the associations of fatigue with work-related stressors, severe medical disease, health behavior and depression in the working population and (2) to determine the...

While much research has focused on linking stressful experiences to emotional and biological reactions in laboratory settings, there is an emerging interest in extending these examinations to field studies of daily life. The current study examined day-to-day associations among naturally occurring daily stressors and salivary cortisol in a national sample of adults from the second wave of the Na...

Activation of the hypothalamo-pituitary-adrenal (HPA) axis by psychosocial stress is attenuated during lactation. We tested the hypothesis that lactating ewes will have attenuated HPA axis responses to isolation and restraint but will have greater responses to predator stress in the form of barking dogs. We imposed two 4 h stressors: psychosocial stress (isolation and restraint of ewes) and pre...

For generations, physicians have been struck by the powerful impact of stressors on the heart. Who has not seen cases of angina, myocardial infarction, arrhythmia, or sudden death in settings of emotional travail? Such phenomena are difficult to study, and it is so easy to find stress post hoc. After all, most of us could relate numerous significant stressors per week (and perhaps per day). How...

INTRODUCTION A Job Exposure Matrix (JEM) for psychosocial job stressors allows assessment of these exposures at a population level. JEMs are particularly useful in situations when information on psychosocial job stressors were not collected individually and can help eliminate the biases that may be present in individual self-report accounts. This research paper describes the development of a JE...

Previous research has revealed a persistent association between social structure and mental health. However, most researchers have focused only on the psychological and psychosocial aspects of that relationship. The present paper indicates the need to include the social and structural bases of distress in our theoretical models. Starting from a general social and psychological model, our resear...

We describe a novel preclinical model of stress-induced relapse to cocaine use in rats using social defeat stress, an ethologically valid psychosocial stressor in rodents that closely resembles stressors that promote craving and relapse in humans. Rats self-administered cocaine for 20 days. On days 11, 14, 17, and 20, animals were subjected to social defeat stress or a nonstressful control cond...

psychosocial stresses, as one of the causative factors of mental and physical disorders, are considered to be important health issues. thus, for identifying vulnerable groups, it is necessary to identify and evaluate these stressors. the purpose of this study is to review the relationship between stress and incidence of mental disorders and to quqntify this relationship and to compare psychiatr...
