摘要:

&NA;The present study of 375 female hospital workers assesses the impact of two specific dimensions of vocational stress on standing diastolic blood pressure. Both intrinsic (pertaining to job content) and extrinsic (associated with job context) stressors were examined in this study. Diastolic blood pressure was found to be significantly related to scores on an intrinsic stress measure, but not with the extrinsic one, even after the contribution of obesity and age levels were controlled. However, the effect of intrinsic stress was only found to be significant among women younger than 35. We believe this to be preliminary evidence that perceived dimensions of chronic intrinsic role stressors can be significant psychosocial correlates of diastolic blood pressure.

摘要:

&NA;Reports on the efficacy of the Minnesota Multiphasic Personality Inventory (MMPI) for selecting patients with valid complaints of pain have been equivocal. The Mensana Clinic Back Pain Test (MPT) was able to predict, with some degree of success, patients who had a definite organic pathologic condition. However, the MMPI measures personality traits, whereas the MPT measures the impact of pain on a patient's life. To determine which of the two tests would be a better predictor of actual physical abnormalities, and hence valid pain complaints, a comparison was undertaken between the two tests.The charts of 83 patients admitted to the Neurosurgery Service of Johns Hopkins Hopkins Hospital with complaints of back pain were assessed. MMPI test results, as well as test results for the MPT, were compared to the presence or absence of pathologic condition on electromyography, nerve conduction velocity studies, thermography, myelogram, or computerized axial tomography scan.The MPT had a correlation factor of ‐.59700, that was significant as P = .000005. Of the 52 patients scoring 17 points or less on the MPT, 85% had objective physical abnormalities, considered moderate or severe by blind review. Of the 31 patients scoring 18 points or greater on the MPT, only 26% had objective physical findings that were considered moderate or severe. Only the F scale (faking badly) of the MMPI correlated with objective physical abnormalities (r = .21340, P < .033). However, 60% of the patients with T scores of less than 70 on the F scale had objective findings, whereas 75% of patients with T scores greater than 70 had objective physical findings. Other MMPI scales did not correlate. Therefore, the MMPI cannot be considered a valid test for predicting the presence or absence of physical abnormalities, whereas the MPT could do so with greater reliability and validity. We conclude that the presence or absence of physical abnormalities occurs as an independent variable from personality traits, and the MPT is a better predictor of the validity of the complaint of pain than the MMPI.

摘要:

&NA;The purpose of this investigation was to determine the maximal cardiorespiratory responses of firefighters to stairclimbing work and to compare these responses to maximal treadmill exercise. Thirty‐eight firefighters volunteered to participate in the study. Maximal CR including oxygen consumption (VO2), ventilatory equivalent for oxygen (VE/VO2), minute ventilation (VE) and heart rate (HR) were measured during both stair climbing and graded treadmill exercise. The results showed that VO2 maxand HRmaxwere significantly lower, 7% and 2% respectively, and the VE/VO2was significantly higher (6.7%) during the stair‐climbing exercise. Maximal VE was not different between the two modes of exercise. The results suggest that since VO2 maxand HRmaxwere lower during stair climbing, the metabolic cost of firefighting tasks as related to VO2 maxon a treadmill may not be accurately reflected. Since stair climbing is a task‐specific activity for firefighters, it is recommended that testing of firefighters be performed on a stair‐climbing device, and that the difference in VO2 maxbetween treadmill and stair‐climbing exercise be considered when recommending a desired fitness level for firefighters.

摘要:

&NA;The conventional wisdom holds that workplace health promotion (HP) programs yield financial dividends, often generating cost savings. To examine the intellectual and empirical basis for this belief, we reviewed the literature on the economics of workplace HP programs. In general, in the literature published through early 1986, the claims of HP programs' profitability are based on anecdotal evidence or analyses seriously flawed in terms of assumptions, data, or methodology. Furthermore, certain aspects of the economics of HP programs have been virtually ignored. The dearth of sound evidence on the economic merits of workplace HP should not be interpreted as a negative assessment of the potential of such programs, however. Rather, it recommends a healthy skepticism in reading the literature and development of a new research‐based body of understanding.
