Development of a scale to assess occupational stress in Rural General Practitioners

One hundred and eighty-four physicians or General Practitioners (GPs) in the five Divisions of General Practice in Rural New South Wales, Australia, completed scales designed to assess Workplace Stressors, Negative Affect caused by stressors, General Work Stress, Other Stress, and General Health. GP Stress was positively correlated with Negative Affect, General Work Stress, poor Psychological Health, poor Somatic Health, Anxiety, Social Dysfunction, and Depression. Results showed that the Rural GP Stress Scale (scale that assessed the presence of stressors in the GPs' work environment) possessed concurrent or criterion validity. Factor analysis of GP Stress scores revealed Workload, Family and Leisure Considerations, Bureaucratic Interference, Education and Training Considerations, and Professional Isolation as five of the nine major stressors in the GPs' work environment. Re-testing, 4–6 weeks later, revealed that the Rural GP Stress Scale was highly reliable.     

Cognitive-Behavioral and Systematic Desensitization Procedures in Reducing Stress and Anger in Caregivers for the Disabled

Twenty-six highly stressed family and community caregivers for people with a disability completed scales designed to assess perceived stress, state anger, and trait anger. They were randomly divided into three groups. Subjects in one group underwent stress-reduction training in a self-instructional procedure, subjects in the second group underwent stress-reduction training in systematic desensitization, and subjects in the third group were placed in a wait-list condition. Results showed that state anger and trait anger were correlated with perceived stress at pretreatment, and state anger was correlated with perceived stress at posttreatment and follow-up. Subjects in both the self-instructional and systematic desensitization groups showed a reduction in perceived stress. Subjects in the self-instructional training group also showed a decrease in trait anger. The wait-list group showed no significant change in perceived stress and anger.     

Survey return rates for multiple-authored versus single-authored covering letters

Differences in response rates to a three-wave mail survey were assessed when the covering letters were signed by three versus one researcher. 375 surveys including covering letters signed by three researchers and 375 surveys including covering letters signed by one researcher were sent. A follow-up mailing was used to increase the response rate. 199 surveys were returned (53.5%) in which the covering letter had three researchers, and 218 when the covering letter had one researcher (58.7%), not a significantly different distribution.     

Stressors and Stress Reactions Among University Personnel

A large, ethnically diverse, and representative sample of university workers in administrative, instructional, and blue-collar/clerical support categories were administered a battery of questionnaires designed to assess job and nonwork stress, biopsychosocial reactions to stress, emotionality, medical symptoms and utilization, and perceived social support, among other variables. A total of 831 participants returned questionnaires. The principal results showed that job and nonwork stress correlated positively with behavioral, cognitive, and physiological reactions to stress as well as with negative emotionality. Job and nonwork stress correlated meaningfully with medical symptoms; nonwork stress also correlated at a useful level with reported medical utilization. Social support did not generally modulate reports of stress or reactions to stress. It was also found that support staff reported higher levels of nonwork stress and lower levels of work stress, but that 2 measures of job stress did not differentiate administrative and instructional personnel. Younger staff reported higher levels of job and nonwork stress, and females reported higher levels of nonwork stress, irrespective of job category. The results were discussed in terms of their importance for understanding the nature of stress among personnel on the university campus and in relation to prior research.     

Development of a Scale to Assess Posttraumatic Stress Disorder

This study presents a newly developed self-report Posttraumatic Stress Scale (PTSS) based on the DSM-IV (American Psychiatric Association, 1994). The scale assesses the trauma experienced by people via the specific criteria of reexperiencing, numbing and avoidance, hyperarousal, and functioning. The instrument was validated on 52 Vietnam veteran subjects diagnosed with posttraumatic stress disorder (PTSD), 64 subjects who were attending professional counseling for trauma-related incidents, and 176 subjects who had never been diagnosed with PTSD or had professional counseling. The test survey comprised the PTSS, Beck's Anxiety Inventory, Beck's Depression Inventory, Impact of Events Scale, the 12-item General Health Questionnaire, Inventory of Depressive Symptomatology, and Symptoms Checklist–90R. The test-retest reliability of the scale was assessed over a four- to six-week period. The scale had a high test-retest reliability and showed high convergent and concurrent validity. Construct validity as assessed through the comparison between the three groups was high; however, factor analysis revealed only two factors instead of the three factors assumed in the DSM-IV. Overall, the scale may be used by clinicians or clients.     

Effect of aerobic exercise on negative affect, positive affect, stress, and depression.

Three groups of subjects, 15 Longer-term Exercisers, 14 Short-term Exercisers, and 18 Nonexercisers completed questionnaires designed to measure negative affect associated with thoughts, negative affect associated with day-to-day experiences, positive affect associated with thoughts, and positive affect associated with day-to-day experiences, depression, and stress. All the subjects also provided a rating of their over-all general stress. The Longer-term Exercisers reported more positive affect associated with their thoughts and day-to-day experiences than the Nonexercisers. There also was a trend for the Longer-term Exercisers to report less over-all stress than the Nonexercisers.
