Daily stress and anxiety and their relation to daily fluctuations of symptoms in asthma and chronic obstructive pulmonary disease (COPD) patients

Although stress and anxiety have long been assumed to play an exacerbatory role in asthma, no study has systematically documented that daily exacerbations of asthma symptoms are related to stress and/or anxiety. In this study, 24 airways obstruction patients (12 asthmatics and 12 chronic obstructive pulmonary disease patients) were instructed to monitor the severity of daily respiratory symptoms. In addition, subjects recorded their daily anxiety level and the number and perceived impact of daily stressors. The results showed that although there were differences between high- and low-stress days for both groups, there were no differences between groups on symptom severity or between high- and low-anxiety days, as measured by the State-Trait Anxiety Inventory (STAI). Thus, although the number and impact of daily stressors were found to be directly associated with the severity of asthma symptoms, anxiety does not appear to have a direct role in the exacerbation of asthma. The findings failed to support the anxiety theory of asthma but provided an explanation for the poor results obtained in previous treatment studies which employed anxiety management with asthmatics.     

Central clinical states: An examination of the Profile of Mood States and the Eight State Questionnaire

Two multidimensional mood-state inventories, the Profile of Mood States (POMS) and the Eight State Questionnaire (8SQ), were administered to 289 Australian college undergraduates. Intercorrelations for the combined 14 subscales were subjected to a higher-order factor analysis in order to elucidate the central clinical states within the mood-state sphere. Results suggested four major state dimensions pertaining to Neuroticism, Hostility/Anger, Vigor, and a combined Extroversion/Arousal-Fatigue entity. Both three- and five-factor solutions were taken out for comparative purposes. Furthermore, separate higher-order factorings of the POMS on normative samples of 350 male and 650 female psychiatric outpatients were conducted, corroborating three of the four central state dimensions, at least in the case of females. The implications of these findings for behavioral assessment are discussed.This study was supported by a Research Development Grant awarded to the author by the University of Melbourne.     

Strategic and tactical limits of comparison studies

A comparison study is an experiment whose primary purpose is to compare directly (regardless of experimental design) at least two different procedures for changing behavior or two or more components of such a procedure. This paper argues that, in spite of their popularity, such studies typically lead to inappropriate inferences with poor generality based on improper evidence gathered in support of the wrong question, thus wasting the limited experimental resources. The discussion considers problems concerning the functions of comparison studies, the nature of the comparisons that are attempted, the generality of their findings, and the limited role that they can play in technological research.     

Creating a Career Hotline for Rural Residents

The authors describe a career information hotline for rural and farm residents affected by the farm crisis as one way a university career center and extension division can make their resources more generally available to residents. The rural crisis is real, but a crisis brings opportunities. There are opportunities to provide needed services and help ease the personal cost for families and reduce the declining quality of life in rural communities. (Heffernan & Heffernan, 1985, p. 17)
