This article evaluates the hypothesis that various stress management techniques have specific effects. Studies comparing various techniques are reviewed, as well as previous literature reviews evaluating the effects of individual techniques. There is evidence that cognitively oriented methods have specific cognitive effects, that specific autonomic effects result from autonomically oriented methods, and that specific muscular effects are produced by muscularly oriented methods. Muscle relaxation and/or EMG biofeedback have greater muscular effects and smaller autonomic effects than finger temperature biofeedback and/or autogenic training. EMG biofeedback produces greater effects on particular muscular groups than progressive relaxation, and thermal biofeedback has greater finger temperature effects than autogenic training. Disorders with a predominant muscular component (e.g., tension headaches) are treated more effectively by muscularly oriented methods, while disorders in which autonomic dysfunction predominates (e.g., hypertension, migraine headaches) are more effectively treated by techniques with a strong autonomic component. Anxiety and phobias tend to be most effectively treated by methods with both strong cognitive and behavioral components.

Eighty-six asthmatics completed measures of illness-specific panic-fear (i.e., panic-fear in response to symptoms of asthma) and of generalized panic-fear, dyspnea frequency, and catastrophic cognitions about bodily symptoms (the Anxiety Sensitivity Index [ASI] and Agoraphobic Cognitions Questionnaire [ACQ]). Asthma variables (self-report and pulmonary function tests) and cognitive variables (ASI and ACQ) were independently related to illness-specific panic-fear. Regression analyses showed that the cognitive variables predicted significant variance in both panic-fear scales after controlling for the effects of demographic and asthma variables. By contrast, the asthma variables were not associated with generalized panic-fear when the cognitive measures were controlled. In light of the adverse effects of panic-fear on asthma, the authors' results suggest that researchers may fruitfully explore the use of cognitive techniques as an adjunctive treatment for improving asthma outcome.
