“…Generally speaking, behavioural intervention strategies have produced a questionable level of relief (Alexander, 1972;Alexander et al, 1972Alexander et al, , 1979Danker et al, 1975;Philipp et al, 1972). Evaluation is also made difficult because of the lack of symptomatic or physiological data (Creer, 1970;Khan et al, 1977;Feldman, 1976;Lukeman, 1975) and the outstanding lack of follow-up data on those intervention strategies which may yield some positive benefit (Moore, 1965). The lack of positive findings in relation to the behavioural management of childhood asthma may be due to two important considerations.…”

“…Finally, insufficient attention has been given to the issue of self-control (i.e., control of the physiological response in the absence of biofeedback) which must be the end goal of biofeedback training (Epstein and Blanchard, 1977). Khan and Olson (1977) have conducted a study in which exercise is conceived as a conditioned stimulus. These authors hypothesize that exercise-induced asthma may be the result of faulty conditioning of the bronchial airways.…”

“…The long-term prospect of this approach for children suffering from exercise-induced asthma remains to be determined by future research. Some conceptual confusion seems to exist on the part of Khan and Olson (1977) in relation to the manner in which they discuss the deconditioning of exerciseinduced asthma. These authors use the term 'classical extinction' as a descriptor of the presentation of the conditioned stimulus (exercise) without the occurrence of the conditioned asthmatic response.…”

The behavioural management of childhood asthma has been critically reviewed with the focus on relaxation training, systematic desensitisation, assertive training, biofeedback and the use of deconditioning with exercise induced asthma. The authors conclude that there is a questionable level of relief from these behavioural intervention strategies and suggest that behavioural techniques may be better used in the management of asthma-related problems, such as the use of drugs and equipment, academic and social problems. The first part of this paper appears in the Australian Occupational Therapy Journal 1981, 28(2), 49-54.In a previous article in this journal, we reviewed the physiological and psychological aspects of childhood asthma (King and Murphy, 1981). In the current review, we focus upon recent developments in the psychological treatment (behaviour therapy) of childhood asthma. Although the vast range of treatment regimens for childhood asthma cannot be described here, it should be emphasized that drugs are the mainstay of therapy for asthmatic children. Aminophylline and theophylline, isoproterenol, epinephrine, disodium cromoglycate and cortico-

“…In addition, hypnotic suggestions of relaxation, well-being, and exercise without breathing difficulty has been shown to reduce the size of the bronchoconstrictor response to exercise from 31.8% FEV 1 decrease on control days to 15.9% under hypnosis (Ben-Zvi et al, 1982). Similarly, patients with exercise-induced asthma who had repeatedly experienced symptom relief by pre-exercise inhaler use were also more likely to show less exercise-induced obstruction when subsequently administered a placebo inhaler (visual inspection of the published figure suggested approximately 10% decline in FEV 1 with placebo compared to 25% without inhaler) (Khan and Olson, 1977). An overview of relevant studies in provided in Table 1.…”

Psychosocial factors have been found to impact airway pathophysiology in respiratory disease with considerable consistency. Influences on airway mechanics have been studied particularly well. The goal of this article is to review the literature on airway responses to psychological stimulation, discuss potential pathways of influence, and present a well-established emotion-induction paradigm to study airway obstruction elicited by unpleasant stimuli. Observational studies have found systematic associations between lung function and daily mood changes. The laboratory-based paradigm of bronchoconstrictive suggestion has been used successfully to elicit airway obstruction in a substantial proportion of asthmatic individuals. Other studies have demonstrated modulation of airway responses to standard airway challenges with exercise, allergens, or pharmacological agents by psychological factors. Standardized emotion-induction techniques have consistently shown airway constriction during unpleasant stimulation, with surgery, blood, and injury stimuli being particularly powerful. Findings with various forms of stress induction have been more mixed. A number of methodological factors may account for variability across studies, such as choice of measurement technique, temporal association between stimulation and measurement, and the specific quality and intensity of the stimulus material, in particular the extent of implied action-orientation. Research has also begun to elucidate physiological processes associated with psychologically induced airway responses, with vagal excitation and ventilatory influences being the most likely candidate pathways, whereas the role of specific central nervous system pathways and inflammatory processes has been less studied. The technique of emotion-induction using films has the potential to become a standardized challenge paradigm for the further exploration of airway hyperresponsiveness mediated by central nervous system processes.
