Abstract
The purpose of this study was to examine the association of psychosocial and other variables to pulmonary function over four months. Thirty-two patients with asthma kept daily records of pulmonary function and psychosocial variables for an average of 140 days. Data on other potential covariates of pulmonary function, as assessed by peak flow meters, were also collected (e.g., allergen exposure). Sixteen subjects (50%) had significant associations between pulmonary function and psychosocial variables. Between-subjects analyses showed small but significant associations between pulmonary function and other variables. These results confirmed previous reports of individual variability in the association of psychosocial variables with pulmonary function.
