title: The Asthma Symptom Profile: a psychophysically based scale for assessment of asthma symptoms.
abstract: The Asthma Symptom Profile (ASP) assesses phasic changes in three dimensions of asthma symptoms: intensity, unpleasantness, and quality of sensations. Quantification data on verbal descriptors were gathered from 46 adult asthmatics for each of these scales, using bimodality scaling: i.e., with numerical estimates and drawing lines varying length. Close agreement was obtained between these two modalities. The ASP was analyzed before and after a bronchodilator in 44 asthmatics using ipratropium bromide (IB). Forty of these subjects were also tested in a placebo condition. Although ASP changes produced by IB were no greater than those produced by the placebo, correlations with changes in spirometry variables were significant. There were no significant differences in correlations with line drawings vs. numerical ratings. The ASP appears to be useful measure of phasic changes in asthma symptoms. Asthmatics with mild airway obstruction do not appear to be able to discriminate small changes in airway function.
