The relationship between asthma-specific quality of life and asthma control.
Few studies have quantitatively addressed the relationship between asthma-specific quality of life and asthma control as assessed by validated tools. Questionnaires were completed at home by a random sample of 542 adult asthmatic patients. The correlations of the two asthma control tools (Asthma Control Test and Asthma Therapy Assessment Questionnaire) with the quality of life tool (mini-Asthma Quality of Life Questionnaire) were strongest with the symptoms and activity domains (r = 0.63-0.77); lower with the emotions domain (r = 0.57-0.64); and lowest with the environment domain (r = 0.38-0.43). Asthma control tools reflect the symptoms and activity themes of asthma quality of life well, but reflect the environmental domain less well.
