Living with Asthma. I. Genesis and development of a self-management program for childhood asthma.

This paper traces the roots of Living with Asthma, a self-management program for childhood asthma, from the Children's Asthma Research Institute and Hospital (CARIH), a residential treatment center in Denver, Colorado. The basic components of the program were developed and tested over the 40-year history of CARIH; the findings of an educational unit were added to this accumulated knowledge and expertise to complete the system. The program rests heavily on social learning theory, particularly two major tenets: 1) the concept of reciprocal determinism and 2) the learning/performance dichotomy. The crucial role of these concepts is described here, especially with respect to the design of the program and the selection of dependent variables. The remainder of this article describes the essentials of Living with Asthma, particularly the skills taught and performed by patients in a formal evaluation of the system. The design of the study, characteristics of patients enrolled in the program, and results obtained with the system are discussed. The program proved highly effective in significantly improving the knowledge of asthma in parents and their children, and in developing positive attitudes in both groups. It also produced significant reductions in the number of attacks experienced by the youngsters and improved their peak flow values. Participation in the program resulted in changes in morbidity indices of asthma, including significant reductions in school absenteeism and health-care costs incurred because of the disorder. These changes, it was concluded, reflected the result of the performance by patients of the self-management skills taught in Living with Asthma, coupled with the exceptional medical treatment they received.

Effects of instructions on pulmonary function values.

This study examined the influence of specific components of standard forced expiratory maneuver instructions on spirometric values. Thirty-six subjects received instructions and practice in performing the forced expiratory maneuver prior to experimental manipulation of instructions. Instructions to begin with a maximal inhalation and then to blow into the spirometer as hard, fast, and long as possible were reiterated prior to every maneuver. During the instruction manipulation period, subjects were additionally instructed to blow either harder, faster, or longer. Overall, instructions to blow harder resulted in the most stable pattern of increase in all measures (IC, FVC, FEV1, FEF25-75%, and FEV1/FVC); instructions to blow longer consistently led to decreases in some values.

Direct and indirect costs associated with the management of childhood asthma.

The financial impact of childhood asthma has not been assessed since Vance and Taylor reported their data in Annals of Allergy 13 years ago. The present study updates the financial impact the direct costs (e.g., physician fees) have on families and assesses the indirect expenditures (e.g., income loss) associated with managing a child's asthma.
