Living with asthma: replications and extensions.

This article reviews replications and extensions of Living with Asthma, a self-management system developed and tested at the National Asthma Center in Denver between 1977 and 1980. Research on the system since the latter date has been conducted within the conceptual framework provided by the social or cognitive learning model. This approach has switched experimenter effort away from developing and evaluating the acquisition of self-management skills toward assessing their performance by patients. Efforts to insure these skills are used effectively by patients to control their asthma, focusing particularly on the assessment of performance variables, are described.

The "Asthma Self-Efficacy Scale".

According to Bandura, a person's expectations that a favorable outcome will follow a particular behavior are not sufficient to promote the occurrence of the behavior; the person must also believe that he or she will be effective at performing the behavior. The latter is referred to as self-efficacy. It has become a major focus in assessing patient performance of skills required to manage their illness. The present paper describes the development, testing, and applicability of an instrument for assessing self-efficacy in asthmatic patients. It notes that the Asthma Self-Efficacy Scale is not only a reliable paper-and-pencil instrument, but that it has a wide potential applicability throughout health care settings in measuring self-efficacy in asthmatic patients. The Asthma Self-Efficacy Scale is included.

Medication compliance in children with asthma.

The aim of the study was to determine whether self-management skills, when taught to asthmatic children and their parents, would improve medication compliance. The latter was assessed by a variety of procedures including serum theophylline levels, pill counts by parents, and self-monitoring measures. Results indicated a group receiving self-management training showed no greater gains in medication compliance, self-concept, or health locus of control than did a self-monitoring-only group. However, children in the former group became more responsible for initiating appropriate treatment for their attacks than did youngsters in the latter group.

Improving the ability of peak expiratory flow rates to predict asthma.

A major problem in the behavioral management of childhood asthma concerns recognition of the early signs of impending episode. An objective measure commonly used to aid recognition of early warning signs is the peak expiratory flow rate (PEFR). This study examined the ability of PEFRs to predict asthma within a 12-hour period; the prediction method used was based on prior and conditional posterior probabilities. Twenty-five children with asthma recorded their PEFR twice daily, and also recorded the date and time of their asthma episodes. Conditional posterior probabilities and the ratio of hits to misses were computed for each subject at successively lower flow rates. The average improvement in predictability from the prior probability to the highest posterior probability was 491%. The ratio of hits to misses and the number of episodes predicted, however, decreased as the posterior probability increased. Selection of the PEFR at lower posterior probabilities resulted in fewer prediction errors and led to prediction of a higher number of episodes than selection of the PEFR at the highest posterior probability.

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.

An intraindividual comparison of standard and mini-Wright scores.

The relationship between peak expiratory flow rate scores recorded with the standard Wright meter and those recorded with the mini-Wright meter was determined by correlating these scores on an intraindividual basis. These correlations were compared with correlations between pairs of standard scores. The latter were computed so as to provide an estimate of peak expiratory flow rate variability unrelated to recording apparatus. The results showed that pairs of standard Wright scores were more highly related to one another than were pairs of standard and mini-Wright scores. From these observations it was concluded that standard and mini-Wright scores are not equivalent and therefore may not confidently be interchanged.
