Promoting adherence: effects of theory-based asthma education
1University of Florida College of Nursing, USA.
Abstract:
This study compared the effects of a theoretically focused audiotape and a standard educational booklet on asthma preventive medication adherence and other asthma outcomes. Forty-six adult asthmatics were randomly assigned to receive either an experimental audiotape incorporating components of protection motivation theory, a standard asthma management booklet, both, or no educational materials. Outcomes were assessed at baseline, 3 months, and 6 months. Mean pharmacy-verified adherence improved 15% to 19% in the intervention groups and declined 22% in the control group at 6 months. Using analysis of covariance (ANCOVA) to control for baseline adherence, these changes were significant between the control and booklet group (t = 2.47; p = .02) and between control and combined group (t = 2.07; p = .04). Providing a minimal educational intervention can have a beneficial effect on asthma medication adherence that persists at least 6 months.
