A randomized comparison group pretest–posttest experimental design was used to determine computer‐assisted instruction effects on adherence to implementing house dust mite avoidance measures in adult atopic asthmatics. Fifty‐two subjects were randomly assigned to comparison and experimental groups. The comparison group received traditional instruction in avoidance measures while the experimental group received traditional instruction supplemented by identical information provided by computer‐assisted reinforcement of instruction. Adherence was measured by subjects' self‐ratings and investigators' observations. Data were collected during two home visits 12 weeks apart. The computer group had significantly (p < 0.05) greater adherence scores than the comparison group. The results indicate that computer‐assisted reinforcement of instruction is an effective method of increasing self‐care behaviors about allergen avoidance activities.
