This pilot study examined the feasibility of computer aided instruction (CAI) as supplemental interactive nutrition education for patients requiring chronic dialysis. The CAI prototype was developed using Gagne's Model of Instructional Design and the Theory of Planned Behavior. Forty-two patients were enlisted from a chronic dialysis clinic and assigned randomly to either treatment or comparison group. All subjects completed pre- and post-test questionnaires regarding their phosphorus-rich food consumption habits. Each group received the usual phosphorus control education adjunct to the monthly lab review. The experimental group also received supplemental education by CAI. Serum phosphorus lab results were assessed for change after use of the CAI. Near significance was observed between the study group's phosphorus lab results difference means, t = 1.79, df= 40, p = .08. Comparison of pre-test and post-test data assessed changes in the dependent variables, attitude, perceived control, intent and behavior. The differences for the behavioral dependent variables means were not significant as determined by t-tests. The CAI was well accepted (m = 1.47 ± 0.95) by the subjects without respect to gender or age. Interactive CAI nutrition education was acceptable. Replication with a larger sample would allow opportunity to determine the significance of differences.
