Abstract:
This study assessed differences in the knowledge of cardiac risk factors and the attitude toward computer assisted instruction (CAI) in cardiac rehabilitation patients instructed by lecture and transparencies or CAI. The quasi-experimental two-group posttest design used a convenience sample of 30 volunteers enrolled in a cardiac rehabilitation program. After randomization, cardiac risk factor instruction was conducted via lecture or the investigator developed CAI. The subjects completed a knowledge instrument which demonstrated content validity and a Kuder-Richardson formula 20 reliability coefficient of .0 and the Attitude Toward CAI scale which demonstrated content validity and a Cronbach's alpha .853 and .759. The data were analyzed by the two-sample t-test utilizing the .05 probability level. The results indicated a nonsignificant t value of .00 (df 28, p = 1.00) in the knowledge scores and a nonsignificant t value of 2.00 (df 28, p = .05) in attitude scores therefore the results failed to reject both null hypotheses. The conclusions drawn from this study are that CAI was as effective as lecture for patient education and that attitudes toward CAI were favorable.
