This study examines the effect of video self-instruction (VSI) on cardiopulmonary resuscitation (CPR) performance and attitude. A five-minute video clip of adult CPR was shown once to a five-minute VSI group, twice to a ten-minute VSI group, and three times to a 15-minute VSI group. CPR self-assessment scores and manikin assessed performance were collected twice, one before and one after VSI. A paired t-test was used to compare self-assessment scores from before and after VSI; one-way ANOVA was used to compare CPR scores. When self-assessment scores from before and after VSI were compared, the five-minute VSI group showed a statistically significant difference (p=.03) in performances; the ten-minute VSI group showed a statistically significant difference (p=<.00) in knowledge and performances; and the 15-minute VSI group showed a statistically significant difference (p=.02) in knowledge, performances, and attitude. When manikin-assessed performance was compared, the 15-minute VSI group had a score relatively close to the guideline. In terms of accuracy in artificial respiration, there was a statistically significant difference (p=<.00) among the three groups, with the 15-minute VSI group scoring the highest. Self-instruction through repeated viewing of CPR videos affected positively not only CPR knowledge but also performance and attitude.
