Effects of Augmented Feedback on Cardiopulmonary Resuscitation Skill Acquisition: Concurrent versus Terminal

The purpose of this study was to find out the effects of augmented concurrent (AC) and augmented terminal knowledge of results (AT-KR) on cardiopulmonary resuscitation (CPR) skill acquisition. Method: The sample of 76 2nd year university students participated in the study. All study participants, who were determined to be eligible, completed a total of 4 hours of CPR training (2 hours a week). Immediately after the training, the pre-test (10 sets of CPR) was administered to determine the participants' baseline CPR skill level. Participants were then assigned into three groups, control and two experimental groups (AC and AT-KR), according to their sex and baseline CPR skill level. Participants in the AC group received a simultaneous visual feedback during CPR practice; participants in the AT-KR group received printed report of their performance after they finished CPR practice; and students in control group received no feedback related to their CPR performance. Upon completion of intervention, effects of feedbacks were measured as CPR performance improvement at post-test relative to pre-test. Findings: Students in the AC and AT-KR group performed better in some ventilation and compression skills than the students in the control group. Implications for Research and Practice: Usage of advanced technical feedback devices were recommended to enhance CPR skill acquisition.
