The relationship of praise/criticism to learning during obstetrical simulation: a randomized clinical trial
Aims:
The effect of positive vs. negative comments (praise vs. criticism) on trainees' subsequent cognitive and technical performance is unknown, but of potential importance. We performed a randomized trial of giving either praise or criticism during simulated normal vaginal deliveries (using a high-fidelity birthing simulator) to assess the differential effect of these types of comments on students' cognitive and technical performance, and perceived confidence after their learning experience.
Methods:
Medical and nursing students underwent stratified randomization to praise or criticism. Students (n=59) initially participated in a teaching demonstration and practiced normal spontaneous vaginal delivery using a birthing simulator. A baseline assessment of cognitive and technical skills, and of self-confidence, was followed by a second simulation during which positive or negative comments were given using standardized scripts. Cognitive performance, technical performance and confidence measures were then scored again.
Results:
Cognitive and technical performance scores in the "praise" group improved significantly by 2.5 (P=0.007) and 1.8 (P=0.032), respectively, while those in the "criticism" group remained unchanged. The self-reported confidence scores did not show any significant change from baseline in either group.
Conclusions:
Praise strengthens students' cognitive and technical performances, while criticism does not.
