Summary
This summary is machine-generated.

Positive feedback significantly improves laparoscopic surgical skills more than negative feedback, enhancing trainee confidence and reducing errors. Both feedback types are better than no feedback for skill acquisition.

Area of Science:

  • Medical Education
  • Surgical Training
  • Skill Acquisition

Background:

  • Simulation-based training (SBT) is crucial for skill acquisition in surgery.
  • The impact of positive versus negative feedback on skill acquisition and motivation in SBT is not well understood.

Purpose of the Study:

  • To compare the effects of positive feedback, negative feedback, and no feedback on laparoscopic skill acquisition and retention.
  • To evaluate the motivational implications of different feedback types in surgical trainees.

Main Methods:

  • A randomized controlled trial involving 42 medical students with no prior laparoscopic experience.
  • Participants received either positive feedback, negative feedback, or no feedback during a 2-hour training session.
  • Skills were assessed at baseline and one week post-training using the intracorporeal suturing assessment tool (ISAT); motivation was measured using the Intrinsic Motivation Inventory (IMI).

Main Results:

  • Both positive (76.8% ΔISAT) and negative (62.0% ΔISAT) feedback groups showed significant skill improvement compared to the control group (11.2% ΔISAT).
  • Positive feedback led to higher perceived competence and lower perceived pressure/tension compared to negative feedback.
  • Negative feedback was associated with increased tissue injuries during suturing.

Conclusions:

  • Both positive and negative feedback enhance laparoscopic surgical skills, with positive feedback yielding superior improvement.
  • Positive feedback boosts trainee intrinsic motivation and self-confidence, while negative feedback may lead to more errors and reduced confidence.
  • Feedback type significantly influences skill acquisition, retention, and the psychological state of surgical trainees.
