Characteristics of Good Feedback
• Timely
• Specific
• Given in small quantities
• Non-evaluative
• Non-judgmental

Verbal Feedback in Surgery
• Prevalent surgical culture prone to negative and
evaluative feedback
• “Constructive criticism” thought to be the best way to
improve skills performance *
• Affects of feedback on teacher-learner relationships, and
learner motivation to study and practice not well studied
*Boehler ML, Rogers DA, et al. An investigation of medical students reactions to feedback: A
randomized controlled trial. Med Educ. 2006 Aug;40(8):746-9.
Study Questions
• How do positive and negative verbal feedback affect
immediate skills performance?
• What is the effect of such feedback on the teacherlearner relationship?
• What is the effect of such feedback on the trainee's
motivation to learn and engage in skills practice?
Study Specifics
25 1st year medical students with little
to no laparoscopic experience
Perform FLS peg- transfer.
Positive Verbal
Feedback (n=12)
Negative Verbal
Feedback (n=13)
Repeat FLS peg-transfer task.
Survey Administered
Debrief
Skills Performance Results
Interpreting Results
• No significant difference in skills performance (time and
number of errors)
• Could be due to non-specific nature of the feedback
• Most feedback in surgery is non-specific, learners unclear
how to improve
Survey Results
Interpreting Results
• Teacher- Learner Relationship
• Positive feedback from a mentor: relationship with that individual
would improve either somewhat (28%) or greatly (68%)
• Negative Feedback from a mentor: relationship with that
individual would deteriorate either somewhat (28%) or greatly
(72%).
• Individuals learn best from physicians they wish to emulate*

Interpreting Results
• Motivation to Learn
• Positive Feedback: either somewhat more (44%) or much more
(52%) inclined to learn about the subject. None reported a
decrease in interest in the subject.
• Negative Feedback: one-third would be either less inclined (24%)
or much less inclined (8%) to learn. Ten (40%) reported no
change in their level of interest, while the rest would be either
somewhat more inclined (20%) or much more inclined (8%)

Interpreting Results
• Motivation to Practice:
• Positive Feedback: most would spend somewhat more (60%) or much
more (12%) time practicing, some reported no change in (24%) or
less (4%) practice time.
• Negative Feedback: few would practice less (12%) or the same (16%);
most would spend either somewhat more (36%) or much more (36%)
time practicing.

Conclusions
• Survey results only a pilot- need more longitudinal study
to determine veracity of results
• Unclear relationship of of verbal feedback to skills
performance
• The subtle affects of verbal feedback on motivation to
learn and practice need to be further researched
