With the support of the
Arnold P. Gold Foundation, we have developed a peer nomination survey
that may be useful as a selection tool for the Gold Humanism Honor Society.
For background information about this project, please view the PowerPoint
presentation "Can Peer Assessments Serve as a Tool
to Provide Consistent Measures of Humanistic Qualities?", from the
January 17-19, 2003 Gold Foundation barriers conference "Enhancing the
Culture of Medical Education: Assessing Humanistic Growth and Mission".
A 12-question survey was tested at the University of Florida, Tulane
University, and University of Michigan during 2003. Factor analysis of the
peer nomination survey data revealed three significant factors by which
medical students could be ranked for the identification of a top 10-15%:
clinical competence; caring (interpersonal skills & humanism); and community
service. Based on these results, a shorter, 6-question survey (please see
link below) was developed for testing at the same three medical schools in
2004. In other research, we have demonstrated that simply counting the
number of nominations for subsets of questions can be used to generate
virtually the same rankings as those generated by factor analysis, thereby
simplifying the data analysis using this survey. Two manuscripts have been
submitted for publication:
- "Evaluation of medical students by peer nomination: A simplified method
of data collection and analysis" by Wayne T. McCormack, PhD, C. Benjamin
Stevens, MS, and Parker A. Small, Jr., MD
- "Peer nomination: An overlooked tool to identify medical student
exemplars in clinical competence and caring" by Wayne T. McCormack, PhD,
Cathy Lazarus, MD, David Stern, MD PhD, and Parker A. Small, Jr., MD
Please note that this peer assessment format (peer nomination) does not
provide detailed information on every student. Peer rankings can provide
data on every student, but tends to be less discriminating (e.g.
everybody is "above average"). The greatest utility of peer nomination is
in effectively discriminating the extremes within a group, i.e. the
top ~15% of a medical school class in this application.

How and When To Administer the Survey:
Peer nomination forms may be administered as web-based or paper forms.
You may get a better return rate when administered as a paper form at a
meeting of the entire class, when the purpose of the survey can be
explained, instructions given, and sufficient time given to fill in names.
Web-based forms are convenient to administer and have the advantages of
being available at the students' convenience and data collection & reporting
may be automated, but medical students often need multiple reminders to
complete the form in a timely fashion. If on-line evaluation is part of your
local culture, then the use of web-based forms can result in good response
rates (85-99%).
The survey period can be at any time, but we believe that good peer
assessment requires good prior peer interactions, so we administer the form
as late as possible to have the data in time for GHHS selection and
preparation of MSPE's, which is during the summer preceding the fourth year
at Florida. The instructions should explain briefly what the data will be
used for at your institution, e.g. recognition for ~15% of the class by
election to the GHHS, mention in the the MSPE, other honors or awards, etc.
How To Analyze the Data:
Factor analysis can be used to analyze relationships among survey items and
to identify latent variables or "factors" that account for correlations
among the survey items. Factor analysis can also be used to assign scores to
individual students based on the major factors identified. For many years we
have used the SAS factor procedure and principal components analysis (SAS
Institute Inc, Cary, NC), with an eigen value greater than one to identify
major factors. The Harris-Kaiser rotation was used to determine standardized
regression coefficients, which were used to plot rotated factor patterns.
The SAS score procedure was used to list student scores for each factor,
which were then sorted in descending order to determine student rankings for
each major factor.
If you do not wish to use factor analysis, we have shown that you can obtain
virtually the same rankings of students by simply counting the number of
nominations that each student receives for each question. It is not
necessary to ask the students to rank their nominations 1st, 2nd, and 3rd,
as it will make no difference whether you weight the nominations or simply
count them. You can sum the numbers of nominations for subsets of questions
to arrive at rankings for the factors that have been identified by factor
analysis.
Factor 1 - Clinical Competence: Questions 1, 4, and 5
1. The classmates you would like to have work at your side in a medical
emergency.
4. The classmates who would be the best choices for a highly desired
residency. Residencies for future graduates will depend on these persons'
performance.
5. The classmates you would want as the doctor for yourself or a loved one.
Factor 2 - Caring (Interpersonal Skills/Humanism): Questions 2, 5, and 6
2. The classmates who best personify the quote "the secret of good patient
care lies in caring for the patient".
5. The classmates you would want as the doctor for yourself or a loved one.
6. The classmates who have the best listening skills with patients.
Factor 3 - Community Service: Question 3
3. The classmates who have shown exceptional interest in service to their
communities.
As described in our manuscript, Question 5 is interesting, as it has
characteristics of both Factor 1 and Factor 2.
What's With These "Factors"?
Review of the peer assessment literature reveals that two major
characteristics are consistently identified by factor analysis of peer
ratings by medical students, residents, and physicians: (1) medical
knowledge or technical skills; and (2) interpersonal skills or patient
relationships. Our peer nomination results for three medical schools
revealed the same pattern. We call Factor 1, which accounts for the most
variance, "clinical competence". One of the goals of our Gold
Foundation-sponsored study was to determine whether medical student traits
related to humanism and professionalism in medicine, such as caring,
respect, and altruism, would be identified as an independent factor in peer
assessment. We found that new peer nomination items related to humanism and
professionalism factored with interpersonal skills, prompting us to suggest
that a better description of Factor 2 may be simply "caring". We concluded
that medical students display their humanism via their interpersonal skills,
thus humanism could not be identified as an independent factor. Community
service was identified as a less significant third factor.
So Which Data Do I Use for GHHS Selection?
That, of course, is the $64,000 question, and one that your GHHS selection
committee must decide. Your selection committee should decide how to use the
data, and what additional data you want to use in your selection process.
Some medical schools rank students based on the grand total of nominations
each student receives for all of the questions. Others, including UF, rank
students for each of the three factors, and consider all three rankings, as
they provide information about different aspects of being a humanistic
physician. We also consider other data, such as peer ratings of professional
behavior, faculty ratings of professional behavior during clerkships, and
personal knowledge about the students among the selection committee members,
however the most weight is given to the peer nomination rankings.
Opinion:
I am posting a few comments about my personal opinion, because it is a
question I am often asked about how to use this peer nomination survey.
Obviously you and your GHHS selection committee should make your own
decision about how to incorporate such data into your selection process.
We have found that one can be overloaded with data when you compare
various rankings and other student data. Different subsets of students are
identified when students are ranked separately by Factor 1 and 2, with a few
students appearing on both lists of the top ~15%. Students who are ranked in
the top ~15% for both Factor 1 and Factor 2 are outstanding candidates for
GHHS selection. Beyond them, which rankings are the most useful? After all,
Factor 1 and 2 are both important - the best physicians are both clinically
competent and caring. Doctors may be extremely competent at medical
procedures but not very caring, and that might be OK in some situations, but
I don't think that is the kind of future physician we are trying to
recognize. The question is how to select students who are ranked high
according to one factor but not others. This is where additional data comes
into play.
I believe that the peer nomination process is a good way to get reliable
data about caring behavior, and that the Factor 2 ranking may be the most
relevant as a GHHS selection tool. We expect all of our medical students to
be clinically competent, and peer nomination can identify the standouts.
Other measures of performance and behavior can help ensure that those ranked
high for Factor 2 (caring) but not standouts for Factor 1 (clinical
competence) meet the standards you desire for GHHS selection.
Another debate your selection committee may have is how much emphasis to
place on Factor 3, community service. This ranking provides additional
information about one aspect of humanism in medicine. If a student is ranked
high for community service but does not appear in the top ~15% for clinical
competence and/or caring, other sources of information should come into play
in your committee's decision about GHHS selection. This ranking may also be
useful for selection of students for other awards specifically dedicated to
recognizing outstanding community service.
What Happens If We Change the Survey Questions?
We have tested several other survey questions, and most of them displayed
remarkably similar factor characteristics at all three medical schools.
However, some were not consistent across all three medical schools, such as
those related to likeability, discussing personally disturbing events, and
respect. Based on those observations, the six items on the current survey
were selected because they best defined each of the three factors and
resulted in consistent results by factor analysis at all three medical
schools. If you are concerned with having some uniformity with other medical
schools in the selection tools you use for the GHHS, I would certainly
recommend using the survey posted here, as we now have good data from three
different medical schools to validate it (soon to be published we hope!).
It is inevitable that some medical schools will change the survey
questions to best fit their local culture. If you plan to substitute
questions, my guess is that you are trying to tweak the survey to get at
elements of humanism you feel are most important for your institution. If
you plan to rank students according to individual factors, I recommend
performing factor analysis to ensure that new questions have the
characteristics you desire (and we would be happy to help you with that if
you cannot do it yourself). Based on our experience and results, I predict
that most substitute questions that ask about behavioral characteristics
related to caring, altruism, and empathy will be weighted towards Factor 2
when subjected to factor analysis. Adding different questions will likely
have less impact on the survey results than substituting questions. If you
plan to sum all of the nominations into a single peer nomination ranking,
ignoring the individual factors, changing the questions may have little
effect.
Several medical schools currently use this survey, or variations of it, as a
selection tool for their chapters of the Gold Humanism Honor Society (e.g.
see description of
2003 AAMC workshop presentation). Please feel free to use this survey at
your institution. Reference to our work (when published) would be
appreciated. If you have any other questions about how best to administer
the survey or interpret the data, please contact Dr. McCormack at (352)
