the Era of NAS
Nancy Piro, PhDProgram Manager & Education SpecialistAnn Dohn, MADIO, Director of GMEGraduate Medical Education
Workshop Objectives
Understand how: – Evaluation impacts NAS– NAS impacts evaluations
Design and implement a valid & reliable resident evaluation process.
– Unintended cognitive bias – The impact of self-fulfilling prophesy– Evaluation questions
What Are Milestones ?
Defined areas of competency/expectations– We know what we expect of trainee– Trainee knows what is expected of them– Public knows what a ‘pathologist’, for example,
should know and be able to do when certified as … “competent to practice pathology without supervision”
Milestones
Levels (from Dreyfus)– Novice PGY-0– Advanced Beginner PGY-1– Competent PGY-2 and 3– Proficient Practitioner PGY-4/5– Expert Practitioner - Ongoing
Each trainee assessed with respect to level for each competency
Milestones
List of competencies to be attained by trainee Some milestones are still in development Milestones are within the ACGME existing 6 core
competencies
Each milestone is defined as continuum with respect to each level of competency from level 1 to level 5
Rating Scales: Levels 1 to 5
Where do these level 1-5 come from?Dreyfus Model in a Nutshell…
“In acquiring a skill by means of instruction and experience, the trainee normally passes through five developmental stages: 1. Novice
2. Competence
3. Proficiency
4. Expertise
5. Mastery”
Dreyfus Model (1980): Characteristics of each stage of developing expertise
1 Novice
* Rigid adherence to taught rules or plans* Little situational perception* No discretionary judgment
2 Advanced Beginner
* Guidelines for action based on attributes or aspects* Situational perception still limited* All attributes and aspects are treated appropriately and given equal importance
3 Competent
* Coping with 'crowdedness'* Now sees actions at least partly in terms of longer-term goals* Conscious deliberate planning* Standardized and routinized procedures
4 Proficient
* Sees situations holistically rather than in terms of aspects* See what is most important in a situation* Perceives deviations from the normal patterns* Decision-making less labored* Uses maxims for guidance, whose meaning varies according to the situation
5 Expert
* No longer relies on rules, guidelines or maxims* Intuitive grasp of situations based on deep tacit understanding* Analytic approaches used only in novel situations or when problems occur* Vision of what is possible

Milestone Level Definitions
Level 1: The resident is a graduating medical student/experiencing the first day of residency.
Level 2: The resident is advancing and demonstrating additional milestones.
Level 3: The resident continues to advance and demonstrate additional milestones; the resident consistently demonstrates the majority of milestones targeted for residency.
Milestone Level Definitions (continued)
Level 4: The resident has advanced so that he or she now substantially demonstrates the milestones targeted for residency. This level is designed as the graduation target – not requirement.
Level 5: The resident has advanced beyond performance targets set for residency and is demonstrating “aspirational” goals which might describe the performance of someone who has been in practice for several years. It is expected that only a few exceptional residents will reach this level.
Milestones
Making decisions about readiness for graduation is the purview of the residency program director.
What is NAS Driving Us to Do?
Change our Evaluations– Tagging current evaluation questions to core
competencies and milestones– Use direct milestone evaluations– Or use a combination
Ensure our evaluations are valid and reliable measures
Overall Milestone Evaluation Approach: Examples
Use Current Evaluations
EXAMPLE #1:Current
Map questions to milestones
EXAMPLE #2:Direct
EXAMPLE #3:Combo
Use Current Evaluations
Tag questions to milestones
Direct milestone evaluation
Direct milestone evaluation
Milestones Impact on Evaluations:Linking questions to milestones
Step Two: Ensure specific evaluation questions are linked to milestones
Advises the referring health care provider(s) about the appropriateness of a procedure in routine clinical situations
Milestone Evaluations demand valid, reliable evaluations as component measurements
Unintended bias can impact both direct and indirect milestone evaluations.
– Bias in questions & response scales (existing evaluations)– Bias in evaluators (all evaluations)
Halo Effect Devil Effect Similarity Effect Central Tendency Self-Fulfilling Prophesy
Step 1: Question and Response Scale Construction
Two Major Goals: Construct unbiased, focused and non-
leading questions that produce valid data
Use valid unbiased response scales
Step 1: Create the Evaluation-Eliminating Unintended Cognitive BiasWhat is cognitive bias?
Cognitive response bias is a type of bias which can affect the results of an evaluation if evaluators answer questions in the way they think they are designed to be answered, or with a positive or negative bias toward the trainee.
Step 1: Create the Evaluation - Where does response bias occur?
1. Response bias can be in the evaluators themselves: Central Tendency, Similarity Effect, First Impressions, Halo Effect, Devil Effect, Self-Fulfilling Prophecy
2. Response bias occurs most often in the wording of the question.
Response bias is present when a question contains a leading phrase or words
3. Response bias can also occur in the rating scales.
–
Response Bias in the Raters/Evaluators - Beware the Halo Effect
The “halo effect” refers to a type of cognitive bias where the perception of a particular behavior or trait is positively influenced by the perception of the former positive traits in a sequence of interpretations.
Thorndike (1920)
The Halo Effect and Expectations
The halo effect is discussed in Kelley's implicit personality theory…– “the first traits we recognize in other people
influence our interpretation and perception of later ones because of our expectations…”
The Halo Effect Extends to Products and Marketing Efforts
The iPod has had positive effects on perceptions of Apple’s other products…iPhones, etc.
Copyright © 2010 Apple Inc.
Could this impact our evaluations ?
A majority of trainees at Stanford believe that:
“The general feeling in my program is that your ability will be labeled based on your initial performance.”
GME House Staff Survey 2013-2014
“Reverse Halo Effect”
A corollary to the halo effect is the “reverse halo effect” (devil effect)
– Individuals or brands which are seen to have a single undesirable trait are later judged to have many poor traits…
- i.e., a single weak point (showing up late, for example) influences others' perception of the person or brand
Blind Spots
In the 1970s, the social psychologist Richard Nisbett demonstrated that we typically have no awareness of when the halo effect influences us (Nisbett, R.E. and Wilson, T.D., 1977)
The problem with Blind Spots is that we are blind to them…now on to self-fulfilling prophesy effect …
The Self-Fulfilling Prophecy (SFP)
First defined by Robert Merton in 1948 to describe:– ‘A false definition of a situation evoking a new
behavior which makes the originally false definition come true.’
What is the Self-Fulfilling Prophecy?
The Self-Fulfilling Prophecy (SFP)
Has been observed in many processes (Henshel, 1978)Within an individual, as with the placebo response
While the placebo effect occurs “within” the individual undergoing treatment, it is important to note that the individual’s belief derives from situational encounters with someone assumed to have expertise.
What is the Self-Fulfilling Prophecy?
Rosenthal’s Research on SFP
For more than 50 years, Robert Rosenthal has conducted research on the role of self-fulfilling prophecies in everyday life and in laboratory situations.
– Faculty expectations on trainees’ academic and clinical performance
– The effects of experimenters’ expectations on the results of their research (hence double-blinds)
– The effects of clinicians’ expectations on their patients’ mental and physical health.
The Pygmalion Effect: (Self-Fulfilling Prophesy)Sum it up: the greater the expectation placed upon people, the better they perform
Rosenthal and Jacobson (1968) reported and discussed the Pygmalion effect in the classroom at length.– In their study, they demonstrated that if teachers
were led to expect enhanced performance from some children, then the children did indeed show that enhancement.
Pygmalion in Education
The purpose of the experiment was to support the hypothesis that reality can be influenced by the expectations of others.
This influence can be beneficial as well as detrimental depending on which label an individual is assigned.
The observer-expectancy effect, which involves an experimenter's unconsciously biased expectations, is tested in real life situations. – Rosenthal posited that biased expectancies can
essentially affect reality and create self-fulfilling prophecies as a result.
Pygmalion Effect in Education
All students in a single California elementary school were given a disguised IQ test at the beginning of the study. These scores were not disclosed to teachers.
Teachers were told that some of their students (about 20% of the school chosen at random) could be expected to be "spurters" that year, doing better than expected in comparison to their classmates.
The spurters' names were made known to the teachers. At the end of the study all students were again tested with the same IQ-test used at the beginning of the study.
Pygmalion Effect
ALL six grades in both experimental and control groups showed a mean gain in IQ from pretest to post-test. – First and second graders showed statistically
significant gains favoring the experimental group of "spurters”.
– Conclusion: Teacher expectations, particularly for the youngest children, can influence student achievement.

Why ???
Anthropologists have postulated that accurate predictions in our human evolution came to be valued in and of themselves….
Other extensions…
“Dani is my shy child…” “Mike never eats his vegetables…” “I can’t see them making much progress…” “Michelle isn’t very coordinated….” “You will feel comfortable and heal very well
after this surgery” “I don’t expect Chris to make it through
residency, do you?”
Quotes…
James Rhem, executive editor for the online National Teaching and Learning Forum, commented:"When teachers expect students to do well and show intellectual growth, they do; when teachers do not have such expectations, performance and growth are not so encouraged and may in fact be discouraged in a variety of ways." "How we believe the world is and what we honestly think it can become have powerful effects on how things will turn out."
Step 1: Create the EvaluationQuestion Construction - Exercise One
Review each question and share your thinking of what makes it a good or bad question.
Question Construction: Exercise 1
Example 1: – "I can always talk to my Program Director about residency
related problems.” Example 2:
– “Sufficient career planning resources are available to me and my program director supports my professional aspirations .”
Example 3: – “Incomplete, inaccurate medical interviews, physical
examinations; incomplete review and summary of other data sources. Fails to analyze data to make decisions; poor clinical judgment.”
Example 4: – "Communication in my sub-specialty program is good.“
Example 5: – "The pace on our service is chaotic."
Question Construction - Test Your Knowledge
Example 1: "I can always talk to my Program Director about residency related problems."
Problem: Terms such as "always" and "never" will bias the response in the opposite direction.
Result: Data will be skewed.
Question Construction - Test Your Knowledge
Example 2: “Career planning resources are available to me and my program director supports my professional aspirations."
Problem: Double-barreled ---resources and aspirations… Respondents may agree with one and not the other. Researcher cannot make assumptions about which part of the question respondents were rating.
Result: Data is useless.
Question Construction - Test Your Knowledge
Example 3: "Communication in my sub-specialty program is good."
Problem: Question is too broad. If score is less than 100% positive, researcher/evaluator still does not know what aspect of communication needs improvement.
Result: Data is of little or no usefulness.
Question Construction - Test Your Knowledge
Example 4: “Evidences incomplete, inaccurate medical interviews, physical examinations; incomplete review and summary of other data sources. Fails to analyze data to make decisions; poor clinical judgment.”
Problem: Multi-barreled ---Respondents may need to agree with some and not the others. Evaluator cannot make assumptions about which part of the question respondents were rating.
Result: Data is useless.
Question Construction - Test Your Knowledge
Example (5): – "The pace on our service is chaotic.“
Problem: The question is negative, and broadcasts a bad message about the rotation/program.
Result: Data will be skewed, and the climate may be negatively impacted.
Evaluation Question Design Principles
Avoid ‘double-barreled’ or multi-barreled questions. Eliminate them from your evaluations.
A multi-barreled question combines two or more issues or “attitudinal objects” in a single question.
More examples….
Avoiding Double-Barreled Questions
Example: COMPETENCY 1 – Patient Care
“Resident provides sensitive support to patients with serious illness and to their families, and arranges for on-going support or preventive services if needed.”
Evaluation Question Design Principles
Combining the two or more questions into one question makes it unclear which object attribute is being measured, as each question may elicit a different perception of the resident’s performance.
RESULTRespondents are confused and results are confounded leading to unreliable or misleading results
Tip: If the word “and” or the word “or” appears in a question, check to verify whether it is a double-barreled question.
Evaluation Question Design Principles
Avoid questions with double negatives… When respondents are asked for their agreement
with a negatively phrased statement, double negatives can occur.
– Example:Do you agree or disagree with the following statement?
Attendings should not be required to supervise their residents during night call.
Evaluation Question Design Principles
If you respond that you disagree, you are saying you do not think attendings should not supervise residents. In other words, you believe that attendings should supervise residents.
Phrase the questions positively if possible. If you do use a negative word like “not”,
consider highlighting the word by underlining or bolding it to catch the respondent’s attention.
Evaluation Question Design Principles
Because every question is measuring “something”, it is important for each to be clear and precise.
Remember…Your goal is for each respondent to interpret the meaning of each survey question in exactly the same way.
Pre-testing questions is definitely recommended!
Evaluation Question Design Principles
If your respondents are not clear on what is being asked in a question, their responses may result in data that cannot or should not be applied to your evaluation results…
Example: "For me, further development of my medical competence, it is important enough to take risks.”
Does this mean to take risks with patient safety, risks to one's pride, or something else?
Evaluation Question Design Principles
Keep questions short. Long questions can be confusing. Bottom line: Focus on short, concise, clearly
written statements that get right to the point, producing actionable data.
Short concise questions take only seconds to respond to and are easily interpreted.
Evaluation Question Design Principles
Do not use “loaded” or “leading” questions. A loaded or leading question biases the
response the respondent gives. A loaded question is one that contains loaded words. – For example: “I’m concerned about doing a
procedure if my performance would reveal that I had low ability”
Disagree Agree
Evaluation Question Design Principles
"I’m concerned about doing a procedure if my performance would reveal that I had low ability"
How can this be answered with “agree or disagree” if you think you have good abilities in appropriate tasks for your area?
Evaluation Question Design Principles
A leading question is phrased in such a way that suggests to the respondent that a certain answer is expected: – Example: Don’t you agree that nurses should show
more respect to residents and attendings? Yes, they should show more respect No, they should not show more respect
Evaluation Question Design Principles
Do use Open-Ended Questions Do use comment boxes after negative ratings
– To explain the reasoning and target areas for focus and improvement.
General, open-ended questions at the end of the evaluation can prove very beneficial– Often it is found that entire topics have been
omitted from the evaluation that should have been included.

Bias in the Rating Scales for Questions
The scale you construct can also skew your data, much like we discussed about question construction but luckily, for us…
Review your Program’s evaluations with the goalof eliminating any unintentional bias from them.
Take a look at the evaluations you use.– Identify questions which may have unintended
bias.– Modify questions to eliminate bias
Gentle Words of Wisdom - Avoid large numbers of questions….
Respondent fatigue – the respondent tends to give similar ratings to all items without giving much thought to individual items, just wanting to finish
In situations where many items are considered important, a large number can receive very similar ratings at the top end of the scale– Items are not traded-off against each other– Many items that not at the extreme ends of the scale or
that are considered similarly important are given a similar rating
Respondents quit answering questions at all…– Total Started Survey: 578– Total Completed Survey: 473 (81.8%)
Gentle Words of Wisdom - Begin with the End Goal in Mind
What do you want as your outcomes?
Be prepared to put in the time with pretesting.
The faculty member, nurse, patient, resident has to be able to understand the intent of the question - and each must find it credible and interpret it in the same way.
Gentle Words of Wisdom: Relevancy/Accuracy – Collect data in a valid and reliable way
If the questions aren’t framed properly, if they are too vague or too specific, it’s impossible to get any meaningful data.
Question miswording can lead to skewed data with little or no usefulness.
If you don't plan or know how you are going to use the data, don't ask the question!
Summary: Evaluation Do’s and Don’ts
DO’s Keep Questions Clear,
Precise and Relatively Short.
Use a balanced response scale
– Milestone scales are balanced
Use open-ended questions
DON’Ts Do not use Double+
Barreled Questions
Do not use Double Negative Questions
Do not use Loaded or Leading Questions.
