Assessments of empathy in medical school admissions: what additional evidence is needed?

Introduction

The Association for the Study of Medical Education (ASME) sponsored a symposium on the theme of Examining the Evidence with Regard to Character, Personality and Values in Medical School Selection which was held on October 14, 2013 at the University of Sheffield Medical School in the United Kingdom. I was invited to speak about credibility issues related to personality assessments in health profession educations. To my pleasant surprise, I found the European audience receptive (more than their counterparts in the United States) to the idea of using personality assessments in admission decisions. There seems to be a hesitation among leaders in medical education in the United States to use personality assessments for selection purposes. They argue that convincing evidence is needed to support using personality assessments in medical school admission. In my presentation, I provided evidence to refute the argument against using personality assessments in admission decisions. Because of our extensive research at Jefferson Medical College on the topic of empathy in medical education and patient care, I placed the emphasis on credibility of evidence for using assessments of empathy, as a personality attribute, in the selection of applicants and professional development of students in any academic health profession institution. The editor of this journal who has a keen interest in medical education issues attended the symposium and suggested that I write an opinion piece about the issue for international audience of the journal. This editorial is based, in part, on my presentation at that symposium.

Why is personality relevant to medical school admissions?

There is a consensus among behavioral and social scholars that personality plays an unquestionable role in human behavior. In the practice of medicine, the importance of personality in professional assessments has been acknowledged in a paradigm of physician performance., There is a large volume of research in medical education about the contribution of personality to academic achievement, clinical competence, and specialty interest of doctors-in-training and in-practice. The notion that personality is a contributing factor to academic achievement, clinical competence, career choice, and professional behavior implies that personality should be considered as a pertinent measure not only for the assessment of professional development of doctors-in-training, but more importantly as an additional requirement for the admission of qualified applicants to medical schools.

Which personality attributes would be more credible?

A vast array of personality measures has been used in medical education research. The crucial question is which personality attributes are more credible for the assessments of professional development of doctors-in-training, and for consideration in the admission of applicants to medical schools? The choice of pertinent personality attributes should be based on the following three requirements:

Conceptual relevancy: the personality attributes of choice must be conceptually relevant to clinical competence and optimal patient outcome which is the ultimate goal of medical education. Obviously, a lack of clear conceptual relevancy between selected personality attributes and indicators of clinical competence and patient outcomes would not only undermine the potential value of the personality measures in medical school admissions, but also would make it totally unacceptable to medical education community.

Availability of psychometrically sound measuring instruments: a personality attribute that varies among individuals, varies to some extent, thus can be measured with a psychometrically sound instrument. In particular, in the context of medical education and patient care, the content, construct, criterion-related, and predictive validities; internal consistency (Cronbach’s coefficient alpha) and score stability (test-retest reliability) must be firmly established.

Empirical link to clinical competence and patient outcomes: the selection of the pertinent personality attributes must be evidence-based, meaning that convincing empirical evidence must support the significant associations between the selected personality attributes and indicators of clinical competence for doctors-in-training, and patient outcomes for doctors-in-practice. The question is which personality attributes in medical education and patient care can satisfy all of the three aforementioned requirements?

Is empathy a pertinent personality attribute?

There are some personality attributes that seem germane to clinical competence of doctors-in-training and in-practice. However, as described in a recent review article at the present time empathy seems to be a unique attribute that can meet all of the three aforementioned requirements.First, there is a consensus that empathy is an essential element of professionalism in medicine. Thus, it is conceptually relevant to clinical performance and patient outcomes. In the context of medical education and patient care, empathy is conceptualized as “a predominantly cognitive (as opposed to affective or emotional) attribute that involves an understanding (as opposed to feeling) of patients’ pain, experiences, concerns, and perspectives, combined with a capacity to communicate this understanding, and an intention to help.”- This definition makes a distinction between empathy (predominantly a cognitive attribute) and sympathy (predominantly an affective response) which engender different consequences in the context of patient care.,Second, there exists a psychometrically sound instrument, the Jefferson Scale of Empathy (JSE), which was specifically developed to measure empathy in the context of medical education and patient care. Prior to the development of the JSE a few instruments had existed for measuring empathy in the general population. However, none had face and content validities for measuring empathy in medical education and patient care. Relying on the aforementioned definition of empathy, about a decade ago the JSE was developed by our team at Jefferson Medical College to measure empathy in health profession education and patient care.,- The JSE contains 20 items, each answered on a 7-point Likert scale, and can be completed in approximately 5-10 minutes.The JSE has gained a broad reputation as a credible research instrument, has been translated into 42 languages, and used in more than 65 countries. Extensive data have been published in support of the JSE’s psychometric properties (e.g., construct,- criterion-related,,,15 and predictive validities, test-retest reliability, and internal consistency reliability,,15 on samples of medical students, doctors, and other health profession students and practitioners in the United States- and abroad.- More information about the JSE is posted at: www.jefferson.edu/jmc/crmehc/jse.html.Third, significant empirical associations have been reported between scores of the JSE on the one hand, and measures of clinical competence and patient outcomes , on the other hand. This is the most crucial requirement in support of the credibility of empathy assessment as an additional admission requirement. Despite the large volume of personality research in medical education, the evidence in support of a link between a physician’s personality and patient outcomes is extremely rare. However, there are some empirical studies that confirm significant associations between JSE scores and faculty’s ratings of students’ clinical competence, tangible patient outcomes in diabetic patients,, career interest of medical students, and specialty choice of doctors.

Persistent hesitation and resistance

Despite the aforementioned evidence, there remains a lingering doubt, persistent skepticism, and a lasting lack of enthusiasm to include assessments of pertinent personality attributes, such as empathy, in medical school admission decisions. Several factors contribute to the hesitation, including an unverified assumption that personality attributes (such as empathy) can be inferred from admission interview, letter of recommendation, personal statements, letter of intent, and essay. Ample evidence suggests that the validity of this assumption remains untested at the present time., - Some may be also concerned about possibility of respondent’s faking in self-reported personality tests. In response to this concern, we have described approaches to minimize so called “social desirability” response set., Another reason for the lingering doubt is that the validity evidence for personality measures in medical education is not strong enough to warrant their application in medical school admission decisions. On the surface, this argument appears to make sense; however, the predictive validity coefficients in medical education are often moderate, hovering around 0.30., Results of some meta-analytic studies show that the predictive validity coefficients of personality tests in general hover around 0.20., Therefore, the modest validity coefficients are not unique to medical education research and should not deter us from considering the assessment of applicants’ empathy in medical school admission decisions.In addition, some may be concerned about sociopolitical implications for using personality assessment (such as empathy), in medical school admission decisions. They argue that it would deny the opportunity to pursue a medical career for those who are academically qualified based on their scores of the admission tests (e.g., MCAT in North America, and UKCAT in the UK). I would challenge these skeptics to provide empirical evidence that the scores of these admission tests can predict students’ clinical competence and patient outcomes as well as those of the JSE!Medical schools may be willing to buy into the use of empathy assessments for monitoring professional development purposes. However, it is not sufficient to endorse the use of empathy assessments only for training purposes. It would be more desirable and cost-effective to select applicants who have already developed empathic orientation, than others who are steps behind (by their low scores on the JSE); thus need additional training to enhance their empathic understanding.

What should be done?

Medical schools are socially accountable to select “qualified” applicants with the best potential to become “good physicians”,, not just those who can successfully pass examinations of recalling factual knowledge in the early years of medical school. To offer or deny the opportunity to applicants to pursue medicine is a critical responsibility of medical schools. Inappropriate decisions during the admission stage would be detrimental to the medical profession, harmful to society, and can jeopardize public safety.The notion of social accountability in medical school admissions could lead to a potentially new legal challenge for medical schools (first brought to my attention by Joe Gonnella, MD). Perhaps, not in a distant future, medical schools could be summoned to the court of law for unprofessional conduct of their graduate, and interpersonal incompetence, and malpractice of those who were admitted to the medical school without assessments of their personal qualities, completed medical school curriculum without development of qualities pertinent to patient care, and granted a medical degree to practice a profession mismatched with their personality and character. To avoid such legal challenges, to render more optimal care, to regain reputation of the profession of medicine, and to reclaim compassionate image of doctors, bold actions must be taken to break free from unverified assumptions, unfounded notions, and sociopolitical considerations. What other evidence is needed to take the action at admission stage?
