The Script Concordance Test: a new tool assessing clinical judgement in neurology.
BACKGROUND
Clinical judgment, the ability to make appropriate decisions in uncertain situations, is central to neurological practice, but objective measures of clinical judgment in neurology trainees are lacking. The Script Concordance Test (SCT), based on script theory from cognitive psychology, uses authentic clinical scenarios to compare a trainee's judgment skills with those of experts. The SCT has been validated in several medical disciplines, but has not been investigated in neurology.


METHODS
We developed an Internet-based neurology SCT (NSCT) comprising 24 clinical scenarios with three to four questions each. The scenarios were designed to reflect the uncertainty of real-life clinical encounters in adult neurology. The questions explored aspects of the scenario in which several responses might be acceptable; trainees were asked to judge which response they considered to be best. Forty-one PGY1-PGY5 neurology residents and eight medical students from three North American neurology programs (McGill, Calgary, and Mayo Clinic) completed the NSCT. The responses of trainees to each question were compared with the aggregate responses of an expert panel of 16 attending neurologists.


RESULTS
The NSCT demonstrated good reliability (Cronbach alpha = 0.79). Neurology residents scored higher than medical students and lower than attending neurologists, supporting the test's construct validity. Furthermore, NSCT scores discriminated between senior (PGY3-5) and junior residents (PGY1-2).


CONCLUSIONS
Our NSCT is a practical and reliable instrument, and our findings support its construct validity for assessing judgment in neurology trainees. The NSCT has potentially widespread applications as an evaluation tool, both in neurology training and for licensing examinations.
