ObjectivesThis investigation aimed to determine the validity of
script concordance test (SCT), compared with clinical-case-related short-answer
management problems (SAMP), in fourth-year medical students.
MethodsThis retrospective study was conducted at the Medical
School of Lille University. Cardiology and
gynecology examinations both included 3 SCT and 2 clinical-case-related SAMP. Final score did not include SCT results, and
was out of 20 points. The passing score was ≥10/20. Wilcoxon and McNemar tests
were used to compare quantitative and qualitative variables, respectively.
Correlation between scores was also analyzed.
ResultsA total of 519 and 521 students completed SAMP and SCT in cardiology and
gynecology, respectively. Cardiology score was significantly higher in SCT than
SAMP (mean ± SD 13.5±2.4 versus 11.4±2.6, Wilcoxon test, p<0.001). In
gynecology, SCT score was significantly lower than SAMP score (10.8±2.6 versus
11.4±2.7, Wilcoxon test, p=0.001). SCT and SAMP scores were significantly
correlated (p <0.05, Pearson’s correlation). However, percentage of students
with SCT score ≥ 10/20 was similar among those who passed or failed cardiology
(327 of 359 (91%) vs 146 of 160 (91%), χ2=0.004, df =1, p=0.952), or
gynecology (274 of 379 (65%) vs 84 of 142 (59%), χ2=1.614, df=1, p=0.204)
SAMP test. Cronbach alpha coefficient was 0.31 and 0.92 for all SCT and SAMP,
respectively.
Conclusions Although
significantly correlated, the scores obtained in SCT and SAMP were
significantly different in fourth-year medical students. These findings suggest
that SCT should not be used for summative purposes in fourth-year medical
students.
