Objective: The Computer Learning in Pediatrics Project (CLIPP) program
comprehensively covers the COMSEP curriculum, and includes an exam based on
the content of simulated cases. We sought to validate the CLIPP exam as a tool
to assess medical student performance, based on item analysis and comparison
to the National Board of Medical Examiners (NBME) Pediatrics Subject exam.
Methods: After pilot testing the CLIPP exam, performance on individual
exam items was reviewed and problematic items were revised. Individual questions
on a 100-item CLIPP exam for students from 4 schools were analyzed using a commercial
software package. Students from two schools were administered both the NBME
and CLIPP exam. The student performance on the two exams was compared using
Pearson correlation statistics and chi-square analysis.
Results: Analysis of 100 individual exam items for 148 students shows
the average item R value is 0.196 (a positive correlation.) 128 students took
both exams. The average score for the NBME was 72.4, compared to 76.7 on CLIPP.
The Pearson correlation R score is 0.46 (p<0.0001). Chi-square analysis shows
that high or low performance on the CLIPP exam is predictive of similar performance
on NBME.
Conclusions: The individual CLIPP exam questions perform well at
discriminating high and low student performance on the CLIPP exam. Student performance
on the CLIPP exam correlates moderately well to NBME. The CLIPP exam is a feasible
and valid alternative to the NBME shelf exam.
