Point-biserial correlations with selected academic performance measures are presented in
Table. The correlation of COMLEX-USA Level 2-PE with the weighted total numeric grade in the Physical Diagnosis course sequence was 0.41, while correlation with performance in the Osteopathic Principles and Practice course sequence was 0.37; both of these correlations were statistically significant at the .01 level. Correlations with GPAs were: year 1, 0.28 (
P<.05); year 2, 0.42 (
P<.01); and years 3 and 4 (combined), 0.30 (
P<.05). The interstation reliability (calculated via Cronbach α) for each third-year OSCE measure ranged from 0.36 to 0.76. The correlation of the COMLEX-USA Level 2-PE with the Physical Examination score on the third-year OSCE was 0.40 (
P<.01), and the correlation with the Total Station score (a weighted average of the Physical Examination, History, and SOAP Note ratings) was 0.33 (
P<.01). The correlation with the OSCE Communication score was 0.29 (
P<.05), and the correlation with the Professionalism score was 0.24 (
P<.05). The correlation of COMLEX-USA Level 2-PE with COMLEX-USA Level 2-CE was 0.29, (
P<.05), while the correlation with COMLEX-USA Level 1 written test was not statistically significant.
