Abstract: Objective To analyze and to evaluate the second stage clinical comprehensive skills examination results of clinical physician certification test by the students from Peking University Health Science Center.Methods Totally 188 students from Peking University Health Science Center have obtained valid results in the second stage of examination of clinical practitioners certification test in 2018.Those examination results were selected as the study subjects.SPSS 19.0 was used to test the internal consistency reliability,structural validity and criterion validity of the students' clinical comprehensive skill scores,and to analyze the differences among different groups of examinees.Results The average scores of the 188 students from 1~6 test stations of the clinical comprehensive skills examination were 9.81,13.67,12.72,7.25,16.56 and 16.94 respectively,with a total average score of 77.45.The internal consistency reliability Cronbach's alpha coefficient was 0.379 in the six test stations.The correlation coefficient between the scores of each examination station and the total scores of clinical comprehensive skills were 0.392~0.529.Spearman correlation coefficient r=0.320 between the results of the second and third stations.The correlation coefficient between the total scores of the first four stations of clinical comprehensive skills in the second stage examination and the scores of case analysis in the graduation examination was 0.286.The correlation coefficient between the total score of the 5th and 6th stations and the skill operation score of the graduation examination was 0.187.The correlation coefficient between the total score of clinical comprehensive skills in the second stage examination and the total score of clinical skills in the graduation examination was 0.347.There are slight differences in the examination results of different categories of students.Conclusions The reliability and validity of the second stage clinical comprehensive skills examination results of clinical practitioners certification in Peking University Health Science Center in 2018 are only mediocre and so further scientific analysis and rational design are needed.The university should strengthen the training of clinical reasoning and clinical skills of medical students.
