PURPOSE Recently, the clinical practice examination (CPX) using standardized patients has been introduced into several specialty certifying examinations in Korea. The purpose of this paper was to determine the correlation of a resident's performance on the CPX with the comprehensive written multiple-choice question (MCQ) examination on the certifying examination for family medicine.
METHODS The subjects of this study were 1,023 residents who completed the 1st and 2nd certifying examination for family medicine between 2009 and 2011. We determined the correlation between the total scores and 4 domain scores (history taking, physical examination, patient education, and patient-physician interaction) on the CPX with the MCQ scores of the 1st written test and 2nd slide examination and the correlation between the total CPX score and scores on the CPX domains.
RESULTS The correlation between CPX score with each MCQ examination (0.21~0.45 with 1st written MCQ, 0.15~0.33 with 2nd slide MCQ) was lower than that between each MCQ examination (0.46~0.59). The CPX score on patient education did not correlate with the 1st written and 2nd MCQ scores.
The CPX scores on history taking and physical examination correlated slightly with the 1st written MCQ scores. The global ratings of preceptor examiners had the highest correlation (r=0.68~0.82) with the total CPX scores.
CONCLUSION Considering the mild correlation of CPX scores with each MCQ examination, the CPX is more likely to measure other qualities, such as critical thinking and communication skills.

BACKGROUND There has been widespread use of in-training examination for the evaluation of clinical competence of residents. The result of in-training examination seems to be helpful for improving the quality of residency programs using feedback system, further. We evaluated the relationship between residency program and the result of in-training examination.
METHODS Reports on the contents of residency program(82 programs) which were submitted in 1999 and in-training examination scores of 516 family medicine residents in 1998 were linked each other through the name of resident.
Correlation analysis, t test, ANOVA analysis, and the multiple linear regression analysis were used.
RESULTS Mean score acquired by residents of tertiary hospital residency program(59.4+/-7.79) was significantly higher than that of secondary hospital(56.4+/-8.45) among all three residency years. Residents who have seen their own patients in ambulatory care clinic(58.5+/-8.14) and were given feedback by peer review of teaching faculty(60.2+/-7.71) acquired significantly better results compared to those who have not(56.1+/-8.35, 57.5+/-8.27).
Residents in programs with moderate ratio of the number of residents to teaching faculty acquired significantly better results compared to those with smaller or larger ratio; the score were 56.2+/-6.90, 59.2+/-8.64, 58.7+/-7.90, 57.1+/-8.82 for the ratio of < or =3, 4-6, 7-9, and 9 <, respectively. Statistically significant but low correlation coefficients(less than 0.25) were observed between in-training examination score and the period of rotation to learn family medicine, general medicine, dermatology, musculo- skeletal problem, and the neuro-sensory problem.
After controlling probable confounders, third year of residency, residency program in tertiary hospital, and the moderate ratio of residents to teaching faculty were significantly associated with the better result of in-training examination.
CONCLUSION For improving clinical competence of residents in family practice, limiting the ratio between residents and teaching faculty in residency program to appropriate level and substantiality in contents of hospital teaching rotation program should be needed.

Item analysis is the evaluating process of items used for tests. Item difficulty, discrimination, and distractor analysis are the main components of the analysis.
Discrimination index(D) by the method of extreme groups had been used for the item discrimination, but it had been known to have some disadvantages compared to item-total correlation(ITC).
This study was conducted to evaluated the feasibility and the advantages of the ITC. Medical specialist qualifying examination carried out in Jan. 1999 was selected for the study material and the items of tests for the 4 major disciplines(internal medicine, general surgery, pediatrics, and obstetrics & gynecology) were analysed.
The numbers of the items and examinee are 120 items/428 persons, 140/219, 140/229, and 140/226 (in the order of IM, GS, Ped, OB & Gyn) respectively.
The average discrimination index(D) of all items is 0.170 and the standard deviation is 0.120. For the ITC, average is 0.210 and standard deviation is 0.117. There is positive correlation between D and ITC(r=0.677).
The variation of the ITC is 0.880, which is wider than that of discrimination index(D), 0.713. Especially on the items with item's p-value greater than 0.9(n=140), the variations are 0.542 and 0.273 respectively. The difference is much distinct.
These results imply that ITC can be used as the index of the item discrimination, and has some advantages compared to discrimination index(D). The advantages are the significance of the number itself and rather independence from the item difficulty.

As for the goal of medical education, it is generally accepted that it should provide the medical students with the ability to practice primary care. However, the medical education has been markedly dependent on the lecture and general hospital-based clerkship in Korea. This survey was conducted on the senior medical students (N = 209) who has been through with the entire curriculum of Seoul National University to assess the degree of satisfaction with the medical education and the ability to practice primary care.
We analyzed the useful answers of the 164 objectives. The mean age of the objectives was 24.2+/-1.0 years. The results were as follows : 1. The proportion of the students who answered that he (or she) was satisfied with the medical education was 30.5% (N = 50) and that of the unsatisfied was 54.3% (N = 89). 2. The proportion of the students who answered that he (or she) has ever practiced the suture of simple laceration was 11% (N = 18). 3. The proportion of the students who answered that he (or she) could not manage the acute diarrhea of children was 63.8% (N = 104). 4. The proportion of the students who answered that he (or she) could not manage the upper respiratory tract infection of adult was 29.3% (N = 48).
