Abstract
OBJECTIVES
Responses to health-related items on the Community Health Survey (CHS) provide evidence that is used to develop community-based health policy. This study aimed to assess the test-retest reliability of selected health behavioral items on the CHS according to item category, response period, and response scale.
METHODS
A sample of 159 men and women 20 to 69 years of age participated in a test-retest with an interval of 14 to 21 days. A total of 28 items relating to smoking, alcohol consumption, diet and weight control, and mental health were selected. We evaluated the test-retest reliability of the items using kappa statistics.
RESULTS
Kappa values ranged from 0.44 to 0.93. Items concerning habits had higher kappa values (mean, 0.7; standard error, 0.05) than items concerning awareness or attitudes (p=0.012). The kappa value of items with two- to four-point scales was 0.63, which was higher than the value of 0.59 for items with scales involving five or more points, although this difference was not statistically significant. Different kappa values were observed for each reference period, but no statistically significant differences were noted.
CONCLUSIONS
The test-retest reliability of the CHS items that we studied was associated with item category. Further study of the relationship between item category and reliability in domains other than health behaviors is required.

Abstract
<sec><title>OBJECTIVES</title><p>Our goal is to validate diagnosing and characterizing epilepsy based on a medical record survey by external reviewers.</p></sec><sec><title>METHODS</title><p>We reviewed medical records from 80 patients who received antiepileptic drugs in 2009 at two hospitals. The study consisted of two steps; data abstraction by certified health record administrators and then verification by the investigators. The gold standard was the results of the survey performed by the epileptologists from their own hospital.</p></sec><sec><title>RESULTS</title><p>The specificity was more than 90.0% for diagnosis and activity, and for new-onset seizures. The sensitivity was 97.0% or more for diagnosis and activity and 66.7-75.0% for new-onset epilepsy. This method accurately classified epileptic syndromes in 90.2-92.9% of patients, causes in 85.4-92.7%, and age of onset in 78.0-81.0%. Kappa statistics for inter-rater reliability and test-retest reliability ranged from 0.641-0.975, which means substantial to near-perfect agreement in all items.</p></sec><sec><title>CONCLUSIONS</title><p>Our data suggest that epilepsy can be well identified by external review of medical records. This method may be useful as a basis for large-scale epidemiological research.</p></sec>

Abstract
<sec><title>OBJECTIVES</title><p>The aim of this study was to evaluate whether clinical test values from different laboratories in the Korean Genome and Epidemiology Study (KoGES) can be integrated through a statistical adjustment algorithm with appropriate intra- and inter-laboratory reliability.</p></sec><sec><title>METHODS</title><p>External quality control data were obtained from the Korean Society for Laboratory Medicine and quadruplicated standardized serological samples (N=3,200) were manufactured in order to check the intra- and inter-laboratory reliability for aspartic acid transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transpeptidase (γ-GTP), blood urea nitrogen (BUN), creatinine, uric acid (UA), fasting blood sugar (FBS), cholesterol, and triglyceride (TG). As an index of inter- and intra-rater reliability, Pearson's correlation coefficient, intraclass correlation coefficients and kappa statistics were estimated.

Abstract
PURPOSE
Our main goal is to test the reliability and validity of the Korean version of Baecke questionnaire on physical activity by using 507 men and women aged 20-70 years.
METHOD
This study was carried out using the cancer screening participants of the National Cancer Center. All subjects were sent the Korean version of Baecke questionnaire by mail to measure their physical activity.
RESULTS
The mean score on the sport index during leisure-time for men was significantly higher than that for women. In contrast, the mean score of the work index for men was significantly lower than that for women. Cronbach`s alphas for work, sport and leisure-time index were 0.75, 0.81 and 0.39 for men, respectively, and 0.67, 0.75 and 0.35 for women respectively. By a principal components analysis the three conceptually meaningful factors were distinguished, except for the leisure-time factor. Due to the low cronbach`s alphas and undistinguished factors, work and sports factors were used on the final analysis, excluding the leisure time factor, in the Korean version of Baecke`s questionnaire. Two-factor analysis was used to assess the validity of work items and sports items. Work factor and sports factor were definitely distinguished as two factors. Multiple regression analysis showed that lean body mass was significantly related the work index(p<0.0001) and sports index (p<0.05).
CONCLUSION
Our results suggest that the modified Korean version of Baecke`s questionnaire is appropriate to assess the physical activity in Koreans.

Abstract
PURPOSE
Since 1988, the annual or biannual survey was conducted by Korean Association of Smoking and Health (KASH) to examine the smoking rate, knowledge and attitude on smoking of students attending middle and high school in Korea. The objective of this study was to investigate the test-retest reliability of self-administered smoking questionnaire for Korean middle and high school students.
METHODS
For the test-retest study, we sampled 30 school among 106 schools which participated in annual survey on June of 2002. Among 30 schools, 26 schools (86.7%) were responded for this study.
RESULTS
1) For the subjects of 1st and 2nd surveys, there were no difference on smoking related variable including attitude, knowledge, perceived health status, father's smoking status, friend's smoking status, willingness to smoke, and readiness to quit smoking 2) For middle school students among male, current smoking rates were 3.5% for 1st survey and 3.0% for 2nd survey, which was statistically no significant. For high school students, however, current smoking rate of 1st survey was higher (21.1%) than that of 2nd (18.2%), although the rate was not significantly differed. 3) For middle school students among female, current smoking rates were 1.1% for 1st survey and 3.3% for 2nd survey, which was statistically no significant. Corresponding rate for high school students were 9.8% and 11.4%, respectively.
CONCLUSION
The results indicated that smoking questionnaire has been conducted by KASH is reliable for use in estimation for prevalence of smoking for middle and high school students.
