  • Objectives : The purpose of this study was to evaluate the reliability of questionnaire according to item arrangement on patient satisfaction questionnaire. Methods : We developed the two types of questionnaire with different item arrangement. In the first type (A), questions were arranged according to medical service dimensions. Questions in the second type (B) were arranged according to medical process. Both questionnaires were composed of six dimensions: physical environments, process, competence, courtesy, information giving, understanding patients. Measurements were performed on a 5-score Likert scale. In an outpatients and inpatient survey, total 777 patients answered the type A (outpatients: 257, inpatients: 128) or Type B (outpatients: 257, inpatients: 135). In order to compare the internal consistency of two types. Cronbach's ${\alpha}$ were calculated. Multiple regression analysis was also performed to know which type of questionnaire explain more of the overall satisfaction. Results : In outpatient survey, type A questionnaire showed higher internal consistency than B except physical environments dimension. Also in inpatient survey, type A had higer internal consistency than B in four dimensions(process, competence, courtesy, understanding patients). In the results of multiple regression analysis, type A questionnaire ($R^2$=0.53) explained more of the variation in overall satisfaction then B questionnaire ($R^2$=0.43) in outpatient survey. In inpatient survey, type B questionnaire ($R^2$=0.40) explained, more of the variation in overall satisfaction than type A questionnaire ($R^2$=0.33).But the difference of R was not significant in inpatient survey. Conclusion : The results of this study support that type A questionnaire has higer reliability in assessment of consumer satisfaction than type B.

  • Objectives: The purposes of the study were to develop a questionnaire for dietary habit survey for Korean adults, and unify the terms related to dietary habits. Methods: The Delphi method by 43 professionals on dietary habit research was applied to unify the terms. Results: With regard to results on terms related to dietary habit, the respondents recorded the highest percentage (90.7%) of selecting the term "dietary habits" and also the highest percentage (76.7%) of choosing "dietary habits" for English. The biggest percentage of the respondents chose "individual dietary behaviors repeatedly formed and habitualized under the social, cultural, and psychological influence in the group" as the concept of dietary habits. The Delphi survey for the development of a questionnaire resulted in the first questionnaire of 31 items, the second one of 27 items, and the third one of 25 items. The validity of questionnaire items was tested with content validity ratios (CVR). The items whose CVR value was 0.29 or lower were eliminated or revised, because the minimum CVR value needed to test validity was 0.29. To test the reliability of questionnaire items, test-retest method was performed in 163 adults. According to the Kappa coefficient in the range of 0.314-0.716, all of the 25 items were in the reliability scope. A survey was taken with 702 adults to finally revise and supplement the third questionnaire whose validity and reliability were tested. Conclusions: Through those processes, a questionnaire for adults' dietary habit survey was finally completed. The significance of the study lies in the development of the first questionnaire on dietary habits equipped with both validity and reliability in South Korea.

  • This study aims to improve the Korean Farmers' Occupational Disease and Injury Survey (KFODIS), using the questionnaire improvement model, and systematic appraisal tools. The questionnaire improvement model comprises three stages: pretesting, redesign, and field-testing. The survey was evaluated by 13 expert reviewers, using a modified version of the Questionnaire Appraisal System (QAS-99). Based on the results of pretesting, survey questions were modified at a group meeting of experts. To identify potential issues with the improved survey questions, data were collected from 20 interviews and 31 respondents before behavior coding analysis was conducted. The questionnaire improvement model and systematic appraisal tools were useful in identifying, evaluating, and correcting miscommunication and other similar issues in the KFODIS.

  • The purpose of this study was to compare the difference of two survey methods for health services research. Data were collected by means of two types of household survey conducted from March 11 to September 19, 1985. A probability sample of 30,613 persons was taken from 180 Enumerated Districts designated by the Economic Planning Board. The sample was divided into two groups systematically. One group was surveyed by the self-administered questionnaire and the other group was interviewed. Response rates were 81.4% and 90.6% respectively. The data were analysed by the ratio of the results of the self-administered survey to those of the interview survey. No difference was observed in sex, age, residence, or occupation between the two groups. However the respondents' characteristics were statistically different between the two groups. The major findings of this study are as follows : 1. The morbidity rate was 142.5 per 1,000 persons during the two week period by the self-administered questionnaire survey and 74.3 per 1,000 persons with the interview survey method. The ratio of the morbidity rate by the self-administered questionnaire to that by the interview was 1.92, and the difference between the two rates were due to the personal characteristics. 2. The out-patient utilization rate was 10.2 visits per person per year by the self-administered questionnaire survey and 5.4 by the interview survey, and the ratio was 1.89; the admission rate was 3.2 times per 100 persons per year by the self-administered questionnaire survey and 1.9 times by the interview survey, and the ratio was 1.68. Differences due to the sociodemographic characteristics were greater in the out-patient utilization rates than in the adimssion rates. 3. Percentages of effective medical care demand were 90.2% in the self-administered survey and 92.3% in the interview survey; the ratio was 0.98 which was less than that of the morbidity rate and medical care utilization. But, differences of effective medical care demand occurred in persons with no occupation, and aged or low educated respondents. 4. Respiratory illness had the highest frequency in the two survey methods. But there was a slight difference between the two survey methods in morbidity composition. 5. It was concluded that data collected by the interview survey were inclined to be underestimated and this problem can be corrected by a modified self-administered survey.

  • Purpose: This study aimed to develop a questionnaire for the diagnosis of chronic fatigue syndrome (CFS) designed based on the systematic exertion intolerance disorder (SEID) criteria, and to validate the reliability of the questionnaire. Methods: A literature search on questionnaires for CFS diagnosis was conducted to develop a SEID questionnaire (SEID-Q27), followed by a pilot survey to identify the reliability of the questionnaire. Adults (Daejeon university personnel) with a Chalder fatigue scale (CFQ) score ≥15 were invited for the survey. We commenced the survey in November 2019 with a two weeks of interval for the test and retest method. The reliability of the questionnaire was investigated in three angles: 1. Cronbach's α, 2. correlations (r) of the questions, numerical rating scale (NRS), and visual analog scale (VAS), and 3. kappa (k) analysis. Results: Among the total 275 adults registered, 55 (20%) participants with a CFQ score ≥15 were invited, and 31 (11%) [15 male, 16 female] completed the questionnaire. The total Cronbach's α was 0.944 for the test and 0.949 for the retest. The reliability (r) of questions by CFQ score (≥15, ≥18, ≥20) ranged from 0.533-0.928 (p <0.05), and the r score of the NRS and VAS were the highest in CFQ scores ≥20, at 0.933 (p<0.001). The agreement rate of the SEID-Q27 between the test and retest was 87% (kappa k=0.743). Conclusions: The SEID-Q27 seems to be reliable. Further studies are needed to measure the validity of the tool and the cutoff point.
