  • 본 연구는 초등 고학년 아동의 과일과 채소 섭취 수준 측정을 위한 간단한 식품 섭취 빈도 조사지를 개발 및 평가하고자 실시되었다. 2001년도 국민건강영양조사에 참가한 만 $9{\sim}11$세 아동의 24-시간 회상 자료에 기초하여 식품섭취빈도 조사지의 항목 선정을 위한 기초 조사를 하였다. 각 과일과 채소 식품의 일일 평균 섭취량을 전체 아동 및 섭취량의 4분위 집단 별로 산출한 후, 이 자료를 바탕으로 전체 인구 집단의 섭취량을 대변할 수 있을 뿐만 아내라 고 섭취군과 저 섭취군 간의 차이도 나타낼 수 있는 항목을 선정하였다. 총 9개의 과일 항목과 11개의 채소 항목이 식품 섭취 빈도지에 포함되도록 선정되었으며, 섭취 빈도에 대한 응답 항목은 지난 7일 간의 섭취에 대하여 1개의 선택 범주가 제시되었다. 개발된 조사지의 신뢰도와 상대적 타당도에 대한 평가는 서울에 위치한 한 공립 초등학교에 재학 중인 153명의 $4{\sim}6$학년 학생들을 대상으로 실시하였다. 한 달간의 간격을 두고 2회에 걸쳐 조사를 실시한 자료를 이용하여 검사-재검사 신뢰도를 평가하였으며, 두 번째 방문 시에 28개의 과일 및 채소 항목을 추가로 포함하고 있는 식품섭취빈도 조사지를 더불어 실시한 자료를 바탕으로 상대적 타당도를 평가하였다. 상관 분석과 항목 별 빈도 응답 및 섭취 수준에 따른 집단내 순위 분류의 일관성에 대한 분석을 실시한 결과, 본 연구에서 개발된 20개 항목의 과일 채소 식품 섭취빈도 조사지의 신뢰도와 상대적 타당도가 적정 수준 이상으로 나타났다. 신뢰도를 살펴보기 위한 개별 항목 및 과일, 채소, 과일+채소 섭취 빈도에 대한 상관계수는 $0.22{\sim}0.64$(p<0.001)이었으며, 항목별 빈도 응답의 일관도는 평균 69.3%(<=1 빈도 응답차이)와 81.3%(<=2 빈도 응답 차이)로 나타났다. 상대적 타당도를 살펴보기 위한 과일, 채소, 과일+채소 섭취 빈도에 대한 상관계수는 $0.91{\sim}0.93$(p<0.0001)로 높게 나타났다. 따라서 본 연구를 통하여 개발된 식품섭취빈도 조사지는 초등고학년 아동의 과일채소 섭취 수준을 간단히 심사하거나 평가하는 도구로서 유용하리라 사료된다.

  • The purpose of this study was to examine the reliability and validity of Stroke Impact Scale 3.0 (SIS 3.0). Here, the SIS 3.0 was completed by 154 stroke patients (mean = 62.7; standard deviation [SD] = 9.43). Construct validity was verified by analyzing the correlation between SIS 3.0 sub-domains, and convergent validity was investigated by analyzing the correlation between the Modified Barthel Index (MBI) and the Mini-Mental State Examination-Korean (K-MMSE) version. The characteristics of each item were analyzed by internal consistency and item discrimination based on the classical item theory. Construct and convergent validity were verified through this study. Although the item i included in the emotion domain showed low item discrimination, all but this item showed high discrimination. Internal consistency was also high in all sub-domains.

  • The purpose of this study is to develop and validate Inventory of Peer Relation for middle and high school students. First of all, in Study 1, 113 preliminary test questions were developed after reviewing of precedent studies in order to develop the Inventory of Peer Relation for Middle and High School Students. In Study 2, for the factor analysis, the survey was conducted for 600 students in three middle schools and three high schools in Busan to develop a final test, and finally 42 questions of them were selected. In Study 3, correlation analysis with another two inventories of peer relation was conducted to validate the developed Inventory of Peer Relation. The Inventory of Peer Relation developed through this study can be said reliable and valid. We made some suggestions for future studies.

  • The purpose of this study was to test the validity and reliability of the Korean version of the Tuberculosis Interview Instrument (K-TII). The instrument was first translated into Korean, back-translated to English, and reviewed. After the translation process, the instrument was revised from 52 items to 37 items by researchers and an expert according to the systematic review. In addition, these items were reduced to 32 items after the content validity test was done by 9 experts. As a result of pilot study conducted in 20 early childhood teachers, 32 items were selected for the preliminary instrument. Data collected from 289 early childhood teachers were used to test the validity and reliability of the preliminary instrument. The result of factor analysis showed that the instrument categorized into 7 factors explaining 71% of the total variance and 27 items were retained for the final instrument. The result of Cronbach's ${\alpha}$ coefficient was .88. In conclusion, the K-TII may be a suitable instrument for assessing tuberculosis prevention behaviors in early childhood teachers in Korea.

  • Objective : The purpose of this study to create a translation of Life Space Assessment(LSA) for elderly, which was then tested for content related validity and understanding test. Methods : The translation and content validation process involved direct and backward translation, and the collection of content-related evidence from 6 expert panels and 13 clinician panels. A content validity indices (CVI), means, and standard deviations were used for the analysis of the content validity. Results : The results of the comparison between the original LSA and the Korean LSA with the expert panels were I-CVI showed a very high value of .93. and 1.00, and S-CVI/Ave 0.99. The results of the understanding test were showed a very high value of .92 and 1.00, and S-CVI/Ave 0.97. Conclusion : Korean LSA showed content related validity and understanding test, and illustrated the applicability of LSA in a Korean clinical setting. The results showed LSA can be used a useful tool for evaluating the community mobility of elderly.

  • Regarding the growing concern for the mixture of landline and web-based/mobile survey, researchers are increasingly interested in methodological examination of anticipated benefits and problems of mixed mode surveys. This study focuses on scale construction. Multiple questions with a multi-point scale have been preferred in traditional surveys. However, it is not obvious if those scales have advantages also in a web-based survey. We tested if, in a web-based survey, validity, reliability, and easiness of response differ according to the size of scales.

  • The purpose of this study was designed to develop an questionnaire for healthy aging. The subjects of this study were total 335 people who participated in regular exercise and went to welfare centers in Seoul. The validity and reliability were tested for verifying the developed questionnaire for healthy aging. The data were collected between June 12, 2006 and October 27, 2006. The mean, standard deviation, kurtosis, skewness, reliability, exploratory factor analysis and confirmatory factor were analyzed for statistical purpose using by SPSS-Win 12.0 program. The results were as follows; First, to obtain content validity, the results of previous research and the value system responses were submitted to a judgement group. Second, the results of the factor analysis of the 20 items making up the questionnaire were classified into the following 3 factors; physiological health(6 items), cognitive-mental health(6 items), social-support health(8 items). Third, the reliability of the questionnaire for healthy aging was 0.891(Cronbach's alpha). In the factor analysis Cronbach's alpha correlations for the 4 factors ranged from 0.642 to 0.885. Fourth, the results of confirmatory factor analysis, all the index values(NFI, RFI, CFI, Delta 2 IFI) were close to 1. Thus, this questionnaire demonstrated good reliability and validity and therefore it was an appropriate measurement of healthy aging.

  • This study is to develop and validate the academic motivation scale for medical students(AMSMS) based on self-determination theory. After composing preliminary questions from 74 students, a preliminary and main survey were conducted with 148 and 300 students from September to November 2020. Factor analysis, reliability analysis, and correlation analysis were used. As a result of exploratory and confirmatory factor analysis, construct validity was verified. The fitness index of the five-factor model of amotivation, external regulation, introjected regulation, identified regulation, intrinsic motivation was good. The reliability of each factor was ranged from 0.760 to 0.933. The criterion validity of AMSMS was verified by showing a correlation with academic self-efficacy and school life satisfaction. This results show that the AMSMS is both valid and reliable, and it is expected to be used in research related to academic motivation of medical students in the future.

  • This study aimed to develop the short-form of age-friendly scale which was suitable for the Korean cities and to examine the validity. To develop the scale, WHO and Seoul welfare foundation's age-friendly city guide were compared and analyzed. The data for this study were collected on people aged over 55 years old living in Seoul. The results in exploratory factor analysis showed that seven-factor structure model was appropriate for the scale. Seven factors were outdoor amenity, transportation, leisure activity, social participation, social communication, health and welfare service, social exclusion. The results supported the construct and concurrent validity of the age-friendly scale. Also its good internal consistency was confirmed. The implication and limitation of the study and suggestions for the future studies were discussed.
