  • 측정도구의 구조타당도는 내용타당도 이후 가장 먼저 수행되어야 할 측정 속성이다. 이를 위해 국내 간호학에서는 주로 CFA를 사용하는데, CFA로 얻을 수 없는 정보들을 제시하는 IRT/라쉬 분석도 같이 적용해 볼 것을 추천한다. 구조타당도 이외에 내적일관성 및 교차문화타당도/측정동일성 또한 측정도구의 내적구조를 확인하기 위한 것이다. 국내 간호학 측정도구 연구에서 교차문화타당도/측정동일성에 대한 검증은 거의 찾아볼 수 없는 상황이다. 따라서 앞으로는 이에 대한 평가도 시행되기를 바란다.

  • Objective : To translate and adapt the Social Appearance Anxiety Scale into Korean and validate the Korean version of the social appearance anxiety scale, which measures the fear and anxiety about being negatively evaluated by others based on one's overall appearance, including body shape. Methods : For item translation and adaptation, six bilingual translators participated in the process of forward-adaptation and back-adaptation. Data were collected from undergraduate students. The sample size is 105 for Study 1 and 212 for Study 2. Classical item discrimination and difficulty analyses, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and reliability analysis were performed. Results : A unidimensional structure was found with a high internal consistency (Cronbach's α=0.95) and a high test-retest reliability (r=0.918). In addition, the concurrent validity was examined by correlations of the scale and several other scales measuring constructs related to social appearance anxiety. Conclusion : K-SAAS appears to be a reliable and valid scale for screening and assessing social appearance anxiety.

  • The purpose of this study was to verify the reliability and validity of the Rosenbaum self-control schedule (SCS) for assessing resourcefulness in Korea and to explore the simplified scale. The study subjects consisted of 787 adults in a community. The data was collected during the period from Oct. to Dec., 1995 and analyzed as Cronbach α, item correlation with total, Pearson correlation and factor analysis with varimax rotation using SAS. Results were as follows : The mean SCS score for this sample was 17.2 and there were statistical differences for gender(men, 13.1 ; women, 20.0) on the SCS scores. The cronbachα of SCS with 36 items was .74 and when simplified with 30 items, it's coefficient alpha was .78. The translated content of the SCS was validated by two nursing faculty members and one professor of psychology. Factor analysis revealed the most parsimonious structure was obtained when six factors were extracted and subsequently rotated via the varimax criterion. There was 40.2% of total communality variance in the SCS with 36 items. The total communality variance was slightly increased to 43.4% with 30 items of the SCS. In order to reduce from 36 items to 30 items, the process excepted 6 items having low item correlation with total and low MSA(means of sampling adequacy) of factor analysis. According to factor analysis, there are six factors such as emotion control, impulse control, self-efficacy, coping with problems, pain control and satisfaction control, The SCS was found to have low, but statistically significant, correlations with social desirability and helplessness. From the above results, it can be concluded that the reliability of the SCS(inherent and simplified) was a acceptable level and its validity was reasonable when comparing it with other validity studies. To determine the usefulness the simplified scale, further study is necessary to simultaneously compare and analyze both scales for stability.

  • The purpose of this study was to develop a Quality of Life(QOL) scale for breast cancer patients in Korea and to test the validity and reliability of the instrument. To achieve the purpose of the study, a questionnaire was developed to interview 10 breast cancer patients and distributed to 155 patients with breast cancer in Korea. For data analysis, SPSS WIN 8.0/PC were used. Item analysis and factor analysis were carried out to test validity of the QOL scale. Cronbach's ${\alpha}$ and Guttman split half coefficient were used to test reliability of the scale. The results were as follows; As a result of the item analysis, 27 items were selected from the total of 34 items. 6 factors were selected by factor analysis. Six factors were labeled as 'response to cancer diagnosis and treatment', 'family well-being', 'physical concerns', 'psychological well-being', 'spiritual well-being', and 'economic concerns'. Six factors were explained by 72.236% out of the total variance. The first factor explained 20.738% and the second factor explained 16.593%, which were major factors for Korean breast cancer patients. Chronbach's ${\alpha}$ coefficient of the tool was .9120, and Guttman split-half coefficient was .8148. The scale was identified to be a tool with a high degree of reliability and validity. Therefore, this scale can be effectively utilized for assessment of Quality of Life of patients with breast cancer in Korea.

  • The purpose of this research is to understand the levels of crisis and quality of life and the relationship between them. Data was collected from questionnaires completed by 384 middle-aged women between 40 and 59 years old. The sense of crisis was measured by a scale which was developed by Kim(1988) and modified by Oh(1999). The quality of life was measured by the scale which was developed by Noh(1988). The data was analyzed using the SPSS (Statistical Package for the Social Sciences) program and included: descriptive statistics, Pearson correlation, and stepwise regression. The results of this study were as follows: 1) In the sense of crisis scale, 'experiencing emptiness and powerlessness through my friends is the highest item($3.56{\pm}1.06$). 'Meaninglessness in daily living' factor's score is $3.16{\pm}0.76$ and another factor, 'concept of my life thus far' score is $2.89{\pm}0.74$. Then the former is higher than the latter. 2) In the quality of life, 'eat well now' is the highest item($3.60{\pm}0.93$). 'self-esteem' is the highest factor($3.37{\pm}0.62$) and 'emotional state' is the lowest factor($2.89{\pm}0.31$). 3) According to the correlation between factors of crisis and quality of life, there was a significant negative correlation between two factors of crisis and five factors of quality of life except emotional state. 4) According to linear regression, two factors of the sense of crisis showed the explanatory power of the quality of life with 31.6%. On the basis of above findings, the following is suggested; Crisis is not precipitated by special events and new accidents, but the normal emotional change phenomena process in the human life cycle. As a result, we should develop the nursing programs and education programs about crisis intervention for middle-aged women's health.

  • The purpose of this study is to improve the fitness of clothes by producing patterns considering body proportions at a time of producing clothes for export through extracting factors comprising body types and conducting comparative analysis of proportions by body part using body indexes of Korean women in their 20s living in both Korea and foreign countries. The study results are as follows. Factor analysis by group was conducted for body indexes in order to examine body types of Koreans living overseas. As a results, six factors were extracted from all of three groups; Joseonjok(Koreans living in China), Goryeoin(Koreans living in Russia) and Korean residents in Japan, and their explanatory powers were 60.42%, 63.62%, 63.15%, respectively. Obesity factor was extracted as the 1st factor, and the groups showed differences in other factors. As a result of proportion comparison using body indexes of Koreans living in foreign countries and Korea, it was found that, in height item, when regarding the height as 100, the length of the lower part of the body was long in the order of Goryeoin. Joseonjok, Koreans living in Korea and Korean residents in Japan. Also in width item, when regarding the waist as a standard, it was observed that Joseonjok people have the shoulders, the breasts and the hips that look relatively wider comparing with the width of the waists because they have very narrow waists and the width between shoulder length is big. In addition, the study examined proportions of the breast thickness/the breast width, the waist thickness/the waist width, the hip thickness/the hip width to height. From the analysis, it was found that breasts of Koreans living in Korea are flattest while their waists are slender, and Goryeoin and Joseonjok have round body shapes from the waist to the breast.

  • Purpose: The purpose of this study was to confirm the factor structure of the McGill Quality of Life Questionnaire-Revised (MQOL-R) in the context of Korean culture and to verify its reliability and validity. Methods: The participants comprised terminal cancer patients aged 25 or older, and data from 164 participants were analyzed. The study was conducted in the following order: translation, expert review, reverse translation, preliminary investigation and interviews, and completion of the final version. Confirmatory factor analysis was applied to evaluate the validity of the instrument, and the Beck Depression Inventory, Korean version (K-BDI) was applied to confirm the criterion validity of the MQOL-R Korean version. The Cronbach's alpha coefficient, representing internal consistency, was measured to evaluate reliability. Results: Cronbach's alpha for all 14 questions was 0.862. The model fit indices for confirmatory factor analysis were within the acceptance criteria. The factor loadings of all four factors were over 0.50, and convergent validity and discriminant validity were confirmed. Regarding criterion validity, a negative correlation was found between the four factors of MQOL-R Korean version and the K-BDI. Conclusion: The MQOL-R Korean version, the reliability and validity of which were verified in this study, is a 15-item tool consisting of 14 items dealing with four physical, psychological, existential, and social factors and a single item evaluating the overall quality of life. The MQOL-R Korean version is an instrument that can more concisely and effectively measure the quality of life of patients with life-threatening diseases.
