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 study the middle and high school student’s value on the family life of the contemporary society. The data for this study has been collected for 808 students of kangwon-do by Liert-scale Type questionnaire. The data were processed by SPSS-X Program. Frequency, Percentage, Mean, Standard Deviation, One-way ANOVA, Pearson’r coefficient, Step-wise multiple regression and Cronbach’coefficient have been calculated and analyzed. The Summary of this research is described as follows. Firstly, the overall average of value of family life was 3.25 points which reflected more or less modern tendency. Secondly, significant difference in the student’s value of family life affected by environmental variables were such as sex(P<.001) school years(P<.001) group(P<.01). Thirdly, the overall average of the student’s interest in the home economics was 3.74 points which reflected heigher tendency, Significant difference in the student’s interest in the home economics according to environmental variables were such as sex(P<.001) school years(P<.05), living standard(P<.01), residential area(P<.001). Fourthly, the student’s overall interest in the home economics and their view on the family life were correlated as follows; Spare time(r=-1.3), parents-children(r=.12) relatives and neighbors(r=0.8) show lower correlation and household work(r=.07) show higher correlation. Fifthly, the area which has closest correlation with the value on the family life was the value on family economics, whereas is has been shown that the field with least correlation was the area of supporting the spare time. Sixthly changes that affect the student’s value of the family life were such as sex (${\beta}$=.43), school years(${\beta}$=.18), group(${\beta}$=.15) and interest degrees(${\beta}$=-.12). These whole explanatory power was 21%.

Nurse's caring behaviors are essential to help patients cope with their health problems. The purpose of this study was to investigate the importance of nurse's caring behaviors as perceived by staff nurses and patients. The subjects were 295 staff nurses and 340 patients from five medical centers in Taegu. Data collection was done from Dec. 10, 1997 to Jan. 31, 1998. The tool for this study was a 7 point Likert type scale with 27 earing behaviors developed by Lee(1996). Cronbach alpha of the tool was .9701 in staff nurses and .9618 in patients. Data were analyzed with SAS using t-test, ANOVA and Spearman rank correlation program. The results are as follows : 1. The a verage score of perceived importance of nurse's taring behaviors for the 27 items was 5.65 in staff nurses and 4.97 in patients. 2. The most important caring behaviors perceived by the nurses was 'Nurse gives painless and cautious injection and treatment for patients' and for the patients, 'Nurse gives hygienic treatment and nursing care'. 3. The caring behavior which showed a significant difference between the ranks of perceived importance by staff nurses and patients was 'to treat the patient with tenderness and friendship'. 4. The Spearman rank correlation coefficient between the ranks of importance perceived by staff nurses and patients was 0.8302. With the results of this study, the staff nurses could be recognized to have much enthusiasm and passion about caring. It is suggested that nurses let the public know about the nurses' caring roles. In the future, research to investigate the actual practice of nurses' caring behavior is necessary.

Objectives: This study aimed to develop and assess the content validity and internal consistency of a questionnaire on the feasibility of mobile dietary self-monitoring applications. Methods: We developed a feasibility questionnaire to assess the overall usage, convenience, usefulness, and satisfaction of mobile dietary applications. The initial draft of the questionnaire contained 17 items with yes/no, multiple-choice, and open-ended questions and 52 items on 5-point Likert scales. To validate the content, ten experts evaluated the relevance of the items for each subscale using a 5-point scale. We calculated the item-level content validity index (I-CVI) and scale-level content validity index (S-CVI). A total of 102 adults answered the questionnaires which reflected the experts' reviews. We conducted an exploratory factor analysis to determine the underlying structure of responses and categorized convenience, usefulness, and satisfaction. We also calculated Cronbach's alpha coefficient to examine the internal consistency of items in each subscale. Results: The S-CVI score of the items was 0.86, and we removed items with an I-CVI score of < 0.80. We combined, revised, or separated some remaining items and added one item as per the experts' comments. As a result, we included 16 items about overall usage and 42 sub-questions. Based on the responses of the 102 adults, we performed exploratory factor analysis using the principal axis method. We retained items with a factor loading of > 0.40, resulting in a final set of 35 questions (convenience: 15, usefulness: 12, satisfaction: 8 items). The Cronbach's alpha values of the three scales were 0.93, 0.91, and 0.91 for 1) usefulness, 2) convenience, and 3) satisfaction, respectively. Conclusions: We developed a feasibility questionnaire for mobile dietary self-monitoring applications and examined its content validity and internal consistency. Our questionnaire has the potential to measure the feasibility of mobile dietary self-monitoring applications.

This study was conducted to investigate purchasing behavior of jeans consumers and to find differences in jeans evaluative criteria according to consumers' characteristics. Male and female university students participated in the study. Quota sampling method was used to collect the data. Data from 492 questionnaires were used for the statistical analysis. Descriptive analysis, factor analysis, Cronbach's alpha coefficient, ANOVA, Duncan test, and t-test were conducted. Three factors of jeans evaluative criteria classified (i.e., external criteria, internal/aesthetic criteria, internal/quality criteria). Results indicated that most of respondents put on jeans wear more than three times per a week and 38.1% of respondents reported that they owned three to four jeans products on average. Department store was the most used place to buy jeans product with 44.2%. 27.5% of respondents spent from 50,000 won to 100,000 won on purchasing jeans. Style was the highest important jeans evaluative criterion with 36.2%, followed by fitness, price, color, condition of washing treatment. Women respondents considered aesthetic criteria and quality criteria more importantly than men did. Respondents who were on a high income and spent more than 200,000 won per a month on apparel more concerned aesthetic criteria and external criteria than the other respondents did. Results of this study provide a basis for understanding jeans consumers' purchase behavior and evaluative criteria.
