This study was performed to develop a scale of maternal conflict based on already established scales and the literature review. The major purpose of this study was to develop a scale of which contains difficulties which mother can feel to rearing her child and can be applied to mothers at home or employed mothers. 68 items were developed. For content validity test, the items were examined by 7 experts panel with Likert 4 scale. The 39 items were selected as high validity from 86% of the experts. The item number of each area and the misunderstanding words were corrected by advices of experts. 10 mothers again examined 39 items in order to correct the misunderstanding words and the long sentences. For reliability and factor analysis of 39 items, 496 mothers participated. 34 items were chosen because 5 items that corrected item-total correlation coefficient were lower than 0.2 were excluded by the result of reliability analysis. Factor analysis was done with 34items. 6 factors were classified higher than eigen value 1.0, 28 items were chosen because 6 items that factor loadings were lower than 0.4 were excluded. These factors were named as employment and caring for child(6 items), child education(5 items), support system for caring for child(4 items), interaction with mother and child(4 items), view of maternal role(5 items) and me as human being(4 items). Reliability analysis was done with 28 items. 1 item(36 number of factor 1) was excluded because corrected item-total correlation coefficient were lower than 0.2. Therefore, 27 items were chosen. Maternal Conflict Scale was contained 27 items. The corrected item-total correlation coefficient of 27 items were ranged from .2345 to .5240 and Cronbach alpha coefficient of those was .8207 by the results of reliability analysis. It can be evaluated that this scale had a high validity and reliability because of passing through an objective process of test.

The purpose of this study was to develope a questionaire measuring clothing behavior of elementary school children. At first, after pretest, the clothing behavior questionaire consisted of 70 items which were devidad. into 7 subscales i.e. Clothing interest. Clothing satisfaction. Clothing management, Clothing sex-role. Clothing comfort. Clothing conformity. and Clothing independence. Each item was rated on a 3-point scale. Samples were 447 boys and girls (4 th, 5 th, 6 th grade) of three elementary schools in Seoul. Korea. The data were analyzed by item analysis and factor analysis. Factor analysis was useful in attempting to establish contruct validity. Item validity was examined based on the correlation coefficients and item discriminating power through the chi-square. Reliability was examined based on the Cronbach's Alpha Reliability Coefficient and test-retest method. With this analysis the subscales were reconstructed to following 6 factors. Clothing conformity items were not clustered by the factor analysis. 52 items of 6 factors selected by the analysis. The factors characteristics were as follows: 1. Clothing interest (10 items) 2. Clothing satisfaction (11 items) 3. Clothing management (8 items) 4. Clothing sex-role (12 items) 5. Clothing comfort (6 items) 6. Clothing independence (5 items)

Purpose: The purpose of this study was to develop a health conservation scale with high validity and reliability for institutionalized elderly. Method: The process of development of this scale was as follows. A conceptual framework composed of 4 phases of health conservation of institutionalized elderly was identified based on the literature review with elderlies and discussions with experts in health conservation. A total of 75 items, on a 4-point scale were developed. Through reliability testing and factor analysis, 57 preliminary items were selected. By means of internal consistency of the 57 items, 18 items whose inner-items correlation coefficient was below .40 were deleted. Through factor analysis, 2 items whose factor loading was below .40 were deleted. Finally 37 items remained. To verity the 37 items, factor analysis, reliability testing, and correlation was done. Data were collected from 207 institutionalized elderly subjects in Daegu, Kyungpook, Busan, and KyungNam Province from August. 2003 to February. 2004. Result: In the result of factor analysis of the 37 items, 4 factors were extracted. These factors were labeled as ‘personal integrity’, ‘conservation of energy', ‘structural integrity’, and ‘social integrity'. These factors included 4 phases of health conservation. Cronbach's Alpha of 37 the items was .9424 and the correlation coefficient of HPLP was .723. Conclusion: The researchers recommend the following: An explorative study on the variables related to health conservation is needed for criterion validity of this scale.

Purpose: The purpose of this study is a preliminary study to develop a comprehensive information avoidance scale that includes various search contexts. Research design, data and methodology: This study is a part of exploratory sequential design of mixed method for the development of information avoidance scale. Based on the themes derived from the analysis of the in-depth interview data collected in the qualitative research of the first stage of the study, 45 preliminary items on information search and avoidance were constructed. The factors related to information searching included information recognition, information seeking purpose, and information search expectations. Individual, information, time, and system factors were related to information avoidance. Pearson's correlation analysis was performed for the correlation between factor items, and Cronbach's alpha analysis was performed for the reliability analysis of the items. Exploratory factor analysis was applied to examine the construct validity of 35 items of information avoidance. Results: Among the information avoidance items, one of the less relevant among information purpose items, two information factor items, and one time factor item were excluded. Conclusions: A secondary survey should be conducted to confirm the validity and reliability of the scale composed of adjusted items (35) based on the results of exploratory factor analysis. The strength of this preliminary scale is that it was developed based on vivid qualitative data of ordinary people who had experiences of search and avoidance in various search contexts.

Postpartum depression is one of the most serious problems in maternal health because it affects not only the mother but also her family. Postpartum depression disturbs the maternal-infant interaction and attachment. However, most postpartum depression patients ignore this problem and do not seek treatment. Many clinicians and researchers realiza there is a need to develop a postpartum depression scale. Thus, this study has been designed to development of a postpartum depression scale. Data were collected through a survey over a period of three months. Subjects who participated in the study were 167 Korean mothers in their postpartum period. The author used a convenience sampling method. The analysis of the data was done with SPSS PC/sup ＋/ for descriptive statistics, item analysis and factor analysis. Initially 62 items were generated from the interview data of eight postpartum depression patients and from a literature review. This preliminary scale was analyzed for reliability and validity. The results of this analysis are as follows. 1. Initially 62 items were analyzed through the Index of Content Validity(CVI) and 48 items were selected. 2. Seven factors were extracted through the principal component analysis, and these contributed 61% of the variance in the total score. Finally 46 items in the scale loaded .41∼ .84 on one of seven factors. 3. Each factor was labeled. Factor 1 was labeled 'emotional phenomena-emotional upset' and included 13 items, factor 2 was labeled' cognitive phenomena-self concept disturbance' and included seven items, factor 3 was labeled 'relationship to baby-negative feeling' and included six items, factor 4 was labeled 'relationship to baby- overload' and included eight items, factor 5 was labeled 'negative maternal identity' and included five items, factor 6 was labeled 'biophysiological phenomena-disturbance of physical functioning' and included four items, and factor 7 was labeled' interpersonal relationship phenomena-blamed others' and included three items. 4. Cronbach Coefficient Alpha for internal consistency was .95 for the total 46 items. Finally, the author suggests that this scale could be adequately applied in assessing the postpartum depression of mothers during the postpartum period. The results of this study can contribute to designing an appropriate postpartum depression prevention strategy.

In this study, 'Instruments of the achievement attribution in mathematical learning' was develop to investigate the reasons of mathematical learning achievement by reflecting Korean middle school and high school students' psychological characters and learning context in mathematical learning. To develop the appropriate items for the achievement attribution in mathematical learning, after reviewing attribution literature thoroughly, first version of the instrument was developed and Exploratory Factor Analysis and Confirmatory Factor Analysis were conducted. Then, to reduce the effect of the gender difference and achievement level difference, Differential Item Functioning was performed. Also, using Multiple group Confirmatory Factor Analysis, this instrument was investigated to see whether this can be used for both middle school and high school. The final items for success attribution are 3 items for luck, 3 items for effort, 2 items for ability. The failure attribution were composed of 3 items for luck, 3 items for effort, 2 items for ability, and 2 items for other. The instrument was developed by using large samples and psychometric analysis. Therefore, mathematic teachers can use this instrument efficiently to make a foundation for better learning environment so students' cognitive area and affective area can be harmonized.

This study was performed to develope a scale of gender role identity in Korean adults based on the Bem's theory of androgyny. Although there were several tools in Korea, they were revealed having some problems of cultural differences, translation biases, and methodological problems. Methods: A list of 78 items were developed using the existing tools and descriptions from 5 married couples. The items were the typical personality characteristics which were manifested by gender, male or female. And the list contained several items which were the socially desirable personality characteristics. which would be simply used as contextual items. Validity of the 78 items were screened by 18 expert panels with 4 point Likert scale, and 57 items were judged as highly valid from 70% of the experts, which were selected as preliminary items for the tool. Using the preliminary tool which was developed as a 4 point Likert scale, data were collected from 1,127 subjects for item analysis and factor analysis. 53 items were remained, because 4 items whose item-total correlation were lower than 0.2 were excluded by the result of item analysis. Factor analysis was done with the 53 items, and 49 items whose factor loadings were same and higher than 0.4 were remained. 3 factors were identified with eigen value 2.0, and these factors were named as masculinity, femininity, and social desirability. Results and Conclusion: KGRII(Korean Gender Role Identity Inventory) which contained 45 items was developed, with 15 items for 3 factors. The reliability of the tool was very high. Cronbach alpha of the tool was 0.929, and alpha of the subscales were ranged from 0.841 to 0.922.
