As a step preliminary to the factor-analysis of a child-rearing attitude scale under construction, its preliminary form containing a total of 368 self-answered questions was administerd to 88 married women with one or more children in the grade school age. all graduates of colleges and in possession of a home telephone and a house, twice from one week apart. The test-retest correlation coefficients, calculated for each test item based on the subject's choice among the three response alternatives on two test ocasions, ranged from .80 to .10. The cut-off point of r=.41 or lower led to the elimination of 48 items. As a point of incidental interest, the rate of response concordance. The namber of subjects giving the same categroy response on two occasions was calculated for each item and it was correlated with its test. retest correlation coefficient. The two different indices of item test-retest reliability were found not related to each other. Empirical evidence, as well as rational justifications, was presented to show that the correlation coefficient is the better of the tow indices of item test-retest reliability.

In this study, both the literary survey as well as empirical research has been executed to test the validity of the scales that measure the construct of self-monitoring scale could not be classified into five factors as Snyder suggested. Many other scholars (Briggs, Cheek and Buss, 1980) suggested 3 different classifications which was accepted by Snyder and Gangestad (1986). John, Cheek and Klohnen (1996) claimed a two-factor classification. As has been discussed, factor analysis is used to prove convergent validity within the factor and discriminant validity between the factors. However, depending on the researchers, many variations in classification of the factors were found and a lack of content and discriminant validity was found in the previous research findings. It is also important to note that Snyder's self-monitoring scale, did not factor-load at over 30 for all 25 items, regardless of how many factors could be classified. According to findings of this study, the self-monitoring scale neither classified as five, three or two factors nor factor loaded as hypothesized. It is also clear that Snyder's self-monitoring scale lack convergent validity as the sub-factors of the scale fail to prove its uni-dimensionality. The A self-monitoring scale not only fail to overcome the problems of Snyder's self-monitoring scale but even lost the attractiveness of the self-monitoring scale. In this study, it was also found that the A self-monitoring scale was not classified as hypothesized in either in a two or three-factor classification. It is, of course, not desirable to use any scale that lacks convergent and discriminant validity even though it has been widely used but also has held a great deal of influence on the field of social psychology. To overcome the shortcomings of Snyder's self-monitoring scale, Lennox and Wolfe(1984) suggested 13 items. This study 1. was dedicated to test the validity and reliability of the scale, in which we found that the data presented in validity as the two factors were classified and loaded as expected. Reliability was also proven by checking Cronbach's alpha for each factor and for the total items. In addition, a confirmatory factor analysis was executed for the 13 items using LISREL 8.12 program to confirm convergent validity in a two-factor classification. The model was fitting and sound ; however, the self-monitoring scale was unfitted and not validated. Thus, it is recommended to use not the original or the abbreviated self-monitoring scale but the 13 items in future studies. It should also be noted that items 7 and 13 should be removed to obtain better uni-dimensionality for the 13 items. These items loaded at over .30, too high for the two factors in the test results of factor analysis. In addition, it is necessary to double-check the cause of two-hold loading at over .30 for the two factors. It could be a problem caused by data or by the scale itself. Therefore, additional studies should follow to better clarify this matter.

본 연구의 3단계 선다형 평가 문항은 과학적 결과와 그 결과가 나온 과정 또 그러한 과정에 관계된 과학적 개념을 함께 물어 봄으로써 과학적 탐구 사고력을 의미있게 평가할 수 있고 객관식 문항형태이지만 객관식 평가의 단점인 추측의 요인을 주관식 응답에 준하여 거의 제거할 수 있다고 판단된다. 오랜 기간동안 1단계 4지선다형 또는 5지 선다형 시험에 익숙해 있던 학생들은 3단계 선다형 문항에 매우 적용하기 어렵겠고 교사들 또한 문항을 제작하는데 많은 시간과 노력이 필요하겠지만 평가가 학생들의 학습에 미치는 영향을 고려한다면 3단계 선다형 문항의 현장 도입은 절실히 필요하다. 이의 도입은 학생들의 탐구사고력의 신장에 큰 기여를 할 것으로 판단된다.

The purpose of this study was to develop the pattern drafting method which would be suitable to their physical characteristics for the fatty body of 40∼55 aged Korean women who are more than 1.5 Rohrer's Index and 90㎝ bust girth. The study was composed as follows; 1. Body measurement and statistical analysis: One hundred and thirty women were measured on 29 items. Thirty-four items including 29 measured items and 5 calcutated items were analyzed statistically. 1) Mean, standard deviation, variance, maximum, minimum, range were computed. 2) Correlation coefficients between each items were computed. 2. Development of new bodice pattern drafting method: Measurement items necessary to draft new bodice pattern were bust girth, center back waist length, shoulder width, back width, chest and neck base girth. The new pattern was examined through three wearing tests for completion. 3. Evaluation of the new pattern drafting method: The new pattern was objectively evaluated by the sensory test. The sensory evaluation was applied to evaluate the new pattern for the fatty body women by comparint it with the conventional patterns. The results of sensory tests of the new pattern are as follows: 1) The composite reliability coefficient is 0.7698, and the reliability of sensory test shows high. 2) According to a statistical analysis of the result of the 23 items on the questionaire, all the items showed significant differences(α 0.01) between the two, with the new pattern having higher scores. The new pattern is better conventional pattern as the average mark of the former is 3.901 but that of latter is 2.926. The new pattern drafting method proved to be superior to the conventional one especially in the fitness at the center front neck point, shoulder point, side line, armscye depth, position of bust point, chest width line, under arm dart and the shoulder line.

Purpose: Developmental care has been recognized as a very important component for the development and health promotion of preterm infants. However, research on how to assess developmental nursing competency has not been studied as expected. This study was done to develop and evaluate a new scale to measure nursing competency for developmental support of preterm infants. Methods: Concept analysis was done with using the Hybrid model of Schwartz-Barcott and Kim (2000), from which a preliminary new scale (30 items) was developed. To test the validity and reliability of the new scale being developed, data were collected from 122 NICU nurses at 4 hospitals in 3 cities in the Republic of Korea, from December, 2014 to March, 2015. Results: The final version of the Developmental Support Competency Scale for Nurses (DSCS-N) caring for premature infants was a 4-point Likert type scale, consisting of 19 items, and categorized as 6 factors, explaining 62.5% of the total variance. Each of the factors were named as follows; 'environmental support' (4 items), 'parental support' (3 items), 'interaction' (3 items), 'critical thinking' (3 items), 'professional development' (3 items), and 'partnership' (3 items). The Cronbach's ${\alpha}$ coefficient for the scale was .83 and the reliability of the subscales ranged from .60~.76. Conclusion: The psychometric evaluation of the new scale demonstrated an acceptable validity and reliability. Findings indicate that the DSCS-N can be used as the tool to test the effect of educational programs for nurses and contribute to advance developmental care for preterm infants.

Purpose: The purpose of this study was to develop and validate of a knowledge scale for lymphedema in patients with breast cancer. Methods: 34 preliminary items were made according to literature review, then verified content validity, construct validity, and reliability of the scale. 28 items among them were confirmed through content analysis by 4 experts. After a preliminary test, a survey for 156 breast cancer patients was performed for confirming construct validity and reliability. The data were analyzed using factor analysis, independent t-test, and KR-20. Results: This scale had 28 items consisting of 2 categories: prevention and self-care of lymphedema. Construct validity was confirmed by known-group technique because there were some categories consisted of just one or two items, and some mismatches between categories and items in factor analysis. Women who were educated about lymphedema scored significantly higher than women who had not (t=-3.92, p<.001). Reliability was appropriate (KR-20=.81). A percentage of correct answers was 74.6%, but it was from 31.8% to 96.1%. Conclusion: The study shows that this scale is reliable and valid to measure the knowledge of lymphedema. This scale can be effective to assess and educate the patients with breast cancer.

Purpose: The purpose of this study was to verify the validity and reliability of the Type D Scale-14 (DS14). Methods: The participants were 288 patients who were diagnosed with angina pectoris, myocardial infarction, and hypertension. DS14 was developed by Denollet(2005) and consists of two domains, 7 items on negative affectivity (NA) and 7 items on social inhibition (SI). The Korean version of DS14 was developed through translation-reversed translation and a preliminary test. Data were collected using a self-report questionnaire. Cronbach $\alpha$ and Guttman split-half were used to test reliability and item analysis and factor analysis for validity. The SPSS program was used. Results: 35.8% of the participants were classified as Type D. Mean score for NA was 16.80 and for SI, 14.10 in Type D participants. For reliability of NA, Cronbach $\alpha$=0.771, and for SI, 0.707. Factor analysis on 12 items(numbers 1 & 3 were excluded as the corrected item-total correlations were below r=0.3) yielded two factors for NA (6 items) and SI (6 items). Number 7 in the NA domain was sorted into the SI domain. Conclusion: The results indicate, the cultural differences were between Europeans and Koreans. Repetition of the research is needed for generalization of DS14.

Purpose: The purpose of this study was to develop an instrument of task performance evaluation for clinical nurses, thus testing the validity and the reliability of the scale. Method: Data was collected from 84 Head Nurses and 255 General Nurses. A conceptual framework, composed of 4 factors of meaning in task performance evaluation, was identified through review of the relevant literature. A total of 78 items were developed and were used on a five-point likert scale. Through factor analysis, items whose factor loading was below 0.50 were deleted, thus 35 items remained. To test the validity and reliability of the instrument, the SPSS 11.0 windows program was used. Result: The results of the factor analysis indicated that 4 factors were classified and the cumulative percent of variance was 67.54%. The results of the reliability test indicated that Cronbach's coefficient of the total 35 items was over 0.9176. The results of the factor analysis indicated that factor loadings of all items was over 0.50. Conclusively, the validity and the reliability of the scale were proven. Conclusion: This study was identified as a tool with a high degree of reliability and validity.
