The purpose of this study was to develop an instrument to measure family resilience for Korean families with a chronically ill child, and to test the validity and reliability of the instrument. Method: The items of instruments used based on the researchers' previous study of concept analysis of Korean family resilience. Nineteen item scales were developed with five domains. In order to test reliability and validity of the scale, data were collected from 231 families, who had a child with a chronic illness. Data was collected between August and September of 2001 in a 3rd level University Hospital in Seoul, Korea. Result: The results were as follows: As a result of the item analysis, 19 items were selected from the total of 37 items, excluding items with low correlation with the total scale. Five factors were evolved by factor analysis, which explained 56.4% of the total variance. The first factor 'Family strength' explained 28.5%, 2nd factor 'Family maturity' 8.7%, 3rd factor 'The ability to use of external resources' 7.0%, 4th factor 'Control' 6.6%, 5th factor 'The driving force for finance' 5.7%. The attributes in these factors were different with those identified by concept analysis of the family resilience in Korean families from the previous study. Cronbach's $\alpha$ coefficient of this scale was .8039 and Guttman spilt- half coefficient was .8184. Conclusion: The study support the reliability and validity of the scale. Because the main concept of family resilience was family strength, there were distinct differences in dimensions of family functioning scales.

Purpose: This study was done to develop and validate a measure to evaluate the Korean version of psychological insulin resistance (K-PIR) in patients with diabetes in Korea. Methods: Items were initially generated from literature reviews and interviews with 19 patients with diabetes. The content validity of the items was evaluated by experts. Participants were 424 patients with diabetes recruited through convenience sampling. A cross-sectional survey was designed for item-analysis, exploratory factor analysis with principal axis factoring, and confirmatory factor analysis. Cronbach's alpha was calculated to measure the internal consistency. Results: For the 24 items of the Korean version of psychological insulin resistance, six items were eliminated because of low correlation with the other items. Exploratory factor analysis with 18-item showed that two factors (psycho-cognitive factor and supportive factor) explained 41.8% of the variance, and the factor structure of K-PIR model had a good fit. Internal consistency of K-PIR with 18 items revealed good reliability. Conclusion: The findings show that the K-PIR is reliable for measuring the psychological resistance to insulin therapy for Korean patients with diabetes. However, further study is needed to evaluate the validation because the proportion of variation of K-PIR was low in this study.

Little is known about sexual autonomy in the light of human sexual health or sexual behavior. The purpose of this study was to increase understanding of sexual autonomy by developing a scale to measure sexual autonomy in college students. The measure was based on the perspective of human beings as having autonomy. A methodological developmental design was used. The study was done in three steps and included concept development through content analysis of relevant literature individual interviews using open-ended questions with 19 college students, item analysis of data from self report questionnaires for item to total correlation, content validity index by professionals and college students, and factor analysis with principal component analysis. Three groups participated in testing the measurement scale; Group A in 1998, a nationwide convenience sample of college students (n=1,163), Group B, college students in 1999 (n=233), and Group C, college students in 2000 who responded to the measurement scale before and after a sex education program (n=216). A series of exploratory and confirmatory factor analyses were conducted to test validity. For analysis of the questionnaires, statistical methods including reliability (test-retest), item to total analysis, content validity, factor analysis for construct validity and t-test for mean difference according to gender, sexual coitus, previous sex education, and pre-post experiment sex education were used with SPSS 10.0. Results: 1. Two stable factors were extracted and these contributed 48.05% of the variance in the total score. All 13 items loaded above .40 on each factor. 2. Factor I with 10 items was named 'control' and factor II with 3 items and was named 'coping'. 3. Differences in sexual autonomy scores for college students according to their experience showed that there were significantly higher scores for sexual autonomy in the post sex education group(t=-10.841, p=.000), but there were no differences according to whether or not they had previous sex education. Female college students had higher sexual autonomy scores than male college students in A or B group (t=-5.933, p=.000/ t=-1.992, p=.048). 4. Cronbach's $\alpha$ was .8603 for the total 13 items with 1,632 college students, .8739 with 232 students, .8333$\sim$.7647 with pre-post sex education with 216 students. This measurement was found to have a high validity and reliability for measuring sexual autonomy in college students. Therefore, the author recommends that it be used to measure the effects of sex education. It is suggested that further study is needed to analyze the relationship between sexual autonomy and sexual behavior.

The purpose of this study was to develop an appropriate scale for evaluating early years children's English textbooks and to confirm the validity and reliability for the scale thus developed. The scale was administered to 563 Korean early childhood English teachers. Exploratory Factor Analysis (EFA) of the 24 item scale demonstrated Cronbach' ${\alpha}$ = .94 for internal consistency of the total items. Confimatory Factor Analysis (CFA) supported a four-factor structure. Cross-Validation for the retest accepted the four-factors. Those four factors were as follows; Contents & Organization as factor 1, Illustrations & Designs as factor 2, Materials & Topics, as factor 3 and Objectives as factor 4. The author suggests that these afore mentioned factors will prove to be most useful for evaluating the children's English textbooks which are apparently published in an often quite indiscriminant manner.

Purpose: The purpose of this study was to develop a scale to measure person-centered critical care nursing and verify its reliability and validity. Methods: A total of 38 preliminary items on person-centered critical care nursing were selected using content validity analysis of and expert opinion on 72 candidate items derived through literature review and qualitative interviews. We conducted a questionnaire survey with 477 nurses who worked in intensive care units. The collected data were analyzed using exploratory factor analysis (EFA) and confirmative factor analysis (CFA) with SPSS and AMOS 24.0 program. Results: EFA was performed with principal axis factor analysis and Varimax rotation. The 15 items in 4 factors that accounted for 50.8% of the total variance were identified by deleting the items that were not meet the condition that the commonality should be .30 or more and the factor loading over .40. We named the factors as compassion, individuality, respect, and comfort, respectively. The correlation coefficient between this scale and the Caring Perception Scale was r=.57 (p<.001), which determined concurrent validity. The item-total correlation values ranged from .39 to .63, and the internal consistency for the scale was Cronbach's ${\alpha}=.84$. Conclusion: The reliability and validity of the 15 item person-centered critical care nursing scale were verified. It is expected that the use of this scale would expand person-centered care in critical care nursing.

Objectives : The purpose of this study was to develop an instrument for Korean Scaling Fear (KSF)-1.1 in scaling patients. Methods : 402 sample size for scaling patients was studied in Daegu city in July and August of 2011. Mean and standard deviation was calculated in 3 dimensions(FWS: fear while scaling, DDH: distrust on dental hygienist, FAS: fear after scaling). Results : Age of 402 subjects was 36.5 years. In analyzing reliability for item-level, a range of correlation coefficient(${\alpha}$) on item-internal consistency(FWS, DDH, and FAS) was 0.58~0.88(${\alpha}$=0.90), 0.40~0.71(${\alpha}$=0.82), and 0.54~0.63(${\alpha}$=0.82), respectively. Floor(%) and ceiling(%) value on 3 dimensions were also 9.2% and 4.0%, 12.4% and 0.5%, and 17.7% and 1.2%, respectively, therefore, we found statistically high reliability for those(p<0.001). With explanatory factor analysis, this study could generate 3 dimensions(factor 1, eigenvalue 5.41, proportion 0.49; factor 2, eigenvalue 1.50, proportion 0.14; factor 3, eigenvalue 1.04, proportion 0.09) and 11 sub-scales. Also confirmatory factor analysis results showed that the KSF1.1 model was fitted very well in analysis of model fit($x^2$=112.94, df=41, p=0.000; goodness of fit index=0.95; adjusted goodness of fit index=0.92; root mean square residual=0.057). Conclusions : In conclusion, The findings of this study showed that developed reliable and valid instrument for measuring the KSF1.1 in the scaling patients.
