This study validated and investigated the psychological properties of the Korean version of Everyday Ageism Scale to measure subtle ageism in day-to day lives. A total of 498 adults aged 60 and above participated in this study, which involved measuring the everyday ageism scale, experiences of elderly discrimination, self-perception of aging scale, depression (SCL-90R), and satisfaction with life scale. The sample was randomly divided into two groups.Tthe first group(n=198) used for exploratory factor analysis and reliability analysis, and the second group(n=300) was used for confirmatory factor analysis and validity testing. As a result, if was confirmed that K-EAS consist of 10 items and 3 dimensions (i.e., exposure to ageist messages, ageism in interpersonal interactions, and internalized ageism), consistent with the original scale. K-EAS demonstrated good internal consistency, convergent validity, discriminant validity, and incremental validity. In specific, ageism in interpersonal interactions and internalized ageism were correlated with experiences of elderly discrimination, negative self-perceptions of aging, and depression. However, ageism in interpersonal interactions and internalized ageism were negatively correlated with positive self-perceptions of aging and satisfaction with life. Also, the K-EAS provided additional explanation of depression even when excluding the effect of experiences of elderly discrimination. The result confirme that K-EAS is reliable and valid. The implication and limitations of this study, as well as suggestions for the use of K-EAS and future research, were discussed.

The purpose of this study is to verify the validity of KEDI Leadership Inventory (Simplified) for elementary and secondary school student. The existing Leadership Inventory is outdated by excessive or insufficient items. To verify reliability and validity of this KEDI Leadership Inventory (Simplified), we analyze internal consistency of scale for reliability and construct validity, convergent and discriminative validity. criterion-related validity. The internal consistency of the scale is relatively high from .610 to .838 for elementary school student, and from .734 to .936 for secondary school student To verify construct validity, we analyze a confirmatory factor analysis using AMOS whether revealed that the structural equation model including 5 construct validity in KEDI Leadership Inventory(Simplified) showed fit index at a satisfactory level as follows. The major fit indexes are showed as follows; CFI (.954), TLI (.943), RMSEA (.068) in the scale for elementary school student, CFI (.935), TLI (.915), RMSEA (.070) in the scale for secondary school student. Futhermore, to secure criterion-related validity, this KEDI Leadership Inventory(Simplified) showed significant correlations with student's leader position in their classroom for r=.358 (p<.01), and gifted education students are significantly higher .50 than no gifted student. This KEDI Leadership Inventory (Sim'plified) is made up of parsimonious 20 items, so that teachers can be convenient to identify intra-inter personal leadership characteristics of a student and recommend the student for gifted education institution.

This study aims to develop items to diagnose pre-service physics teachers' understanding of the conceptual knowledge of modern physics, based on the achievement criteria presented in the 2015 revised national science curriculum, and to identify the validity and reliability of the newly developed items. Data were collected from 467 pre-service physics teachers in the Physical Education Department or Science Education Department (Physics Education Major) of 15 universities across the nation. In this study the content validity, substantive validity, the internal structure validity, generalization validity, and the external validity proposed by Messick (1995) were examined by various statistical tests. The results of the MNSQ analysis showed that there was no nonconformity in the 23 items. The internal structure validity was confirmed by the standardized residual variance analysis, which shows that the 22 items was unidimensional. The generalization validity was confirmed by differential item functioning (DIF) analysis about groups lectured or not modern physics/quantum mechanics. In addition, item analysis and test analysis based on classical test theory were performed. The mean item difficulty is 0.66, mean item discrimination is 0.47 and mean point biserial coefficient obtained was 0.41. These results for item parameters satisfied the criteria respectively. The reliability of the internal consistency of the KR-20 is 0.77 and the Ferguson's delta obtained was δ = 0.972. By Rasch model analysis, the item difficulty (item measures) was discussed.

As the attitudes toward women is ambivalent (both hostile and ambivalent), people have a tendency to have ambivalent attitudes toward men. Despite conflicts between men and women caused by misogyny and misogyny have recently worsened in a Korean society, most of previous Korean studies have focused on the attitudes toward women. In addition, there has been no scale to measure such ambivalent attitudes toward men in Korea. Therefore, this study was designed to translate and validate the Ambivalence toward Men Inventory, a scale developed and currently utilized in the United State. Sample 1 (183 college students), sample 2 (300 college students), and sample 3 (317 adults) were used. Exploratory and confirmatory factor analyses resulted in 16 items and 2 factors. The tests of convergent and concurrent validity revealed strong evidence for the validity of the Korean version of the Ambivalence toward Men Inventory and the reliabilities of the two factors were .830~.917.

The purpose of this study was to develop the instruments which can measure behavior characteristics as a component of Mathematically Giftedness with in middle school period. This study prescribed the variable factors of measurement after classify the characteristics of Mathematically Giftedness through literature studies. And it produced instruments those are finally composed of 51 items through the preliminary test. The participants for the study were 424 Korean middle school students. Statistical analyses were carried out to verify the validities and reliability. Reliability(Cronbach $\alpha$) was in behavior characteristics, .95. Content validity was found to be satisfactory by internal validity evaluation on the test items. Internal validity were analyzed by BIGSTEPTS based on Rasch's 1-parameter item-response model. Construct validity was also found to be satisfactory through factor analysis which showed the four factors which the identification instruments were intended to measure such as, General mathematical mental ability, Mathematical Ability, Processing and Obtaining mathematical information Anility and Mathematical Disposition Ability. In conclusion, the instruments about behavior characteristics of Mathematically Giftedness during middle school period developed by this study are highly reliable on its reliability and validity.

The development process from creative potential to realized talent is complex and non-linear. This feature of the process stands out more in the process of living a creative life in the long-term rather than in a situation to solve certain problems in the short-term. The purpose of this study is to develop Creativity Path Inventory (CPI) for undergraduate students based on Sawyer's Zigzag Model which is one of creative process theories and to verify reliability and validity of the inventory. Thus, reflecting the characteristics of each stage of the model, this study developed 88 items in 8 factors and finally confirmed 38 items in 7 factors through item analysis and verification process on construct validity. Internal consistency of a total of 38 items in CPI turned out to be .835, confirming the reliability of the inventory and goodness-of-fit index of the final model also demonstrated an appropriate result. CPI with verified reliability and validity will help enable people who want to manifest creativity in view of everyday creativity to realize self-improvement by self-reporting their strengths and weaknesses on their own.

This study aims to develop a scale to measure the elderly's intention on home renovation and to verify its validity. As a methodological study based on the theory of planned behavior, this study provides 26 preliminary items in the pre-test. The first main test, performed to verify the content validity of the developed items, was followed by a second test of construct validity and reliability. As the result of the content validity test targeting experts, some of the original 26 items were excluded, while others were combined for a total of 22. As the result of the construct validity test of the scale, targeting the elderly aged 65 and over, the 22 items were narrowed down to 14 items, excluding the items that were unsuitable for communality and Eigen value. After once more conducting a factor analysis, the items were classified into five factors with a total cumulative variance of 72.5% and a Cronbach's α of 0.75. This study will contribute to the discussion of housing for the elderly by giving force to environmental regeneration activities through facilitating the identification of the home owners' intentions to renovate in order to improve the physical environment in decayed areas at a public level.

This study was to develop the fun perception scale measuring what conditions employees experience fun feeling in work and to examine the construct validity of it. For this, the pre-studies(open-ended questionnaire, in-depth interviews, literature survey, pre-survey) were conducted to develop the preliminary questions of fun scale. In main study, 250 employees(male: 125, female, 125) were responded to a questionnaire consisted of 40 questions of fun perception scale extracted by pre-studies. The results were as follow. First, through the item analysis, factor analysis and reliability analysis, 7 factors composed of 29 items were extracted: 'self-determination', 'extrinsic reward', 'goal achievement', 'pleasure in the process', 'contribution to the company', 'worthless', 'challenge'. Cronbach's alpha reliability coefficient of each factor was suitable. Secondly, EFA was conducted to test the construct validity of fun scale with AMOS 16.0. Several goodness of fit indexes were used to assess model fit: X2/df, TLI, CFI, RMSEA. The results were revealed that all the indexes were acceptable with no additional modification. Based on these findings, the theoretical and the practical implications of fun perception scale were discussed.

The purpose of this study is to validate the Play Participation Attitude Scale for parents of preschoolers, which was developed by the Delphi survey. 447 parents of 9 daycare centers in Seoul and Incheon were recruited for this study and, finally, data from 339 parents were used to perform exploratory factor analysis, confirmatory factor analysis, correlation analysis, multiple regression analysis, and reliability analysis. The results of the study are as follows. First, factor analyses revealed that the global fit of the sensitively play (7 items), responsively play (6 items), and delightfully play(7 items) three-factor model was good. Second, the internal consistency of the Play Participation Attitude Scale was good. Third, there was a statistically significant positive correlation between the current scale and the parents' playfulness scale, indicating concurrent validity. Finally, higher scores of the Play Participation Attitude Scale and its three factors significantly predicted lower scores of parenting stress and higher scores of the preschoolers' self-control ability. These findings revealed that this new measure to be both valid and reliable and specifically suggests what kind of attitude is appropriate for parents to adopt when participating in preschoolers' play.
