  • The purpose of this study was to develop and validate a job-esteem scale that reflects the unique characteristics of academic librarians. The study conducted an analysis of relevant literature and existing scales in the scale development phase, followed by in-depth interviews with 10 academic librarians, resulting in the creation of 100 preliminary measurement items. These items underwent content validity testing, consultations with linguists, and face validity assessments, which culminated in the selection of 52 items for a preliminary measurement scale. A pilot survey was then administered with 300 academic librarians from four-year universities nationwide to collect data, and item analysis and reliability testing were performed with the data. Then, an exploratory factor analysis was conducted, resulting in the elimination of 22 items and the finalization of 30 items. The main survey was conducted with 345 academic librarians, and the study confirmed high reliability of the data through item analysis and internal consistency tests. Through another confirmatory factor analysis, the study finalized 29 items. The final scale met all criteria for convergent, discriminant, and criterion validity. This study marks the first development of a job-esteem scale tailored to the distinct attributes of academic librarians, and its significance lies in its utility for assessing and analyzing the job esteem of academic librarians.

  • The purpose of this study was to translate and validate the Lesbian, Gay, and Bisexual Identity Scale(LGBIS), which is a scale measuring the multidimensional identities of sexual minorities. For this, we conducted an exploratory factor analysis using a sample of 201 LGBs(homosexuals and bisexuals). Identical to the original scale, eight factors were extracted from the translated scale(i.e., concealment motivation, identity uncertainty, internalized homonegativity, difficult process, acceptance concerns, identity superiority, identity centrality, and identity affirmation), but one item was removed. In addition, the reliability coefficients of the eight factors except for concealment Motivation were satisfactory. The Confirmatory factor analysis revealed that the 8-factor model had a good fit to the data. Finally, to verify the criterion validity, correlation among each eight factor and the scales measuring the identity related scale and the psychological-functioning scale were analyzed. In conclusion, the Korean version of the LGBIS consists of 8 factors and 26 items in total. Also it was found to be a valid measure for LGBS in Korea as well.

  • This study aimed to translate and validate the Positive and Negative Ex-Relationship Thoughts (PANERT), a scale measuring the positive and negative valence of thoughts about past relationships in early adulthood. For this purpose, PANERT was translated into Korean and the study surveyed on 337 single male and female adults in their 20. Then, the gender difference between major variables was analyzed. After going through item analysis, all twelve original items were used to construct the Korean version of PANERT. The confirmatory factor analysis(CFA) supported the two factors structure of the Korean version of PANERT: positive vs, negative thought content valence. Also, the reliability coefficients of each two factors were all satisfactory. As a result of a correlation analysis, the criterion-related validity of the two sub-factors was good with other related scales(Intrusive rumination scale of K-ERRI, K-DASS-21-D, and K-PANAS-Revised) except for changes of self-perception. Finally, the research model was built to examine the mediating effect of two affect responses(positive and negative) in the relationship between two thought content valences and depression. In this process, the convergence and discriminant validity of the Korean version of PANERT were confirmed and the indirect effect was also confirmed in the structural equation model. In conclusion, the Korean version of PANERT consists of two factors and twelve items in total. Also, it is a reliable and valid tool for measuring the thought content valences in the romantic relationship breakup experience of early adults.

  • The purpose of this study was to develop scale for the measurement of indirect traumatization occurred by social disaster and test their validity. To achieve this purpose, this study conduct a research through the following procedure. First, to develop the inventory, various responses of indirect traumatization occurred by social disaster were gathered from Korean adults participated in open questionnaire. 41 items were made. Second, exploratory factor analysis were performed and 21 items were selected in this step. The Indirect Trauma Scale of Social Disaster(ITSSD) consisted of 4 factors, each with 4-to-8 items, respectively. Four factors include ① private coping responses ② symptom responses ③ distrust responses of world ④ moral emotion cause of social perpetrators. Appropriate levels of reliability were established for the ITSSD. Third, Indirect Trauma Scale of Social Disaster was validated by confirmatory factor analysis, and 21 items were fixed. To 300 participants differed from development step, confirmatory factor analysis was performed. 4 factors structure derived from the exploratory analysis was appropriate. And 4 factors indicated reasonable fit index such as TLI(.913), CFI (.924) and RMSEA(.077). In addition, ITSSD identified a significant positive correlation with Posttrauma Risk Checklist, Korean Depression Scale, State-Trait Anxiety Inventory-KYZ and negative with Acceptance-action Questionnaire-2. But that was unrelated to Forgiveness Trait Scale and Life Satisfaction Scale. Also the result showed that Women experienced high level of indirect trauma of social disaster than men.

  • The purpose of this study was to develop and validate Korean version of Deaf Acculturation Scales(DAS). Pilot items were made a faithful translation of the Acculturation Scales of Maxwell-McCaw and Zea (2011) and were modified for Korean Deaf people. The Scale involves two dimensions, in order to measure the acculturation of Deaf people; Deaf acculturation and hearing acculturation. Using factor analysis, we developed a Korean version of DAS consisted of twenty-five items for Deaf acculturation dimension and twenty-five items for hearing acculturation dimension. These analysis supported the four factors of Deaf acculturation dimension and the five factors of hearing acculturation dimension. Reliability, assessed by Cronbach's ${\alpha}$, was .93 for Deaf acculturation and .93 for hearing acculturation, respectively, which confirm the Koran version of DAS. Construct validity was demonstrated through correlation with Deaf acculturation-related variables: age, age of Deafness, Degree of hearing loss, American Sign Language ability, and lip-reading ability. Criterion validity was supported by correlation with Collective Self-Esteem Scale. Limitation and implication of this study and direction for future research were discussed.

  • The purpose of this study is to emphasize the importance of the safety and health ability to safely protect body in a risky situation in infancy, but due to the lack of a valid test tool for measuring infant safety knowledge, measure the safety and health knowledge of infants. In order to achieve the purpose of the study, opinions of education experts and early childhood education experts were collected, and suitable factors for measuring safety and health knowledge of children aged 3-5 years were extracted. The measurement questions developed based on this were surveyed on 186 children aged 3-5 years old to verify the relevance of the question composition and the reliability of the contents. In the distribution of the item response, values of 0.8 or less were deleted, and items with a correlation of r<.40 or less were also deleted, and the reliability test showed more than .70. After exploratory factor analysis, it was developed into 23 questions in 3 areas. The total score of safety and health knowledge for the final question and the degree of correlation were above .80. The tool for measuring child safety and health knowledge developed in this study was confirmed to be appropriate for item discrimination, item reliability, and content validity, and thus will be used as basic data for measuring child safety and health knowledge. After the early childhood safety and health education program is implemented, Further research should verify the effectiveness of the early childhood safety and health program.

  • Objective:This study was carried out to evaluate the reliability and validity of the Korean form of the Children's Yale-Brown Obsessive Compulsive Scale(CY-BOCS). Method:Forty-two children with obsessive-compulsive disorder(OCD)(31 boys and 11 girls, aged 7 to 18 years) were assessed with CY-BOCS. Interrater agreement was assessed by two raters in subsample(n=20). discriminant and convergent validity were assessed by comparing CY-BOCS scores to Clinical Global Impression-OCD(CGI-OCD), Leyton Obsessional Inventory-Child Version (LOI-CV), State-Trait Anxiety Inventory for Children(STAI-C), and Child Depression Inventory(CDI). Results:Internal consistency was high, measuring 0.86 for the 10 items and total score. The intraclass correlations for the CY-BOCS total, obsession, and compulsion scores were 0.94, 0.94, 0.84, suggesting excellent interrater agreement for subscale and total scores. The CY-BOCS total score showed highest correlation with CGI-OCD(r=0.88), and significant correlation with LOI-CV(r=0.51), Trait Anxiety score(r=0.43), and CDI scores(r=0.49), but it was not correlated with State-Anxiety score(r=0.25). Conclusion:The results of this study indicate that the Korean form of CY-BOCS is a reliable and valid scale for rating obsessive-compulsive symptom severity.

  • This study was conducted to develop items to measure scientific core competency based on statements of scientific core competencies presented in the 2015 revised national science curriculum and to identify the validity and reliability of the newly developed items. Based on the explanations of scientific reasoning, scientific inquiry ability, scientific problem-solving ability, scientific communication ability, participation/lifelong learning in science presented in the 2015 revised national science curriculum, 25 items were developed by five science education experts. To explore the validity and reliability of the developed items, data were collected from 11,348 students in elementary, middle, and high schools nationwide. The content validity, substantive validity, the internal structure validity, and generalization validity proposed by Messick (1995) were examined by various statistical tests. The results of the MNSQ analysis showed that there were no nonconformity in the 25 items. The confirmatory factor analysis using the structural equation modeling revealed that the five-factor model was a suitable model. The differential item functioning analyses by gender and school level revealed that the nonconformity DIF value was found in only two out of 175 cases. The results of the multivariate analysis of variance by gender and school level showed significant differences of test scores between schools and genders, and the interaction effect was also significant. The assessment items of science core competency based on the 2015 revised national science curriculum are valid from a psychometric point of view and can be used in the science education field.
