Objective : The 18-item Obsessive-Compulsive Inventory-Revised (OCI-R) is widely employed to assess symptoms of obsessive-compulsive disorder (OCD). However, this instrument's factor structure does not align with contemporary dimensional models of OCD. Therefore, the objective of this study was to examine psychometric properties of the 12-item Korean OCI (OCI-12) on four obsessive-compulsive symptom dimensions, in patients with OCD. Methods : A total of 157 patients with OCD and 51 healthy controls completed psychological measures, including the OCI-R, Dimensional Obsessive-Compulsive Scale (DOCS), and scales evaluating anxiety and depressive symptoms. Pychometric characteristics of the OCI-12 with three neutralizing and three hoarding items eliminated from the OCI-R, were analyzed. Results : All OCI-12 items registered excellent internal consistency at 0.83. Confirmatory factor analysis revealed strong association between individual items and their proposed latent factors (i.e., subscales). Convergent validity was appropriate. A high correlation was particularly observed for the DOCS score (r=0.71, p<0 .001). Moreover, the OCI-12 was as sensitive as the OCI-R for determining effects of empirically supported treatment for OCD. Conclusion : The OCI-12 is a 12-item measure that adheres to the prevailing 4-factor model of OCD dimensions. Like OCI-R, it possesses good to excellent psychometric properties, including reliability, validity, and sensitivity to treatment.

The purpose of the study was to verify validity and reliability of performance assessment in home economics by applying performance assessment tools developed by Korean Curriculum Assessment Institute and by the researcher to a class of 17 high school female students in a rural area. For the purpose of this study, the research question was formulated and addressed:“How are the validity and reliability of performance assessment in home economics\ulcorner” The results of the study were as follows. 1. The results of testing validity a. Thirteen high school home economics teachers, whose average teaching years is ten years verified high validity in the contents of performance assessment. b. In the validity of the items that is verified being based on the scores of high school entrance examination of 2000 school year, the essay type showed its characteristics as performance assessment. c. The generalizability among assessment methods was not high. 2. The results of testing reliability Both Cronbach's $\alpha$, inter-item reliability of the assessment tools used in the research, and reliability among the raters were high. But reliability among the tasks was relatively low. This study proposed that the diverse performance methods, the increasing number of assessment, the explicit assessment criterion, and scoring criterion are needed to satisfying validity and reliability of performance assessment.

Purpose: This study was conducted to evaluate clinical competency of nursing students and to examine the validity and reliability of the scale. Methods: The Clinical Competency Scale was formed through modification of Lee's Clinical Competency Scale that was originally developed in 1990. The Clinical Competency Scale was applied to 203 nursing students. Construct validity, item convergent and discriminant validity, concurrent validity, and internal consistency reliability of the scale were evaluated. Results: Exploratory factor analysis supported the construct validity with a five factor solution; that explained 63.6% of the total variance. Concurrent validity was demonstrated with the Nursing Competence Scale (r=.78, p<.001). Cronbach's ${\alpha}$ coefficient for the scale was .96. Conclusion: The results of this study suggest that the Clinical Competency Scale has relatively acceptable reliability and validity and can be used in clinical research to assess clinical competency for nursing students.

The purpose of this study is to investigate the reliability and validity of the questionnaire of pattern identification (PI) in traditional chinese medicine (TCM), through the systematic review of china national knowledge infrastructure (CNKI) database. We searched the articles related with reliability and validity of the questionnaire of PI and published from January 1994 to December 2013. Seventeen questionnaires were analyzed in this study. The twelve (70.6%) questionnaires were developed on the base of specific disease, and five (29.4%) ones were developed on the base of non-specific disease. Three of PI questionnaires showed low inter-item consistency reliability. Exploratory factor analysis of construct validity, content validity, and criterion validity analysis were commonly used on the assessment of validity, but none of them was analysed at the same study. There was only one questionnaire of the ischemic stroke that examined the sensitivity and specificity of both training and test groups in spite of the absence of a gold standard.

Purpose : This study aimed to verify the validity and reliability of the Korean version of the nurses' attitude scale toward advance directives of patients. Methods : We translated and back-translated the original tool consisting of 20 questions and tested and verified its content validity. Questions for which its content validity has been verified, a preliminary investigation was conducted among 20 nurses working in ICU, followed by the actual investigation. Data were analyzed using SPSS version 24.0 for Windows and Mac and AMOS version 24.0. To verify the validity, an item analysis was conducted for all 398 samples, and then an exploratory factor analysis for 200 samples that were randomly selected, followed by a confirmatory factor analysis for the remaining 198 samples. Results : Korean version of advance directives attitude scale (K-ADAS) consisting of 14 questions - 7 questions on 'patient rights,' 4 questions on 'role of a nurse,' and 3 questions on 'ethical judgment' - was verified its validity and reliability. Conclusion : In this study, the validity and reliability of the K-ADAS have been verified. We expect the verified tool to be useful in various fields that measuring the nurses' attitude toward advance directives of patients.

The purpose of this study was the development of a scale to assess daily hassles coping behaviors for school aged children. The subjects were 398 children consisted of 197 3rd grade an 201 6th grade. They were selected from elementary school in Seoul, InCheon, DaeJeon, GwangJu and Pusan(202 males and 196 females) A questionnaire as the methodological instrument composed of 65-item daily hassles coping scale, demographic questions, 27-item Children's Depression Inventory and 20-item Locus of Control Scale. Statistics such as mean, %, X2, Cramer's V, Cronbach's α, factor analysis and Person's γ was used for used data analysis. The major findings of this study were as follows; 1)55 items of the 65-item scale were selected through item discriminant method. The discriminant coeffcients of the items(Cramer's V) ranged from .35 to .68. 2)5 factors were extracted from the 1st and the 2nd factor analysis. The subscales labelled 'active' 'passive' 'aggressive' 'avoidant' and 'social support seeking' coping. The criterion validity of this scale was assessed by computing the correlation measures of Children's Depression Inventory and Locus of Control Scale with this scale. Most coefficients were significant(ranging from r=-.16 to r=.40,p<.01,p<.001), although their correlations were modest. 3)Finally, the internal consistency of this scale appeared to be at an acceptable level(Cronbach's α=.90)

This study investigated whether the schema modes have validity in Korean adults. We examined the validity and reliability of the Schema Mode Inventory (SMI) in a Korean adult sample (N = 768; Mean age = 22.29 years; range = 19-55 years; 69.3% Males). Psychometric properties, such as factor structure, internal reliability, as well as intercorrelations among subscales were assessed. Confirmatory factor analyses yield satisfying fits for a 61-item Korean Schema Mode Inventory. Thirteen Schema Mode Inventory scales were found to have adequate reliability of the original 14 schema factors. Furthermore, the SMI scales differentiated between depressed and non-depressed participants as theoretically predicted. These findings imply that the SMI is a sound instrument to measure the schema mode model in a Korean setting for assessment prior to schema therapy.

The primary goal of the study was to provide some preliminary validity evidence for the Vocabulary Grade Levels Test (Busan Metropolitan City Office of Education, 2009), which is designed to measure the receptive vocabulary knowledge of learners in L2. For the purpose of the current study, 327 participants at the elementary school participated in the study and were asked to take two different vocabulary tests. Namely, a Vocabulary Size Test (Nation, 2001) and a Vocabulary Grade Levels Test. The data were analyzed using correlation in order to discover the relationship between these two types of tests. Following this, the Rasch analysis was conducted to examine the reliability and validity of the measurement in question. The data analysis showed that both grade separation reliability and item separation reliability were high, indicating that the Vocabulary Grade Levels Test well discriminates learners with a wide range of proficiency levels. The findings of the study are discussed, along with further improvements in order to ascertain the validity of this particular vocabulary test.
