  • The purpose of this study is to examine validity to Soeum scales by QSCC II. For this study, the objects are 336 patients who were made a diagnosis of Soeumin and 422 patients of other constitutions in Oriental Medicine & Western Medicine Cooperative Health Examination Center KyungHee University Medical Center. A systematic analysis has been made and the results are as follows. 1. We made a frequency analysis in 758 examinees' questions and concluded that 35 questions, among which 30 questions were existing and 5 were new, had statistical significance in making a diagnosis of Soeumin by more than 10% in comparison with answer frequency of other constitutions. 2. Because confidence coefficient of 0.8011 revised Soeum scales(35) rises up as compared with that of 0.6319 existing Soeum scales(51), I think revised Soeum scales reflect trait of Soeumin well and it is liable to shorten question time by controling questions. 3. Soeumin's discrimination probability in Soeumin was 55.4% by QSCCII, but that rises up to 64.3% by discriminant function made by revised Soeum scales. So there is statistical significance in discriminant function. 4. When questions in QSCCII are divided into body-spirit(體形氣像), looks-attitude(容貌詞氣), temper- talent(性質才幹), continuous mind(恒心), avarice(心慾), physiological symptoms(生理的 證) and pathological symptoms(病理的 證), response frequency and constitution discrimination probability falls in questions about avarice and pathological symptoms.

  • The purpose of this paper is to determine the extent to which job satisfaction affects organization commitment and organization performance among industrial security personnel. To this end, we attempted to conduct a four-week survey from August 28 to September 22, 2023, targeting about 150 workers working as industrial security guards in the field. According to the survey, the variables were comprised of "first, job satisfaction, second, organization commitment and third, organization performance" and based on this, three research hypotheses were proposed. After confirming that the internal consistency of each measurement item was satisfied, discriminant validity and conceptual reliability were calculated, and the discriminant validity of each variable was verified. As a result of the analysis, after conducting regression analysis to verify the research model, the results show that among the three research hypotheses, "Job Satisfaction ⇨ Organization Commitment, Job Satisfaction ⇨ Organization Performance" was found to be statistically significant and was adopted. We calculated that "Organization Commitment ⇨ Organization Performance" was not significant and was rejected.

  • The purpose of this study is to test the reliability and validity test of PWI to utility of PWI. this newly developed by Sejin Jang which measures stress. The subject were 186 workers in service area. Cronbach's a and Guttman split-half coefficient is used to test the reliability of PWI. Factor analysis and the correlation of the GHQ-60. GHQ-30, GHQ-28, GHQ-20, and GHQ-12 with the PWI is used to convergent validity and discriminant validity. The important results of this study are as follows : Cronbach's $\alpha$ coefficient of data was 0.894 and Guttman split-half coefficient was 0.7097. The PWI was classified as 13 principle component (eigenvalue>1.0). After exploring 4 factor structure according to previous study result, 4 factors was explained 40.5% out of the total variance. The factor 1 was explained 15.9% and then the rest three factor was 24.6%. Factor 2 and 4 showed good agreement but factor 1 and 3 did not. Depression-related items were classified two factors. Anxiety and depression-related items were loaded unifactor. It was not clear that the PWI was consist of 4 concepts(factors). The correlation of the GHQ-60, GHQ-30, GHQ-28, GHQ-20, and GHQ-12 with the PWI were 0.744~0.905. According to findings of this study. the PWI showed a high degree of validity and reliability. Thus it is recommended to use the PWI in general setting for screening for stress. In addition, it is necessary to clarify the concept of depression and anxiety. In the further study. it my be considered to the factor structure of PWI and studied to two or unidimensional factor structure.

  • Purpose: To test the reliability and validity of the Korean version of the Person-centered Climate Questionnaire-staff version (KPCQ-S) in long-term care institutions. Methods: A total of 297 staff in long-term care institutions including nine nursing homes (NHs) and 4 long-term care hospitals (LTCHs) were included. The KPCQ-S was developed following the WHO guidelines of the process of translation and adaptation of instruments. An internal consistency using Cronbach's ${\alpha}$ was tested for reliability. Exploratory factor analysis (EFA) was used to examine the construct validity. Convergent and discriminant validity were examined using Pearson correlation. Results: EFA demonstrated the construct validity of the 14-item KPCQ-S with three-factor solutions, specifically three factors (safety, everydayness, and community) in NHs and four factors (safety, everydayness, community, and comprehensibility) in LTCHs. Convergent validity was found in the correlation with the work satisfaction (r=.55). The KPCQ-S showed satisfactory internal consistency reliability (Cronbach's ${\alpha}=.91$). Conclusion: The KPCQ-S is found to be a reliable and valid tool for measuring staff perceptions of the person centeredness of long-term care environments.

  • Objectives : The aims of the current study were to assess the reliability and validity of the CoRe-Ditec-BS Questionnaire-II (BSQ-II; Blood stasis questionnaire-II) with 8 items including 5 items related women added to BSQ-I that was consisted of 36 items and developed in 2013. Methods : Between May 2014 and November 2014, 411 patients from 3 traditional Korean medical hospitals were asked to complete the BSQ-II. Each patient was independently diagnosed with BSS by two traditional Korean medical physicians from the same site. We estimated the internal consistency using Cronbach's ${\alpha}$ coefficient, the discriminant validity using the means score of BSS, and the predictive validity using logistic regression (sensitivity and specificity). Results : The BSQ-II had satisfactory internal consistency (Cronbach's ${\alpha}$ coefficient=0.765) and validity, with significant differences in the mean scores between the BSS($63.60{\pm}9.56$) and non-BSS groups($48.36{\pm}5.93$). The area under the receiver operating curve was about 98%, and the sensitivity and specificity were 91.4% and 94.9%, respectively. Conclusions : These results suggest that the CoRE-Ditec-BSQ-II is more reliable and valid instrument for estimating BSS than BSQ-I.

  • Objectives : The purpose of this study was to develop the Korean version of the Social Functioning Scale (KSFS) in the patients with schizophrenia. Methods : KSFS was administered to 90 schizophrenic patients and 80 their parents and 90 normal controls for examining the reliability and validity. Results : Data analysis showed statistically significant reliabilities and validities of KSFS. The test-retest reliability, rater vs. self-report reliability, and internal consistency for total scores of KSFS were 0.93, 0.44 and 0.94 respectively. Evidence for discriminant validity of KSFS comes from the results that the mean scores of schizophrenic patients were significantly higher than those of normal controls. Construct validity was assessed by calculating the 7 inter-areas correlations of the KSFS, and all areas were statistically significant. Significant correlations between the total scores of KSFS and those of SOFAS lend support for the concurrent validity of this instrument. Factor analyses were performed and two factors were extracted accounting for 63.7% of the variance. Sensitivity was assessed indirectly via the distribution and range of scores on the SFS. The normal control group showed a distribution around a higher mean with a moderate positive skew. Conclusion : KSFS was found to be a valid, reliable, and sensitive instrument which can be used to evaluate the degree of social functioning in the patients with schizophrenia.

  • This study examined the validity and the reliability of the perceived elderly stigma scale. Moreover, we investigated the relationships between the perceived elderly stigma and demographic factors (age, gender, education, and income). The initial scale consisted of 5 factors (ability, personality, appearance, authoritarian dependency, and child-obsession) and 28 items. In order to test the validity and the reliability of the scale, this study conducted a survey with 693 adults aged 18 to 65. Based on the confirmatory factor analysis (CFA), the scale was modified to 5 factors (ability, personality, appearance, authoritarian dependency, and child-obsession) and 15 items and its convergent validity and discriminant validity were confirmed. In terms of the relationships between the perceived elderly stigma and demographic factors, age had a negative relationship with the "ability" stigma, and education was a negatively associated with the "appearance" stigma.

  • Purpose: This study is to develop the Cultural Competence Scale for Registered Nurses (CCS-RN) and to examine its validity and reliability. Methods: The item pool was generated based on related scales, a wide review of the literature, and in-depth interviews with nurses according to Purnell's cultural competence model. Content validity was verified by nursing experts. Construct validity using exploratory factor analysis, convergent validity using correlation coefficients, discriminant validity, internal consistency reliability, and test-retest reliability were examined. Results: The CCS-RN consists of a 35-item/7-factor solution with 54.1% of the total variance explained. The convergent validity of CCS-RN was supported. Cronbach's ${\alpha}$ was .94 for the total scale and ranged from .77 to .90 for the seven factors. Test-retest reliability was moderate. Conclusion: The evaluation of the psychometric properties of the CCS-RN shows that this scale is expected to be a valid and reliable measure of cultural competence among nurses. This scale may be useful for assessing nurses' own cultural competence and thus contribute to strengthening cultural competence.

  • Purpose: The purpose of this study was to evaluate the methodological quality of nursing studies using structural equation modeling in Korea. Methods: Databases of KISS, DBPIA, and National Assembly Library up to March 2014 were searched using the MeSH terms 'nursing', 'structure', 'model'. A total of 152 studies were screened. After removal of duplicates and non-relevant titles, 61 papers were read in full. Results: Of the sixty-one articles retrieved, 14 studies were published between 1992 and 2000, 27, between 2001 and 2010, and 20, between 2011 and March 2014. The methodological quality of the review examined varied considerably. Conclusion: The findings of this study suggest that more rigorous research is necessary to address theoretical identification, two indicator rule, distribution of sample, treatment of missing values, mediator effect, discriminant validity, convergent validity, post hoc model modification, equivalent models issues, and alternative models issues should be undergone. Further research with robust consistent methodological study designs from model identification to model respecification is needed to improve the validity of the research.

  • Despite the recent sharp growth in the baby product market, previous studies on preschooler clothing have centered primarily on surveys regarding body size and consumer buying behavior, with little emphasis given to consumption value in preschooler clothing. This study aimed to assess the feasibility of using standards of consumption value to examine the behavior of those who buy preschooler clothing. The research subjects were mothers of preschoolers aged 1 to 6 years. They were asked to complete a questionnaire online at major parenting blogs found on portal sites (n=346). The questionnaire contained 41 questions based on a literature review, and 25 questions having convergent and discriminant validity were analyzed. By conducting a regression analysis of standards of consumption value in preschooler clothing and their perceived value, the feasibility of the standards was assessed. The results showed that consumption value in preschooler clothing was associated with 21 questions and 8 factors. The factors measuring consumption value included vicarious satisfaction, social value, functional value, convenience, financial value, aesthetic value, uniqueness, and circumstantial value. This study is significant in that it expands the scope of research on preschooler clothing, lays the groundwork for measuring consumption value in preschooler clothing, and predicts consumer behaviors by identifying the consumption value among mothers of preschoolers.
