Purpose: To develop and test the validity and reliability of the Korean version of outcome expectations-2 for exercise. Methods: The Korean version of outcome expectations for exercise-2 was developed through forward-backward translation techniques. Content, criterion, and construct validity using confirmatory factor analysis and an internal consistency reliability were conducted. Survey data were collected from 200 older adults living in a community. Results: The Korean version of outcome expectations for exercise-2 had factor loadings of the 13 items ranged from .20 to .76, and was validated by confirmatory factor analysis (CFI=.829, NFI=.754, RMSEA=.086). Also there was a reliable internal consistency with a Cronbach's ${\alpha}$ for the positive domain of outcome expectations for exercise scale-2 of .73. Negative domain, however, reported slightly low Cronbach's ${\alpha}$ of .63. Conclusion: The findings of this study demonstrated that the Korean version of outcome expectations for exercise-2 had satisfactory validity to measure expectations regarding exercise among older adults in Korea. Negative domain, however, should be retested to verify reliability for the further study.

Purpose: The purpose of this study was to develop a meaning of life scale with high validity and reliability. Method: A conceptual framework composed of 4 phases of meanings of life was identified. And 49 preliminary items on a 4-points scale were developed through content validity. A reliability and validity test of the 49 items was conducted on 564 adults. By means of internal consistency of the 49 items, 1 item was deleted. To verify the 48 items, factor analysis, reliability test, and LISEREL were done. Result: Through exploratory factor analysis of the 48 items, 8 factors were extracted. These factors were labeled as 'self- awareness and self-acceptance', 'hope', 'responsibility awareness', 'love experience', 'self transcendence', 'relation experience', 'self contentedness', and 'Commitment'. Through LISEREL of the 48 items, 2 items were excluded and finally 46 itemsremained. Cronbach's Alpha of the 46 items was .94. The correlation coefficient of the Self-esteem scale was .79. Conclusion: By the above results, the researchers recommend the following: An exploratory study on the variables related to the meaning of life are needed for criterion validity of this scale. Studies on meaning of life of different groupa, and subjects are needed for reverification.

The purpose of this study were to translate the Fullerton Advanced Balance (FAB) scale into Korean and to verify the content validity by utilizing a back-translation method with a view to assessing balance function and the risk of falling in a clinical research setting. This research was conducted in six steps. First, three Korean physical therapists translated the FAB scale into Korean. Second, two bilingual professors of physical therapy and a physical therapist evaluated translation conformity of Korean-translated FAB scale. In the third and fourth steps, twelve physical therapists evaluated the degree of translation comprehension, and a translator back-translated the Korean FAB scale into the original language. Fifth, a bilingual professor of physical therapy and two native speakers evaluated the technical and conceptual equivalence between the original and translation versions. In this process, inappropriate translated items were revised using recommended substitute words or sentences, and all items were evaluated on the basis of three points or more on a rating scale in terms of translation comprehension, and the technical and conceptual equivalence of the back-translation. In the sixth and last step, the translation verification committee completed the final Korean version. The above process indicated that the content validity of the Korean-translated FAB scale was established by means of systematic translation methods, and it can therefore be used to assess balance function and the risk of falls in a clinical research setting.

Background and purpose : We previously developed questionnaire of Guibi-tang symtom on the Delphi method through the pathogenesis analysis. But developed a questionnaire was not verified in the clinical. So, to ensure objectivity, quantification and validity, verification is needed for questionnaire items before applying a clinical. On this study, we looked at whether questionnaire items had been validity in the clinical. Methods : Participants of this study were outpatients in eleven clinics. The resources were collected from 200 patients. SPSS 15.0 for Windows was used for statistical analysis : reliability analysis, factor analysis were used to verify the results Results and Conclusions : 16 items were selected through reliability analysis perforfed on about 22 items. After factor analysis, we have four component. Veryfy research of the Guibi-tang Patternization Questionnaire is needed in the future. Also I think that research should proceed about a lot of people.

Purpose: This study aimed to develop a scale measuring the Patient-Centered Nursing Culture (PCNC) and provide a basic tool to improve PCNC in Korea. Methods: A conceptual framework and construct factors were extracted through extensive literature review and in-depth interviews with nursing professionals. In total, 59 items were derived based on the pilot survey. Data were collected from 357 nurses working at general hospitals and analyzed for verifying the reliability and validity of the scale. Results: Nine factors containing 54 items were extracted from the exploratory factor analysis to verify the construct validity. The nine factors were top management leadership, policy and procedure, education and training, middle management leadership, supportive teamwork, nursing workplace environment, professional competence, patient-centered nursing activity, and nurses' values. These items were verified by convergent, discriminant, and concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's ${\alpha}=.96$). Conclusion: The developed PCNC scale is expected to be used as the tool for the development of theory and improvement of PCNC, the empirical testing for cause and effect of PCNC, the development of interventions, education and training programs for improving PCNC, and indicators for evaluation or accreditation of hospital service quality.

The purpose of this study was to verify the reliability and validity of the Job Meaning Scale for Nutrition Teachers (JMS-NT). The JMS-NT, the Nutrition Teacher Job Satisfaction Scale (NTJSS), and the Meaning in Life Questionnaire (MLQ) were administered to 180 nutrition teachers (female: 180, male: 0). The results showed that the JMS-NT had a three-factor structure in exploratory factor analysis. In addition, the test-retest reliability for all three factors of the JMS-NT was in the range of 0.69 to 0.85, and the internal consistency was in the range of 0.92 to 0.94, showing that they met the standards. The results of conducting Pearson correlation analyses between the JMS-NT and validity indicators such as the NTJSS and the MLQ were statistically significant, confirming the criterion validity of the scale. The above results show that the JMS-NT is a reliable and valid tool to measure the three factors of the job meaning of the nutrition teachers. Finally, the theoretical and practical significance, limitations, and future research tasks of the study were discussed.

Purpose: The purpose of this study was to develop an Allergic Rhinitis-Specific Quality of Life (ARSQOL) scale and verify its validity and reliability. Methods: ARSQOL was developed in 5 steps. Items for the preliminary instrument of ARSQOL were developed through a literature review and deep interviews with allergic rhinitis patients. Face validity with Content Validity Index (CVI), construct validity using factor analysis, and known group comparison, criterion validity test using correlation between ARSQOL and total nasal symptoms score (TNSS) were conducted to evaluate the validity of ARSQOL. Cronbach's ${\alpha}$ was used to evaluate the reliability of ARSQOL. Results: CVI for the items in the final ARSQOL were. 92. Five factors including discomfort associated with nasal symptoms (4 items), physical function (7 items), mental function (5 items), sleep disorder and social function (4 items), and problems of daily life (6 items) were identified through factor analysis and these five factors explained 66.6% of the total variance. The correlation coefficient between TNSS and the total score of life quality was -.69. In the group comparison, the persistent allergic rhinitis group showed lower ARSQOL scores than the intermittent patient group, and moderate to the severe allergic rhinitis patient group presented poorer ARSQOL than the mild symptom patient group. The Cronbach's ${\alpha}$ reliability coefficient was .95. Conclusion: Results show that the ARSQOL has good reliability and validity and thus ARSQOL is a useful scale for clinical practices and research as a measure of quality of life in adults with allergicr hinitis.

This study develops a valid and reliable scale to evaluate customer orientation for clothing salespeople in order to provide a foundation for systematic and empirical research in the apparel industry. The study was conducted in two phases. First, a scale was developed to evaluate the customer orientation of clothing salespeople through a qualitative method. The second phase involved the verification of the validity of the developed evaluation questions through a quantitative method. The subjects of this study were 327 clothing salespeople, and the results were analyzed using AMOS 7.0 and SPSS 15.0. The results were as follows: First, customer orientation questions were elicited from in-depth interviews with fashion sales-people, analyses of fashion magazine articles, and previous studies. From the results, 38 preliminary questions were selected based on categorization, modification, and expert analyses of the content validity. Second, in order to verify the validity of the customer orientation scale that consisted of 24 questions in 7 factors, we performed a verification of the convergent validity through an assessment of the magnitude of standardization factor loading, average variance extracted (AVE), and construct reliability. Discriminant validity was verified using the AVE of each of the two constructs and a comparison of the square of the correlation between the constructs. According to the results, the measured values were above or near the guideline values that demonstrates the validity of the customer orientation scale.
