Purpose: The purpose of this study was to develop and validate of a knowledge scale for lymphedema in patients with breast cancer. Methods: 34 preliminary items were made according to literature review, then verified content validity, construct validity, and reliability of the scale. 28 items among them were confirmed through content analysis by 4 experts. After a preliminary test, a survey for 156 breast cancer patients was performed for confirming construct validity and reliability. The data were analyzed using factor analysis, independent t-test, and KR-20. Results: This scale had 28 items consisting of 2 categories: prevention and self-care of lymphedema. Construct validity was confirmed by known-group technique because there were some categories consisted of just one or two items, and some mismatches between categories and items in factor analysis. Women who were educated about lymphedema scored significantly higher than women who had not (t=-3.92, p<.001). Reliability was appropriate (KR-20=.81). A percentage of correct answers was 74.6%, but it was from 31.8% to 96.1%. Conclusion: The study shows that this scale is reliable and valid to measure the knowledge of lymphedema. This scale can be effective to assess and educate the patients with breast cancer.

Purpose: To validate the Korean Version of the Jefferson Empathy Scale for Health professionals (K-JSE-HP) in a sample of Korean nurses. Methods: Internal consistency reliability, construct and criterion validity were calculated using SPSS (22.0) and AMOS (22.0). Data were collected from 253 nurses (230 women, 23 men) working at one university hospital in Seoul, South Korea. Results: The Korean version of JSE-HP showed reliable internal consistency with Cronbach's alpha for the total scale of .89, and .74~.84 for subscales. The model of three subscales for the K-JSE-HP was validated by confirmatory factor analysis (${\chi}^2=864.60$, Q=6.55, p<.001, CFI=.94, NNFI=.92). Criterion validity compared to the Interpersonal Reaction Index (IRI) showed significant correlation. Conclusion: The findings of this study demonstrate that the Korean JSE-HP shows satisfactory construct and criterion validity and reliability. It is a useful tool to measure Korean nurses' empathy.

Fashion stress is a pertinent aspect of modern consumer culture that has been underexplored in academic research. This study developed a conceptual framework of fashion stress and a multidimensional scale to measure consumers' fashion stress. The qualitative study included literature reviews on consumption stress, shopping stress, and consumer behavior, as well as focus group interviews to gain insight into various dimensions of fashion stress. NVivo 12.0 was used to analyze the qualitative data and identify core categories following the grounded theory methodology. The quantitative study involved a preliminary and a primary surveys to verify the validity and reliability of the fashion stress scale. A total of 220 questionnaires were used for data analysis. The results show that fashion stress consists of eight factors: care, shopping, fit, brand, financial, closet, style, and disposal. Choice difficulty plays a significant role in all factors of fashion stress. Moreover, shopping stress had a negative impact on impulse buying, while other factors such as fit, brand, closet, and disposal stress had a positive impact on impulse buying. Thus, fashion stress is a potential antecedent of impulsive consumer behavior. The results also confirm the validity and reliability of the scale. The fashion stress scale developed in this study offers researchers a valuable tool for assessing and understanding consumer experiences.

Purpose: Research related to social support in Korea has been hampered by paucity of measurement tools reflecting Korean culture. The aim of the study was to develop Korean social support questionnaire (KSSQ) based on the Korean social support pyramid and to test psychometric properties of the KSSQ. Methods: The questionnaire was administered to 701 subjects and 658 college students. Psychometric analyses included factor analyses, expert validity, criterion-related validity, internal consistency, and test-retest reliability. Results: A principal components analysis support for construct validity, eliciting a three factor solution accounting for 65.46% of variance in scores. Concurrent and discriminant validity supported criterion-related validity. Internal consistency of reliability was support with Cronbach's alpha of .97-.98 for the entire scale. Test-retest reliability was .76. Conclusion: This initial testing of KSSQ to measure Korean social support demonstrates evidence of reliability and validity. Assessment of known-group validity and norm establishment of KSSQ are suggested to provide further sound psychometric properties and practical measurement tools.

Purpose: To develop Pregnancy Risk symptom Perception Scale (PRPS) and evaluate its validity and reliability. Methods: A preliminary 30-item version of PRPS was developed through literature review, in-depth interview, and Content Validity. Each item was scored on a four-point Likert scale. The preliminary scale was developed based on 301 pregnant women who visited a hospital. Date were analyzed using item analysis, factor analysis, confirmatory factor analysis, Pearson's correlation coefficients, and Cronbach's ${\alpha}$ (0.90 for total item, 0.80 to 0.88 for factors). Results: The PRPS consisted of 27 items. Three factors (physical, environmental, and emotional factors) explained 55% of the total variance. Cronbach's Criterion validity was supported by comparison with the Perception of Pregnancy Risk Questionnaire (r=0.34). In reliability test, the reliability coefficient of pregnancy risk symptom perception was high at 0.90. Conclusion: These results suggest that the pregnancy risk symptom perception scale developed in this study comprises items that can assess the level of pregnant women's pregnancy risk symptom perception in Korea. Its validity and reliability were proven. PRPS can be utilized to measure pregnant women's risk symptom perception during pregnancy. PRPS will contribute to the development of systematic prenatal care and effective risk management.

In this study, the Infants & Toddlers' Playfulness Scale(ITPS) was developed and its reliability and validity were examined. The participants in this study consisted of 656 parents whose children were 8 to 36 months old. Five factors were identified from the results of the exploratory factor analysis performed on the 29 items that had been derived by analyzing existing research. The Goodness of Fit Indices(GFIs) of the confirmatory factor analyses, performed on the 1st-order 5-factor model and the 2nd-order one factor model, were both satisfactory. Concurrent validity was established by the high correlations of r = .631~.808(p < .01) between each factor of the ITPS and the total score of the Children's Playfulness Scale(CPS), an existing measure for children's playfulness. The reliability of each factor, as measured by Cronbach's ${\alpha}$, ranged from .773 to .883. Consequently, the ITPS developed in this study can be seen as a reliable and valid scale that can be used by parents to measure the playfulness of their infants and toddlers in a multi-dimensional manner.

Purpose: The purpose was to develop a preliminary scale to measure Korean adolescents' health behaviors through a qualitative approach, to evaluate the scale psychometrically, and to develop a final scale. Methods: Participants were 61 adolescents for qualitative interviews and 1,687 adolescents for the psychometric evaluation. Procedure included content analysis of interviews to identify health behavior categories for Korean adolescents, pre-test to confirm that preliminary scale items were understandable, content validity by an expert panel, development of the web-based computer-assisted survey (CAS), and psychometric analysis to determine reliability and validity of the final scale. Results: A final scale was developed for both paper-and-pencil and CAS. It consisted of 14 health behaviors (72 items), including stress and mental health (10), sleep habits (5), dietary habits (12), weight control (4), physical activity (4), hygiene habits (5), tobacco use (5), substance use (2), alcohol consumption (4), safety (4), sexual behavior (9), computer use (3), health screening (4), and posture (1). Conclusion: The scale's strong points are: 1) Two thirds of the final scale items are Likert scale items, enabling calculation of a health behavior score. 2) The scale is appropriate to Korean culture. 3) The scale focuses on concrete health behaviors, not abstract concepts.

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: Patients hope to receive 'respected nursing' which guarantees the right of privacy and treatment as a human being in hospitals. However, no specific tool has been developed to measure patients' perceived respect from nurses while staying in hospitals. This study was conducted to develop a tool to measure the respect that they experience in hospital. Method: A basic questionnaire was made based on research literature, pilot studies, and collected data via patients' interviews. The questionnaire was verified by 5 members of an expert group, a chief nurse in the clinical area and 10 patients. We distributed the questionnaires to 266 randomly selected inpatients and carried out analyses of factors and content to evaluate the validity and reliability of the questionnaire. Result: According to the results of factor analyses, three factors such as 'cordial treatment', 'consideration', and 'recognition' were extracted, which took up to 61 percent from all variants. Final questionnaires has 30 questions on a 4-point scale. Conclusion: The questionnaire which was designed through the study showed a high reliability and validity. We anticipate that this questionnaire will contribute to fostering nursing care with respect for patients.
