Purpose
The purpose of this study was to develop and verify a Quality of Life Scale (QOLS) specifically for hypertensive patients. Methods: In the development phase of the QOLS, initial items were derived based on literature review and content analysis through in-depth interviews. After verifying the content validity of the expert group, preliminary questions composed of 94 items were created and confirmed by conducting preliminary research on hypertensive patients. During the verification phase, the preliminary QOLS was administered to 392 hypertensive patients from general hospitals, medical clinics, and public health centers in Busan. Data were analyzed using item analysis, exploratory factor analysis, convergent validity, discriminant validity, criterion validity, and Cronbach’s ⍺. Results: The final scale consisted of 30 items derived from 5 factors. Five factors (negative emotion, acceptance of disease, self-reinforcement, social support, self-regulation) were extracted from the factor analysis, which explained 68.0% of the total variance. The convergent validity showed a positive correlation (r=.51, p<.001), discriminant validity showed an inverse correlation (r=-.60, p<.001), and criterion validity showed a positive correlation (r=.35~.64, p<.001). The Cronbach’s ⍺ was .94 and reliability of the subscales was .78~.92. Conclusion: The specific Quality of Life Scale for hypertensive patients (QOLS_HP) was composed of 30 items using a 5-point Likert scale. The scale demonstrated acceptable validity and reliability.

Purpose
The purpose of this study was to develop the Osteoporosis Self-Care Scale (OSCS-13) and verify its validity and reliability. Methods The subjects were 445 patients with osteoporosis who visited the hospital. They were randomly assigned into two groups as follows: 220 patients for exploratory factor analysis and 225 patients for confirmatory factor analysis. The OSCS-13’s construct validity, convergent-discriminant validity, structure validity, group validity, consistency reliability and test-retest reliability were evaluated. Results This study examined four factors and 13 items scored on a 5-point likert scale. The confirmatory factor analysis showed adequate model fit indices (Minimum/Degree of Freedom [CMIN/DF]=1.70, Root Mean Residual [RMR] =.03, Root Mean Square Error of Approximation [RMSEA]=.06, Comparative Fit Index [CFI]=.97, Tucker-Lewis Index [TNI]=.96, Incremental Fit Index [IFI]=.97). Convergent-discriminative validity and convergent validity were demonstrated using measures of defining issue. Internal consistency reliability and test-retest reliability were found to be acceptable, as indicated by a Cronbach’s α of .65~.92 and an intraclass correlation coefficient of .65~.80. Conclusion The OSCS-13 is a valid and reliable instrument. Hence, it is expected that this tool can be used to measure the level of self-care for patients with osteoporosis.

Purpose
This study aims to evaluate the Korean revised version of the Self-Care Behaviors Scale’s (SCBS-K19) validity and reliability.
Methods
The data of 203 rheumatoid arthritis patients at a university hospital in D metropolitan city in South Korea were collected from July to August 2020, using a convivence sampling method. The SCBS-K19 was analyzed utilizing SPSS 26.0 and AMOS 23.0 programs. The SCBS-K19’s content validity, structure validity, item-convergent/discriminant validity, convergent validity, and internal consistency and reliability were evaluated.
Results
Among the items in original version, the items with a ceiling or floor effect of 30% or more were deleted, thus, resulting in a revised version with five sub-areas and 19 questions. The confirmatory factor analysis’ results showed adequate model fit indices (c2/df=2.29, GFI=.85, RMR=.06, RMSEA=.08, CFI=.91, TLI=.89, IFI=.91). The items’ convergence and discrimination validity were verified using the extracted mean variance (.52~.66) and composition reliability (.80~.90). The convergent validity was satisfactory as shown by its correlation with the Self-as Carer Inventory (SCI) (r=.60, p<.001). The Cronbach’s ⍺ for the overall scale was .88, and that of five subscales ranged from .77 to .90.
Conclusion
The SCBS-K19 is a valid and reliable instrument. Therefore it is expected that this tool can be used to measure the level of self-care in Korean patients with rheumatoid arthritis.

Few instruments are available to measure nurses' perceptions of cultural competence in South Korea. Furthermore, the equivalence of factors between original and translated instruments has not been evaluated. The specific aims of this study were to identify the validity and reliability of a Korean version of the Cultural Awareness Scale (K-CAS) and to evaluate the equivalence of factors between the original CAS and the K-CAS. A total of 515 nursing students completed the 26-item K-CAS, 28-item Caffrey Cultural Competence in Healthcare Scale (CCCHS), and eight-item Openness to Diversity and Challenge Scale (ODCS). The K-CAS exhibited good reliability (alpha=.83) and construct validity by correlating with the CCCHS (r=.344, p<.001) and ODCS (r=.394, p<.001). Confirmatory factor analysis results of the K-CAS confirmed the same factor structure as the original CAS. The K-CAS could be a useful tool to assess the concept of cultural competence among nursing students and nurses.
