The purpose of this study is to develop clothing shopping orientation[CSO] scale reflecting the conceptual structure of CSO. For this purpose, a questionnaire composed of comprehensive 85 CSO items was developed through 2-step preliminary tests. Data was collected from two samples. One sample(n=559) was for scale development and the other sample(n=235) was for cross validity test. Descriptive analysis, correlation analysis, exploratory factor analysis, regression analysis, ANOVA, and confirmatory factor analysis were used for data analysis. For each lower-dimension within the CSO conceptual structure model, 1-2 items were selected based on the quantitative and the qualitative standards. As a result, a CSO scale composed of 31 items was developed, and reliability, construct validity, cross validity, convergent validity, discriminant validity, and criterion validity of the scale were verified. This study has significance in offering the standardized scale to both the academic and the practical fields.

This study was conducted in order to develop a parenting behavior scale for parents of school-age children and to analyze the scale in terms of both reliability and validity. Data were collected from a sample of mothers of $1^{st}$ to 3rd grade students in four elementary schools located in Seoul. 778 mothers were administered a parenting behavior scale with 123 items, and 779 mothers were asked to verify the validity of the developed scale in which 45 items remained after a series of analyses. Data were analyzed by means of exploratory factor analysis, confirmatory factor analysis, and correlation analysis. The results of factor analysis identified five factors, Warmth, Reasoning, Intrusiveness, Coercion, and Neglect. The Cronbach's ${\alpha}$ of each factor demonstrated results of .82~.86, suggesting that the scale had adequate internal consistency. Concurrent validity was established by using correlations between mothers' parenting behaviors and children's social competence. Moreover, cross-validation was also verified for the five factors. Considering the reliability and validity of this scale, it can clearly serve as a useful tool for assessing parenting behavior which is closely related to child development.

Purpose: The purpose of the study was to develop a knowledge scale of risk factors for fall among community-dwelling older adults. Further, the validity and reliability of the scale was developed. Methods: A preliminary scale was developed through content validity by five experts and targeted subjects using the CVI (Content Validity Index). Following the establishment of content validity, the scale was used with 359 community-dwelling older adults to further establish both validity and reliability of the scale. Specifically, construct validity using known-group comparison technique, and reliability using Cronbach's ${\alpha}$ were established. Results: After content validity testing, 44 preliminary items were selected. Construct validity was established by known group-comparison, in which scores between the fall and no fall groups were compared. The Cronbach's ${\alpha}$ of the final scale was .83. Conclusion: Reliability and validity of the scale were confirmed. This tool may be used for measuring knowledge of fall risk factor for the community-dwelling older adults.

Purpose: The purpose of this study was to develop a measurement scale of nursing competence for nurses working in general wards, and to test the validity and reliability of the scale. Method: A methodological study design was used, consisting of 3 steps as conceptual framework decision, measurement items development, and testing of validity and reliability. In order to verify content validity, 16 experts reviewed the concept of each competences and measurement items. The developed measurement items were tested from 301 nurses in one hospital. Factor analysis and item analysis were applied to establish the scale's construct validity and reliability. Result: The final scale consists of nine dimensions with 70 items. The overall scale reliability had a Cronbach's alpha of 0.98, and the demensions Cronbach's alpha ranged from 0.88 to 0.95. The factor loading of construct validity was from 0.40 to 0.83. The explained variance from the 9 extracted factors was 70.93% of the total variance, and final factors were labeled as critical thinking, resources management and professional development, ability of ward management, application of nursing process, ethical accountability, respectful consideration, patient centered approach, crisis management, and leadership. Conclusion: This measurement scale can be utilized to evaluate nursing competence for nurses working in general wards.

This article presents the development of a self-report measure of Korean Marital Satisfaction Scale. Based on 'Family Process Model'and interviews with 183 married couple, 3 domain structures with 74 items were identified, which included interactional process, emotional process, and intellectual process. It was administerd to 289 couples to test reliability and validity. Overall reliability coefficients were high for each of the individual domains($\alpha$=.62 to $\alpha$=.93). Face validity, content validity, content validity and concurrent validity respectively were demonstrated good. Additionally, divergent validity with scales of self-esteem and depression was observed. These results support the reliability and psychometric validity of the Korean Marital Satisfaction Scale in the assessment of key dimensions of marital process of Korean couples.

Background: This paper describes the development of a scale for measuring safety climate. Methods: This study was conducted in six manufacturing companies in Iran. The scale developed through conducting a literature review about the safety climate and constructing a question pool. The number of items was reduced to 71 after performing a screening process. Results: The result of content validity analysis showed that 59 items had excellent item content validity index (${\geq}0.78$) and content validity ratio (> 0.38). The exploratory factor analysis resulted in eight safety climate dimensions. The reliability value for the final 45-item scale was 0.96. The result of confirmatory factor analysis showed that the safety climate model is satisfactory. Conclusion: This study produced a valid and reliable scale for measuring safety climate in manufacturing companies.

Purpose: This study was done to develop a measure resilience in nurses. Method: Forty preliminary items were extracted from a view of the literature on concept analysis and scale development, and from in-depth interviews with nurses. These items were examined for content validity, reliability and validity. The scale was verified with 496 nurses working in three advanced general hospitals located in Seoul and Gyeonggido. Results: Factor analysis resulted in the creation of the final scale, which consisted of 30 items that were grouped into 5 factors: dispositional pattern, relational pattern, situational pattern, philosophical pattern and professional pattern. The explanatory variance was 56.25%. The reliability of the scale was Cronbach's ${\alpha}=.95$. Correlation of the scale with the Korean version of the Connor-Davidson Resilience Scale (K-CD-RISC), established its construct and concurrent validity (r=.74, p<.001). Conclusion: The resilience scale for nurses was found to have reliability and validity, and as developed in this study reflects nurses' disposition and was confirmed as a basis for developing and evaluating programs to increase nurses' resilience.

Purpose: The purpose of this study was to develop a scale to evaluate empowerment in woman with breast cancer and to examine the validity and reliability of the scale. Methods: The development process for the initial items included a literature review, interviews, and construction of a conceptual framework. The identified items were evaluated for content validity by experts, resulting in 3 factors and 48 preliminary items. Participants were 319 women with breast cancer recruited to test reliability and validity of the preliminary scale. Data were analyzed using item analysis, confirmatory factor analysis, criterion related validity, internal consistency and test-retest reliability. Results: The final scale consisted of 30 items and 3 factors. Factors, including 'intrapersonal factor' (14 items), 'interactional factor' (8 items), and 'behavioral factor' (8 items), were drawn up after confirmatory factor analysis. Goodness of fit of the final research model was very appropriate as shown by ${\chi}^2/df=1.86$, TLI=.90, CFI=.92, SRMR=.06, and RMSEA=.05. Criterion validity was evaluated by total correlation with the Cancer Empowerment Questionnaire .78. Cronbach's alpha for total items was .93 and test-retest reliability was .69. Conclusion: Findings from this study indicate that the scale can be used in the development of nursing interventions to promote the empowerment of women having breast cancer.

Purpose: This study aimed to develop and examine the validity and reliability of a self-efficacy scale for preventive health management related to premature labor (PHMSE-PL) for women of childbearing age. Methods: Instrument development and validation were undertaken in three steps: conceptualization through a literature review and in-depth interviews, item generation and evaluation of content validity, and evaluation of construct validity and reliability. The content validity, factorial structure validity, and internal consistency reliability of the PHMSE-PL were evaluated, and cognitive interviewing was undertaken. Data were analyzed using confirmatory factor analyses, Cronbach's α, and 95% confidence intervals (CIs). Results: The content validity was assessed by experts and was strengthened through cognitive interviews with women of childbearing age. The PHMSE-PL comprised 34 items across five factors. The construct validity of the PHMSE-PL was supported. Cronbach's α for the total scale was .97 (95% CI=.96-.97). Conclusion: An evaluation of the psychometric properties of the PHMSE-PL scale found it to be a valid and reliable tool for women of childbearing age. The scale appears to be useful for women of childbearing age to self-assess their preventive health management self-efficacy related to premature labor and for health professionals to evaluate and promote women's preventive health management.

This study developed the Place Attachment to Childhood Home Scale and evaluated its validity and reliability. Samples consisted of 418 college students of four universities. Data were collected by questionnaire based on retrospective questions about the childhood home. Factor analysis resulted in 5 dimensions of place attachment : affection, place identity, place rootedness, playfulness, and place dependence. Especially, playfulness was a unique finding. The result of confirmatory factor analysis supported the five-factor structure. There were also significant correlations among sub-factors. The reliability of the scale appeared high (Cronbach's ${\alpha}$ = .948). Criterion-related validity was confirmed by significant correlations of the present scale with Attachment Scale to Place (Hess, 1997) and the Inventory of Parent Attachment (Armsden & Greenberg, 1987).
