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: The purpose of this study was to investigate the validity and reliability of the measurement of shoulder joint motions using an inertial measurement unit (IMU). Methods: For this study, 33 participants (32 females and 1 male) were recruited. The subjects were passively positioned with the shoulder placed at specific angles using a goniometer (shoulder flexion $0^{\circ}-170^{\circ}$, abduction $0^{\circ}-170^{\circ}$, external rotation $0^{\circ}-90^{\circ}$, and internal rotation $0^{\circ}-60^{\circ}$ angles). Kinematic data on the shoulder joints were simultaneously obtained using IMU three-dimensional (3D) angular measurement (MyoMotion) and photographic measurement. Test-retest reliability and concurrent validity were examined. Results: The MyoMotion system provided good to very good relative reliability with small standard error of measurement (SEM) and minimal detectable change (MDC) values from all three planes. It also presented acceptable validity, except for some of shoulder flexion, shoulder external rotation, and shoulder abduction. There was a trend for the shoulder joint measurements to be underestimated using the IMU 3D angular measurement system compared to the goniometer and photo methods in all planes. Conclusion: The IMU 3D angular measurement provided a reliable measurement and presented acceptable validity. However, it showed relatively low accuracy in some shoulder positions. Therefore, using the MyoMotion measurement system to assess shoulder joint angles would be recommended only with careful consideration and supervision in all situations.

Purpose: The purpose of this study was to develop a scale of free nursing home adjustment for the elderly in Korea. Method: The developmental processes were construction of a conceptual framework, development of preliminary items, verification of content validity, twice data gathering, verification of construct validity, and reliability of final items. The first 53 preliminary items were obtained through review of literatures about nursing home adjustment and in depth interviews with 5 staffs of nursing home. These items were reviewed by five specialists for content validity and 39 items were chosen. The first data was collected from 107 elderly residing in 3 nursing homes and the second survey was from 147 residents who were living in five nursing homes. Finally this data was analyzed for construct validity and reliability. Result: There were 23 final items which were sorted into 5 factors. The factors were identified as 'Relocation distress symptom'(8items), 'Making friends'(4items), 'Acceptance of new residence'(6items), 'Difficulty in group life'(3items), and 'Having self-worth'(2items). The cumulative percent of variance was 53.466%. The reliability of the scale, Cronbach's alpha was .837. Conclusion: The result of this study could be used for measuring nursing home adjustment of the elderly. However, for further validity and reliability, repeated researches are needed.

Purpose : This methodological study develops an oral health assessment tool for critically ill patients. Method : From February 15 to April 30, 2014, this study was conducted to test the validity and reliability of the tool at two general hospitals and three medical and surgical intensive care units (ICUs) in Seoul, Korea. Results : The result of the intraclass correlation coefficient to test the between-observer reliability by analyzing the oral health assessment scores before and after oral nursing care showed that .93 of before oral care and .90 of after oral care. The correlation coefficient values of .68 (p<.001) and .71 (p<.001) before and after providing oral nursing care, respectively, indicated the presence of a statistically significant correlation between the tool and the criterion. Using the paired t-test, the differentiated validity of the tool was tested in patients who had developed pneumonia after entering the ICU. A statistically significant difference in scores was found between the time of entering the ICU and that of developing pneumonia (t=-8.73, p<.001), which provided evidence for the differentiated validity of the tool. Conclusions : Since the validity and reliability of the tool developed in this study were verified, this tool can be used to assess the oral health conditions of critically ill patients.

This study investigates the influence of Likert scale formats such as the number of response categories and the inclusion of a mid-point from a methodological point of view using instruments that measure a fashionmarketing-related subject. Using a self-administered questionnaire, 201 respondents rated their economic clothing shopping orientation on three formats of scales that differed only in the number of response categories (ranging from 5 to 7) from February 8 to February 12, 2010. Descriptive statistics, Spearman's rank order correlation, t-test, exploratory factor analysis, confirmatory factor analysis, Pearson's correlation, and Cronbach's alpha were used in the analysis. The results are as follows. First, three scale formats were generally suitable for use due to validity and reliability. Second, the response results varied with the number of categories and the inclusion of a mid-point, although the differences were statistically insignificant (with only a few cases that differed). Third, construct validity was more secure in scales with fewer categories, whereas convergent and discriminant validity was generally good in all scale formats. Fourth, reliability coefficients were higher in scales with more categories. Fifth, the number of categories was of greater importance to instrument design than the inclusion of a mid-point. Implications for appropriate scale designs are suggested in this study.

Background: The elderly in long-term care facilities tend to have a diminished oral health status, with a high prevalence of dental caries and periodontal disease, as reduced cognitive function, joint mobility, and gait ability hinder the performance of oral hygiene. To improve the oral health of the elderly at long-term care facilities, it is necessary to have precise guidelines for oral health care and assessment; however, such guidelines are not readily available. Therefore, the present study aimed to develop an oral care assessment tool with verified reliability and validity. Methods: The participants in this study were 100 elderly patients at a care facilities and 10 clinical dental hygienists. Collected data were analyzed using the descriptive statistics, content validity index, and inter-rater reliability, as well as the analyses of intra-class correlation coefficient. Results: After a review of relevant literature, a preliminary questionnaire comprised of seven questions related to the evaluation of oral health was formed. After revising and supplementing the questions through a content validity test, a total of nine questions were selected. Conclusion: The novel assessment tool developed for the present study is anticipated to allow analyses of the level of problems related to oral health care before routine and professional care. Moreover, regular oral health status check-ups will enable the early diagnosis and treatment of diseases.
