Objective: The aim of the present study was to develop a valid and reliable scale that measures the healthy life styles among young adults. Design: A methodological study design was employed to develop and validate the Healthy Lifestyle Screening Tool (HLST). Methods: The validity and reliability of the HLST were established in accordance with DeVellis' 8 steps guideline for tool development. The question items were generated based on literature reviews and interviews, which were then classified into 12 categories. The HLST was administered to 272 students attending a Korean university. The reliability was tested using Cronbach's alpha. The validity of the scale was examined with the mean inter-item correlations (MIIC) and factor analysis, and was also examined for content validity by experts. Results: The reliability of the HLST was found to be acceptable, as indicated by a Cronbach's alpha of 0.71. In the validity test, items with less than 80% "agreement" ratings on the content validity index by experts were revised. The MIIC values were greater than 0.25. A factor analysis of 36 items extracted 9 factors (i.e., four items per factor), which together explained 50.4% of the variance. The HLST consists of 36 items that measure 9 factors based on a 4-point Likert rating scale, with 4 items per factor, as follows: sunlight, water, air, rest, exercise, nutrition, temperance, trust, and general physical condition. High scores on the HLST are indicative of a healthy lifestyle (HL). Conclusions: The HLST is a valid and reliable scale that can be used to measure HL among young adults. Identification of HL by using the HLST can provide guidance to integrated therapeutic approaches along with conventional physical therapy.

Objectives: This study was conducted to develop the Mobility to Participation Assessment Scale for Stroke (MPASS) and assess its content validity, internal consistency, inter-rater and intra-rater reliability, and convergent validity in people with stroke living in the community. Methods: The MPASS was developed using published data on mobility-related activity and participation timing in elderly individuals, and then reviewed by community physical therapists. Content validity was established by reaching a consensus of experienced physical therapists in a focus group. The MPASS was scored for 32 participants with stroke (mean age 61.75±4.92 years) by 3 individual testers. Reliability was examined using the intraclass correlation coefficient (ICC), internal consistency using the Cronbach alpha coefficient (α), and convergent validity using the Pearson correlation coefficient (r) to compare the MPASS to the Modified Rivermead Mobility Index as a referent test of mobility. Results: The MPASS consists of 8 items, and its scoring system provides information on the ability of people with stroke to reach a movement level enabling them to live in society, including interactions with other people and safe living in the community. The interrater and intra-rater reliability were excellent (ICC, 0.948; 95% confidence interval [CI], 0.893 to 0.982 and ICC, 0.967; 95% CI, 0.933 to 0.989, respectively). Internal consistency was good (α=0.877). The convergent validity was moderate (r=0.646; p<0.001). Conclusions: The newly developed MPASS showed acceptable construct validity and high reliability. The MPASS is suitable for use in people with stroke, especially those who have been discharged and live in the community with the ability to initiate sitting.

Background: The aim of the study was to test the validity and reliability of the Perceived Future Decent Work Securement Scale for Turkish nursing students. Methods: A cross-sectional, methodological study design was used. The study was carried out at three nursing undergraduate programs in Turkey during the academic year of 2020-2021 with 336 senior nursing students. Language validity and content validity analyses were performed for the scale adaptation, followed by confirmatory factor analysis (CFA) for construct validity. The reliability of the scale was determined using the test-retest and Cronbach's alpha internal consistency coefficient. Results: The scale-content validity index score was 0.988. In CFA, all goodness-of-fit indices verified the acceptable fit of the model; its root mean square error of approximation was 0.076; the normed fit index was 0.909; the standardized mean square residual was 0.097; the relative fit index was 0.881; the goodness-of-fit index was 0.915; the adjusted goodness-of-fit index was 0.872 and χ²/df = 2.932. The overall reliability was α = 0.86. The item-total correlations of the scale were above the acceptable level, and the test-retest analysis had a high correlation. The access to healthcare (14.68, SD 3.53) obtained the highest average score, and the adequate compensation (8.52, SD 3.76) was the lowest rated by the senior nursing students. Conclusion: The Perceived Future Decent Work Securement Scale is a valid and reliable scale to assess nursing students' future decent work securement.

Purpose: The aim of this study was to examine the validity and reliability of the Korean Version of the Spiritual Care Competence Scale (K-SCCS). Methods: A cross-sectional study design was used. The K-SCCS consisted of 26 questions to measure spiritual care competence of nurses. Participants, 228 nurses who had more than 3 years'experience as a nurse, completed the survey. Confirmatory factor analysis was used to examine the construct validity and correlations of K-SCCS and spiritual well-being (SWB) were used to examine the criterion validity of K-SCCS. Cronbach's alpha was used to test internal consistency. Results: The construct and the criterion-related validity of K-SCCS were supported as measures of spiritual care competence. Cronbach's alpha was .95. Factor loadings of the 26 questions ranged from .60 to .96. Construct validity of K-SCCS was verified by confirmatory factor analysis (RMSEA=.08, CFI=.90, NFI=.85). Criterion validity compared to the SWB showed significant correlation (r=.44, p<.001). Conclusion: The findings suggest that K-SCCS serves as an appropriate measure of spiritual care competence with validity and reliability. However, further study is needed to retest the verification of the factor analysis related to factor 2 (professionalisation and improving the quality of spiritual care) and factor 3 (personal support and patient counseling). Therefore, we recommend using the total score without distinguishing subscales.

Background: The purpose of this study was to evaluate reliability and validity of a 27-item Korean Version of the Impact of Weight on Quality of Life in adolescents ($IWQOL-Kids^{(C)}$: Korean Version). Methods: This instrument was administered to 872 adolescents (mean z-BMI: 2.61, mean $age{\pm}SD$: $13.9{\pm}1.2$, male: 51.9%). Reliability was tested by internal consistency method and item analysis, validity test was performed by index of content validity, exploratory factor analysis, confirmatory factor analysis and concurrent validity. Sensitivity was tested by ANOVA and t-test. Analyses were performed using SPSS and Amos 18.0. Results: By an exploratory factor analysis, 4 factors were extracted; 'Body esteem' consisted of 9 items with 35.9% of variance (social life: 6 items, 10.23%, physical comfort: 6 items, 8.21%, family relations: 6 items, 7.0%). Four factors explained 61.34% of total variance. Internal consistency coefficients ranged from .766 to .929 for scales on 27 items and equal to .920 for total score for both the 26-item and 27-item tools. A confirmatory factor analysis was conducted for the convergent validity and discriminant validity. The standardized factor loadings to test the convergent validity showed more than .5(C.R<1.965) on all paths after deletion of item PC1 (avoid stairs). The average variances extracted were more than .50 and the construct reliabilities were more than .70. The average variances extracted were stronger than the squares of correlation coefficient of inter-latent variables. Conclusions: These results support that the $IWQOL-Kids^{(C)}$: Korean Version with a 26-item is a reliable and valid tool in Korean obese adolescents.

Purpose: This study was conducted to develop a Korean version of the pediatric functional muscle test (K-PFMT) for children with motor developmental disorders, and to verify its reliability and validity. Methods: The subjects were 40 children, aged below 5 years. Each was scored on the K-PFMT by 14 physical therapists to determine inter-rater reliability and internal consistency. Additionally, 3 of the 14 therapists tested 20 children again one or two weeks later to determine test-retest reliability. The internal consistency was calculated by Cronbach's alpha. The inter-rater and test-retest reliability were calculated using the intraclass correlation coefficient (ICC). One-way ANOVA and the paired t-test were used to compare differences among the three evaluator groups and between the test and retest group. Concurrent validity was evaluated by Pearson's correlation with a total score of GMFM. Results: Chronbach's alpha was over 0.98 for each test item and 0.99 for the total items. There was no significant differences in the score of K-PFMT among the three evaluator groups except for a few items. The test-retest ICC was from 0.89 to 1.00 and from 0.82 to 1.00, respectively. There was no significant difference between the test and retest group, except for a few items. There were high significant correlations between K-PFMT and GMFM. Conclusion: This study showed that a K-PFMT with relatively high reliability and validity was successfully developed. The K-PFMT will be a useful tool for measurement of muscle strength of children with motor developmental disorder.

Purpose : The aim of this study was to assess the intra- and inter-rater reliability and validity of measurements of head, neck, and pelvis posture using a mobile application in subjects with forward head posture. Methods : Forty-eight volunteers (22 men, 26 women) participated in this study. Two raters independently examined whole body picture images in a lateral standing posture with arms crossed using a CA-Smart Posture Reminder (CA-SPR), and a rater took and calculated posture images twice to assess reliability. We measured five parameters: craniovertebral angle 1 (CVA1), anterior shoulder translation (AST), pelvic tilt (PT), knee angle (KA), and ankle angle (AA) in the subject's sagittal plane using CA-SPR. We examined whole spine X-ray images in the same position to assess validity. We measured four variables in the subjects: CVA2, translation distance (AHT), anterior pelvic plane (APP), and sacral slope (SS). The intra- and inter-rater reliability were calculated using the intraclass correlation coefficient (ICC). Convergent validity was calculated using Pearson's correlation coefficient. Results : The intra-rater reliability (ICC=.889 -.989) and inter-rater reliability (ICC=.800 -.980) were excellent for all variables measured using CA-SPR. The variables measured using CA-SPR and X-ray were significantly positively correlated (r=.623, p<.01). However, the correlation of the variables in the pelvis was not statistically significant. Conclusion : This study shows that a mobile application (CA-SPR) is a useful tool for measuring head and neck posture in subjects with forward head posture. However, further study is needed to measure pelvic variables when using a mobile application.

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.
