  • Purpose: The purpose was to determine the content validity of a semantic revision of items on a reliable and valid instrument, the Sieloff-King Assessment of Group Outcome Attainment (Power) within Organizations in Korea (K-SKAGOAO). Methods: The target population for research was chief nurse officers (CNOs) of all hospital within Korea. A sample of 303 hospitals from across the Korea was selected through a stratified random sampling process. A total of 174 CNOs comprised the final sample. Psychometric evaluation of the K-SKAGOAO included: (a) criterion-related validity (b) factor analysis and (c) internal consistency reliability using Cronbach's alpha coefficients. Results: The Convergent validity and criterion-related validity were supported. Cronbach's alpha coefficient for the K-SKAGOAO was .95. Subscale alphas ranged from .60 to .86. Conclusion: The K-SKAGOAO and related subscales show validity and internal reliability. A nursing group of any size can use the K-SKAGOAO to both assess the group's level of outcome attainment and develop strategies to further improve that level.

  • Purpose: This methodological study was done to develop a Nursing Competency Measurement Scale based on the clinical ladders of nurses working in wards. Methods: Thirty clinical experts and 501 ward nurses evaluated the content validity of the scale. A survey using the Nursing Competency Measurement Scale was conducted with 114 nurses to evaluate reliability and applicability of the instrument. Data were analyzed using SPSS/WIN 21.0. Results: A review of the literature identified 13 components of nursing competencies and 30 core nursing competencies based on each of the 4 grade clinical ladders. Cronbach's ${\alpha}$ coefficient for the total was .92. Cronbach's ${\alpha}$ reliabilities of each clinical ladder grade were .83 for Grade I, .84 for Grade II, .81 for Grade III, and .84 for Grade IV. The Content Validity Index (CVI) of the scale with 120 individual items was 0.976~1.000 for Grade I scale, 0.986~1.000 for Grade II scale, 0.984~1.000 for Grade III scale, and 0.992~1.000 for Grade IV scale. The expert group nurses' average degree of nursing competence measured using the scale was 3.38~3.75 out of 4.0. Conclusion: Through this process, 120 final questions were confirmed to represent items of the Nursing Competency Measurement Scale based on clinical grade.

  • Background: The assessment tool developed in other countries should be translated into Korean language using rigorous methodological approaches in order to be used in Korea. Because these procedures are insufficient for establishing the cross-cultural and linguistic equivalence, the need for statistical methods is raised. The Fullerton Advanced Balance Scale was translated into Korean and the content validity was verified through the back translation method, but the reliability and validity have not yet been proven by statistical methods. Objects: The purpose of this study was to investigate the reliability and validity of the Korean version of the Fullerton Advanced Balance Scale (KFAB) by statistical methods in elderly people. Methods: A total of 97 elderly adults (39 males and 58 females) participated in this study. Internal consistency of the KFAB was measured using Cronbach's alpha and an intraclass correlation coefficient (ICC) was used to assess test-retest reliability between the two measurement sessions. Concurrent validity was measured by comparing the KFAB responses with the Korean version of the Berg Balance Scale (KBBS) using the Spearman correlation coefficient. Construct validity of the KFAB was measured using the exploratory factor analysis to evaluate the unidimensionality of the questionnaire. The significance level was set at ${\alpha}=.05$. Results: The internal consistency of the KFAB was found be adequate with Cronbach's alpha (.96), and test-retest reliability was excellent as evidenced by the high ICC (r=.996). Concurrent validity showed high correlation between the KFAB and KBBS (r=.89, p<.001). Construct validity was evaluated using exploratory factor analysis. The result from Bartlett test of sphericity was statistically significant (p<.001), and the value of Kaiser-Meyer-Olkin measure of sampling adequacy was .93. Exploratory factor analysis revealed the existence of only one dominant factor that explained 76.43% of the variance. Conclusion: The KFAB is a reliable, valid and appropriate tool for measuring the balance functions in elderly people.

  • Objectives The purpose of this study is to provide more whiplash injury-specific measurement tools for Korean patients by measuring the validity and reliability of Korean version of Whiplash Disability Questionnaire (WDQ). Methods Bilingual clinicians translated the original WDQ into Korean. After consensus conference between researchers, it was back-translated into English. The pre-final version was completed and administered to 71 hospitalized patients diagnosed with whiplash injury. Validity was evaluated by concurrent validity. Reliability was assessed using Cronbach's ${\alpha}$ and intraclass correlation coefficient. Results The Korean WDQ showed good reliability with high internal consistency and intra-class correlation coefficient (Cronbach's ${\alpha}=0.96$, intraclass correlation coefficient [ICC]=0.82). Concurrent validity demonstrated positive correlations between Neck Disability Index, 36-Item Short Form Health Survey and WDQ. Conclusions The Korean version of WDQ is a valid and reliable tool for use as a measurement of whiplash injury in Korean patients, and it will be a very useful evaluation tool for both clinicians and researchers.

  • Objective : GRIT is a non-cognitive trait which is defined as perseverance and passion for long-term goals. It predicts success, performance and thedifference from other traits. The purpose of this study was to examine the reliability and validity of the Korean version of the GRIT scale. Methods : A total of 92 patients were enrolled in the study. All patients received psychiatric assessment including Clinical Useful Depression Outcome Scale (CUDOS), Clinical Useful Anxiety Outcome Scale (CUXOS), Patient Health Questionnaire (PHQ-15), Connor-Davidson Resilience Scale (CDRS), Brief Resilience Scale (BRS), and GRIT as well as demographic assessment. Cronbach's alpha coefficient of total GRIT score and the split-half reliability of each item was calculated to assess test reliability. Exploratory and confirmatory factor analyses were performed to select the best fitting model and assess construct validity. Finally, a correlation analysis was performed to check convergent and discriminant validity. Results : Cronbach's alpha coefficient for GRIT was found to be 0.85 and all Cronbach's alpha were more than 0.8 even in cases where all items were deleted. We found 3 appropriate factor models in exploratory factor analysis, compared them with 3 models and chose the 2-factor model as the most suitable based on the best fit test. Finally, correlation of the GRIT with CUDOS, CUXOS, PHQ-15, CDRS and BRS were statistically significant (all p<0.01), with relatively low correlation coefficient. Conclusion : This study indicates that the Korean version of GRIT is a reliable and valid instrument for investigating individual power of passion and perseverance.

  • The purpose of this study was to test the reliability and validity of the Infant Montessori Performance Assessment Scales developed by the authors. Subjects of the study consisted of 132 Montessori teachers and 50 infants who were attending Montessori home school throughout the whole country, using census method. Infant's age ranged from 6 to 24 months. Data were analysed by using SAS 8.2 PC program. Statistical methods employed were frequency, Cronbach's alpha, Kappa coefficient, test-retest correlation, construct validity, and concurrent validity. The Cronbach's alpha of 6 sub-scales included physical, creativity, practical life, sense, language, and cognitive education, which ranged from .70 to .86. And the! correlation of the test/re-test was .72. The correlation between the 6 sub-scales of Infant-Montessori Performance Assessment Scales and the total scores of 6 items ranged from .06 to .84. Therefore, the construct validity of Infant Montessori Performance Assessment Scales was verified. The Kappa coefficient of inter-rater reliability was .76. The correlation between the Infant Montessori Performance Assessment Scales and the Standardized Korean Creativity Traits Checklist(K-CTC) and the Korean Child Social Maturity Scales showed non-significant levels of .16 and .12 respectively. Conclusively, Infant Montessori Performance Assessment Scales developed by the authors were verified through the above reliability and validity tests. Specifically the Infant Montessori Performance Assessment Scales showed the relationship of the convergent and divergent validity with the Korean Child Social Maturity Scales and the Standardized Korean Creativity Traits Checklist, respectively.

  • Purpose: The purpose of this study was to validate the Korean version of shortened Nursing Decision-Making Instrument developed by Lauri & $Salanter{\ddot{a}}$(2002). Methods: The subjects were 247 nurses working in eight hospitals of Korea. Data were collected by questionnaires from June to July, 2012 and were analyzed by Principal Component Analysis for construct validity and Cronbach's ${\alpha}$ coefficient for reliability. Results: Factor loadings of the four subscales ranged from .32 to .73. The explained variance from the four factors was 48.54% of the total variance. The factors were named 'implementation of plan, monitoring and evaluation', 'plans of action', 'data collection', and 'data processing and identification'. The first factor consisted of 6 items which explained 13.21% of the total variance and the second factor contained 8 items. The Cronbach's ${\alpha}$ coefficients of the four subscales were from .64 to .81. Conclusion: The Korean version of the shortened Nursing Decision-Making Instrument has satisfactory construct validity and reliability. However, that the scores of the analytic items weren't reversed unlike the analysis method of the original tools is the biggest limitation of this study. In addition, based on the fact that there were several discrepancies for item interpretation of Korean comparing to the findings of the instrument development study, repetitive researches would be suggested.

  • The purpose of this study was to contribute to the relatively neglected area of out -patient satisfaction with physical therapy service by measuring and determining the factors affecting patient satisfaction in the Andong region. One hundred and forty-five subjects (81 males and 64 females) at 11 facilities with a mean age of 39.2 years (SD=16.2) responded to the satisfaction questionnaire. Each questionnaire contained a set of demographic questions and 19 patient satisfaction items. Cronbach's alpha test of reliability was used as the measure of internal consistency . The satisfaction scale had a good reliability coefficient : Cronbach's alpha=.8688. The average satisfaction score (minimum score=19, maximum score=95) was 75.4 ranging from 38 to 90. Respondent variables including sex, education, marital status, religion, medical security, average monthly income, and number of physical therapy out-patient department treatment visits were analyzed by t-test, ANOVA, and ANCOVA. Satisfaction with the service was largely unrelated to mallets of sex, education, occupation, or other demographic variables. However, marital status, age, average monthly income, and number of treatment visits in the out-patient department were significantly related to patient satisfaction. The analysis presented here could be replicatied with a larger sample in other areas. Other factors such as physical therapist availability, physical therapist competence, accessibility, waiting time, and atmosphere of the treatment area should be considered in further studies.

  • Purpose: The purpose of this study was to determine reliability and validity of the Postural Assessment Scale for Stroke Patients (PASS) in chronic stroke patients. Methods: A total of 43 stroke patients, who had a stroke more than 6 months previously, participated in the study. Reliability was determined by the intra-class correlation coefficient (ICC$_{3,1}$), Bland and Altman method and Cronbach's alpha by internal consistency. Validity was examined by correlation the PASS scores to the Berg Balance Scale (BBS), Trunk Control Test (TCT), and Fugl-Meyer Balance (FM-B) score. Results: The intra-rater reliability and the Absolute reliability of the PASS was good ICC$_{3,1}$=0.97 (95%CI 0.95$\sim$0.99) and excellent SEM=1.01 respectively. Cronbach's alpha value for PASS was found to be 0.94. There were significant correlations between the PASS and BBS, TCT, FM-B (r=0.65-0.96, p<0.01). Conclusion: The PASS provide reliable and valid instrument of the postural control assessment for chronic stroke patients.
