The purposes of this study were to examine the reliability and validity of Korean translation of Pediatric Evaluation of Disability Inventory (PEDI-K) in school-aged children with cerebral palsy (CP). The PEDI-K, Functional Independence Measure for Children (WeeFIM) and Gross Motor Function Classification System (GMIFCS) were completed in 104 school-aged children with CP by therapists. The internal consistency of the PEDI-K was calculated by Cronbach's alpha (${\alpha}$) for assessing reliability. Concurrent validity was evaluated by correlation with the subsets of WeeFIM. Discriminant validity was assessed by comparing GMFCS levels with tests of the PEDI-K. The results showed that internal consistency was good (Cronbach's ${\alpha}$ ranged from .97~.98). Concurrent validity was demonstrated. The correlation with WeeFIM was high in the Functional Skills (self-care, r=.74~.94; mobility, r=.59~.91; social function, r=.65~.93) and in the Caregiver Assistance (self-care, r=.75~.94; mobility, r=.63~.90; social function, r=.78~.96). Discriminant validity was demonstrated on significant decreases in domain scores with increasing GMFCS levels. Reliability and validity have been demonstrated on the PEDI-K. This study extends usage of PEDI-K in clinical activities and research.

Purpose: Oral mucositis (OM) is a serious consequence of chemotherapy that cancer patients must undergo. The objectives of this study were to find out reliability and validity of patients self-reported daily questionnaires on OM, and the impact OM makes on daily functions. Method: To test the reliability of oral mucositis daily questionnaire (OMDQ), internal consistency of the instrument (Cronbach's ${\alpha}$ and correlation between items) and test-retest reliability were analyzed. Criterion validity and discriminative validity were evaluated using WHO, oral assessment guide, and Nicolatou assessment tool. Forty-eight acute leukemic patients under chemotherapy were enrolled in this study. Result: The Cronbach's ${\alpha}$ coefficient indicated sufficient internal consistency. Correlations of Mouth and throat soreness (MTS) and MTSActivity Limitations (MTS-AL) were statistically significant. MTS and MTS-AL scores on consecutive days were highly correlated (days13,14=.84-.96; test-retest reliability). OMDQ scale had high criterion validity and discriminative validity. Patients with more severe WHO OM grades had higher MTS mean scores. Conclusion: Oral mucositis in acute leukemic patients under going chemotherapy can be easily quantified by patient self-administered OMDQ with reliability and validity.

Purpose: The purpose of this study was to develop and evaluate a quality of life scale for Korean patients with cancer (C-QOL). Methods: The C-QOL was developed and validated as follows, item generation, pilot study, and psychometric tests. A total of 337 patients diagnosed with stomach, liver, lung, colon, breast, or cervix cancer were recruited. The patients were asked to complete the preliminary questionnaire comprising the content-validated items, the SF-36, and the ECOG performance status. The obtained data was analyzed using descriptive statistics, factor analysis, multidimensional scaling (MDS), multitrait/multi-item matrix, ANOVA, t-test, and Cronbach's alpha. Results: Preliminarily twenty-six items were generated through content validity and a pilot study. Factor analysis and MDS extracted a total of 21 items with a 5-point Likert-type scale (C-QOL). The C-QOL included five subscales: physical status (6 items), emotional status (6 items), social function (3 items), concern status (2 items), and coping function (4 items). The C-QOL established content validity, construct validity, item convergent and discriminant validity, known-groups validity, reliability, and sensitivity. Conclusion: The Newly developed C-QOL is an easily applicable instrument which established psychometric properties and reflected Korean culture. It is recommended for further study to examine the responsiveness of the C-QOL using a longitudinal research design.

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.
