  • Purpose: The study was done to identify the construct validity and reliability of the life transition scale (LTS) for parents who have children with autism. Methods: Exploratory factor analysis (EFA) and confirmative factor analysis (CFA) were conducted to identify the most adequate measurement model for structural validity. Convergent validity and discriminant validity were also conducted for structural validity. Data were collected from 208 parents through self-reported questionnaires and analyzed with SPSS/WIN 15.0 and AMOS 20.0 version. Results: A four factor-structure was validated (${\chi}^2$=541.23, p<.001, GFI=.82, RMSEA=.07, IFI=.89, CFI=.89, PNFI=.73, Q (${\chi}^2/df$)=2.20) at the 3rd order of EFA and CFA, and factors were named as denying, wandering, despairing, and accepting. Both convergent and determinant validity for LTS were 100%. Cronbach's alphas for the reliability of each structure were .77-.90 and .83 for total structure. Conclusion: The four structures, 24-item instrument showed satisfactory reliability and validity. LTS has the potential to be appropriate for assessing the transition process of life for parents who have children with autism and provides basic directions for differentiated support and care at each stage.

  • 1. Objective TS-QSCD (The Two-Step Questionnaire for the Sasang Constitution Diagnosis) is one of the self-reporting Sasang-Constitutional diagnosis questionnaires and one constituted by a two-step discriminant function. The process of TS-QSCD is as follows. During the first step, the testers are classified into two groups: the Yangin(陽人) group and Eumin(陰人) group. Following this, the Yangin group is divided into the Soyangin group and Taeyangin group likewise the Eumin group is divided into the Taeumin group and Soeumin group. This questionnaire has the merits of an ordinary questionnaire with four discriminant functions and a decision tree method. The purpose of this study is to evaluate and standardize TS-QSCD 2. Materials and Methods TS-QSCD was administered to 352 random informants who were examined by professionals. Reliability was tested by inter-item consistency using cronbach's ${\alpha}$, and validity was tested by a two step discriminant function. Cross tabulation Analysis was also used to look into the distribution of responses among the groups. 3. Result 1) The reliability of TS-QSCD was relatively valid. The internal consistency of TS-QSCD (AB) was cronbach's ${\alpha}$= 0.815, and TS-QSCD (AC) was cronbach's ${\alpha}$= 0.832. 2) There was a significant difference in points between Eumin group teens and other age groups, between those of Soeumin teens and other age groups. 3) TS-QSCD corresponded with the real Sasang constitution at the rate of 65.0%. When using 61 questions and four discriminant function as with ordinary methods, TS-QSCD corresponded with the real Sasang constitution at the rate of 74.9%. 4. Conclusion 1) TS-QSCD that complements the merits of existing questionnaires is effective in diagnosing Sasang constitutions. 2) Deleting duplicate questions is thought to be one of the reasons for the decreased validity rate. 3) The lower the validity of the first step, the more we should build up at each second steps a way to rescue the groups which were assigned wrongly during the first steps. 4) This standardization of TS-QSCD would be helpful in making a program for diagnosing the Sasang Constitution

  • The purpose of this study is to develop clothing shopping orientation(CSO) scales fer more specific clothing shopping aspects. The specific aspects were the merchandise-related aspect and the store-related aspect. The two specific scales were developed based on the conceptual structure model of CSO and the general CSO scale. 16 items were selected for merchandise-related CSO, and 16 items were far store-related CSO. In addition, construct validity and convergent validity of those two specific scales were verified using AMOS 4.0, and discriminant validity were verified using Pearson's correlation. This study has significance in offering an advanced approach to the measurement of CSO.

  • To evaluate body image disturbance in Korea, the Body Image Scale(BIS) was developed and it's reliability and validity was tested. The BIS was administered to 33 subjects of normal controls and 64 patients consisting of mainly neurotic patients. The correlation coefficient, of test-retest reliability with an interval of 2 weeks was 0.88 and internal consistency coefficient Cronbach's alpha, was 0.80. Discriminant validity test indicated that there were significant differences in total BIS score between normal control group and psychiatric patients group after controlling the effects of age, sex, and educational level. Factor analysis showed two distinct dimensions, namely 'physical appearance' and 'physical health and strength'. The BIS appears to be a reliable, internally consistent and valid scale which can be used for assessing body image in Korea pupulations.

  • There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.

  • This study examined the reliability and validity evidence of the Korean version of Wechsler Primary & Preschool Scale for Intelligence(K-WPPSI-IV), which was standardized recently. Following the stratified sampling for Korean population in terms of region and maternal education level, 1,700 children aged 2.6~7.7 years were recruited for Korean norm development. The split-half reliability (N=1,700) was high(Fisher's z(.75-.89)) and test-retest reliability(N=100) was satisfactory ranging from .95 to .68. The inter-rater reliability(N=110) was very high(.96-1.0). Discriminant and convergent validities were revealed by correlational patterns among subtests and indices. Future studies are needed to extend both reliability and validity of K-WPPSI-IV by collecting data with a various sample group and a variety of instruments.

  • Purpose: This study was conducted to evaluate clinical competency of nursing students and to examine the validity and reliability of the scale. Methods: The Clinical Competency Scale was formed through modification of Lee's Clinical Competency Scale that was originally developed in 1990. The Clinical Competency Scale was applied to 203 nursing students. Construct validity, item convergent and discriminant validity, concurrent validity, and internal consistency reliability of the scale were evaluated. Results: Exploratory factor analysis supported the construct validity with a five factor solution; that explained 63.6% of the total variance. Concurrent validity was demonstrated with the Nursing Competence Scale (r=.78, p<.001). Cronbach's ${\alpha}$ coefficient for the scale was .96. Conclusion: The results of this study suggest that the Clinical Competency Scale has relatively acceptable reliability and validity and can be used in clinical research to assess clinical competency for nursing students.

  • Purpose: The purposes of this study were to develop a Minimal Insomnia Screening Scale for Korean adults (KMISS) and to evaluate psychometric properties and discriminant ability of the developed scale. Methods: Data from a cross-sectional survey of 959 Korean adults were analyzed to develop the summated insomnia scale, which was evaluated in terms of reliability, validity, and discriminant ability by receiver operating characteristics (ROC) curve analysis. Results: Item-total correlations ranged between .71-.79 and Cronbach's ${\alpha}$ was .87. Adequate validity was also evident. ROC-curve analysis showed area under ROC was .87 (95% CI: .84-.90) and identified the optimal cut-off score as ${\leq}20$ (sensitivity, .83; specificity, .75; positive/negative predictive values, .40/.95). Using this cut-off score, the prevalence of insomnia in the study sample was 26.3% and most frequent among women and the oldest group. Conclusion: Data supports the psychometric properties of KMISS as a possible insomnia screening instrument. KMISS also shows promise as a convenient ultra-short screening measure of insomnia for adults and epidemiological studies in community health care settings.

  • Background: The Functional Assessment of Cancer Therapy - Breast (FACT-B) scale is widely used to measure health-related quality of life in cancer patients. The aim of the present study is to validate the FACT-B in a sample of Iranian women with breast cancer. Materials and Methods: The sample consisted of 300 women selected through non-random convenient sampling procedure from oncology hospitals and clinics in Kermanshah and Shiraz cities. They were asked to fill in the Persian versions of the FACT-B scale, Hospital Anxiety and Depression Scale, the European Organization for Research and Treatment of Cancer quality of life EORTC QLQ30. Confirmatory factorial analysis of the methods, concurrent validity and discriminant, and Cronbach's alpha for internal consistency were applied. Results: Internal consistency using Cronbach's alpha was 0.63 to 0.93 for the subscales and 0.92 for the total scale. Significant correlations between FACT-B and other measures indicate that this scale had concurrent and discriminant validity. The values of fit indices were satisfactory. Conclusions: The Persian version of the FACT-B scale is valid and reliable and, therefore, the scale can be used in research and clinical settings to assess health-related quality of life in Iranian patients with breast cancer.
