This study aimed to develop and validate a scale which could be used to evaluate mathematical interactions of parents with their young children. The subjects comprised 408 mothers of 4-6-year-old children. Means, standard deviation, $x^2$, Cramer's V, exploratory factor analysis, confirmatory factor analysis, Pearson correlations, and Cronbach's ${\alpha}$ were calculated. First, 49 items were developed through a review of relevant research, parent interviews, confirmation of item adequacy and content validity. These items were then edited down to a final list of 24 items representing 4 factors identified by exploratory factor analysis. Second, this 24-item. 4-factor scale was shown to have adequate construct validity, norm validity, and reliability by confirmatory factor analysis, Pearson correlation analysis, Cronbach's ${\alpha}$. In conclusion, the final mathematical interaction scale for young children's parents was composed of 24 items with 4 factors: "interaction regarding numbers and operations, measurements, and patterns", "interaction regarding data collection and result presentation", "interaction with picture books", and "interaction regarding shapes and figures"

This study developed a test entitled Clinical Critical Thinking Skills (CCTS) by using item response theory (IRT) and examined its validity. In the development stage, data obtained from a convenience sample of 627 undergraduate nursing students were analyzed using a discrimination and difficulty index with the TestAn 1.0 program. In the evaluation stage, data from a convenience sample of 284 nursing and non-nursing students were analyzed using a discrimination and difficulty index with the BILOG-MG program. Criterion validity was verified by the group comparison method. Five items received low discrimination index scores according to the IRT results. In terms of the criterion validity, CCTS scores differed according to major (t=2.21, p=0.028), location of high school (F=4.35, p=0.014), clinical experience (t=5.66, p=0.004), and grade point average (F=7.17, p< 0.001). The CCTS can be used to measure critical thinking skills in the clinical setting.

Purpose: To develop Korean Menstrual Symptom Scale (KMSS) for university students and test its reliability and validity. Methods: The scale was developed by intensive literature review, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity, and extraction of final items. Thirty-nine items were constructed. Data for validity and reliability testing were collected with a questionnaire survey from 391 university students. Data were analyzed with descriptive statistics, factor analysis, and reliability coefficients (Cronbach's ${\alpha}$) with the SPSS program. Results: There were 37 final items which were sorted into six factors: 'negative affection (8 items)', 'change of activity level (7 items)', 'physical symptom (9 items)', 'mood change (9 items)', 'change in concentration level (4 items)', and 'body water retention (5 items)'. The cumulative percent of variance was 63.3%. Regarding the reliability of the scale, its Cronbach's ${\alpha}$ was 0.96. Cronbach's ${\alpha}$ values for these factors ranged from 0.75 to 0.91. Conclusion: The KMSS demonstrated acceptable validity and reliability. Repeated research is needed to measure menstrual symptom experienced by women of variable ages.
