Abstract

The purpose of this study, as a following study of the pilot test which develop preschool children's daily stress scale, is to develop final items for scale development and verify its reliability and validity. From the pilot test, "experience anxiety-distress*7, "hurt pri.de"，and "encounter criticized-violent situation" were found as three factors and 31 items were already selected.. Using the same method as the pilot test, the finally selected final 31 items were tested by 550 preschool children (age 3-6). The teachers of those children's were asked to observe their students' behavior and provide their professional evaluation. The reliability of the scale was the total a =.80 and the calculation for each factor was .62, .68, and .66, respectively. To verify the validity of the scale, content validity, construct validity, and criteria-related(concurrent) validity were tested. The content validity was verified several times by professional. Factor analysis, t-test were used to verify construct validity and factor analysis was proved to be similar to that of the pilot test which resulted in the same three factors and the number of items was further adjusted to 23, and the total explained-variable value was 79.73%. Inter-factor correlation for the three factors was measured at .45, .52, and .26, respectively. To verify the content validity of the scale, the t-test was conducted between a group of/ children from normal-family preschool children group and a group of children from single-parent preschool children group, and the difference between a group of children who showed normal-children group and a group of children who showed clinical-children group, and the result was significant(p<.001, p<.01). This study was significant in that this was the first preschool children's daily stress scale developed yet in Korea with the direct response and input from Korean preschool children. Further study and research to re-verify the scale developed by this study may be necessary. Also, more field testing of the scale developed by this study through a greater number of preschool children is needed to achieve the standardization of the newly developed scale.
