The purpose of this study was to investigate how experiencing activities to foster self-esteem affects young children s response on daily stress and whether those effects continue. For the purpose, following research questions were set up: 1. How does experiencing activities to foster self-esteem affect young children s response on daily stress situation? 1-1. How does experiencing activities to foster self-esteem affect young children s response on criticized-violent situation? 1-2. How does experiencing activities to foster self-esteem affect young children s response on anxious-distressful situation? 1-3. How does experiencing activities to foster self-esteem affect young children s response on pride-hurt situation? 2. Do the effects of experiencing activities to foster self-esteem continue? Participants for this study were 60 five-year-old children attending private kindergartens in Chungju, Chungbuk, among whom 30 children (17 boys and 13 girls) were assigned to the experimental group while 30 children (19 boys and 11 girls) were assigned to the control group. The children s mean age was five years and eight months, consisting of five years and eight months for the experimental group(boys: five years and nine months, girls: five years and eight months) and five years and seven months for the control group(boys: five years and nine months, girls: five years and six months). The instrument was Yeom(1998) s Korean Preschool Daily Stress Scale(KPDSS) And Activities to foster Self-esteem, which was reconstructed by Han(2009), were conducted for 12 weeks by three or five times per week, and totally 56 times per child. The means and standard deviations of young children s daily stress were first computed by data collection time(pre, post, and following test). In order to detect group differences of pre- and post-test scores, a series of t-tests were run on the incremental scores that were computed by subtracting pre-test score means from post-test score means from following test score. And repeated two-way ANOVA between experimental and control group were performed to find out the continuous effects of experiencing activities to foster self-esteem. Results of this study were as follows. First, there was significant group difference of young children s response on daily stress situation by experiencing activities to foster self-esteem between the experimental and control groups. And there were significant group differences of young children s response on criticized-violent situation and anxious-distressful situation among daily stress situations. Second, the effects of experiencing activities to foster self-esteem had continued after 10 weeks of experiencing activities to foster self-esteem.
