%0 Journal Article %T Validity and Reliability of the Interaction Rating Scale between Children (IRSC) by Using Motion Capture Analysis of Head Movement %J Public Health Research %@ 2167-7247 %D 2012 %I %R 10.5923/j.phr.20120206.06 %X The aim of this paper was to validate the Interaction Rating Scale for Children (IRSC) as an evidence-based practical index of social skills. Twenty 5¨C6-year-old preschool students participated in our study. Participants were required to complete a 5-minute interaction session and were evaluated using the IRSC. A motion capture machine, based on an ecologically valid interaction within a candy-distribution setting, monitored participants¡¯ head movements. Results indicated a moderately high correlation between IRSC scores and head movements. When cooperation was high, the ¡°Pitch¡± was higher (r = 0.548, p < .05) and the ¡°Yaw¡± was lower (r = -0.685, p < .01). When self-control was high, the ¡°Pitch¡± was lower (r = -0.576, p < .01).The IRSC is able to measure social competence with high validity. Thus, the IRSC is a helpful tool for understanding the development of peer relationships. %K Interaction %K Peer %K Children %K Evaluation %K Scale %U http://article.sapub.org/10.5923.j.phr.20120206.06.html
