Background:
It is important for children to maintain high self-perceived competence and self-esteem, and there are few measures to evaluate them through elementary to junior high school days in Japan. To evaluate psychometric properties of the Children's Perceived Competence Scale (CPCS).
Methods:
Data were collected from 697 elementary school and 956 junior high school students. Some of these students completed measures for construct validity, whereas others repeated the CPCS.
Results:
The results demonstrated the three-factor structure of the CPCS: cognitive (nine items), social (eight items) and physical (nine items). Factorial invariance was confirmed between elementary and junior high school students, as well as between boys and girls. Construct validity was excellent. Scores on the cognitive, physical and general self-worth domains declined with increasing age. Boys scored significantly higher than girls on physical and general self-worth domains.
Conclusions:
The CPCS is a valid and reliable measure of perceived competence in Japanese children aged 6-15 years. The CPCS may be applied to students from elementary through junior high school days as a measure of self-perceived and psychological state in Japan.
