Abstract
We developed a scale to assess time management by children and evaluated its reliability and validity. We conducted a survey in 285 children and tested internal consistency and criterion-related validity. Factor analysis indicated that children's time management consisted of two types of time use: 'establisyment of life rythm' and 'setting goals and priorities.' The two types of time management showed a positive correlation with perseverance and negative correlations with apathy, moodiness, and anger.
These results indicate that the time management scale for children has a certain level of reliability and validity. In the future, using the time management scale for children, it will be possible to examine how the time management of children affects various situations such as school life.
