The aim was to evaluate a questionnaire for parents concerning their school-aged children's global maturity level. Immature children (n = 29) as reported by their parents were compared to a control group (n = 68). Immaturity was linked to a reduced general knowledge, a childish body appearance, problems with the fine motor function and problems with peers. The index group also had on average a lower test result in total score of the Wechsler Intelligence Scale for Children and more commission errors in the Continuous Performance Test, both test results indicating a lower mental age.
