Abstract
In a sample of 243 children (119 males and 124 females) aged between 36 and 72 months, students from public and private institutions, was evaluated the psychometric properties of Child Neuropsychological Maturity Questionnaire CUMANIN, post their adjustment and normalization. These findings can indicate that the instrument has good internal consistency and is able to discriminate between age groups, resulting in higher yields as age advances. There were no differences in scores by gender. Factors such as socioeconomic status and type of educational institution attended by the infant determined differences in the results. We concluded that the Child Neuropsychological Maturity Questionnaire CUMANIN is a reliable and valid instrument for the assessment of neuropsychological maturity construct in preschool population.
