Evaluation reveals enhanced detection of mental abnormalities in infants following screening practice, suggesting practical use.
The purpose of this paper is to evaluate the effectiveness of the mental developmental screening tests, the Ohtu method and DPDQ, in the practical field by comparing the detection rate of mental abnormality after practicing screening tests with the detection rate of it before practicing them. The detection rate differs significantly at p<.001. Before practicing screening tests, mentally abnormal infants, especially mentally retarded infants with unclear medical causes could not be detected. This study shows that even if the mental developmental screening tests now used are imperfect, it is useful to practice them at medical examinations.
