| Research Abstract |
The high-risk infants require early intervention and family support. We have conducted a longitudinal follow-up study on very low-birthweight infants. We are interested in the outcome of follow-up and cognitive development of high-risk infants using different psychological assessment tests. The purpose of this longitudinal study is to clarify the characteristics of cognitive development in high-risk infants without major handicaps until school age on follow-up. We also aimed to clarify the use of a psychological test battery for the assessment of Learning Disabilities, Attention Deficit Hyperactive Disorder, and High-function Pervasive Developmental Disorder as early on age as possible. The cognitive assessment was administered to children at 4 years of age using the Tanaka-Binet Intelligence test and at 6 years and 9 years of age using the WISC-III and Draw-A-Man test. Very lowbirthweight infants even with score more than the average value, found it difficult to achieve passing scores for items such as verbal tasks abstracting, and definition of object at 4 years. The results of multiple regression analysis suggested that birth weight and the number of prenatal risk scores did not contribute to their cognitive development scores at 6 years. Very lowbirthweight infants showed higher scores than extremely low-birthweight infants on performance abilities. At 6 years of age, WISC-III represented for the cognitive development, DAM represented for emotional behavior, and motor ability. At 5 to 6 years, high-risk infants increased scores of verbal areas and perceptual organization, and visual-motor integration. At 6 to 9 years, the age of cognitive development of high-risk infants, there was no almost change using the assessment test. As for cognitive development, verbal ability is developed by 6 years of age, and performance abilities after that. Additional research is needed to on the use of psychological assessment and to determine the effect of early intervention.
