This study was carried out in order to find out what prognostic factors affect children with specific language impairment. The subjects were 134 children who were diagnosed as having a specific language impairment at our clinic from 1988 to 1999. They were classified into two subtypes, those exhibiting expressive language delay and those showing receptive language delay. A significant difference between the two groups was seen at each time point and when the whole period of follow up was compared with a Kaplan-Meier analysis and the logrank test.<BR>The expressive language delay group demonstrated significantly better prognosis than the receptive language delay group. Cox's proportional hazard regression model was used to investigate whether any clinical prognostic factors were confounding the underlying catch-up time. Gender and expressive/receptive language development were identified as prognostic factors affecting catch-up time.<BR>Especially, receptive language development was seen as the most important factor.<BR>In conclusion, it is useful for purposes of projecting prognosis to classify specific language impairment into two subtypes according to receptive language development.
