Predicting pathways of specific language impairment: what differentiates good and poor outcome?
A group of 117 children who met criteria for Specific Language Impairment (SLI) at 7 years of age were reassessed at 11 years of age. The data gathered from both stages were used to identify predictors of good and poor outcome from earlier test assessments. Results of logistic regressions indicated that measures of narrative retelling skills and expressive syntax were the strongest predictors of overall prognosis. This finding persisted when a nonverbal measure was included as a predictor alongside language measures in the regression model. There was found to be a lack of independent predictive contribution of early measures of articulation to later overall prognosis. Demographic factors (maternal education and family income) were not differently distributed across outcome groups. The theoretical and practical implications of the findings are discussed.
