Relation of global ratings of functioning with behaviour and development in delayed and disturbed preschoolers

Ratings on the Global Assessment Scale for Children (GASC) were assessed in relation to a battery of objective developmental and behavioural measures. Children aged three to six years (N = 55) attending a day treatment program for developmental delays, language disorders, and behavioural and emotional problems comprised the sample. A battery of tests was administered to the children. Parents and teachers completed standardized questionnaires to measure developmental, behavioural and emotional problems. The results indicated that the GASC score correlated significantly with child developmental level, impulse control, and with teacher ratings of social withdrawal. The GASC was unrelated to ratings of behavioural problems. Ratings on the GASC also were highly consistent over time. These results are discussed with respect to the strengths and limitations of using global ratings with preschool children.
