The Discriminant Predictive Validity of the Reynell Developmental Language Scales.

Peer reviewed

Hagtvet, Knut A.; Hagtvet, Bente E. – Scandinavian Journal of Educational Research, 1990

The discriminant validity of two subscales of the Reynell Developmental Language Scales (RDLS) was investigated using data from 225 children given the RDLS at age 4 and the Illinois Test of Psycholinguistic Abilities at age 5. Results support the hypothesis; the RDLS scales measure distinct but correlated language abilities. (SLD)
