The performance of two screening instruments for pervasive developmental disorders was studied in the total population of children and adolescents with mental retardation between 4 and 18 years (N=1059) in Friesland, a northern province of the Netherlands. Parents completed the ABC, staff completed the PDD-MRS. The screening instruments were related to the ADI-R and ADOS for 184 participants. T...

Introduction Pervasive developmental disorders (PDD) are characterized by social and communication deficits, repetitive and stereotyped behaviours and onset before 3 years of age [1].

The dramatic increment ...
