Does the Nonverbal Learning Disabilities (NLD) Scale distinguish between subtypes of pervasive developmental disorder?

The NLD Scale, developed by Rourke in 1993, is an instrument designed to assist in the diagnosis of nonverbal learning disabilities (NLD). The purpose of the present investigation, which uses the NLD Scale, was twofold. The first goal was to evaluate the validity and internal consistency of the NLD Scale, which is a relatively new tool. The second goal was to determine if the NLD Scale could distinguish between individuals from 3 different subtypes of pervasive developmental disorder (PDD): (1) high functioning autism (HFA), (2) Asperger syndrome (AS) and (3) pervasive developmental disorder-not otherwise specified (PDD-NOS). This was done in order to investigate recent findings that the NLD neuropsychological profile is characteristic of persons with AS, but not those with HFA. Next, the PDD groups were compared using one-way between groups ANOVAs and Jonckheere's test of trend on each of the following NLD Scale measures: (1) neuropsychological functioning, (2) academic achievement, (3) social-emotional and adaptive functioning, (4) total scores, and (5) individual questions.
