Specific Changes Per Diagnostic Category in DSM-5
Neurodevelopmental
1. Intellectual Disability (Intellectual Developmental Disorder) no longer relies on IQ used as
specifier because it is the adaptive functioning that determines levels of support required.
Moveover IQ measures are less valid in the lower end of the IQ range. It is still accepted that
people with intellectual disability have scores two standard deviations or more below the
population mean, including a margin for error which is generally +5 points. Thus on tests
with standard deviations of 15 and mean of 100 the score for mild would involve 65-75 (70+5)
2. Asperger's Syndrome is lumped into Autism Spectrum since it is at the milder end of the
Spectrum. Also childhood disintegrative disorder, Rett's disorder and pervasive
developmental disorder not otherwise specified are also now incorporated into the Autism
Spectrum Disorder.
3. Autism Spectrum Disorder is now characterized by deficits in two domains: 1. deficits
in social communication and social interaction and 2. restricted repetitive patterns of
verbal and nonverbal communication.
Schizophrenia and Other Psychotic Disorders
1.Changes for Criteria A for Schizophrenia were made: 1) elimination of the special

at least one of the Criterion A symptoms must be delusions, hallucinations, or
disorganized speech.
