Briefly describe how the DSM-5 diagnosis of autism spectrum disorder differs from corresponding diagnoses in the DSM-IV. How does the revision of the DSM-IV diagnoses relate to the distinction between categorical and dimensional approaches to diagnosis?
What will be an ideal response?
Ans: The DSM-5 uses autism spectrum disorder as a single “umbrella” diagnosis, conceptualized as a continuum. By contrast, the DSM-IV specified three distinct disorders: autism, Asperger’s syndrome, and pervasive developmental disorder. The DSM-5’s notion of a spectrum is essentially an autism dimension or continuum, whereas the DSM-IV divides this continuum into three discrete categories.
