Pervasive developmental disorders are best described as:

Pervasive developmental disorders are best described as:

• A. ASD
• B. A developmental disorder in which many areas of functioning are affected
• C. Childhood Disintegrative Disorder
• D. Asperger Disorder

Answer: (B)

Pervasive developmental disorders are defined by widespread impairment across multiple areas of development, not just a single skill. This means challenges show up across communication, social interaction, and often behavior or interests, affecting overall functioning. That broad, cross‑domain impact is what the term “pervasive” conveys, making a general description of “a developmental disorder in which many areas of functioning are affected” the best fit for the category. The other options point to specific disorders within the umbrella (like autism spectrum conditions or particular named disorders), which don’t capture the overarching, multi‑domain nature of pervasive developmental disorders as a group.
