According to the DSM-5, what is true about autism spectrum disorder (ASD) severity levels?

The concept of severity levels in autism spectrum disorder (ASD) as defined by the DSM-5 emphasizes the importance of understanding individual support needs for individuals with ASD. Severity ratings are primarily used to provide a descriptive framework for how autism manifests in different individuals, helping practitioners, caregivers, and educators understand the degree of impairment and support necessary for each person.

This framework allows for a nuanced view of ASD, recognizing that individuals may exhibit varying degrees of challenges in social communication and restrictive or repetitive behaviors. It is essential to note that these severity ratings are not fixed and can vary across different contexts, meaning that a person may demonstrate different support needs depending on their environment or situation.

The other options do not accurately reflect the guidelines set forth by the DSM-5. Severity ratings do not dictate eligibility for services, as eligibility often depends on broader criteria. Additionally, severity ratings can change over time as individuals grow and develop, demonstrating that the needs for support may evolve. Therefore, the correct interpretation of severity levels focuses on their role in providing a descriptive approach rather than a rigid classification system.
