According to the DSM-5, if an individual has preoccupations and repetitive behaviors that markedly interfere with functioning, what severity level would this be classified as?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

The correct classification of severity level according to the DSM-5 is indicative of significant challenges faced by the individual. When an individual exhibits preoccupations and repetitive behaviors that markedly interfere with functioning, it implies that their ability to perform daily activities, engage meaningfully with others, or navigate various settings is severely impacted.

In the context of autism spectrum disorder, severity levels help to communicate not just the presence of symptoms but also the degree to which these symptoms affect an individual’s life. A severity level of 3 is classified as requiring very substantial support. This level reflects a situation where the individual experiences profound disruptions due to the intensity and impact of their behaviors and preoccupations, leading to considerable difficulties in various areas such as social interactions, academic performance, and daily living skills.

By contrast, lower severity levels would indicate less impairment and lower support needs. Therefore, the classification of severity level 3 accurately encapsulates the considerable interference observed in the individual's functioning.
