Why are adaptive behavior skills important in diagnosing an intellectual disability?

• A. They measure reading ability
• B. They reflect daily living skills and social functioning
• C. They measure hearing ability
• D. They measure memory

Answer: (B)

Adaptive behavior skills measure how well a person handles everyday tasks and social interactions—things like daily living skills, communication, safety, and practical problem solving. In diagnosing an intellectual disability, it’s essential to look at these real-world abilities because a person’s cognitive test score alone doesn’t show how well they function day to day. If someone has a lower IQ but can manage self-care, money, transportation, and social expectations, they may function independently; if someone has poor adaptive skills, even with average cognitive abilities, they may need support. So adaptive behavior tells us how the cognitive limitations translate into daily life and independence, which is central to the diagnosis. The other options focus on reading, hearing, or memory—cognitive or sensory domains that don’t directly capture how a person operates in everyday settings.
