Intellectual disability is characterized by significantly subaverage functioning. What is a key factor that must be considered in this diagnosis?

In diagnosing an intellectual disability, it is crucial to establish that the deficits in intellectual functioning are not attributable to or better explained by other disabilities. This means that if an individual has an intellectual disability, their functioning must be evaluated in isolation from any other coexisting conditions or disabilities that could contribute to their cognitive challenges.

This approach ensures that the diagnosis accurately reflects the individual's intellectual capabilities rather than being influenced by additional factors that might complicate the assessment. For instance, if a person also has a learning disability or a severe emotional disturbance, those factors need to be distinguished from the intellectual impairment to ensure correct identification and support strategies can be implemented effectively.

By focusing on the necessity for deficits to stand alone, practitioners can provide a clearer understanding of the individual's unique needs, allowing for tailored interventions and supports that address the specific aspects of intellectual disability without the interference of other conditions.
