Intellectual disability: a concept in need of revision?

It is suggested that the way the term
intellectual disability is used gives the impression
that it is a discrete entity which
can be diagnosed simply by assessing an
individual’s level of adaptive behaviour
and IQ. It is argued that we are not able to
measure either adaptive behaviour or IQ
with sufficient accuracy. A looser definition
of intellectual disability is suggested,
acknowledging the problems in measurement
and emphasising the need for clinical
judgment.
