Clinicians using this definition can use the ‘Global Assessment of Functioning Scale’ to help make a more objective diagnosis. The ‘Global Assessment of Functioning Scale’ is used by clinicians to rate an individual’s social, occupational and psychological functioning and is scored on a continuous scale. This is a strength because the scale allows clinicians to clearly judge the degree to which an individual is abnormal rather than just using their own opinion/judgment which would lead to a more reliable and valid diagnosis.
Failure to functionadequately: conclusion
Reliability or validity of diagnosis is not guaranteed with this definition. This is a limitation because it may lead to an individual being unnecessarily labelled as abnormal which can have a negative stigma attached to it. It could also lead to them receiving unnecessary treatment such as drugs that can have negative side effects.
