Strengths of the definition:
Matches sufferers' perceptions - as most people seeking clinical help
believe that they are suffering from psychological problems that
interfere with the ability to function properly, it supports the
definition
Assesses degree of abnormality - as the GAF is scored on a continuous
scale, it allows clinicians to see the degree to which individuals are
abnormal and thus decide who needs psychiatric help
Observable behaviour - it allows judgement by others of whether
individuals are functioning properly, as it focuses on obeservable
behaviours
Checklist - the definition provides a practical checklist individuals can
use to assess their level of abnormality
Personal perspective - it recognises the personal experience of sufferers and
thus allows mental disorders to be regarded from the perception of the
individuals suffering them
Limitations of the definition:
Abnormality is not always accompanied by dysfunction -
psychopaths, people with dangerous personality disorders,
can cause great harm yet still appear normal
Subjective nature of the features of dysfunction - although GAF
measures levels of functioning, it doesn't consider behaviour from
an individual's perspective
Normal abnormality - there are times in people's lives when it is
normal to suffer distress, like when loved ones die
Distress to others - behaviour may cause distress to other people
and be regarded as dysfunctional, while the person in question
feels no distress, like Stephen Gough, the naked rambler
Personally rewarding abnormality - an individual's apparently
dysfunctional behaviour may actually be rewarding. For example,
a person's eating disorder can bring affection and attention to
others
Cultural differences - what is considered 'normal functioning' varies
from culture to culture and so abnormal functioning of one culture
should not be used to judge people's behaviour from other cultures
and subcultures
