Failure to function adequately
• By using practical criteria of adequate functioning, mentally healthy people are judged as being
able to operate within certain acceptable limits.
• Abnormality judged as inability to deal with the demands of everyday life and living independently
in society – washing/eating/working/socialising
• Behaviour is maladaptive, irrational or dangerous
• behaviour causes personal distress and distress to others.
