Q

How is the mental illness identified using the DSM05?

Q

What are the imperfections of the DSM?

A
  • Process criticisms (field trials, composition of task force).
  • The lowering of diagnostic thresholds
  • The introduction of new disorders without a clear scientific basis
  • Failure to test/demonstrate validity of diagnostic categories
  • Reification of ‘disorders’
  • Failure to deliver on the promise of neuroscience
  • The reduced ‘reliability’ of many diagnoses

Q

what are the implications of the imperfections of the DSM?

A

Awaits empirical evidence and is yet to play out but some anticipate that:

  • diagnostic inflation and false epidemics

A

Accounts for 47% of disability in developed countries and & 28% of disability in un- (or under-) developed countries respectively.
