Advantages of the dsm l.jpg
Advantages of the DSM (DSM-IV-TR)

  • When used correctly it improves the reliability of the diagnosis making it more accurate.

  • Creates uniformity among clinicians

  • Correct labeling of the disorder may help people identify the source of their condition that may lead to proper treatment.

Limitations of the dsm l.jpg
Limitations of the DSM (DSM-IV-TR)

  • May foster over diagnosis.

  • May increase risk of creating self-fulfilling prophecies.

  • Label will follow the individual.

  • May confuse serious mental disorders with normal problems.

  • Diagnoses reflect prevailing attitudes and prejudice.

  • Create illusion of universality.
