Classifying Psychological Disorders
It’s important to have a system for classifying disorders for diagnosis and treatment.
Disorders were first classified based on their presumed causes.
Today, psychologists use the DSM-IV to classify disorders. DSM-V: Diagnostic and Statistical Manual of
Mental Disorders; 5th edition (first published in 1960)
