The process of matching people’s symptoms to pre-established categories of psychological disorders
(DSM). It’s the basis for selecting therapy and making a prognosis.
Multiaxial System of Diagnosing

Axis III Used to record medical disorders.
Axis IV Estimates the severity of stressful life events.
Axis V Estimates the highest level of adaptive functioning in social, occupational, and leisure activities.
