Elaborating on the causes of criminal behavior can be complex, especially when trying to wrestle with the obvious subjective nature of "criminality" and trying to define the causes of an individual's intent to commit a crime or pursue a criminal lifestyle.

However, when ranked in terms of importance, Antisocial Personality Disorder (APD) is the single most prevalent factor in understanding the root causes of criminal behavior.
Several prominent studies show that APD is a strong predictor of criminal activity and is exhibited frequently among the prison population (up to 50%), according to the Public Health Agency of Canada (2002).
It follows that these studies show a strong connection between the condition and criminality.
For a better understanding of how APD is an indicator for the likelihood of offending, it must be defined.
