The overall prevalence of Antisocial Personality Disorder in community samples is about 3% in males, and about 1% in females. Prevalence estimates within clinical settings have varied from 3%-30%, depending on the predominant characteristics of the populations being sampled. Even higher prevalence rates are associated with substance abuse treatment settings and prison or forensic settings.
APD has a chronic course but may become less evident or remit as the individual grows older, particularly by the fourth decade of life. Although this remission tends to be particularly evident with respect to engaging in criminal behaviour, there is a likely to be a decrease in the full spectrum of antisocial behaviours and substance use.
APD is more common among the first degree biological relatives of those with the disorder than among the general population.
