Epidemiology

The estimated lifetime prevalence of ASPD amongst the general population falls within 1% to 4%, skewed towards 6% men and 2% women. The prevalence of ASPD is even higher in selected populations, like prisons, where there is a preponderance of violent offenders. It has been found that the prevalence of ASPD among prisoners is just under 50%. According to one study (n=23000), the prevalence of ASPD in prisoners is 47% in men and 21% in women. Thus, with only 27-31% of patients with ASPD seeing an improvement in symptoms over time, statistically around one third (33%) of male prisoners will not see any improvement in their symptoms, and are thus essentially prognostically hopeless. The corresponding percentage of female prisoners with statistically no chance of improvement in symptoms is around 15% or roughly one in six. Similarly, the prevalence of ASPD is higher among patients in alcohol or other drug (AOD) use treatment programs than in the general population, suggesting a link between ASPD and AOD use and dependence. As part of the Epidemiological Catchment Area (ECA) study, men with ASPD were found to be three to five times more likely to excessively use alcohol and illicit substances than those men without ASPD. There was found to be increased severity of this substance use in women with ASPD. In a study conducted with both men and women with ASPD, women were more likely to misuse substances compared to their male counterparts.
