ASPD was also found to correlate with greater substance-related problems compared to those without ASPD (Westermeyer and Thuras, 2005, Goldstein et al., 2007). Thus, our findings that male MA users had higher prevalence rates of ASPD than female users (17.9% vs. 6.2%) is consistent with the broader illicit substance use literature in general and with other studies of ASPD and MA specifically (Lin et al., 2004).
