Gender differences in prevalence rates of depression have been widely reported across the studies reviewed (Brecht et al., 2004; Zweben et al., 2004; Yen and Chong, 2006; Glasner-Edwards et al., 2008; Mahoney et al., 2008). These data suggest a higher rate of depressive disorders in female MA abusers compared to males. In contrast, the evidence for gender differences in psychosis is less compelling. However, despite the differences in sampling methods across studies, our findings on gender differences are consistent with those reported by Chen et al. (Chen et al., 2003) in that a greater percentage of men met criteria for MA-induced psychosis compared to women. Our study extends those findings in that we report a selective gender difference in MA-induced delusions, but not MA-induced hallucinations.
