Gender Differences in Criminality: Bipolar Disorder with Co-occurring Substance Abuse

Outpatient interviews to collect criminal history data were conducted with 55 women and 77 men who had the dual diagnosis of rapid-cycling bipolar disorder with co-morbid substance abuse disorders (DD-RCBD), to ascertain gender-related similarities and differences.

Men with DD-RCBD were more likely to have committed a felony and had a trend of committing more misdemeanors. Although women with DD-RCBD were less likely to have a criminal history than their male counterparts, they were far more likely to have a criminal history than were women in the general population.
