It is difficult to group female sex offenders by their mental health problems because of the variety of assessment procedures and criteria across studies. Some researchers have, however, found a higher incidence of schizophrenia and developmental delay among female sex offenders than among male sex offenders. Sex offenders of borderline intelligence are usually found in the criminal justice system. These women need education and basic skills training. They should be released to a well-structured environment with practical and emotional support.
Supervision is needed to monitor compliance with non-association and substance use conditions.
It is likely that many predisposed sex offenders would meet the criteria for personality disorder and, under extreme stress, may experience what appear to be brief psychotic episodes. However, few female sex offenders suffer from schizophrenia, bipolar affective disorder or hypomania. Further, those who are psychotic at the time of their offence are usually diverted to the health system, keeping the number of psychotic female sex offenders in correctional systems low. Offenders suffering from mental disorders often require medication, support and education about their sexual behaviour. Supervision should include monitoring medication use and any required non- association with potential victims.
