The purpose of the study was to help identify interventions necessary to suitably address the issues and needs of maximum-security women and facilitate the reduction of maximum-security classification of female offenders. This article is limited to describing the heterogeneity of this population and to presenting some points regarding security classification reduction identified by the women offenders. In February 1998, voluntary interviews were conducted with 14 of the 15 women in the non-Aboriginal maximum-security population. Data for the study were also obtained from discussions held with 20 Correctional Service staff in personal interviews and focus groups, as well as from supplementary meetings with psychologists and program delivery officers. One of the most important findings was the heterogeneity of this maximum-security female population. This population is most readily differentiated on the basis of the following three identifiable but not mutually exclusive sub-populations: those with antisocial behavior and criminal attitudes; those with special needs that result from serious emotional and mental health issues; and those with special needs that result from cognitive limitations and basic skill deficits. Findings are also presented on security classification-reduction issues. Findings from this research support an appreciation of the complexity of the challenges in understanding and managing non-Aboriginal maximum-security female offenders. The research also provides insight regarding how to assist these women in reducing their security classification level. 7 notes
