I'm not in a position, actually...because I am not familiar on the ground with their programs and how they are delivered. I am familiar with attempts to develop models; for example, in the treatment of women with substance use and mental health issues some good models have been developed. But I am not sure how well disseminated or available those programs are to people in the correctional system.
I think the understanding of the need to offer concurrent treatment is well established with the staff who do this work in correctional services, but I am not sure about the prevalence of the programs or how they are actually delivered.
