I'm not entirely sure about that. During that solitary confinement trial, I was surprised to learn that some of the statistics that corrections are keeping aren't the sorts of things I thought. I thought they would have a sense of the prevalence of mental health issues in people coming in. That's something they've more recently been looking at. They weren't able to provide that type of information for women coming into the prison, at least not at the time of that trial.
I think that's really problematic, because how do we assess whether their interventions are working if we don't have a sense of the experience of people with mental health conditions coming in? How do we tell if they're worsening, getting better, or staying the same if we don't understand and we're not taking a holistic look at the person when they're coming into the prison? Mental health is one area in which I think they haven't been doing such a great job at collecting that data. I may be wrong. That data may be collected now, but it certainly didn't seem to be available at the time of the trial this past summer.
I don't know about the rates of recidivism, and whether they're able to aggregate the data across gender, indigeneity, and mental health. Based on the experience with the trial, I would be surprised if it were coming across in that way. It may be available, but I don't know if they're tracking it like that, to be honest. Ivan Zinger might know.
