Most of the correctional literature concerns males, obviously, as 90% of inmates are male. The concurrent work, as Wayne was saying earlier, shows that getting your mental health and addictions treatment from the same team works better than farming it out among different providers. Particularly for the people with serious mental illness, the more we can integrate the care with one treatment intervention group, the better. That seems to work for men and for women.
In terms of different models of care, my own experience is that culture-specific programming improves efficacy. Often, people of minority ethnicity or first nations people feel marginalized. Creating therapeutic venues in which their culture is celebrated and given primacy helps them rebuild a sense of self, which puts them in a position in which they are better able to pick up the same therapeutic challenges that everybody else has.
Altering the cultural context within which the same evidence-based practices are delivered improves efficacy. So looking at where you have common cultural groups of sufficient size to permit having some of your programming culturally based would improve the likelihood of its success.
