Hi Marion,
A similar effort in a "gang neighborhood" happened in the Southeast Bronx, in the 1970's, when the "Young Lords" accompanied interns/residents who made house calls in that neighborhood (100,000 heroin addicts at that time), and the Young Lords also ran the detox program at Lincoln Hospital. Social Psychologist Phil Zimbardo grew up there, and has written about it (He also ran the Stanford [University] Prison Study/Experiment in the early 70's).
The Council of State Governments Criminal Justice/Mental Health Consensus Project may have some info pertaining to Juvenile Detention Centers. Possibly the SPSCOT [State Personnel Systems Coalition on Trauma] Listserve may be of help. Some of their membership are also members of ACEsConnection.
Susan Lawrence, M.D. at the Catalyst Foundation, has noted ACE's in her book, "Creating A Healing Society:...', and she wrote about challenges and outcomes with an after school program, as well as some reference to the "Trauma-Informed" Honor Prison in California (Gang membership is renounced in that prison). I don't know if she used resiliency cards in the after school program,
The Data Center in Oakland, Cal. does "Impact Research for Social Justice" and has done a number of Juvenile Justice initiatives with kids in California and elsewhere. Urban Information Interpreters at the University of Maryland Library School did a few projects involving kids that age--one on how to hang out on a stoop on rent collection day, note the license plate of rent collectors, then they taught the kids how to track corporate ownership from the license plate of slum landlords and to collaborate with community organizers.
Sorry this isn't more specific to your request, but I hope its a start.
