According to a new study by the San Francisco-based Young Minds Advocacy Project (YMAP), as many as 70 percent of the kids in California’s juvenile detention centers are in need of mental health care, and most of them are not getting it. Patrick Gardner, YMAP’s founder and one of the report’s authors, says many of these youth would not be in detention in the first place if there were more home and community-based mental health services available.
