Girls Study Group: Understanding and Responding to Girls’ Delinquency.

The study, which was conducted by the Girls Study Group established by the U.S. Justice Department's Office of Juvenile Justice and Delinquency Prevention (OJJDP), found that 73 of the 143 instruments reviewed showed favorable gender-based analysis or provided gender-based development. Seven instruments were assessed as "unclear" (produced mixed or inconsistent gender-based performance information); eight instruments were rated "unfavorable" (yielded negative gender-based performance information); and 55 instruments were rated as "unknown" (lacked gender information). Of the four categories of instruments reviewed - risk and risk/needs instruments, global needs assessment instruments, substance abuse instruments, and mental health instruments - the mental health instruments were most sensitive to gender concerns.
