The increasing proportion of girls in the juvenile justice system has prompted courts to develop gender-responsive services. The present study examined data from a mid-sized county juvenile court to examine the effects of a group home intervention for girls. The study compared group home participants (n = 172) with girls who did not receive group home treatment (n = 814) using propensity score matching (PSM). Girls who received group home treatment were significantly less likely to re-offend in the 2-year follow-up period. Policy and practice implications for gender-responsive services as well as future directions for research are discussed.
