This study examined preliminary effectiveness of one of the first Project Re-ED (Re-education of Emotionally Disturbed children) residential treatment centers for children. Data were collected at admission, at discharge, and up to 6 months postdischarge. Findings show substantial decreases in problem behaviors and improvements in personal strengths during treatment for children ages 6-12. Despite some deterioration of outcomes in the postdischarge period, improvement compared to baseline continued to be evident at 6 months postdischarge. Multivariate analysis showed that relatively few factors were associated with differential change while in treatment. Younger age, however, was related to more substantial change during treatment and longer length of stay was associated with more positive outcomes by 6 months postdischarge.
