Treatment Outcomes

Treatment Outcomes for Children’s Intensive Outpatient Program (IOP)


As of July 2016, six children (4 boys, 2 girls) ranging in ages 11 to 17 have been treated in our IOP. The average length of a full IOP program was 91 days (3 months) and ranged from 58 to 115 days (2 to 4 months). The average number of session hours per week was 13 and ranged from 9 to 21 hours.

At the outset of their IOP program all 6 children were unable to attend school because of the severity of their OCD. Of the 5 children who completed the program, 4 were able to achieve full time school attendance and 1 achieved part time school attendance by the end of the program. The graph below shows the average OCD severity score as measured by the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS) at the start and end of the program. Data come from the 4 children who both completed the program and were given the CY-BOCS at both the start and end of the program. As can be seen, the average child began treatment with severe-to-extreme OCD symptoms and ended the program with moderate OCD symptoms. A reduction in CY-BOCS scores of at least 25% indicates a significant response to treatment while a reduction of at least 45% to 50% or a CY-BOCS score of 14 or below indicates remission of OCD1. Based on these criteria 3 out of 4 children were treatment responders by the end of the program, with 1 of these 3 also achieving full remission. The 1 child who did not meet response criteria by the end of the IOP program met treatment response criteria after continued sessions in regular outpatient treatment.
