The treatment effects of PCIT can also be demonstrated in school settings, despite the treatment program being lab- or home-based. In a study by Funderburk and colleagues (2009), school assessments were administered at 12 months and 18 months following PCIT. At 12 months, results indicated that children in the treatment group maintained their post-treatment improvements, improving within “normal range of conduct problems” compared to the control group. However, though maintaining improvements with compliance, the 18-month followup indicated some declines into the range of levels before treatment.
