All participants included in analysis following multiple imputation

Each moderator was tested in a separate regression model.

Betas are the coefficient of the three-way interaction term in the mixed effects regression model (moderator X treatment arm X time). The PTSD model was a linear mixed effects model and the functioning model was a generalized linear mixed effects model with a log link.

Someone else” includes stepparents, grandparents, siblings and “other caretaker”. No one” accounted for <2% of the population and so was combined with someone else category.

Model estimated only on TF-CBT sample. Beta is coefficient of two-way interaction of parent participation (coded as 1 if participated and 0 if not) and time.
