Note. PERQ = Parental Emotional Reaction Questionnaire, CES-D = Center for Epidemiologic Studies.

Depression Scale.

d₁ = calculated based on differences between T1 and T3 in the TAU-condition: $\frac{TAU T 1 - TAU T 3}{SD TAU T 1}$ .

d₂ = calculated based on differences between T1 and T3 in the TF-CBT-condition: $\frac{TFCBT T 1 - TFCBT T 3}{SD TFCBT T 1}$ .

d₃ = calculated based on differences between the two conditions at $T 3 : \frac{TAU T 3 - TFCBT T 3}{SD pooled}$ where $SD pooled = \sqrt{\frac{(n_{1} - 1) S D_{1}^{2} + (n_{2} - 1) S D_{2}^{2}}{n_{1} + n_{2} - 2}}$ .
