Note:

1

Values displayed are changes from baseline (Δ); Mean (95% CI) are shown.

2

Values displayed are difference estimates (95% CI) and corresponding p-values refer to the between-group difference in family-based interpersonal psychotherapy (FB-IPT, n=15 dyads) as compared to family-based health education (FB-HE n=14 dyads). Models adjusted for children’s sex, baseline age, the baseline level of the outcome, and baseline BMI-z (or baseline BMI or body fat for those outcomes).

*

p <.05 within-condition change.

Social problems assessed with the Social Adjustment Scale. Symptoms of depression assessed with the Children’s Depression Inventory. Symptoms of anxiety assessed with the State-Trait Anxiety Inventory for Children-Trait Version. Disordered-eating assessed as the global score on the Eating Disorder Examination adapted for Children (evaluated at six-month and one-year follow-ups only). BMI, z-score=body mass index standard score for age and sex. BMI=body mass index.
