  1. ns = not significant (p > .10).
  2. Dependent variables for parents’ raw scores were the six generic HRQoL scales, weight-specific HRQoL and weight complaints measured at four time points: pre- and post-treatment, at follow-up 1 and follow-up 2; for parents’ and children’s z-scores as well as for children’s raw scores dependent variables were the six generic HRQoL subscales at the four time points.
