[Parent-child agreement in the health related quality of life (HRQOL) of children with attention-deficit/hyperactivity disorder (ADHD): a longitudinal study].
OBJECTIVE
To assess parent-child agreement on changes over a short-term period of time in the HRQOL of children treated for ADHD over a short period of time, and to compare child and parent ratings of children with ADHD with general population norms.


METHODS
Prospective study in children 6-12 years old with ADHD. Children and parents completed the Spanish versions of the Child Health and Illness Profile-Child Edition (CHIP-CE) before and after 8 weeks of treatment. CHIP-PE scores at both visits were compared using paired t tests and effect sizes (ES), intra-class correlation coefficients (ICC), and scatter plots. Child and parent ratings were compared with CHIP-CE scores for a general population sample.


RESULTS
Thirty-one children and parents were included in the analysis. The highest change between the first and the follow-up visit was on the Risk Avoidance domain both children and parents (effect size [ES]=0.24 and 0.40, respectively). The ICC ranged from 0.44 (Satisfaction) to 0.01 (Risk avoidance). Child self-ratings were close to general population values. All domains of the parent version presented standardized means below the reference values at the baseline visit and closer to the general population norm after treatment.


CONCLUSIONS
This study found poor parent-child agreement and suggests that both ratings should be collected in future studies on the impact of ADHD and treatment effectiveness.
