Parent-child agreement on health-related quality of life: the role of perceived consequences of the child's chronic illness.

Objective: We aimed to assess the parent-child agreement on various domains of health-related quality of life (HRQoL) in a Hungarian pediatric sample. We examined the associations of demographic, illness-specific factors and the perceived consequences of the illness with the parent-child disagreement.

Design: A cross-sectional study was carried out with child-parent pairs in a heterogeneous pediatric sample (n = 259).

Outcome Measures: Child and parent versions of Kidscreen-52 and the consequences scale of the Revised Illness Perception Questionnaire (IPQ-R) were applied. We used intraclass correlation coefficients to measure agreement. We computed directional discrepancies as dyadic indexes and applied them in multinomial regression analysis to identify factors influencing agreement.

Results: Agreement between children and parents on the KIDSCREEN-52 instrument was moderate to good (ICC = 0.41 to 0.66). Significant (p < 0.005) parent-child disagreement was observed on 6 out of 10 dimensions of HRQoL: Parents rated their children's well-being lower on Physical Well-being, Psychological Well-being, Parent Relations and Home Life, Social Support and Peers, and Financial Resources scales and rated higher on Moods and Emotions compared to child-reported HRQoL. Both parent's and child's higher perceived illness consequences made disagreement significantly more likely on various domains.

Conclusions: Direction of disagreement may draw attention to potentially vulnerable domains of the child's well-being, like moods and emotions and self-perception.
