OBJECTIVES: The current study aims to explore children’s with cancer and parents’ illness perceptions and their impact on children’s generic and modular quality of life (GQoL/MQoL). METHODS: Children with cancer aged from 8 to 12 years old (N=39) and their parents (N=39) completed the Brief Illness Perception Questionnaire (Broadbent et al., 2006) and a socio-demographic questionnaire. The Quality of Life Systemic Inventory for Children - Module for Cancer (Missotten et al., 2008) was also administered to children. RESULTS: Concerning dimensions of cancer perceptions, “consequences” reported by children and “personal control” by parents are significant predictors of the children’s GQoL: they explain 42% (β=.66; p=.00) and 12% (β=-.32; p=.05) of the variance, respectively. Children’s perceptions about illness “consequences” and parents’ perceptions about illness “implications” are significant predictors of the children’s MQoL, explaining 52% (β=.73; p=.00) and 11% (β=.37; p=.02) of the variance, respectively. CONCLUSIONS: Findings support the hypothesis that children’s and parents’ cancer perceptions may have a different impact on children’s QoL. A better knowledge about the influence of children’s and parents’ illness perceptions on QoL contributes to design intervention to promote QoL among paediatric cancer patients.
