[Influence of the communication about one parent's cancer on children's suffering]

Factors contributing to children's distress when a parent is affected with a cancer are still insufficiently known. This study aimed at searching for associations between psychosocial distress in children living with a parent suffering from cancer, the severity of parental cancer, the levels of psychosocial distress in both parents and the openness to discuss cancer in the family.

Thirty families encompassing a parent treated for cancer and 54 children aged four to 16 were examined. Each parent's psychosocial distress was assessed by the General Health Questionnaire (GHQ-28) and the distress of the children living within the family by the Child Behavior Check List (CBCL) filled out by both parents. Each parent's communication ability about cancer was assessed by the Openness to Discuss Cancer in the nuclear Family questionnaire (ODCF).

No association was found between children's distress and objective cancer characteristics. Higher externalized disorders scores at CBCL (aggression) were found when the ill parent was the mother (P=0.018). After controlling for cancer parent's gender, CBCL total score and internalized disorders (anxiety, depression) score were higher in families characterized by an "open" style of communication, defined on the parental couple as a whole (respectively p=0.007 and 0.024), such an effect being present only when the ill parent was the mother (interaction effect: p<0.001).

These results underline the importance of family characteristics for understanding the suffering observed in children living with a parent affected with a cancer in comparison with objective cancer characteristics.
