Objective: To assess psychosocial concerns of families with familial h
ypercholesterolaemia. Methods: One-hundred-and-fifty-four single or pa
irs of parents of children age 6-16 years responded to a specifically
designed questionnaire. One child from each family was interviewed. Re
sults: Eleven percent of parents thought that their quality of life wo
uld have been better had they not known about the disease. None agreed
totally that they wished that the diagnosis had not been made. Howeve
r, 20% reported familial conflicts and 8% that their child's emotional
or social life had been adversely affected. Conflicts and adverse eff
ects were associated with higher scores on the Child Behaviour Checkli
st (CBCL). Among the children, worry about cardiovascular disease (aff
irmed by 22%) was related to male sex and CBCL score. Relevance: Most
families do not indicate that they have experienced psychosocial probl
ems due to familial hypercholesterolaemia. Parental ratings of the chi
ld's behavioural adjustment may identify vulnerable children.
