Behavioural, cognitive, and affective aspects of social functioning of 107
children with a chronic illness were studied. The aim of the study was twof
old. (I) to describe peer interaction of children with a chronic illness in
comparison with normative data of healthy children; (2) to examine whether
peer interaction was related to the illness characteristics physical restr
ictions and pain. Peer interaction was assessed with measures of social act
ivities (CBCL), parent-reported social skills (CABS), child-reported social
skills (MESSY), social self-esteem (SPPC), and social anxiety (SASK). Resu
lts showed no differences between diagnosis groups, suggesting that the soc
ial consequences of chronic illness are not diagnosis specific. Compared wi
th healthy norms, chronically ill children reported less aggressive behavio
ur. The parent-report measures suggested a similar trend. Children with chr
onic illness also tended to display more submissive behaviour than healthy
norms: as perceived by their parents. With regard to illness characteristic
s. both physical restrictions and pain were associated with restricted soci
al activities, but not with other measures of social peer interaction. Chil
dren who display submissive behaviour and children who are restricted in th
eir social activities should receive extra attention because they are espec
ially vulnerable for problems in their social development.
