Development and behaviour of seven-year-old triplets.
The aim of this study was to assess the development and behaviour of 7-y-old triplets, who were followed from delivery to 7 y of age. The McCarthy Scales of Children's Abilities (MSCA) and Achenbach's Child Behaviour Checklist (CBCL) were used to assess and compare development and behaviour in the triplets and in a control group of singletons. The sample included 33 sets of triplets and 33 singletons, all 7-y-olds, and comparable for sex and fathers' social class. The triplets' scores on the MSCA were all within normal range. Although their mean scores for all subtests were below those of singletons, they did not differ significantly. The mean CBCL scores, based on mothers' reports, indicated that the triplets had significantly fewer behavioural problems than the controls. In half the triplet sets, one child stood out as having more behavioural problems than the others.


CONCLUSIONS
Further assessments of the development of triplets are needed; these should be based on larger study samples and should use information from teachers and external observers as well as mothers.
