Research note: temperament and behaviour in six-year-olds with recurrent abdominal pain: a follow up.

Dimensions of temperament and behaviour were measured in a group of infant school children with recurrent abdominal pain and in a control group. Children with recurrent abdominal pain were temperamentally more difficult than those without, and in particular, girls were found to have a more irregular temperamental style and boys to be more likely to withdraw in new situations. Temperamental differences were more persistent than the abdominal pain itself. There was little difference behaviourally between the groups. It is hypothesized that abdominal pain represents an interaction between a vulnerable temperamental style and environmental stresses.
