Three- to 7-year olds were observed in their day cares to determine the prevalence and nature of incidents of everyday pain (e.g. bumps, cuts, and scrapes). An observational checklist was used to record information on the behavioral responses of child and caregiver. The checklist showed excellent interrater reliability and supported the validity of the pain measure used. No age or sex differences in the incidence or severity of everyday pain were found. However, girls engaged more often in distress responses and received more physical comfort from adult caregivers. It was concluded that girls have a vocal response style which elicits responses from adult caregivers. No significant effect of age was found on intensity or duration of distress or on adult response, but frequency of help-seeking behaviors was found to decrease with age. Limited effects of age may be due to the age range restriction of 28-81 months. Analyses of temperment indicated that less adaptive children were more agitated prior to a pain incident. Analysis of behavioral context demonstrated that larger groups of children display a higher level of activity and individuals in the group display higher levels of agitation. Personal control of the child during a pain incident decreased within larger groups and increased with a high level of activity. Finally, it was found that children who experienced 'booboos' most often also responded to them most strongly, suggesting that increased exposure to this type of pain may lead to sensitization, rather than desensitization.
