In this study we evaluated the relation between parents' reports of their usual procedural behavior, their observed behavior, and children's coping and distress during immunization procedures. Fifty-five children, 4 to 6 years old, and their parents participated in the study. Prior to the children's immunizations, the parents provided reports of the therapeutic behaviors they typically engage in during their children's painful medical procedures. The immunization procedure was videotaped, and parent and child behaviors were later coded with the Child-Adult Medical Procedure Interaction Scale. Results indicated that parents overestimate the quantity of their therapeutic behaviors and that no relation exists between parents' reports of their behavior and their actual behavior during children's immunizations. Further, parents' reports of their behavior were unrelated to their children's distress or coping. However, parents' behaviors were significantly related to children's distress. These findings suggest that preoperative parent self-report is not a valid index of actual behavior during children's acute painful procedures. Therefore, parent behavior, rather than parent report, should be used to determine their need for training in how to help their children cope with painful medical treatments.
