Parents' tolerance for the conduct problems of the child with cleft lip and palate.

A standardized questionnaire was used to record parents' ratings of the frequency of conduct problems and their tolerance of the problems. According to parent report, children without facial clefts and children with facial clefts displayed conduct problems with about the same frequency. However, parents of children with facial clefts were significantly more tolerant of problems in their offspring. These data suggest that the social learning environments in the homes may be different for the two groups of children.
