Parent reports of child behavior problems: bias in participation.

This paper compares the characteristics of 274 children whose parents agreed to provide information about their children's functioning in research with children whose parents did not. Parents had provided permission for child participation in school-approved research. Measures included self-, peer, teacher, and parent ratings. Parents of minority children were less likely to participate than parents of nonminority children. Among nonminorities, children of parent participants were viewed as more socially skilled and liked by their peers; teachers rated them as having less attention problems, less depression, and better academic skills than children of nonparticipating parents. Among minorities, no differences emerged. Implications for research involving the use of parent ratings are discussed.
