['To assess whether use of a parent questionnaire, the Child Development Review (CDR), before health maintenance examinations (HMEs) increases parent identification and increases resident discussion and documentation of behavioral issues for toddler and preschool-aged children.', 'Quasi-experimental design using convenience samples with comparisons before and after questionnaire implementation.', 'Children 15 to 47 months of age and their parents attending a hospital-based, primary care clinic serving a low-income population, and the residents caring for them.', 'Participants were enrolled into early control, concurrent control, and intervention groups. All parents completed an exit interview about 9 behavioral issues and were asked if they had discussed these issues with the doctor. Before the visit, the intervention group parents completed the CDR, which was available for the residents to review. Information from the CDR and exit interview, and resident documentation were compared for control and intervention groups.', 'There were 122 intervention and 135 control group HMEs. Parents using the CDR identified more behavioral issues for their children at the exit interview (median, 2.0 vs 1.0, P =.01). The 6 issues on both the CDR and the exit interview accounted for this increase. Intervention group parents reported discussion of more behavioral issues (median, 2.0 vs 0.0, P <.001). Discussion increased for all issues. Documentation was not increased for the intervention group.'] Does use of the child development review increase residents ' discussion of behavioral problems?
