A Comparison of Methods of Increasing Parental Consent Rates in Social Research

Previous research on children requiring written parental consenthas indicated that this requirement reduces samples to halfthe size they might otherwise be and results in overrepresentationof whites and underrepresentation of blacks. Within the courseof a four-year study, four methods were utilized to increaseparental consent rates, particularly for black students. Allmethods increased consent rates. Providing an incentive to theparents increased consent rates significantly more for the whitestudents than for the black students, while communication withthe children and incentives to the children resulted in consentrates which were more similar for the two racial groups. Communicationwith the parents was the most effective method for both blackand white children, but was also the most time consuming.
