This report deals with parents who either drop out or continue to cooperate with procedures for identification of problem children. Some suggestions are made regarding measures for identifying dropouts and continuers in mental health agencies. These suggestions are based on data collected over two years of time while families were being recruited during the conduct of a clinical research project involving the identification of young discipline-problem boys. The results of a preliminary report were combined with results of data collected during the project's second year. Dropping out or cooperative behavior by parents was predicted from early reactions to the project, particularly excuses made in contacts with agency staff. (Author/DP)
