This report concerns parents who contact a mental health agency to obtain help for their children and do not cooperate with agency procedures. Some suggestions are made regarding measures for identifying cooperative and uncooperative parents. These suggestions were based on data collected while cooperation of mothers was being solicited during conduct of a secondary prevention project involving the identification of antisocial kindergarten-age boys. A "normal" control group was included. Number of excuses given by mothers predicted their lack of cooperation with the identification procedures, and cooperation with subsequent ones. (Author/DP)
