Conducted 2 studies to develop a Self-Control Rating Scale (SCRS) for children. The 33-item SCRS showed high internal consistency (0.98) and test-retest reliability (0.84). In a validational study of 110 normal 3rd-6th graders, the SCRS correlated significantly with latency and error scores from the Matching Familiar Figures Test, the Q score from the Porteus mazes, and behavioral observations. These correlations remained significant when both MA and CA were partialed out. Discriminant validity was demonstrated by a very low and nonsignificant correlation with IQ and MA. An orthogonal factor analysis resulted in 1 major factor, which was labeled Cognitive-Behavioral Self-Control. The relationship of SCRS scores to age, the differences across grade levels, and the differences between boys and girls were also examined. The 2nd study compared 32 children referred for self-control training with 32 nonreferred children matched on age (127.13 and 126.73 mo, respectively), sex, and IQ. Significant differences were found on the SCRS, Matching Familiar Figures Test latencies, and behavioral observations.
