Validity Studies of Scores from a Delinquency-Proneness Scale
The purpose of this study was to investigate two modes of administration (paper and pencil and slide projector) of a delinquency-proneness (D-P) scale in relation to criterion data concerning past and future school and legal difficulties and withdrawal from school. D-P scores were also considered in relation to measures of personal aggression, indolence, and rigidity. Ss were 400 male and female white tenth grade students in three Florida public schools. It was concluded that neither mode was superior to the other in predicting the criterion measures. A statistically non-significant tendency for persons with high aggression and low rigidity to produce higher D-P scores on the projected mode than on the paper and pencil mode was noted. The discrepancy between the magnitude of D-P scores for the two modes increased as the item exposure interval for the projected mode decreased.
