Used regression equations to determine the predictive power of the abbreviated MacAndrew Scale of the MMPI-168 on self-reported delinquent behavior of 1,672 suburban high school students. The abbreviated MacAndrew Scale score successfully predicted alcohol abuse, but was also shown to be related to crimes against property and persons and to marijuana usage. It was concluded that the MacAndrew Alcoholism Scale may not be uniquely sensitive to alcohol abuse among the population sampled.
