Alternative cut-point scores for the CAST-6.

Alternative cut-point scores for the CAST-6, a shortened version of the Children of Alcoholics Screening Test, are examined in three samples: outpatient substance abusers, outpatient psychiatric patients, and medical students. Hit rates for identification are maximized with a lower cut-point for medical students and a higher cut-point for a sample of individuals seeking outpatient treatment for substance abuse. Either cut-point yields equivalent results in an outpatient psychiatric sample.
