Abstract
The sensitivity and specificity of MCMI-III Scales T (drug dependence) and B (alcohol dependence) were evaluated with patients (N = 164) in an inpatient substance user treatment program. The sensitivity levels of these two scales improved significantly compared to previous research using the MCMI I and MCMI II Scales T and B. which had not achieved sensitivity values above. 50. However, specificity for detecting alcoholism among drug misusers was lower compared to MCMI I and II studies. Results suggest improved diagnostic sensitivity with the MCMI-III in diagnosing substance misuse, but lowered efficiency in ruling out the disorder.
