USING THE GENERAL BEHAVIOR INVENTORY TO SCREEN FOR MOOD DISORDERS AMONG PATIENTS WITH PSYCHOACTIVE SUBSTANCE DEPENDENCE

The General Behavior Inventory (GBI), a self-report instrument that me asures mood disorders, was completed by 224 drug-dependent subjects, w ho also completed other psychometric tests, underwent clinical psychia tric evaluation blind to GBI results, and provided urine toxicology sp ecimens during outpatient treatment. The GBI found unipolar and bipola r disorders in 10.7% and 15.6% of subjects, respectively. Less than op timal concordance occurred between clinical diagnoses and GBI findings . GBI unipolar patients and bipolar patients appeared globally signifi cantly more disturbed than subjects without GBI mood disorders on the Minnesota Multiphasic Personality Inventory-168 and the Million Clinic al Multiaxial Inventory. GBI bipolar patients tended to have greater f requency of cocaine use prior to and during treatment than the other t wo groups. The GBI delineates subgroups of addicts with distinctive ps ychopathology, who in some cases escape clinical detection. Cocaine us e shows an association with GBI bipolar disorders.
