Identifying chronic affective disorders in outpatients: validation of the General Behavior Inventory.
The validity of the General Behavior Inventory (GBI) in screening outpatients for chronic unipolar and bipolar affective conditions was evaluated. The GBI was administered to 492 consecutive patients at a university clinic and a community mental health center. Using a stratified random sampling plan, 167 patients were selected and administered blind structured diagnostic interviews. In addition, unipolar depressives were followed up 6 months after the initial evaluation. Overall, the GBI exhibited fair-to-good positive predictive power and good-to-excellent negative predictive power. In addition, GBI scores in the case range were consistently associated with poor outcome at the 6-month follow-up. These findings suggest that the GBI may provide an economical means of screening for chronic unipolar and bipolar affective conditions in outpatient settings.
