Abstract
  • This study examined the clinical utility of the 7 Up 7 Down Inventory (7U7D) in youths (ages 5-18; N = 1737) presenting to outpatient mental health clinics. Caregivers and youths completed the 7U7D and a semi-structured interview to determine psychiatric diagnoses. Caregiver and youth-reported 7U7D scores significantly identified youth mood and bipolar disorders (areas under the curve .56 - .81, ps <.05), with caregiver-report significantly outperforming youth-report. The 7U7D showed strong incremental validity after controlling for youth demographics and clinical characteristics. Cutoff scores were calculated to generate diagnostic likelihood ratios (DiLR) in a two-step fashion to utilize both hypomanic/manic (7U) and depression (7D) dimensions. 7D optimal cut scores yielded DiLRs between 1.55 and 3.26 for a mood disorder diagnosis. 7U Optimal cut scores yielded DiLRs between 1.00 and 2.11 for a BP diagnosis. The 7U7D demonstrates clinical utility for identifying youth mood disorders and BP from other psychiatric diagnoses.
