The Tridimensional Personality Questionnaire as a predictor of six-month outcome in first episode mania.
Additional Document Info
The authors administered the Tridimensional Personality Questionnaire (TPQ) near hospital discharge to 27 patients with first episode mania. All patients met DSM-III-R criteria for bipolar disorder, manic type, as assessed by the Structured Clinical Interview for DSM-III-R. Associations of TPQ scores with operationalized outcome variables were analyzed. Outcome variables included syndromic recovery at discharge and at 6 months, syndromic recurrence, and functional recovery. Patients who failed to achieve functional recovery by 6 months had significantly higher Novelty-Seeking dimensional scores at the time of hospital discharge. This association between TPQ scores and short-term outcome suggests that elevated Novelty-Seeking scores may reflect either personality characteristics that impair functional recovery or subclinical manic symptomatology that is not reflected in other symptom measures. The TPQ may provide useful prognostic measures in patients with new onset mania.
