OBJECTIVES: The differential roles of psychotherapy and pharmacotherapy in the management of bipolar (BP) II depression are unknown. As a first step toward exploring this issue, we conducted a pilot study to evaluate the feasibility and acceptability of comparing a BP-specific psychotherapy [Interpersonal and Social Rhythm Therapy (IPSRT)]to quetiapine as treatments for BP-II depression.
METHODS: Unmedicated individuals (n = 25) meeting DSM-IV criteria for BP-II disorder, currently depressed, were randomly assigned to weekly sessions of IPSRT (n = 14) or quetiapine (n = 11), flexibly dosed from 25-300 mg. Participants were assessed with weekly measures of mood and followed for 12 weeks. Treatment preference was queried prior to randomization.
RESULTS: Using mixed effects models, both groups showed significant declines in the 25-item Hamilton Rating Scale for Depression [F(1,21) = 44, p < 0.0001]and Young Mania Rating Scale [F(1,21) = 20, p = 0.0002]scores over time but no group-by-time interactions. Dropout rates were 21% (n = 3) and 27% (n = 3) in the IPSRT and quetiapine groups, respectively. Overallresponse rates (defined as≥50% reduction in depression scores without an increase in mania scores) were 29% (n = 4) in the IPSRT group and 27% (n = 3) in the quetiapine group. Measures of treatment satisfaction were high in both groups. Treatment preference was not associated with outcomes.
CONCLUSIONS: Outcomes in participants with BP-II depression assigned to IPSRT monotherapy or quetiapine did not differ over 12 weeks in this small study. Follow-up trials should examine characteristics that predict differential response to psychotherapy and pharmacotherapy.
