This proposed study is designed to compare the efficacy of interpersonal and social rhythm therapy (IPSRT) alone to IPSRT plus medication as an acute treatment for bipolar II depression. The investigators propose to conduct a randomized, controlled, trial comparing the effects of IPSRT plus pill placebo to IPSRT plus quetiapine on depressive symptoms in individuals suffering from Bipolar II depression. The investigators will also examine the impact of treatment on psychosocial function.
Specifically, we will enroll 160 individuals meeting DSM-IV criteria for BP II disorder, currently depressed, and randomly assign them to 20 weeks of treatment with IPSRT plus placebo (IPSRT-PLA) (N=80) or IPSRT plus quetiapine (IPSRT-QUE) (N=80). We will evaluate potential moderators of response to treatment including circadian phase preference, intercurrent hypomanic symptoms during the index depressive episode, clinical and demographic factors (i.e, number of previous episodes, family history of mood disorders), and prior treatment response to antidepressant medications.
