Pilot Study of Interpersonal and Social Rhythm Therapy for Subthreshold Bipolar

IPSRT Subjects will receive weekly 45 minute sessions of IPSRT for 20 weeks. IPSRT sessions focus on reducing symptoms by teaching patients to: a) increase regularity of social rhythms and regulate sleep-wake cycles; b) resolve interpersonal problems that contribute to mood symptoms (role dispute, role transition, grief, or interpersonal deficits); and c) recognize and accept the symptoms of subthreshold BP disorder (psychoeducation). Although we train therapists in techniques that are specific to each component, in practice, these strategies are administered flexibly and fluidly, without distinct boundaries between modalities. During the course of a session, therapists move seamlessly among the techniques, according to patients' needs.
