AimSymptoms of bipolar disorder (BD) include changes in mood, activity, energy, sleep, and appetite. Since many of these processes are regulated by circadian function, circadian rhythm disturbance has been examined as a biological feature underlying BD. The International Society for Bipolar Disorders Chronobiology Task Force (CTF) was commissioned to review evidence for neurobiological and behavioral mechanisms pertinent to BD.MethodDrawing upon expertise in animal models, biomarkers, physiology, and behavior, CTF analyzed the relevant cross-disciplinary literature to precisely frame the discussion around circadian rhythm disruption in BD, highlight key findings, and for the first time integrate findings across levels of analysis to develop an internally consistent, coherent theoretical framework.ResultsEvidence from multiple sources implicates the circadian system in mood regulation, with corresponding associations with BD diagnoses and mood-related traits reported across genetic, cellular, physiological, and behavioral domains. However, circadian disruption does not appear to be specific to BD and is present across a variety of high-risk, prodromal, and syndromic psychiatric disorders. Substantial variability and ambiguity among the definitions, concepts and assumptions underlying the research have limited replication and the emergence of consensus findings.ConclusionsFuture research in circadian rhythms and its role in BD is warranted. Well-powered studies that carefully define associations between BD-related and chronobiologically-related constructs, and integrate across levels of analysis will be most illuminating.

Women disadvantaged by poverty, as well as racial or ethnic minority status, are more likely to experience depression than the rest of the U.S. population. At the same time, they are less likely to seek or remain in treatment for depression in traditional mental health settings. This article explores a therapeutic, psychosocial engagement strategy developed to address the barriers to treatment engagement and the application of this strategy to a special population--women of color and white women who are depressed and living on low incomes. The conceptual foundations of this intervention--ethnographic and motivational interviewing--as well as its key techniques and structure are reviewed. Finally, a case example description and promising pilot data demonstrate the usefulness of this strategy.

Objective: To minimize barriers to care, ameliorate antenatal depression, and prevent postpartum depression, we conducted a pilot study to assess the feasibility of providing brief interpersonal psychotherapy (IPT-B) to depressed, pregnant patients on low incomes in an obstetrics and gynecological (OB/GYN) clinic. Method: Twelve pregnant, depressed women were recruited as a convenience sample from the clinic and were offered a pretreatment engagement interview and eight sessions of IPT-B, followed by monthly maintenance IPT sessions up to 6-months postpartum. Results: Nine of these 12 patients (75%) completed eight sessions of IPT-B. Paired t tests showed that completers of IPT-B displayed significant improvement at posttreatment and 6-months postpartum on three measures of depression, a measure of anxiety, and some aspects of social functioning. Conclusions: These preliminary results suggest that providing depression screening and treatment to this sample in an OB/GYN clinic was feasible and accompanied by high rates of clinical and functional improvement.
