The primary objective of the study is to test an intervention to reduce health disparities related to bipolar disorder, a vastly more destructive and difficult to treat condition than previously realized. The outcomes of interest include accurate and timely diagnosis, adequacy of prescribed treatment, retention in treatment, suicidality, and a range of treatment benefits including health-related quality of life, employment, treatment satisfaction, medication adherence, utilization of lower levels of intervention (e.g., outpatients versus partial or inpatient care), and reduction of substance use, medical morbidity and mortality. Particular attention has been paid to the collection of service utilization data to track key health care and social services. Costs for medical and psychiatric treatment, medications, inpatient, rehabilitation, and emergency room services are being ascertained for cost assessment, and patients' mood functioning is being tracked to assess the overall effectiveness of the interventions. The study is also using state-of-the-art assessments of phenotypic clinical variables to develop clinically meaningful predictors of treatment response across the age spectrum and across diverse racial groups.
