Lifetime and 12-month prevalence of bipolar spectrum disorder in the National Comorbidity Survey replication.
This study presents the first prevalence estimates of the BPD spectrum in a probability sample of the United States, and finds subthreshold BPD is common, clinically significant, and underdetected in treatment settings. Expand
The long-term natural history of the weekly symptomatic status of bipolar I disorder.
Overall, the symptomatic structure is primarily depressive rather than manic, and subsyndromal and minor affective symptoms predominate, and the longitudinal weekly symptomatic course of BP-I is chronic. Expand
Prevalence and effects of mood disorders on work performance in a nationally representative sample of U.S. workers.
Employer interest in workplace costs of mood disorders should be broadened beyond major depressive disorder to include bipolar disorder, and effectiveness trials are needed to study the return on employer investment of coordinated programs for workplace screening and treatment of bipolar disorder and major depressive Disorder. Expand
The prevalence and disability of bipolar spectrum disorders in the US population: re-analysis of the ECA database taking into account subthreshold cases.
These secondary analyses of the US National ECA database provide convincing evidence for the high prevalence of a spectrum of bipolarity in the community at 6.4%, and indicate that subthreshold cases are at least five times more prevalent than DSM-based core syndromal diagnoses at about 1%. Expand
TEMPS-A: progress towards validation of a self-rated clinical version of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire.
The authors psychometrically validated the TEMPS-A in affectively ill outpatients, leading to an instrument suitable for use in psychiatric, especially affective ill, populations, and conclude that the traits underlying affective disorders are very much part of human nature. Expand
A prospective investigation of the natural history of the long-term weekly symptomatic status of bipolar II disorder.
The longitudinal symptomatic course of BP-II is chronic and is dominated by depressive rather than hypomanic or cycling/mixed symptoms, involving primarily symptoms of minor and subsyndromal severity. Expand
Re-evaluating the prevalence of and diagnostic composition within the broad clinical spectrum of bipolar disorders.
The present review did not consider cyclic, seasonal, irritable-dysphoric or otherwise impulse-ridden, intermittently explosive or agitated psychiatric conditions for which the bipolar connection is less established. Expand
TEMPS-A: validation of a short version of a self-rated instrument designed to measure variations in temperament.
OBJECTIVE To validate a short English-language version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-autoquestionnaire version (TEMPS-A), a self-report questionnaire designed toExpand
Switching from 'unipolar' to bipolar II. An 11-year prospective study of clinical and temperamental predictors in 559 patients.
The profile of patients with MDD who would convert to the more subtle bipolar subtype (known as BPII) on the basis of clinical and personality variables obtained during MDD episodes was associated with early age at onset of MDD and pleomorphic psychopathology beyond the usual affective realm. Expand
A prospective 12-year study of subsyndromal and syndromal depressive symptoms in unipolar major depressive disorders.
The long-term weekly course of unipolar MDD is dominated by prolonged symptomatic chronicity, and MDD, MinD, and SSD symptom levels commonly alternate over time in the same patients as a symptomatic continuum of illness activity of a single clinical disease. Expand
