BACKGROUND There are obstacles to early identification of bipolar disorder. Identifying and treating illness early in its time course may be associated with a better prognosis. METHODS A questionnaire was administered at interview, when the participant was euthymic, to participants (n=240) enrolled in the Bipolar Comprehensive Outcomes Study (BCOS).(More)
BACKGROUND Previous research has predominately focused on patients with mental illness as the instigators, rather than the victims, of violence and criminal activity. However, patients with schizophrenia appear to experience a higher degree of victimization compared to general community samples. We aimed to establish the 1-month prevalence of violent and(More)
The positive and negative syndrome scale (PANSS) is widely used in psychiatric research. Reflecting this common use, considerable attention has been applied to the psychometric properties of this instrument. However, despite the publication of numerous studies and analyses, it remains uncertain how best data from the PANSS should be analysed to best model(More)
OBJECTIVES The clinical significance of subthreshold mixed states is unclear. This study investigated the clinical outcomes in participants with bipolar I disorder or schizoaffective disorder, using the Cassidy and Benazzi criteria for manic and depressive mixed states, respectively. METHODS Participants (N=239) in a prospective observational study of(More)
OBJECTIVE In some individuals, recovery from episodes of mental illness may be impeded by maladaptive illness beliefs and behaviors. For individuals with chronic illness, acceptance of its presence and consequences is necessary to seek appropriate treatment, adjust their lifestyle, and adhere to recommended management strategies. Some have difficulty(More)
OBJECTIVE The treatment of patients with schizophrenia consumes a considerable proportion of health service budgets, yet there have been few attempts to prospectively analyse the costs associated with this condition. Amid the current debate about where to invest scarce treatment resources to achieve optimal outcomes, real-world studies, such as the(More)
BACKGROUND Tobacco smoking is more prevalent among people with mental illnesses, including bipolar disorder, than in the general community. Most data are cross-sectional, and there are no prospective trials examining the relationship of smoking to outcome in bipolar disorder. The impact of tobacco smoking on mental health outcomes was investigated in a(More)
OBJECTIVE Depressive symptoms are common in schizophrenia but their relationship to the positive and negative symptoms of the disorder and to extrapyramidal side-effects remains unclear. Considerable overlap exists between these symptom clusters when rated with traditional clinical rating scales. The aim of this study was to investigate the relationship of(More)
OBJECTIVES Recent studies have proposed the existence of three distinct subgroups of bipolar 1 disorder based on age at onset (AAO). The present study aims to investigate potential clinical and functional differences between these subgroups in an Australian sample. METHODS Participants (n = 239) were enrolled in the Bipolar Comprehensive Outcomes Study(More)
OBJECTIVE It has been increasingly recognized that there is need to assess patient outcomes in schizophrenia across a broad range of dimensions. But few studies have attempted to do this in clinical populations and no systematic study has broadly assessed outcomes in schizophrenia in Australia using a longitudinal design. Thus, a real-world study, the(More)
