RESUMO
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 treatment and outcomes in bipolar I or schizoaffective disorder, bipolar type, were grouped based on study entry clinical presentation as having pure depression (n=63) if they satisfied DSM-IV-TR criteria for a Major Depressive Episode (MDE), depressive mixed state if they also had at least three concurrent hypomanic symptoms (n=33), or not depressed (n=143) if they did not satisfy the criteria for MDE. Participants were similarly grouped as having pure mania (n=3) if they satisfied DSM-IV criteria for a Manic Episode, manic mixed state if they also had at least two concurrent depressive symptoms (n=33), or not manic (n=203). Clinical data were collected by interview every 3 months over a 24-month period. RESULTS: Measures of quality of life, mental and physical health over the 24-month period were significantly worse for participants who were classified as having mixed states at study entry on most outcome measures compared to participants who were not in an illness episode at study entry. A depressive mixed state was predictive of greater manic symptomatology over the 24 months compared to participants with pure depression. CONCLUSION: In participants with a current episode of mood disorder, the presence of subthreshold symptoms of opposite polarity was associated with poorer clinical outcomes over a 24-month period.

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). Information was collected about the sequential timeline of specific symptoms of mental illness up to when they first received a diagnosis of Bipolar Disorder or Schizoaffective Disorder. RESULTS: Any symptoms of mental illness were first experienced at 17.5 years (median; Inter Quartile Range (IQR) 13.8-24.3; n=216) and mood swings at 18.0 years (IQR 14-25; n=197). Symptoms of depression were experienced at 18.0 years (IQR 14-25; n=197), a full episode of depression at 21.2 years (IQR 17-28.5; n=200), symptoms of mania at 21.0 years (IQR 16.8-29.5; n=212) and a full episode of mania at 24.1 years (IQR 19-30.5; n=205). Medical treatment was sought at 24.0 years (IQR 19-31.5; n=217). Participants received a diagnosis of Bipolar Disorder or Schizoaffective Disorder at 30.0 years (IQR 23-37.3; n=215). Having had a previous diagnosis other than Bipolar Disorder or Schizoaffective Disorder was reported by 120 of 216 participants who answered this question, most commonly unipolar depression (26.6%). Diagnostic delay was greater in individuals with early onset disorder. CONCLUSIONS: Participants typically experience a long sequential course of symptoms, episodes, treatments and diagnosis. The polarity of onset is most commonly depressive, and subthreshold symptoms tend to precede threshold symptoms of both polarities. LIMITATIONS: Data were collected retrospectively.

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 non-violent victimization in a sample of patients with schizophrenia spectrum disorders and to investigate the determinants of victimization. METHOD: Reports of violent and non-violent victimization were recorded in 348 patients in Dandenong, an outer metropolitan suburb of Melbourne, Australia along with the subjective perception of patients as to their degree of protection from being robbed or attacked. Patients reporting victimization were compared with those who did not, across a range of clinical and psychosocial variables. RESULTS: 11.2% of the sample reported being the victim of non-violent crime and 4.3% the victim of violent crime in the 1-month period. 23.2% reported dissatisfaction with their protection against being attacked or robbed. The major determinant of victimization was the lack of any meaningful daily activity. CONCLUSIONS: Patients with schizophrenia spectrum disorders are at increased risk of victimization, both of the violent and non-violent type. Further research is required to understand the pathways through which victimization occurs and to understand whether psychosocial interventions can reduce victimization in this patient population.

OBJECTIVE: We aimed to explore the relationship between objectively rated quality of life and subjective measures of social functioning and life satisfaction. METHOD: Participants of the Schizophrenia Care and Assessment Program (SCAP) study at Dandenong in Australia were included in this analysis. Subjective ratings of several domains of social functioning and life satisfaction were taken from the SCAP instrument and comparisons made with data from the Quality of Life scale rated by research staff as well as several psychopathology measures. RESULTS: Subjectively reported life satisfaction was not related to positive or negative symptoms of schizophrenia but did correlate with depressive symptoms. Quality of Life scale measures correlated with negative symptoms on most domains. There was very limited overlap in domain items between the life satisfaction and quality of life measures. CONCLUSION: Life satisfaction and objectively rated quality of life are not closely related and appear to have different determinants in patients with schizophrenia.
