Eighty-eight patients were admitted to the acute ward of a catchment area suffering from the following functional psychoses: schizophrenia (S; n = 41), affective disorder (AD; n = 22), other disorders (OD; n = 25). Follow-up data were obtained for 97%. Ten patients were dead at follow-up, 8 due to suicide. Sixty-five were personally interviewed. While nearly all the patients had only brief periods of rehospitalization, most had used neuroleptics during the follow-up period. Compared to other samples, functioning at follow-up was fairly good for the AD and OD patients, but rather poor for the S patients.
The reorganization in 1981 of a general hospital psychiatric ward in Oslo, Norway, to achieve a more suitable treatment milieu for patients with schizophrenia resulted in a change in patients' perceptions of the ward atmosphere. Reduced group participation and increased individualized support from staff led patients to perceive of the ward as having a low level of anger and aggression and a high level of order and organization. This study examined whether the reorganization was associated with improved treatment outcome.
Psychiatrists retrospectively examined the charts of all patients with a DSM-III-R diagnosis of schizophrenia or schizophreniform disorder who were admitted to the ward the year before and the second year after the reorganization. Multiple regression analyses were used to examine treatment outcomes for both groups. Outcome was measured indirectly by length of stay, level of functioning at discharge, and whether the patient was rehospitalized during the following seven years.
Patients treated after the reorganization had significantly shorter stays with no reductions in either level of functioning at discharge or length of community tenure after discharge. Differences in demographic characteristics, illness history, or psychopharmacological treatment could not account for differences in outcome.
The results supported the hypothesis that the organization and milieu of brief-stay wards influence the short-term outcome of inpatient treatment of patients with schizophrenia.
Sleep problems in bipolar disorder (BD) are common, but reported rates vary from 10% to 80%, depending on definitions, methodologies and management of potential confounding factors. This multicenter study seeks to address these issues and also compares BD cases with Hypersomnia as well as the more commonly investigated Insomnia and No Sleep Problem groups.
A cross-sectional comparison of sleep profiles in 563 BD I and II individuals who participated in a structured assessment of demographic, clinical, illness history and treatment variables.
Over 40% cases met criteria for Insomnia and 29% for Hypersomnia. In univariate analysis, Insomnia was associated with BD II depression whilst Hypersomnia was associated with BD I depression or euthymia. After controlling for confounders and covariates, it was demonstrated that Hypersomnia cases were significantly more likely to be younger, have BD I and be prescribed antidepressants whilst Insomnia cases had longer illness durations and were more likely to be prescribed benzodiazepines and hypnotics.
Whilst Insomnia symptoms are common in BD, Hypersomnia is a significant, frequently underexplored problem. Detailed analyses of large representative clinical samples are critical to extending our knowledge of differences between subgroups defined by sleep profile.
Previous studies of bipolar disorders indicate that childhood abuse and substance abuse are associated with the disorder. Whether both influence the clinical picture, or if one is mediating the association of the other, has not previously been investigated.
A total of 587 patients with bipolar disorders were recruited from Norway and France. A history of childhood abuse was obtained using the Childhood Trauma Questionnaire. Diagnosis and clinical variables, including substance abuse, were based on structured clinical interviews (Structured Clinical Interview for DSM-IV Axis I disorders or French version of the Diagnostic Interview for Genetic Studies).
Cannabis abuse was significantly associated with childhood abuse, specifically emotional and sexual abuse (? 2 = 8.63, p = 0.003 and ? 2 = 7.55, p = 0.006, respectively). Cannabis abuse was significantly associated with earlier onset of the illness (z = -4.17, p
Many studies have shown associations between a history of childhood trauma and more severe or complex clinical features of bipolar disorders (BD), including suicide attempts and earlier illness onset. However, the psychopathological mechanisms underlying these associations are still unknown. Here, we investigated whether affective lability mediates the relationship between childhood trauma and the severe clinical features of BD.
A total of 342 participants with BD were recruited from France and Norway. Diagnosis and clinical characteristics were assessed using the Diagnostic Interview for Genetic Studies (DIGS) or the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I). Affective lability was measured using the short form of the Affective Lability Scale (ALS-SF). A history of childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Mediation analyses were performed using the SPSS process macro.
Using the mediation model and covariation for the lifetime number of major mood episodes, affective lability was found to statistically mediate the relationship between childhood trauma experiences and several clinical variables, including suicide attempts, mixed episodes and anxiety disorders. No significant mediation effects were found for rapid cycling or age at onset.
Our data suggest that affective lability may represent a psychological dimension that mediates the association between childhood traumatic experiences and the risk of a more severe or complex clinical expression of BD.
