Background Factor analytic studies have shown that in schizophrenia patients, disorganization (conceptual disorganization, bizarre behavior) is a separate dimension from other types of positive symptoms such as reality distortion (delusions and hallucinations). Although some studies have found that disorganization is more strongly linked to neurocognitive deficits and poor functional outcomes than reality distortion, the findings are not always consistent. Methods A meta-analysis of 104 studies (combined n = 8,015) was conducted to determine the magnitude of the relationship between neurocognition and disorganization as compared to reality distortion. Additional analyses were conducted to determine whether the strength of these relationships differed depending on the neurocognitive domain under investigation. Results The relationship between reality distortion and neurocognition was weak (r = -.04; p=.03) as compared to the moderate association between disorganization and neurocognition (r = -.23; p <.01). In each of the six neurocognitive domains that were examined, disorganization was more strongly related to neurocognition (r’s range from -.20 to -.26) than to reality distortion (r’s range from .01 to -.12). Conclusions The effect size of the relationship between neurocognition and disorganization was significantly larger than the effect size of the relationship between neurocognition and reality distortion. These results hold across several neurocognitive domains. These findings support a dimensional view of positive symptoms distinguishing disorganization from reality distortion.

Background Although in the early course of schizophrenia relapse prevention is of paramount importance, there is an increasing emphasis on establishing and maintaining sustained periods of symptom remission. Recovery in the early course of illness is also possible, although the rates of recovery are lower than for symptom remission. Symptom remission and recovery rates vary considerably across recent-onset schizophrenia studies because of lack of consistency in treatment interventions and in applying operational outcome criteria. Method Patients who were within two years of their first psychotic episode (N=77) who were treated with continuous antipsychotic medication in conjunction with psychosocial interventions (without targeted work rehabilitation) were assessed during the first outpatient year after hospital discharge. Published operational criteria were used to classify symptom remission and recovery. Results The rate of full symptom remission maintained for 6 months was 36%, while the rate of recovery for 6 months was 10%. When the same criteria were applied for a continuous period of one year, 22% of patients were found to achieve symptom remission but only 1% of patients met recovery criteria. Using multivariate prediction, the WAIS Comprehension score was a significant predictor of 6 months of good functional outcome. Conclusions Although some schizophrenia patients can achieve both symptom remission and recovery in the early course of illness, the overall rate of symptom remission during the first post-hospitalization year is much higher than the rate of recovery. This suggests that interventions targeting work and social functioning are likely necessary to raise the chances of recovery. Cognitive factors can be predictive of good functional outcome even in the early course of schizophrenia.

Hepatitis B and C are public health problems. Psychiatric patients may be at risk of hepatitis B and C exposure due to lifestyle and inadequate health care. We aimed to determine prevalence of hepatitis B and C virus exposure and associated risk factors in acutely hospitalized psychiatric veterans. A total of 234 individuals consecutively admitted to the psychiatric wards at the West Los Angeles Veterans Affairs Hospital were asked to participate. A total of 129 patients consented and were screened for viral hepatitis risk factors, hepatitis B surface antigen, hepatitis B surface and core antibodies, and hepatitis C antibodies. About 31 and 38% of the patients had been exposed to hepatitis B and C viruses, respectively. Several risk factors were associated with exposure. Inpatient psychiatric veterans seem to have increased rates of hepatitis B and C exposure. This highlights the need for prevention of risk behavior in this vulnerable population.
