A longitudinal examination of the moderating effects of symptoms on the relationship between functional competence and real world functional performance in Schizophrenia
Conclusions Residual negative and depressive symptoms are distinct constructs that impede the use of functional skills in the real world. Depressive symptoms are often overlooked in schizophrenia but appear to be an important factor that limits the use of functional ability in real world environments.

The evolution of illness phases in schizophrenia: A non-parametric item response analysis of the Positive and Negative Syndrome Scale
Conclusion Findings confirm differences in symptom presentation and predominance of particular domains in subpopulations of schizophrenia. Identifying symptom domains characteristic of subpopulations may be more useful in assessing efficacy endpoints than total or subscale scores. (Source: Schizophrenia Research: Cognition)

Cognitive functioning among patients with schizophrenia in a Nigerian hospital: a comparison with mood disorder
Conclusion Patients with the negative or mixed schizophrenia syndrome may suffer more cognitive deficit. Poor verbal performance among patients with schizophrenia may be associated with left or mixed handedness, more severe illness and poor functioning. (Source: Schizophrenia Research: Cognition)

Enhanced vulnerability to distraction does not account for working memory capacity reduction in people with schizophrenia
Publication date: September 2014 Source:Schizophrenia Research: Cognition, Volume 1, Issue 3 Author(s): Molly Erickson , Britta Hahn , Carly Leonard , Benjamin Robinson , Steven Luck , James Gold Although working memory impairment has been well-documented among people with schizophrenia (PSZ), the underlying mechanism of this impairment remains unknown. The present study was conducted in a large sample of PSZ and healthy control subjects (HCS) to test the hypothesis that one putative mechanism – vulnerability to distraction from task-irrelevant stimuli – (1) can account for working memory impairment among PSZ...

Supported employment among veterans with serious mental illness: the role of cognition and social cognition on work outcome
Publication date: September 2014 Source:Schizophrenia Research: Cognition, Volume 1, Issue 3 Author(s): L. Felice Reddy , Robert S. Kern Unemployment is a primary functional deficit for the majority of adults with schizophrenia. Research indicates that over two-thirds of adults living in the community with schizophrenia are unemployed. Despite effective programs to assist with job identification and placement, the ability to attain and maintain employment remains a pressing concern. Neurocognitive functioning is widely acknowledged to be a determinant of work outcome; however, effect sizes tend to be in the small to ...

Utility of the UCSD Performance-based Skills Assessment-Brief Japanese version: discriminative ability and relation to neurocognition
Publication date: September 2014 Source:Schizophrenia Research: Cognition, Volume 1, Issue 3 Author(s): Chika Sumiyoshi , Manbu Takaki , Yuko Okahisa , Thomas L. Patterson , Philip D. Harvey , Tomiki Sumiyoshi The UCSD Performance-based Skills Assessment Brief (the UPSA-B) has been widely used for evaluating functional capacity in patients with schizophrenia. The utility of the battery in a wide range of cultural contexts has been of concern among developers. The current study investigated the validity of the Japanese version of the UPSA-B as a measure of functional capacity and as a co-primary for neurocognion. ...

Working memory impairment as an endophenotypic marker of a schizophrenia diathesis
Publication date: September 2014 Source:Schizophrenia Research: Cognition, Volume 1, Issue 3 Author(s): Sohee Park , Diane C. Gooding This review focuses on the viability of working memory impairment as an endophenotypic marker of a schizophrenia diathesis. It begins with an introduction of the construct of working memory. It follows with a consideration of the operational criteria for defining an endophenotype. Research findings regarding the working memory performance of schizophrenia and schizophrenia-spectrum patients, first-degree relatives of schizophrenia patients and healthy controls, are reviewed in terms of...
