Assessing cognitive-related disability in schizophrenia: Reliability, validity and underlying factors of the evaluation of cognitive processes involved in disability in schizophrenia scale.

Purpose: We have developed a new scale that assesses disability caused by cognitive impairments in schizophrenia, in order to evaluate the functional impact of schizophrenia and help the prescription of rehabilitation interventions. The aim of the study was to assess its psychometrical properties.

Materials And Methods: Mental healthcare professionals and relatives of individuals with schizophrenia developed and rated the evaluation of cognitive processes involved in disability in schizophrenia scale, which included 13 items.

Behavioral and brain measures (N400) of semantic priming in patients with schizophrenia: test-retest effect in a longitudinal study.

Aim: The purpose of this study was to investigate whether deficits in the behavioral and/or N400 semantic priming (SP) effect observed in patients with schizophrenia constitute a stable cognitive feature of the disorder or whether they may be influenced by the severity of each individual's symptomatology.

Methods: A 1-year test-retest study was conducted on 15 patients with schizophrenia and 10 healthy participants who performed an SP task. Both behavioral measures and event-related potentials measures of SP were recorded twice (test and retest sessions).

Correlations of theory of mind deficits with clinical patterns and quality of life in schizophrenia.

Background: Numerous studies have demonstrated the existence of theory of mind (ToM) impairments in patients with schizophrenia. The clinical consequences of these impairments are currently under debate. Accumulated evidence suggests that ToM deficits are linked to negative and disorganization symptoms, but direct correlations are lacking.

In patients with schizophrenia, symptoms improvement can be uncorrelated with quality of life improvement.

Objectives: Quality of life has been found to be associated with symptoms in patients with schizophrenia. Nevertheless, the mechanism that underlies this association is still unclear. The objective of this paper is to prospectively evaluate the quality of life of patients with schizophrenia in relation to the concurrent evolution of their symptoms, their expectations and their perceived position in life.
