Executive functioning in schizophrenia can be reliably and validly assessed with BADS. The diagnosis of impaired executive functioning may be of clinical usefulness as a marker of more illness severity and poorer functional status.

RBANS revealed coherence in identifying cognitive impairment in schizophrenia patients of a different cultural background, and it is shown to be a sensitive, valid and easy-to-perform tool for the neuropsychological assessment of Spanish patients with schizophrenia.

Background/Aims: Cenesthopathy is mainly associated with schizophrenia; however, its neurobiological basis is nowadays unclear. The general objective was to explore clinical correlates of cenesthopathy and subjective cognitive complaints in schizophrenia. Methods: Participants (n = 30) meeting DSM-IV criteria for psychotic disorder were recruited from a psychiatry unit and assessed with: Association for Methodology and Documentation in Psychiatry (AMDP) system, Positive and Negative Syndrome Scale, Frankfurt Complaint Questionnaire (FCQ), and the Bonn Scale for the Assessment of Basic Symptoms (BSABS). For quantitative variables, means and Spearman correlation coefficients were calculated. Linear regression following backward method and principal component analysis with varimax rotation were used. Results: 83.3% of subjects (73.3% male, mean age, 31.5 years) presented any type of cenesthopathy; all types of cenesthetic basic symptoms were found. Cenesthetic basic symptoms significantly correlated with the AMDP category “fear and anancasm,” FCQ total score, and BSABS cognitive thought disturbances. In the regression analysis only 1 predictor, cognitive thought disturbances, entered the model. In the principal component analysis, a main component which accounted for 22.69% of the variance was found. Conclusions: Cenesthopathy, as assessed with the Bonn Scale (BSABS), is mainly associated with cog­nitive abnormalities including disturbances of thought initiative and mental intentionality, of receptive speech, and subjective retardation or pressure of thoughts.

Attention impairment in schizophrenia primarily involves difficulty in focusing attention, mainly related to negative symptoms. By contrast, sustained attention and vigilance seem to be affected only as a secondary consequence of the impairment to focusing attention.
