Abstract:	Negative symptoms are a core dimension of schizophrenia and other psychoses that account for a large degree of the poor functional outcomes related to these disorders. Newer assessment scales for negative symptoms, such as the Clinical Assessment Interview for Negative Symptoms (CAINS), provide evidence for separate dimensions of motivational and pleasure (MAP) and expression (EXP) dimensions. This study was aimed at extending the analysis of the clinical, functional and cognitive correlates of CAINS dimensions in a sample of patients with psychotic disorders (n = 98) and 50 healthy controls. A psychopathological evaluation was conducted by using the Comprehensive Assessment of Symptoms and History (CASH). To assess the extrapyramidal signs, the UKU scale was used. Community functioning was evaluated by means of real-world and functional attainment measures. Additionally, a full neuropsychological test battery was administered. Pearson correlation and hierarchical multiple linear regression analyses were performed to identify the influencing and predictive factors associated with the CAINS dimensions. The MAP and EXP dimensions showed strong associations with the Scale for the Assessment of Negative Symptoms (SANS) items and were not significantly associated with extra-pyramidal or cognitive deficits. The MAP and EXP CAINS dimensions revealed good predictive validity for real-world functioning and functional attainment measures. These findings suggest that the CAINS scale endorses good convergent validity for the assessment of negative symptoms and is very useful in the prediction of psychosocial functioning. In addition, the CAINS dimensions might provide advantages over old assessment scales on disentangling the complex associations between negative symptoms and cognitive impairment.
