The EVACO Project: A new battery for assessing social cognition disorders and related psychiatric disability in schizophrenia

The relation of social cognitive disorders and schizophrenic symptoms are well-established. Yet, assessment methods have not reached a consensus. In addition, causal paths between neurocognition, social cognition, symptoms and functional expression are not clearly understood. During the past few years, some authoritative accounts proposed specialized batteries of tests and emphasized theory of mind, emotion recognition, and interpretation bias constructs: – NIMH's “Social cognition psychometric evaluation” battery (Pinkham AE, Penn DL, Green MF, Harvey PD. Schizophrenia Bulletin , 2015); – “Social cognition and functioning in schizophrenia” (Green MF, Lee J, Ochsner KN. Schizophrenia Bulletin , 2013). Interestingly, these accounts stemming either from expert consensus and psychometric considerations or from neuroscience knowledge recognized some difficulties in providing a fully usable set of instruments. The project described here (EVACO protocol, funded by the Programme Hospitalier de Recherche Clinique national) follows an alternative approach and aims at providing a psychometrically validated battery. Based on a cognitive neuropsychology view on schizophrenic functional disability, several tests were gathered and are assessed in a 12-months multi-center follow-up of 160 individuals with schizophrenia. The FondaMental foundation network of Expert Centers is involved in recruiting patients from eight centers (Clermont-Ferrand, Colombes, Creteil, Grenoble, Marseille, Montpellier, Strasbourg, Versailles). To-date, the first evaluation of the population has been achieved. Experience reports and inclusions follow-up demonstrate the good acceptability of this battery both on the patients and the evaluator's side. We emphasize the usefulness of this project to meet the clinicians’ needs of validated social cognition tools, by describing different scenarios of use.
