Social-cognitive Functioning: Validation of a New Neuropsychological Test

Condition(s) studied

Investigational drug(s) / intervention(s)

REALSOCOG: Patients will be asked to perform the REALSoCog serious game-type social cognition assessment task developed by the LMC2 laboratory (UR 7536). Their performance will be compared to those of control individuals recruited in parallel (independant clinical study: CER-U, IRB N°: 00012020-115). Participants will be asked to think about 16 social situations (6 control situations and 10 experimental situations) encountered in a virtual environment representing a city. REALSoCog can be used on a laptop computer, without any additional technical device.

BCS: Social-cognitive tasks from the BCS (Ehrlé et al., 2011) will also be offered to patients to test the concurrent validity of REALSoCog. This battery assesses social cognition. It includes paper-and-pencil tasks.

Hetero-questionnaires: Hetero-questionnaires assessing patients' social behavior will be transmitted to their relative or primary caregiver (Godefroy \& le GREFEX, 2008; Gury and Ehrlé, in progress of validation) in order to verify the concurrent validity of REALSoCog. These hetero-questionnaires aim to identify and quantify the presence of social skills and behaviour disorders.

Study summary

It is now established that disturbances in social cognition are frequent in neurology and that they contribute to the development of social conduct disorders. Their assessment is therefore essential, particularly in order to propose early and adapted care. However, this assessment remains limited today. A new serious game-type test, REALSoCog, has been developed to address the shortcomings of current tools and to highlight disturbances in social behaviors. The latter are not always observed in consultation although they are often reported by caregivers. The objective of this research is therefore to validate the REALSoCog task in a pathological population (currently being standardized in the general population: CER-U, IRB N°: 00012020-115). The clinical interest of this task will be tested with a group of patients suffering from a neurodegenerative disease (Alzheimer's disease (AD), dementia with Lewy bodies (DCL), fronto-temporal lobar degeneration (FTD)) in order to assess its sensitivity and specificity in the detection of social-cognitive disturbances, and in particular in terms of social behaviors (detection of social behavioral disorders reported in daily life). The objective is also to document the socio-cognitive profiles in the mentioned diseases thanks to a more ecological test, and to better understand the links between socio-cognitive processes on the one hand, and individual characteristics on the other hand (e.g. mood and social participation).

Eligibility

Primary outcome measure(s)

• rate of inappropriate behavioural intentions — 1 hour and a half
  It is measured by the REALSoCog task through a question asking the participant to specify his behavioral intention in the case where he would have declared his intention to act in front of the social situation presented. These questions are asked for each social situation presented, i.e. for a total of 16 situations
