Scientific justification : Improvement by training has been demonstrated in Schizophrenic patients for various cognitive functions and skills, though not yet for the social cognition ability specifically dedicated to infer others' intention when not explicit.
Main hypothesis : Abilities to infer other's intention can improve in schizophrenic patients following specific practice.
Primary aim : To demonstrate this improvement, as quantified by improvement of V-SIR scores (V-LIS scores in French literature).
Procedure : Ten weekly sessions of a novel cognitive therapy that makes use of videos aimed at learning a better use of contextual information to infer others' intentions. Group of 5 patients trained by 2 therapists. Comparison with a non-cognitive psycho-educational training (same organisational design).
Study design : Controlled randomized simple blind study (equivalent to a Phase IIb therapeutic trial). Matched pair design. 40 patients (20 per arm).
