|Condition or disease||Intervention/treatment||Phase|
|Schizophrenia||Behavioral: original cognitive therapy||Phase 2|
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).
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||26 participants|
|Intervention Model:||Single Group Assignment|
|Official Title:||Cognitive Remediation of the Ability to Infer Intention of Others in Schizophrenic Patients - A Controlled, Randomized Trial (Phase IIb)|
|Study Start Date :||July 2008|
|Actual Primary Completion Date :||September 2010|
|Actual Study Completion Date :||September 2010|
|Experimental: original cognitive therapy||
Behavioral: original cognitive therapy
12 weekly sequences of an original cognitive therapy based on videos involving the learning of a better use of contextual information to infer others' intention. Group of 5 patients trained by 2 therapeutics. Comparison with a non-cognitive psychoeducational training (same organisational design).
|No Intervention: no intervention|
- To demonstrate a measurable improvement of Theory of Mind based ability in schizophrenic patients induced by a novel cognitive therapy, as quantified by improvement of V-SIR scores (V-LIS scores in French literature). [ Time Frame: 6 MONTHS ]
- To measure the extension of improvement to other cognitive functions - specific or non specific - and/or to every day life aptitudes [ Time Frame: 6 MONTHS ]
- To evaluate correlations with functional measurements (e.g., magneto-encephalography, cognitive evoked potentials) [transversal study; longitudinal study]. [ Time Frame: 6 MONTHS ]
