The objectives of this study are: (1) establish normative data and (2) study discriminant validity of this tool with a large panel of EF measures.
Methods:
60 clinically stable SZ patients and 60 controls will be administered MET, as well as two measures of executive function: Wisconsin Card Sorting Test - 64, 6 Elements Test. Functional outcome will be assessed through Behavioural Inventory of Executive Functioning (BRIEF-A), ECHELLES LAUSANNOISES D'AUTO-EVALUATION DES DIFFICULTES ET DES BESOINS (ELADEB scale) and Global Assessment of Functioning scale (GAF scale). Clinical measures will be recorded in patients (Positive And Negative Symptoms Scale (PANSS), State Trait Anxiety Inventory - Y (STAI-Y A), Diagnostic Interview for Genetic Studies (DIGS) and Family Interview for Genetic Studies (FIGS)).
Step1: The investigators will first compare patients and controls on all variables of MET and establish normative data.
Step 2: The investigators will then study the discriminant validity of MET. The investigators will compare MET with traditional measures of executive functioning. The investigators will assess the correlation between each executive measure and functional outcome.
