AB  - BACKGROUND: The Mini Mental State Examination and Montreal Cognitive Assessment 
      are commonly used as short screening batteries for assessing cognitive impairment 
      after stroke. However, aphasia or hemispatial neglect may interfere with the 
      results. For this reason, we developed the Cognitive Assessment scale for Stroke 
      Patients (CASP), which takes these conditions into consideration and previously 
      demonstrated its superiority over these scales in terms of feasibility. 
      OBJECTIVES: Our goal was to verify the psychometric properties of the (original) 
      French version of the CASP. METHODS: We included 201 patients with a recent first 
      hemispheric stroke and 50 controls. Stroke patients were examined 4 times (visit 
      1 [V1] to visit 4 [V4]) in the subacute post-stroke phase. The structural 
      validity of the CASP was studied by principal factorial analysis, convergent 
      validity by comparison with several variables including a comprehensive 
      neuropsychological assessment, divergent validity by comparison with the total 
      score between stroke patients and controls, and sub-scores between right and left 
      stroke. Internal consistency, reproducibility and sensitivity to change were 
      assessed. We propose the Minimal Clinically Important Difference (MCID) value and 
      a pathological threshold as well as a threshold to predict cognitive change 
      between V1 and V4. RESULTS: Of the 201 participants included (63% male; mean [SD] 
      age 63 [13] years), CASP data were available for 199/150/133/93 at V1/V2/V3/V4, 
      respectively. CASP has a one-dimensional structure. The hypotheses of 
      convergent/divergent validities were confirmed. Internal consistency was good and 
      reliability excellent. Responsiveness was small to moderate, but the MCID could 
      still be estimated. We discuss the choice of a pathological threshold and a 
      predictive threshold of V1 over V4. CONCLUSIONS: CASP has good psychometric 
      properties for screening cognitive impairment in the subacute post-stroke phase, 
      which is consistent with its Italian and Korean versions. It can be used for 
      patients with severe motor aphasia or left hemispatial neglect but not in case of 
      severe oral comprehension or visual impairment.
