Validation of the Performance of the French Version of the Cerebellar Cognitive-Affective Syndrome Scale (CCASS) as a Screening Test for Cerebellar Cognitive-affective Syndrome: a National Multicenter Study
Sponsor: Groupe Hospitalier de la Region de Mulhouse et Sud Alsace
Summary
The primary objective of the study is to assess the performance of the French version of the Cerebellar Cognitive-Affective Syndrome Scale (CCASS) as a screening test for cerebellar cognitive-affective syndrome. The primary endpoint will be the sensitivity of version 1A of the French scale. The result will be considered positive if the patient fails at least one of the scale's subtests. The diagnosis of a cerebellar cognitive-affective syndrome will be made on the basis of a pathological score in the executive, language, visuospatial or psychoaffective domains of the neuropsychological evaluation (gold standard).

Cerebellar Cognitive-Affective Syndrome Scale
The CCASS will be administered by a neuropsychologist starting with version 1A. An alternative version (1B, 1C or 1D) will also be administered. An interval of approximately 30 minutes should be observed between the two administrations. In order to assess the inter-rater reliability of the scale, a second neuropsychologist will be present in the room and will independently evaluate (i.e., blind to his/her colleague's rating) patient's responses. The choice of alternative version (i.e., 1B, 1C, or 1D) will be randomized.
