Abstract
ABSTRACT The Dutch Diagnostic Instrument for Mild Aphasia (DIMA-nl) is a standardized battery recently created for evaluating the language performance of patients during the perioperative period of glioma surgery. Our aim was to establish normative data for the DIMA-fr, a French version of the DIMA-nl. The DIMA-nl was first adapted to French. The 14 subtasks of the DIMA-fr were then administered to 391 participants recruited from the general French population. The effects of sex, age and level of education were determined by analysis of variance (ANOVA). Normative data were computed as means, medians, standard deviations and percentiles. Our results demonstrated that age and level of education had an effect on the performance of all subtests but not sex. We thus stratified the norms into four different groups: (i) 18–69 years-old with Baccalauréat (Bac, the French High School Diploma) (n = 246); (ii) 18–69 years-old without Bac (n = 70); (iii) >70 years-old with Bac (n = 48); (iv) >70 years-old without Bac (n = 27). The DIMA-fr is thus the first standardized French battery of tests to specifically assess language during the perioperative period of awake glioma surgery. However, to be used in the clinic, the DIMA-fr must now be validated in patients. The DIMA, which is currently standardized in several languages, could become a reference tool for international studies.
