The Turkish translation study of the Cognitive Reserve Index Questionnaire (CRIq)

Cognitive reserve (CR) is defined as the ability of individuals to use their brain in a flexible way to cope with brain pathologies and find alternative cognitive strategies. The aim of this study was to adapt Cognitive Reserve Index Questionnaire (CRIq) for Turkish population. The CRIq was administered to 178 healthy participants from 18 to 80 years old. The mean score of total CRI was found to be 97.7 indicating a medium level of CR. In line with the mean score, 68.6% of participants (<i>n</i> = 120) were found to have a medium level of CRI. The elderly group showed lowest total CRI as well as CRI-education, CRI-work, and CRI-leisure scores compared to young and middle-aged groups (<i>p</i> &lt; .05, for all scores). This study provided the first translated measure to assess CR in Turkish population.
