Abstract
Introduction
A common tool used to measure cognitive reserve is the Cognitive Reserve Index questionnaire (CRIq). In the present study, we aimed to adapt and determine the psychometric properties (validity and intra-rater test-retest reliability) of the Hebrew version of the CRIq in a cohort of people with multiple sclerosis (pwMS).
Methods
Fifty pwMS (30 women aged 48.3 (SD=10.2)) completed the CRIq and the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS), which were used for validation. Secondary outcome measures included the evaluation of depression, anxiety, and perceived fatigue. Twenty-five (of the 50) pwMS were randomly selected and participated in the CRIq intra-rater test-retest reproducibility study based on a 7–12-day interval between tests.
Results
The mean CRIq total was 101.8 (S.D.=13.04), which is considered at the medium level. The CRIq section scores were at a similar medium level. According to Pearson's Rho correlation analysis, the CRIq total score and sections of education, work, and leisure were significantly correlated at a medium level (Rho ranging between 0.282 to 0.415) with the SDMT score, a measurement of cognitive information processing speed. The intraclass correlation coefficient (ICC) values of the CRIq total and CRIq sections ranged between 0.942 to 0.998, indicating a strong correlation.
Conclusions
The Hebrew version of the CRIq is a reliable and valid tool for assessing cognitive reserve in pwMS, hence enabling clinicians and researchers to effectively monitor cognitive reserve in this population.
期刊介绍：
Multiple Sclerosis is an area of ever expanding research and escalating publications. Multiple Sclerosis and Related Disorders is a wide ranging international journal supported by key researchers from all neuroscience domains that focus on MS and associated disease of the central nervous system. The primary aim of this new journal is the rapid publication of high quality original research in the field. Important secondary aims will be timely updates and editorials on important scientific and clinical care advances, controversies in the field, and invited opinion articles from current thought leaders on topical issues. One section of the journal will focus on teaching, written to enhance the practice of community and academic neurologists involved in the care of MS patients. Summaries of key articles written for a lay audience will be provided as an on-line resource.
A team of four chief editors is supported by leading section editors who will commission and appraise original and review articles concerning: clinical neurology, neuroimaging, neuropathology, neuroepidemiology, therapeutics, genetics / transcriptomics, experimental models, neuroimmunology, biomarkers, neuropsychology, neurorehabilitation, measurement scales, teaching, neuroethics and lay communication.
