The Dutch version of the Oxford Cognitive Screen (OCS-NL): Normative Data and their Association with Age and Socio-economic status

The Oxford Cognitive Screen (OCS) is a screening tool specifically designed for acute stroke patients, assessing 5 domains: attention and executive functions, language, praxis, numeric cognition and memory. Here we present norms for the Dutch version of the OCS (OCS-NL). We evaluated whether age and socio-economic status were linked to OCS-NL performance, since stroke prevalence and recovery are associated to these characteristics. We acquired normative data of the OCS-NL version A in 246 neurologically healthy participants and a subset of 179 participants also completed parallel version B. Socio-economic status was measured using three indicators: education, income and occupation. Data were analyzed in a Bayesian way and we report credible intervals of effect sizes. There were no systematic differences in OCS-NL global performance between low, middle and high income groups, nor between manual and non-manual workers. There were small differences between low and middle and between low and high education groups, and the association of education and OCS-NL performance did not vary across subtests. The association of age and OCS-NL performance varied across subtests. The naming, praxis, verbal memory and executive task had the strongest association with age. These data suggest that normative data for the OCS-NL do not need to be stratified on income and occupation, that age-specific cut-off scores are especially recommended for the naming, praxis, executive function and verbal memory tasks and that education must be considered when interpreting OCS-NL test scores.
