Abstract

Studies have shown conflicting results as to whether or not increased years of education provide a buffer against cognitive changes associated with normal ageing. Several factors have been shown to affect the likelihood of any given set of data demonstrating the existence of an effect of cognitive reserve, including gender, level of cognitive functioning, and the cognitive function being measured. Here we compare scores on the Modified Mini-Mental State (3MS; Teng & Chui, 1987) for rural and urban older Canadians from the Canadian Study of Health and Aging (CSHA). The original community sample of 10,263 people 65 years of age and over was tested three times at five-year intervals. Mean age at time 1 was 76.5 years (SD = 7.52). Analysis using linear mixed model analysis of variance on 3MS screening scores showed significant main effects for time, education, age, and rural-urban differences with significant interactions for the nonlinear effect for time and both education and the rural-urban difference. More education seemed to have an effect in this large, representative community sample, with those living in small rural communities scoring lower at the first two test occasions.
