[Study of correlations between self-estimation of memory, psychometric test (SM9) and test of memory in daily life]

Assessment of memory performance is now well established. However, the normal form of assessment does not evaluate memory problems encountered during daily activities, a situation relevant to the evaluation of drug effects on memory components. The present study examines the ecological validity of psychometric tests. 49 individuals, from 20 to 89 years old without any identified pathology were included in the study, with the aim of establishing correlations between an autoquestionnaire of memory, a standard memory battery (SM9) and a daily memory video test (DMV). No correlation was found between self-estimation and objective tests or DMV. A strong correlation (r = 0.81) was found between SM9 and DMV. Imaged information and verbal coding appear to be essential parameters of objective tests. These results confirm the ecological validity of the objective psychometric tests and in particular of SM9.
