Investigations questioning the ecological validity of standardized neuropsychological instruments have led to the development of tests that are purported to be relevant to everyday functioning. The present investigation examined the relationships of the Rivermead Behavioural Memory Test (RBMT) and the Wechsler Memory Scale-Revised (WMS-R) to estimates of everyday memory functioning, as measured by patient and relative ratings on the Everyday Memory Questionnaire (EMQ). The research participants consisted of a group allegedly exposed to neurotoxicants (n = 29), and a demographically similar comparison group (n = 20). Results indicated that the two objective memory tests did not significantly differ in their relationships to estimates of everyday memory functioning, and that use of the tests together did not improve prediction of memory complaints over the use of one test alone. In addition, patient and relative ratings were highly correlated. These results are discussed within the context of the validity of patient and relative rating scales as estimates of everyday memory impairment.
