    Examination of everyday memory in an elderly New Zealand population : improving the utility of the Rivermead Behavioural Memory Test : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Psychology at Massey University
    (Massey University, 1996) Fraser, Sean D
    With the increase in the numbers of elderly in the population and the recent identification of diverse dementias, a need has arisen for improved assessment of memory for this population. The Rivermead Behavioural Memory Test (RBMT) is one of the major tests for working memory and is well suited for use with the elderly. However, normative data for the elderly is limited and the measure has not been assessed for use with a New Zealand population. This study reports RBMT normative data for 138 elderly, non-dementing, community dwelling volunteers in New Zealand, in 3 age specific groups; 60-69, 70-79, 80-89 years. Results showed significant differences (p=0.05) between the data collected in Oxford and New Zealand, with New Zealand results generally higher on most sub-tests. This was considered to be due to a combination of factors including; cultural differences, screening methods for dementia and attention to test anxiety. In addition, a significant difference (p=0.05) was observed on 1 of the sub-tests (Appointment) when comparing test scores across the age groups.

    Measuring memory in older adults : the relevance of everyday memory and the Rivermead Behavioural Memory Test : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Psychology at Massey University
    (Massey University, 1999) Glass, John Notman; Glass, John Notman
    Assessment of memory in older adults is complicated by the varying health and disability status of older individuals, by normal age-related changes and by inadequacies in the theory underpinning memory aging. Additionally, there are limitations in conventional measures of memory when used with older adults particularly in the lack of ecological validity in measuring everyday memory processes. This limitation may risk overestimating the degree of impairment relative to the typical daily demands on memory experienced by older people. The current studies present an evaluation of the Rivermead Behavioural Memory Test (RBMT), a measure of everyday memory performance, which appeared to address some of these concerns. The RBMT was produced as a screening tool, but an exploratory study suggested that some of its subtests may discriminate between dementias of vascular and nonvascular origin. A series of studies were subsequently undertaken to evaluate the properties of the test when used in clinical memory assessment of older adults. Results supported the use of the RBMT as both a screening and diagnostic tool. This expanded use requires clinical norms based on the subtest raw scores. Results also supported the view that everyday memory remains relatively stable into the ninth decade in the absence of a dementing condition. The RBMT was not designed against a theoretical concept or model. Findings from these studies are interpreted within a working memory and systems theory framework. It is concluded that short composite measures relevant to everyday memory experiences might ultimately prove more reliable and valid than conventional tests, in assessing memory in older adults.
