Reliability between the five forms of the Randt Memory Test and their equivalence

The Randt Memory Test (RMT), a recently developed memory test for longitudinal assessment of mild and/or moderate memory deficits provides five different parallel forms. The aim of this study was to control the reliability between forms and their equivalence. A randomized sequence of these five forms was administered to 20 young, healthy university students, balanced by sex, to exclude possible interference due to large IQ discrepancy and/or different degrees of age-related impairment. An analysis of variance for repeated measures was carried out to evaluate the between form equivalence and the possible sequential effect on repetitions. Reliability between form was also controlled by the Cronbach's alpha. Results show a sufficient high internal consistency and stability of the RMT when used in a repeated measures model, and suggest the need to develop time related curves of the RMT scores for groups of patients with diverse memory disturbances.
