The RBMT-3 was developed with the goal of updating the clinical applicability and utility of the tool. A number of changes were made to achieve this, such as:
- A larger normative sample has been collected than previous versions of the test.
- It was thought by the authors that some of the subtests in the currently used versions can prove to be a little too difficult (RBMT-E) or a little too easy (RBMT) for certain patients. The RBMT-3 sought to make adjustments in item difficulty to meet this need.
- On the Face Recognition subtests of the original RBMT the ethnic diversity of the local population was not adequately represented. Therefore, the new version includes more pictures of people of African-Caribbean and Asian origin to ensure the test is appropriate for a multi-racial society such as the United Kingdom and the United States of America.
- The stories used to assess a person’s ability to absorb verbal information have also been updated.
- A new subtest – the Novel Task has been added. This novel task assesses the ability of a person to learn a new skill, an accomplishment critical for everyday functioning.
- An intervention chapter has been added to improve the clinical utility of the tool.
- Finally, given that the RBMT-E was published in 1999, a revision of the normative data is required. We stay close to the original structure of the RBMT as this has proved both valid and sensitive to everyday memory problems in people with brain injury. It is hoped that this new version of the RBMT will enhance its function as both a clinical and a research tool.
The history behind the Rivermead Behavioural Memory Test
The Rivermead Behavioural Memory Test (RBMT) was orgionally designed to (a) predict everyday memory problems in people with acquired, non-progressive brain injury and (b) monitor change over time.
The RBMT comprises tasks analogous to everyday situations that appear to be troublesome for memory impaired patients. Numerous studies since the publication of the RBMT have shown the clinical utility of this tool for different patient populations.
In 1999 the Rivermead Behavioural Memory Test – Extended Version (RBMT-E) was published. This version was developed to create an instrument that could detect mild memory deficits. In order to enhance the test’s sensitivity the level of difficulty of the test was increased by doubling the amount of material to be remembered.
Although the RBMT and the RBMT-E proved useful in the assessment of memory, some changes were required to increase the clinical effectiveness of these tests.
In 2003 the RBMT-II was published. This was an update of materials but did not include further development of subtest items or restandardisation of the test.
