title: The clinical utility, reliability and validity of the Rivermead Behavioural Memory Test-Third Edition (RBMT-3) in Hong Kong older adults with or without cognitive impairments.
abstract: This study examined the use of the Hong Kong version of the Rivermead Behavioral Memory Test-Third Edition (RBMT-3) for older adults, and by presenting the optimal cut-off scores for patients with cognitive impairments, and for a group of peers who have functional everyday cognition. Hundred older adults residing in community dwellings were recruited from three non-government organisations and completed the RBMT-3: 29 patients with mild to moderate dementia, 34 persons at risk for MCI, and 37 matched older adults with everyday functional cognition for a healthy control group (NC). The test has excellent inter-rater (ICC [2, 1] = 0.997), intra-rater (ICC [3, 1] = 0), and parallel version (ICC [3, 1] = 0.990) reliabilities, as well as satisfactory internal consistency (Cronbach's alpha: 0.643-0.832). The scores of the MCI group were significantly lower than those of NC group in four subtests. The optimal cut-off scaled scores of ≤ 41.5, ≤ 102.5, and ≤ 131.5 are suggested for the RBMT-3 to discriminate between patients with mild and moderate dementia, mild dementia and MCI, and MCI and NC, with sensitivities 73%, 100% and 94.1%, respectively. This version is useful to differentiate those with or without risk of cognitive impairments.
