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.

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.

Prediction of discharge status of persons with brain injury in rehabilitation.

The present study sought to identify the factors as well as what would predict discharge of persons with brain injury. Demographics (age, pre-injury educational level, pre-injury occupational status) and Disability Rating Scale (DRS) scores during admission and upon discharge were used for discharge status prediction. A multiple discriminant analysis (MDA) revealed that the DRS scores at admission and upon discharge were significant predictors that correctly classified 72% of grouped cases.
