ABSTRACT
Objective:To explore the correlation and characteristics of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Rivermead Behavioural Memory Test-III (RBMT-III) in evaluating memory ability of patients with brain injuries. Methods:From March, 2016 to February, 2018, 62 patients with brain injuries were evaluated with the Chinese version of MMSE, MoCA and RBMT-III. The correlation among them was analyzed. Results:There was positive correlation among the total scores of MMSE, MoCA and RBMT-III (r = 0.682 to 0.786, P < 0.001), as well as the retrospective memory (r = 0.525 to 0.610, P < 0.001) and long-term memory (r = 0.553 to 0.692, P < 0.001). There was positive correlation between RBMT-III and MMSE in short-term memory (r = 0.337, P = 0.007). The prospective memory of RBMT-III positively correlated with retrospective memory of MMSE and MoCA (r = 0.639, r = 0.585, P < 0.001), and the short-term memory of RBMT-III with long-term memory of MMSE and MoCA (r = 0.454, r = 0.534, P < 0.001). Conclusion:MMSE, MoCA and RBMT-III are consistent in evaluating retrospective memory and long-term memory for patients with brain injuries. RBMT-III and MMSE are consistent in evaluating short-term memory for patients with brain injuries. The memory scores of MMSE and MoCA are helpful to judge the event-based prospective memory in patients with brain injuries, while the scores of long-term memory are helpful to judge short-term memory.
ABSTRACT
Objective To analyze the reliability and validity of the Chinese version of the Rivermead Behavioural Memory Test-Third Edition (RBMT-III). Methods The items of RBMT-III were translated in Chinese and adjusted. A total of 131 healthy subjects were tested with Chinese version of RBMT-III, 30 of them were tested again with other materials two weeks later. Results The Cronbach'sαcoefficient was 0.799. The correlation coefficient of parallel-forms in subtest scale and meory index were all more than 0.65. There were six main fac-tors extracted, which explained 64.47%of the accumulated variance, those were novel task learning, spatial memory, verbal memory, visual memory, prospective memory and orientation/date. Conclusion RBMT-III is a reliable and validated instrument for assessment of memory.
ABSTRACT
Objective To study the utility of sleep intervention combined with memory training for alleviating dysmnesia in the elderly and provide a basis for improving memory function. Methods A total of 647 community-dwelling elderly people were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the Rivermead behavioral memory test ( RBMT). One hundred and fifty elderly persons with sleep disorders and dysmnesia were divided into three groups; the control group, the memory intervention group, and the sleep plus memory training group. Sleep quality and dysmnesia were evaluated again after 3 months of intervention. Results Among the 647 elderly people, the incidence of sleep disorders was 38. 8% , and of dysmnesia was 78. 4%. Dysmnesia was significantly more prevalent among subjects who also had sleep disorders. After three months of intervention, instant recall scores had declined in the control group while scores on 7 kinds of memory function had improved significantly in the memory intervention group. Scores on 10 measures of memory and sleep quality improved in the sleep plus memory intervention group. Compared to the control group, scores on 9 kinds of memory improved significantly in the memory intervention group and scores on 11 kinds of memory improved in the sleep plus memory intervention group. Compared to the memory intervention group, scores on 5 kinds of memory had improved significantly in the sleep plus memory intervention group. Conclusions The occurrence of dysmnesia in elderly people is influenced by sleep quality. Memory training can improve their memory function, but sleep intervention combined with memory training is even more effective.
ABSTRACT
@#The authors introduce the items,scores,reliability,validity,the differences between the Rivermead Behavioural Memory Test Second Edition(RBMT-Ⅱ) and RBMT-Ⅰand characteristics of the RBMT-Ⅱ(2003).RBMT-Ⅱ is more practicable in clinical than general standard memory tests,it is good for clinical rehabilitation.
