The aim of this study was to determine whether the 3R mental stimulation programme can improve the mental status score (MSS) of a group of patients with dementia attending a day care centre. Fifteen patients with dementia attending a day care centre were exposed to the 3R stimulation programme over eight weeks while 15 controls were not. All patients from both groups were subjected to pre- and post-exposure questionnaires modified from the Mental Status Questionnaire of Kahn et al. A mental status score (MSS) was thus calculated on both occasions. All patients in the exposed group showed an improved mental status score, with the mean 'pre-exposure' and 'post-exposure' scores of 4.4 and 7.3, respectively (p < 0.001; paired t test). In contrast, the mental status scores of 12 control patients had deteriorated and mean 'pre-exposure' and 'post-exposure' scores were 4.1 and 3.4, respectively (p < 0.05; paired t test). Using multiple covariance analysis, the adjusted 'post-exposure' mean mental status score was 7.1 for the exposed and 3.6 for the controlled group (p < 0.001). The 3R programme appears to be effective for short-term mental stimulation of demented elderly people.
本研究的目的是确定3R心理刺激方案是否能提高一组在日间护理中心接受治疗的痴呆患者的心理状态评分（MSS）。15名在日间护理中心接受治疗的痴呆患者在八周内接受了3R刺激方案，而15名对照组患者未接受该方案。两组的所有患者都接受了根据Kahn等人的心理状态问卷修改的暴露前后问卷调查。因此，在两个时间点都计算了心理状态评分（MSS）。暴露组的所有患者心理状态评分均有所提高，“暴露前”和“暴露后”的平均评分分别为4.4和7.3（p<0.001；配对t检验）。相比之下，12名对照患者的心理状态评分恶化，“暴露前”和“暴露后”的平均评分分别为4.1和3.4（p<0.05；配对t检验）。使用多元协方差分析，暴露组调整后的“暴露后”平均心理状态评分为7.1，对照组为3.6（p<0.001）。3R方案似乎对痴呆老年人的短期心理刺激有效。
