More validated instruments for assessment of behavioral and psychological symptoms of dementia are required to facilitate local dementia research.
The psychometric properties of the Chinese version of the neuropsychiatric inventory (CNPI) were tested in a sample of 62 dementia outpatients. The concurrent validity was tested by measuring the Spearman correlation between CNPI subscales with the appropriate subscales of BEHAVE-AD and the Chinese Hamilton rating scale of depression (CHDS). The internal consistency reliability, false-negative rates of the screening questions of CNPI and inter-rater reliability were determined.
Most CNPI behavioral domains achieved significant correlation with the corresponding BEHAVE-AD and CHDS subscales. Cronbach alpha for the overall reliability was 0.84. The false-negative rates of the screening question were acceptable except for the dysphoria, sleep and appetite domains. The inter-rater reliability was satisfactory with intraclass correlation coefficient of all subscales above 0.9.
The study demonstrated the applicability of the CNPI in assessing the neuropsychiatric manifestations of dementia in the Chinese community.
需要更多经过验证的工具来评估痴呆的行为和心理症状，以促进当地的痴呆症研究。
对62名痴呆门诊患者样本测试了中文版神经精神问卷（CNPI）的心理测量特性。通过测量CNPI分量表与BEHAVE-AD相应分量表以及中国汉密尔顿抑郁量表（CHDS）之间的斯皮尔曼相关性来测试同时效度。确定了内部一致性信度、CNPI筛查问题的假阴性率和评分者间信度。
大多数CNPI行为领域与相应的BEHAVE-AD和CHDS分量表具有显著相关性。总体信度的Cronbach α为0.84。除烦躁不安、睡眠和食欲领域外，筛查问题的假阴性率是可以接受的。评分者间信度令人满意，所有分量表的组内相关系数均高于0.9。
该研究证明了CNPI在评估中国社区痴呆症神经精神表现方面的适用性。
