With the rapid growth of the older population, early detection of cognitive deficits is crucial in slowing down functional deterioration of the elderly persons.
To examine the validity and reliability of the Chinese (Cantonese) version of the Hierarchic Dementia Scale (CV-HDS) for Chinese older persons in Hong Kong.
The HDS was translated into Cantonese Chinese. The content and cultural validity were evaluated by six expert panel members. Sixty-two participants with diagnosis of dementia were recruited for evaluation. Inter-rater reliability, test-retest reliability, internal consistency and concurrent validity were examined.
The CV-HDS demonstrated satisfactory psychometric properties. inter-rater reliability and test-retest reliability were high (alpha=0.89 and alpha=0.94 respectively). High value of Cronbach's alpha (alpha=0.94) demonstrated good internal consistency. The concurrent validity of CV-HDS, through correlation with its scores with that of the Chinese version of Mini Mental Status Examination, was established (ranged from r=0.58 to r=0.78, p<0.01).
The CV-HDS is a reliable and valid instrument for assessing severity of cognitive impairment in Cantonese speaking Chinese people with dementia. It facilitates treatment planning to optimize the effects of functional training and rehabilitation.
随着老年人口的迅速增长，认知缺陷的早期检测对于减缓老年人的功能衰退至关重要。
检验香港中文版分层痴呆量表（CV-HDS）对中国老年人的有效性和可靠性。
将HDS翻译成粤语。由六名专家组成的小组评估其内容和文化效度。招募了62名被诊断为痴呆症的参与者进行评估。检验了评分者间信度、重测信度、内部一致性和同时效度。
CV-HDS显示出令人满意的心理测量特性。评分者间信度和重测信度较高（分别为α=0.89和α=0.94）。克朗巴赫α系数（α=0.94）的值较高，表明内部一致性良好。通过将CV-HDS的分数与中文版简易精神状态检查表的分数进行相关性分析，建立了其同时效度（r范围为0.58至0.78，p<0.01）。
CV-HDS是评估说粤语的中国痴呆症患者认知障碍严重程度的可靠且有效的工具。它有助于制定治疗计划，以优化功能训练和康复的效果。
