Abstract

Objectives

To validate and examine the psychometric properties of the Chinese version of QUALIDEM (QUALIDEM-C).

Methods

The psychometric properties of the Chinese QUALIDEM were tested in a sample of 150 residents in long-term care homes. Concurrent validity, internal consistency, inter-rater reliability, test-retest reliability and factor structure were determined.

Results

QUALIDEM-C demonstrated good semantic equivalence with original version and good content validity. QUALIDEM-C showed satisfactory internal consistency (Cronbachs' alpha = 0.895), inter-rater reliability (ICC = 0.970) and test-retest reliability (ICC = 0.942). Acceptable concurrent validity was showed by consistently moderate correlations of QUALIDEM-C with generic and disease specific quality of life measures.

Conclusions

QUALIDEM-C is reliable and valid scales to measure quality of life of residents in long-term care home. Its applicability across residents with different levels of cognitive function favors its use over other measures in this context. It is potentially an effective tool, rather by multiple measures, to evaluate quality of life in future long-term care home research.

针对长期护理院痴呆症患者的生活质量问卷（QUALIDEM-C）中文版的验证。

目的：验证并研究中文版 QUALIDEM（QUALIDEM-C）的心理测量特性：验证并研究中文版 QUALIDEM（QUALIDEM-C）的心理测量学特性：方法：以 150 名长期护理院的居民为样本，测试中文版 QUALIDEM 的心理测量学特性。结果：中文QUALIDEM-C的心理测量学特性在150名长期护理院居民样本中进行了测试，并确定了并发效度、内部一致性、评分者间信度、测试-再测信度和因子结构：结果表明：QUALIDEM-C 与原始版本具有良好的语义等同性和内容效度。QUALIDEM-C 的内部一致性（Cronbachs' alpha = 0.895）、评分者间信度（ICC = 0.970）和测验再测信度（ICC = 0.942）均令人满意。QUALIDEM-C与一般生活质量和特定疾病生活质量测量结果之间的相关性一直处于中等水平，这表明QUALIDEM-C具有可接受的并发效度：QUALIDEM-C是测量长期护理院住户生活质量的可靠而有效的量表。QUALIDEM-C 适用于不同认知功能水平的住户，因此比其他测量方法更适用于这种情况。在未来的长期护理院研究中，它有可能成为一种有效的评估生活质量的工具，而不是使用多种测量方法。

期刊介绍： The rapidly increasing world population of aged people has led to a growing need to focus attention on the problems of mental disorder in late life. The aim of the Journal is to communicate the results of original research in the causes, treatment and care of all forms of mental disorder which affect the elderly. The Journal is of interest to psychiatrists, psychologists, social scientists, nurses and others engaged in therapeutic professions, together with general neurobiological researchers. The Journal provides an international perspective on the important issue of geriatric psychiatry, and contributions are published from countries throughout the world. Topics covered include epidemiology of mental disorders in old age, clinical aetiological research, post-mortem pathological and neurochemical studies, treatment trials and evaluation of geriatric psychiatry services.
