To validate and examine the psychometric properties of the Chinese version of QUALIDEM (QUALIDEM-C).
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.
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.
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.
验证并考察 QUALIDEM 中文版（QUALIDEM-C）的心理测量学特性。
在长期护理院的 150 名居民样本中测试 QUALIDEM-C 的心理测量学特性。确定了同时效度、内部一致性、评分者间信度、重测信度和因子结构。
QUALIDEM-C 与原始版本具有良好的语义等价性和良好的内容效度。QUALIDEM-C 表现出良好的内部一致性（Cronbach's alpha = 0.895）、评分者间信度（ICC = 0.970）和重测信度（ICC = 0.942）。QUALIDEM-C 与通用和特定疾病的生活质量测量指标具有一致的中度相关性，表明具有可接受的同时效度。
QUALIDEM-C 是一种可靠和有效的量表，可用于测量长期护理院居民的生活质量。它在不同认知功能水平的居民中的适用性优于其他在该背景下的测量工具。它是一种有效的工具，而不是通过多种测量方式，用于评估未来长期护理院研究中的生活质量。
