To determine the direct and indirect relationships of cognitive, functional, and behavioral factors and other medical comorbidities with the quality of life (QoL) of patients with Alzheimer's disease (AD) according to the theoretical model of dependence.
Observational and cross-sectional study. Cognitive and functional status, behavior, dependence, medical comorbidities, and QoL were assessed by using standardized instruments. A path analysis was used to model the direct and indirect relationships among clinical indicators according to the theoretically based model of dependence.
The sample consisted of 343 patients with AD (32.1% mild, 36.7% moderate, and 31.2% severe). Medical comorbidities, disease severity, and dependence level had a direct relationship with QoL. The functional disability and the behavior disturbances were indirectly related to QoL via dependence level, and the cognitive impairment was indirectly related to QoL via severity level.
Direct and indirect effects exist between clinical indicators, dependence, and QoL.
根据依赖理论模型,确定认知、功能和行为因素以及其他医学合并症与阿尔茨海默病(AD)患者生活质量(QoL)之间的直接和间接关系。
观察性横断面研究。使用标准化工具评估认知和功能状态、行为、依赖程度、医学合并症和生活质量。根据基于理论的依赖模型,采用路径分析对临床指标之间的直接和间接关系进行建模。
样本包括343例AD患者(轻度32.1%,中度36.7%,重度31.2%)。医学合并症、疾病严重程度和依赖程度与生活质量有直接关系。功能残疾和行为障碍通过依赖程度与生活质量间接相关,认知障碍通过严重程度与生活质量间接相关。
临床指标、依赖程度和生活质量之间存在直接和间接影响。
