Psychological symptoms, physical symptoms, and behavioral factors can affect health-related quality of life (HRQOL) through different pathways, but the relationships have not been fully tested in prior theoretical models. The purpose of this study was to examine direct and indirect relationships of demographic (age), biological/physiological (comorbidity), psychological (depressive symptoms), social (social support), physical (physical symptoms and functional status), and behavioral (dietary sodium adherence) factors to HRQOL. Data from 358 patients with heart failure were analyzed using structural equation modeling. There was a good model fit: Chi-square = 5.488, p = .241, RMSEA = .032, CFI = .998, TLI = .985, and SRMR = .018. Psychological symptoms, physical symptoms, and demographic factors were directly and indirectly associated, while behavioral and biological/physiological factors were indirectly associated with HRQOL through different pathways. Behavioral factors need to be included, and psychological factors and physical factors need to be separated in theoretical models of HRQOL.
心理症状、生理症状和行为因素可以通过不同途径影响健康相关生活质量（HRQOL），但这些关系在之前的理论模型中尚未得到充分验证。本研究旨在检验人口统计学（年龄）、生物学/生理学（合并症）、心理学（抑郁症状）、社会（社会支持）、身体（生理症状和功能状态）和行为（饮食钠依从性）因素与 HRQOL 的直接和间接关系。使用结构方程模型对 358 例心力衰竭患者的数据进行了分析。模型拟合良好：卡方值= 5.488，p 值= 0.241，RMSEA= 0.032，CFI= 0.998，TLI= 0.985，SRMR= 0.018。心理症状、生理症状和人口统计学因素直接和间接相关，而行为和生物学/生理学因素通过不同途径与 HRQOL 间接相关。理论模型中需要纳入行为因素，并将心理因素和生理因素分开。
