    (Elsevier, 2022) Heo, Seongkum; Lennie, Terry A.; Moser, Debra K.; Dunbar, Sandra B.; Pressler, Susan J.; Kim, JinShil; School of Nursing
    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.
