The mediating role of loneliness between psychological resilience and health-related quality of life among patients with nasopharyngeal carcinoma: a cross-sectional study using structural equation modeling
Abstract
Abstract Background Cancer patients’ health-related quality of life (HRQoL) has always been a hot discussion spot. Loneliness and psychological resilience are considered to be significant psychosocial factors impacting the HRQoL of the cancer population. However, there is a lack of studies on the interrelationship among loneliness, resilience, and HRQoL in patients with nasopharyngeal carcinoma (NPC). This study aims to explore the relationship between resilience and HRQoL among NPC patients and to recognize the potential mediating role of loneliness in this relationship. Methods A cross-sectional study was performed in this study. A convenience sampling method was conducted to recruit participants. A total of 155 patients with nasopharyngeal carcinoma were required to complete the socio-demographic questionnaire, the Cancer Loneliness Scale (CLS), the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), and the European Organization for Research and Treatment of Quality of Life Questionnaire C-30 (EORTC QLQ-C30) from April 2022 to August 2022 in a tertiary grade A hospital in Guangzhou, China. The multiple linear regression analysis was used to identify influencing factors, and structural equation modeling with the bootstrap method was performed to test the mediating role of loneliness. This study complied with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Results HRQoL was at a median level among NPC patients, with a mean score of 64.19 (24.38) on the Global health status/quality of life (GHS/QoL) scale. Monthly household income (B = 4.973, P < 0.001), cancer stage (B=-4.342, P = 0.004), psychological resilience (B = 0.914, P < 0.001), and loneliness (B =-1.083, P < 0.001) were independent factors related to HRQoL, explaining 36.7% of the variance of HRQoL. Psychological resilience exerted its direct negative impact on loneliness (β = -0.199, BC95%CI = -0.318/-0.089), and it also had a both direct and indirect positive impact on HRQoL (β = 0.653, BC95%CI = 0.423/0.912; β = 0.142, BC95%CI = 0.046/0.296). Loneliness exerted a partially mediating impact on the relationship between psychological resilience and HRQoL. Conclusions NPC patients with higher monthly household, early stages of cancer, higher resilience, and lower loneliness show a better HRQoL. Resilience has an indirect positive impact on HRQoL by influencing loneliness in NPC patients. It is suggested that healthcare staff should strive to enhancing resilience and reducing loneliness as new strategies to promote NPC patients’ HRQoL further.
