Impact of caregiver burden on caregiver mental health in patients with esophageal cancer: chain mediating effects of benefit finding and rumination, a cross-sectional study

BACKGROUND: Cancer caregivers are the main supporter for the tumor patients, they not only need to provide daily nursing to the patients, but also suffering the pressure from economy, emotion and even family members. The mental health of tumor patient is mostly noticed, while not caregivers. The mental health of caregiver greatly affected the nursing quality and even the treatment outcomes. In the current study, the mechanisms underlying the links between caregiver burden, benefit finding, mental health, and rumination in those caring for people with esophageal cancer were examined. METHODS: The study was using a convenience sampling, 166 esophageal cancer patients in 2 general hospitals in Jiangsu Province, China, and caregivers of patients were included after excluded the non-conforming patients. Data were collected using investigator-developed questionnaires, the Benefit Finding Scale (BFS), the Event-Related Rumination Inventory (ERRI), the Zarit Burden Interview (ZBI), and the Hospital Anxiety and Depression Scale (HADS) during May 2020 to December 2020. The results were analyzed by SPSS, and the chain mediating effect was analyzed by the the SPSS PROCESS Macro Model. RESULTS: The study comprised 166 caregivers with an average age of (59.96±11.48) years, most of them were female (85.5%). The ZBI was positive correlated with HADS (r=0.882, P<0.01), and negative correlated with BFS (r=−0.873, P<0.01). Intrusive rumination and deliberate rumination in caregivers were negatively correlated (r=−0.901, P<0.01) and positive correlated (r=0.904, P<0.01) with BFS scores, respectively. Furthermore, research have discovered a chain mediation impact of benefit finding and rumination between caregiver burden and psychological well-being among carers of esophageal cancer patients. CONCLUSIONS: The findings of this study imply that benefit finding and rumination are crucial components of the coping strategy used to buffer against negative emotion (such as anxiety and depression). Therefore, the mental health of caregivers should also be noticed, and health care professionals should provide targeted interventions to increase the caregiver’s level of benefit finding and promote deliberate ruminative thinking.
