Effect of caregiving burden on quality of life among family caregivers of severe mental illness patients:A chain-mediated model of family resilience and perceived stress
Objective:To investigate the quality of life of family caregivers of patients with severe mental illness(SMI)and to explore the effect of caregiving burden on the quality of life of SMI family caregivers based on the ABC-X model,and the role of family resilience and perceived stress.Methods:A questionnaire survey was conducted among 272 SMI family caregivers in Wuhan Mental Health Center by convenience sampling method.The basic information questionnaire,Mos 36-item short-form health survey(SF-36),Zairt caregiver burden interview(ZBI),Chinese family resilience assessment scale(C-FRAS),and Chinese version perceived stress scale(CPSS)were used to investigate the subjects.SPSS 23.0 and Mplus 8.3 were used to describe and analyze the data and build a mediating effect model.Results:The average score of family caregivers'quality of life was 54.26±16.94,and the average scores of caregiving burden,family resilience,and perceived stress were 46.85±15.05,146.33±37.23,and 33.40±6.03,respectively(P<0.01).The results of the structural equation model showed that the caregiving burden of SMI family caregivers had a direct effect on the quality of life(β=-0.412,95%CI:-0.565--0.259),and the relationship between them was affected by family resilience(β=-0.098,95%CI:-0.112--0.074)and perceived stress(β=-0.084,95%CI:-0.104--0.061),and the chain mediating effect was statistically significant between family resilience and perceived stress(β=-0.056,95%CI:-0.074--0.030).Conclusion:The quality of life among SMI family caregivers is lower than that of the normal population.Caregiving burden not only directly predicts the quality of life of SMI family caregivers,but also influences the quality of life through the independent mediating effect of family resilience and perceived stress and their chain mediating effect.
