心力衰竭患者家属照顾者希望水平在疾病不确定感和照顾者准备度间的中介作用

Mediating effect of caregiver hope level of family members of patients with heart failure on disease uncertainty and caregiver readiness

目的探讨心力衰竭患者家属照顾者希望水平在疾病不确定感和照顾者准备度间的中介作用。方法2020年7月至12月,采用方便抽样选取南华大学附属第二医院、南华大学附属南华医院和衡阳市中心医院心血管内科323例心力衰竭患者家属照顾者为研究对象。采用一般情况调查表、疾病不确定感家属量表、Herth希望量表及照顾者准备度量表进行调查,并分析疾病不确定感、希望水平、照顾者准备度间的相关性及中介作用。结果心力衰竭患者家属照顾者疾病不确定感得分为(86.07±10.35)分,希望水平得分为(35.13±4.01)分,照顾者准备度得分为(21.45±5.09)分。相关性分析显示,照顾者准备度与疾病不确定感呈负相关(r=-0.480,P<0.01);照顾者准备度与希望水平呈正相关(r=0.419,P<0.01);疾病不确定感与希望水平呈负相关(r=-0.433,P<0.01)。Bootstrap法验证了希望水平在疾病不确定感和照顾者准备度间的中介效应(β=-0.055,P<0.01),中介效应占总效应的23.31%。结论心力衰竭患者家属照顾者希望水平在疾病不确定感和照顾者准备度间起部分中介作用。

Objective To explore the mediating role of caregiver hope level of family members of patients with heart failure on disease uncertainty and caregiver readiness.Methods From July to December 2020,a total of 323 family caregivers of patients with heart failure in the Department of Cardiovascular Medicine of the Second Affiliated Hospital of South China University,South China Hospital Affiliated to South China University,and Hengyang Central Hospital were selected as the research objects by convenience sampling.The survey was conducted using the general information inventory,the mishel uncertainty in illness scale for family member,the Herth hope index,and the caregiver preparedness scale.The correlation and mediating effect of disease uncertainty,hope level,and caregiver readiness were analyzed.Results The family caregivers of heart failure patients had an uncertainty score of(86.07±10.35)points,a hope level score of(35.13±4.01)points,and a caregiver readiness score of(21.45±5.09)points.Correlation analysis showed that caregiver readiness was negatively correlated with disease uncertainty(r=-0.480,P<0.01);caregiver readiness was positively correlated with hope level(r=0.419,P<0.01);disease uncertainty was negatively correlated with hope level(r=-0.433,P<0.01).Bootstrap test verified the mediating effect of hope level between disease uncertainty and caregiver readiness(β=-0.055,P<0.01),and the mediating effect accounted for 23.31% of the total effect.Conclusion The level of caregiver hope of family members of patients with heart failure partially mediates the relationship between disease uncertainty and caregiver readiness.
