Abstract：
Chronic kidney disease (CKD) negatively impacts psychological well-being and quality of life (QoL). Underpinned by the Common Sense Model (CSM), this study evaluated the potential mediating role of self-efficacy, coping styles and psychological distress on the relationship between illness perceptions and QoL in patients living with CKD. Participants were 147 people with stage 3-5 kidney disease. Measures included eGFR, illness perceptions, coping styles, psychological distress, self-efficacy and QoL. Correlational analyses were performed, followed by regression modelling. Poorer QoL was associated with greater distress, engagement in maladaptive coping, poorer illness perceptions and lower self-efficacy. Regression analysis revealed that illness perceptions predicted QoL, with psychological distress acting as a mediator. The proportion of variance explained was 63.8%. These findings suggest that psychological interventions are likely to enhance QoL in CKD, if they target the mediating psychological processes associated with illness perceptions and psychological distress.
摘要：
慢性肾脏病（CKD）对心理健康和生活质量（QoL）产生负面影响。在常识模型(CSM)的基础上，这项研究评估了自我效能感的潜在中介作用，应对方式和心理困扰对CKD患者疾病认知与生活质量的关系.参与者是147名患有3-5期肾脏疾病的人。措施包括eGFR，疾病感知，应对方式，心理困扰,自我效能感和QoL。进行了相关分析，其次是回归建模。较差的QoL与更大的痛苦有关，参与适应不良的应对，较差的疾病认知和较低的自我效能感。回归分析显示，疾病认知预测QoL，心理困扰充当调解人。解释方差的比例为63.8%。这些结果表明，心理干预可能会提高CKD的QoL，如果它们针对与疾病感知和心理困扰相关的中介心理过程。
