Increasingly, research has explored how psychological resources enable adaptation to illness. However, it is unclear whether psychological resources protect against the potential negative effects on living well with a progressive and life-limiting condition such as dementia. This paper examines the association between psychological resources and the ability to 'live well' with dementia. Data from 1547 people with mild-to-moderate dementia in the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort were used. Multivariate linear regression was employed to examine the association between self-reported measures of psychological resources (self-efficacy, optimism and self-esteem) and indices of capability to 'live well' (quality of life, well-being and life satisfaction). All three measures of psychological resources had positive and independent associations with indices of living well and the effect sizes were similar. Effect sizes reduced when accounting for shared variance between psychological resources, showing some overlap in these constructs. Self-efficacy, optimism and self-esteem were each associated with capability to 'live well'. Overlap between these three resources is evident and when combined they may provide greater resilience when dealing with the challenges of living with dementia. Interventions for people with dementia could seek to improve levels of these potentially-modifiable psychological resources.
越来越多的研究探讨了心理资源如何帮助人们适应疾病。然而，目前尚不清楚心理资源是否能预防潜在的负面影响，比如痴呆等进行性和生命有限的疾病对生活的影响。本文探讨了心理资源与在痴呆中“生活得好”的能力之间的关系。该研究使用了轻度至中度痴呆的 1547 名参与者在改善痴呆体验和增强积极生活（IDEAL）队列中的数据。采用多元线性回归来检验自我报告的心理资源（自我效能、乐观和自尊）测量指标与“生活得好”的能力指数（生活质量、幸福感和生活满意度）之间的关联。心理资源的这三个衡量指标都与生活质量的衡量指标呈正相关且独立相关，其效应大小相似。当考虑到心理资源之间的共同方差时，效应大小会降低，这表明这些结构之间存在一定程度的重叠。自我效能、乐观和自尊都与“生活得好”的能力有关。这三种资源之间存在明显的重叠，当它们结合在一起时，可能会为应对痴呆症带来的挑战提供更大的适应能力。针对痴呆症患者的干预措施可以设法提高这些潜在可改变的心理资源水平。
