Terminal change and adaptation of subjective well-being in very old age: The role of physical health and health- and death-related anxieties in the approach of the end of life

该项目旨在深入研究老年人身体健康退化的心理后果，重点关注主观幸福感（SWB）的适应。它解决了关于这一特定年龄组的研究结果方面的基本研究差距，并考虑到这种最古老的研究中死亡率的特别重要性。研究的目标是：(1)研究健康限制因素对高龄人群主观幸福感变化的影响，(2)研究物理环境背景因素的影响，以及(3)与健康和死亡相关的焦虑对这种适应性变化的影响，后两个目标都涉及在最高龄条件下的基本方面，这些方面在适应性研究中几乎没有被考虑到。在对以前生成的非常古老的样本进行后续研究后，该研究将现有数据体扩展为扩大的纵向格式，从而能够通过使用复杂的纵向方法（如生长曲线模型、生存分析）对适应性和死亡率相关变化进行深入分析。建议的研究旨在弥补对受发病率风险增加严重影响的年龄组的适应程度、限制和混杂因素缺乏了解的问题。

This project aims to contribute in-depth studies of the psychological consequences of degrading physical health in very old age, focussing on adaptation of subjective wellbeing (SWB). It addresses basic research gaps regarding findings on this particular age group and the consideration of the particular importance of mortality in such oldest-old study. The objectives are (1) to examine the impact of health constraints on changes in SWB in very old age, (2) to examine the impacts of contextual aspects of the physical environment, as well as (3) of health- and death-related anxieties on such adaptational changes, the latter objectives both addressing assumably fundamental aspects under oldest-old age conditions, which have hardly been considered in adaptation research. Following-up a previously generated sample of very old, the study serves to extend this existing data body into a enlarged longitudinal format, enabling in-depth analyses of adaptational and mortality-related changes by use of sophisticated longitudinal methodology (such as growth curve models, survival analyses). The suggested research aims to contribute to the lack of knowledge about extent, limits, and confounders of adaptation in the age group crucially affected by increasing morbidity risks.
