Psychometric Testing of the Multidimensional Older People's Quality of Life Questionnaire, 2007-2008

<P>Abstract copyright UK Data Service and data collection copyright owner.</P><br>Increasing social expectations and concerns about the policy implications of the ageing population have led to interest in improving older people's health, independence, activity, social and economic opportunities and participation, thereby their active contribution to society and, in effect, adding quality to extended years. Assessment of the effectiveness of public policy in this area requires the use of relevant and valid measurement instruments, based on a sound conceptual model. The purpose of the study was to test a new measure of quality of life (QoL) in older age, and the robustness of the causal model under-pinning it dynamically in an ageing population. In this process, the research will provide information on the links between influences on QoL, the process of active ageing and perceived QoL.<br><B>Main Topics</B>:<BR><br>- To test the OPQOL cross-sectionally and dynamically for data quality, acceptability, scaling, item-reduction, reliability and validity in a cross-section sample of people aged 65+ and in a dynamic ageing population sample. <br>
<br>
- To elicit older people's understandings and self-ratings of 'active ageing', and its influence on QoL and to compare these with theoretical models.<br>
<br>
- To examine the direct and indirect influences of self-efficacy and perceived control on indicators, and perceptions, of active ageing and QoL in a dynamic, ageing population sample. <br>
<br>
- To identify the pathways between active ageing and perceived QoL in a dynamic, ageing population sample.<br>

社会对人口老龄化政策影响的关注度与日俱增，公众期待亦不断提升，这使得改善老年人健康状况、自主能力、活动水平、社会与经济机遇及参与度，进而推动其为社会作出积极贡献，并切实提升晚年生活质量成为研究热点。评估该领域公共政策的实施成效，需依托合理的概念模型，采用相关且有效的测量工具。本研究旨在针对老年人群体，检验全新的生活质量（Quality of Life, QoL）测量工具，以及支撑该工具的因果模型在老龄化人口群体中的动态稳健性。在此过程中，本研究将揭示生活质量影响因素、积极老龄化进程与感知生活质量之间的关联机制。

**核心研究主题**：
- 针对65岁及以上人群的横断面样本与动态老龄化人口样本，从数据质量、可接受性、量表结构、题项精简、信度与效度层面，对OPQOL量表开展横断面与动态性检验。

- 征集老年人对"积极老龄化"的认知与自评结果，及其对生活质量的影响，并将相关结论与理论模型进行比对。

- 在动态老龄化人口样本中，检验自我效能感与感知控制对积极老龄化及生活质量的相关指标与感知结果的直接与间接影响。

- 在动态老龄化人口样本中，厘清积极老龄化与感知生活质量之间的作用路径。
