衰老的自我认知已被认为是老年人功能残疾和死亡率的独立预测因素。尽管如此，关于衰老自我知觉的研究还是有限的。这其中的一个原因是缺乏足够的措施。具体地说，需要开发一种理论上派生的、具有良好的心理测量学特性并且本质上是多维的测量方法。本研究试图通过采用自我调节模型作为一个框架来解决这一需求，并利用它来开发一个全面的、多维的工具来评估自我对衰老的感知。这项研究描述了这一新开发的工具--老龄化感知问卷(APQ)的有效性。参与者是随机选择的2033名居住在社区的老年人(+65岁)，他们完成了APQ，并测量了身体和心理健康。APQ根据八个不同的领域或子量表评估对衰老的自我感知；其中七个领域考察了对自己衰老的看法，这些是：时间线慢性、时间线周期性、结果积极、结果消极、控制积极、控制消极和情绪表征；第八个领域是认同域，这考察了与健康相关的变化的体验。Mokken量表分析表明，关于老龄化的分量表中的大多数条目具有很强的伸缩性。验证性因素分析也表明，该模型对数据具有较好的拟合度。总体而言，各分量表具有较好的内部信度。采用分层线性回归方法考察APQ各分量表对身心健康的独立贡献，并以此确定APQ的结构效度。结果表明，衰老自我知觉与身心健康之间存在独立的相关关系。中介测验还支持衰老自我知觉在身体功能指数与身心健康结果之间的关系中起到部分中介作用。研究结果支持老龄化经历的复杂性和多面性。各分量表良好的内部信度和结构效度表明，APQ是一个很有前途的工具，可以在理论上知情的，多维度地评估自我对衰老的感知。对衰老的自我认知在促进晚年身心健康方面的潜在作用也得到了强调。
Self-perceptions of aging have been implicated as independent predictors of functional disability and mortality in older adults. In spite of this, research on self-perceptions of aging is limited. One reason for this is the absence of adequate measures. Specifically, there is a need to develop a measure that is theoretically-derived, has good psychometric properties, and is multidimensional in nature. The present research seeks to address this need by adopting the Self-Regulation Model as a framework and using it to develop a comprehensive, multi-dimensional instrument for assessing self-perceptions of aging. This study describes the validation of this newly-developed instrument, the Aging Perceptions Questionnaire (APQ). Participants were 2,033 randomly selected community-dwelling older (+65 yrs) Irish adults who completed the APQ alongside measures of physical and psychological health. The APQ assesses self-perceptions of aging along eight distinct domains or subscales; seven of these examine views about own aging, these are: timeline chronic, timeline cyclical, consequences positive, consequences negative, control positive, control negative, and emotional representations; the eighth domain is the identity domain and this examines the experience of health-related changes. Mokken scale analysis showed that the majority of items within the views about aging subscales were strongly scalable. Confirmatory factor analysis also indicated that the model provided a good fit for the data. Overall, subscales had good internal reliabilities. Hierarchical linear regression was conducted to investigate the independent contribution of APQ subscales to physical and psychological health and in doing so determine the construct validity of the APQ. Results showed that self-perceptions of aging were independently related to physical and psychological health. Mediation testing also supported a role for self-perceptions of aging as partial mediators in the relationship between indices of physical functioning and physical and psychological health outcomes. Findings support the complex and multifaceted nature of the aging experience. The good internal reliability and construct validity of the subscales suggests that the APQ is a promising instrument that can enable a theoretically informed, multidimensional assessment of self-perceptions of aging. The potential role of self-perceptions of aging in facilitating physical and psychological health in later life is also highlighted.
