ABSTRACT

Previous work has shown that event-based prospective memory (EBPM) predicted health-related quality of life (HrQoL). In the present study, we aimed to examine whether the relationship between EBPM and HrQoL extended to life satisfaction, and whether it persisted after controlling for other cognitive functions related to EBPM, namely executive functions and retrospective memory. We tested two models using structural equation modeling with latent variables in a sample of older adults. In the first model, we assessed whether EBPM predicted life satisfaction and HrQoL; in the second model, we controlled for retrospective memory and executive functions. The first model indicated that EBPM was related to HrQoL. However, in the second model, this relationship was eliminated by executive functions; life satisfaction was not related to any of the cognitive variables. Findings corroborated the link between HrQoL and EBPM, suggesting that such relationship stems from executive functions rather than retrospective memory.

摘要

以前的工作表明，基于事件的前瞻性记忆 (EBPM) 可以预测与健康相关的生活质量 (HrQoL)。在本研究中，我们旨在检查 EBPM 和 HrQoL 之间的关系是否扩展到生活满意度，以及在控制与 EBPM 相关的其他认知功能（即执行功能和回顾记忆）后是否持续存在。我们在老年人样本中使用具有潜在变量的结构方程模型测试了两个模型。在第一个模型中，我们评估了 EBPM 是否可以预测生活满意度和 HrQoL；在第二个模型中，我们控制了追溯记忆和执行功能。第一个模型表明 EBPM 与 HrQoL 相关。然而，在第二种模式中，这种关系被行政职能所消除；生活满意度与任何认知变量无关。调查结果证实了 HrQoL 和 EBPM 之间的联系，表明这种关系源于执行功能而不是回顾性记忆。
