We examined how physical pain impacts the developmental construct of Awareness of Age-Related Change (AARC-gains and AARC-losses) and, in turn, how AARC mediates and moderates the association between pain and subsequent physical activity. We used longitudinal data from 434 participants of the UK PROTECT Study (mean age = 65.5 years; SD = 6.94 years). We found that pain in 2019 predicted higher AARC-losses (β = .07; p = .036) and less physical activity (β = -.13; p-value = .001) in 2020. Additionally, we found that AARC-losses partially mediated, but did not moderate, the association of pain in 2019 and physical activity in 2020. AARC-losses may explain physical inactivity in middle-aged and older adults experiencing pain. Incorporating developmental constructs such as AARC into theories and empirical studies on pain and pain management may be necessary to more fully capture people's responses to pain.

年龄相关变化的意识在疼痛和身体活动之间的纵向关联中的作用。

我们研究了身体疼痛如何影响年龄相关变化意识（AARC 增益和 AARC 损失）的发展结构，以及 AARC 如何介导和调节疼痛与随后身体活动之间的关联。我们使用了英国 PROTECT 研究 434 名参与者的纵向数据（平均年龄 = 65.5 岁；SD = 6.94 岁）。我们发现，2019 年的疼痛预示着 2020 年 AARC 损失会更高（β = .07；p = .036），体力活动也会减少（β = -.13；p 值 = .001）。此外，我们发现 AARC-损失部分介导了 2019 年疼痛与 2020 年身体活动的关联，但并未减弱。AARC 损失可以解释中老年人经历疼痛时缺乏身体活动的原因。将 AARC 等发展结构纳入疼痛和疼痛管理的理论和实证研究中，可能有必要更全面地捕捉人们对疼痛的反应。
