活动模式被认为在慢性疼痛的发展和持续中起重要作用。到目前为止，已经研究了三种重要的活动模式：回避行为，坚持行为和起搏行为。然而，经验证据是有限的，这些活动模式和重要成果之间的关系是不确定的。因此，本研究的目的是通过因素分析确定活动模式，并确定其与残疾和抑郁症的参与者与慢性疼痛（N = 132）。汇总了与1种特定活动模式有关的不同测量工具的项目，并提交给因素分析。从3个独立的因素分析的结果显示6个不同的活动模式：疼痛回避，活动回避，任务相关的持久性，过度持久性，疼痛相关的持久性，和起搏。与我们的假设一致，疼痛和活动回避，以及过度的持久性，与更高水平的残疾和抑郁症相关。与假设相反，起搏也与更差的结局相关。有趣的是，任务相关的持久性与较低水平的残疾和抑郁症相关。当控制疼痛和其他活动模式时，过度的坚持和活动回避在与抑郁情绪或残疾的关系方面是最有害的。任务相关的持久性似乎是最有害的。视角：我们的研究结果表明，存在几种活动模式，这是差异相关的残疾和抑郁症，在参与者慢性疼痛。目前的研究结果进行了讨论，根据以前的研究结果，并可能提供一个新的动力，为未来的研究活动模式在慢性疼痛的研究。(C)2011年美国疼痛协会American Pain Society
Activity patterns are believed to play an important role in the development and perpetuation of chronic pain. So far, 3 important activity patterns have been studied: avoidance behavior, persistence behavior, and pacing behavior. Yet, empirical evidence is limited and inconclusive about the relationships between these activity patterns and important outcomes. Therefore, the present study was aimed at identifying activity patterns by means of factor analyses and determining their relationship with disability and depressive symptomatology in participants with chronic pain (N = 132). Items across different measurement instruments pertaining to 1 particular activity pattern were aggregated, and submitted to factor analysis. Results from 3 separate factor analyses revealed 6 distinct activity patterns: pain avoidance, activity avoidance, task-contingent persistence, excessive persistence, pain-contingent persistence, and pacing. In line with our hypotheses, pain and activity avoidance, and excessive persistence, were related to higher levels of disability and depressive symptomatology. In contrast to hypotheses, pacing was associated with worse outcomes as well. Interestingly, task-contingent persistence was related to lower levels of disability and depressive symptomatology. When controlling for pain and the other activity patterns, excessive persistence and activity avoidance were the most detrimental in terms of relations with depressed mood or disability. Task-contingent persistence appeared to be the least detrimental. Perspective: Our findings suggest the existence of several activity patterns, which are differentially related to disability and depressive symptomatology, in participants with chronic pain. The present results are discussed in the light of previous findings, and may provide a new impetus for future studies on activity patterns in chronic pain research.
