The fear-avoidance model is an attempt to underscore the importance of cognitive and behavioral factors, in a chain of events linking pain to disability. However, it is not clear at what time point the psychological variables within the model begin to be prominent. The aim of this study was to investigate the role of these psychological variables in the development of a chronic musculoskeletal pain problem. Three stages of chronicity, defined by duration of pain, provided a proxy for the developmental process: <1 year (N=48), 1-3 years (N=47) and >3 years (N=89). Subjects completed questionnaires on fear of movement, catastrophizing, depression, pain and function. The results indicate that the relationship between fear of movement and function is moderated by the stage of chronicity. Regression analyses showed that fear of movement did not explain any variance in the group with pain duration <1 year. Fear of movement did explain variance in the groups with pain duration of 1-3 years and >3 years. This suggests that the time point in the development of a musculoskeletal pain problem might be an essential aspect of the importance of the relationship between psychological components and function.
恐惧回避模型试图强调认知和行为因素在将疼痛与残疾联系起来的一系列事件中的重要性。然而，尚不清楚该模型中的心理变量在何时开始变得突出。本研究的目的是调查这些心理变量在慢性肌肉骨骼疼痛问题发展中的作用。根据疼痛持续时间定义的慢性三个阶段为发展过程提供了一个替代指标：<1年（N = 48）、1 - 3年（N = 47）和>3年（N = 89）。受试者完成了关于运动恐惧、灾难化、抑郁、疼痛和功能的问卷调查。结果表明，运动恐惧与功能之间的关系受慢性阶段的调节。回归分析表明，运动恐惧在疼痛持续时间<1年的组中不能解释任何方差。运动恐惧在疼痛持续时间为1 - 3年和>3年的组中能解释方差。这表明肌肉骨骼疼痛问题发展中的时间点可能是心理成分与功能之间关系重要性的一个关键方面。
