Two studies are reported that tested the fear-avoidance (FA) model using path analytic techniques. In study 1, 429 employees with back pain at baseline and back pain at 18 months follow-up completed questionnaires assessing sociodemographic information, pain severity, negative affect, pain-related fear, and disability. Results indicated that pain severity at baseline predicted pain-related fear and disability at follow-up, and that pain-related fear is rather a consequence than an antecedent of pain severity. Results further revealed that the disposition to experience negative affect has a low impact upon pain severity and disability, and is best viewed as a precursor of pain-related fear. Study 2 included 238 employees without back pain at baseline, but who developed back pain at 1 year follow-up. A similar model as in study 1 was tested. Overall, results are in line with those of study 1. Results are discussed in terms of theoretical relevance and clinical implications.
有两项研究采用路径分析技术检验了恐惧回避（FA）模型。在研究 1 中，429 名基线时有背痛和 18 个月随访时有背痛的员工完成了评估社会人口统计学信息、疼痛严重程度、负性情绪、与疼痛相关的恐惧和残疾的问卷。结果表明，基线时的疼痛严重程度预测了随访时的与疼痛相关的恐惧和残疾，并且与疼痛相关的恐惧更多是疼痛严重程度的结果而不是其原因。结果还表明，体验负性情绪的倾向对疼痛严重程度和残疾的影响较小，最好将其视为与疼痛相关的恐惧的前兆。研究 2 包括 238 名基线时没有背痛但在 1 年随访时出现背痛的员工。检验了与研究 1 类似的模型。总体而言，结果与研究 1 的结果一致。根据理论相关性和临床意义讨论了结果。
