The aim of this study was twofold: to explore the concordance between two measures of physical activity (accelerometer and IPAQ) among female fibromyalgia (FM) patients, as well as to examine the impact of psychosocial variables (catastrophism, activity avoidance) on walking among these patients. Helplessness, activity avoidance, and commitment to physical activity were evaluated in 132 FM women. After the first assessment, an accelerometer was placed by a psychologist on each participant for seven consecutive days. Eight days later, accelerometers were collected, and participants were evaluated again using the IPAQ. Two models were tested to analyze mediation and a moderated mediation effect. The mediating role of activity avoidance between helplessness and minutes walked was corroborated regarding the objective measure of walking. The effect of helplessness on minutes walked during a week was mediated by activity avoidance and assessed by accelerometers. Cognitive variables played a contextual role when trying to promote exercise. Activity avoidance must be understood as a key variable in physical activity promotion, specifically in the promotion of walking with the aim to do exercise in individuals with FM.
探讨女性纤维肌痛（FM）患者的两种身体活动测量方法（加速度计和国际体力活动问卷[IPAQ]）之间的一致性，以及检验心理社会变量（灾难化思维、活动回避）对这些患者步行的影响。对132名患FM的女性评估了无助感、活动回避和对身体活动的投入程度。首次评估后，一名心理学家为每位参与者连续七天佩戴加速度计。八天后，收回加速度计，并再次使用IPAQ对参与者进行评估。测试了两个模型以分析中介作用和调节中介效应。就步行的客观测量而言，活动回避在无助感和步行分钟数之间的中介作用得到了证实。无助感对一周内步行分钟数的影响通过活动回避起中介作用，并由加速度计进行评估。在试图促进锻炼时，认知变量起到了背景作用。必须将活动回避理解为促进身体活动的关键变量，特别是在促进FM患者为锻炼目的而步行方面。
