确定影响纤维肌痛患者参加中等强度体力活动（MVPA）的心理因素。在这项次要数据分析中，170名患者接受了个性化的锻炼计划，并在第12、24和36周完成了自我报告的身体活动的基线和随访评估。结构方程模型被用来检验心理因素[运动自我效能，知觉障碍和意图]对MVPA参与的预测强度。使用每周≥10代谢当量小时的MVPA阈值增加（MET h/wk），根据以下受试者定义了三组：达到至少10 MET h/wk的增加，并持续至少12周（SUS-PA）;达到10 MET h/wk的增加，但未持续至少12周（SUS-PA）;（UNSUS-PA）;并且未实现10 MET h/wk的增加（LO-PA）。运动自我效能和意图的增加，以及感知障碍的减少与PA量的增加有关，SUS-PA的变化最大，其次是UNSUS-PA。对于LO-PA组，运动自我效能没有变化，意图减少，障碍增加。使用路径分析，运动自我效能和感知障碍与更高的身体活动量通过更大的意图，从事MVPA。对于纤维肌痛患者，运动自我效能、感知障碍和运动意图是增加体力活动的重要因素。我们的研究结果为寻求促进纤维肌痛体力活动的从业者提供了指导，并为旨在改善预测模型的研究人员提供了建议。
To identify psychological factors that influence moderate-vigorous physical activity (MVPA) participation in patients with fibromyalgia. In this secondary data analysis, 170 patients received personalized exercise plans and completed baseline and follow-up assessments of self-reported physical activity at weeks 12, 24, and 36. Structural equation modeling was used to examine the predictive strengths of psychological factors [exercise self-efficacy, perceived barriers, and intention] on MVPA participation. Using a threshold increase in MVPA of ≥10 metabolic equivalent hours per week (MET h/wk), three groups were defined based on subjects who: achieved a minimum increase of 10 MET h/wk that was sustained for at least 12 weeks (SUS-PA); achieved an increase of 10 MET h/wk that was not sustained for at least 12 weeks (UNSUS-PA); and did not achieve an increase of 10 MET h/wk (LO-PA). Increases in exercise self-efficacy and intention, and reductions in perceived barriers were associated with increased volume of PA, showing the greatest change in the SUS-PA, followed by UNSUS-PA. For the LO-PA group, there was no change in exercise self-efficacy, a decrease in intention, and an increase in barriers. Using path analysis, exercise self-efficacy and perceived barriers were associated with higher volumes of physical activity via greater intention to engage in MVPA. For patients with fibromyalgia, exercise self-efficacy, perceived barriers, and intention to exercise are important constructs for increasing physical activity. Our findings provide guidance for practitioners who seek to promote physical activity in fibromyalgia, and suggestions for researchers aiming to improve prediction models.
