Exercise and physical activity are an evidence-based practice for chronic pain. Health professionals need instruments to assess self-efficacy for this practice taking into account the specific barriers of patients with these health problems.
To develop and test the psychometric properties of a new self-efficacy scale for physical activity and walking exercise in patients with fibromyalgia.
A cross-sectional and prospective study was conducted in a Spanish Fibromyalgia Unit. Two hundred and eleven new patients signed the informed consent and participated in the study. All of them were women, referred to by either Primary or Specialized Health Care. In addition to the new scale, they filled out several self-reported and validated instruments to collect the data present in this study.
Exploratory factor analysis showed a three-factor model (GFI = .99; RMSR = .06) that explained 74.2% of the total variance. They assessed how confident patients felt about walking quickly in both 30- and 60-minute sessions, (Factor I: 10 items; α = .97), to perform daily physical activities (Factor II: 10 items; α = .93) and to undertake moderate physical activity (Factor III: 5 items; α = .95). The total score of the scale and the three-factor scores showed good criterion validity and adequate validity based on the relationships with other constructs.
The scale showed adequate psychometric properties and can be a useful tool to help health professionals monitor patients' self-efficacy perception and customize both physical activity and walking exercise intervention goals and their implementation.
运动和身体活动是慢性疼痛的循证实践。健康专业人员需要使用评估自我效能的工具，考虑到患有这些健康问题的患者的具体障碍。
开发和测试一种新的针对纤维肌痛症患者身体活动和步行锻炼的自我效能量表，并检验其心理测量学特性。
这是一项在西班牙纤维肌痛症科进行的横断面前瞻性研究。211 名新患者签署了知情同意书并参与了研究。他们均为女性，由初级保健或专科保健转介而来。除了新量表外，他们还填写了几个自我报告和经过验证的工具，以收集本研究中的数据。
探索性因素分析显示，三因素模型（GFI=.99；RMSR=.06）可解释总方差的 74.2%。该模型评估了患者对快走的信心，分别在 30 分钟和 60 分钟的时间内进行（因子 I：10 个项目；α=.97），完成日常体力活动（因子 II：10 个项目；α=.93）和进行中等强度的体力活动（因子 III：5 个项目；α=.95）。该量表的总分和三个因子分数具有良好的效标效度和基于与其他结构关系的充分有效性。
该量表具有良好的心理测量学特性，可作为一种有用的工具，帮助健康专业人员监测患者的自我效能感，并针对身体活动和步行锻炼干预目标及其实施情况进行个性化调整。
