Fatigue is known to interfere with function in individuals with physical disabilities. In order to monitor changes in fatigue over time and evaluate the efficacy of treatments, psychometrically sound measures of fatigue are needed. The aim of this work was to evaluate the validity of the Silhouettes Fatigue Scale with English instructions (SFS-EN) in a sample of adults with physical disabilities living in the USA.
Individuals with medical conditions associated with physical disabilities responded to an online survey that included the SFS-EN as well as another validated measure of fatigue (PROMIS short form-4a Fatigue Scale), and measures of pain intensity and pain catastrophizing.
523 individuals participated (mean age = 59.1 years; = 11.4). Most participants were Caucasian (89%), women (59%) and unemployed (71%). Results showed strong positive correlations between both measures of fatigue, supporting the convergent validity of the SFS-EN. In addition, the magnitude of this association was significantly greater than the association between the scores of the SFS-EN and the measures of pain intensity and pain catastrophizing, supporting the former's discriminant validity.
The findings extend previous results supporting the SFS as a brief, easy to administer and understand, and valid measure of fatigue.IMPLICATIONS FOR REHABILITATIONFatigue is common in adults with physical disabilities and chronic pain.The Silhouettes Fatigue Scale (SFS) is a new single-item measure of general fatigue.Findings show that the SFS with English instructions (SFS-EN) is an easy to understand measure.Results support the convergent and discriminant validity of the SFS-EN score in adults with physical disabilities and chronic pain.
众所周知，疲劳会干扰身体残疾者的功能。为了监测疲劳随时间的变化并评估治疗效果，需要心理测量学上可靠的疲劳测量方法。这项工作的目的是在美国生活的身体残疾成年人样本中评估带有英文说明的轮廓疲劳量表（SFS - EN）的有效性。
患有与身体残疾相关疾病的个体对一项在线调查做出回应，该调查包括SFS - EN以及另一种经过验证的疲劳测量方法（患者报告结果测量信息系统简表 - 4a疲劳量表），还有疼痛强度和疼痛灾难化的测量方法。
523名个体参与了研究（平均年龄 = 59.1岁；标准差 = 11.4）。大多数参与者是白人（89%）、女性（59%）且失业（71%）。结果显示两种疲劳测量方法之间存在强正相关，支持了SFS - EN的收敛效度。此外，这种关联的程度显著大于SFS - EN得分与疼痛强度和疼痛灾难化测量方法之间的关联，支持了前者的区分效度。
研究结果扩展了先前的结果，支持SFS作为一种简短、易于实施和理解且有效的疲劳测量方法。
对康复的启示
疲劳在患有身体残疾和慢性疼痛的成年人中很常见。
轮廓疲劳量表（SFS）是一种新的单一项目的一般疲劳测量方法。
研究结果表明带有英文说明的SFS（SFS - EN）是一种易于理解的测量方法。
结果支持了SFS - EN得分在患有身体残疾和慢性疼痛的成年人中的收敛效度和区分效度。
