OBJECTIVES
To examine the construct validity of the International FItness Scale (IFIS) (ie, self-reported fitness) against objectively measured physical fitness in women with fibromyalgia and in healthy women; and to study the test-retest reliability of the IFIS in women with fibromyalgia.
DESIGN
Cross-sectional study.
SETTING
Fibromyalgia patient support groups.
PARTICIPANTS
Women with fibromyalgia (n=413) and healthy women (controls) (n=195) for validity purposes and women with fibromyalgia (n=101) for the reliability study. The total sample was N=709.
INTERVENTIONS
Not applicable.
MAIN OUTCOME MEASURES
Fitness level was both self-reported (IFIS) and measured using performance-based fitness tests. For the reliability study the IFIS was completed on 2 occasions, 1 week apart.
RESULTS
Women with fibromyalgia who reported average fitness had better measured fitness than those reporting very poor fitness (all P<.001, except 6-minute walk test where P<.05), with similar trends observed in healthy control women. The test-retest reliability of the IFIS, as measured by the average weighted κ, was .45.
CONCLUSIONS
The IFIS was able to identify women with fibromyalgia who had very low fitness and distinguish them from those with higher fitness levels. Furthermore, the IFIS was moderately reliable in women with fibromyalgia.
目的
在纤维肌痛女性患者和健康女性中，检验国际健身量表（IFIS）（即自我报告的健康状况）相对于客观测量的身体健康状况的结构效度；并研究IFIS在纤维肌痛女性中的重测信度。
设计
横断面研究。
地点
纤维肌痛患者支持小组。
参与者
为检验效度，纳入纤维肌痛女性患者（n = 413）和健康女性（对照组）（n = 195）；为进行信度研究，纳入纤维肌痛女性患者（n = 101）。总样本量为N = 709。
干预措施
不适用。
主要观察指标
健康状况通过自我报告（IFIS）和基于表现的体能测试来测量。在信度研究中，IFIS分两次完成，间隔1周。
结果
报告平均健康水平的纤维肌痛女性，其测量的健康状况优于报告健康状况很差的女性（除6分钟步行试验P <.05外，其余均P <.001），健康对照女性中也观察到类似趋势。通过平均加权κ系数测量，IFIS的重测信度为0.45。
结论
IFIS能够识别健康状况非常差的纤维肌痛女性，并将她们与健康状况较好的女性区分开来。此外，IFIS在纤维肌痛女性中具有中等可靠性。
