N2 - Objective. To examine the construct validity of the International FItness Scale (IFIS, i.e. self-reported fitness) against objectively measured physical fitness in women with fibromyalgia and in healthy women; and study the test-retest reliability of the IFIS in women with fibromyalgia.Design. Cross-sectional study.Setting. Fibromyalgia patient support groups in Andalusia, southern Spain.Participants. 413 women with fibromyalgia and 195 healthy women (controls) for validity purposes and 101 women with fibromyalgia for the reliability study.InterventionNot 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 two occasions, one week apart.Results. Women with fibromyalgia who reported average fitness had better measured fitness compared with those reporting very poor fitness (all p
