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(More)
Objective. To test the gender differences in tenderness, impact of fibromyalgia, health-related quality of life, fatigue, sleep quality, mental health, cognitive performance, pain-cognition, and positive health in Spanish fibromyalgia patients and in age-matched nonfibromyalgia individuals from the same region. To test the optimal cut-off score of the(More)
OBJECTIVE This population-based cross-sectional study aimed to characterize the association of different components of physical fitness with pain levels, pain-related catastrophizing, and chronic pain self-efficacy in women with fibromyalgia (FM). METHODS A total of 468 women with FM participated. The experience of pain was assessed with different tools(More)
We examined the association of objectively measured sedentary time (ST) and physical activity (PA) levels with pain, fatigue, and the impact of the disease in women with fibromyalgia. Four hundred and nineteen (mean age ± SD = 51.7 ± 7.6 years old) women with fibromyalgia participated. ST and PA levels (light, moderate, and moderate-to-vigorous [MVPA]) were(More)
OBJECTIVE The aim of this study was to validate the modified 2010 ACR preliminary criteria for FM in a Spanish population. METHODS Five hundred and seventy-nine (550 women) FM and 294 (240 women) control participants were enrolled in the study. FM patients were previously diagnosed by a rheumatologist. All participants underwent both the 1990 ACR criteria(More)
Objectives The aim of this study was to identify subgroups in terms of adaptation to FM and to test differences in FM severity between these subgroups. Methods The al-Ándalus project made it possible to perform a comprehensive population-based cross-sectional study in 486 FM patients including multiple assessments of modifiable (could be targeted in(More)
PURPOSE People with fibromyalgia experience a disagreement between patient-reported (i.e., subjective) and performance-based (i.e., objective) status. This study aimed to (i) corroborate the discordance between subjectively and objectively measured physical function and (ii) examine whether catastrophizing (worrying, pain magnifying, and helpless(More)
The present study aimed: (1) to test the associations of overall physical fitness and subjective well-being with fibromyalgia severity and (2) to determine whether the combination of overall physical fitness and subjective well-being is associated with fibromyalgia severity among adult women patients. This cross-sectional study included 424 participants(More)
BACKGROUND The al-Andalus physical activity intervention study is a randomised control trial to investigate the effectiveness of a land- and water-based exercise intervention for reducing the overall impact of fibromyalgia (primary outcome), and for improving tenderness and pain-related measures, body composition, functional capacity, physical activity and(More)
OBJECTIVE To characterize the levels of objectively measured time spent in sedentary activities (sedentary time) and physical activities in female patients with fibromyalgia and compare them with the levels in age-matched healthy control women. METHODS The study comprised 413 female patients with fibromyalgia (mean ± SD age 51.9 ± 7.4 years) and 188(More)
