    <title language="eng">Measuring health in patients with fibromyalgia: Content comparison of questionnaires based on the International Classification of Functioning, Disability and Health (ICF)</title>
    <abstract language="eng">Objective&#13;
To analyze the content of outcome measures commonly used to assess health in patients with fibromyalgia (FM) by linking the items of the instruments with the International Classification of Functioning, Disability and Health (ICF) in order to evaluate the adequacy of currently used measures.&#13;
&#13;
Methods&#13;
Questionnaires used in FM were identified in a structured literature search. All concepts included in the items of the questionnaires were linked to ICF categories, according to previously published linking rules, by 2 independent health professionals. The percentages of linked ICF categories addressing the different ICF components were calculated.&#13;
&#13;
Results&#13;
Generic and symptom‐specific instruments were included. From the 296 items contained in all 16 instruments, 447 concepts were extracted and then linked to 52 ICF categories of the component body functions, 1 category of the component body structure, 40 categories of the component activities and participation, and 9 categories of the component environmental factors. More than half of the concepts identified were linked to body function, fewer were linked to activities and participation, and only concepts of 4 instruments were linked to the ICF component environmental factors.&#13;
&#13;
Conclusion&#13;
Many concepts were linked to the categories in the ICF component body functions. While linking to the broad category, purportedly similar instruments often covered widely varying areas of function at more fine‐grained levels of detail. Some categories, such as environmental factors, were barely covered by any of the instruments and might constitute an important aspect of health deserving better coverage and future development.</abstract>

    <title language="eng">Measuring Functioning in People with Fibromyalgia (FM) Based on the International Classification of Functioning, Disability and Health (ICF)—A Psychometric Analysis</title>
    <abstract language="eng">Objectives: Instruments to assess functioning in patients with FM vary considerably in their content and are often symptom‐specific. This study aimed to examine whether it is feasible to construct a psychometric‐sound clinical instrument to measure functioning in FM based on the Brief ICF‐Core‐Set for chronic widespread pain (CWP). &#13;
&#13;
Methods: Two hundred and fifty six people with FM completed the Brief ICF‐Core‐Set. The Rasch model was used for analysis. Once ordering of response options of ICF categories was ensured, the following properties were studied: fit of the ICF categories to the Rasch model, the targeting between ICF categories and a person’s abilities, unidimensionality, and reliability. &#13;
&#13;
Results: Six ICF categories were rescored due to disordered thresholds. Five ICF categories were removed due to high model‐misfit and differential item functioning (DIF) for gender. Scores from 46 participants were excluded due to extreme scores. The ICF categories included display consistency with an underlying unidimensional construct, are free of DIF for age, disease duration and gender, display excellent overall reliability, and cover a range of functioning difficulties. &#13;
&#13;
Conclusions: This study illustrates that it is possible to measure functioning as a unidimensional construct based on selected ICF categories from the components body functions, as well as activities and participation of the Brief ICF‐Core‐Set for CWP in patients with FM.</abstract>
