OBJECTIVE: To describe and compare the process of transcultural adaptation in the 4 validated Spanish versions of the Fibromyalgia Impact Questionnaire (FIQ). MATERIAL AND METHODS: a) Questionnaires. The first version (FIQ1) appeared as a doctoral thesis in 1988; the second (FIQ2) was published in a Spanish psychology journal; the third (FIQ3) was published in an English language journal; and the last (FIQ4) appeared in November 2004 in the Revista Española de Reumatología. b) Methods In each of the versions the following were assessed: 1) the semantic equivalence with respect to the original FIQ, 2) each version's degree of development following a standardized method based on the GRAQoL Index (GI), and 3) the impact of publication. RESULTS: The FIQ4 showed a greater semantic equivalency. The degree of development shown by the GI produced the following results: FIQ1, 56%; FIQ2, 50%; FIQ3, 75%; FIQ4, 31%. Only the FIQ3 results were published in Medline-indexed journals. CONCLUSION: The Spanish FIQ3 version presents a greater degree of development and an acceptable semantic equivalency with respect to the original, and has achieved a greater impact.
