The aim of this study was to develop a Greek-language version of the MFPDI and to assess the instrument's psychometric properties.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The MFPDI was translated into Greek by three bilingual content experts and two bilingual language experts, and then back-translated into English to assess for equivalence. The final Greek version was administered, along with a questionnaire consisting medical history and the Medical Outcomes Study Short Form 36 (SF-36), to 104 Greek-speaking, community-dwelling people (64 female, 40 male), aged between 64 and 90 years (mean 73.00, SD 5.26) with disabling foot pain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The Greek translation of the MFPDI was found to have high internal consistency (Cronbach's \u03b1= 0.89, and item-total correlation coefficients from 0.33 to 0.72). Principal components analysis revealed a four-factor structure representing the constructs of functional limitation, pain intensity, concern with appearance and activity restriction, which explained 60.8% of the variance, with 38.9% of the variance explained by the first construct (functional limitation). Six items demonstrated different factor loadings to the original English version.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The Greek-language version of the MFPDI appears to be a valid tool in assessing foot pain in Greek-speaking older people. The total MFPDI scores are comparable between the Greek and English version, however due to differences in the factor loadings of some items, between-language comparisons of MFPDI should be undertaken with some caution.<\/jats:p><\/jats:sec>","DOI":"10.1186\/1477-7525-6-39","type":"journal-article","created":{"date-parts":[[2008,6,3]],"date-time":"2008-06-03T06:13:13Z","timestamp":1212473593000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Development and validation of a Greek language version of the Manchester Foot Pain and Disability Index"],"prefix":"10.1186","volume":"6","author":[{"given":"Patricia","family":"Kaoulla","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicoletta","family":"Frescos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hylton B","family":"Menz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2008,6,1]]},"reference":[{"issue":"6","key":"441_CR1","doi-asserted-by":"publisher","first-page":"308","DOI":"10.7547\/87507315-77-6-308","volume":"77","author":"JR Black","year":"1987","unstructured":"Black JR, Hale WE: Prevalence of foot complaints in the elderly.
