RT Journal Article T1 The Impairment and Functioning Inventory Revised-Englishversion: A validation study in individuals with disabilitiesand bothersome pain A1 Ramírez-Maestre, María del Carmen A1 Esteve-Zarazaga, Rosa A1 López-Martínez, Alicia Eva A1 Jensen, Mark P. A1 Miró, Jordi A1 De la Vega, Rocío K1 Dolor (Psicología) AB The purpose of this study was to evaluate the psychometric properties of an English version of the Impairment and Functioning Inventory Revised (IFI-R-EV) in a sample of individuals with bothersome pain from the USA. In 2015, the IFI-R was revised using data from a Spanish sample of 483 individuals with back pain who were treated at primary care centres, and 137 patients with various pain conditions who were treated at a pain clinic. This process resulted in a revised version of the IFI (IFI-R) that was published in PM&R journal (Ramirez-Maestre, C., & Esteve, R, 2015: A new version of the Impairment and Functioning Inventory for patients with chronic pain (IFI-R). PM&R, 7(5), 455-465).The findings indicate that the English version of the IFI-R (presented in this article) provides valid and reliable measures of daily function and impairment in English-speaking individuals with a disability and chronic pain.
