Chilean version of the Functional Status Score for the Intensive Care Unit: a translation and cross-cultural adaptation

Background The Functional Status Score for the Intensive Care Unit (FSS-ICU) is a valid and reliable instrument to measure physical functioning in the intensive care unit setting. Translation and cross-cultural adaptation in Chile has not been published for the FSS-ICU. Aim To translate and cross-culturally adapt all associated documents of the original FSS-ICU for Chile. Method The Spanish version of FSS-ICU, available at www.ImproveLTO.com, was used as the starting point. This version was previously translated, with the original FSS-ICU developers, following established guidelines for this pro-cess. The Chilean pocket card version was newly developed based on the English version at www.ImproveLTO.com. Cognitive interviews were con-ducted for the adaptation of the FSS-ICU and pocket card version to assess understanding of relevant stakeholders (i.e., Chilean intensive care unit phy-siotherapists). Adaptations to the translation were made when agreement among the physiotherapists was less than 80%. Results Cognitive interviews of the Chilean FSS-ICU (85 items) and pocket card version (18 items) were performed with 30 Chilean physiotherapists from 18 hospitals (14 public and 4 private). During the interviews, modest adaptations mainly made in the general guidelines and specific instructions for three items of the FSS-ICU and two items of the pocket card. Finally, the frequently asked questions, pocket card and full version of the FSS-ICU were developed. The original developers accepted all adaptations. Conclusions The Chilean version of the FSS-ICU was easy to understand by the physiotherapists. The FSS-ICU is freely available for non-commercial clinical and research use by Chilean Spanish-speakers. © 2019, Medwave Estudios Ltda. All rights reserved.
