Translation, intercultural adaptation, and validation of the Slovak version of AOSpine patient reported outcome for spinal trauma tool

Abstract

Objectives: The implementation of patient-reported outcome measurements has become a standard component of evaluating the effect of treatment. For spine injuries, an evaluation tool AOSpine Patient Reported Outcome for Spinal Trauma (AOSpine PROST) has been developed. The aim of this study was to translate, interculturally adapt and validate the Slovak version of AOSpine PROST.

Methods: Based on methodologies we translated and culturally adapted the AOSpine PROST into Slovak. We then validated it on a representative sample of patients treated at a single level‑one trauma center in the Slovak Republic. Content validity was assessed by evaluating the number of inapplicable or missing questions. Internal consistency was assessed by calculating Cronbach's alpha and Corrected item-total correlations.

Results: 37 patients were included in the study. The questionnaire was understandable to patients. The mean T-score across questions and participants in the questionnaire was 79.6 with a narrow range of 70.4 to 97.3 for all questions, which is relatively high. The internal consistency of total score was excellent with Cronbach´s alpha of 0.92. Total correlation across questions revealed relatively good results ranging from 0.17 to 0.90.

Conclusions: The results indicate that the Slovak version of AOSpine PROST is reliable and valid and can be used in practice (Tab. 2, Ref. 14). Text in PDF www.elis.sk Keywords: AOSpine PROST, patient reported outcome, spinal trauma, translation, intercultural adaptation.
