Translation and psychometric properties of the Gujarati version post-COVID functional status scale

Abstract

The ‘Post COVID Functional Status Scale’ (PCFS) is an ordinal scale concentrating on the functional limitations to view the variety of post-COVID 19 outcomes and to measure the consequence of the infection other than death The adapted version of the PCFS Scale will be useful in tracking the post COVID functional status in the individuals who can comprehend the scale better in the Gujarati language. This study was carried out in a post-COVID-19 patient population at a government tertiary care hospital. The study was carried out according to the guidelines given by the American Association of Orthopaedic Surgeons. The methodology consisted of 3 Phases. Forward and backward translation, expert committee review, and usability testing on the participants who were asked to fill out the Gujarati version of the PCFS scale twice in Phase 1, 2, and 3 respectively.30 participants, both males, and females participated in the study. Cronbach’s α was used to calculate the internal consistency of the scale. The ICC was 0.99, which interprets as a very high correlation and stability of the scale.The Cronbach’s alpha was calculated for a population of 30 participants. On test 1 the value for Cronbach’s Alpha (ɑ1) was 0.821 and on the second test, the value was (ɑ2) 0.866. A linguistically and practically identical Gujarati PCFS Scale was formulated after a careful and systematic process, which offers a viable and trustworthy method for assessing the functionality of post-COVID-19 patients.
