COVID-19 Rehabilitation Research Methodology & Design

Simple Explanation

This study focused on translating and adapting the Post-COVID-19 Functional Status (PCFS) scale into Greek to assess its reliability and validity. The PCFS scale is used to evaluate the functional outcomes of COVID-19, helping to measure how the disease impacts a person's ability to perform daily activities. The Greek version of the PCFS was found to be reliable and valid, meaning it consistently measures what it's supposed to and accurately reflects a person's functional status after COVID-19.

Study Duration

August 2022 and January 2023

Participants

82 adults (49 females, aged 40.2 ± 6.1)

Evidence Level

Not specified

Key Findings

1
The Greek version of the PCFS (PCFS_GR) demonstrated excellent test-retest reliability with an ICC of 0.9 (95% CI 0.90-0.95).
2
The Cronbach’s alpha value was 0.9, indicating good internal consistency of the PCFS_GR.
3
PCFS_GR score were strongly correlated with the EQ-5D-5L (r = 0.6, p ≤ 0.001); and moderately to weakly correlated with the HADS.

Research Summary

The study successfully translated and adapted the Post-COVID-19 Functional Status (PCFS) scale into Greek (PCFS_GR). The Greek version of the PCFS demonstrated excellent test-retest reliability and good internal consistency, making it a reliable tool for assessing functional status post-COVID-19. The PCFS_GR is recommended for use in clinical settings and research to evaluate and monitor the functional status of Greek-speaking patients recovering from COVID-19.

Practical Implications

Clinical Assessment

The PCFS_GR provides clinicians with a reliable tool to assess functional limitations in Greek-speaking patients post-COVID-19 infection.

Research Tool

The validated PCFS_GR can be used in research to evaluate the impact of COVID-19 on functional status within the Greek population.

Treatment Planning

Assessment with PCFS_GR can inform treatment-based decisions and multidisciplinary interventions for patients recovering from COVID-19.

Study Limitations

1
The sample consisted of non-hospitalized COVID-19 patients, which may not fully represent the whole Greek post-COVID population.
2
The psychometric properties of the web-based form of the scale were not investigated.
3
The sensitivity to change (i.e. the ability of a questionnaire to detect clinical changes over time) was not assessed.
