Reliability and Validated Arabic Version of DRIVE4COPD

Abstract

Background: COPD is a debilitating condition and projected to be the third leading cause of death worldwide by 2030. DRIVE4COPD is one of instrument used to assess COPD risk in population and original version of DRIVE4COPD (English) is valid and reliable. In this study we aimed to assess reliability and validated Arabic version of DRIVE4COPD questionnaire. The study was approved by the institutional ethical committee at Batterjee Medical College (BMC) (RES 2022-42.)

Methods: The DERIVE4COPD questionnaire contains 5 items of total score 10 which indicted to high risk of COPD and 0 low risk. This questionnaire was translated into Arabic version and reviewed by an expert panel before being back-translated into English. The Arabic version was administered to 6 Arabic participants to test whether it was easily understood after which a final Arabic version was produced. Thereafter, 30 participants with average age of 40 years (63% male) conducted spirometry and completed the Arabic version of DRIVE4COPD, COPD Assessment Test (CAT) and The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). The DRIVE4COPD was re-administered two week later to same participants.

Results: The Arabic version of the DRIVE4COPD questionnaire demonstrated excellent reliability over the two-period administration (intraclass correlation coefficient = 0.979, P = .004. The DRIVE4COPD consisted of 5 items and the value for Cronbach’s alpha for the survey was α = 0.979. the test-retest correlation between each question over the two times were (Q1, r = 0.90. Q2, r = 0.49. Q3, r = 0.76. Q4, r = 1.0. Q5 r = 0.90), respectively. Additionally, to assess the validity of the Arabic version of the DRIVE4COPD questionnaire, Cohen's κ was run to determine if there was agreement between DRIVE4COPD result and spirometry for the 30 participants. The results indicated moderate agreement between the translated tool and the spirometry result, κ = .50 (95% CI 0.331 to 0.669), P = .004. Moreover, the DRIVE4COPD indicated a sensitivity 50% and specificity 95%. Finally, strong associations were demonstrated between the total score of DRIVE4COPD, and FACIT-F score (r = 0.61; P ≤ .001) and with CAT score (roh = 0.71; P ≤ .001).

Conclusions: The Arabic version of the DRIVE4COPD is a reliable and valid instrument to assess risk of COPD among Arab society.
