Arabic translation and psychometric testing of the self-screening malnutrition universal screening tool in inflammatory bowel disease patients

Objectives: To translate and validate the malnutrition universal screening tool (MUST) for use in Arabic-speaking outpatients with inflammatory bowel disease (IBD). Methods: We translated the MUST into Arabic by using the Brislin back-translation method. This methodological study was performed between August 2016 and November 2017 on 143 outpatients with IBD at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. The patients must completed the self-administered (PSA) Arabic version of the MUST. Then, the health-care practitioners (HCPs) administered the Arabic MUST and performed standard patient clinical assessment. The nutrition risk was defined as low (MUST score=0), medium (MUST score=1), or high (MUST score >1). The chance-corrected proportional agreement between the scores from the PSA and HCP-administered Arabic MUST was evaluated using Cohen's kappa coefficient. Internal consistency was evaluated using Cronbach's alpha statistic. Results: The overall agreement between the PSA and HCP-administered Arabic MUST was almost perfect (agreement=95.9%, expected agreement=72.4%, kappa=0.85, p<0.0001). The calculated Cronbach's alpha statistic for MUST scores in 15/143 (10%) patients was 0.79. The calculated Pearson's correlation coefficient between PSA and HCP-administered MUST scores was 0.93 (p<0.0001). Conclusions: The PSA and HCP-administered Arabic MUST showed perfect agreement in outpatients with IBD.
