Translation and Cross-Cultural Adaptation of an Arabic Version of the Summated Xerostomia Inventory.

Abstract

We aim to assess the validity and reliability of the Arabic language translation of the Summated Xerostomia Inventory (SXI). A cross-sectional, self-administered, electronic Arabic SXI was sent to 79 patients with thyroid nodules (female: n = 34, 57%; male: n = 45, 57%) who visited the Otolaryngology-Head and Neck Surgery clinic at King Abdulaziz University Hospital and King Fahad Medical City between June 2023 and July 2023. Dependability was assessed using Cronbach's alpha coefficients at two distinct instances (first: α = 0.824, second: α = 0.932), which reaffirmed the SXI's reliability and consistency. Legitimacy was ascertained using a test-retest method and correlation analysis between the two measurements. All SXI items displayed a potent positive correlation (between 0.746 and 0.871, p < 0.001), exhibiting remarkable consistency in responses over time. The outcomes of the paired t-tests showed nonsignificant differences for all queries, indicating that the responses were stable over time.
