Translation and validation of a French version of the Xerostomia Inventory

Abstract

Objective This study aimed to assess the transcultural adaptation and psychometric properties of the French‐language version of the Xerostomia Inventory (XI‐Fr). Methods In total, 65 patients aged 65 years or older were recruited from three departments of a single French hospital. Patients had to have a Mini Mental State Examination score of 10 or more and be able to read and write French. The XI‐Fr was administered to all patients after transcultural adaptation, at the start of the study, and again at 7 days after inclusion. We assessed reliability, acceptability, validity, internal consistency and reproducibility of the instrument in its French‐language version. Results The XI‐Fr showed good internal consistency (Cronbach's alpha 0.79) and good reliability (intra‐class correlation 0.83) at 7 days. Convergent validity showed no relation between salivary flow and XI‐Fr score, as with the original instrument. Discriminant validity showed a positive correlation between the XI‐Fr and the GOHAI, but no difference for the MNA or miniGDS scores. Conclusion The XI‐Fr is a valid and reliable measure of xerostomia in French, with psychometric properties comparable to those of the original English‐language version.

Validation of the Korean version of the Summated Xerostomia Inventory among older adults residing in nursing homes

“…The SXI consists of five items and can be used quickly and easily in clinical settings. It is suitable for frail older adults, and its validity and reliability have been accepted by targeting the older population in several countries [11][12][13].…”
