Abstract

Health-related quality of life (HRQoL) is the prioritized measure in multiple sclerosis (MS) patients. The short quality of life scale (SQoL) developed by Devy et al. (2013) is an MS-specific and abbreviated scale with ten items suitable for routine medical care settings. The current study reported the cross-cultural validation of the scale in the Persian language. A total of 455 convenient MS patients with a mean age of 38.39 (9.28) ranged from 18 to 64 filled out the primary measure and the validating measures, including hospital anxiety and depression scale, visual analogue scale – quality of life, and a single index of the number of past-year MS relapse. The confirmatory factor analysis on original structure indicated an acceptable model fit. However, a modestly modified structure composing of physical-functional dimension (items #1–3), mental dimension (items #5–8), and pain & energy dimension (items 4 & 9,10) was also exposed with a sound fit and a meaningful structure. The overall internal consistency reliability was sound (0.88), and the concurrent validity was confirmed. The Persian short quality of life scale (P-SQoL) is the first translated and validated version of the scale, surfacing significant implications. Further cross-cultural investigations are recommended to re-examine current findings. The classic and recent suggestions concerning the close interplay between the immunity system and the psychological system and the implications based on Iran's context are discussed. © 2021
