abstract: 'The Multiple Sclerosis Work Difficulties Questionnaire-23 (MSWDQ-23) is

  a self-report instrument developed to assess barriers faced by People

  with Multiple Sclerosis (PwMS) in the workplace. The aim of this study

  was to explore the psychometric properties of the Greek version of the

  MSWDQ-23. The study sample consisted of 196 PwMS, all currently working

  in part- or full-time jobs. Participants underwent clinical examination

  and cognitive screening with the Brief International Cognitive

  Assessment for Multiple Sclerosis (BICAMS) and completed self-report

  measures of fatigue, psychological functioning, and quality of life,

  along with the MSWDQ-23 questionnaire. Confirmatory Factor Analysis

  (CFA) was performed, and goodness-of-fit measures were used to evaluate

  construct validity. Convergent validity was checked by correlating

  MSWDQ-23 scores with study measures. Cronbach''s alpha value was produced

  to assess internal consistency. CFA yielded a model with a fair fit

  confirming the three-factor structure of the instrument. Higher work

  difficulties were associated with higher Expanded Disability Status

  Scale (EDSS) scores, poorer cognitive function, more fatigue, stress,

  anxiety, and depression, and poorer health status, supporting the

  convergent validity of MSWDQ-23. Internal consistency (Cronbach''s alpha

  = 0.94) and test-retest reliability (ICC = 0.996, 95\%, CI =

  0.990-0.998) were excellent. The Greek MSWDQ-23 can be considered a

  valid patient-reported outcome measure and can be used in interventions

  aiming to improve the vocational status of PwMS.'
