Purpose: The current study aimed to evaluate the psychometric properties of the Dutch version of the Multiple Sclerosis Work Difficulties Questionnaire-23 (MSWDQ-23). Methods: Two hundred and thirty-nine employed persons with multiple sclerosis (MS) and 59 healthy controls completed the MSWDQ-23. To verify the factor structure, a confirmatory factor analysis was conducted. To assess construct validity, the MSWDQ-23 scores were correlated to measures of physical disability, fatigue, cognitive and neuropsychiatric problems, depression, health-related quality of life, and work-related variables. MSWDQ-23 scores were compared within different age groups, gender, education levels, and job types. Predictive validity was assessed using a logistic regression analysis to predict a deterioration in employment status after one year based on MSWDQ-23 scores. Results: The internal consistency of the MSWDQ-23 was acceptable (alpha = 0.913, 95% CI = 0.897-0.928) and the results indicated a fair fit. The MSWDQ-23 showed acceptable construct validity, confirming 94% of the hypotheses. The total scale and the psychological/cognitive subscale were able to predict a deterioration in employment status after one year (chi(2)(1)=18.164, p <0.001). Conclusions: The Dutch version of the MSWDQ-23 is a valid and internally consistent instrument to measure self-reported work difficulties in persons with MS.
