Introduction: Multiple sclerosis (MS) is a disease that causes different symptoms in each attack and has an individual-specific course. Detailed questioning and recording of MS symptoms is important for developing a management plan for individual-specific symptoms. The present study was planned to evaluate the validity and reliability of the Turkish version of Multiple Sclerosis-Related Symptom Checklist (MS-RS), which has been developed for patients to personally follow-up the symptoms they experience.        


Methods: The study was conducted in the outpatient MS clinic of the Istanbul University Istanbul Faculty of Medicine between January and October 2013 and included a sample group of 148 patients who were aged >18 years, could easily communicate, had a definite diagnosis of MS, and had no other medical problems besides MS. The data were collected using patient information forms, including sociodemographic and MS-RS forms. To assess the linguistic validity, the Likert-type scale with 26 items was first applied to a group of 30 patients. Confirmatory factor analysis was used to test the construct validity. Furthermore, the correlation of the scale with the Expanded Disability Status Scale (EDSS), Hospital Anxiety and Depression Scale (HADS), Mini-Mental Status Evaluation (MMSE) scale, and Multiple Sclerosis Quality of Life Scale-54 (MSQL-54) was evaluated.


Results: The scale comprised five factors with factor loading values between 0.39 and 0.86. The item-total correlation coefficients revealed values of 0.27–0.88. The Cronbachs alpha reliability coefficient for the whole scale was determined to be 0.89 and for the subscales to be 0.60–0.85. The test–retest analysis revealed no difference between the scale and its subscales in terms of invariance with time (p>0.05). Moreover, MS-RS was significantly correlated with EDSS, HADS, MMSE, and MSQL-54.


Conclusion: The Turkish version of MS-RS is a valid and reliable scale that can be used in the Turkish population.
