Abstract

Background: Multiple Sclerosis (MS) is a chronic, autoimmune disease that causes physical and psychological damage and has a highly variable prognosis. It is very important to develop self-care skills apart from symptom treatment that causes individuals to become physically dependent.
Objectives: The study was planned and carried out methodologically to adapt the Multiple Sclerosis Self-Management Scale-Revised (MSSM-R) to Turkish society.
Methods: The study was conducted with individuals with multiple sclerosis who presented to the neurology clinic of a university hospital between July 2019 and May 2020. The validity and reliability of the MSSM-R were tested with 169 participants. Construct validity was examined using confirmatory factor analysis (AMOS), test–retest reliability through paired-sample t-tests and Pearson correlation analysis, and internal consistency using Cronbach’s alpha. Item-level analyses were also performed.
Results: The validity of the MSSM-R was evaluated with language validity, construct validity Confimatory factor analysis (CFA), and content validity. The reliability coefficient of the internal consistency analysis (Cronbach’s Alpha) was found to be very high (.88). Item total correlation was examined, and no items were removed from the scale accordingly. The scale was administered to 30 patients at a two-week interval to evaluate test-retest reliability and time-dependent invariance.
Conclusion: The MSSM-R, which was adapted to Turkish society to evaluate the self-management of individuals with multiple sclerosis, is a valid and reliable tool. The Turkish-adapted MSSM-R is a valid and reliable tool and can be used in both clinical practice and research to support self-management interventions for individuals with multiple sclerosis.
