Abstract
Relapsing-remitting multiple sclerosis is a debilitating neurological disease accompanied with adverse consequences for quality of life. The purpose of this study was to investigate the role of relapsing-remitting multiple sclerosis on psychological, disease-related, socioeconomic, and demographic determinants of health-related quality of life of patients. In this cross-sectional descriptive study, 193 patients with relapsing-remitting multiple sclerosis were selected by compliance sampling method among the patients who attended the Iranian Multiple Sclerosis Association in Tehran from March 2014 to July 2014; and they completed the Multiple Sclerosis Quality of Life Questionnaire, the Depression Anxiety and Stress Scales, and the Socio-demographical Questionnaire. Then, a hierarchical multiple regression analysis with the stepwise method is used for data analysis by the PASW-18. According to the findings, in model 1, low socioeconomic status (SES) had a negative coefficient (beta=-0.30, p<0.01), and treatment history had a positive coefficient (beta=0.22, p<0.01). In model 2, while all variables of model 1 were controlled, depression had a negative coefficient (beta=-0.26, p<0.05), while disorder severity of multiple sclerosis had positive coefficients in lower level (beta=0.35, p<0.001), moderate level (beta=0.23, p<0.01), and severe level (beta=0.22, p<0.01). Other studied variables in model 1, and stress and anxiety in model 2 were not predicted in terms of the quality of life (p>0.05). Unfavorable SES, lack of effective treatment history, higher depression, and signs and symptoms severity of multiple sclerosis significantly predict decreased health-related quality of life in patients with relapsing-remitting multiple sclerosis. Thus, it is consequential to emphasize the value of tailored intervention for attending to these factors in the treatment and rehabilitation agendas for improvement of health-related quality of life in relapsing-remitting multiple sclerosis.
