Relationship Between Severity of Multiple Sclerosis and Fear of Falling Mediated by Cognitive and Physical Factors

Background & Aims: Multiple sclerosis (MS) patients are exposed to various health threats, including fear of falling (FOF), which restricts their daily life activities and cause isolationism and lower social participation. The present study aimed to investigate the relationship between the severity of MS and FOF through the mediating role of cognitive and physical factors in patients with MS. Materials and Methods: This was a correlational study based on path analysis. The statistical population consisted of all patients with MS who visited the neurology centers of hospitals in Sari, Iran, ۲۰۰ of whom were selected as the sample using convenience sampling. The research instruments included the Falls Efficacy Scale-International (FES-I), MS Severity Scale, Cognitive Factors Questionnaire, and the MOS ۳۶-item Short-Form Health Survey (SF-۳۶). Results: The results indicated that there was a negative and significant relationship between FOF and cognitive and physical factors and also a positive and significant relationship between FOF and the severity of MS (P < ۰.۰۱). In addition, the results corroborated the negative and significant relationship between the severity of MS and physical factors (P < ۰.۰۱). However, the direct relationship between the severity of MS and cognitive factors were excluded from the model because it was not established. The study findings confirmed the relationship between FOF and the severity of MS mediated by cognitive and physical factors (P < ۰.۰۰۱). Conclusion: According to the results FOF was found to be much higher among patients with higher MS severity. The severity of MS had a positive relationship with FOF in the patients. Moreover, cognitive and physical factors had a mediating role in the relationship between the severity of MS and FOF.
