Development of the Multiple Sclerosis Resiliency Scale (MSRS).

Objectives: While resilience has been an area of increasing research, there are no measures that are specific to the psychological, social, and physical factors associated with resilience in persons with multiple sclerosis (PwMS). This study aimed to develop the MS Resiliency Scale (MSRS), a multidimensional measure. Items were created based on a review of the literature, with five hypothesized subscales, and then evaluated in a large sample of PwMS. Method: Participants (N = 932) were primarily recruited through the North American Research Committee on MS (NARCOMS) and completed the study electronically. Principal components analysis was utilized to determine the number of factors and whether they aligned with the theorized model. Results: Using an unforced solution with oblique (promax) rotation and Kaiser normalization, and suppressing items with coefficients below 0.4, 25 items were retained in five subscales that accounted for 42.75% of the variance: Emotional and Cognitive Strategies (13 items; α = .92), Physical Activity and Diet (3 items; α = .77), MS Peer Support (2 items; α = .82), Support from Family and Friends (5 items; α = .79), and Spirituality (2 items; α = .91). The total score was negatively correlated with depression, r = −.72, p < .001 and anxiety, r = −.56, p < .001. Implications: The 25-item MSRS assesses several psychological, social, and physical factors associated with resilience in PwMS, and may be a helpful tool in identifying individuals in need of additional assistance or support.
