Objective:
The 25-item Multiple Sclerosis Resiliency Scale (MSRS) is a self-report measure that assesses MS-related challenges with five subscales: 1) Emotional and Cognitive Strategies, 2) Physical Activity and Diet, 3) MS Peer Support, 4) Support from Family and Friends, and 5) Spirituality. The MSRS has been validated in the adult MS population but not in older adults with MS (OAwMS). Therefore, the objective of the current study was to determine the reliability and validity of the MSRS in OAwMS aged 60 years and older.
Participants and Methods:
Participants were community-dwelling OAwMS (n = 96, age = 64.60 ± 4.21 years, 67.7% female) enrolled in an ongoing cohort study and tested between September 2019 and July 2023. In this study, demographic variables, MS characteristics (MS disease duration, MS subtype, and Patient Determined Disease Steps; PDDS), MSRS, 9-item Resilience Scale (Siu et al., 2009), 12-Item Short Form Survey (SF-12; self-reported outcome measure assessing the impact of health on an individual's everyday life), Medical Outcomes Study Social Support Survey (MOS-SS), Geriatric Depression Scale (GDS), Geriatric Anxiety Inventory (GAI), oral Symbol Digit Modality Test (SDMT), and timed 25-foot walk test (T25FW) data was utilized. All bivariate correlations within MSRS total and subscale scores were analyzed at α = .05 level.
Results:
The MSRS exhibited good to excellent internal consistency total (Cronbach’s α = .876) and within subscales (α =.706 to .917). The MSRS and Resilience Scale total scores were significantly correlated in the expected direction (r = .377, p < .001), and in subscales 1 (r = .416, p <.001) and 2 (r = .204, p = .047). Convergent validity was established via significant correlations (p<.05) between the MSRS total score and several outcome measures (Resilience Scale, SF-12, MOS-SS, GDS, GAI, and PDDS). Only subscale 4 of MSRS was shown to be significantly correlated with SDMT performance (r = .277, p = .006). Only subscales 1 (r = -.203, p = .048) and 3 (r = .250, p = .015) of the MSRS significantly correlated with T25FW gait speed.
Conclusions:
The MSRS displays good to excellent internal consistency, as well as significant construct and convergent validity, as determined via correlations with multiple outcome measures, among OAwMS. Correlations between specific MSRS subscales and cognitive and motor function support the multi-dimensional structure of psychological resilience.
