Using the multiple sclerosis resiliency scale to identify psychological distress in persons with multiple sclerosis

Psychometric validation of the Arabic multiple sclerosis resiliency scale: Uncovering resilience factors in Lebanese MS patients for clinical and research advancements

Background

Multiple sclerosis (MS) is an autoimmune demyelinating disease that involves the central nervous system (CNS). Individuals with Multiple Sclerosis (MS) may experience difficulty adapting to their diagnosis as the unpredictable nature of the disease can be challenging to cope with.

Methods

The purpose of this study is twofold. First, we have culturally adapted and analyzed the Arabic version of the Multiple Sclerosis Resiliency Scale (MSRS) psychometric properties. Second, we aimed to explore resilience in a sample of Lebanese patients with MS in the face of the chronic disease and financial hardship that Lebanon is going through to evaluate their strengths and struggles. The sample consisted of 306 participants aged between 18 and 79 diagnosed with MS for at least one year.

Results

After examining criterion validity, construct validity, internal consistency, and test-retest reliability, the Arabic version of the MSRS exhibited good psychometric properties. The study also revealed that resilience increases with age and lower disability scores. Additionally, individuals with higher resilience levels displayed lower levels of depression. The research revealed that MS patients have high resilience, mainly relying on cognitive and emotional strategies, social support from family and friends, MS peer support, and spirituality.

Conclusion

These findings highlight the importance of emotional coping strategies and social support in building resilience among MS patients.

Resilience, mental health, sleep, and smoking mediate pathways between lifetime stressors and Multiple Sclerosis severity

Intro

Lifetime stressors (e.g., poverty, violence, discrimination) have been linked to Multiple Sclerosis (MS) features; yet mechanistic pathways and relationships with cumulative disease severity remain nebulous. Further, protective factors like resilience, that may attenuate the effects of stressors on outcomes, are seldom evaluated.

Aim

To deconstruct pathways between lifetime stressors and cumulative severity on MS outcomes, accounting for resilience.

Methods

Adults with MS (N=924) participated in an online survey through the National MS Society listserv. Structural Equation Modeling was used to examine the direct and indirect effect of lifetime stressors (count/severity) on MS severity (self-reported disability, relapse burden, fatigue, pain intensity and interference), via resilience, mental health (anxiety and depression), sleep disturbance, and smoking.

Results

The final analytic model had excellent fit (GFI=0.998). Lifetime stressors had a direct relationship with MS severity (β=0.27, p<.001). Resilience, mental health, sleep disturbance, and smoking significantly mediated the relationship between lifetime stressors and MS severity. The total effect of mediation was significant (β=0.45).

Conclusions

This work provides foundational evidence to inform conceptualization of pathways by which stress could influence MS disease burden. Resilience may attenuate effects of stressors, while poor mental health, smoking, and sleep disturbances may exacerbate their impact. Parallel with usual care, these mediators could be targets for early multimodal therapies to improve disease course.

Establishing the Test-Retest Reliability and Minimal Detectable Change of the Multiple Sclerosis Resiliency Scale

BACKGROUND

The Multiple Sclerosis Resiliency Scale (MSRS) was designed to assess factors connected to resilience when facing MS-related challenges. Although the MSRS has demonstrated good internal consistency and construct validity, its test-retest reliability has yet to be established. Identifying the minimal detectable change (MDC) of the scale will also improve its utility as an outcome measure for resilience-based interventions. This study aimed to determine the test-retest reliability and MDC of the MSRS.

METHODS

Participants were 62 persons with MS who completed the MSRS twice, with a mean ± SD of 16.60 ± 3.97 days (range, 14-30 days) between assessments. Test-retest reliability was evaluated using a 2-way, random-effects, single-measurement intraclass correlation coefficient (ICC), with agreement between time 1 and time 2 visualized with a Bland-Altman plot. The MDC was calculated using the standard error of measurement with a 95% CI.

RESULTS

At time 1, the mean ± SD MSRS score was 77.19 ± 11.97 (range, 45.83-97.00); at time 2, the mean ± SD score was 76.38 ± 12.75 (range, 46-98). The MSRS total score had good test-retest reliability (ICC = 0.88), with the subscale ICCs ranging from 0.77 (MS Peer Support) to 0.93 (Spirituality). The MDC for the total score was 11.95.

CONCLUSIONS

These findings suggest that the MSRS has good test-retest reliability and that persons with MS with a difference of 12 points or more between assessments have experienced a reliable change. The results support the utility of the MSRS as a potential outcome measure for MS-related resilience.
