The impact of visible and invisible symptoms on employment status, work and social functioning in Multiple Sclerosis.

BACKGROUND

Frequently diagnosed in young adulthood, multiple sclerosis (MS) and several MS-related factors can influence patients' unemployment status and negatively affect work productivity and daily functioning.

OBJECTIVE

We examined MS patients' employment status and evaluated clinical features influencing it. Furthermore, we investigated patients' burdens due to visible and invisible MS symptoms through their worsening daily functioning.

METHODS

The study included outpatients affected by MS according to the 2010 McDonald criteria. The co-occurrence of invisible symptoms (fatigue, depression and apathy) was stated using validated, self-administered tools: Fatigue Severity Scale (FSS); Beck Depression Inventory-Second Edition (BDI-II); Apathy Evaluation Scale (AES). Impairment in daily functioning due to MS was assessed using the Work and Social Adjustment Scale (WSAS). Descriptive statistics, hierarchical regression analyses, Pearson's correlation, and the t-test were conducted.

RESULTS

Of the 123 participants, 52 (42.3%) were unemployed. Results showed employment to be positively associated with higher education levels (p 0.01); female gender (p 0.03) and higher disability (p 0.02) showed negative associations with employment. No associations were found between employment and fatigue or clinically relevant depressive and apathetic symptoms. High correlations were found between WSAS score and Expanded Disability Status Scale score (r = 565, p < 0.001), BDI-II score (r = 588, p < 0.001), and FSS score (r = 545, p < 0.001).

CONCLUSION

Our study revealed physical disability's significance in determining MS patients' unemployment. Alternatively, invisible MS symptoms negatively affected principally patients' social lives. Therefore, programs should be designed to improve MS patients' work integration and daily activities.
