Stigma in Multiple Sclerosis: The Important Role of Sense of Coherence and Its Relation to Quality of Life.

Background: Anticipated and experienced stigma constitute important issues for patients with multiple sclerosis receiving adequate healthcare. Stigma is likely to be associated with lower quality of life in patients with multiple sclerosis, but the underlying mechanisms and contributing factors are unclear.

Methods: We conducted a cross-sectional survey among N = 101 patients with a diagnosis of multiple sclerosis in a German outpatient department. Patients completed questionnaires on enacted and self-stigma (SSCI-8), sense of coherence (SOC-L9) and quality of life (MusiQol). Age, sex, disease duration, disability or extent of limitations (EDSS), cognition (SDMT), depression (BDI-II) and fatigue (FSMC) were used as covariates in linear regression and mediation models.

Results: 57.3% of patients with MS reported having experienced stigmatization due to MS at least once. Fatigue (b = -0.199, p < 0.001), enacted stigmatization experience (b = -0.627, p = 0.010) and sense of coherence (b = 0.654, p < 0.001) were significant predictors for quality of life. The mediation analysis showed a partial mediation of the association between enacted stigma and quality of life by patients' sense of coherence (direct effect: b = -1.042, t = -4.021, p < 0.001; indirect effect: b = -0.773, CI = -1.351--0.339. The association of self-stigma with quality of life was fully mediated by sense of coherence (b = -1.579, CI = -2.954--0.669).

Conclusion: Patients with multiple sclerosis are affected by stigma, which is associated with lower quality of life. Sense of coherence is a potentially important mediator of stigma and represents a promising target to refine existing stigma interventions and improve the quality of life in these patients.
