Perceived epilepsy stigma mediates relationships between personality and social well-being in a diverse epilepsy population

Abstract

IntroductionPerceived epilepsy stigma and reduced social well-being are prevalent sources of distress in people with epilepsy (PWE). Yet, research on patient-level correlates of these difficulties is lacking, especially among underserved groups. Materials and methodsRacially/ethnically diverse adults with intractable seizures (N=60, 62% female; 79% Black, 20% Hispanic/Latino, 8% White) completed validated measures of personality (NEO Five Factor Inventory, NEO-FFI-3), perceived epilepsy stigma (Epilepsy Stigma Scale, ESS), and quality of life (Quality of Life Inventory in Epilepsy, QOLIE-89). Controlling for covariates, ordinary least-squares (OLS) regression evaluated the total, direct, and indirect effects of NEO-FFI-3 neuroticism and extraversion scores on epilepsy-related social well-being (i.e., combination of QOLIE-89 social isolation and work/driving/social function subscales, α=0.87), mediated through perceived stigma. ResultsIn separate models, higher levels of neuroticism (N) and lower levels of extraversion (E) were significantly and independently associated with greater perceived stigma (N path a=0.71, p=0.005; E path a=−1.10, p<0.005). Stigma, in turn, was significantly and independently associated with poorer social well-being (N path b=0.23, p<0.001; E path b=−0.23, p<0.001). Bias-corrected bootstrap confidence intervals (CIs) showed that neuroticism and extraversion were indirectly associated with social well-being through their respective associations with perceived stigma (N path ab=−0.16, 95% CIs [−0.347, −0.044]; E path ab=0.25, 95% CIs [0.076, 0.493]). ConclusionHigher neuroticism and lower extraversion covaried with stigma beliefs, and these may be markers of poor social outcomes in PWE. Mediation models suggest that targeting epilepsy stigma beliefs may be a particularly useful component to incorporate when developing interventions aimed at promoting social well-being in diverse PWE.
