Background: People with essential tremor (ET) can be subject to stigma, and some adopt avoidance behaviors. Characteristics associated with ET stigma and the relationship between perceived stigma and social dysfunction have not been studied.
Objectives: To discern predictors of perceived stigma and social dysfunction in ET, and to identify potentially treatable psychological factors associated with social dysfunction.
Methods: We surveyed ET patients (n = 158) on recalled stigma incidents and social dysfunction related to tremor, as well as clinical and demographic characteristics including tremor severity, and psychological constructs including anxiety, depression, mindfulness, resilience, and narcissism.
Results: Worse tremor severity (Standardized beta [SB] 1.4, P < 0.001) especially among younger participants (interaction of age and tremor severity SB -0.9, P < 0.001) and presence of vocal tremor (SB 0.7, P = 0.002) predict perceived stigma. 53/157 (33.8%) participants met criteria for social dysfunction, employing maladaptive avoidance strategies. Scores for perceived stigma (Odds Ratio [OR] 1.2, P = 0.002), depression (OR 1.5, P = 0.004) and stigma psychological distress (OR 1.2, P = 0.001) as well as sex (OR 4.3 for females, P = 0.045) predicted social dysfunction.
Conclusions: Depression and stigma psychological distress contribute to social dysfunction related to ET stigma. Treating these psychological factors may mitigate social avoidance behaviors prevalent among susceptible individuals: those who most perceive ET stigma, i.e. relatively younger patients with worse tremor or with vocal tremor, and in particular females who are more prone to social dysfunction than males with the same degree of perceived stigma.
