Assessment of stigma among patients living with Parkinson's disease: an exploratory study

This cross-sectional study aims to assess the levels of stigma among patients with Parkinson's disease (PD) and identify the demographic and clinical factors influencing both internal and external stigma.

A total of 200 patients diagnosed with PD were recruited from Beijing Tiantan Hospital between June 2023 and June 2024 using convenience sampling. Data were collected through face-to-face interviews, including demographic information, disease severity assessed via the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), and stigma levels measured using the 24-item Stigma Scale for Chronic Illness (SSCI). Statistical analyses included t-tests, ANOVA, correlation analysis, and multivariate linear regression.

The average SSCI score among PD patients was 58.74 ± 13.73, with significant variation based on age, gender, educational level, marital status, disease duration, and motor subtype. Patients aged under 60, male, with lower educational attainment, divorced or widowed, and with longer disease duration had higher SSCI scores. MDS-UPDRS Part I-III scores were positively correlated with both internal and external stigma (r = 0.4, 0.5, and 0.5, respectively, p < 0.001). Multivariate linear regression analysis identified MDS-UPDRS scores, age, self-care ability, marital status, disease duration, and motor subtype as independent predictors of stigma.

Stigma in PD is influenced by a combination of demographic and disease-related factors, particularly disease severity. Targeted interventions focusing on reducing motor and non-motor symptoms, as well as addressing social determinants, may help alleviate the stigma experienced by PD patients. These findings underscore the need for comprehensive management strategies that incorporate both clinical treatment and psychosocial support.
