RESUMO
BACKGROUND: There is very limited evidence on the existence of cancer-related perceived stigma and self-blame among patients with advanced cancer in Asia, and how they are associated with psychosocial outcomes. This study aimed to address the gap in the current literature by (1) assessing perceived stigma, behavioural self-blame and characterological self-blame among Vietnamese patients with advanced cancer, and (2) investigating the associations of perceived stigma and self-blame (behavioural and characterological) with depression, emotional well-being and social well-being. METHODS: This cross-sectional study involved 200 Vietnamese patients with stage IV solid cancer. Depression was measured using the Center for Epidemiologic Studies Depression (CES-D) Scale. Emotional well-being and social well-being were measured with the relevant domains of the Functional Assessment of Cancer Therapy-General (FACT-G) scale. Perceived stigma was assessed using the sense of stigma subscale of Kissane's Shame and Stigma Scale. Behavioural self-blame and characterological self-blame were measured by the patients' answers to the questions on whether their cancer was due to patient's behaviour or character. Multivariable linear regressions were used to investigate the associations while controlling for patient characteristics. RESULTS: Approximately three-fourths (79.0%, n = 158) of the participants reported perceived stigma with an average score of 20.5 ± 18.0 (out of 100). More than half of the participants reported behavioural self-blame (56.3%, n = 112) or characterological self-blame (62.3%, n = 124). Higher perceived stigma was associated with lower emotional well-being (ß = -0.0; p = 0.024). Behavioural self-blame was not significantly associated with depressive symptoms, emotional well-being or social well-being. Patients who reported characterological self-blame reported greater depressive symptoms (ß = 3.0; p = 0.020) and lower emotional well-being (ß = -1.6; p = 0.038). CONCLUSION: Perceived stigma and self-blame were common amongst Vietnamese advanced cancer patients. Perceived stigma was associated with lower emotional well-being while characterological self-blame were associated with greater depressive symptoms and lower emotional well-being. Interventions should address perceived stigma and self-blame among this population.
