The role of stigma and depression in the reduced adherence among young breast cancer patients in Hungary.

Background: The main aim of our study was to investigate the role of depression, stigmatization, body shame and self-compassion in the adherence of young Hungarian breast cancer patients aged between 18 and 45 years.

Methods: In a cross-sectional online survey, data were collected from 99 young breast cancer patients (BC). Participants completed self-report questionnaires on socio-demographic and cancer-specific parameters as well as psychological factors (adherence: 12-item Medication Adherence Scale; depression: Hospital Anxiety and Depression Scale; stigmatization: Stigma Scale for Chronic Illnesses; body shame: Experience of Shame Scale; self-compassion: Self-Compassion Scale). We tested the predictors and mediators of adherence using hierarchical regression, mediation and moderation analysis among BC patients.

Results: We found that adherence was significantly associated with body shame and stigmatization in our BC sample. In addition, stigmatization alone was a significant predictor of lower adherence. Finally, in mediation models, where body shame was a mediator, we found a significant direct effect between stigma and adherence, in other words body shame had a significant mediating effect between these variables. According to our moderation analysis, self-compassion as a significant moderator acts as a protective factor in the linear relationship between stigma and lower adherence.

Conclusions: Our results highlight the importance of stigma and body shame in the development of adherence in oncological care among young Hungarian BC patients aged between 18 and 45 years. Assessment of stigma, body shame, self-compassion, and the improvement of the availability of evidence-based psychological interventions may increase the adherence of young Hungarian BC patients, leading to more favourable rates of survival.
