Introduction: Internalized stigma constitutes a major concern in mental health illness. It has numerous repercussions on patients, including poor self-esteem, higher illness severity, poor adherence to care and reduced global functioning. The goal of this study was to compare internalized stigma between three diagnoses frequently seen in psychiatric practice: Borderline personality disorder (BPD), Attention deficit-hyperactivity disorder (ADHD) and Bipolar disorder (BD).

Methods: A total of 244 French-speaking patients were recruited in a specialized psychiatric center at University Hospitals of Geneva, Switzerland. 39 patients had a diagnosis of BPD, 136 had ADHD and 69 had BD. Every subjects completed the Internalized Stigma of Mental Illness (ISMI) scale, which is the most widely used scale employed to measure of internalized stigma. One way ANOVA analysis with adjustment on age and gender was done to compare the three groups (BPD, ADHD, BD).

Results: Participants with BPD reported higher ISMI score than subjects with ADHD and BD. BD experienced more internalized-stigma than ADHD. Higher ISMI score was also associated with higher severity of the respective disorder, poorer quality of life and unemployment.

Limitations: Limitations of this research include the small sample, especially in BPD group. A disequilibrium between male and female subjects can also impact our results. Observational nature of our study mean that we can only make correlation between variables and not infer causality. Finally, other confounding factors not taken into account in this study may have had influence on stigma.

Conclusions: Our findings are coherent with recent literature on BPD reporting high level of distress and of stigmatization. This has serious consequences on provided care and need to be address by mental health professionals to assure the optimal service to this population.
