Measuring professional stigma towards patients with a forensic mental health status: protocol for a Delphi consensus study on the design of a questionnaire.

Introduction: Negative attitudes towards individuals with a mental illness and/or criminal background are widely studied, but empirical interest in the attitudes towards patients with a forensic mental health status is lacking. Negative attitudes among mental healthcare (MHC) professionals can have a significant impact on treatment outcomes and hence, affect patients' rehabilitation. This study will elaborate an instrument to assess stigmatising attitudes among community MHC professionals towards patients with a forensic mental health status.
