Patients with cranial and cervical dystonia (CCD) suffer from visible involuntary facial, head, and neck movements. Therefore, the social appearance of patients with CCD may be seriously affected and self-perceived stigma can be a major source of disability. The present study investigated enacted social stigmatization of patients with CCD. In a pilot study, a semantic differential scale for assessment of stigma was constructed and validated. The final scale contained eight items representing personality traits to be rated on a seven-point scale (-3 negative extreme to 3 positive extreme). Short video sequences (15 seconds) of patients with various types of CCD and age- and sex-matched healthy controls were presented to a sample of 80 biology students (mean age, 19.8 +/- 2.3 years). Immediately after presentation of each video sequence, the students were asked to perform stigma ratings. Significant differences between CCD patients and controls were found on all eight items (P < 0.001 for each). CCD patients were rated as less accountable for their actions, less likeable, less trustworthy, less attractive, less self-confident, more odd and different, more reserved, and more piteous than controls. CCD patients are subject to serious prejudice and enacted stigmatization. There is a need for informing the public about the nature and symptoms of this disorder and a need to support patients to cope with stigmatization.
