Several studies have shown that healthcare clowning has a strong positive effect on pediatric patients in general, but there is limited research into its impact on those with psychological disorders. RED NOSES Clowndoctors Austria – an organization with decades of experience in healthcare clowning – is addressing this issue through a collaboration with the Department of Clinical and Health Psychology at the University of Vienna. A joint study is currently being conducted in several psychiatric in-patient wards across Austria, using salivary stress biomarkers to assess whether clown visits are really benefitting patients.
