This study is to assess the relationship between CI, disgust and empathy in medical staff treating patients with scabies, to differentiate the impact of visual and verbal stimuli contributing to CI and to assess information about CI, disgust and empathy in a family infested with scabies.
Itch is the commonest skin-related symptom, defined as a bodily sensation provoking the urge to scratch. The induction of itch and scratching by mere (audio-) visual stimuli such as pictures of insects on skin or video clips showing individuals scratching themselves, indicates that itch can be perceived in the absence of a pruritogenic somatosensory stimulus. This phenomenon is referred to as "contagious itch" (CI). CI may play a special role in the content of scabies both for the affected patients as well as the treating staff: It is a very common phenomenon that family members who are not infested by scabies themselves experience itch when watching their infested relatives scratching. The same is very frequently expressed by health care professionals being confronted with scabies patients. Two further important factors may be involved in the context of CI: disgust and empathy. Empathy is defined as a psychological concept that enables individuals to understand and share emotions of others. Disgust is an emotional response of revulsion to potentially contagious and/or harmful objects or subjects. This study is to assess the relationship between CI, disgust and empathy in medical staff treating patients with scabies, to differentiate the impact of visual and verbal stimuli contributing to CI and to assess information about CI, disgust and empathy in a family infested with scabies.

| Empathy scored by Saarbrucken Personality Questionnaire (SPQ) | The Saarbrucken personality questionnaire SPQ is the German version of the Interpersonality Reactivity Index (IRI) used for the measurement of empathy.
