Abstract

Evidence-based dermatology has necessitated the development of rating scales that measure multidimensional and abstract constructs, such as quality of life. This article discusses some basic psychometric concepts, such as reliability, validity, standardization, and measurement precision, which need to be considered when choosing a clinical rating instrument. Also discussed is the impact of these parameters on increasing the statistical power of a clinical trial.

[In memory of our Jewish colleagues who were murdered or committed suicide during the National Socialist Era].

With this article, we commemorate our Jewish colleagues who were murdered or committed suicide during the National Socialist Era in 1933-1945. Additionally, this article should provide an impulse to create a worthy memorial place. We thereby propose to put up commemorative plaques, e.g. in front of the administrative office of the German Dermatologic Society. Fifty-six Jewish dermatologists were killed in concentration camps in the National Socialist Era; 23 died in Theresienstadt, 19 in Auschwitz, and 14 in other concentration or extermination camps. Thirteen Jewish dermatologists committed suicide.
