Validation of ‘ItchApp©’ in Poland and in the USA: multicentre validation study of an electronical diary for the assessment of pruritus

Abstract

Although chronic pruritus affects a large part of the population, its reliable assessment remains difficult. Electronical diaries (eDiaries) are often used in multicentre clinical trials. The ItchApp© for Android was developed to assess itch intensity and course and was validated for the German language in 2017.
