Psychometric properties of the ORTO-R in a community-based sample of women and men from Poland

Abstract

Plain English Summary Over the past two decades, orthorexia nervosa (ON) has been increasingly investigated. Recently, a new revision version of the ORTO-15, namely ORTO-R, was used. We attempted in this paper to evaluate the psychometric properties of the Polish version of the ORTO-R. The Polish version of the ORTO-R is valid and internally consistent method to investigate ON and could be used in research and practices.
