Validation and Polish Adaptation of the Authorized Bratman Orthorexia Self-Test (ABOST): Comparison of Dichotomous and Continuous Likert-Type Response Scales

摘要

Although research on orthorexia nervosa (ON) has developed in recent years, there exists a continuous need to develop valid tools to assess ON risk, according to strict diagnostic criteria. The present study aims to conduct Polish adaptation and validation of the Authorized Bratman Orthorexia Self-Test (ABOST), through a comparison of dichotomous and continuous Likert response scales.
