Part IV - Multidimensional Characteristics of Orthorexia Nervosa

Summary

Part IV emphasises the significance of psychological and nutritional characteristics of orthorexia nervosa to gain better insight into the construct of orthorexia nervosa. It focuses on the relationship of orthorexia nervosa with self-esteem, personality traits, eating behaviours (disordered eating behaviours, food addiction, mindful eating), health-related beliefs and behaviours (physical activity), body image, emotion regulation and dietary patterns. It also presents a potential social risk factor of orthorexia nervosa - social media use. A summation of the highlights is included at the end of this chapter. The commentary of the invited international expert (Professor Marle Alvarenga, University of Sao Paulo) provides valuable insights on orthorexia nervosa.
