Effects of full-body mirror exposure on eating pathology, body image and emotional states: Comparison between positive and negative verbalization.

Mirror exposure (ME) is an effective technique to improve body image. However, evidence on the underlying mechanisms and the optimal verbalization instruction during ME is lacking. Therefore, this experimental study analyzed mechanisms of ME and therapeutic outcomes by comparing positive (PV) and ne...
