Metacognition, affect regulation and symptom expression: a transdiagnostic perspective.

The editors of this special section commissioned this commentary to bring together some of the conceptual, empirical and measurement issues arising from this series of articles. This commentary explores metacognition in relation to its neurobiology, and diverse syndromes and clinical phenotypes, including schizophrenia, alexithymia, and personality disorders, as well as its relation to assessment and prospects for the further delineation of mechanisms of change in psychological therapy.
