[Personal View] The psychobiological model of disorders of gut–brain interaction: introduction of a novel, integrated, and testable model

Psychogastroenterology encompasses both basic mechanistic research, which identifies psychological mechanisms (eg, fear-learning) that contribute to disorders of gut–brain interaction (DGBIs), and clinical applied research, which evaluates the efficacy of gut–brain behavioural therapies in DGBIs. However, progress in the field is hindered by inadequate communication between these areas, such that mechanistic processes are rarely translated into clinical targets, and interventions are developed with an incomplete understanding of the potential mechanisms by which they work or for whom they work.
