Psychological evaluation and treatment of gastrointestinal motility and functional disorders: Including cognitive behavioral therapy

Supported by the current understanding of the bidirectional relationship between the brain and the gut, psychosocial variables can contribute to the development and course of gastrointestinal (GI) motility and functional disorders. Psychological treatments, including cognitive behavioral therapy (CBT), aim to modify these variables, thereby addressing dysregulation of the gut-brain axis. This chapter will describe the psychological evaluation and treatment of GI motility and functional disorders.
