Acceptance and commitment therapy (ACT) is a psychotherapy based on the philosophy of functional contextualism and behavior analysis. Its aim is to help individuals choose actions aligned with their personal values while accepting distressing and unwanted internal experiences. In consultation-liaison psychiatry (CLP), addressing patients with various psychiatric and physical problems requires collaboration with physicians from other specialties and multidisciplinary teams. With its transdiagnostic characteristics, ACT is effective not only in treating mental disorders but also in managing physical illnesses and intervening in health-compromising behaviors. It is therefore applicable to the diverse conditions encountered in CLP. Furthermore, the functional contextualism underlying ACT facilitates understanding the treatment environment and clarifying shared goals among medical staff, thereby supporting effective interventions by multidisciplinary teams. Although CLP interventions are often constrained by limited time and session frequency, focusing ACT on specific issues enables its practical application within these constraints.
