• While metacognitive interventions are gaining attention in the treatment of various mental disorders, a review of the literature showed that the term is often defined poorly and used for a variety of psychotherapeutic approaches that do not necessarily pursue the same goal. We give a summary of three metacognitive interventions which were developed within a sound theoretical framework-metacognitive therapy, metacognitive training, and metacognitively-oriented integrative psychotherapies-and discuss their similarities and distinctive features. We then offer an integrative operational definition of metacognitive interventions as goal-oriented treatments that target metacognitive content, which is characterized by the awareness and understanding of one's own thoughts and feelings as well as the thoughts and feelings of others. They aim to alleviate disorder-specific and individual symptoms by gaining more flexibility in cognitive processing.
