To meet this aim, Metacognitive Training for Depression (D-MCT) has been developed as a low-threshold, highly standardized and yet easy to administer group concept for the treatment of depression. It is conceptualized as a variant of CBT that adopts a metacognitive perspective focusing on the modification of cognitive biases, and is compatible with a general CBT treatment approach. Use of standardized presentations reduces time needed for preparation and administration of the training; moreover, this "packaging" increases the accessibility of D-MCT to a wide range of health care providers, and encourages standardization across therapists. The training seeks to enable group members to recognize and correct the often automatic and unconscious thought patterns that accompany depression. To this end, it attempts to challenge cognitive biases through the use of creative and engaging exercises supported by a multimedia presentation (e.g., insight based on "aha" effects rather than psychoeducation) and to encourage patients to take a metacognitive perspective ("think about one's thinking"). The training is highly flexible with regard to depth and intensity. Patients do not need to (but may) discuss their own problems, and can still experience how cognitive biases work and influence one's mood in a playful atmosphere. The training is conceptualized as an open group: New patients can join the group in every session. Thus, the threshold for administration of and participation in this intervention is low.
