Capobianco & Wells (2017) recently wrote a letter to the editor regarding the importance of labelling psychological therapies appropriately, in particular the use of metacognitive therapy (MCT; Wells, 2000) and metacognitive training (MCT+; Moritz, Veckenstedt, Bohn,Köther, Woodward, 2013). The authors raise the importance of not intermixing titles of psychological therapies when the treatments are different as it can lead to confusion for not only researchers but patients as well.For example, it may lead to problems for researchers who decide to conduct a new meta-analysis of metacognitive therapy which may lead to mixing true metacognitive therapy with other approaches that have been given the same label but are not metacognitive therapy at all.
