Belief change is an important element of much CBT, yet very little consideration has been given to the theories of knowledge, the epistemology, which underlie this process. This article argues that understanding the epistemic basis of the techniques therapists use can help guide their choice of interventions. The empirical evidence for cognitive restructuring is considered, the importance of distancing and decentring noted, and three epistemic styles are identified: the rational-empiricist, pragmatist and ‘constructivist’ approaches. Different schools of CBT emphasise one or more of these. The article describes how these epistemes can be used to make decisions about which cognitive interventions to use, particularly when clients may be sceptical about reality testing because of entrenched beliefs or real-life adversity.
