These core assumptions can be represented in the A B C framework that forms the cornerstone of REBT practice. It assumes that activating events and /or inferences about those events (A) engage evaluative beliefs (B) which in turn lead to emotional, psychological and behavioural consequences (C). In therapy, these evaluative beliefs are disputed vigorously (D) and hopefully, replaced with more rational or helpful beliefs which lead to healthier emotions and constructive behaviours (E). In reality A, B and C frequently interact in quite complex ways (Ellis, 1985)
