Reappraisal strategies such as ‘thought challenging’ and ‘cost-benefits analysis’ are a hallmark of cognitive therapy, but sometimes fail to bring about lasting changes in the cognitive-affective structures underlying psychopathology. Modern theories of information processing suggest that experiential, action-based interventions such as chairwork may be a more efficacious route to cognitive modification. Based upon this hypothesis, a ‘dialogical’ approach to cognitive therapy is presented, which aims to bring about change through evocative, here-and-now interactions with parts of the self (self-to-self dialogues) and other individuals (self-to-other dialogues). Implementation principles and facilitation skills which guide this approach are outlined. To illustrate how dialogical interventions are utilized in clinical practice, chair-based strategies for socializing clients to the cognitive behavioural model, restructuring cognitions, facilitating emotional processing, resolving ambivalence, addressing distressing memories, building character strengths, and overcoming therapeutic impasses are described.
