Psychotherapy continues to be bedevilled by ideological schisms with practitioners apparently ignoring alternative conceptualizations and potentially superior interventions. However, I argue here that there is evidence of a rapprochement, both in theory and in practice, between cognitive therapy and psychoanalytic therapy, especially within the domain of personality disorder, which may lead to the development of integrative psychotherapy. Cognitive therapy has begun to encompass an interpersonal approach within its theoretical base. Similarly, psychoanalytic therapy increasingly uses an interpersonal formulation of the process of therapy. The therapeutic alliance is emphasized equally and process research suggests that interventions, when given by experienced practitioners, are not as dissimilar as ‘brand-named’ therapies imply. Continued refinement of process psychotherapy research could lead to true integration of efficacious therapeutic interventions. But translating research findings into practice will necessitate psychotherapists opening themselves up to each others' ideas.
