Unified psychotherapy is a term that was coined by David Allen to describe a model of treatment that he developed and has manualized. Many people have asked what unified psychotherapy is and how it is different from integrative therapy or other forms of therapy. Unified psychotherapy is a conceptual system that honors the meta-framework in which all domains of human functioning are expressed from the micro-level to the macro-level. There are different ways to divide any complex system and the divisions are an artifice as any complex system is inter-related in ways that are not always evident. With regards to psychotherapy unification, it requires that the psychotherapist be cognizant of techniques/methods, relationship principles, and patient-therapist factors, as well as ecological effects. Unified psychotherapy also requires some knowledge of not only the meta-framework in which all human behavior and change occurs and operates but necessitates some knowledge of how the specific component subsystems operate. For example, in previous blogs I discussed the attachment system which is a vital domain of human relationships and neurodevelopment. A knowledge of this sub-system is a requirement for understanding how interpersonal relationships operate and how various attachment systems suggest different techniques, methods, and relational emphasis. One of our goals with UPP and psychotherapedia is to catalogue the techniques using a basic system of classification and in this case we are using four levels. Eventually, when we have a sufficiently populated database we can begin to look at clinical algorythms which will allow us to offer some suggestions about how to sequence methods and incorporate various techniques into the treatment process. This type of sequencing also needs to include modalities and formats since they are important components of treatment. Clarkin and Frances called this type of planning differential therapeutics and with an expanding database we may come closer to offering some useful guidelines for clinicians and some interesting projects for researchers.
