This guide outlines a general case formulation model that is integrative, takes an evidence-based approach, and is meant to adapt to any theory of psychotherapy or treatment manual. It describes the context for the model, including the definition of case formulation, its benefits and goals, its history, and contemporary influences; the use of sound reasoning; culturally responsive formulation; the context of the evidence-based integrative approach to psychotherapy, the four basic components of the model, how and what type of information to gather, and basic principles for applying a formulation to treatment; and the steps of the model (creating a problem list, creating a diagnosis, developing an explanatory hypothesis for why the client is having problems, and treatment planning), as well as criteria for evaluating the quality of a case formulation and their application.
