Testing Case Formulation Hypotheses in Psychotherapy: Two Case Examples Original Research Article

We describe two cases that illustrate and demonstrate the effectiveness of a case formulation–driven approach to psychotherapy in which the therapist, in collaboration with the patient, develops a hypothesis (formulation) about the psychological mechanisms that cause and maintain the patient’s difficulties, uses the formulation to guide intervention, and collects data to test the formulation and evaluate the effectiveness of the intervention plan. As shown by the cases reported here, a key strength of this collaborative empirical process is that it enables the patient and therapist to quickly determine when a treatment is failing and take action to rescue it.
