The progress note should include who was present, what the client discussed, the therapist's interventions, and the agreed upon future plan. It functions as a legal, clinical, and insurance document that the patient can access. The SOAP format is commonly used, with S (Subjective) including the client's perspective, O (Objective) the therapist's observations, A (Assessment) the therapist's interpretation, and P (Plan) future interventions and the prognosis. A sample note is provided that follows this format and documents a session where the client expressed anger issues and the therapist's interpretation and continued treatment plan.
