A structured session means that there is an order and organization to the therapy session. Here is a brief overview of the five basic components.
Check in. This is a quick update on what has happened since the previous session and includes a bridge to that session.
Set the agenda. You and your therapist decide together which problems to focus on in the current session. Homework from the previous session can be reviewed during the check-in or as part of the agenda-setting process.
Work the agenda. This involves addressing the identified problems on the agenda.
Homework. You and your therapist collaborate to develop homework for the following session.
Review. At the end of the session you briefly review with your therapist what was covered in the current session and give feedback.
