Each person’s journey will be different, based on what brought them to therapy, the challenges they are facing, and the difficulties that are present in their social system (including family, friends, job, etc). Some research has shown that the number of sessions may depend on how open to change the client is. Click here for more information. According to the APA (see here), an average of 15-20 sessions need to occur for about 50% of clients to report that they have recovered or improved their symptoms. Other factors may include frequency of sessions (your therapist may encourage you to attend sessions weekly in the beginning and taper off as symptoms improve), the type of therapy used, and the connection between therapist and client.
