There is no set length for REBT therapy. It all depends on the patient’s problem, situation, progress, and ability to learn. Typically REBT is a short-term process that might take 12-15 sessions. This is an average count. Depending on the factors, the number of sessions may vary. Each session can be of 40 to 60 minutes. The main goal of REBT is to identify irrational beliefs, challenge those and replace those. An important part of this process is psychoeducation, which means teaching the patients how to continue the process. Once the patient learns to treat himself/herself, the sessions are over because the patient has to continue the practice for her whole life. Here, the therapist has nothing else to do. So, when the question is about the time REBT takes to solve a problem, there is not any definite answer. But we can make an estimation that it takes around 12-15 sessions. Typically, the therapists talk about how many sessions you’ll need after conducting 1-2 sessions. In these primary sessions, they check the patient’s ability to learn and accept, the current situation, and many other things which let them make a prediction about the number of sessions.
