Cognitive Emotional Regulation (CER) therapy was not a widely known or established therapeutic approach. It is possible that developments or advancements have occurred in the field of therapy since then, but I cannot provide real-time information.
It's important to note that therapy approaches and techniques are continually evolving as research and clinical experience inform new practices. If you are interested in learning about the current state of CER therapy, I recommend conducting a search for recent articles, studies, or professional opinions on the subject.
Additionally, it's always a good idea to consult with mental health professionals or experts in the field for the most up-to-date and accurate information on specific therapeutic approaches and their effectiveness. They can provide you with insights into the current state of CER therapy and whether it might be a suitable option for your needs.
