The DSM is published by the American Psychiatric Association, but it is used all over the world. This book is referenced directly or indirectly by health insurance companies, government social health care, the medical community, etc. all across the globe. Regardless of which country you live in; it will have an impact on your diagnosis, treatment, and benefits received. The more support signatures we have will equal to the more influence the letter will have .
