That fear is not based on fact, according to Darrel Regier, M.D., M.P.H., executive director of the American Psychiatric Institute for Research and Education (APIRE). He testified last month before the Senate HELP committee, chaired by Sen. Edward Kennedy (D-Mass.), a cosponsor of the bill. Regier told senators that mental disorders are real, treatable, and cause high levels of disability. Parity insurance coverage for mental disorders, he said, is affordable, addresses a specific market failure, and can support cost-effective treatment to reduce disability.
