Addiction specialists know that people recovering from alcoholism benefit from continued support after completing their primary treatment programs. However, not all people have the means or opportunity to receive appropriate continuing care. In a study published in March 2014 in the American Medical Association journal JAMA Psychiatry, researchers from four U.S. institutions assessed the usefulness of a smartphone application called the Addiction Comprehensive Health Enhancement Support System (A-CHESS) as a tool for providing the resources necessary to help recovering alcoholics maintain their sobriety after residential treatment.
