The American Psychopathological Association (APPA) is an organization "devoted to the scientific investigation of disordered human behavior, and its biological and psychosocial substrates." The association’s primary purpose is running an annual conference on specific topics relevant to psychopathology research. Leading investigators from both the U.S. and abroad are invited to present original papers on topics chosen by the president. History Around 1900, William James called for an "American Psychopathological Society". His call was in response to the gap he felt had occurred between normal psychology and more morbid sciences dealing with full-blown insanity. He wrote a proposal for an American Psychopathological Association, and in 1910, the American Psychopathological Association was founded. On May 2, 1910, the American Psychopathological Association was organized at the Willard Hotel in Washington, D.C. Due to the fact that both the American Neurological Association and the American Medico-Psychological Association (now the American Psychiatric Association) were holding annual meetings at the Willard, it was easy for people interested to attend. According to the historical membership lists, there were 42 founding members of APPA. The earliest list is from 1911, which reflects the original members as well as five newly elected members. The proceedings of the meeting were published in the June–July 1910 issue of The Journal of Abnormal Psychology, which was designated the official journal of the APPA. Every year the APPA elects a president-elect, who organizes a future annual meeting and presides over the meeting as president. APPA presidents include well known psychopathology researchers, including Clarence P. Oberndorf, Lee N. Robins, and Joseph Zubin. Annual meeting The primary mission of APPA is to sponsor an annual conference on a specific topic relevant to research in psychopathology. Unlike professional organizations of psychiatrists, psychologists or other health researchers, the APPA annual meeting is explicitly interdisciplinary. Leading investigators from the U.S. and abroad are invited to give original papers on the topic chosen by the president, in consultation with a governing body called the APPA Counsel. In recent years the meetings have been on the boundaries of psychopathology, biomarkers and personalized treatment of psychopathology, and chronic psychopathology and the long-term treatment (or neglect) of persons with chronic disorders. They meetings are traditionally in New York City in the first week of March, and is open to members and nonmembers alike. Membership Members and fellows of APPA are nominated and elected during the annual meeting. To be elected, persons must
