Through the establishment of a broad program by the War Shipping Administration, an attempt has been made to apply to the

personnel of an entire industry the skills, techniques, and experiences of the psychiatric and psychological professions. It is believed that the Psychobiological Service for the wartime United States Merchant Marine is unique in that it has reached practically every seagoing man in the industry. The major tasks are to screen out the many psychopathological and unsuitable individuals who are attracted to this type of employment, even though totally unsuited for it, and to assist in the adequate preparation, orientation, and training of every new man accepted into the industry. The development of the program, the experiences, and techniques are described in twenty-six chapters.
