The officer selection system initiated by the command psychiatrist of the Scottish command in 1941 is described: it included a three-part questionnaire--military, personal and social, and interests; an intelligence test (Raven's Progressive Matrices (an officer should be above the 70th percentile)) and a reasoning test; a word association test; and an adaptation of the TAT. The responsibility of the psychologist member of the board was the measurement of the candidate's intelligence and tentative assessment of his personality. Testing time averaged 3.5 hours per candidate. The psychiatrist member of the board interviewed the candidates--all Middle East candidates, but only half of the candidates in England. This interview was aided by the report of the psychologist who indicated personality pointers and "it took a very brave psychiatrist to go against what the psychologist said." The work of the military testing officer who observed the candidates in group discussions, tasks, games, and activities, is further discussed by S. Yeldham in an additional note. In the general discussion following the papers by Gillman and Yeldham, various psychiatrists discussed the possible applications of analogous selection methods to the problem of screening physicians who wish to become psychiatrists.
