The first personality inventory ever, the Woodworth Personal Data Sheet, was developed during World War I and published in its final form after the war (Woodworth, 1920). Its purpose was to identify military recruits likely to break down in combat. The final form of the Woodworth contained 116 questions to which the individual responded "yes or "no." The items were selected from lists of known symptoms of emotional disorders and from the questions asked by psychiatrists in their screening interviews. In effect, the scale was a paper-and-pencil psychiatric interview. The Woodworth consisted of questions similar to these: "Do you drink a fifth of whiskey a day?" "Do you wet the bed at night?" you frequently daydream?" "Do you usually feel in good health? Do you usually sleep soundly at night?" The Woodworth yielded a single score, providing a global measure of functioning. Only those recruits who rescore, ported many symptoms received an interview. In this way, the military could concentrate its efforts on the most likely candidates for rejection.
