Woodworth Psychoneurotic Inventory

Woodworth Psychoneurotic Inventory

The Woodworth Psychoneurotic Inventory (WPI)—also called the Woodworth Personal Data Sheet or Woodworth Psychopathic Questionnaire—is often cited as a forerunner of modern personality inventories. Psychologist Robert S. Woodworth developed it during World War I to screen U.S. Army recruits.

Origins and influence on psychological testing

The sheet was meant to gauge emotional stability and screen out unstable recruits, but by the time it appeared in 1919, World War I had ended. It still spread widely, was used in clinical research, and remained popular through the 1920s and into the 1930s.

That early use helped shape later assessment practice, and follow-up studies drew on WPI-style items and scoring ideas. Many later inventories owe something to the approach Woodworth pioneered.

Today's scores should not be read against century-old norms in any literal way—samples, wording, and reporting norms all differ, so averages are not directly comparable. The WPI is now mainly of historical interest alongside more current instruments.
