WPDS meaning in General ?

The Woodworth Personal Data Sheet, sometimes known as the Woodworth Psychoneurotic Inventory was a personality test, commonly cited as the first personality test, developed by Robert S. Woodworth during World War I for the United States Army. It was published in 1919 and It was developed to screen recruits for shell shock risk but was not completed in time to be used for this purpose. It instead became widely used in psychological research and led to the development of many other personality tests. It has been described as "the linear ancestor of all subsequent personality inventories, schedules and questionnaires".
