Quizplus · Accepted Answer

The MMPI was initially constructed through an empirical approach in which hundreds of true/false items were given to clinical groups and non-clinical groups. The items that differentiated between the groups were retained, regardless of whether they seemed theoretically relevant. The test items were then refined over several rounds of testing until the final version of the test (the MMPI-2) was developed in 1989. Therefore, the items were selected through trial and error rather than theory.
