The MMPI-2 has a larger and more diverse standardization sample than the original MMPI. This was done to improve the test's psychometric properties and ensure that it could be used across a wider range of populations. While the MMPI-2 includes some new scales and norms, it is largely similar to the original test. It is also considered to be more valid and reliable than the original at discriminating psychiatric patients.
