• Analysis of research practices concerning administration, sample description, validity assessment, score analysis, and result reporting.
• Identification of key areas of debate in MMPI-2 research.

Main Results:

• The review identified specific areas where MMPI-2 research practices could be improved.
• Guidelines were developed for appropriate MMPI-2 test administration and interpretation.
• Key research debates, including codetype comparability and scale validity, were highlighted.

Conclusions:
