An individual takes the MMPI-2, and the resulting profile shows a T-score of 85 on the Fb (Back-F) scale, while the F scale T-score is 55. The VRIN and TRIN scales are within normal limits. What is the most appropriate next step in interpretation?

Accepted Answer

Interpret the clinical scales with extreme caution, as the individual may have stopped paying attention in the latter half of the test.
