How to Convert Raw Scores to T Scores on the MMPI-2
Instructions
-
-
1
Administer the test following all of the guidelines in the MMPI-2 manual.
-
2
Score the test, using the supplied scoring templates for the basic clinical and validity scales. Use the appropriate template for your version of the MMPI-2: The hardcover, softcover and computer administered versions all have different scoring templates. Also use the appropriate template for Scale 5: Men and women test takers require different templates. The scoring process reveals the test taker's raw scores.
-
3
Transfer the raw scores to the profile sheet included in the assessment package. The profile sheet has two sides: one for females and one for males. Use the side appropriate to the gender of the test taker.
-
4
Underline the raw score for the K scale on the profile sheet. The K scale is a validity scale that measures defensiveness. Find this raw score on the K-correction table included in the assessment package. This table indicates what fraction of K you must add to the other raw scores before converting the scores to T scores.
-
5
Indicate the raw score plus the K scale addition on the profile sheet.
-
6
Plot the adjusted scores for each scale on the profile matrix included in the assessment package. Connect all of the values for the clinical scales with a solid line. Then, connect all of the values for the validity scales with a separate solid line. This plot, with the two separate lines, constitutes the test taker's profile.
-
7
Look to the extreme left or the extreme right of the matrix. The T score values appear in both locations.
