Implications of these results and limitations of these findings are discussed. Overall, our findings reflect the internal structure comparability of MMPI- 2-RF scale scores generated from MMPI- 2 and MMPI- 2-RF booklets. Finally, MMPI- 2-RF intercorrelations produced from the two forms yielded mostly small and a few medium differences, indicating that discriminant validity and test structure are maintained. Cronbach's alpha and standard errors of measurement were approximately equal between the booklets for all MMPI- 2-RF scales. Statistically significant small differences were observed on the revised Variable Response Inconsistency (VRIN-r) and True Response Inconsistency (TRIN-r) scales. Independent t tests showed no statistically significant differences between MMPI- 2-RF scores generated with the MMPI- 2 and MMPI- 2-RF booklets on the test's substantive scales. Individuals in the final sample who completed the MMPI- 2-RF did not statistically differ on demographics or referral question from those who were administered the MMPI- 2 booklet. No statistically significant differences in MMPI- 2-RF invalidity rates were observed between the two forms.

After exclusion of invalid protocols, the final sample consisted of 96 defendants who were administered the MMPI- 2-RF booklet and 83 who completed the MMPI- 2. We investigated the internal structure comparability of Minnesota Multiphasic Personality Inventory- 2-Restructured Form ( MMPI- 2-RF) scores derived from the MMPI- 2 and MMPI- 2-RF booklets in a sample of 320 criminal defendants (229 males and 54 females).

(PsycINFO Database Record (c) 2017 APA, all rights reserved). The MMPI- 2-RF overreporting validity scales proved to be modestly better predictors of suspected psychopathology malingering-compared with the MMPI- 2 overreporting scales-in dimensional predictive models and categorical classification accuracy analyses. Results provide support for the capacity of both the MMPI- 2 and the MMPI- 2-RF overreporting validity scales to predict suspected malingering of psychopathology.

The current study expands on past research examining the comparative capacity of the Minnesota Multiphasic Personality Inventory- 2 ( MMPI- 2 Butcher et al., 2001) and MMPI- 2 Restructured Form ( MMPI- 2-RF Ben-Porath & Tellegen, 2008/2011) overreporting validity scales to detect suspected malingering, as assessed by the Miller Forensic Assessment of Symptoms Test (M-FAST Miller, 2001), in a sample of public insurance disability claimants (N = 742) who were considered to have potential incentives to malinger. The comparative capacity of the Minnesota Multiphasic Personality Inventory- 2 ( MMPI- 2) and MMPI- 2 Restructured Form ( MMPI- 2-RF) validity scales to detect suspected malingering in a disability claimant sample.Ĭhmielewski, Michael Zhu, Jiani Burchett, Danielle Bury, Alison S Bagby, R Michael
