Comparing MMPI and MMPI-2 Profiles: Replication and Integration

Abstract

Respondents in two settings, a Veterans Administration mental hygiene clinic (n = 94) and a university counseling center (n = 73), completed the test items from the MMPI and MMPI-2 in a single administration, allowing for between-form comparisons that were minimally affected by temporal instability. Concordance rates for high-point codes were 54% and 60%, respectively. Concordance rates for two-point profile codes, regardless of elevation, were 53% and 60%, respectively. Among nonconcordant cases, the proportions of cases with the same high point were 49% and 59%, respectively. In these two samples, 37% and 23%, respectively, of the cases had elevated profiles that were "well-defined." Among these well-defined profiles, concordance rates for high-point codes were 60% and 94%, respectively. These findings are discussed in relation to previous studies of profile concordance between the MMPI and MMPI-2. Implications for clinical practice are suggested.
