A number of researchers have called for the establishment of a Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) correlate literature that is based directly on investigations of the revised MMPI. The purpose of this study was to examine clinical correlates found for 9 commonly occurring 2-point codes, each of which contained a minimum of 20 patients, and for 82 profiles that were within-normal-limit (WNL) in a sample of 289 female and 308 male psychiatric inpatients. Major findings indicated that descriptors identified for MMPI-2 based codes were generally similar to the established literature for corresponding codes derived from the original MMPI (Hathaway & McKinley, 1967). In addition, correlates identified for the WNL profile suggest that these patients are less likely to exhibit more chronic symptomatology and to have psychological histories marked by less severe psychological disturbance than other inpatients. Overall, the results of this study represent an initial step in the creation of an MMPI-2 correlate literature.

The current study replicated and expanded previous investigations that focused on the incremental contribution of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) content scales. The MMPI-2 and the Symptom Checklist-90-Revised (SCL-90-R) were administered to 597 adult psychiatric patients (289 females, 308 males) receiving inpatient treatment. In addition, clinical psychologists provided ratings on each of these patients with the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment Scale (GAS). A series of hierarchical stepwise multiple regression analyses were conducted with MMPI-2 basic and content scales as the independent variables and SCL-90-R, BPRS, and GAS variables as the dependent criteria. Similar to Findings by Ben-Porath, McCully, and Almagor, MMPI-2 content scales were shown to add incrementally to the prediction of variance on self-report measures; the current study also revealed significant relationships to clinician-rater criteria. Implications of the present findings for test interpretation procedures and future research are presented and discussed.

Heterogeneity in capture probabilities is known to produce bias in the dual system estimates that have been used to estimate census coverage in U.S. Censuses since 1980. Triple system estimation using an administrative records list as a third source along with the census and coverage measurement survey has the potential to produce estimates with less bias. This is particularly important for hard-to-reach populations. The article presents potential statistical methods for the estimation of net census undercount using three systems for obtaining population information: (1) a decennial census; (2) an independent enumeration of the population in a sample of block clusters; and (3) administrative records. The 2010 Census Match Study will create census-like files for the entire nation using federal and commercial sources of administrative records. The 2010 Census Coverage Measurement Survey is an enumeration in a sample of block clusters that is independent of the 2010 decennial Census.

Several hundred special or supplementary scales were created for the original Minnesota Multiphasic Personality Inventory (MMPI). At the time of the release of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) in 1989, 15 supplementary scales were included in, or developed for, this revised test. The degree to which the MMPI-2 supplementary scales provide either new information or data that are redundant with that already provided by the MMPI-2 basic scales has not been investigated in prior research. The current study examines the incremental validity of the MMPI-2 supplementary scales in a sample of 597 adult psychiatric inpatients using criterion measures composed of other self-report instruments and clinicians' ratings of psychopathology. MMPI-2 basic and supplementary scale data were entered in a series of hierarchical regression analyses to statistically evaluate the degree to which the supplementary scales provided incremental contributions in the prediction of variance on outcome measures. These results were compared with levels of prediction achieved by forced entry of all 13 of the basic scales and with incremental variance produced by the assignment of random 7-score values to the supplementary scales. Major findings indicate that the inclusion of supplementary scale data only marginally increased the proportion of variance accounted for in external criterion variables.
