Reliability generalization: exploring reliability variations on MMPI/MMPI-2 validity scale scores.

The study utilized the measurement meta-analytic method called "reliability generalization" to examine (a) the typical reliability, (b) the variability of score reliability, and (c) the factors predicting variability of score reliability on the three MMPI validity scales. Across studies the reliability coefficients on the three validity scales ranged from .16 to .93, with the F scale having the most variability, as might be expected. Regression analyses suggested that the age of participant best predicted the variation of reliability coefficients.

The MCMI-II and race.

In this study, we investigated MCMI-II profile differences in a sample of 65 Black and 164 White psychiatric inpatients. A multivariate analysis of variance (MANOVA) yielded a significant multivariate effect associated with race, with Black patients scoring significantly higher on the Histrionic, Narcissistic, Paranoid, Drug Dependent and Delusional Disorder scales. A second MANOVA was conducted on these 5 scales with a smaller sample of 46 Black and 46 White patients, who were matched for primary Axis I discharge diagnosis and matched for substance abuse comorbidity. This MANOVA did not yield a significant multivariate effect associated with race, and scale differences were attenuated.
