ABSTRACT
In this brief report, we present MMPI-2 basic validity and clinical scale data of Latino-descent persons from Puerto Rico (n = 290), Mexico (n = 1,920), and the United States (n = 28). All were administered one of three Spanish translations of the MMPI-2. A review of the mean scores of these respective groups indicates similarities across all scales. Differences among these three groups, with the exception of the Mf scale (which is keyed to sex), were well within the one standard deviation band. More importantly, these findings are promising given the fact that three different translations of the MMPI-2 were applied.

54 African and Mexican American adolescent first-time offenders were examined with the MMPI-A to evaluate ethnic differences. Multivariate analyses by ethnicity and MMPI-A scales (validity, clinical, content, and supplementary scales) were not significant; however, there was a significant univariate difference where African American adolescents scored significantly higher on the Repression scale than the Mexican American group. A greater percentage of within-normal-limits profiles were African American (50%) than Mexican American (25%). Research and clinical implications for using the MMPI-A with these groups are discussed.

This study examined the factor structure of the Preschool Behavior Questionnaire in a sample of African-American, Euro-American, Asian, and Hispanic children. The sample consisted of 304 children (141 boys, 163 girls) 3- and 4-yr.-old and enrolled in Head Start. A principal component analysis with a varimax rotation was conducted and two- and three-factor solutions were extracted. A two-factor solution produced a clear interpretive structure representing Fowler and Park's 1979 Aggressive-Hyperactive-Distractible and Anxious-Fearful factors. Even though a three-factor solution was statistically appropriate, extracting more than two factors yielded dimensions difficult to interpret. Examination of subscale differences among ethnic groups indicated significant group effect for ethnicity. Further examination showed that Euro-American children are rated significantly higher on the Anxious subtest than Latino, African-American, and Asian children, but there were no other subscale differences. Clinical and research implications are discussed.

Three groups of four dogs each underwent proximal gastric vagotomy, truncal vagotomy, or truncal vagotomy with pyloroplasty. Two dogs had sham operations. Gallbladder bile was aspirated and measured. Aliquots were cultured and assayed for cholesterol, phospholipid, and bile salts initially and at subsequent laparotomies. Both truncal vagotomy groups showed marked increases in aspirate volume at subsequent laparotomies. The sham and proximal gastric vagotomy groups showed a small initial decrease in mean aspirate volume without further significant changes. When the bile assay data were plotted on triangular coordinates, all point for all groups remained well within the area of cholesterol solubility. Nevertheless, two dogs in each truncal vagotomy group were found to have gallstones. No stones were found in the sham and proximal gastric vagotomy groups. Proximal gastric vagotomy appears to preserve fasting gallbladder bile volume and does not alter bile composition in the dog.
