From the Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder--a randomized clinical trial of 579 children ages 7-9 years receiving 14 months of medication management, behavioral treatment, combination, or community care--the authors matched each African American and Latino participant with randomly selected Caucasian participants of same sex, treatment group, and site. Although Caucasian children were significantly less symptomatic than African American and Latino children on some ratings, response to treatment did not differ significantly by ethnicity after controlling for public assistance. Ethnic minority families cooperated with and benefited significantly from combination (multimodal) treatment (d = 0.36, compared with medication). This incremental gain withstood statistical control for mother's education, single-parent status, and public assistance. Treatment for lower socioeconomic status minority children, especially if comorbid, should combine medication and behavioral treatment.

Few studies have described the woman who chooses breast-feeding by more than simple demographics. The purpose of our study was to characterize new mothers by their infant feeding decisions, by demographic and obstetrical data, and by sources of personal support they received during their pregnancies and in making their infant feeding decisions. To this end, 220 were interviewed, including 116 who chose to breastfeed. Breast-feeding women were more likely to be older, more educated, married, more affluent, experienced with breast-feeding, to have demonstrated good prenatal habits, and to have received support from other sources than those who chose bottle feeding. Participation in Lamaze classes, previous successful breast-feeding, and maternal education were significant predictors of feeding choice, and mode of delivery predicted duration of breastfeeding. Low income women who chose breastfeeding resembled low income bottle feeders in certain medical/social factors, but they showed support patterns similar to middle to upper income women.

This research focused on the design of a decision-support system to assist blood bankers in identifying alloantibodies in patients' blood. It was hypothesized that critiquing, a technique in which a computer monitors human performance for errors, would be an effective role for such a decision-support system if the error monitoring was unobtrusive and if the critiquing was in response to both intermediate and final conclusions made by the user. A prototype critiquing system monitored medical technologists for (a) errors of commission and errors of omission, b) failure to follow a complete protocol, (c) answers inconsistent with the data collected, and (d) answers inconsistent with prior probability information. Participants using the critiquing system had significantly better performance (completely eliminating misdiagnosis rates for 3 out of 4 test cases) than a comparable control group. Detailed analysis of the behavioral protocols provided insights into how specific design features influenced performance. Practical applications of this research include its use (after refinements) as a tool for routine antibody identification in blood banks.
