Peer reviewedJenkinson, Josephine C. – International Journal of Disability, Development and Education, 1989
This article discusses research design problems peculiar to work with intellectually disabled subjects, such as discrepancies in uses of control groups and mental age matching, definitions of subject groups and variability within and between subject groups. Suggestions for minimizing these problems are made and alternative methodologies offered.…

Eight predictor variables from the Minnesota Multiphasic Personality Inventory, the Bender Gestalt, and a Malingering Scale differentiated 20 prison inmates faking insanity from 40 nonfaking controls. A second experiment with 22 substance abusers faking insanity and 20 schizophrenics also supports the use of the test battery to detect faking. (SLD)

Peer reviewedSchmitt, John F.; Meline, Timothy J. – Journal of Communication Disorders, 1990
Ninety-two research reports involving specifically language-impaired subjects were reviewed. Analysis showed few consistent trends with respect to subject selection, subject description, and the number and types of control groups. The importance of more complete subject descriptions and matching criteria for control groups is discussed.…

Subjects were interviewed to determine smoking habits of 9,252 current cigarette smokers (11 percent black) and 7,555 former smokers (6 percent black). More blacks than whites smoked. Blacks were three times more likely to be light smokers than heavy smokers. Effective prevention may require better understanding of cultural factors affecting…
