Possible causes for the discrepancy between the ABT report on the national Project Follow Through and the Saint Louis, Missouri program were discussed: (1) ABT data were positively biased because of non-random, differential attrition from the program and control groups; (2) positive ABT data were due to use of a particular cohort group; or (3)…

Challenges some assumptions and methods used in nutrition education practice and research, offers alternative viewpoints for studying and intervening in certain nutrition behaviors, and discusses programmatic and methodological issues which have limited the application of existing theories and data in research and practice of nutrition education.…

A review of existing evaluations of medical, educational, and counseling services for pregnant adolescents and young parents reveals methodological weaknesses. Among the suggestions for improving evaluative studies are recommendations for proper selection of control groups, improved analytic procedures, and formulation of realistic goals. (MH)

Procedures are described to conduct summative evaluations of Talents Unlimited programs. It is assumed that school counselors, administrators, or personnel minimally trained in measurement and statistics are capable of conducting the evaluation, except for doing the statistical analysis. The procedures are composed of: establishing measurable…
