Abstract
An alcohol education program and procedures for its evaluation are described. Various alcohol programs were administered to eighth grade students in ways to reduce Hawthorne effects and other experimental biases. Procedures, which were independently administered from the program delivery, are discussed whereby data were obtained pertaining to process and outcome variables. Obtaining other types of data as well is suggested in order to provide as much information as possible to assist in the interpre tation of results. Finally, various data analyses as well as sample size are considered.
