On the Difference Between Statistical and Practical Significance in School-based Drug Abuse Prevention Academic Article

abstract

• In recent years, a large number of research reports and review papers have claimed that effective school-based drug abuse prevention strategies have been developed and tested. 'Effectiveness' in these papers is generally assessed in terms of statistical significance. However, it cannot be assumed that a statistically significant difference observed at follow-up between an intervention group and a control group is necessarily of any practical significance. Two large scale evaluations of school-based social influence programs are used to illustrate this point, and suggestions made as to how researchers might assess and report on practical significance in future studies. 1995 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
