An Experiment in Smoking Dissuasion Among University Freshmen: A Followup.

An experimental design based on 2208 participants tested delayed efficacy of printed and novelty material for dissuading university students from smoking. Data from questionnaires completed 16 to 18 months following an anti-smoking campaign indicated some small deterrent effects among those exposed vs. those in the control group. Thus a slight sleeper effect was found among these university lower-classmen whose responses during the semester immediately following the experiment had shown no significant change.
