Three-year data on a behavioral treatment for smoking: A follow-up note

A study reported by Lando (1981) compared two-stage treatment (aversion, maintenance) against three-stage treatment (preparation, aversion, and maintenance) under conditions of either intensive or minimal experimenter contact. One-year follow-up data indicated the superiority of the two-stage intensive contact procedure. The present article reports additional follow-up data at 12, 18, 24, and 36 months. Results continued to favor two-stage intensive contact. Long-term abstinence in this condition consistently exceeded 40% as opposed to less than 25% in the other conditions.
