Reliability and controlling effects of three procedures for self monitoring smoking

Measurement reliability and controlling effects of 3 procedures for self monitoring smoking were examined. In Experiment I, subjects monitored their smoking rates using each recording procedure for 1 wk. Results showed continuous recording to be the most reliable procedure. Self reports indicated continuous recording to be most accurate, bothersome to use, and reactive. In Experiment II a between subject design evaluated the 3 procedures over a 5 wk period. Continuous recording led to pronounced reductions in reported smoking rate and greater attrition. Reported smoking rates did not significantly differ at a 6 mth followup. Results were related to demands imposed by recording procedures and differing interrecording intervals.
