Computerized Scheduling of Nicotine Gum Use

We will develop a computerized program for scheduling the use of nicotine gum. The program will woassessing a baseline smoking pattern and then prompting users when and how long to use nicotine gum.durations will be decreased and inter-gum intervals will be gradually increased until abstinence iswill consist of a credit card size computer and a program guide. The product will be suitable as eitsmoking interventions or as a stand-alone product. This Phase I project will include development ofprototype system and an 8-week feasibility study with 80 smokers. Smokers will be randomly assignedconditions: computer scheduled gum use or ad-lib gum use. Data on gum use, smoking, withdrawal symptof satisfaction and usability will be collected. Criteria for feasibility will be 1) statistically sgroups for latency to smoking relapse, number of gums used, salivary cotinine levels, and degree ofand 2) significant within treatment changes in cotinine levels and correlations between prescribed athe computer scheduled group. Data from the trial and feedback from subjects will be used to guide fdevelopment. During Phase II, a second generation prototype will be developed and evaluated in a lar
