Smoking cessation by mail: a comparison of standard and personalized correspondence course formats

Self-Instructional behavior-change programs for reducing risks to health are potentially widely available, acceptable and cost-effective. This paper reports outcomes of a smoking cessation program administered by mail. Two hundred and eight smokers were allocated systematically to a quit kit control condition (n = 40), to a standard correspondence course (n = 86) and to a personalized correspondence course prepared with the aid of a microcomputer (n = 82). There were significantly higher rates of abstinence after the course for correspondence course participants compared to controls, but these differences did not persist at three-month and nine-month follow-ups. There were no differences between the personalized and standard courses on abstinence rates, number of cigarettes smoked per day, or return of feedback forms on each lesson. There were associations between self-efficacy strength and reduced rates of smoking, and active participation in the course was associated with lower smoking rates.
