Tailored behavioral support for smoking reduction: development and pilot results of an innovative intervention.

Reduction of smoking may increase the likelihood of eventual smoking cessation among those not ready to quit. We describe the development and acceptance of a smoking-reduction intervention that integrates telephone counseling sessions with newsletters. A computer-assisted telephone interviewing program generates real-time-tailored counseling delivered by lay interviewers. Pilot participants (n = 53) were adult smokers scheduled for outpatient procedures in a health maintenance organization, randomized to intervention or a control condition (quarterly mailings). Smoking levels were measured by self-report and biochemically. Among intervention participants continuing at 3 months, all but one rated their telephone support person positively on all dimensions. Counseling calls were 'about right' in number, and newsletters were perceived as quite personal. Intervention recipients reported smoking significantly fewer mean cigarettes per day at 3 months than at baseline, and significantly fewer than control participants. Comparisons were non-significant under intent-to-treat analyses and on biochemical measures. The program was well received by outpatients who were not ready to quit smoking, and was implemented successfully by telephone staff who had no previous smoking cessation counseling experience. An ongoing trial is evaluating effectiveness, cost and relationship to eventual cessation.
