Identifying Optimal Smoking Cessation Intervention Components (Cessation)

Participants randomized to minimal in-person counseling will receive one 3-minute in-person session occurring one week before their target quit day. The clinician will also inform the participant of the sort of phone counseling follow-up that s/he will receive in 1 and 2 weeks after their quit date. (This resembles the real-world situation in which the clinician discusses the sort of follow-up intervention a patient will receive.)

Participants randomized to intensive in-person counseling will receive three 20-minute face-to-face counseling sessions: one during the week before the target quit day, one on the target quit day and one during the week after the target quite day. The counseling will include intra-treatment social support and skill-based competence intervention components.

Participants randomized to this condition will receive minimal phone counseling consisting of one 10-minute phone counseling session on the morning of the target quit day. This session will address motivation to quit, strategies for coping with urges to smoke and use of the medication, and will provide support. Thus, all participants will get some counseling support on the quit day, which reflects the fact that initial lapses often occur on the target quit day, and quit day smoking is an important determinant of ultimate outcome.

Participants randomized to this condition will receive intensive phone counseling consisting of three 15-minute phone sessions (on the morning of the target quit day and on days 2 and 10 after the quit day). The content of the target quit day phone call will emphasize intra-treatment social support, skill execution and avoidance of danger situations. The quit day phone call is intended to augment any other clinician counseling received either on the phone or in person; such interventions tend to have additive effects and produce strong dose-response effects as a function of the duration of the counseling intervention.

If randomized to this condition: After the target quit day: Patch: IF \> 10 cigs/day: one 21 mg nicotine patch per day for 12 weeks, THEN one 14 mg nicotine patch per day for 2 weeks, THEN one 7 mg nicotine patch per day for 2 weeks. IF \< or = 10 cigs/day: one 14 mg nicotine patch per day for 12 weeks, then one 7 mg for 4 weeks. Gum: IF \> 24 cigs/day: ten 4 mg nicotine gum per day for 16 weeks. IF \< or = 24 cigs/day: ten 2 mg nicotine patch per day for 16 weeks.

If randomized to this condition: After the target quit day: Patch: IF \> 10 cigs/day: one 21 mg nicotine patch per day for 4 weeks, THEN one 14 mg nicotine patch per day for 2 weeks, THEN one 7 mg nicotine patch per day for 2 weeks. IF \< or = 10 cigs/day: one 14 mg nicotine patch per day for 4 weeks, then one 7 mg for 4 weeks. Gum: IF \> 24 cigs/day: ten 4 mg nicotine gum per day for 8 weeks. IF \< or = 24 cigs/day: ten 2 mg nicotine gum per day for 8 weeks.

If randomized to only the Pre-Quit Nicotine Gum condition (and not the Pre-Quit Nicotine Patch): Before quitting: Everyone will have ten 2 mg nicotine gum per day for 2 weeks before the target quit day.

If randomized to only the Pre-Quit Nicotine Patch condition (and not the Pre-Quit Nicotine Gum): Before quitting: Everyone will have one 14 mg nicotine patch per day for 2 weeks before the target quit day.

If randomized to both the Prequit Patch and Prequit Gum Conditions: Before quitting: Everyone will have ten 2 mg nicotine gum per day for 2 weeks and one 14 mg nicotine patch per day for 2 weeks before the target quit day.
