Interventions

Standard 15-minute telephone counselling DEVICE

Subjects in arm 1 will benefit from a standard 15-minute telephone counselling session with a professional adviser which resembles a normal call to the national Quit-line. The telephone counselling will be reactive, thus the smoker initiates the call to a designated number to receive advice and information based on the needs and wishes of this particular smoker. Participants can receive self-help materials and information on other smoking cessation services if they wish.

Telephone counselling

Proactive telephone counselling DEVICE

subjects in arm 2 will benefit from of five 15-minute calls from a professional adviser. Similar to the standard reactive telephone counselling, the proactive counselling will be a personal discussion and advice based on the needs and wishes of the particular participant. Together, the participant and adviser will determine a cessation date and schedule one call 3-7 days before the cessation date, one call immediately after the cessation date and three additional calls on days 3, 10 and 24, respectively, post-cessation.
