Primary Outcome Measures:
  • Smoking cessation [ Time Frame: 14 months post baseline ] [ Designated as safety issue: No ]
    We measure the 30 days point prevalence abstinence rate. We measure whether participants have been totally smokefree for at least 30 days prior to the follow-up date.


Secondary Outcome Measures:
  • Smoking cessation [ Time Frame: 3 month post baseline ] [ Designated as safety issue: No ]
    We measure the 30 days point prevalence abstinence rate. We measure whether participants have been totally smokefree for at least 30 days prior to the follow-up date.

  • smoking cessation [ Time Frame: 8 month post baseline ] [ Designated as safety issue: No ]
    We measure the 30 days point prevalence abstinence rate. We measure whether participants have been totally smokefree for at least 30 days prior to the follow-up date.

  • Change in self-efficacy [ Time Frame: At 3, 8 and 14 months ] [ Designated as safety issue: No ]
    Self-efficacy (SE) is measured on a 12 item scale. SE describes the individuals belief in own capacity to refrain from smoking in 12 specific situations. SE change is defined af the difference between baseline SE and SE at the 3,8 and 14 months follow-ups.

  • Motivational change [ Time Frame: At 3, 8 and 14 months ] [ Designated as safety issue: No ]
    Motivation was measured on a 10 point scale. ("How important is it for you to quit smoking"). Motivational change is defined af the difference between baseline motivation and motivation at the 3,8 and 14 months follow-ups.

  • Stage of change [ Time Frame: At 3, 8 and 14 months ] [ Designated as safety issue: No ]
    A measure of the participants intentions to quit smoking in the future ("Do you have plans to quit smoking? yes, within the next 30 days; yes, within the next six months; yes, but I no specific plans; No").

  • Smoking cessation expectations [ Time Frame: at 3,8,14 months ] [ Designated as safety issue: No ]
    We look at differences from baseline to follow-up with regard to participants perception of being smokefree on a six item scale: activities, physical fitness, health, appearance, happiness, stress.

Arms Assigned Interventions
Experimental: Telephone counselling Device: Standard 15-minute telephone counselling
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.
Other Name: Stoplinien.dk
Device: Proactive telephone counselling
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.

Experimental: web-based smoking cessation programme Device: Interactive web-based smoking cessation programme
Subjects in arm 3 will benefit from a tailored and interactive web-based smoking cessation programme. Besides interactive and personalised information generated on the webpage, the participant will receive by e-mail and SMS tailored feedback messages based on the particular profile of the participant on particular dates as well as topics during the cessation period depending on how well the cessation is proceeding.

Detailed Description:

Smoking remains the most important threat to public health. The majority of smokers wish to quit smoking and every year a substantial part of smokers makes a quit attempt. However, the majority of smokers tries to quit unassisted and existing smoking cessation interventions are underused. In this study we test the effectiveness of four different smoking cessation interventions in a randomized controlled trial. The study provides knowledge on factors important for recruitment and gives indication on potential reach of interventions among the general population. This knowledge can help us in designing interventions that is both effective but also have a high reach in the general population.
