The proposed study will compare the efficacy of two psychological stop smoking interventions.
The proposed study comprises a randomised controlled trial (n = 620) which will compare the efficacy of two psychological stop smoking interventions. Specifically, Allen Carr's Easyway smoking cessation programme comprising one 5/6 hour group session (plus one or two 3 hour booster sessions over the following 3 months for those who require them) and a 1-1 counselling service available via the NHS (comprising one 30 minute session and four weekly follow ups of 10-15 minutes) will be compared. The efficacy of both treatments will be followed up at 4, 12 and 26 weeks after treatment. The evaluation will be compliant with the Russell 6 Standard (which requires, amongst other things, a double blind, randomised design, chemical verification of quit outcomes, and the inclusion of all participants who received treatment in the final analysis). The findings will add to the evidence base around the use of the Allen Carr method, in particular by testing it in non-commercial settings.

Cessation of smoking
Measured in line with the Russell 6 standard (i.e. fewer than 5 incidents of smoking from the quit date, including all participants lost to follow-up as failed treatment, and confirming all successful quits via breath carbon monoxide testing). The intention to treat principle will be followed, and those lost to follow-up will be considered failed quit.
Time frame: 26 weeks post treatment commencement
Self-reported maintenance of smoking cessation questions
current cessation, number of slips, number of cigarettes in past week/month/since last session.
Time frame: 4, 12, 26 weeks post treatment commencement
