The Study
Smoking is the largest single cause of preventable illness in the UK, but whilst adult smoking prevalence has been falling, smoking amongst teenagers has risen over the last decade. Much money, time and effort is spent on anti-smoking programmes in UK schools, yet there is no rigorous evidence to support the effectiveness of any of these programmes.

This project evaluated a different approach: it was not classroom-based or teacher-delivered; instead, peer-nominated students in Year 8 (aged 12-13) were recruited as 'peer supporters' and given intensive training off the school premises by professional health promotion staff. The peer supporters were trained to intervene effectively with their Year 8 peers in everyday situations to discourage them smoking (Audrey et al., 2004). This approach was based on that used in a successful intervention to reduce unsafe sexual behaviour among gay men (http://www.cdc.gov/hiv/projects/rep/pol.htm). Prior to the full-scale trial, this approach was tested in a feasibility study conducted in four South Wales schools in the mid 1990's (Bloor et al, 1999).

The large scale effectiveness trial, known as ASSIST, was funded by a grant of £1.5m from the Medical Research Council, and was led by Professor Laurence Moore from Cardiff Institute of Society, Health and Ethics, and by Dr Rona Campbell from the Department of Social Medicine at the University of Bristol. The project aimed to test the effectiveness of the intervention using a pragmatic cluster randomised trial research design. Fifty-nine schools in South Wales and the Bristol area of England were randomly allocated either to continue with their normal smoking education programme, or to do so with additional peer supporter training.

Students were followed up for two years to see whether smoking prevalence in the intervention schools was lower than that in the schools which did not receive the training. In addition, the study involved a substantial component of process evaluation, as well as a health economics analysis to assess the gains of the intervention against the costs of achieving them.

The analysis of the trial is complete and a number of papers reporting the results of the process, outcome and economic evaluations have been published (see below) or are under preparation. Two dissemination conferences were held in November 2004, in which the results of the trial were fed back to participating schools. These dissemination events also attracted representatives of local, regional and national health authorities, and included discussions on how the ASSIST intervention could be implemented and funded in future.

Following positive findings from the evaluation the ASSIST programme is being rolled out in schools in 'Communities First' areas in Wales, in Bristol PCT and in Tower Hamlets PCT in London.
