Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Personalised video dramatising the potential consequences of having a heart attack secondary to smoking.
The video is personalised by inserting photos of the subject, non-smoking partner and family into the video. The video duration is 8 minute. It is viewed on 2 occasions separated by approximately one week, and is viewed by the participant alone, accompanied by a study investigator.

Outcomes
Primary outcome [1] 287614 0
Smoking Cessation Rate. The outcome is assessed by carbon monoxide breath test, and subject self-report.
Timepoint [1] 287614 0
Primary timepoint: 6 months
Secondary timepoints: 2 weeks, 3 months, 12 months
Secondary outcome [1] 298531 0
Psychological impact of the personalised video. We will evaluate psychological impact using a Video Response Scale (7 point Likert scale) we have developed for this proposal, and will also assess subjective distress response to the video using the Impact of Event Scale (IES) (Horowitz et al.1979).
Timepoint [1] 298531 0
1 week
Secondary outcome [2] 298532 0
Urge to smoke. This will be measured by the Questionnaire on Smoking Urges (QSU ? Brief Version) (Tiffany et al., 1991).
Timepoint [2] 298532 0
1 week
Secondary outcome [3] 298533 0
Awareness of the negative consequences of smoking. This will be assessed on a number of dimensions including health risks and as measured by the Risk Perception Scale (adapted from Borelli et. al., 2010).
Timepoint [3] 298533 0
1 week

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Prospective subjects and partners will receive an information sheet and consent form. They will then be seen by study investigators and eligibility confirmed. Once they have signed consent, treatment allocation will occur through contacting a central blinded person. Randomisation will be used with a randomisation table created by computer software, with stratification for study centre.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be generated by randomisation computer software, with stratification for study centre.

Summary
Brief summary
Smoking remains a major preventable risk factor for cardiovascular disease. This research proposal builds on 2 observations; firstly, experiencing a heart attack is a teachable moment that enables up to 60% smokers to abruptly quit once they have experienced a heart attack; and secondly, we have demonstrated in a pilot study that it is feasible to induce smoking cessation through subjects watching a DVD containing images of him/herself, his/her partner and family digitally superimposed into a scenario depicting the person having a heart attack as a result of smoking, and the potential consequences to the partner and family. Using this novel approach, which we describe as a personalized simulated teachable moment, 7 of 13 smokers (53%) were abstinent at 6 months (published in Am J Cardiol 2010). We have since completed 20 subjects of whom 12 (60%) were abstinent at 12 months.

In the current proposal, we will evaluate the simulated teachable moment hypothesis in a prospective randomized controlled study. We will compare smoking cessation rates using the personalized DVD with the same video using actors. In addition, we will evaluate the psychological impact of the personalized video. If this study demonstrates an additive effect of the personalized simulated teachable moment in smoking cessation, its use would be supported as an adjunct to smoking cessation, which in turn would have major health benefits in our society. We will conduct the study in selected General Practices and Pharmacies to investigate its broad applicability and ability to be disseminated widely.
