Eir everyday lives. Procedures Design and sample Between June 2011 and March 2012 young adult girls smokers (N=301) have been recruited from eight postcode sectors from within the six most populated towns and cities in Scotland (Glasgow, Edinburgh, Aberdeen, Dundee, Paisley PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21330118 and East Kilbride) get CFMTI applying random place quota sampling. The postcode sectors were randomly selected, stratified by DEPCAT score, which can be a measure of various deprivation, to make sure coverage of a selection of socioeconomic backgrounds. Inside every postcode sector, industry recruiters have been instructed to recruit either six or seven participants, making use of the door knock system, in accordance with quota controls on age (184255) and day-to-day consumption (lightmoderate smokers were defined as these smoking 14 cigarettes every day or significantly less, heavy smokers as those smoking 15 cigarettes a day or a lot more). The market place recruiters, who had been briefed concerning the study protocol but blind towards the objective with the study, informed all prospective participants that the study was concerned with smokers’ opinions of cigarette packaging. If people had been prepared to participate and readily available for the duration on the study, they were asked to finish a recruitment questionnaire, which incorporated the Fagerstr Test for Nicotine Dependence9 and concerns relating to brand variant smoked, danger perceptions and cessation behaviour (eg, motivation to quit and attempts to quit). To ensure only smokers have been recruited, participants were asked to provide a breath sample using a piCO+ Carbon Monoxide monitor (Bedfont Scientific, Kent, England) and also an empty cigarette pack; inside the 4 situations where a participant only had a complete pack, recruiters took a photo of their pack and texted this to a member with the research team. Ethics approval was obtained from the ethics committee of the Marketing and advertising Division in the University of Stirling. Participants provided informed consent ahead of participating. Materials and procedure Participants have been informed about the study protocol by marketplace recruiters and, if they gave consent, had been offered with a `completion’ pack. Every single completion pack incorporated seven brown ( plain) cigarette packs. TheseMoodie CS, Mackintosh AM. BMJ Open 2013;3:e002402. doi:ten.1136bmjopen-2012-Young adult females smokers’ response to using plain cigarette packaging brown packs have been only suitable for participants who smoked King Size cigarettes, as was the case within a pilot study applying the identical strategy.3 As 9 of the best 10 promoting cigarette brand variants in the UK are available in King Size packs most smokers would happen to be eligible for study inclusion. Nonetheless, as all the major 25 selling cigarette brand variants inside the UK come in either King Size or Superkings packs,ten which are slightly larger than the normal King Size pack, industry recruiters were offered a box of Superkings plain packs and instructed to utilize these exactly where proper. This involved replacing the seven King Size brown packs within the completion pack with seven Superkings brown packs if an individual smoked a Superkings brand or other longer cigarettes, including Slims or Superslims. The plain packs had been otherwise identical, having a fictitious brand name Kerrods, to stop copyright breach, and all relevant legal markings and a barcode. The completion packs also included 5 numbered questionnaires, labelled by day and date, and a timetable explaining when to use their own packs as well as the Kerrods packs and when to complete and return every with the five questionnaires.
