Eir everyday lives. Methods Design and sample Between June 2011 and March 2012 young adult girls smokers (N=301) have been recruited from eight postcode sectors from inside 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) making use of random place quota sampling. 
The postcode sectors had been randomly chosen, stratified by DEPCAT score, which is a measure of multiple deprivation, to make sure coverage of a selection of socioeconomic backgrounds. Inside each and every postcode sector, marketplace recruiters have been instructed to recruit either six or seven participants, applying the door knock approach, as outlined by quota controls on age (184255) and each day consumption (lightmoderate smokers were defined as those smoking 14 cigarettes every day or less, heavy smokers as these smoking 15 cigarettes per day or more). The industry recruiters, who had been briefed about the study Neferine protocol but blind for the purpose with the study, informed all prospective participants that the study was concerned with smokers’ opinions of cigarette packaging.

On the other hand, as all of the top rated 25 selling cigarette brand variants inside the UK come in either King Size or Superkings packs,10 which are slightly larger than the regular King Size pack, industry recruiters had been offered a box of Superkings plain packs and instructed to work with these exactly where acceptable.
