Descrizione
Since 2006, retailers and manufacturers in the UK have begun using front of pack (FOP) nutrition labelling on foods. Presently, around four fifths of foods in UK supermarkets carry FOP labelling. There have been many studies of consumer understanding of FOP labelling, and of use of FOP labelling in experimental settings. However, little is known about how consumers use FOP labelling in real-life shopping situations. This project will investigate the use of FOP labelling during real-life shopping situations, and explore the feasibility of a trial of two interventions aimed at amplifying the impact of FOP labelling - tailored feedback to consumers on food purchases, and interactive education about FOP labelling.
Two recent studies involved participants being tailed by researchers during real-life shopping situations, in order to investigate facilitators and barriers to buying healthy foods. Transcripts of the interviews from these studies will be re-analysed with a focus on the role of FOP labelling in food purchasing decisions. A new qualitative study will then be conducted with innovative data collection techniques. Participants will be asked to wear SenseCam - a wearable camera that takes time-stamped first-person photos at regular intervals. After the shop, the participants will be interviewed, and images collected by SenseCam will be used to aid recall of the food purchase decisions at each stage in the shop. These interviews will be used to gauge the influence of FOP labelling in food purchase decisions, in relation to other competing influences. Participants will also be asked to consider how the influence of FOP labelling might be amplified in future shopping experiences, and their responses will feed into the development of two interventions. The tailored feedback intervention will consist of automatic delivery of information about the FOP labels of recently purchased products with alternatives from within the same product range with a more healthy FOP label profile. The interactive education intervention will consist of a web-based programme that educates individuals about how FOP labelling systems are designed and work, what consumers should look for in different food product ranges, and the range of FOP labels that are likely to appear in different food product ranges.
A pilot RCT will then be conducted, which will assess the feasibility of conducting a full RCT of these two interventions. Stores from the Co-operative supermarket chain will be the setting. Approximately 400 participants will be recruited from all Co-operative store card holders. They will be randomised into four arms: control; tailored feedback only; interactive education only; tailored feedback and interactive education. Data collection will take place over 12 weeks. During this time, all food purchases made by participants using their Co-operative store cards will automatically be relayed to the researchers. For the first four weeks of data collection, no interventio
Front of pack (FOP) nutrition labels are displayed on most foods available in UK supermarkets but little is known about how they are used in real-life shopping situations, or whether their influence can be amplified to encourage healthier food purchases.
This project involves three phases. Phase 1 is secondary analyses of two studies where researchers accompanied shoppers and observed behaviour. The analyses will focus on the influence of FOP labels. Phase 2 is a qualitative study of use of FOP labels in shopping situations using innovative data collection techniques. 30 participants will conduct a routine shop wearing SenseCam (a wearable camera which automatically takes photos from a first-person viewpoint at a standard interval), and 30 participants will conduct both a routine shop and a 'healthy shopping' task whilst wearing SenseCam. The images will be used to prompt recall in a semi-structured interview conducted immediately after the shop. Participants will be asked about two interventions to amplify the impact of FOP labels (I1) tailored feedback promoting foods with healthier FOP labels than previous purchases, (I2) a web-based education programme about FOP labels. Phase 3 is a pilot RCT of the effectiveness of I1 and I2. The pilot RCT will be conducted in Co-op supermarkets nationwide. 400 participants will be randomised to four arms: control; I1; I2; I1 and I2. Data collection will take place over 12 weeks, during which time electronic sales data from the participa
