Consumers' Perceptions of the Australian Health Star Rating Labelling Scheme.

The objective of this study was to explore consumers' use and perception of the Australian Health Star Rating (HSR). A purposive sample of fifteen Australian grocery shoppers was recruited into four focus groups using a supermarket intercept strategy. Focus group discussions were recorded, transcribed and analysed using an iterative approach to thematic analysis. Three key themes emerged from analysis. The HSR was seen as simple, uncluttered, easy to understand and useful for quick comparison across products. The nutrition information was viewed positively; however, there was little confidence in the HSR due to a perceived lack of transparency in the criteria used to determine the number of stars. Highly processed foods were generally seen as having inflated ratings and participants expressed concern that this would increase consumption of these products. Finally, there was a belief that the HSR had a lack of negative imagery limiting the dissuasive impact on consumers when presented with low-rated foods. Consumers saw benefits in the HSR but were sceptical about how the ratings were derived. Transparency about the development and education on the application may assist with consumers' perception of the HSR.
