Consumer acceptance of genetically modified food (GM) in Spain: a structural equation approach

Recent studies suggest that purchase intentions of genetically modified (GM) and other related food products are determined by individual attitudes towards the product. Simultaneously, these attitudes are formed by the perception of risks and benefits associated with the product. They are also determined by whether consumers trust the information sources. To investigate these issues, in this paper we use structural equation models and representative data from the Eurobarometer 2002 to examine these issues further. We hypothesize and test that both science interest and government confidence are key predictors for GMF risk and benefit perception. Our results support the so-called “theory of reasoned action”. That is we find unambiguous evidence supporting a structural association between behaviour, attitudes and purchase intentions towards GM food. Evidence suggests that peoples trust in science and government information source is potentially the key issue that determines further acceptance. Therefore, by shifting trust in science and information conveyed by public authorities, it is possible to make GMF products acceptable to consumers.
