Effects of industry-level factors, brand credibility and brand reputation on brand trust in safe food: evidence from the safe vegetable sector in Vietnam

Abstract

PurposeWhile the essential role of brand trust toward consumer decision to purchase food products has been well addressed, there has been still little research on its influential factors. The primary purpose of this study was to explore factors affecting consumer trust in brands of safe vegetables.Design/methodology/approachStructural equation modeling technique was applied to test the hypothetical relationships based on a sample of 361 consumers from a face-to-face interview in the urban areas of Hanoi city, Vietnam, in March and April 2018.FindingsThe authors' findings show that both brand credibility and brand reputation positively affected brand trust. The trustworthiness of a safe vegetable system had a more important role than the competence in building brand trust. While the effects of system trustworthiness on brand trust were found directly and indirectly (through brand credibility), system competence only had an indirect influence on brand trust via brand reputation. Notably, while risk recall directly reduced brand trust, risk information caused a directly positive effect on brand trust. In addition, the impact of food hazards on brand trust was indirect through brand credibility.Practical implicationsBased on our results, the Vietnamese government and stakeholders in the safe vegetable chain should improve brand trust based on fulfilling comprehensive traceability, expanding the brand reputation and providing an appropriate risk communication strategy to the public.Originality/valueThis study is one of the first attempts to model and evaluate factors affecting brand trust in the food sector directly and indirectly.
