The influence of trust and social identity in farmers' intentions to report suspected emergency disease outbreaks

This study examines the influence of trust on farmers' intentions to report suspected disease on their farm. Disease reporting is essential to detect and respond to disease early, thereby minimising its impacts on agriculture businesses, the economy, and the environment. Trust has been identified as an important factor influencing farmers' disease reporting intentions but has not been quantitatively investigated. We use an established model of trust-the Integrative Model of Organisational Trust (IMOT)-to conceptualise how trust influences disease reporting intentions. We also examine how social identity is related to trust and disease reporting. Australian plant, livestock, and aquaculture farmers (N = 41) completed an online questionnaire developed from existing validated measures and we also developed two new measures for disease reporting intentions. Trust in government positively and significantly predicted farmer intentions to report suspected disease outbreaks, explaining 26% of the variance. For every one-unit increase in trust, disease reporting intentions increased by over four times. Results also support the role of shared values and group membership as aspects of social identity that influence trust and disease reporting. These results highlight the importance of government decision-makers developing and maintaining trust with farmers to support early detection and response to emergency disease outbreaks.
