This study evaluates the influences on food handlers' intention to conduct safe handling behaviours in food service settings in Brazil and the United Kingdom, focusing on Optimistic bias (OB). Although OB has been identified in food handlers in other studies, this is the first study evaluating the role of OB in determining behavioural intention. Three hundred participants, from the United Kingdom (n = 150) and Brazil (n = 150), completed a Theory of Planned Behaviour - based questionnaire, including additional questions about OB. For Brazilian food handlers, Attitude had a significant influence on Behavioural Intention followed by Subjective Norm, while Perceived Behavioural Control and OB did not significantly influence Behavioural Intention. For the United Kingdom, Perceived Behavioural Control had the largest influence, followed by Attitude, and then OB. Results suggest that cultural differences may influence predictors of behavioural intention, and that OB can contribute to predicting engagement in safe handling behaviours. Results contribute to a better understanding of the influences on food safety related behaviours.
本研究评估了巴西和英国食品服务环境中食品处理人员实施安全处理行为的意图的影响因素，重点关注乐观偏差（OB）。尽管在其他研究中已经确定了食品处理人员的 OB，但这是第一项评估 OB 在确定行为意图中的作用的研究。300 名参与者（英国 n=150，巴西 n=150）完成了基于计划行为理论的问卷，其中包括关于 OB 的其他问题。对于巴西的食品处理人员，态度对行为意图有显著影响，其次是主观规范，而感知行为控制和 OB 对行为意图没有显著影响。对于英国，感知行为控制的影响最大，其次是态度，然后是 OB。结果表明，文化差异可能会影响行为意图的预测因素，而 OB 可以有助于预测安全处理行为的参与度。研究结果有助于更好地理解食品安全相关行为的影响因素。
