目標：本研究目的是探討有六歲以下嬰幼兒之母親政府信任、食安風險感知以及食安避險行為之間的關係，以及探討社經地位是否為三者關係之修飾因子。方法：研究樣本來自台北某一教學醫院439位有六歲以下嬰幼兒的母親，以一對一面訪的方式收集資料，其食安避險行為包括購買當季蔬菜和注意食品添加物。分析方法使用路徑分析進行多變項分析。結果：母親對於政府的信任提高會降低對食安的擔憂程度、嚴重程度以及採取食安避險行為的機率，而擔憂程度提高則會提高採取食安避險行為的機率，但自覺障礙提高反而會減少採取食安避險行為的機率。多群組分析結果顯示，社經地位中的教育程度指標為政府信任、食安風險感知以及食安避險行為三者關係之修飾因子。結論：在面對食安風險時，母親的政府信任確實會影響食安風險感知與食安避險行為。建議未來政府在處理食安風險時，應更注重治理方式以增進民眾對政府的信任與針對不同族群採取不同的風險溝通方式。

Objectives: This study examined the relationships among trust in food safety, risk perception, and risk avoidance behaviors among mothers with children younger than 6 years of age and determined whether socioeconomic status moderates those relationships. Methods: The study participants were recruited from a teaching hospital in Taipei, and face-to-face interviews were conducted with 439 mothers. Path analysis was used to analyze the relationships among trust in the government, risk perception, and risk avoidance behaviors regarding food safety. Risk avoidance behaviors included buying seasonal vegetables and paying attention to food additives. A multigroup analysis was used to assess whether socioeconomic status was a moderating variable. Results: The results of the path analysis indicated that the mothers’ trust in the government reduced their worry about food safety risks, perceived severity of food safety risks, and the probability of adopting risk avoidance behaviors. The perception of barriers by the mothers also reduced their probability of adopting risk avoidance behaviors. The results of this multigroup analysis demonstrated that an individual’s education level moderates the relationships among trust in government, risk perception, and risk avoidance behavior. Conclusions: Our results indicated that mothers’ trust in the government affected their perception of risk and risk avoidance behaviors. In the future, the Taiwanese government must enhance risk governance to increase people’s trust, strengthen its communication capacity about food safety risks, and design tailored programs for individuals of various socioeconomic statuses.
