The Theory of Planned Behavior was used to determine if dietitians personal characteristics and beliefs about fresh vegetable food safety predict whether they currently teach, intend to teach, or neither currently teach nor intend to teach food safety information to their clients. Dietitians who participated in direct client education responded to this web-based survey (n=327). The survey evaluated three independent belief variables: Subjective Norm, Attitudes, and Perceived Behavioral Control. Spearman rho correlations were completed to determine variables that correlated best with current teaching behavior. Multinomial logistical regression was conducted to determine if the belief variables significantly predicted dietitians teaching behavior. Binary logistic regression was used to determine which independent variable was the better predictor of whether dietitians currently taught. Controlling for age, income, education, and gender, the multinomial logistical regression was significant. Perceived behavioral control was the best predictor of whether a dietitian currently taught fresh vegetable food safety. Factors affecting whether dietitians currently taught were confidence in fresh vegetable food safety knowledge, being socially influenced, and a positive attitude toward the teaching behavior. These results validate the importance of teaching food safety effectively and may be used to create more informed food safety curriculum for dietitians.
采用计划行为理论来确定营养学家对新鲜蔬菜食品安全的个人特征和信念是否会影响他们目前是否向客户教授食品安全信息,以及是否打算教授。参与直接客户教育的营养师回答了这项基于网络的调查(n=327)。该调查评估了三个独立的信念变量:主观规范、态度和感知行为控制。完成 Spearman rho 相关性分析,以确定与当前教学行为相关性最好的变量。进行多项逻辑回归,以确定信念变量是否能显著预测营养师的教学行为。采用二项逻辑回归来确定哪个独立变量是营养师当前是否教授的更好预测指标。控制年龄、收入、教育和性别等因素后,多项逻辑回归具有统计学意义。感知行为控制是营养师当前是否教授新鲜蔬菜食品安全的最佳预测指标。影响营养师当前是否教授的因素包括对新鲜蔬菜食品安全知识的信心、受到社会影响以及对教学行为的积极态度。这些结果验证了有效教授食品安全的重要性,并可能用于为营养师制定更有针对性的食品安全课程。
