This study investigated feasibility and acceptability of a new email-delivered intervention promoting fruit and vegetable consumption in a university-based population of Australian young adults. The study explored whether there are differences in the reported feasibility and acceptability between demographic groups within the population of interest and at three levels of intervention intensity. The email-delivered intervention program consists of an implementation intention 'planning task' and between 3 and 15 short email messages over a 15-day study period. The intervention program was developed using the Theory of Planned Behaviour and was designed to modify perceived behavioural control. One hundred and ten participants (mean age = 19.21 years, 25.6% male) completed the feasibility and acceptability questionnaire at Day 15. This questionnaire contained items about all intervention components. High acceptability and feasibility scores were found for all intervention parts and at all levels of intervention intensity. There were few significant differences in the reported acceptability of items between key demographic sub-groups, and no differences in reported acceptability at different levels of intervention intensity. These results suggest that this email-delivered intervention is an acceptable and feasible tool for promoting fruit and vegetable consumption for participants in the target population.
本研究旨在探讨一种新的电子邮件干预措施在澳大利亚年轻成年人大学生群体中促进水果和蔬菜消费的可行性和可接受性。本研究探讨了在目标人群中，不同人口统计学群体和三种干预强度水平下，报告的可行性和可接受性是否存在差异。该电子邮件干预方案包括实施意图“规划任务”以及在 15 天的研究期间内发送 3 到 15 封简短的电子邮件。该干预方案是使用计划行为理论开发的，旨在改变感知行为控制。110 名参与者（平均年龄=19.21 岁，25.6%为男性）在第 15 天完成了可行性和可接受性问卷。该问卷包含了所有干预部分的项目。所有干预部分和所有干预强度水平的接受性和可行性得分都很高。在关键人口统计学亚组之间，报告的项目接受性差异很小，不同干预强度水平的报告接受性也没有差异。这些结果表明，这种电子邮件干预措施是一种可接受和可行的工具，可用于促进目标人群中水果和蔬菜的消费。
