Abstract

Although customer support is critical to the wider uptake of nudging strategies to promote fruits and vegetables (FV) in institutional food service (FS) settings, empirical research is sparse and typically based on small convenience samples. An online survey was conducted to assess support, perceived effectiveness and intrusiveness of nine nudge types drawn from Münscher et al.'s Taxonomy of Choice Architecture. We focused on the setting of campus FSs across Canada. A national sample of post-secondary students regularly using campus FSs was used (N 1057). Support for changing the range of options (B3) was the highest, closely followed by changing option-related effort (B2) and changing option-related consequences (B4). Facilitating commitment (C2), changing default (B1) and providing a social reference point (A3) received lowest support. Furthermore, we extracted three clusters of respondents based on perceived effectiveness and intrusiveness of nudge types. Characterised by a relatively low level of perceived effectiveness and moderately high level of intrusiveness, Cluster 1 (61⋅7 % of the sample) reported the lowest support for nudges. Cluster 2 (26⋅6 %), characterised by intermediate effectiveness and low intrusiveness of nudging, reported a high level of support for nudges. Lastly, Cluster 3 (11⋅7 %), characterised by high perceived effectiveness of as well as high perceived intrusiveness, reported the highest level of support for nudges. Findings confirm overall support for FV nudging, with significant differences across nudge types. Differences in customers' acceptance and perception across nudge types offer campus FS operators initial priors in selecting nudges to promote FV.

校园食品服务用户对富含水果和蔬菜的食物的推送策略的支持:来自加拿大全国大样本的调查结果。
尽管客户支持对于在机构食品服务(FS)环境中更广泛地推广水果和蔬菜(FV)的策略至关重要,但实证研究很少,通常基于小规模的便利样本。进行了一项在线调查,以评估来自Münscher等人的Taxonomy of Choice Architecture的九种轻推类型的支持、感知有效性和侵入性。我们关注的是加拿大各地校园FSs的设置。使用了定期使用校园FSs的全国中学生样本(N 1057)。对改变选项范围的支持率最高(B3),紧随其后的是改变与选项相关的努力(B2)和改变与选项有关的后果(B4)。促进承诺(C2)、改变默认(B1)和提供社会参考点(A3)获得的支持率最低。此外,我们根据推送类型的感知有效性和侵入性提取了三组受访者。第1组(样本的61·7%)的感知有效性相对较低,侵入性相对较高,对轻推的支持率最低。第2组(26∙6%)以轻推的中等有效性和低侵入性为特征,报告称对轻推的支持率很高。最后,第3组(11·7%)以高感知有效性和高感知侵入性为特征,报告了对轻推的最高支持水平。研究结果证实了对FV轻推的总体支持,不同轻推类型之间存在显著差异。不同推送类型的客户接受度和感知度的差异为校园FS运营商提供了选择推送来推广FV的初始优先级。
