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 '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 ( 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.
虽然客户支持对于更广泛地采用推动机构食品服务中水果和蔬菜摄入的推动策略至关重要，但实证研究很少，而且通常基于小的便利样本。我们进行了一项在线调查，以评估来自 Münscher 的选择架构分类法的九种推动类型的支持度、感知有效性和侵扰性。我们专注于加拿大校园 FS 的设置。使用了一个经常使用校园 FS 的全国性大学生样本（1057 人）。改变选择范围（B3）的支持率最高，其次是改变与选择相关的努力（B2）和改变与选择相关的结果（B4）。促进承诺（C2）、改变默认（B1）和提供社会参考点（A3）的支持率最低。此外，我们根据推动类型的感知有效性和侵扰性提取了三个受访者群体。以感知有效性和侵扰性相对较低为特征的第 1 组（样本的 61.7%）对推动的支持率最低。以中等有效性和低侵扰性为特征的第 2 组（26.6%）对推动的支持率较高。最后，以高感知有效性和高感知侵扰性为特征的第 3 组（11.7%）对推动的支持率最高。研究结果证实了对 FV 推动的总体支持，不同推动类型之间存在显著差异。客户对不同推动类型的接受度和感知度的差异为校园 FS 运营商在选择促进 FV 的推动类型方面提供了初步的优先考虑因素。
