Insufficient adherence to dietary guidelines underscores the need for effective interventions promoting healthy eating, including dairy consumption, among Canadian families. Research suggests that web-based interventions grounded in user research and behavior change theories can effectively support dietary improvements. However, few theory-driven digital interventions specifically target dairy consumption in families.
This study aims to describe the development of a web-based nutrition intervention, Dairyathlon, designed to promote dairy consumption among families using the IDEAS (Ideate, Design, Assess, and Share) framework. In addition, it evaluates user experience (UX) with the web-based platform.
Following the IDEAS framework, family perspectives and beliefs regarding dairy consumption were explored through ethnographic research and interviews. Behavior change techniques, based on the theory of planned behavior, were integrated to enhance attitudes and perceived behavioral control toward dairy intake. These techniques underwent iterative design, prototype testing, and refinement. UX was assessed with the AttrakDiff questionnaire, comparing families using Dairyathlon to those using the Canadian Food Guide (CFG). Children and parents completed the questionnaire after the presentation of the platform (PRE) and following 8 weeks of use (POST). AttrakDiff evaluates pragmatic quality (PQ), hedonic stimulation (HSQ), hedonic identity (HIQ), and attractiveness dimension (ATT) on a scale from -3 to +3, with >1 considered optimal, 0-1 acceptable, and < 0 suboptimal.
Between April 2019 and August 2020, Dairyathlon was developed to enhance families' attitudes and perceived control over dairy consumption, adhering to the IDEAS framework. Users' experience assessments were conducted among 29 families and showed significantly higher scores for Dairyathlon compared to the reference platform (CFG) at both pre- and postassessments (P<.001). Although both platforms were initially rated as optimal, UX ratings decreased after use: PRE (1.7, SD 0.6) to POST (1.4, SD 0.8) in the Dairyathlon group (mean difference of 0.4, 95% CI 0.2-0.7; P=.002), and (1.4, SD 0.6) to (0.9, SD 0.6) in the CFG group (mean difference = 0.6, 95% CI 0.5-0.6; P<.001). After using Dairyathlon, children (n=45) rated all UX dimensions as optimal, with scores of PQ (1.4, SD 1.0), HSQ (1.6, SD 1.0), HIQ (1.4, SD 1.1), and ATT (1.7, SD 0.9). Parents (n=50) also rated most dimensions as optimal, with scores of 1.2 (SD 1.0) for PQ, 1.4 (SD 0.8) for HIQ, and 1.6 (SD 0.8) for ATT. However, the HSQ dimension received a slightly lower rating of 0.9 (SD 0.8), indicating a need for improvement in adult stimulation.
This study highlights the effectiveness of the IDEAS framework in developing a web-based intervention to promote dairy consumption. The Dairyathlon platform's UX was rated as optimal, especially for visual attractiveness, though the stimulation dimension requires improvement for adults. Future research will evaluate its impact on dairy consumption, diet quality, and family health status.
对饮食指南的依从性不足凸显了在加拿大家庭中开展有效干预措施以促进健康饮食（包括乳制品消费）的必要性。研究表明，基于用户研究和行为改变理论的网络干预措施可以有效地支持饮食改善。然而，很少有理论驱动的数字干预措施专门针对家庭中的乳制品消费。
本研究旨在描述基于网络的营养干预措施“乳制品athlon”的开发过程，该措施旨在使用IDEAS（构思、设计、评估和分享）框架促进家庭中的乳制品消费。此外，它还评估了基于网络平台的用户体验（UX）。
遵循IDEAS框架，通过人种学研究和访谈探索了家庭对乳制品消费的看法和信念。基于计划行为理论的行为改变技术被整合进来，以增强对乳制品摄入的态度和感知行为控制。这些技术经过了迭代设计、原型测试和改进。使用AttrakDiff问卷评估用户体验，将使用“乳制品athlon”的家庭与使用《加拿大食物指南》（CFG）的家庭进行比较。儿童和家长在平台展示后（PRE）以及使用8周后（POST）完成问卷。AttrakDiff在从-3到+3的量表上评估实用质量（PQ）、享乐刺激（HSQ）、享乐身份（HIQ）和吸引力维度（ATT），得分>1被认为是最佳的，0-1是可接受的，<0是次优的。
在2019年4月至2020年8月期间，遵循IDEAS框架开发了“乳制品athlon”，以增强家庭对乳制品消费的态度和感知控制。在29个家庭中进行了用户体验评估，结果显示，与参考平台（CFG）相比，“乳制品athlon”在评估前和评估后的得分均显著更高（P<.001）。尽管两个平台最初都被评为最佳，但使用后用户体验评分下降：“乳制品athlon”组从评估前（1.7，标准差0.6）降至评估后（1.4，标准差0.8）（平均差异为0.4，95%置信区间0.2-0.7；P=.002），CFG组从（1.4，标准差0.6）降至（0.9，标准差0.6）（平均差异=0.6，95%置信区间0.5-0.6；P<.001）。使用“乳制品athlon”后，儿童（n=45）对所有用户体验维度的评分均为最佳，实用质量（PQ）得分为1.4（标准差1.0），享乐刺激（HSQ）得分为1.6（标准差1.0），享乐身份（HIQ）得分为1.4（标准差1.1），吸引力维度（ATT）得分为1.7（标准差0.9）。家长（n=50）对大多数维度的评分也为最佳，实用质量（PQ）得分为1.2（标准差1.0），享乐身份（HIQ）得分为1.4（标准差0.8），吸引力维度（ATT）得分为1.6（标准差0.8）。然而，享乐刺激（HSQ）维度的评分略低，为0.9（标准差0.8），表明在成人刺激方面需要改进。
本研究强调了IDEAS框架在开发促进乳制品消费的网络干预措施方面的有效性。“乳制品athlon”平台的用户体验被评为最佳，尤其是在视觉吸引力方面，尽管在成人刺激维度上需要改进。未来的研究将评估其对乳制品消费、饮食质量和家庭健康状况的影响。
