This study aimed to examine the usage, acceptability, usability, perceived usefulness, and satisfaction of a web-based video-tailored physical activity (PA) intervention (TaylorActive) in adults.
In 2013-2014, 501 Australian adults aged 18+ years were randomized into a video-tailored intervention, text-tailored intervention, or control group. Over 3 months, the intervention groups received access to 8 sessions of personally tailored PA advice delivered via the TaylorActive website. Only the delivery method differed between the intervention groups: video-tailored vs. text-tailored. Google Analytics and telephone surveys conducted at post intervention (3 months) were used to assess intervention usage, acceptability, usability, perceived usefulness, and satisfaction. Quantitative and qualitative process data were analyzed using descriptive statistics and thematic content analysis.
Of 501 recruited adults, 259 completed the 3-month post-intervention survey (52% retention). Overall, usage of the TaylorActive website with respect to number of website visits, intervention sessions, and action plans completed was modest in both the video-tailored (7.6 ± 7.2 visits, mean ± SD) and text-tailored (7.3 ± 5.4 visits) groups with no significant between-group differences. The majority of participants in all groups used the TaylorActive website less than once in 2 weeks (66.7% video-tailored, 62.7% text-tailored, 87.5% control; p < 0.001). Acceptability was rated mostly high in all groups and, in some instances, significantly higher in the intervention groups compared to the control group (p < 0.010). Usability was also rated high; mean Systems Usability Scores were 77.3 (video-tailored), 75.7 (text-tailored), and 74.1 (control) with no significant between-group differences. Perceived usefulness of the TaylorActive intervention was low, though mostly rated higher in the intervention groups compared to the control group (p < 0.010). Satisfaction with the TaylorActive website was mixed. Participants in both intervention groups liked its ease of use, personalized feedback, and tracking of progress, but also found completing action plans and survey questions for each session repetitive and tedious.
Providing personally tailored PA advice on its own (through either video or text) is likely insufficient to ensure good retention, usage, perceived usefulness, and satisfaction with a web-based PA intervention. Strategies to address this may include the incorporation of additional intervention components such as activity trackers, social interactions, gamification, as well as the use of advanced artificial intelligence and machine learning technologies to allow more personalized dialogue with participants.
本研究旨在考察基于网络的视频定制体育活动（PA）干预措施（TaylorActive）在成年人中的使用情况、可接受性、可用性、感知有用性和满意度。
2013-2014 年，501 名澳大利亚 18 岁及以上成年人被随机分为视频定制干预组、文本定制干预组或对照组。在 3 个月内，干预组可访问 TaylorActive 网站上提供的 8 节个人定制的 PA 建议。干预组之间仅交付方法不同：视频定制与文本定制。在干预后（3 个月）进行 Google Analytics（谷歌分析）和电话调查，以评估干预措施的使用情况、可接受性、可用性、感知有用性和满意度。使用描述性统计和主题内容分析对定量和定性过程数据进行分析。
在招募的 501 名成年人中，有 259 名完成了 3 个月的干预后调查（保留率为 52%）。总体而言，视频定制（7.6 ± 7.2 次访问，平均值 ± 标准差）和文本定制（7.3 ± 5.4 次访问）组的 TaylorActive 网站使用量（网站访问次数、干预次数和行动计划完成情况）均适中，且两组间无显著差异。所有组中，大多数参与者在两周内使用 TaylorActive 网站的次数少于一次（视频定制组 66.7%，文本定制组 62.7%，对照组 87.5%；p < 0.001）。所有组的可接受性评价均较高，且某些情况下干预组的评价明显高于对照组（p < 0.010）。可用性也被评为较高；系统可用性得分平均值为 77.3（视频定制组）、75.7（文本定制组）和 74.1（对照组），且组间无显著差异。TaylorActive 干预措施的感知有用性较低，但与对照组相比，干预组的评价大多较高（p < 0.010）。对 TaylorActive 网站的满意度参差不齐。两个干预组的参与者都喜欢其易用性、个性化反馈和进度跟踪，但也发现完成每个会话的行动计划和调查问题重复且乏味。
仅提供个人定制的 PA 建议（通过视频或文本）可能不足以确保基于网络的 PA 干预措施的良好保留、使用、感知有用性和满意度。解决此问题的策略可能包括纳入其他干预措施，例如活动跟踪器、社交互动、游戏化，以及使用先进的人工智能和机器学习技术，以允许与参与者进行更个性化的对话。
