Setting Physical Activity Goals with a Virtual Coach: Data and Analysis Code

This is the data and analysis code underlying the paper "Setting Physical Activity Goals with a Virtual Coach: Vicarious Experiences, Personalization and Acceptance" by Nele Albers, Beyza Hizli, Bouke L. Scheltinga, Eline Meijer, and Willem-Paul Brinkman. The paper examines the use of personalized vicarious experiences in a goal-setting dialog for physical activity with a virtual coach. <br> <strong>Study</strong> The paper is based on the study conducted in March 2022 for the publicly available Master's thesis by Beyza Hizli (http://resolver.tudelft.nl/uuid:b7225a91-6ae8-4a32-8441-38fb7ff74b4c). In this study, 39 fluently English-speaking adults set a running or walking goal with the text-based virtual coach Jody. Participants thereby received either two of the three overall most motivating vicarious experiences (i.e., "generic" experiences) or "personalized" vicarious experiences chosen based on a linear regression model. During the dialog, participants wrote what they could take away from the examples from other people that they saw. After the dialog, participants further provided information regarding their self-efficacy for the type of goal they set (i.e., running or walking), ratings of examples on perceived motivational impact, and a free-text response about what they found motivating about the examples they saw. <br> The study was pre-registered in the Open Science Framework (OSF): https://osf.io/4duwh. <br> Links to further resources: The implementation of the virtual coach Jody is available here: https://doi.org/10.5281/zenodo.6647381. The 72 examples from other people used in the study can be found in the dataset accompanying the Master's thesis by Beyza Hizli: https://doi.org/10.4121/20047328.v1. A video of part of the dialog with the virtual coach is available here: https://youtu.be/7WJy7-H3QEQ. <strong>Data</strong> We collected data in three separate studies: <strong>Study to collect the vicarious experiences (part A).</strong> We gathered the vicarious experiences together with data on individual characteristics of the participants (e.g., age, stage of change for becoming physically active). We collected vicarious experiences from 72 people. <strong>Study to rate the vicarious experiences on perceived motivational impact and similarity (part B).</strong> We asked 36 individuals to each rate 18 vicarious experiences on perceived motivational impact and similarity to the person in the experience. We further collected data on individual characteristics of these 36 participants. <strong>Study to evaluate the goal-setting dialog and the vicarious experiences therein (part C)</strong>. 39 participants interacted with the text-based virtual coach Jody to set a running or walking goal. Participants saw either personalized or generic examples from other people. We also collected data on individual characteristics of these 39 participants. Please refer to the OSF pre-registration for more information on the data we collected. In addition, we describe our measures in detail in a separate sheet in each data file in the "Data"-folder. Note that we do not provide all data here: we describe in our README-files which data needs to be downloaded from the repository accompanying the Master's thesis by Beyza Hizli to reproduce some of our analyses (https://doi.org/10.4121/20047328.v1). <br> If you have any questions, please contact Nele Albers ([e-mail]). <br>本数据集包含论文《借助虚拟教练设定身体活动目标：替代性体验、个性化设置与接受度》（*Setting Physical Activity Goals with a Virtual Coach: Vicarious Experiences, Personalization and Acceptance*）的支撑数据与分析代码，该论文作者为Nele Albers、Beyza Hizli、Bouke L. Scheltinga、Eline Meijer与Willem-Paul Brinkman。该论文探讨了在虚拟教练（virtual coach）参与的身体活动目标设定对话中，应用个性化替代性体验（vicarious experiences）的相关实践。 **研究** 本论文基于2022年3月开展的一项研究，该研究源自Beyza Hizli公开发布的硕士学位论文（链接：http://resolver.tudelft.nl/uuid:b7225a91-6ae8-4a32-8441-38fb7ff74b4c）。本研究共招募39名英语流利的成年人，参与者通过文本型虚拟教练Jody设定跑步或步行目标。参与者将收到三类总体最具激励性的替代性体验中的两种（即"通用型"体验），或是基于线性回归模型（linear regression model）筛选出的"个性化"替代性体验。对话过程中，参与者需写下自身从所见的他人案例中可获得的启发。对话结束后，参与者需进一步提供与自身设定目标类型（跑步或步行）相关的自我效能感（self-efficacy）信息、对案例感知激励效果的评分，以及关于自身认为哪些案例内容具备激励性的自由文本反馈。 本研究已在开放科学框架（Open Science Framework, OSF）进行预注册，链接为：https://osf.io/4duwh。 **补充资源链接** 虚拟教练Jody的实现代码可通过以下链接获取：https://doi.org/10.5281/zenodo.6647381。本研究使用的72份他人案例可在Beyza Hizli硕士学位论文配套的数据集中获取：https://doi.org/10.4121/20047328.v1。部分与虚拟教练的对话视频可通过以下链接查看：https://youtu.be/7WJy7-H3QEQ。 **数据说明** 本研究通过三项独立实验收集数据： **替代性体验收集实验（A部分）**：我们收集了替代性体验样本，同时记录了参与者的个体特征数据（如年龄、参与身体活动的行为改变阶段），本次实验共从72名受访者处获取相关样本。 **替代性体验评分实验（B部分）**：我们邀请36名受访者分别对18份替代性体验的感知激励效果及与案例中人物的相似性进行评分，同时收集了这36名参与者的个体特征数据。 **目标设定对话与替代性体验评估实验（C部分）**：39名参与者与文本型虚拟教练Jody互动，完成跑步或步行目标的设定。参与者将看到个性化或通用型的他人案例，我们同时收集了这39名参与者的个体特征数据。 如需了解本次收集数据的更多细节，请查阅OSF预注册页面。此外，我们在"数据"文件夹内各数据文件的单独工作表中详细说明了本次使用的测量指标。请注意，本数据集并未包含全部数据：我们在README文件中说明了需从Beyza Hizli硕士学位论文配套仓库中下载哪些数据，方可复现部分分析流程（链接：https://doi.org/10.4121/20047328.v1）。 如有任何疑问，请联系Nele Albers（邮箱：[e-mail]）。
