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. Study 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. The study was pre-registered in the Open Science Framework (OSF): https://osf.io/4duwh.

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. Data We collected data in three separate studies: Study to collect the vicarious experiences (part A). 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. Study to rate the vicarious experiences on perceived motivational impact and similarity (part B). 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. Study to evaluate the goal-setting dialog and the vicarious experiences therein (part C). 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).

Scheltinga、Eline Meijer及Willem-Paul Brinkman合著的论文《与虚拟教练设定体育活动目标：替代经验、个性化与接受度》（英文标题：Setting Physical Activity Goals with a Virtual Coach: Vicarious Experiences, Personalization and Acceptance）所涉及的数据与分析代码。该论文探讨了在虚拟教练（virtual coach）开展的体育活动目标设定对话中，个性化替代经验（vicarious experiences）的应用价值。 本研究基于2022年3月开展的一项实验，该实验成果为Beyza Hizli公开发表的硕士学位论文（http://resolver.tudelft.nl/uuid:b7225a91-6ae8-4a32-8441-38fb7ff74b4c）。在该实验中，39名英语流利的成年人与基于文本的虚拟教练Jody协作设定跑步或步行目标。参与者将被分配至两组之一：一组获得三项整体最具激励性的替代经验中的两项（即“通用”替代经验），另一组获得基于线性回归模型（linear regression model）筛选的“个性化”替代经验。在对话过程中，参与者需记录自身从所见他人案例中获得的启发；对话结束后，参与者还需填写其所设定目标类型（跑步或步行）相关的自我效能感（self-efficacy）评分、案例感知激励影响评分，以及关于所见案例中哪些内容具备激励性的自由文本回复（free-text response）。 本研究已在开放科学框架（Open Science Framework, OSF）完成预注册，链接为：https://osf.io/4duwh。 更多相关资源链接如下： 1. 虚拟教练Jody的实现代码可通过以下DOI链接获取：https://doi.org/10.5281/zenodo.6647381。 2. 本实验中使用的72条他人案例可在Beyza Hizli硕士学位论文的配套数据集中获取，链接为：https://doi.org/10.4121/20047328.v1。 3. 与虚拟教练对话的部分片段视频可通过以下链接观看：https://youtu.be/7WJy7-H3QEQ。 数据说明 我们通过三项独立研究完成数据采集： 1. 替代经验采集研究（研究A）：共征集72条替代经验，同时采集参与者的个体特征数据，包括年龄、参与体育活动的行为改变阶段等。 2. 替代经验评分研究（研究B）：邀请36名参与者分别对18条替代经验的感知激励影响以及与案例中人物的相似性进行评分，同时采集这36名参与者的个体特征数据。 3. 目标设定对话与替代经验评估研究（研究C）：39名参与者与基于文本的虚拟教练Jody交互以设定跑步或步行目标，参与者将看到个性化或通用的他人案例，我们同时采集了这39名参与者的个体特征数据。 如需了解我们采集的数据的更多细节，请参阅OSF预注册文档。此外，我们在“Data”文件夹内各数据文件的单独工作表中对各项测量指标进行了详细说明。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，以复现部分分析内容，链接为：https://doi.org/10.4121/20047328.v1。如有任何疑问，请联系Nele Albers（邮箱：[e-mail]）。
