Mobile Data Collection - Incentive Experiment

The goal of this study was to experimentally measure the influence of different incentive schemes on the willingness to participate in passive mobile data collection among German smartphone owners. The data come from a web survey among German smartphone users 18 years and older who were recruited from a German nonprobability online panel. In December 2017, 1,214 respondents completed a questionnaire on smartphone use and skills, privacy and security concerns, general attitudes towards survey research and research institutions. In addition, the questionnaire included an experiment on the willingness to participate in mobile data collection under different incentive conditions. Topics: Ownership of smartphone, cell phone, desktop or laptop computer, tablet computer, and/or e-book reader; type of smartphone; willingness to participate in mobile data collection under different incentive conditions; likelihood of downloading the app to particiapte in this research study; respondent would rather participate in the study if he could receive 100 euros; total amount to be earned for the respondent ot participate in the study (open answer); reason why the respondent wouldn´t participate in the research study; willlingness to participate in the study for an incentive of 60 euros in total; willingness to activate different functions when downloading the app (interaction history, smartphone usage, charateristics of the social network, network quality and location information, activity data); previous invitation for research app download; research app download; frequency of smartphone use; smartphone activities (browsing, e-mails, taking pictures, view/ post social media content, shopping, online banking, installing apps, using GPS-enabled apps, connecting via Bluethooth, playing games, stream music/ videos); self-assessment of smartphone skills; attitude towards surveys and participaton at research studies (personal interest, waste of time, sales pitch, interesting experience, useful); trust in institutions regarding data privacy (market research companies, university researchers, government authorities such as the Federal Statistical Office, mobile service provider, app companies, credit card companies, online retailer, and social media platforms); general privacy concern; feeling of privacy violation by banks and credit card companies, tax authorities, government agencies, market research, social networks, apps, and internet browsers; concern regarding data security with smartphone activities for research purposes (online survey, survey apps, research apps, SMS survey, camera, activity data, GPS location, Bluetooth). Demography: sex, age; federal state; highest level of school education; highest level of vocational education. Additionally coded was: running number; duration (response time in seconds); device type used to fill out the questionnaire.本研究旨在通过实验量化不同激励方案对德国智能手机用户参与被动移动数据收集（passive mobile data collection）意愿的影响。本次研究数据来源于针对德国18岁及以上智能手机用户的网络调查，样本招募自德国无概率在线面板（nonprobability online panel）。2017年12月，共计1214名受访者完成了涵盖智能手机使用与技能、隐私与安全顾虑、对调查研究及科研机构总体态度的问卷。此外，问卷中还设置了一项实验，用于探究不同激励条件下受访者参与移动数据收集的意愿。 本次调查涉及的主题包括：智能手机、手机、台式机/笔记本电脑、平板电脑及/或电子书阅读器的拥有情况；智能手机型号；不同激励条件下参与移动数据收集的意愿；下载本研究相关应用程序（app）的可能性；若可获得100欧元报酬，受访者更愿意参与本研究；受访者参与本研究可获得的总报酬（开放式问题）；受访者不愿参与本研究的原因；总报酬为60欧元时的参与意愿；下载应用程序时愿意启用的不同功能（交互历史、智能手机使用情况、社交网络特征、网络质量与位置信息、活动数据）；过往参与研究类应用下载的邀请情况；研究类应用下载情况；智能手机使用频率；智能手机使用行为（浏览网页、收发电子邮件、拍摄照片、查看/发布社交媒体内容、购物、网上银行、安装应用程序、使用支持全球定位系统（GPS）的应用程序、通过蓝牙连接、玩游戏、流媒体播放音乐/视频）；智能手机技能自评；对调查及参与研究的态度（个人兴趣、浪费时间、推销手段、有趣体验、实用价值）；对各机构的数据隐私信任度（市场调研公司、大学科研人员、联邦统计局等政府部门、移动服务提供商、应用程序公司、信用卡公司、在线零售商以及社交媒体平台）；总体隐私顾虑；银行与信用卡公司、税务机关、政府机构、市场调研机构、社交网络、应用程序以及互联网浏览器引发的隐私侵犯感；针对研究用途的智能手机活动（在线调查、调查应用程序、研究类应用程序、短信调查、摄像头、活动数据、GPS位置、蓝牙）的数据安全顾虑。 人口统计学变量包括：性别、年龄；联邦州；最高学历；最高职业教育水平。 额外编码字段包括：流水号；作答时长（单位：秒）；填写问卷时使用的设备类型。
