論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025909

論文アブストラクト: Psychological distress in the form of depression, anxiety and other mental health challenges among college students is a growing health concern. Dearth of accurate, continuous, and multi-campus data on mental well-being presents significant challenges to intervention and mitigation efforts in college campuses. We examine the potential of social media as a new "barometer" for quantifying the mental well-being of college populations. Utilizing student-contributed data in Reddit communities of over 100 universities, we first build and evaluate a transfer learning based classification approach that can detect mental health expressions with 97% accuracy. Thereafter, we propose a robust campus-specific Mental Well-being Index: MWI. We find that MWI is able to reveal meaningful temporal patterns of mental well-being in campuses, and to assess how their expressions relate to university attributes like size, academic prestige, and student demographics. We discuss the implications of our work for improving counselor efforts, and in the design of tools that can enable better assessment of the mental health climate of college campuses.

When Fitness Meets Social Networks: Investigating Fitness Tracking and Social Practices on WeRun

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025654

論文アブストラクト: The last two decades have seen growing interest in promoting physical activities by using self-tracking technologies. Previous work has identified social interactions in self-tracking as a crucial factor in motivating users to exercise. However, it is unclear how integrating fitness features into complex pre-existing social network affects users' fitness tracking practices and social interactions. In this research, we address this gap through a qualitative study of 32 users of WeRun--a fitness plugin of the widely adopted Chinese mobile social networking service WeChat. Our findings indicate that sharing fitness data with pre-existing social networks motivates users to continue self-tracking and enhances their existing social relationships. Nevertheless, users' concerns about their online personal images lead to challenges around privacy. We discuss how our study could advance understanding of the effects of fitness applications built on top of pre-existing social networks. We present implications for future social fitness applications design.

"Be Grateful You Don't Have a Real Disease": Understanding Rare Disease Relationships

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025796

論文アブストラクト: We characterize how people with rare diseases consider their support needs as being met or neglected by different sources. After a 22-week study with 11 participants, we found that people with rare diseases identify strongly with their conditions but demonstrate a range of outlooks on their condition (positive, negative, and accepting). We found that participants think of themselves as being in a separate "Rare World" from the "normal" people in their lives and that relationships with friends and family members are strained. On the other hand, online communities were described as valuable sources of many forms of support, but do not adequately compensate for the lack of tangible support in offline relationships. We propose an approach to facilitating tangible support that leverages existing research on social matching, towards facilitating support among people with different rare diseases to overcome geographic and symptomatic challenges of coordinating support between people with the same rare disease.

When Personal Tracking Becomes Social: Examining the Use of Instagram for Healthy Eating

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025747

論文アブストラクト: Many people appropriate social media and online communities in their pursuit of personal health goals, such as healthy eating or increased physical activity. However, people struggle with impression management, and with reaching the right audiences when they share health information on these platforms. Instagram, a popular photo-based social media platform, has attracted many people who post and share their food photos. We aim to inform the design of tools to support healthy behaviors by understanding how people appropriate Instagram to track and share food data, the benefits they obtain from doing so, and the challenges they encounter. We interviewed 16 women who consistently record and share what they eat on Instagram. Participants tracked to support themselves and others in their pursuit of healthy eating goals. They sought social support for their own tracking and healthy behaviors and strove to provide that support for others. People adapted their personal tracking practices to better receive and give this support. Applying these results to the design of health tracking tools has the potential to help people better access social support.
