論文アブストラクト： Emotion- and stressed-related eating (ESRE) is associated with weight management difficulties and is more likely to affect women than men. Additionally, health information technology (HIT) for weight management tends to be less effective for women than it is for men, and less effective for people who engage in ESRE. Therefore, this study explores how HIT can support overweight/obese women curb ESRE behavior. Study participants, all adult overweight/obese women (BMI ' 25), logged dietary intake for 10 days with the Lose It! smartphone app as an elicitation exercise. Cross sectional, semi-structured interviews (N = 22) were then conducted to explore technology support needs concerning ESRE behavior. Findings revealed participants had the following needs: holistic health goal development, building motivation to achieve goals, and assistance with handling stress. Resulting HIT guidelines include supporting holistic health goals, developing and sustaining motivation, exchange of emotional support, understanding of behavior, and change in ESRE mindset.
論文アブストラクト： Mental wellness is a desirable health outcome for students. However, current personal informatics systems do not adequately support students in creating concrete mental health-related goals and turning them into actionable plans. In this paper, we introduce MindNavigator - a workshop in which groups of college students were invited to generate behavioral change goals to manage daily life stress and practice personalized interventions for two weeks. We describe the manner in which participants identified both stressors and pleasures to create actionable, engaging, and open-ended behavioral plans that aided in stress relief. We found that the social nature of the workshop helped participants understand themselves and execute self-intervention in new ways. Through this practice, we build on prior studies to propose an analytical framework of personal informatics for mental wellness.
論文アブストラクト： Emotions play a major role in how interpersonal conflicts unfold. Although several strategies and technological approaches have been proposed for emotion regulation, they often require conscious attention and effort. This often limits their efficacy in practice. In this paper, we propose a different approach inspired by self-perception theory: noticing that people are often reacting to the perception of their own behavior, we artificially change their perceptions to influence their emotions. We conducted two studies to evaluate the potential of this approach by automatically and subtly altering how people perceive their own voice. In one study, participants that received voice feedback with a calmer tone during relationship conflicts felt less anxious. In the other study, participants who listened to their own voices with a lower pitch during contentious debates felt more powerful. We discuss the implications of our findings and the opportunities for designing automatic and less perceptible emotion regulation systems.
論文アブストラクト： Many online communities cater to the critical and unmet needs of individuals challenged with mental illnesses. Generally, communities engender characteristic linguistic practices, known as norms. Conformance to these norms, or linguistic accommodation, encourages social approval and acceptance. This paper investigates whether linguistic accommodation impacts a specific social feedback: the support received by an individual in an online mental health community. We first quantitatively derive two measures for each post in these communities: 1) the linguistic accommodation it exhibits, and 2) the level of support it receives. Thereafter, we build a statistical framework to examine the relationship between these measures. Although the extent to which accommodation is associated with support varies, we find a positive link between the two, consistent across 55 Reddit communities serving various psychological needs. We discuss how our work surfaces a tension in the functioning of these sensitive communities, and present design implications for improving their support provisioning mechanisms.
