To Nudge or Not to Nudge: Co-Designing and Evaluating the Effectiveness of Adolescent Online Safety Nudges

There is growing concern regarding adolescent online risks posed by social media. Prior work calls for a paradigm shift from restrictive approaches towards strength-based solutions to online safety, that provide autonomy and control to teens. To better understand how we might design online safety interventions that help teens deal with online risks, we must include teens as partners in the design and evaluation of online safety solutions. To address this gap, my first dissertation study focused on co-designing online safety features with teens, which showed that teens often design real-time interventions that resemble "nudges". Therefore, my dissertation focuses on evaluating the effectiveness of these nudge designs in an ecologically valid social media simulation. To do this, I will conduct three studies: 1) a User Experience Bootcamp with teens to teach them design skills for co-designing online safety features, 2) a focus group study to design an ecologically valid social media simulation, 3) a between-subjects experiment within a social media simulation for evaluating the effect of nudges in educating teens and helping them make safer choices when exposed to risk. My goal for this research is to understand, design, develop, and evaluate online safety nudges that can help promote self-regulated, autonomous, and safer interactions for teens online.
