Traditional online safety technologies often overly restrict teens and invade their privacy, while parents often lack knowledge regarding their digital privacy. As such, prior researchers have called for more collaborative approaches on adolescent online safety and networked privacy. In this paper, we propose family-centered approaches to foster parent-teen collaboration in ensuring their mobile privacy and online safety while respecting individual privacy, to enhance open discussion and teens' self-regulation. However, challenges such as power imbalances and conflicts with family values arise when implementing such approaches, making parent-teen collaboration difficult. Therefore, attending the family-centered design workshop provided an invaluable opportunity for us to discuss these challenges and identify best research practices for the future of collaborative online safety and privacy within families. 

We conducted a study with 173 adolescents (ages 13-21), who self-reported their offline and online risk experiences and uploaded their Instagram data to our study website to flag private conversations as unsafe. Risk profiles were first created based on the survey data and then compared with the risk-flagged social media data. Five risk profiles emerged: Low Risks (51% of the participants), Medium Risks (29%), Increased Sexting (8%), Increased Self-Harm (8%), and High Risk Perpetration (4%). Overall, the profiles correlated well with the social media data with the highest level of risk occurring in the three smallest profiles. Youth who experienced increased sexting and self-harm frequently reported engaging in unsafe sexual conversations. Meanwhile, high risk perpetration was characterized by increased violence, threats, and sales/promotion of illegal activities. A key insight from our study was that offline risk behavior sometimes manifested differently in online contexts (i.e., offline self-harm as risky online sexual interactions). Our findings highlight the need for targeted risk prevention strategies for youth online safety. 

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. 

Adolescent online safety research has largely focused on designing interventions for teens, with few evaluations that provide effective online safety solutions. It is challenging to evaluate such solutions without simulating an environment that mimics teens online risks. To overcome this gap, we conducted focus groups with 14 teens to co-design realistic online risk scenarios and their associated user personas, which can be implemented for an ecologically valid evaluation of interventions. We found that teens considered the characteristics of the risky user to be important and designed personas to have traits that align with the risk type, were more believable and authentic, and attracted teens through materialistic content. Teens also redesigned the risky scenarios to be subtle in information breaching, harsher in cyberbullying, and convincing in tricking the teen. Overall, this work provides an in-depth understanding of the types of bad actors and risky scenarios teens design for realistic research experimentation. 

Adolescent online safety researchers have emphasized the importance of moving beyond restrictive and privacy invasive approaches to online safety, towards resilience-based approaches for empowering teens to deal with online risks independently. Unfortunately, many of the existing online safety interventions are focused on parental mediation and not contextualized to teens' personal experiences online; thus, they do not effectively cater to the unique needs of teens. To better understand how we might design online safety interventions that help teens deal with online risks, as well as when and how to intervene, we must include teens as partners in the design process and equip them with the skills needed to contribute equally to the design process. As such, we conducted User Experience (UX) bootcamps with 21 teens (ages 13-17) to first teach them important UX design skills using industry standard tools, so they could create storyboards for unsafe online interactions commonly experienced by teens and high-fidelity, interactive prototypes for dealing with these situations. Based on their storyboards, teens often encountered information breaches and sexual risks with strangers, as well as cyberbullying from acquaintances or friends. While teens often blocked or reported strangers, they struggled with responding to risks from friends or acquaintances, seeking advice from others on the best action to take. Importantly, teens did not find any of the existing ways for responding to these risks to be effective in keeping them safe. When asked to create their own design-based interventions, teens frequently envisioned nudges that occurred in real-time. Interestingly, teens more often designed for risk prevention (rather than risk coping) by focusing on nudging the risk perpetrator (rather than the victim) to rethink their actions, block harmful actions from occurring, or penalizing perpetrators for inappropriate behavior to prevent it from happening again in the future. Teens also designed personalized sensitivity filters to provide teens the ability to manage content they wanted to see online. Some teens also designed personalized nudges, so that teens could receive intelligent, guided advice from the platform that would help them know how to handle online risks themselves without intervention from their parents. Our findings highlight how teens want to address online risks at the root by putting the onus of risk prevention on those who perpetrate them - rather than on the victim. Our work is the first to leverage co-design with teens to develop novel online safety interventions that advocate for a paradigm shift from youth risk protection to promoting good digital citizenship. 

Online sexual risks pose a serious and frequent threat to adolescents’ online safety. While significant work is done within the HCI community to understand teens’ sexual experiences through public posts, we extend their research by qualitatively analyzing 156 private Instagram conversations flagged by 58 adolescents to understand the characteristics of sexual risks faced with strangers, acquaintances, and friends. We found that youth are often victimized by strangers through sexual solicitation/harassment as well as sexual spamming via text and visual media, which is often ignored by them. In contrast, adolescents’ played mixed roles with acquaintances, as they were often victims of sexual harassment, but sometimes engaged in sexting, or interacted by rejecting sexual requests from acquaintances. Lastly, adolescents were never recipients of sexual risks with their friends, as they mostly mutually participated in sexting or sexual spamming. Based on these results, we provide our insights and recommendations for future researchers. Trigger Warning: This paper contains explicit language and anonymized private sexual messages.

We conducted User Experience (UX) Bootcamps with teens (ages 13-17) to teach them important UX design skills and industry standard tools for co-designing effective online safety interventions or “nudges”. In the process, we asked teens to storyboard about their risky or uncomfortable experiences and design high-fidelity prototypes for online safety interventions that would help mitigate these negative experiences. 

The methods in which we study the online experiences of adolescents should be evidence-based and informed by youth. This is especially true when studying sensitive topics, such as the online risk behaviors of minors. We directly engaged 20 adolescents (ages 12-18) in the co-design of two different research methodologies (i.e., diary studies and analyzing social media trace data) for conducting adolescent online safety research. We also interviewed 13 of their parents to understand their perspectives. Overall, teens wanted to share their personal experiences and benefit society, while parents wanted researchers to tackle a topic that they felt was a prevalent problem for teens. Yet, they both had significant concerns regarding data privacy of the sensitive disclosures made by teens during such studies. Teens' feared getting in trouble. Participants emphasized the importance of developing a trusting relationship with the researcher to overcome these concerns. Participants also saw the potential for using the research study as a tool for risk-reporting and mitigation, where researchers could act as liaisons between the teens and other parties (e.g., counselors, law enforcement, parents) to share pertinent risk details and facilitate resources or even help teens directly by giving them strategies for mitigating online risks they encountered during the study. Our research delves into important ethical considerations for conducting risk-focused research with adolescents and uncovers the critical need for designing risk-based research for youth protection. We provide researchers with heuristic guidelines for conducting ethical research with vulnerable populations (i.e., adolescents) and keeping participants safe while doing so. 

Our limited knowledge about what teens do online and inability to protect them from harm evokes a sense of fear that makes us prone to “risk discourse.” However, this mindset overshadows the potential benefits of youth engaging online and constrains our ability to design online safety mechanisms that are developmentally appropriate for empowering adolescents to become resilient to risks. Our goal in attending this workshop is to find actionable ways to incorporate new asset-based practices that prioritize teens’ strengths and capacities to improve adolescent online safety. 

Future online safety technologies should consider the privacy needs of adolescents (ages 13-17) and support their ability to self-regulate their online behaviors and navigate online risks. To do this, adolescent online safety researchers and practitioners must shift towards solutions that are more teen-centric by designing privacy-preserving online safety solutions for teens. In this paper, we discuss privacy challenges we have encountered in conducting adolescent online safety research. We discuss privacy concerns of teens in regard to sharing their private social media data with researchers and potentially taking part in a user study where they share some of this information with their parents. Our research emphasizes a need for more privacy-preserving interventions for teens.
