We investigate whether nudges can serve as in-the-moment support for youth online safety through a qualitative Wizard-of-Oz study with 19 adolescents (ages 13–19) using a realistic social media simulation (“SocialSim”). Even before nudges were introduced, participants demonstrated safety competence by interpreting social cues and using protective strategies. When nudges appeared, teens responded differently depending on risk severity and context; they relied on nudge guidance in high-risk, ambiguous situations (e.g., exposure to explicit content), while preferring to exercise their own judgement in lower-risk scenarios (e.g., information requests). We found that nudges were most effective when framed as developmental teaching moments that increased risk awareness and offered actionable advice while preserving autonomy. Participants emphasized proportionality, personalization, and trustworthy risk detection, and cautioned against overly restrictive interventions. Using a Social Information Processing (SIP) framework, this work informs the design of in-the-moment supports that foster adolescents’ decision-making, resilience, and self-regulation online.

As children progress through developmental stages, they undergo substantial biological, cognitive, and social changes, creating unique needs for online safety across different age groups (e.g., young children, tweens, teens). The existing parental control tools fail to account for these differences, leaving a notable gap in the literature on parental mediation. To this end, we conducted 10 focus group sessions with a total of 20 parents to understand their preferences for age-appropriate design components that promote self-regulation and open communication, followed by an ideation workshop with four UX design experts to translate these preferences into customized features. We then evaluated these designs (presented as storyboards) through semi-structured interviews with 25 parents. Our study joins the body of work on parental mediation, providing valuable insights into customizing parental control settings as children transition through the developmental stages. Based on our findings, we offer guidelines for future research in these directions.

Children from divorced households are granted access to devices (e.g., smartphones, tablets), helping them to maintain meaningful contact with both parents. However, regulating their device usage across two households presents unique co-parenting challenges, which are little studied in the existing literature on parental mediation. As we begin to address this gap, we used low-fidelity prototype designs, guided by the principles of fostering open communication and instilling self-regulation. We evaluated those designs (presented in the form of storyboards) through semi-structured interviews with 23 divorced parents, whose children are active Internet users and aged 13 years or below. Based on our analysis, we identified six distinct personas under four co-parenting types: conflicted, cooperative, parallel, and uninvolved. We then validated these personas through three focus group sessions with seven divorced parents. Within the context of these personas, we delve into diverse co-parenting challenges, shed light on the perceived benefits of the design in addressing those challenges, and outline design modifications suggested by parents to suit various co-parenting situations. The insights from our studies offer recommendations and guidelines for future research in the sphere of dynamic co-parenting.

Children with Autism Spectrum Disorder (ASD) often seek comfort from devices (e.g., smartphones) to deal with social overstimulation. However, such reliance exposes them to inappropriate digital content and increases susceptibility to mimicry and social vulnerability. Thus, parents having children with ASD encounter unique challenges in regulating their device usage, which are little addressed in the existing literature on parental mediation. As we begin to address this gap, we designed low-fidelity prototypes centered around open communication and self-regulation, which we refined based on the feedback from six ASD experts in two focus groups. We evaluated updated designs (presented in form of storyboards) through semi-structured interviews with 25 parents whose children with ASD (aged below 14) are active Internet users. Our study joins the body of work on parental mediation; our findings provide insights into inclusive parental control tools for children with ASD, and offer guidelines for future research in these directions.

Purpose The purpose of this study is to understand user perceptions and misconceptions regarding security tools. Security and privacy-preserving tools (for brevity, the authors term them as “security tools” in this paper, unless otherwise specified) are designed to protect the security and privacy of people in the digital environment. However, inappropriate use of these tools can lead to unexpected consequences that are preventable. Hence, it is significant to examine why users do not understand the security tools. Design/methodology/approach The authors conducted a qualitative study with 40 participants in the USA to investigate the prevalent misconceptions of people regarding security tools, their perceptions of data access and the corresponding impact on their usage behavior and data protection strategies. Findings While security vulnerabilities are often rooted in people’s internet usage behavior, this study examined user’s mental models of the internet and unpacked how the misconceptions about security tools relate to those mental models. Originality/value Based on the findings, this study offers recommendations highlighting the design aspects of security tools that need careful attention from researchers and industry practitioners, to alleviate users’ misconceptions and provide them with accurate conceptual models toward the desired use of security tools.

With access to devices and online platforms at an increasingly younger age, it is essential to protect children from potential online risks. In our studies, we particularly focused the parents who have a child under 13 years of age. To this end, deriving from developmental psychology, we base our low-fidelity prototype design (termed as 'treatment') on a set of design principles focusing on open communication, instilling self-regulation, and availing granularity along with designs of existing Google's parental control as a baseline. First, we conducted semi-structured interviews with 21 parents to understand their perceptions, including suggestions for design improvement within our prototype. Then, we conducted an online study over MTurk with 156 participants to compare and evaluate the treatment condition against the baseline in the realm of our design principles. As reflected in our results, parents appreciated the insights into the children's activities to have a meaningful discussion with them, the significance of nudges in instilling self-regulation, and the usefulness of granularity in a wide range of contexts, including shielding the children from inappropriate content and defining purpose-specific device usage. The findings from our studies lead to the recommendations, and the guideline for future research in the sphere of developmental parenting and inclusiveness.

Users share their personal devices with different entities in various circumstances. While prior research shed light on the broad reasons behind the sharing of mobile phones, there is a dearth of systematic study to understand the user's decision-making process and the underlying preferences and concerns in the context of phone sharing. To address these gaps, we designed a prototype that we leveraged to investigate the interplay between a user's relationship with sharees, preferences of sharing a subset of apps with a certain entity, perceived sensitivity of the apps being shared, and how these factors relate to their authentication behavior. We conducted a multi-session study with 50 participants from three countries (USA, Turkey, and Nepal), where the participants interacted with our prototype and took part in semi-structured interviews. The findings from our study revealed the need for phone sharing at a granular level, where we identified the factors that could influence a user's decision-making process in sharing. Our analysis unpacked the relation between a user's perceived sensitivity of apps being shared, and authentication behavior to protect information from unauthorized access. Overall, our findings advance the CSCW community's understanding of how the user attains a balance between privacy protection and the need for phone sharing.

With the growing adoption of digital technology in healthcare organizations, it is important to understand nursing professionals' behavior and challenges, and the corresponding privacy implications around digital technology use. To this end, we conducted semi-structured interviews with 21 participants (16 nursing professionals, and five nursing faculties) in the USA. In our study with nursing professionals, we explored how they used digital technology and protected sensitive health data at their workplace. We investigated their understanding of privacy breaches and possible consequences, the challenges they encountered to maintaining privacy, and their workarounds to deal with such issues. We looked into the support that professional nurses receive in the form of organizational training, and how they collaborate with the IT department at their institution to address technical issues. In addition, we shed light on the gap between their academic preparation and professional needs in the context of digital technology use and privacy protection, where we also interviewed five nursing faculties to get more in-depth understanding of this issue from the point of view of academia. Overall, our findings provide valuable insights for the CSCW community to better understand the challenges and privacy risks in digital technology use by nursing professionals, and lead to our recommendations to address these issues.
