Abstract: In the digital age, social networking sites (SNS) have become deeply embedded in the fabric of everyday life, offering substantial social, informational, and emotional benefits. However, growing concerns about excessive and compulsive use have brought to light the darker side of these platforms, particularly their impact on mental health and overall well-being. Amid rising calls for more mindful technology use, SNS use reduction has emerged as a promising yet underexamined strategy for mitigating the harms associated with hedonic information systems (IS). This work seeks to advance a nuanced understanding of the SNS use reduction process by drawing on multiple theoretical lenses and methodological approaches. It begins with a systematic literature review, synthesizing the fragmented body of knowledge surrounding hedonic IS use reduction and identifying key gaps in theory and practice. Building on this foundation, the research adopts a cognitive-affective framework to examine how individuals' emotional responses and rational evaluations jointly influence the motivation to reduce SNS engagement. Incorporating a risk- and fear-based perspective, the thesis further unpacks the complex interplay between contextual triggers (e.g., perceived vulnerability), organic responses (e.g., fear of adverse consequences), behavior response and the consequence of reduced use. A mixed-methods study highlights the role of distractions- both internal and external to SNS - as mechanisms that inadvertently impact the disengagement process. Additionally, this work explores how a neurodiversity condition - attention deficit hyperactivity disorder (ADHD) - poses unique challenges to use reduction, particularly through impaired self-regulation and time management capacities. Collectively, the five studies presented in this thesis illuminate the multifaceted nature of SNS use reduction, revealing it as a dynamic process shaped by psychological, contextual, and cognitive-behavioral dimensions. The findings not only deepen theoretical insight into IS self-regulation but also inform practical interventions aimed at promoting healthier relationships with technology. Ultimately, this work contributes to ongoing efforts to foster more intentional and balanced digital engagement in a hyperconnected world.
