A Randomized Controlled Ecological Momentary Intervention to Improve Digital Self-Regulation and Well-Being

The primary objective of this study is to examine whether an ecological momentary intervention (EMI), combining behavioral self-monitoring (screen time screenshot uploads) and structured reflection, can enhance metacognitive awareness and metacognitive regulation in the context of recreational screen time among young adults. A secondary objective is to investigate whether improvements in metacognitive processes are associated with subsequent changes in behavioral and psychological outcomes, including recreational screen time (RST), stress, and life satisfaction. Furthermore, this study aims to elucidate the underlying mechanisms through which the intervention exerts its effects by integrating a randomized controlled trial (RCT) design with intensive longitudinal (daily diary) data. Specifically, the study addresses the following research questions: RQ1 (Primary Intervention Effect on Metacognition): Does the EMI lead to higher levels of daily metacognitive awareness and metacognitive regulation (planning, monitoring, and evaluation) compared to the control group? RQ2 (Within-person Associations): At the within-person level, do day-to-day fluctuations in metacognitive awareness and regulation predict same-day and next-day changes in recreational screen time, stress, and life satisfaction? RQ3 (Mediating Mechanism): Do increases in metacognitive awareness and regulation mediate the effects of the EMI on recreational screen time, stress, and life satisfaction? RQ4 (Between-p…
