- What it's testing
- 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.
