Do pop-up notifications regarding smartphone use decrease screen time, phone checking behavior, and self-reported problematic smartphone use? Evidence from a two-month experimental study
Although associations between problematic smartphone use (PSU), or impaired functioning in different aspects of life due to excessive smartphone use, and psychopathology are well-established, the body of research including objectively measured smartphone use (OMSU) is relatively small. In addition, the majority of these studies relies on cross-sectional self-report data. The aim of the current study was to fill that gap.
