摘要: Abstract Although associations between problematic smartphone use (PSU), or impaired functioning in different aspects of life due to excessive use, and psychopathology are well-established, the body research including objectively measured (OMSU) is relatively small. In addition, majority these studies relies on cross-sectional self-report data. Finally, there no investigating effect related notifications self-reported PSU OMSU. The aim current study was fill that gap. effective sample comprised 73 people (age M = 26.5, SD = 8.5; 82% women) who were randomly assigned into one three groups: control, active experimental, passive experimental. All groups filled out a measure at Time 1. Then, experimental group used tracking application for weeks. After receiving their data, received instructions setting up app so it would prompt based personal patterns next month while continued without prompting (Time 2). all participants asked about again 3). Contrary our expectations, regarding did not lower PSU, nor participants’ screen time frequency phone-checking behavior.
