Previous research has shown that problematic smartphone use (PSU) is related to several affect-related psychopathology variables. Emotion dysregulation has been regarded as a central psychological factor associated with that type of psychopathology. In this paper, the association between expressive emotional suppression, a form of emotion dysregulation, with PSU was investigated. Furthermore, we tested if types of smartphone use (process and social use) mediated that association.
Problematic smartphone use (PSU) is associated with several types of psychopathology, such as depression and anxiety severity. However, the majority of studies reporting these associations have not used objective smartphone use data and/or repeated-measures study design. Our aim was to investigate how self-reported levels of PSU, depression, anxiety, and daily depressive mood relate to objectively measured smartphone use over one week.
