Non-social smartphone use mediates the relationship between intolerance of uncertainty and problematic smartphone use: Evidence from a repeated-measures study
The aim of the current work was to investigate relations between problematic smartphone use (PSU) severity and intolerance of uncertainty, a transdiagnostic psychopathology construct reflecting individual differences in reacting to uncertain situations and events. In addition, it was tested if use of social and/or non-social smartphone use mediated associations between intolerance of uncertainty and PSU.
