Situational boundary conditions of digital stress: Goal conflict and autonomy frustration make smartphone use more stressful
Permanent connectedness via smartphones can negatively affect users by eliciting stress. Past research focused on the stress-inducing potential of overt behaviours, such as communication load and media multitasking. The cognitive engagement with online interactions (online vigilance) has only recently received attention. Additionally, previous findings were inconsistent, suggesting that conditional effects may be at play. A preregistered experience sampling study (N = 130; 1,427 use episodes) investigated relationships of cognitive (online vigilance) and behavioural (communication load, media multitasking) smartphone use patterns with perceived stress and introduced two situational boundary conditions (goal conflict, autonomy need dissatisfaction). Results demonstrate the strong potential of the mental salience of online interactions to induce stress. By increasing communication load, online vigilance indirectly predicted stress. Goal conflict and autonomy need dissatisfaction moderated the influence of online vigilance and media multitasking on perceived stress. Findings are discussed in the context of social pressures and self-control of smartphone use.
