Everyday fragmentation through smartphone usage and affective well-being

Smartphone usage might interfere with and interrupt offline activities . These interruptions can be exogenous or endogenous . The resulting distraction and disengagement from the unmediated environment can pose a threat to affective well-being. So far, the focus in the literature on the effects of smartphone usage and well-being is on total time of usage or usage at specific times of the day (e.g., nighttime). However, we hypothesize that not necessarily longer periods of smartphone usage but the continuous small interruptions during daily life are detrimental to our affective well-being. We will combine smartphone sensing, experience sampling, and questionnaire data collected in the Smartphone Sensing Panel study (SSPS) to investigate this hypothesis on an inter- and intra-individual level. In this preregistration protocol, we specify diverse plausible operationalizations for both predictors and outcomes. We also preregister the multiverse of models we will build based on the variety of variables available. unknown other
