Design outcomes

Primary

Measure	Time frame
It will be investigated whether and to what extent the variables of smartphone use (time, addiction) change up to the past measurement point (four weeks after the interaction). Smartphone use time is measured by the question "How much time do you spend daily on smartphone use?" Smartphone addiction will be assessed with the modified version of the Bergen Social Media Addiction Scale (BSMAS; Brailovskaia et al., 2022) for smartphone use.	—
