Data were collected from 101 undergraduate students (M_age = 20.04, SD_age = 4.02) at a Midwestern private university. Participants completed self-report measures of TikTok use and intensity (i.e., emotional attachment), resilience, perceived stress, and intrapersonal and interpersonal ER. Mediation and moderated mediation analyses were conducted using PROCESS macro models. Stress mediated the relationship between resilience and TikTok use but not intensity. Interpersonal ER moderated the resilience–stress link, with higher interpersonal ER amplifying the negative association between resilience and stress, which in turn was linked …
