摘要

Concerns about the accuracy of self-reported screen time persist due to discrepancies with objective measures. This study compared passive smartphone tracking via the “Effortless Assessment of Risk States’’ (EARS) app with self-reported screen time from 495 adolescents. Based on self-reports, 94.26% of social media use occurred on smartphones. EARS-recorded social media use was higher (1.64 ± 1.93 h) than past-year self-report (1.44 ± 1.97 h; p = 0.037) but similar to post-sensing self-report (1.63 ± 1.93 h; p = 0.835). Higher picture vocabulary scores were associated with lower odds of under-reporting social media use (OR = 0.96, 95% CI: 0.93–0.99). Both self-reported (β = 0.06, 95% CI: 0.01–0.11) and EARS (β = 0.07, 95% CI: 0.03–0.12) measures correlated with externalizing symptoms. They were also correlated with social media addiction (self-reported:β = 0.15, 95% CI: 0.10–0.20; EARS:β = 0.06, 95% CI: 0.01–0.11). However, past-year self-report uniquely correlated with internalizing symptoms (β = 0.05, 95% CI: 0.01–0.09) and video game addiction (β = 0.05, 95% CI: 0.01–0.10). These findings highlight the value of integrating self-report and objective measures in screen media use research.
