dc.description.abstract | Objective This study evaluated the validity of self-reported smartphone usage data against objectively-measured smartphone usage data by directly tracking the activities in the participants' smartphone among Chinese adolescents and young adults in Hong Kong. Methods A total of 187 participants were recruited (mean age 19.4, 71.7% female) between 2017 and 2018. A smartphone usage tracking app was installed on all participants' smartphone for 7 consecutive days. After the 7-day monitoring period, they completed a selfadministered questionnaire on smartphone usage habits. Results Although the correlation between self-reported and objectively-measured total smartphone usage time was insignificant (rho=-0.10, p=0.18), in three out of the four usage domains were positively and significantly correlated, namely social network (rho=0.21, p=0.005), instant messaging (rho=0.27, p<0.001), and games (rho=0.64, p<0.001). Participants' self-report of the total time spent on smart phones exceeded the objective data by around 760 min per week (self-reported 1,930.3 min/wk vs. objectively-measured 1,170.7 min/ wk, p<0.001). Most of the over-reporting was contributed by the web browsing domain (self-reported 447.8 min/wk vs. objectively -measured 33.3 min/wk, p<0.001). Conclusion Our results showed large discrepancies between self-reported smartphone and objectively-measured smartphone usage except for self-reported usage on game apps.
