Screen Time Questionnaire
Release 5.0 Data Table: nt_y_st
Measure Description: This measure includes customized questions about the overall amount of time that the youth spends using visual media on a typical weekday and weekend day. Media activities assessed include:
- Watching TV shows or movies
- Watching videos (such as YouTube)
- Playing video games (single- or multiplayer) on a computer, console, phone or other device
- Texting on a cell phone, tablet, or computer
- Visiting social media apps like Snapchat, Instagram, TikTok
- Video chat. Seven response options were: none, < 30 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, and 4+ hours.
See Modifications since initial administration regarding substantial changes made to this measure starting at the 2-year follow-up.
ABCD Subdomain: Screen Use
Number of Variables: 198
Summary Score(s): Yes
Measurement Waves Administered: Annually since Baseline
Modifications since initial administration: From the 2-year follow-up on, response options were changed to an open format of number of hours and minutes spent on each screen usage activity. We also included the 6-item social media addiction and video game addiction questionnaires adapted from the Bergen Facebook Addiction Scale (Andreassen et al, 2012). Additionally, we added customized questions about timing of screen usage around bedtime, mobile phone ownership and usage, social media accounts, and online dating. A summary of changes is contained in the table below.
