The Conceptual and Methodological Mayhem of “Screen Time”

TLDR

Screen‑time impact debates are widespread, yet existing studies are mixed and lack longitudinal evidence for causal or long‑term effects. The authors critically review shortcomings in screen‑time research and propose recommendations, including a user‑focused approach to examine affordances. They highlight poor conceptualisation, non‑standardised self‑report measures, and temporal/contextual measurement issues, and suggest distinguishing objective screen‑time metrics from subjective affordance experiences to better capture differential impacts.

Abstract

Debates concerning the impacts of screen time are widespread. Existing research presents mixed findings, and lacks longitudinal evidence for any causal or long-term effects. We present a critical account of the current shortcomings of the screen time literature. These include poor conceptualisation, the use of non-standardised measures that are predominantly self-report, and issues with measuring screen time over time and context. Based on these issues, we make a series of recommendations as a basis for furthering academic and public debate. These include drawing on a user-focused approach in order to seek the various affordances gained from "screen use". Within this, we can better understand the way in which these vary across time and context, and make distinction between objective measures of "screen time" compared to those more subjective experiences of uses or affordances, and the differential impacts these may bring.
