Overview
Young people with Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms are consistently more likely to struggle with problematic social media use and gaming — but the reasons behind this link remain poorly understood. This study tested one prominent explanation: that specific cognitive difficulties associated with ADHD (impulse control, sensitivity to reward, and difficulties with time perception) might drive the connection.
A sample of 111 emerging adults was brought into the University of Amsterdam laboratory. Participants completed both self-report questionnaires and computerised cognitive tasks, providing complementary perspectives on the same constructs.
What we found
The main hypothesis was not supported: cognitive deficits, as measured here, did not statistically mediate the ADHD–problematic digital media use relationship. ADHD symptoms still directly predicted problematic use even after accounting for all three cognitive pathways.
Exploratory analyses offered more nuanced findings:
- Hyperactivity/impulsivity was linked to problematic social media use partly via inhibitory control deficits and temporal processing difficulties, suggesting these mechanisms may be relevant specifically for this symptom dimension.
- Inhibitory control emerged as a possible shared factor, related to both ADHD symptoms and social media problems concurrently.
- Behavioural task measures showed no explanatory value, reinforcing a known methodological issue: self-report and lab-based measures of the same constructs often don't align.
Study design
Participants were 111 emerging adults (average age 21.2; 84% female) recruited at the University of Amsterdam. Data were collected in a single 30-minute lab session in April 2024. Participants completed questionnaires and three computerised tasks in randomised order. Self-report measures included the ASRS (ADHD symptoms), SMDS (social media use), IGDS (gaming), and measures of inhibitory control, reward sensitivity, and temporal processing. Behavioural tasks included a stop-signal task, a delay discounting task, and a duration discrimination task. The study was approved by the Ethics Review Board of the Faculty of Social and Behavioural Sciences at the University of Amsterdam (FMG-7155_2024) and preregistered at AsPredicted.org.
What this means
Cognitive deficits alone appear insufficient to explain why ADHD symptoms translate into problematic digital media use. The full picture likely involves additional factors, including affective states and the specific reward structures built into social media platforms. The divergence between self-report and behavioural measures is also notable: tasks designed to assess impulse control or time perception in the lab may not reflect the same processes relevant to everyday social media behaviour. Future research could consider more ecologically valid measures, such as tasks incorporating social media cues.
