Key result
HRV after in-game events identifies video game addiction with ~70% accuracy.
Why the study?
The study was conducted to determine HRV parameters from ECGs that can quantitatively characterize game addiction.
Do heart rate variability parameters measured during gameplay accurately identify video game addiction?
Population
23 subjects (11 game-addicted and 12 non-addicted subjects)
Comparison
Game-addicted subjects vs non-addicted subjects
Follow-up

Do heart rate variability parameters measured during gameplay accurately identify video game addiction?
Effect estimate: Accuracy 69.3%-70.3%
Heart rate variability parameters measured after specific in-game events can identify video game addiction with moderate accuracy, serving as a potential objective diagnostic method.
Kim et al. (2021) conducted an observational in Video game addiction (n=23). Heart rate variability (HRV) parameters vs. Non-addicted subjects was evaluated on Accuracy in diagnosing addicted and non-addicted subjects (Accuracy 69.3%-70.3%). Heart rate variability parameters (pNNI20, RMSSD, and LF) measured after in-game events identified video game addiction with an accuracy of 69.3% to 70.3% (AUC 0.654-0.677).
