    Abstract Background: Individuals with gaming disorder (GD) exhibit autonomic nervous system responses that indicate dysfunctional emotion regulation. Pulse rate variability (PRV) is a valuable biomarker for investigating the autonomic function of patients with mental disorders. Because individuals with GD dynamically regulate emotions during gaming, the PRV response relating to GD is not well understood. To investigate the dynamic PRV responses of individuals with GD, this study proposed the indexes of instantaneous PRV (iPRV) and instantaneous respiratory frequency (IF
    Results: A total of 32 college students without depressive and anxiety symptoms or cardiovascular diseases were recruited in this study. Participants were grouped into the high-risk GD and low-risk GD using both Chen Internet Addiction Scale and Internet Gaming Disorder Questionnaire. Their arterial blood pressures signals were measured while they watched gameplay videos with negative or positive emotional stimuli. Seven participants with high-risk GD exhibited significantly increased normalized VHF (nVHF) PRV and IF
    Conclusions: iPRV and IF

    Abstract The American Psychiatric Association has identified Internet gaming disorder (IGD) as a potential psychiatric disorder. Questionnaires are the main method to classify high-risk IGD (HIGD) and low-risk IGD (LIGD). However, the results obtained using questionnaires might be affected due to several factors. Flow can measure a person's state of concentration and cardiovascular signals can reflect the autonomic responses of a person. We propose to observe the cardiovascular responses and flow scores from the flow short scale of the HIGD and LIGD groups to assist questionnaires in IGD risk assessment. The preliminary study recruited 18 gamers from colleges. Games with the easy and hard levels were set to arouse desire for playing. The result showed that the flow scores of five HIGD participants were significantly lower compared with that of 13 LIGD participants. The stroke volume (SV) of the LIGD group during baseline (67.06 ± 11.61) was significantly greater that of (p < 0.05) while playing the easy game (64.08 ± 10.37) and playing the hard game (63.70 ± 9.89). For the LIGD group, the cardiac output (CO) during baseline (5.28 ± 0.97) was significantly greater (p < 0.01) than that of recovery (5.03 ± 0.83), and while playing the easy game (5.34 ± 0.98) it was significantly more than that during recovery (p < 0.05). For the HIGD group, a significant difference in the heart rate, SV, and CO was not observed. The changes in cardiovascular responses of the LIGD group are greater than that of the HIGD group. Gamers with LIGD might have a higher susceptibility to the negative effect of playing video games, but gamers with HIGD might not. The finding of this study might help psychologists to estimate the IGD risk.Clinical Relevance- This study investigated the differences in the score of flow short scale, self-assessment manikin, challenge/skill, emotional questionnaire, and the changes in the cardiovascular responses between the HIGD and LIGD groups.

    Abstract With the development of Internet, the number of people with symptoms of Internet gaming disorder (IGD) has increased. In the past, psychologists used retrospective questionnaires to diagnose IGD. However, it is difficult to diagnose IGD symptoms instantaneously using retrospective questionnaires due to the requirement of an Internet gaming experience of greater than 6 months and the limitations of retrospective memory. Observing the physiological regulation system might instantaneously diagnose IGD. However, observation of instantaneous physiological response is limited due to the lack of appropriate techniques. Our previous study successfully combined complimentary ensemble empirical mode decomposition and normalized direct quadrature to obtain respiratory instantaneous frequency (IF) to overcome this limitation. This study uses game-related films as stimulus materials to observe the difference in respiratory IF response per second of gamers with high-risk IGD (HIGD) and low-risk IGD (LIGD). The result showed that the respiratory IF of gamers with HIGD is lower than those of gamers with LIGD at the time of stimulation. In addition, the study also observes the dynamic change in respiratory IF per second (IF
