Emotional responses of internet gaming disorder by doing abdominal breathing

In 2013, the ninth criteria of Internet Gaming Disorder (IGD) were firstly laid out in the Diagnostic and Statistical Manual for Mental Disorders (DSM-V). It performed that playing online game became the most activity of Internet addiction (IA). In order to discriminate the high-risk IA with IGD (HIGD) and low-risk IA with nonIGD (LIGD), the abdominal breathing (AB) and the emotional Self-Assessment Manikin (SAM) questionnaire were used in this study. Totally 19 HIGD subjects and 21 LIGD subjects were asked to watch the three type films (film1, film2 and film3), and to reply SAM questionnaire before and after AB. The results showed the average (t-test) between the arousal scores in before and after AB for LIGD people under all films (p = .01) and film
₃
(p = .03). As well, the statically significant difference in distribution (F-test) between the valence scores for HIGD people and LIGD people under film
₂
(p = .04) and film
₃
(p = .03). To summarize our results, by doing AB, HIGD people mainly changed their emotional valence, and LIGD people mainly changed their emotional arousal for within study. For between study, the type of film
₂
can distinguish between HIGD and LIGD people, and AB cannot obvious calmed emotional valence for HIGD people. The valence and arousal scores are the potential indexes for discriminating HIGD and LIGD. AB might play a mediation of emotional responses for IGD subjects. The physiological responses for IGD people are going to be investigated in near future.
