TULAGA MA MANATU:
O tagata ei ai le initaneti (addiction) (IA) e mafatia mai faʻafitauli tau mafaufau, faaletino, agafesootai, ma galuega. IA aofia ai mafaufauga faʻapitoa i le mafaufau ma le physiological, ma i totonu o syndromes, o lagona na taua tele i le mafaufau ma le faʻavasegaga o le tino o IA. Ae ui i lea, e leʻi tele ni suʻesuʻega faʻale-tino o le IA na suʻesuʻeina. O le faʻaogaina o le tino (ANS) o se fesoʻotaʻiga lelei i le va o le IA ma lagona, ma le arrhythmia o le respiratory sinus (RSA) na maua mai i le ANS sa faʻamaonia e faatatau i le IA.
METHODS:
An emotional induction experiment using negative and positive emotional films was conducted to validate the hypotheses. Thirty-four participants recruited from college were classified into high-risk IA group (HIA) and low-risk IA group (LIA). The respiratory signals, ECG signals, and self-assessed emotional intensity were acquired. The relationship and difference between IA and RSA was tested using descriptive statistics and inferential statistics.
TULAFONO:
The RSA values of HIA were lower than those of LIA both before and after the induction of positive and negative emotions. When participants experienced a negative emotion (anger or fear), their RSA values declined; the decline for HIA was greater than that for LIA. The RSA values of HIA participants before induction of fear, happiness, or surprise, statistically significantly differed from that after induction of those emotions, with p values of 0.007, 0.04 and 0.01 respectively. The difference between the changes in RSA values upon the induction of surprise of HIA and LIA was statistically significant difference (p = 0.03). The interaction between two IA groups among emotional induction states was statistically significant difference.
FAAIUGA:
RSA value here was the main variable that reflected ANS activity, and especially vagus nerve regulation. The results revealed that the changes in RSA values were biologically significantly different between HIA and LIA, especially when sadness, happiness, or surprise was induced. HIA people exhibited stronger RSA reactivity following negative emotion than LIA people, but the RSA reactivity following positive emotion was weaker. This study provides more physiological information about IA and assists further investigation on the regulation of the ANS for IA abusers. The results will benefit the further application, early detection, therapy, and even early prevention. Clinical trial registration details This study was approved by the Institution Review Board of the National Taiwan University Hospital, Hsinchu Branch (Hsinchu, Taiwan), under the research project: A study of interactions between cognition, emotion and physiology (contract no.100IRB-32).
