한국 청소년의 인터넷 게임 중독과 음주, 흡연군의 성격, 기질 특성 비교

Different Personality Profiles among Internet Game Addiction, Alcohol Use, and Smoking Behavior in Korean Adolescent Sample

Objectives：The purpose of this study was to investigate the differences of the personality profiles between internet game addictor and substance abuser in the Korean high school students. Subjects & Methods：Subjects were 482 high school students (male/female=245/237) who resided in Korean urban area. All subjects completed the questionnaire asking the history of alcohol or smoking abuse, Internet Game Addiction Test (IGAT). and Temperament Character Inventory (TCI). IGAT for the Koreans was revised from the Young’s Internet Addiction Test. When subjects checked “yes” in more than 10 items of IGAT, they were labeled as “risk group”, and when less than 10, they were labeled as “non-risk group”. Results： Compared to non-risk group for the internet game addiction, risk group showed statistically significant higher ‘harm avoidance’, lower ‘reward dependence’, higher ‘self-transcendence’, lower ‘self-directedness’ and lower ‘cooperativeness’. Meanwhile, subjects who have abused alcohol or tobacco had higher ‘novelty seeking’ and lower ‘harm avoidance’ than nonusers. Conclulsion：The present results indicate the possibility that pathophysiology of behavior addiction such as internet game, in Korean adolescents, may be different from that of alcohol and smoking abuse
