Background and Objectives: Internet addiction is an increasing problem in Korea. The previous studies in this area have targeted adolescents and young adults. This study was conducted to examine the risk of internet addiction in Korean adults and the effect of internet addiction on circadian rhythm. Materials and Methods: For this study, 508 subjects were chosen through population proportional sampling to represent the adult population in Korea, 325 of whom were included based on the Alcohol Use Disorder Identification Test-Korea (Audit-K), Zung's Self-Rating Depression Scale (SDS), drug use in the past year, and suicide attempts. In these subjects, sociodemographic factors including age, gender, and residential area were analyzed, and Young's Internet Addiction Scale (IAS), Morningness-Eveningness Questionnaire (MEQ), and an online survey examining sleep onset time on weekdays and weekends, wake-up time, and caffeinated drink intake were executed. Results: Of the 325 subjects, 136 (41.8%) belonged to a high-risk internet addiction group ($IAS{\geq}40$), and 189 (58.2%) belonged to a normal group (IAS < 40). There was a high proportion of male subjects (p = 0.03) in the high-risk group compared to the normal group. There was a high proportion of younger subjects (p = 0.055) in the high-risk group compared to the normal group, but this difference was not statistically significant. Compared to the normal group, there was a high proportion of the evening type ($MEQ{\leq}41$) in the high-risk group (p = 0.024), who also showed a high proportion of caffeinated drink intake (p < 0.001). Also, the high-risk group was found to go to bed and wake up late, but there was no statistically significant difference with the normal group. Conclusion: This study showed that many adults have a high-risk of internet addiction, and there was a significant correlation between internet addiction and sleep in adult, as has been found in adolescents and early adults. In the future, a longitudinal study will be needed to verify the causal relationship between internet addiction and morningness-eveningness.

본 연구는 청소년의 인터넷 중독에 대한 문제를 이해하기 위한 새로운 접근방법을 소개하고 있다. 기존 연구의 대부분은 인터넷과 온라인 게임 자체에 집중하여 청소년의 행동을 조절하기 위한 제도적, 기술적 방법을 소개하였다. 이러한 접근방법은 본질적인 청소년 사이버 문화에 대한 이해가 결여되어 단기적인 성과는 거둘 수 있지만 장기적이고 거시적인 관점에서 문제를 해소하기에는 제한적이다. 본 연구에서는 청소년의 정체성 성립과정과 자극과 반응 모델, 관계질서 모델 등을 통하여 본질적인 인터넷 중독 해소를 위한 접근방법을 제안하고자 한다. 본 연구의 결과물은 향후 지속될 실증적 연구에 토대가 될 것이며 청소년의 인터넷 중독 예방 활동을 위한 자료로 활용될 수 있을 것이다.

The eight-session program was performed on students categorized into the high risk group for about three weeks(three times a week). After the completion of the program, the students took a self-test and the changes of the scores were analyzed. Furthermore, qualitative analysis was performed on counseling process to compensate for the reliability reduction posed by limited sampling. This study can be summarized as follows. First, the symptoms of teen Internet addiction were alleviated. The effectiveness of the application of the program was verified by the fact that all the subjects were categorized into the general user group from the high risk group.

본 논문의 목적은 초등학생들의 커뮤니티 프로그램 사용 빈도가 인터넷 중독에 미치는 영향을 파악하는 것이다. 본 논문은 초등학교 5, 6학년 학생들을 대상으로 각종 커뮤니티 프로그램의 사용 빈도를 조사하고 그 결과에 따라 커뮤니티 프로그램 사용 빈도가 비교적 적은 집단과 사용 빈도가 많은 집단을 나누어 정보통신윤리 의식 및 인터넷 중독 진단에 많이 사용되는 K-척도를 활용하여 진단을 시행한 후 결과를 분석하였다. 연구 결과, 커뮤니티 프로그램 사용 빈도가 많을 수 록 인터넷 중독 위험성이 큰 것으로 나타났다. 또래집단과의 원활한 커뮤니케이션과 정보 공유 등에 좋은 영향을 미치는 커뮤니티 프로그램이지만 적지 않은 시간을 할애하고 집중함으로써 인터넷 중독의 위험에 빠질 수 있음을 알고 이에 대한 대책을 마련해야 할 것으로 판단된다.
