CONCLUSION

The current study provided empirical evidence to increase our understanding of smartphone addiction. We found that young adolescents in risk of smartphone addiction show more severe levels of behavioral and emotional problems, lower self-esteem and poorer quality of communication with their parents compared to those in normal risk.

Particularly we found association between smartphone addiction and aggressive behavior and self-esteem. We emphasize the importance of continued research not only in the area of smartphone, but also in other areas of information technology. Further exploratory and confirmatory studies should consider different sites, demographics, technological mobile devices/platforms, and applications.

청소년들의 스마트폰 중독과 연관된 심리적인 요인에 대한 고찰

스마트폰은 첨단 정보기술(IT)의 혁신적인 제품이지만, 청소년들을 특히 중독 위험에 빠뜨리는 위험성이 있다. 본 연구의 목적은 중학생들에서 스마트폰 중독 고위험군의 유병률을 확인하고 스마트폰 중독과 관련된 심리적인 요인들을 살펴보고자 한다. 총 490 명의 중학생들이 스마트폰 중독, 행동 및 정서 문제, 자존감, 불안감, 부모와의 의사소통의 정도를 측정하는 자가설문지를 작성하였다.

128(26.61%)의 중학생들이 스마트폰 중독 고위험군에 해당하는 것으로

밝혀졌다. 스마트폰 중독 고위험군에 속하는 중학생들은 정상대조군에 비해 행동 및 정서 문제가 더욱 심각하였으며, 자존감이 더 낮고, 부모와의 의사소통의 질이 낮다는 것을 알 수 있었다. 다중회귀분석을 통하여 스마트폰 중독과 공격적인 행동(β=0.593, t=3.825), ^{그리고 자존감(}(β=-0.305, t=-2.258)^과의 연관성을 확인할 수 있었다. 후속연구에서 스마트폰 중독과 인터넷 중독을 비롯한 여러 다양한 IT 매체의 중독에서 공통적으로 적용할 수 있는 생물학적, 혹은 심리적인 이론들에 대한 고찰이 제시되기를 기대한다.
