Abstract

This study analyzed the correlation between adolescents' smartphone addiction as well as depression, self-esteem, and self-regulation based on QEEG (Quantitative Electroencephalogram) analysis. The study period was from March 19 to July 12, 2019, and the subjects were 76 students at P Middle School in Gyeonggi-do (normal group 47, risk group 29) who filled out a questionnaire and were subjected to quantitative EEG. The data analysis was performed via frequency analysis, independent t-test, correlation analysis, and path analysis of the IBM SPSS Statics 21.0 program. First, smartphone addiction had a positive correlation with depression. Second, smartphone addiction showed a negative correlation with self-esteem and α wave. Third, depression showed a negative correlation with self-esteem, which did not show a significant correlation with self-regulation. Fourth, depression was higher in the risk group than the normal group. For self-esteem, the normal group scored higher than the risk group. Self-regulation showed higher significant differences with the normal group than the risk group. Fifth, for α wave and SMR, the normal group scored higher than the risk group. Sixth, α waves had a negative effect on smartphone addiction. This study is meaningful in that it applied a brain science approach using quantitative analysis for objective evaluation of smartphone addiction.

본 연구는 청소년의 스마트폰 중독과 우울, 자아존중감 및 자기조절력의 상관관계를 정량 뇌파 분석을 통해 규명하고자 시행되었다. 연구기간은 2019년 3월 19일부터 7월 12일까지였으며, 경기도 P 중학교에서 일반군 47명, 스마트폰 중독 주의위험군 29명을 대상으로 구조화된 설문지와 정량 뇌파를 활용하여 측정한 자기조절력 자료 76부를 분석하였다. 자료는 IBM SPSS/WIN 21.0 프로그램을 활용, 빈도분석 및 독립-t 검증, 상관관계분석, 경로분석을 실시하였다. 분석 결과를 요약하면 다음과 같다. 첫째, 스마트폰 중독은 우울에 정의 상관관계를 보였다. 둘째, 스마트폰 중독은 자아 존중감 및 α파와 부의 상관관계를 보였다. 셋째, 우울은 자아존중감과 부의 상관관계를 보였고, 자아존중감은 자기 조절력과 유의한 상관관계가 나타나지 않았다. 넷째, 우울은 주의위험군이 일반군보다 높게 나타났고, 자아존중감은 일반군이 주의위험군보다 높았다. 자기 조절력은 일반군이 주의위험군보다 높게 나타나 모든 변수에서 집단 간 차이를 보였다. 다섯째, 자기조절력의 하위요인인 α파는 일반군이 주의위험군보다 높게, SMR도 일반군이 주의위험군보다 높게 나타났다. 여섯째, 경로분석 결과, α파가 스마트폰에 부적 영향을 미쳤다. 본 연구결과는 스마트폰 중독의 객관적 평가를 위해 정량화 분석을 활용한 뇌과학적 접근방법을 적용함으로써 상담과 교육 현장에서 스마트폰 중독의 예방을 위한 상담 프로그램 개선 및 개발의 근거를 제시하였다.
