대학생의 실존적 공허와 경험회피가 스마트폰 과의존에 미치는 영향 : 적응적 인지적 정서조절전략의 조절된 매개효과 = The Effect of College Students' Existential Vacuum on Smartphone Overuse: The Mediation Effect of Experiential Avoidance and the Moderated Mediation Effect of Adaptive Cognitive Emotion Regulation Strategies

다국어 초록 (Multilingual Abstract)

The purpose of this study was to verify the mediating effect of experiential avoidance in the relationship between existential vacuum and smartphone overdependence, as well as the moderating effect of adaptive cognitive emotion regulation strategies(A-CER) in the relationship between existential vacuum and experiential avoidance. To this end, an online survey was conducted with university students attending universities located in the Daegu-Gyeonbuk region, and data from a total of 221 participants were used for analysis.
First, existential vacuum had a significant positive effect on smartphone overdependence, indication that higher levels of existential vacuum were associated with stronger tendencies toward smartphone overdependence.
Second, experiential avoidance showed a significant mediation effect in the relationship between existential vacuum and smartphone overdependence. This result suggests that existential vacuum resulting from a loss of meaning in life increases avoidance of psychological discomfort, which in turn contributes to excessive dependence on smartphone.
Third, adaptive cognitive emotion regulation stratagies were found to moderate the effect of existential vacuum on experiential avoidance. Specifically, the moderating effect of A-CER differed according to the level of existential vacuum, such that the protective effect was evident when existential vacuum was low but weakened when existential vacuum was high.
Fourth, the mediating effect of experiential avoidance was partially moderated by adpative cognitive emotion regulation strategies; however, the moderated mediating effect did not emerge in the expected buffering direction. In other words, higher levels of A-CER did not consistently reduce the indirect effect of existential vacuum on smartphone overdependence through experiential avoidance.
These results show that existential vacuum could influence smartphone overdependence by strengthening experiential avoidance coping and suggest that the protective function of cognitive emotion regulation strategies may be limited depending on the level of existential vacuum. This study underscores the importance of existential and process-based factors in understanding smartphone overdependence and highlights the need for differentiated intervention approaches based on levels of existential vacuum.
