정서 반응성이 비자살적 자해에 미치는 영향 : 부정 긴급성의 매개 효과

Abstract

This study examined whether negative urgency, a negative emotion-based impulsivity, would mediate the relationship between emotion reactivity and non-suicidal self-injury (NSSI) in college students. To examine this hypothesis, participants (N=1,221) completed the Emotion Reactivity Scale (ERS), UPPS-P Impulsive Behavior Scale - Negative Urgency, Functional Assessment of Self-Mutilation (FASM) through an online survey on social networking services (SNS), and only data from those who experienced more than one NSSI (N=357) were used for statistical analysis. For correlation analysis and testing Structural Equational Model(SEM), the data collected in the study were analyzed using SPSS 25.0 and AMOS 26.0. The results of the study can be summarized as follows. First, in the relationship between emotion reactivity, negative urgency, and non-suicidal self-injury, emotional reactivity was positively correlated with negative urgency and NSSI. Also, negative urgency indicated a significant positive correlation to NSSI. Second, negative urgency mediated the relationship between emotion reactivity and NSSI. In other words, emotional reactivity had not only a direct effect on NSSI but also an indirect effect, by mediating the negative urgency. The results of this study can help to gain a broader understanding of the mechanisms of NSSI. In addition, these findings have clinical implications for therapeutic prevention and intervention of NSSI, and suggest that negative urgency (i.e. NSSI-specific vulnerability factor that includes emotional and behavioral aspects), as well as emotion reactivity (i.e. an emotionally predisposing factor) should be considered as an important risk factor in the engagement of NSSI. Limitations of the current study and recommendations for future research were discussed.
