The Mediating Role of Negative Spiritual Coping in the Relationship between Dark Triad Personality and Nonsuicidal Self- Injury in Adolescents

The aim of the present study was to investigate the mediating role of negative spiritual coping in the relationship between dark triad personality and nonsuicidal self-injury in adolescents. This study is fundamental in terms of purpose and descriptive correlation in terms of method. The statistical population of this study consisted of all high school students in public schools in Karaj in the academic year 2020-2021. The sample consisted of 351 high school students who were selected by stage cluster sampling and online during Covid 19 disease. Participants completed the dark personality scale (DPS) Jonason & Webster (2010), the spiritual coping questionnaire (SCQ) Charzyńska (2015), and the deliberate self–harm inventory (DSHI) Gratz (2001). The Pearson correlation and structural equation modeling methods were used for data analysis. The results showed that the model related to the mediating role of negative spiritual coping in the relationship between dark triad personality and nonsuicidal self-injury of adolescents has a good fit. The results showed that the direct effect of dark triad personality on non-suicidal self-injury is not significant (P>0.05). The direct effect of negative spiritual coping (P<0.01) and the indirect effect of dark triad personality with the mediation of negative spiritual coping on non-suicidal self-injury are significant (P<0.01); Therefore, paying attention to these variables in the field of psychopathology and formulating educational and therapeutic interventions regarding nonsuicidal self-injury can be useful.
