ABSTRACT
Objective:
To explore the effect of childhood trauma on non-suicidal self-injury and the chain mediating effect of rejection sensitivity and experiential avoidance.Methods:
From June 2021 to April 2022, totally 1 130 college students were investigated with childhood trauma questionnaire-short form(CTQ-SF), the tendency to expect rejection scale, acceptance and action questionnaire-2nd edition(AAQ-Ⅱ) and Ottwa self-injury inventory(OSI). SPSS 25.0 and Mplus 8.0 software were used for descriptive analysis, Spearman correlation analysis, structural equation model construction and Bootstrap mediation effect test.Results:
Correlation analysis showed that childhood trauma (34.64±8.25), rejection sensitivity (58.02±9.54), experiential avoidance (23.90±7.96) and non-suicidal self-injury (0(0, 1)) were all significantly positively correlated with each other( r=0.163-0.532, all P<0.01). Structural equation model showed that empirical avoidance played a partial mediating effect between childhood trauma and non-suicidal self-injury in college students, with an effect size of 0.045(95% CI=0.013-0.084). Rejection sensitivity and experiential avoidance played a chain mediating effect between childhood trauma and non-suicidal self-injury in college students, with an effect size of 0.017(95% CI=0.005-0.035).Conclusion:
Childhood trauma can directly predict non-suicidal self-injury in college students, and it can also indirectly predict non-suicidal self-injury through the partial mediation effect of experiential avoidance and the chain mediation effect of rejection sensitivity and experiential avoidance.
