Background & Aims: Since no study has been found regarding the structural relationship between the structural pattern of childhood trauma and the self-injurious behavior of adolescents with borderline personality traits based on the mediating role of cognitive regulation strategies, emotion, therefore, conducting this research lies in several fundamental aspects. First, considering the high prevalence of childhood trauma and its extensive and long-term effects on mental health, this research can contribute to a deeper understanding of the relationship between these traumatic experiences and self-injurious behaviors in adolescents with borderline personality traits. Identifying this relationship can help mental health professionals to identify risk factors better and apply preventive and therapeutic interventions in time. Second, by examining the mediating role of cognitive emotion regulation strategies, this research identifies the mechanisms through which childhood trauma leads to self-injurious behaviors. This knowledge can help develop and improve therapeutic interventions, especially through teaching teenagers more effective emotion regulation strategies, which can reduce self-injurious behaviors and improve their mental health. The results of this research can help increase the awareness of society and professionals about the importance of prevention and early treatment of childhood trauma and its effect on self-injurious behaviors during adolescence. This awareness can lead to improved mental health policies, improved education and treatment programs, and support for those at risk. Considering the lack of research findings in this field, the aim of this study was the structural pattern of childhood trauma with self-injurious behavior of teenagers with borderline personality traits based on the mediating role of cognitive emotion regulation strategies.
Methods: The descriptive research method was correlation type. The statistical population of this research consists of all students of the second secondary level of Tehran city in the academic year 2022-2023. In this study, 316 students out of 1153 students were selected using the multi-stage cluster sampling method. Data were collected using a non-suicidal self-injurious behavior questionnaire (Klonsky and Glenn, 2009), childhood trauma (Bernstein et al., 2003), and cognitive emotion regulation strategies (Garnefsky et al., 2001). The data were analyzed with Pearson correlation statistical methods, and structural modeling using SPSS and AMOS statistical software.
Results: The results of structural equation modeling showed that 0.04% of the changes related to adaptive cognitive-emotional regulation are explained by childhood trauma. 0.01% of changes related to maladaptive emotional cognitive regulation are explained by childhood trauma. Based on this, 72% of the changes related to adolescent self-injury are explained by childhood trauma and adaptive and maladaptive cognitive-emotional regulation. Self-injurious behaviors in adolescents are a function of childhood trauma and adaptive emotion cognitive regulation strategies mediate this relationship. The findings indicate the appropriate fit of the proposed model with the data.
Conclusion: In general, it can be said that the proposed structural model, which includes childhood trauma, self-injury in teenagers with borderline personality traits, and cognitive emotion regulation strategies, is a good fit. This means that this model has been able to explain the relationships between these factors well and match the data. Also, cognitive emotion regulation strategies play an important mediating role in this model. This means that the effect of childhood trauma on the self-injurious behaviors of teenagers with borderline personality traits is significantly transmitted through cognitive emotion regulation strategies. These findings emphasize the importance of psychological interventions in improving emotional regulation strategies as a key factor in reducing self-injurious behaviors and show that working with these strategies can reduce the negative effects of childhood trauma on self-injurious behaviors in adolescents. The present study has limitations that should be taken into consideration in future studies. First, the relative lack of diversity in some samples (for example, the student sample in the age range of 15 to 17 years) may moderate the generalizability of the results. Second, in this research, all data were collected using self-reporting methodology. It is therefore susceptible to the limitations of using a simple method of data collection. Therefore, it is better to use other measurement methods such as structured clinical interviews, behavioral rating scales, and direct evaluation of behavior in future research. Since the family factors and individual differences of teenagers are the background for formulating and implementing various interventions to correct and prevent mental injuries; It is suggested that future researchers should pay attention to other related variables such as individual differences in coping styles, personality traits, as well as family dimensions, such as the presence of family members with streaks of behavioral disorders and personality disorders, in order to complete the data of the current research. It is suggested to carry out screening tests every year at the school level, in order to identify cases that need intervention in the fields of health and mental health while examining the mental health status of adolescents, both boys and girls, and with the help of relevant organizations and the cooperation of families in In order to adjust the conditions of adolescents with mental disorders as well as their family problems, take practical steps to prevent their conditions from worsening and turning them into serious psychological injuries such as self-injurious behavior. It is also important to remember that the present study was a descriptive study. Therefore, drawing and matching communication patterns between variables in various samples according to the evolutionary level requires more studies to gain more validity for the findings of the current research.
