Introduction: With the growing number of opioid users, as well as with the non-compliance with methadone maintenance protocol principles in terms of dosage and occasional impulsive increases in dosage due to lack of effective emotional regulation, The present study was conducted with the aim of investigating the structural relationships of childhood trauma experience with emotional dysregulation in methadone treated individuals with the mediating role of mentalization.
Methods: The statistical population in this study included all drug-dependent patients treated with methadone who referred to addiction treatment centers in Qazvin city in 2023, of which 220 people were selected using the available sampling method. In order to collect data, Childhood Trauma Questionnaire, reflective functioning questionnaire, and difficulties in emotion regulation scale were used. For data analysis, Pearson correlation, structural equation modeling and SPSS-18 and AMOS-24 software were used.
Results: The findings indicate the fit of the assumed model. The present research is a descriptive-correlation type of structural equations. The direct effect of childhood trauma (T=2.11, β=0.43) and mentalization (uncertainty component) (T=5.65, β=0.41) on meaningful and positive on emotional dysregulation and the direct effect of mentalization (uncertainty component) (T = -3.32, β = -0.47) on emotional dysregulation was significant and negative. Also, the analysis of research findings indicated the mediating role of mentalization in the relationship between childhood trauma experience and emotional dysregulation. The results also showed that the research variables explained a total of 56% of the variance of emotional dysregulation. The results also showed that the research variables explained a total of 56% of the variance of emotional dysregulation.
Conclusions: Early traumatic experiences, especially with caregivers, create an environment that invalidates the child's emotions and feelings, and in this unsafe environment, the child uses incompatible strategies such as suppressing or avoiding negative emotions. It may lead to substance abuse problems in adulthood, On the other hand, in spite of traumatic experiences, if people acquire a high psychological capacity and understanding and insight into their mental processes (mentalization capacity), they will not resort to drugs in order to regulate their impulses and emotions. Therefore, it is suggested to pay special attention to the treatments based on mentalization and the treatments based on emotion regulation in people treated with methadone.
