Abstract
Introduction: A wide range of genetic, neurological, psychological, and social factors are involved in the etiology of obsessive-compulsive disorder, and its onset can occur through various pathways. This study aimed to determine the mediating role of thought-action fusion and experiential avoidance in the relationship between childhood trauma and obsessive-compulsive symptoms in adults.
Methods: The descriptive-correlation research method was structural equations. The statistical population of this study consisted of all individuals referring to clinics and psychological service centers in Tehran in 2024. Of these individuals, 260 were selected using convenience sampling. The tools used in this study include: Childhood Trauma Questionnaire, Fusion of Thought- Action scale, Acceptance and Action Questionnaire (AAQ-II), and the Obsessive–compulsive Disorder- revision (OCDR). Data analysis was also performed using Pearson correlation, structural equation modeling, and SPSS-26 and AMOS-24 software.
Results: The results showed that the research model had a good fit and the direct effect of childhood trauma (P=<0.001; t=5.64, β=0.33), thought-action fusion (P=0.001; t=11.27; β=0.82), and experiential avoidance (P=0.001; t=10.68; β=0.66) on obsessive-compulsive symptoms was significant and positive. Also, the variable indirect effect of childhood trauma on obsessive-compulsive symptoms through the mediating role of thought-action fusion was meaningful (b=0.66, P<0.05), and the indirect effect of childhood trauma on obsessive-compulsive symptoms through the role the mediator of experiential avoidance was significant (P<0.05, b=0.53). In addition, the results also showed that the research variables explain a total of 68% of the variance of obsessive-compulsive symptoms.
Conclusions: The results indicated the mediating role of thought-action fusion and experiential avoidance between childhood trauma and obsessive-compulsive symptoms. These findings show that reducing experiential avoidance and thought-action fusion may be a suitable way to complete the treatment of obsessive-compulsive symptoms in people suffering from childhood trauma.
