OBJECTIVE: Little is known about the role of childhood experiences in the development of obsessive-compulsive disorder (OCD). However, the influence of childhood experiences on personality, behavior, and perceived stress may vary between OCD patients and healthy individuals. The objective of this study was to use network analysis to explore the relationship between childhood trauma, personality, perceived stress, and symptom dimensions, thus finding the difference between patients' and healthy people's network.
METHODS: 488 patients with OCD and 210 healthy volunteers were recruited. All of them were assessed with the Obsessive-Compulsive Inventory - Revised (OCI-R), the Perceived Stress Scale-10, the NEO Five-Factor Inventory and the Early Trauma Inventory Self-Report Short Form. Network analysis was conducted and the centrality indices were calculated. Network comparison test was performed.
RESULTS: In patients' network, the Obsession and the Ordering behavior were the most important nodes among the OCI-R. The perceived stress showed the strongest strength centrality of all nodes and positive correlation with the Obsession and Neuroticism. Network comparison test results indicated a statistically significant difference between network structure, and post-hoc analysis found five edges significantly differed between patients and healthy controls, mainly on Obsession and Washing behaviors.
CONCLUSIONS: Emotional abuse was considered significant in both networks due to its higher strength centrality. Meanwhile, perceived stress was found to be more significant in the patient network and exhibited stronger associations with obsession. The obsessive thoughts and washing behavior were different among patients and healthy controls, which brought new understanding to the pathopsychological mechanisms of OCD.
