Links Among Childhood Trauma, Uncertainty Intolerance, and Severity of Symptoms in OCD
Overview
This study investigates the relationship between childhood trauma (CT), intolerance of uncertainty (IU), and obsessive-compulsive symptom (OCS) severity in patients with OCD. Findings indicate that patients with OCD exhibit higher levels of CT and IU compared to healthy controls.
Background
Childhood trauma is frequently linked to various psychiatric disorders, including obsessive-compulsive disorder (OCD). Intolerance of uncertainty may play a role in this relationship.

Key Findings
Patients with OCD scored significantly higher on all CTQ-33 subscales compared to healthy controls.
Intolerance of uncertainty (IUS-12) total scores were higher in OCD patients (39.30) than in healthy controls (32.11).
Prospective anxiety and inhibitory anxiety scores were also significantly elevated in OCD patients.
Physical abuse was the only CT dimension significantly associated with total Y-BOCS scores in the OCD group.
Path analysis indicated that IU partially mediates the relationship between CT and OCS severity.
Clinical Implications
Assessing intolerance of uncertainty may provide insights for clinicians treating patients with OCD, particularly those with a history of childhood trauma.
Conclusion
The study highlights the elevated levels of childhood trauma and intolerance of uncertainty in OCD patients.
