Exploring the Interplay between Complex Post-Traumatic Stress Disorder and Obsessive-Compulsive Disorder Severity:...

Area of Science:

• Psychiatry
• Clinical Psychology
• Trauma Studies

Background:

• Traumatic events negatively influence the clinical progression of obsessive-compulsive disorder (OCD).
• Understanding the link between prolonged interpersonal trauma and OCD/anxiety symptom severity is crucial for effective treatment.

Purpose of the Study:

• To investigate the correlation between prolonged interpersonal trauma and the severity of OCD and anxiety symptoms.
• To explore the impact of complex post-traumatic stress disorder (cPTSD) on individuals with OCD.

Main Methods:

• Cross-sectional, observational study design.
• Utilized the International Trauma Questionnaire (ITQ), Hamilton Anxiety Rating Scale (HAM-A), and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).
• Employed descriptive analysis, ANOVA, and logistic regression.

Main Results:

• 107 OCD patients were analyzed, with subgroups based on cPTSD presence.
• Significant differences observed in OCD onset age, familial psychiatric history, HAM-A, and Y-BOCS scores between cPTSD+ and cPTSD- groups.
• cPTSD presence strongly associated with increased Y-BOCS scores (p < 0.0001).

Conclusions:

• Co-occurring cPTSD in OCD patients exacerbates obsessive-compulsive symptoms and heightens anxiety.
• Early trauma significantly impacts the trajectory of OCD and associated anxiety.
• Further research is needed to develop interventions mitigating early trauma's effects on OCD.
