Does cognitive-behavioral therapy response among adults with obsessive-compulsive disorder differ as a function of...

Area of Science:

• Psychiatry and Behavioral Science
• Clinical Psychology

Background:

• Obsessive-compulsive disorder (OCD) frequently co-occurs with other psychiatric conditions.
• The impact of these common comorbidities on treatment response in OCD is not fully understood.
• Understanding comorbidity effects is crucial for tailoring effective interventions for OCD.

Purpose of the Study:

• To investigate the influence of common comorbid psychiatric disorders on cognitive-behavioral therapy (CBT) response in adults with OCD.
• To assess whether generalized anxiety disorder (GAD), major depressive disorder (MDD), social phobia, or panic disorder affect OCD treatment outcomes.

Main Methods:

• One hundred forty-three adults diagnosed with OCD participated in the study.
• Participants received 14 sessions of either weekly or intensive CBT.
• Assessments of OCD severity (Yale-Brown Obsessive-Compulsive Scale - Y-BOCS), response rates, and remission status were conducted pre- and post-treatment.

Main Results:

• Sixty-nine percent of participants presented with at least one comorbid psychiatric diagnosis.
• Neither the presence nor the number of pre-treatment comorbidities predicted symptom severity, treatment response, remission, or clinically significant changes.
• Slightly higher baseline OCD severity was noted in individuals with OCD+MDD and OCD+GAD compared to OCD-only.

Conclusions:

• Cognitive-behavioral therapy (CBT) for obsessive-compulsive disorder (OCD) demonstrates robustness in the presence of common Axis-I comorbidities.
• Common comorbid disorders such as MDD and GAD do not appear to significantly impede CBT effectiveness for OCD.
• These findings support the general applicability of CBT for OCD patients, irrespective of common co-occurring conditions.
