Obsessive-Compulsive Disorder with Psychotic Features: Is It a Clinical Entity?

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• The increasing recognition of comorbidity between obsessive-compulsive disorder (OCD) and psychotic disorders (PD) necessitates understanding its clinical implications.
• Previous research has not fully elucidated how the presence of PD affects the presentation and functional outcomes in individuals with OCD.

Purpose of the Study:

• To investigate the clinical differences between OCD patients with and without comorbid PD.
• To assess the impact of comorbid PD on insight into obsessive-compulsive symptoms and overall functioning in OCD patients.

Main Methods:

• A cross-sectional study involving 86 Japanese outpatients diagnosed with OCD according to DSM-IV-TR criteria.
• Participants were divided into two groups: 28 with comorbid PD and 58 without PD.
• Sociodemographic profiles and clinical characteristics, including the DSM-IV-TR insight specifier and Global Assessment of Functioning (GAF) scores, were compared between groups.

Main Results:

• OCD patients with comorbid PD demonstrated significantly lower scores on insight assessments compared to those without PD.
• The Global Assessment of Functioning (GAF) scores were also lower in the group of OCD patients with comorbid PD, indicating impaired overall functioning.

Conclusions:

• The findings suggest that the presence of comorbid psychotic disorders in individuals with OCD represents a distinct clinical entity.
• Comorbid PD in OCD is associated with diminished insight into symptoms and reduced functional capacity, warranting specific clinical attention and management strategies.
