Comparing impulsivity in borderline personality, schizophrenia and obsessional-compulsive disorders: Who is ahead?

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Impulsivity is a key feature in psychiatric disorders, impacting severity and prognosis.
• Borderline personality disorder (BPD), Schizophrenic disorder (SZD), and Obsessive-Compulsive Disorder (OCD) are associated with significant impulsivity issues.
• Understanding comparative impulsivity profiles is crucial for diagnosis and treatment.

Purpose of the Study:

• To compare impulsivity and urgency levels across BPD, SZD, and OCD patient groups.
• To assess differences in specific facets of impulsivity, including urgency, premeditation, and sensation seeking.
• To examine the relationship between impulsivity measures and disorder-specific symptom scales.

Main Methods:

• Recruited 90 patients diagnosed with OCD (n=25), SZD (n=23), and BPD (n=50), alongside 24 healthy controls (HC).
• Administered validated assessments to measure impulsivity and urgency.
• Analyzed group differences in impulsivity scores and correlations with clinical measures.

Main Results:

• BPD patients exhibited significantly higher overall impulsivity and urgency compared to HC, SZD, and OCD groups.
• HC, SZD, and OCD groups did not differ in global Urgency-Premeditation-Perseverance-Sensation seeking scores.
• OCD patients showed higher urgency than HC, while SZD and HC groups were equivalent. Urgency correlated with SZD severity, but no link was found between BPD and OCD symptom scales.

Conclusions:

• Findings suggest BPD is characterized by higher impulsivity and urgency than SZD and OCD.
• The results challenge existing literature regarding the role and level of impulsivity in SZD.
• Further research is needed to clarify the complex relationship between impulsivity and SZD.
