Summary

Subclinical obsessive-compulsive traits are linked to poorer design fluency, a cognitive skill. This suggests right corticostriatal system involvement even in milder forms of obsessive-compulsive behaviors.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Psychiatry

Background:

  • Obsessive-compulsive disorder (OCD) is associated with cognitive deficits.
  • The role of corticostriatal systems in OCD is increasingly recognized.
  • Subclinical symptoms may reflect early-stage or milder forms of the disorder.

Purpose of the Study:

  • To investigate verbal and design fluency in individuals with subclinical obsessive-compulsive traits.
  • To explore the relationship between obsessionality and fluency abilities.
  • To provide further evidence for the neural underpinnings of obsessive-compulsive behaviors.

Main Methods:

  • Comparative analysis of verbal and design fluency.
  • Assessment of 25 subclinical obsessive-compulsive subjects and 27 noncompulsive controls.

  • Correlation analysis between obsessionality scores and fluency performance.

    • Main Results:

    • The subclinical obsessive-compulsive group demonstrated significantly reduced design fluency compared to controls.
    • Design fluency performance was negatively correlated with the degree of obsessionality.
    • Verbal fluency did not show significant differences between groups.

    Conclusions:

    • Reduced design fluency is a potential cognitive marker for subclinical obsessive-compulsive traits.
    • These findings support the involvement of right corticostriatal systems in the cognitive profile of obsessive-compulsive tendencies.
    • The results extend previous findings on corticostriatal dysfunction in OCD to individuals with subclinical symptoms.
