Pragmatic Competency and Obsessive-Compulsive Disorder: A Comparative Assessment with Normal Controls.

Area of Science:

• Psycholinguistics
• Clinical Psychology
• Neuroscience

Background:

• Cognitive impairments like autism and schizophrenia have well-documented speech pattern alterations.
• The pragmatic competence in individuals with obsessive-compulsive disorder (OCD) remains underrepresented in scientific literature.
• Understanding pragmatic abilities in OCD is crucial for differential diagnosis and targeted interventions.

Purpose of the Study:

• To investigate and compare the pragmatic recognition and production abilities of individuals with OCD versus neurotypical controls.
• To assess specific speech acts, namely requests and apologies, in high power distance situations.
• To evaluate non-verbal communication and expressive skills using the Orion's Pragmatic Language Skills (OPLS) checklist.

Main Methods:

• A discourse completion test was administered to assess pragmatic recognition of requests and apologies.
• An interview-based assessment using the OPLS subscales evaluated pragmatic production and communication behaviors.
• Participants included individuals diagnosed with OCD and a matched neurotypical control group.

Main Results:

• No statistically significant differences were found between OCD and control groups in pragmatic recognition.
• While neurotypical controls showed superior non-verbal communication and expressive skills, overall pragmatic production ability was comparable between groups.
• The findings suggest that core pragmatic production skills are largely intact in individuals with OCD.

Conclusions:

• Obsessive-compulsive disorder (OCD) does not appear to significantly impair overall pragmatic recognition or production abilities.
• Specific deficits in non-verbal communication and expressive skills may be present in OCD, warranting further investigation.
• Results contribute to differentiating OCD's pragmatic profile from those observed in autism and social anxiety disorders.
