Children with Obsessive-Compulsive Symptomology in the General Population: Different Subtypes?

Area of Science:

• Child and Adolescent Psychiatry
• Neurodevelopmental Disorders
• Pediatric Psychology

Background:

• Obsessive-compulsive disorder (OCD) is a neurodevelopmental disorder with high comorbidity.
• Early-stage psychiatric symptoms are often difficult to attribute to specific disorders.
• Subclinical obsessive-compulsive (OC) symptoms are common in school-aged children.

Purpose of the Study:

• To investigate if distinct neuropsychiatric symptom profiles exist in children with high OC symptoms.
• To analyze symptom heterogeneity within a large population-based sample of school-aged children.
• To identify potential developmental trajectories based on symptom clusters.

Main Methods:

• Latent profile analysis was conducted on a high-OC sample (n=209) from a larger population study (n=4632).
• Assessed symptoms included those related to attention-deficit hyperactivity disorder, oppositional defiant disorder, autism, and anxiety.
• Z-scores of comorbid symptom measures were used as indicators for profile analysis.

Main Results:

• Three distinct profiles emerged within the high-OC sample.
• Profile 1 (OC-specific, 81.3%) showed only OC-specific problems.
• Profile 2 (Comorbid OC, 11.0%) exhibited high scores across all comorbid symptom measures.
• Profile 3 (Autistic OC, 7.7%) was characterized by particularly high scores on autism-related symptoms.

Conclusions:

• Distinct neuropsychiatric symptom profiles can be identified in school-aged children with high OC symptoms.
• These identified profiles may inform the understanding of symptom course during development.
• Longitudinal studies are needed to confirm if these subgroups maintain distinct profiles and trajectories over time.
