Sensory Processing and Performance-Based Executive Functioning in Adolescent Obsessive Compulsive Disorder: An...

Area of Science:

• Neuroscience
• Psychiatry
• Developmental Psychology

Background:

• Pediatric obsessive-compulsive disorder (OCD) research often studies sensory processing and executive functions (EF) separately.
• Understanding the interplay between OCD severity, sensory processing, and EF is crucial for adolescents with OCD.

Purpose of the Study:

• To examine the relationships among OCD symptom severity, sensory processing, and performance-based EF in adolescents with OCD.
• To assess if sensory processing and OCD symptom severity predict executive outcomes.

Main Methods:

• One hundred adolescents (12-18 years) with DSM-5 diagnosed OCD were assessed.
• Measures included the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) for symptom severity, Adolescent/Adult Sensory Profile (AASP) for sensory processing, and multiple tests for EF (WCST, SCWT, CCTT, VFT).
• Bivariate correlations and multivariate linear regression were used for analysis.

Main Results:

• OCD symptom severity (CY-BOCS) correlated with sensory sensitivity, sensory avoiding, and low registration.
• Greater OCD severity was linked to poorer performance on the Wisconsin Card Sorting Test (WCST) and longer completion time on the Children's Color Trails Test (CCTT-2).
• Regression models showed OCD severity independently predicted poorer WCST performance and longer CCTT-2 times, but sensory processing measures did not independently predict EF outcomes.

Conclusions:

• Sensory processing characteristics are associated with OCD symptom severity in adolescents.
• OCD symptom severity is independently linked to cognitive flexibility-related executive function deficits in this population.
• Further research with longitudinal and comparative designs is needed to clarify the directionality and clinical significance of these findings.
