Obsessive-compulsive disorder in children and youth: neurocognitive function in clinic and community samples / Russell SCHACHAR in Journal of Child Psychology and Psychiatry, 63-8 (August 2022)
[article]
Titre : Obsessive-compulsive disorder in children and youth: neurocognitive function in clinic and community samples Type de document : Texte imprimé et/ou numérique Auteurs : Russell SCHACHAR, Auteur ; Annie DUPUIS, Auteur ; Evdokia ANAGNOSTOU, Auteur ; Stelios GEORGIADES, Auteur ; Noam SORENI, Auteur ; Paul D. ARNOLD, Auteur ; Christie L. BURTON, Auteur ; Jennifer CROSBIE, Auteur Article en page(s) : p.881-889 Langues : Anglais (eng) Mots-clés : Adolescent Attention Child Comorbidity Humans Obsessive-Compulsive Disorder/diagnosis Phenotype Reaction Time/physiology Ocd Stop-signal task executive function neurocognition Index. décimale : PER Périodiques Résumé : BACKGROUND: Neurocognitive impairments are common in OCD, although not well studied in children and youth with the disorder. METHOD: Using the stop-signal task (SST), we measured response inhibition (stop-signal reaction time-SSRT), sustained attention (reaction time variability-RTV), reaction time (RT), and performance monitoring (post-error slowing-PES) in OCD cases and controls from two samples of children and youth. A Clinic OCD group (n=171, aged 7-17years) was recruited from a specialty clinic after rigorous assessment. A typically developing (Clinic TD, n=157) group was enlisted through advertisement. A community OCD sample (Community OCD, n=147) and controls (Community TD n=13,832, aged 6-17 years) were recruited at a science museum. We also identified a community group with high OCD traits without an OCD diagnosis (Community High Trait; n=125). RESULTS: Clinic OCD participants had longer SSRT and greater RTV than Clinic TD. These effects were greater in younger OCD participants and, for SSRT, in those on medication for OCD. The Community OCD group did not differ from Controls but was similar to the Clinic OCD group in ADHD and ASD comorbidity and medication usage. The Community High Trait group had longer SSRT and atypical PES suggesting that symptom severity predicts neurocognitive function. No group differences were found in RT. CONCLUSIONS: In the largest study of neurocognitive performance in children with OCD to date, we found impaired response inhibition and sustained attention in OCD participants in comparison to typically developing peers. Performance was worse in younger OCD participants. In the community sample, participants with high OCD trait scores but no OCD diagnosis had impaired response inhibition and error processing, suggesting that OCD might be under-recognized.

Perfectionism may be a viable candidate trait antecedent, given its role in the clinical manifestation of both OCPD and OCD in adulthood, and the evidence that perfectionism reflects a dispositional tendency observable from childhood onwards. However, little is known about childhood trajectories of perfectionism with prospective links to later OCPD versus OCD. Using latent growth curve modeling, this study explored the baseline and growth of childhood perfectionism in 485 community and referred children (55.5% girls, 7.17-14.78 years old, M(age) = 10.74, SD = 1.50) across three waves. Adolescent OCPD traits and OCD symptoms were measured in Wave 4. An overall decreasing trend of perfectionism from childhood through adolescence appeared, without inter-individual differences in growth. Individual differences in baseline levels of childhood perfectionism were significant, and equally predicting adolescent OCPD and OCD outcomes. At a more specific level, childhood perfectionism predicted most strongly the rigid perfectionism component of OCPD, and the orderliness/cleanliness/perfectionism and obsession domain of OCD. This demonstrates the value of childhood perfectionism for understanding differential outcomes of adolescent OCPD traits and OCD symptoms.
