Abstract
Obsessive-compulsive disorder (OCD) and trichotillomania (hair pulling disorder, HPD) are both considered obsessive-compulsive and related disorders due to some indications of shared etiological and phenomenological characteristics. However, a lack of direct comparisons between these disorders, especially in pediatric samples, limits our understanding of divergent versus convergent characteristics. This study compared neurocognitive functioning between children diagnosed with OCD and HPD. In total, 21 children diagnosed with HPD, 40 diagnosed with OCD, and 29 healthy controls (HCs), along with their parents, completed self-/parent-report measures and a neurocognitive assessment battery, which included tasks of inhibitory control, sustained attention, planning, working memory, visual memory, and cognitive flexibility. A series of analyses of variance (or covariance) indicated significant differences between groups on tasks examining planning and sustained attention. Specifically, children in both the OCD and HPD groups outperformed HCs on a task of planning. Further, children with OCD underperformed as compared to both the HPD and HC groups on a task of sustained attention. No between group differences were found with respect to tasks of reversal learning, working memory, spatial working memory, visual memory, or inhibitory control. The implications these findings may have for future, transdiagnostic work, as well as limitations and future directions are discussed.
期刊介绍:
Research on Child and Adolescent Psychopathology brings together the latest innovative research that advances knowledge of psychopathology from infancy through adolescence. The journal publishes studies that have a strong theoretical framework and use a diversity of methods, with an emphasis on empirical studies of the major forms of psychopathology found in childhood disorders (e.g., disruptive behavior disorders, depression, anxiety, and autism spectrum disorder). Studies focus on the epidemiology, etiology, assessment, treatment, prognosis, and developmental course of these forms of psychopathology. Studies highlighting risk and protective factors; the ecology and correlates of children''s emotional, social, and behavior problems; and advances in prevention and treatment are featured.
Research on Child and Adolescent Psychopathology is the official journal of the International Society for Research in Child and Adolescent Psychopathology (ISRCAP), a multidisciplinary scientific society.
