The Centrality of Doubting and Checking in the Network Structure of Obsessive-Compulsive Symptom Dimensions in Youth.

Objective: Obsessive-compulsive disorder (OCD) is a heterogeneous condition with well-established symptom dimensions across the lifespan. The objective of the present study was to use network analysis to investigate the internal structure of these dimensions in unselected schoolchildren and in children with OCD.

Method: We estimated the network structure of OCD symptom dimensions in 6,991 schoolchildren and 704 children diagnosed with OCD from 18 sites across 6 countries.

[Sluggish cognitive tempo: an updated review].

Introduction: The study of sluggish cognitive tempo (SCT) arose largely from research carried out on attention deficit hyperactivity disorder (ADHD). This construct is defined by a range of behavioural symptoms such as the appearance of drowsiness, daydreaming, physical hypoactivity, little initiative, lethargy and apathy.

Development: The construct of SCT is reviewed by means of recently published papers on its clinical characteristics, associated symptoms, evaluation, prevalence, aetiology, comorbidity, neuropsychological profiles and treatment.
