Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Sleep disturbance as a transdiagnostic marker of children's mental health difficulties: A network analysis of item‐level associations between different types of sleep problems and different behavioural and emotional symptoms

Abstract Background Sleep disturbances are widely considered to be a transdiagnostic feature of common behavioural and emotional difficulties in childhood, yet most studies treat sleep as a single construct. Where studies have explored specific sleep problems to psychopathology in children, these tend to only include behavioural or emotional ...

Investigating the toll of childhood socioeconomic disadvantage on adolescent mental health in three UK cohorts

open access: yesJCPP Advances, EarlyView.
Abstract Background Low socioeconomic position (SEP) in childhood is robustly associated with adolescent mental health difficulties, yet this relationship is changing over time due to contextual and conceptual differences in these constructs. Consistent SEP and mental health data from different cohorts are required to understand changes over time ...

Implications of attention‐deficit/hyperactivity disorder diagnostic timing on mental health service utilisation in young adult females: A population‐based record linkage cohort study

open access: yesJCPP Advances, EarlyView.
Abstract Background Sex differences in the frequency and timing of attention‐deficit/hyperactivity disorder (ADHD) diagnosis exist. While there are multiple known individual and wider consequences for young females with delayed or undiagnosed ADHD, little is known about mental health service utilisation (HSU) impacts.

Differences in associations between attention‐deficit hyperactivity disorder symptoms and physical activity across childhood and adolescence and among males and females in a representative UK birth cohort

open access: yesJCPP Advances, EarlyView.
Abstract Background Children and adolescents with attention‐deficit hyperactivity disorder (ADHD) exhibit higher physical activity (PA) levels than peers without ADHD. It remains unclear how this association evolves across developmental stages and differs between sexes.
