A twin study of genetic and environmental contributions to ADHD (Attention-Deficit/Hyperactivity Disorder) over time
Open Access paper from the JCPP – ‘We investigated whether the genetic and environmental variance underlying ADHD, and traits of ADHD, has changed over time’. Mark J. Taylor (pic) et al.

A cross-lagged twin study of emotional symptoms, social isolation and peer victimisation from early adolescence to emerging adulthood
Open Access paper from JCPP Advances – ‘Our study highlights the necessity to intervene early in adolescence to prevent the escalation of emotional symptoms over time and to consider social isolation and peer victimisation as important risk factors for the long-term persistence of emotional symptoms.’ Geneviève Morneau-Vaillancourt (pic) et al.

Sub-types of insomnia in adolescents: Insights from a quantitative/molecular twin study
Open Access paper from JCPP Advances – ‘Insomnia with short sleep duration has been postulated as more severe than that accompanied by normal/long sleep length. While the short duration subtype is considered to have greater genetic influence than the other subtype, no studies have addressed this question’. Juan J. Madrid-Valero (pic) et al.

Self-control and grit are associated with school performance mainly because of shared genetic effects
Open Access paper from JCPP Advances – ‘By combining the classical twin design with regression analysis, we investigated the role of two non-cognitive factors, self-control and grit, in the prediction of school performance. We did so at the phenotypic, genetic, and environmental level’. Sofieke T. Kevenaar et al.

Methodological Review: Twins Early Development Study (TEDS): A genetically sensitive investigation of mental health outcomes in the mid-twenties
Open Access paper from JCPP Advances – ‘This paper outlines recent data collection efforts supporting this work, including a cohort-wide mental health assessment at age 26 and a multi-phase Covid-19 study.’ Celestine Lockhart et al.

Pre-pragmatic language use in toddlerhood: Developmental antecedents, aetiological factors, and associations to autism
Open Access paper from JCPP Advances – “Little is known about the factors that contribute to decontextualized language use in toddlers and whether these are different from factors contributing to general language development. We studied longitudinal associations between parent-rated core language and non-verbal socio-communicative abilities at 14 months of age, and decontextualized language use at 24 months of age in children with typical and elevated likelihood of ASD (total N = 303).” Maja Rudling (pic) et al.

Explaining the influence of non-shared environment (NSE) on symptoms of behaviour problems from preschool to adulthood: mind the missing NSE gap
Open Access paper from the JCPP – “We assessed the extent to which variance in behaviour problem symptoms during the first two decades of life can be accounted for by measured NSE effects after controlling for genetics and shared environment”. Agnieszka Gidziela et al.

Preferential looking to eyes versus mouth in early infancy: heritability and link to concurrent and later development
In a sample of 535 5-month-old infant twins, we assessed eye (relative to mouth) preference in early infancy we investigated the contribution of genetic and environmental factors to the preference for looking at eyes, and the association with concurrent traits and follow-up measures. Charlotte Viktorsson (pic) et al
