DNA methylation at birth and lateral ventricular volume in childhood: a neuroimaging epigenetics study
Open Access paper from the JCPP – ‘In this study, we conducted the first epigenome-wide association study of neonatal DNAm in cord blood with LVV in childhood (measured using T1-weighted brain scans at 10 years), based on data from a large population-based birth cohort, the Generation R Study (N = 840)’.

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.

Negative parenting, epigenetic age, and psychological problems: prospective associations from adolescence to young adulthood
Open Access paper from the JCPP – ‘This pre-registered longitudinal study examined the long-term effects of negative parenting and psychological problems throughout adolescence (ages 13–17 years) on Epigenetic Age acceleration (EA) in late adolescence (age 17 years) and EA changes from late adolescence to young adulthood (age 25 years).’ Stefanos Mastrotheodoros 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.

Family environment and polygenic risk in the bipolar high-risk context
Open Access paper from JCPP Advances – ‘We tested the association of offspring-perceived family environment in interaction with bipolar disorder-polygenic risk on liability for bipolar disorder in offspring at high or low familial risk for bipolar disorder. We used a novel stepwise approach for latent class modeling with predictors and distal outcomes.’ Emma K. Stapp (pic) et al.
