Initiation and stability of self-harm in adolescence and early adulthood: investigating social and aetiological factors in twins.

Background: Almost one in five (18.8%) UK adolescents are estimated to self-harm and many young people initiate self-harm early (average age 13 years). Prevention of self-harm should be informed by knowledge about risk factors (e.

Exploring associations between ADHD symptoms and emotional problems from childhood to adulthood: shared aetiology or possible causal relationship?

Background: ADHD symptoms are associated with emotional problems such as depressive and anxiety symptoms from early childhood to adulthood, with the association increasing with age. A shared aetiology and/or a causal relationship could explain their correlation. In the current study, we explore these explanations for the association between ADHD symptoms and emotional problems from childhood to adulthood.

Intergenerational consequences of racism in the United Kingdom: a qualitative investigation into parents' exposure to racism and offspring mental health and well-being.

Background: Experiences of racism are linked to negative physical and mental health outcomes among those exposed. According to quantitative research derived mainly from the United States, these negative outcomes can have cascading effects in families, when parents' experiences of racism indirectly impact offspring. New research is warranted for families in the United Kingdom, informed by a qualitative approach to canvassing community knowledge and perspectives, exploring how existing findings relate to lived experiences.

Comparing findings from the random-intercept cross-lagged panel model and the monozygotic twin difference cross-lagged panel model: Maladaptive parenting and offspring emotional and behavioural problems.

Background: In this study we compare results obtained when applying the monozygotic twin difference cross-lagged panel model (MZD-CLPM) and a random intercept cross-lagged panel model (RI-CLPM) to the same data. Each of these models is designed to strengthen researchers' ability to draw causal inference from cross-lagged associations. We explore differences and similarities in how each model does this, and in the results each model produces.
