BACKGROUND Negative parenting practices may be an environmental risk factor for subsequent conduct problems. Research on the association between parenting practices and callous-unemotional traits, a risk factor for conduct problems, has produced mixed findings. AIMS To investigate whether negative parental discipline is a non-shared environmental risk factor for the development of conduct pro...

Anxiety and conduct problems covary, yet studies have not explored the genetic and environmental origins of this association. We analyzed parent-reported anxiety and conduct problems in 6,783 pairs of twins at 2-, 3-, and 4-years of age. As anxiety and conduct problems were fairly stable across the three ages (average 1-year correlation was .53), ratings from all three were combined. The aggreg...

Conduct problems in childhood often co-occur with symptoms of depression. This study explored whether the development of conduct problems becomes indirectly linked to depressive symptoms in a sample of 323 kindergarten children, followed over a period of 2 school years. Results showed that the development of conduct problems was indirectly linked to the development of depressive symptoms via ex...

A sample of 6- to 13-year-old clinic-referred (n = 136) and volunteer (n = 30) participants was investigated for a potential interaction between the quality of parenting that a child receives and callous-unemotional traits in the child for predicting conduct problems. Ineffective parenting was associated with conduct problems only in children without significant levels of callous (e.g. lack of ...

This study investigated the mechanisms by which experiences of poverty influence the trajectory of conduct problems among preschool children. Drawing on two theoretical perspectives, we focused on family stress (stress and harsh discipline) and investment variables (educational investment, nutrition, and cognitive ability) as key mediators. Structural equation modeling techniques with prospecti...

BACKGROUND Although childhood hyperactivity and conduct problems are associated with difficulties in adulthood, little is known about later service use or public expenditure costs in the UK. AIMS To describe the use of services and calculate recent (past 6 months) and early adulthood (since the age of 18 years) public expenditure costs incurred by young adults who had hyperactivity and/or con...

Individual heterogeneity exists in the onset and development of conduct problems, but theoretical claims about predictors and prognosis are often not consistent with the empirical findings. This study examined shape and outcomes of conduct problem trajectories in a Belgian population-based sample (N = 682; 49.5 % boys). Mothers reported on children's conduct problems across six waves (age 4-17)...

The development of conduct problems in childhood and adolescence is associated with adverse long-term outcomes, including psychiatric morbidity. Although genes constitute a proven factor of stability in conduct problems, less is known regarding their role in conduct problems' developmental course (i.e. systematic age changes, for instance linear increases or decreases).Mothers rated conduct pro...
