Few studies to date have addressed whether the importance of family sport culture is stable or changes during the teenage years. This article examines the association between family sport culture and participation in…

This longitudinal, population-based study investigated associations between language problems (LP) and emotional and behavioural difficulties (EBD). Parents and teachers gave information about LP and EBD when the children were 7-9 (T1) and 11-13 years old (T2). Self-reports of EBD were included at T2. In line with findings from clinically referred…

Baron-Cohen ("Trends Cogn Sci" 6(6):248-254, 2002) suggested ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N = 53,728 18-month-old toddlers, including n…

Because children with externalizing behavior also tend to display low levels of social skills, we do not know if one or both of these…

Research on older children and studies contrasting preschoolers with high versus low behavioral inhibition (BI) highlight several risk factors, but these have not been investigated in community samples of young children. Child, parent, and peer factors at age 4 were therefore…

The study examines how parents experience the interaction with teachers and school; do they feel welcome, do they feel that they can influence what goes on in school?
