Factors Associated With Adult Mental Health and Children's Social Care Professionals' Family‐Focused Practice When Parents Have Mental Illness
While family focused practice can improve outcomes for families affected by parental mental illness, globally there is limited understanding regarding associated factors and enablers. This mixed methods study aimed to identify associated factors and enablers of family focused practice. A range of adult mental health and children's social care professionals in Northern Ireland completed the Family Focused Mental Health Practice Questionnaire (n = …
Attention control in preterm and term 5‐month‐old infants
Cross‐task stability refers to performance consistency across different settings and measures of the same construct. Cross‐task stability can help us understand developmental processes, including how risks such as preterm birth affect outcomes. We investigated cross‐task stability of attention control in 32 preterm and 39 term infants. All infants had the same chronological age at time of testing (5 months) but varied in gestational age (GA) at b…
School bonding and ethos in trajectories of offending
BackgroundAspects of the school environment, such as school attachment levels, are linked to adolescent offending. Previous research has not clarified whether a school- or individual-level intervention approach to improving pupil school attachment and commitment is most likely to reduce adolescent offending.AimThe present study assessed the impact of individual- and school-level variables on offending behaviour from ages 14-16 years.SampleThe par…
If You Go Down to the Woods Today
Infants’ emotional reactions to an unusual event were assessed at a simulated birthday party during which two costumed characters enacted a Teddy Bear's Picnic. Two hundred and fifty‐eight firstborn infants in a representative British community sample were observed at a mean age of 12.8 months in the presence of their parents and other participating families, in a laboratory sitting room decorated with balloons and banners. The picnic scenario wa…
PP42 The Influence of Parental Monitoring and School Environment on Adolescent Alcohol Use
Background The importance of social determinants of adolescent health behaviour such as alcohol use has stimulated interest in family and school environments that may act as risk or protective factors. This study looked at characteristics of schools and parents, and how they influence young people’s alcohol use. Methods The Belfast Youth Development Study began in 2000. It surveyed secondary school children annually for five years of compulsory s…
A longitudinal analysis of estimation, counting skills, and mathematical ability across the first school year
In response to claims that the quality (and in particular linearity) of children's mental representation of number acts as a constraint on number development, we carried out a longitudinal assessment of the relationships between number line estimation, counting, and mathematical abilities. Ninety-nine 5-year-olds were tested on 4 occasions at 3 monthly intervals. Correlations between the 3 types of ability were evident, but while the quality of c…
Identifying early signs of aggression
Our aim was to develop an age‐appropriate measure of early manifestations of aggression. We constructed a questionnaire about normative developmental milestones into which a set of items measuring infants' use of physical force against people and expressed anger were included. These items comprise the Cardiff Infant Contentiousness Scale (CICS). Evidence for the reliability and validity of the CICS is provided from analyses of a sample of N =310 …
