An emerging income differential for adolescent emotional problems.

Background: While there is considerable evidence of income gradients in child and adolescent behaviour problems, evidence relating to children and young people's emotional difficulties is more mixed. Older studies reported no income differentials, while recent reports suggest that adolescents from low-income families are more likely to experience emotional difficulties than their more affluent peers.

Methods: We compared the association between low- versus medium-/high-family income and parent-reported emotional difficulties in 15- and 16-year-olds in three large nationally representative cohorts studied in 1974, 1986 and 1999/2004.

Do historical changes in parent-child relationships explain increases in youth conduct problems?

The coincidence of historical trends in youth antisocial behavior and change in family demographics has led to speculation of a causal link, possibly mediated by declining quality of parenting and parent-child relationships. No study to date has directly assessed whether and how parenting and parent-child relationships have changed. Two national samples of English adolescents aged 16-17 years in 1986 (N = 4,524 adolescents, 7,120 parents) and 2006 (N = 716 adolescents, 734 parents) were compared using identical questionnaire assessments.

The contribution of prenatal and postnatal maternal anxiety and depression to child maladjustment.

Background: The adverse effect of both pre- and post-natal maternal anxiety and depression on the development of offspring is shown by a large body of research. No published studies, however, have simultaneously: (i) controlled for co-occurring prenatal risks that may influence maternal prenatal anxiety and depression; (ii) compared the relative contributions of prenatal and postnatal maternal anxiety and depression on child functioning; and (iii) assessed a full range of child psychopathology and functioning to determine the relative effects of prenatal and postnatal anxiety and depression in the mother.

Method: Using 3,298 mother-offspring pairs, the authors examined these factors in a single-path analytic model.

Do changes in parent mental health explain trends in youth emotional problems?

There is evidence of a long-term rise in the prevalence of adolescent emotional problems in the U.K. and in other countries.

Family hardship, family instability, and cognitive development.

Background: Associations between the characteristics of the family environment, in particular poverty and family structure, and cognitive development are well established, yet little is known about the role of timing and accumulation of risk in early childhood. The aim of this paper is to assess the associations between income poverty, family instability and cognitive development in early childhood. In particular, it tests the relative role of family economic hardship compared with family instability in affecting cognitive functioning at the age of 5 years.

Social cognition and conduct problems: a developmental approach.

Objective: To estimate associations between trajectories of conduct problems and social-cognitive competences through childhood into early adolescence.

Method: A prospective population-based cohort, the Avon Longitudinal Study of Parents and Children (ALSPAC) recruited in the prenatal period (13,988 children alive at 12 months) formed the basis for the current study. Socio-emotional and pragmatic language competences were examined in relation to conduct problem development in a group of 6,047 children with no known autistic-spectrum disorders.

The impact of prenatal maternal risk, fearless temperament and early parenting on adolescent callous-unemotional traits: a 14-year longitudinal investigation.

Objective: Proposals have been submitted to the DSM-V for the addition of a callous-unemotional (CU) specifier for conduct problem (CP) youth (CP/CU). While the addition of such a diagnostic category may aid in the identification of homogeneous CP subtypes, evidence on risks for the development of CP/CU remains limited. The present study sought to examine the extent to which CP/CU in early adolescence could be differentiated by family- and child-based risks from pregnancy to age 4 years.

Associations between diurnal preference, sleep quality and externalizing behaviours: a behavioural genetic analysis.

Background: Certain aspects of sleep co-occur with externalizing behaviours in youth, yet little is known about these associations in adults. The present study: (1) examines the associations between diurnal preference (morningness versus eveningness), sleep quality and externalizing behaviours; (2) explores the extent to which genetic and environmental influences are shared between or are unique to these phenotypes; (3) examines the extent to which genetic and environmental influences account for these associations. method: Questionnaires assessing diurnal preference, sleep quality and externalizing behaviours were completed by 1556 young adult twins and siblings.

ED handoffs: observed practices and communication errors.

Objective: The study objectives were to identify emergency department (ED) handoff practices and describe handoff communication errors among emergency physicians.

Methods: Two investigators observed patient handoffs among emergency physicians in a major metropolitan teaching hospital for 8 weeks. A data collection form was designed to assess handoff characteristics including duration, location, interruptions, and topics including examination, laboratory examinations, diagnosis, and disposition.

Co-occurring problems of early onset persistent, childhood limited, and adolescent onset conduct problem youth.

Background: It is increasingly recognized that youth who follow early onset persistent (EOP), childhood limited (CL) and adolescent onset (AO) trajectories of conduct problems show somewhat varying patterns of risk (in childhood) and adjustment problems (in adolescence and adulthood). Little, however, is known about how other adjustment problems differentially co-develop with the EOP, CL and AO trajectories across the childhood and adolescent years.

Method: Using data from the Avon Longitudinal Study of Parents and Children, an epidemiological, longitudinal cohort of boys and girls, we estimated growth curves for parent-reported hyperactivity, emotional difficulties, peer relational problems, and prosocial behaviors conditional on trajectories of conduct problems (i.

Negative childhood experiences and adult love relationships: the role of internal working models of attachment.

This study investigated links between internal working models of attachment and the quality of adult love relationships in a high risk sample of women (n = 34), all of whom reported negative parenting in childhood. Half of the sample was identified as having a history of satisfying adult love relationships, while the remainder had experienced ongoing adult relationship problems. Measures of internal working models of attachment were made using the Adult Attachment Interview (AAI).

The role of contextual risk, impulsivity, and parental knowledge in the development of adolescent antisocial behavior.

The present study (a) tests main and moderational effects of neighborhood and family risk, and adolescent impulsivity on the development of male and female antisocial behavior (ASB) and (b) examines the extent to which these effects work indirectly through parental knowledge. Adolescents (N = 4,597; 51% male) reported on informal social control in their neighborhoods, their family types, and impulsivity at age 12, and on parental monitoring and ASB at ages 13 and 15 years. Neighborhoods were further defined as risk and nonrisk in economic deprivation by census-level data.

Self-control and its relation to joint developmental trajectories of cannabis use and depressive mood symptoms.

Background: Cannabis use and depressive mood symptoms in adolescence have been found to co-occur. In exploring the nature of this relationship and in the search for mechanisms that explain this link, scholars have postulated the idea for a 'common liability model'. According to this model, the link between cannabis use and depressive symptoms can be explained by an underlying risk factor.

Trends in adolescent emotional problems in England: a comparison of two national cohorts twenty years apart.

Background: Evidence about trends in adolescent emotional problems (depression and anxiety) is inconclusive, because few studies have used comparable measures and samples at different points in time. We compared rates of adolescent emotional problems in two nationally representative English samples of youth 20 years apart using identical symptom screens in each survey.

Methods: Nationally representative community samples of 16-17-year-olds living in England in 1986 and 2006 were compared.

Outcomes of early pubertal timing in young women: a prospective population-based study.

Objective: Early pubertal timing in girls is associated with psychosocial problems throughout adolescence, but it is unclear whether these problems persist into young adulthood. The authors analyzed outcomes in adolescence and young adulthood in girls in a longitudinal study.

Method: The data for this study were from the prospective population-based Great Smoky Mountains Study (N=1,420), which initially recruited children at ages 9, 11, and 13 and followed them into young adulthood.

What's in a disruptive disorder? Temperamental antecedents of oppositional defiant disorder: findings from the Avon longitudinal study.

Objective: Oppositional defiant disorder (ODD) is classified as a disruptive disorder, but shows a wide range of associations with other psychopathology, including internalizing problems. The reasons for these associations are unclear. Here we test the hypothesis that two distinct early temperamental precursors-emotionality and activity-underlie ODD and differentially predict its comorbidities.

Families promote emotional and behavioural resilience to bullying: evidence of an environmental effect.

Background: Bullied children are at risk for later emotional and behavioural problems. 'Resilient' children function better than would be expected given their experience of bullying victimisation. This study examined the role of families in promoting resilience following bullying victimisation in primary school.

The role of callous and unemotional traits in the diagnosis of conduct disorder.

Background: Callous and unemotional (CU) traits might usefully subtype DSM-IV conduct disorder (CD). We investigate this hypothesis in a large, nationally representative sample of 5-16-year-olds. We also examine the characteristics of children with high CU traits but without CD.

A developmental-contextual approach to understanding mental health and well-being in early adulthood.

There is an increasing awareness of the social and economic burden of untreated mental illness. However, the question remains whether the individuals who are not identified as having a mental disorder are mentally healthy and socially functioning. This study aims to examine the sequence of Keyes's (Keyes, C.

Predictive value of callous-unemotional traits in a large community sample.

Objective: Callous-unemotional (CU) traits in children and adolescents are increasingly recognized as a distinctive dimension of prognostic importance in clinical samples. Nevertheless, comparatively little is known about the longitudinal effects of these personality traits on the mental health of young people from the general population. Using a large representative sample of children and adolescents living in Great Britain, we set out to examine the effects of CU traits on a range of mental health outcomes measured 3 years after the initial assessment.

Childhood emotional problems and self-perceptions predict weight gain in a longitudinal regression model.

Background: Obesity and weight gain are correlated with psychological ill health. We predicted that childhood emotional problems and self-perceptions predict weight gain into adulthood.

Methods: Data on around 6,500 individuals was taken from the 1970 Birth Cohort Study.
