Family structure and depressive symptoms in men preceding and following the birth of a child. The Avon Longitudinal Study of Pregnancy and Childhood Study Team.

OBJECTIVE: The prevalence and etiology of pre- and postpartum depressive symptoms in women in a variety of family forms have been well documented, but relatively little research has been conducted on the adjustment of their male partners. The authors' goals in this study were 1) to estimate rates of depression during the pregnancy and 8 weeks following the birth of a child in a large representative community sample of fathers in different family structures and 2) to explore the role of stressful life events, social and emotional support, the quality of the partner relationship, and socioeconomic circumstances. METHOD: This study describes the relations of family setting and other correlates to men's depressive symptoms during the pregnancies (18 weeks gestation, on average) and 8 weeks after the births of children for 7,018 partners of female participants in the Avon Longitudinal Study of Pregnancy and Childhood. RESULTS: Men living in stepfamilies had-significantly higher levels of depressive symptoms before and after the birth than did men in more traditional families. The effect of stepfamily status on depression was mediated by education, life events, social support, social network, and level of aggression in the partnership. CONCLUSIONS: There are similarities in the patterns and correlates of depression after the birth of a child for men and women. These findings point to the importance of family and partnership ecology in the adjustment of men before and after the birth of a child.

Genotype-environment correlations in late childhood and early adolescence: antisocial behavioral problems and coercive parenting.

A key question for understanding the interplay between nature and nurture in development is the direction of effects in socialization. A longitudinal adoption design provides a unique opportunity to investigate this issue in terms of genotype-environment correlations for behavioral problems. As part of the Colorado Adoption Project, adopted children were classified as being at genetic risk (N = 38) or not at genetic risk (N = 50) for antisocial behavior based on their biological mothers' self-report history of antisocial behavior collected prior to the birth of the child. From age 7 through age 12, adoptive parents reported on the negative control, positive parenting, and inconsistent parenting they use in managing their child's behavior. Repeated measures analysis of variance indicated that children at genetic risk were consistently more likely to receive negative parenting from their adoptive parents than children not at genetic risk, indicating an evocative genotype-environment correlation. However, the findings also showed that most of the association between negative parenting and children's externalizing behavior was not explicable on the basis of an evocative gene-environment correlation and that an additional environmentally mediated parental effect on children's behavior was plausible.

Household chaos moderates the link between maternal attribution bias and parenting: Parenting: Science and Practice.

OBJECTIVE: Parents who attribute child misbehavior to children's intentions and dismiss situational factors tend to show more hostility and less warmth in their parenting behavior, and are at greater risk for maltreatment. We extended this literature by investigating the role of household chaos as a moderator of the link between maternal attribution biases and parenting behaviors. DESIGN: The current sample included 160 mothers of 3- to7-year-old children. Mothers provided reports on their attribution biases and household chaos levels. Maternal negativity and positivity were measured using self-reports and observers' ratings. RESULTS: The links between attribution bias and parenting behavior were stronger in more chaotic environments, with the moderating effect of chaos being particularly strong for internal attribution bias. CONCLUSIONS: The findings point to the importance of social cognitive biases in the etiology of maternal behavior in family contexts that lack order and predictability.

Context specificity in stability of hyperactivity-impulsivity.

This paper exemplifies a secondary data analysis of context-specific differences in children's hyperactivity-impulsivity while controlling for informant-specific effects. Participants were boys and girls from the NICHD Study of Early Child Care and Youth Development who were measured in 1(st), 3(rd), and 5(th) grades. Latent factor models were structured using multi-informant reports including mothers, fathers, teachers, and observers. Temporal stability within a context was stronger than cross-context consistency, and the magnitude of longitudinal stability was higher in the home context compared to the school context. Controlling for informant-specific effects resulted in a significantly improved model fit and increased within-context stability. Our findings highlight the importance of considering both context and informant effects when studying longitudinal stability and change in personality development.

Parenting and child behavioral adjustment in early childhood: a quantitative genetic approach to studying family processes.

The aim of this study was to examine environmental and gene-environment processes linking parenting (i.e., affect, control, responsiveness) and preschool children's behavioral adjustment difficulties (e.g., noncompliance, conduct problems) by using bivariate genetic analyses of parents' and observers' ratings. The sample included 120 identical and same-sex fraternal twin pairs (M age = 43 months). Data sources included in-home observations, interviews, and parents' reports. Observers' ratings of children's difficult behaviors included shared and nonshared environmental variance. In contrast, parents' ratings of children's conduct problems showed genetic and nonshared environmental variance. Observer-rated maternal behavior included shared and nonshared environmental variance, although maternal responsiveness also included child genetic variance. Parent self-reported negative and positive affect included shared and nonshared environment as well as child genetic variance. There was no evidence for gene-environment interaction or dominance. Higher levels of difficult behavior and conduct problems covaried with higher levels of maternal negative affect and control and lower levels of maternal positive affect and control. Shared environmental mediation of these correlations was found for observations, whereas genetic and nonshared environmental mediation was found for parents' ratings. In general, estimates of shared environmental variance and mediation were greatest for observational data, and estimates of child genetic variance and mediation were greatest for parent-rated data. The implications of this pattern of findings for genetic research on family processes are discussed.

Annotation: Recent research examining the role of peer relationships in the development of psychopathology.

This Annotation highlights recent research on the role of peer group and friendship factors in the development of psychopathology in childhood and adolescence. Several processes are considered. including peer rejection (e.g., exclusion and victimization), social withdrawal and avoidance of peer interaction, and the socialization of deviant behavior and internalizing problems. The mediating influences of several proximal components are examined, including cognitive-perceptual factors and emotion regulation. In addition, the moderating influences of close friendship, age, gender, ethnicity, and group norms are considered. Several promising avenues for future directions in research are highlighted, including the examination of heterogeneity in developmental processes, further investigation of gender-based norms, and the application of multi-level modeling techniques and gene-environment process models.

An adoption study of the etiology of teacher and parent reports of externalizing behavior problems in middle childhood.

Twin studies of externalizing behavior problems in middle childhood and early adolescence suggest that there is moderate-to-substantial genetic variance and modest-to-moderate shared environmental variance in these behaviors. The present study is novel in three ways: it is a sibling adoption study, it employs both teacher and parent ratings of children's behaviors averaged over five assessments, and it explores aggression and delinquency separately. The sample included 78 adoptive sibling pairs and 94 biologically related sibling pairs in the Colorado Adoption Project. Parents and teachers completed ratings of the children's externalizing behavior problems at ages 7, 9, 10, 11, and 12 years. Boys and adopted children were rated as being somewhat higher in externalizing behavior problems. Sex differences in delinquency were more pronounced in adoptive than in nonadoptive families. Teachers' ratings showed evidence for moderate heritability and no shared environment for aggression and showed modest shared environment for delinquency. Parents' ratings showed evidence for moderate amounts of heritability and shared environment for both aggression and delinquency.

Parent concerns in long-term follow-up.

Consideration of the long-term follow-up of at-risk infants must take into account the role of parents and family contexts. Cognitive and social-emotional adaptation for a premature low birthweight infant is a product of complex transactions between biological and environmental risk and ameliorative factors that operate within powerful family and cultural contexts. Parental behaviors, psychosocial functioning, and social cognitions are particularly important in order to understand long-term developmental outcomes for infants as well as other family members. Interventions for high-risk infants have shown that these can be effective in reducing anxiety and concerns among parents and optimizing parent-child relationships.

Child care quality and children's behavioral adjustment: a four-year longitudinal study.

Studies of extensive, full-time child care in infancy and early childhood have shown negative, positive and no effects on children's social-emotional development. The current study explored the prediction of children's behavioral adjustment 4 years after assessments of daycare center quality (e.g. caregiver-child interactions, caregiver-to-child ratios) and of the home and family environment (e.g. parental stress, discipline). Participants included 141 school-age children (73 girls) and their employed mothers (91% Euro-American) who had made use of full-time child care when the children were toddlers or preschoolers. Home environment factors and earlier behaviors were predictive of individual differences in adjustment 4 years later, particularly for maternal ratings of child behaviors. By contrast, indicators of center quality were generally unrelated to mother and teacher ratings of behavioral adjustment.

A genetic study of the family environment in the transition to early adolescence.

The aim of this longitudinal sibling adoption study was to estimate genetic and environmental components of variance in parent- and child-reported measures of the family environment (parental negative affect, negative control, and achievement orientation). Participants included 85 adoptive and 106 nonadoptive sibling pairs from the Colorado Adoption Project. Parents and children completed annual assessments of the family environment when the children were 10, 11, and 12 years old, and genetic and environmental parameter estimates were derived. Genetic influences were found for parent-reported negativity and warmth and child-reported achievement orientation, suggesting child genetic effects on these measures of the family environment. Shared environmental influences were found for parent-reported negativity, inconsistent discipline, warmth, and child-reported positivity. Nonshared environmental variance was substantial for children's ratings, but modest for parents' ratings.

Siblings, parents, and partners: family relationships within a longitudinal community study. ALSPAC study team. Avon Longitudinal Study of Pregnancy and Childhood.

Links between sibling relationships, mother-partner, and parent-child relationships were studied in a longitudinal community sample of 3681 sibling pairs. Individual differences in sibling relationship quality were related to mother-partner affection and hostility assessed 4 years earlier, to contemporary parent-child negativity, and to indices of social adversity. Evidence for both direct and indirect pathways (via parent-child relations) linking mother-partner and sibling relations were found. Comparisons of prediction for non-stepfamilies and stepfather families showed similarities in patterns of association, but also differences: In stepfather families, mother-partner hostility was unrelated to parent-child negativity and sibling relationship quality. Both positivity and negativity towards young siblings decreased with the age of older siblings, and older sisters were more positive than older brothers.

An adoption study of depressive symptoms in middle childhood.

Several twin studies of children and adolescents have found significant heritability of depressive symptoms. In contrast, the sole adoption study of biologically related and biologically unrelated adopted siblings found no evidence for genetic influence. The present study attempts to confirm these results in middle childhood using two adoption designs. The sample, from the Colorado Adoption Project, included 180 adopted children (77 with adoptive siblings) and their biological and adoptive mothers, and 227 nonadopted children (93 with biological siblings) and their mothers. Mothers reported their own neuroticism, and children's depressive symptoms were reported by the parents and by the children themselves. For both the sibling adoption and the parent-offspring designs heritability was negligible, shared environment modest, and non-shared environment substantial, irrespective of child gender. Although the power of the sibling data is low, the combined findings from the two designs suggest that genetic effects on depressive symptoms in childhood may be somewhat smaller than previously estimated in twin studies.

Dimensions and disorders of adolescent adjustment: a quantitative genetic analysis of unselected samples and selected extremes.

One of the fundamental questions for developmental psychopathology concerns the etiological links between the normal and abnormal. To what extent do disorders differ quantitatively or qualitatively from variation in the normal range? Genetic research on the normal and the abnormal differs in terms of concepts, methods, statistics, and target audiences. An approach, referred to as "DF" analysis, provides a framework for integrating these two worlds of genetic analysis. We applied traditional correlational analyses as well as DF (DeFries & Fulker, 1985) analyses to mother and father ratings of adjustment of adolescent siblings in a 3-year longitudinal twin and step-family study. At wave 1, the sample included 720 sibling pairs (average age of 12.9 years for the younger sibling and 14.5 years for the older siblings) and, in wave 2, 395 pairs still living at home. Both correlational analyses of the entire sample and DF analyses of selected extremes suggested moderate genetic influence and modest shared environmental influence for internalizing and externalizing behavior problems. Similar estimates were found for unselected individual differences and selected extreme groups. A framework is proposed that focuses on quantifying the etiologies of disorders (QED) as measured on continuous dimensions.

Children's adjustment and prosocial behaviour in step-, single-parent, and non-stepfamily settings: findings from a community study. ALSPAC Study Team. Avon Longitudinal Study of Pregnancy and Childhood.

The adjustment and prosocial behaviour of 4-year-old children and their older siblings growing up in step-parent or single-parent families, or with two biological parents, was investigated within a longitudinal community study, the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC). Mean differences in mothers' perception of adjustment were found for children in different family settings, with higher levels of problems and lower prosocial scores reported for those in single- and step-parent families than those in non-stepfamilies. Individual differences within each family setting were marked. With the exception of single parenthood, which remained a risk indicator for the 4-year-olds, the contribution of family type to differences in adjustment and prosocial behaviour largely disappeared when account was also taken of negativity in family relationships, maternal age, education level, depressive symptomatology, and history of previous live-in relationships, mothers' support networks, and the family's current financial and housing circumstances. Boys remained more at risk for adjustment difficulties than girls when this range of factors was taken into account. The limitations and implications of these findings on a community sample, a first step in a programme of research into family processes in children's adjustment, are discussed.

Multiple risk factors in the development of externalizing behavior problems: group and individual differences.

The aim of this study was to test whether individual risk factors as well as the number of risk factors (cumulative risk) predicted children's externalizing behaviors over middle childhood. A sample of 466 European American and 100 African American boys and girls from a broad range of socioeconomic levels was followed from age 5 to 10 years. Twenty risk variables from four domains (child, sociocultural, parenting, and peer-related) were measured using in-home interviews at the beginning of the study, and annual assessments of externalizing behaviors were conducted. Consistent with past research, individual differences in externalizing behavior problems were stable over time and were related to individual risk factors as well as the number of risk factors present. Particular risks accounted for 36% to 45% of the variance, and the number of risks present (cumulative risk status) accounted for 19% to 32% of the variance, in externalizing outcomes. Cumulative risk was related to subsequent externalizing even after initial levels of externalizing had been statistically controlled. All four domains of risk variables made significant unique contributions to this statistical prediction, and there were multiple clusters of risks that led to similar outcomes. There was also evidence that this prediction was moderated by ethnic group status, most of the prediction of externalizing being found for European American children. However, this moderation effect varied depending on the predictor and outcome variables included in the model.
