Adolescents' relationships to siblings and mothers: a multivariate genetic analysis.

Research has consistently demonstrated that children's behavior toward their siblings tends to resemble interactions occurring in the parent-child relationship. This study examined the relative contributions of genetic and environmental influences to the covariation between sibling relationships and mother-adolescent relationships. Reported and observed family interactions were assessed for 719 same-sex sibling pairs of varying degrees of genetic relatedness. The covariance between mother-adolescent and sibling interactions was decomposed into genetic, shared, and nonshared environmental components. The overlapping effects of shared environment on the two relationship subsystems explained most of the covariance. Smaller but significant genetic and nonshared environmental effects were also found. The consistency of these findings with family processes, such as modeling, is discussed.     

Environmental Contributions to Adolescent Delinquency: A Fresh Look at the Shared Environment

Few genetically-informative studies have attempted to explicitly identify the shared environmental (i.e., those environmental influences that contribute to sibling similarity) factors now known to contribute to adolescent delinquency. The current study therefore examined whether the parent-child relationship served as one source of these shared environmental influences. Participants were 610 adoptive and biological families from the Sibling Interaction and Behavior Study (SIBS). Parents and adolescents reported on their parent-child conflict and parental involvement with child, and adolescents reported on their own delinquent behaviors. We employed structural equation modeling and supplementary multilevel modeling, finding consistent evidence that the association between delinquency and the parent-child relationship is at least partially shared environmental in origin. Such findings provide an important extension of previous twin studies, as they suggest that passive genotype-environment correlations do not explain earlier findings of shared environmental influences on this association.     

Similarity between parents' and adolescents' levels of individuation.

Intergenerational theories of family functioning and therapy have sparked interest in empirical investigations that test intergenerational relationships. Of particular interest is whether one generation's level of functioning is similar to that of the next generation. This paper presents a test of difference scores that enables researchers to compare related and unrelated dyads, thus creating a comparison group when using only two generations. This procedure is contrasted with correlational findings in testing the hypothesis that adolescents will have a level of individuation similar to that of their parents.     

Children's perceptions of the sibling relationship in middle childhood: Connections within and between family relationships

Although sibling warmth and hostility have been shown to be statistically independent, they are intertwined in children's everyday experiences. We developed a multidimensional characterization of children's perceptions of their sibling relationships and examined differences in other family relationship measures as a function of different combinations of sibling hostility and warmth. Participants included 91 firstborn children between 10 and 11 years of age with younger siblings between 6 and 10 years of age. Children reported their levels of satisfaction, intimacy, and rivalry in their sibling relationships and their satisfaction with parent-child relationships. Parents rated their marriages. As compared with children in families with “affect-intense” sibling relationships (high hostility/high warmth), children in “hostile” sibling relationships (high hostility/low warmth) rated their sibling and parent-child relationships more negatively, and their parents rated their marriages more negatively. Results are discussed in terms of the role of hostility in sibling experiences and the importance of understanding multidimensional patterns in the sibling relationship.     

Cultures of teaching in childhood: Formal schooling and Maya sibling teaching at home

Culture can be thought of a set of shared practices, beliefs, and values that are transmitted across generations through language [Bruner, J. (1990). Acts of meaning. Cambridge, MA: Harvard University Press]. Teaching is one way that culture is transmitted, but forms of teaching vary across cultures and across activity settings within cultures. This article explores the impact of culture on styles of teaching in a place where more than one cultural model of teaching is found: the Zinacantec Maya of Chiapas, Mexico. Zinacantecs have an indigenous model of teaching that applies to the learning of informal tasks, such as making tortillas and weaving. When children go to school, the indigenous model interacts with the model found at school, and this mixed model is transferred back home to sibling interactions. Videotaped ethnographic observations and quantitative discourse analyses reveal cultural patterns in the development of children's teaching.     

Parent-Child Interactions in Anxious Families

A considerable amount of research has examined factors associated with the etiology and maintenance of anxiety disorders in children. The familial nature of anxiety has been well-established, with genetic studies showing that approximately 30% of the variance is accounted for by genetic factors. Research into the family environment documents behavioral differences in interactions between non-anxious parent-child and anxious parent-child dyads, including less granting of autonomy, and parental withdrawal and disengagement. Recent theoretical work in the field of anxiety suggests that attachment models and coercive operant patterns could create a bi-directional coercive interaction pattern, similar to that seen in interactions of parents and aggressive children. The current study investigated parent and child behaviors coded from interaction tasks across four groups based on anxiety status: anxious parent/anxious child, non-anxious parent/anxious child, anxious parent/non-anxious child, and non-anxious parent/non-anxious child to empirically examine hypothesized interactive patterns. The study sample consisted of 158 parent-child (ages 3–12 years) dyads. Results support an interaction between parent and child anxiety on behavior within dyads. The current study provides an important step in identifying processes linked to familial anxiety.

Differential parent-child relationships and adolescent externalizing symptoms: cross-lagged analyses within a monozygotic twin differences design

Research has indicated that differential parental treatment is linked to differences in externalizing symptomology (EXT) across siblings, even those siblings who are genetically identical. However, the direction of causation and longitudinal significance of this relationship remains unclear. Thus, in the present study, the authors examined 486 monozygotic twin pairs, assessed at ages 11, 14, and 17 years, within a cross-lagged twin differences design. Results revealed that differential parent-child conflict at age 11 years uniquely contributed to differential sibling EXT 3 years later but only in the most discordant twin pairs. In the full, unselected sample, this relationship was not significant. These results suggest that markedly different parent-child conflict has an environmentally mediated impact on child behavior through mid-adolescence, findings that yield insights into environmental influences on behavior.     

Bidirectional links and concurrent development of parent-child relationships and boys' offending behavior

This study examined different types of longitudinal associations (i.e., directional links and overlapping developmental changes) between children's delinquency and the quality of parent-child relationships from middle childhood to late adolescence. We used 10-wave interview data of 503 boys, their primary caregivers, and their teachers. Our first aim was to unravel the direction of effects between parent-child relationships and children's offending. Cross-lagged panel models revealed bidirectional links over time between poorer quality parent-child relationships and boys' offending across late childhood (age 7-10), early adolescence (age 10-13) and middle adolescence (age 13-16). Second, we examined the associations between mean changes in delinquency, on the one hand, and mean changes in relationship quality, on the other hand. Although parent-child relationships improved during childhood, their quality decreased in early adolescence and remained stable in middle adolescence. Delinquency increased only in middle adolescence. In five out of six models, the slope factors of relationship quality and offending were strongly correlated, indicating that stronger increases in delinquency were associated with stronger decreases in parent-child relationship quality across childhood, early adolescence, and middle adolescence. The discussion focuses on the theoretical implications of these two types of longitudinal associations.     

Possible confounds and their resolution in multivariate genetic analyses: comment on Bussell et al. (1999)

Assumptions behind the twin, sibling, and stepsibling design used in the Nonshared Environment in Adolescent Development study are considered. The D. A. Bussell et al. (1999) analyses of behavior in relationships indicate effects of both genetic and common-environment factors. Possible real and artifactual sources of the common environment include assortative mating, sibling interaction, failure of the equal environments assumption, and contaminated measures. Another potential source, specific to this study, is the effect of an individual in the mutual ratings of relationship with sibling, which would lead to a larger common-environment effect across variables than within variables. This alternative model did not indicate that there was a mutual rating effect. Univariate analyses confirm that the common-environment effect is present for both sibling and parent-child relationships. Most other potential sources of common environment, such as sibling interaction, do not account for the data.     

Optimal or Typical Performance? The Impact of Instructional Set on the Behavioral Assessment of Parent-Child Interactions

The behavioral assessment of parent-child interactions is an important component of treatment planning and evaluation in many evidence-based parent training programs. However, numerous factors unrelated to the parent-child interaction may add error to the assessment. This study investigated the impact of task instructions on parents’ behaviors during the analogue parent-child interaction observation, the Dyadic Parent-Child Interaction Coding System (DPICS). Forty-eight mother-child dyads were randomly assigned to one of two conditions that differed on level of specificity of instructions. Significant differences were observed between groups, with parents who received specific instructions using more praises during the DPICS tasks. Specific instructions may shift parents’ behaviors toward optimal, rather than typical, interaction patterns and should be considered in the context of the assessment goals.     

Dyadic synchrony among young Latina mothers and their toddlers: The role of maternal and child behavior

Synchronous interactions are an important indicator of parent-child relationship quality with positive implications for child development. Latina adolescent mothers face several demographic challenges that place them at risk for less synchronous interactions. To identify factors that may facilitate more optimal parent-child relationships in this population, our study examined maternal sensitivity and children’s behavioral styles as joint predictors of dyadic synchrony among young Latina mothers and their toddlers. Mother-toddler dyads (N = 170) were observed interacting across different tasks, and toddlers’ behavior was observed during the administration of a developmental test. Results of multivariate regressions revealed additive effects of maternal sensitivity and child behavioral styles (i.e., dysregulation and positive attentional control). Maternal sensitivity related to higher dyadic synchrony for the entire sample. Positive attentional control was related to higher dyadic synchrony for mother-daughter dyads only. Although no gender differences in dyadic synchrony or the behavior style variables emerged, the relative contribution of maternal and child factors differed by child gender, suggesting that mothers may have responded differently to similar behavior and affect displayed by boys and girls. The findings provide insights regarding factors that contribute to dyadic synchrony in this understudied population and emphasize the need to consider child gender when studying parent-child interactions in young Latina families.     

Individual characteristics,child-mother and child-younger sibling interactions of 4-year-olds

This paper is concerned with the relations between the individual characteristics (Temperament, Locus of Control, Self-concept) of 4-year-olds, child-mother and child-sibling interactions. The temperamental characteristics Active and Moody, and the Self-concept categories Worrying/Cross and Likes to be Alone, had generally similar relations to child-mother and child-sibling interactions, but the other characteristics did not. The relations between child-mother and child-sibling interactions did not support either the hypothesis that a ‘good ’ child-mother relationship leads to ‘good ’ interactions with a sibling, or that firstborns compensate for a ‘poor ’ child-mother relationship with a ‘good ’ sibling one. The relations were more complex than either of these hypotheses would suggest, but made intuitive sense.     

Self-control,parental crime,and discipline across three generations

The objective of this study is to examine the relationships between self-control, parental crime, and use of discipline across three generations. Data spanning 30 years from the National Longitudinal Survey of Youth, are analyzed using Structural Equation Modeling. This study focuses on whether different types of discipline used by parents predict the self-control of each successive generation. We also examine whether self-control and criminal activities of parents are predictive of parenting and resulting self-control of children. We find that discipline has a weak relationship to self-control but that parental crime and self-control do relate to the self-control of later generations.     

WOMEN'S AMBITIONS: A THREE-GENERATIONAL STUDY

The purpose of this study was (a) to describe the nature of women's ambitions across three generations of women within families, (b) to assess the women's perceptions of factors influencing their ambitions, and (c) to determine their estimates of success in attaining their ambitions. In addition, influence of the generations upon each other and relative similarity of ambitions within families versus within generations was evaluated. Subjects were 10 women who were seniors at a large, midwestern state university, their mothers, and their maternal grandmothers. The most prevalent categories of ambitions across all generations were marriage/family, educational, and vocational. Change in women's roles and a trend toward greater economic affluence across generations had the greatest influence on ambition development and attainment. Influences of one generation on another were apparent for adjacent, but not for nonadjacent, generations. In general, women's ambitions were more similar within generations than within families.

How Gene-Environment Interactions Shape Biobehavioral Development: Lessons From Studies With Rhesus Monkeys

Recent research has found marked individual differences in patterns of rhesus monkey biobehavioral development throughout the life span. Approximately 20% of monkeys growing up in naturalistic settings consistently display unusually fearful and anxious-like behavioral reactions to novel, mildly stressful social situations throughout development; another 5%-10% are likely to exhibit impulsive and/or inappropriately aggressive responses under similar circumstances. These distinctive behavioral patterns and their biological correlates appear early in life and remain remarkably stable from infancy to adulthood. Both genetic and experiential mechanisms are implicated not only in the expression of these patterns but also in their transmission across successive generations of monkeys. For example, a specific polymorphism in the serotonin transporter gene is associated with deficits in infant neurobehavioral functioning and in juvenile and adolescent control of aggression and serotonin metabolism in monkeys that experienced insecure early attachments but not in monkeys that developed secure attachment relationships with their mothers during infancy (maternal buffering). Moreover, because the attachment style of a monkey mother is typically "copied" by her daughters when they grow up and become mothers themselves, similar buffering is likely to occur for the next generation of infants carrying that specific polymorphism.     

The impact of infant-directed videos on parent-child interaction

This study assessed whether infant-directed videos designed to promote parent-child interactions actually support such engagement. Parents watched videos from the Baby Einstein or the Sesame Beginnings series for 2 weeks at home with their 12- or 18-month-old infants. Baby Einstein encourages parents to label objects and actions; Sesame Beginnings models activities in which parents can engage with their children. A control group was not provided videos for home viewing. In laboratory sessions, parent-child interactions were recorded during free play without TV, during the presentation of one of the videos, and immediately after watching. During viewing, interactions decreased in quantity and quality across groups; however, parents used video content as a basis for interaction. Coviewing Sesame Beginnings at home was positively associated with quantity of parent-child interaction during the initial free-play session. Furthermore, the quantity and quality of interactions were greater immediately following viewing of Sesame Beginnings than with Baby Einstein.     

Personally relevant vs. nationally relevant memories: An intergenerational examination of World War II memories across and within Belgian French-speaking families

We examined whether and how memories and knowledge of World War II (WWII) transmit across generations. We recruited five French-speaking Belgian families and interviewed one member from each generation. As the oldest generation had to be alive during WWII, their interviews constituted “memories” while the interviews of the middle and youngest generation constituted “knowledge”, as they were not alive during WWII. Each individual was asked about four WWII events specific to Belgium (two of which were likely to be controversial, i.e., collaboration and the Royal Question), and the source from which they learned about these four events: was it communicatively (e.g., through familial discussions) or culturally (e.g., social artifacts: books, school, monuments, etc.) transmitted? Our results suggest that transmission of memories and knowledge across generations was limited. The oldest generation, who were children during the war, and the middle generation knew about the WWII events discussed in the interviews, particularly the oldest generation. The youngest generation, however, did not. Furthermore, for the most part, all generations, in discussing memories of the WWII events, told nationally relevant memories. If the oldest generation discussed personally relevant memories, these memories sometimes transmitted to the middle generation and rarely to the youngest. We discuss these results in terms of Assmann and Czaplicka, 1995, Assmann, 2011) distinction between communicative and cultural memory.
