The current study represents the first longitudinal investigation of the potential effects of breastfeeding duration on maternal sensitivity over the following decade. This study also examined whether infant attachment security at 24 months would mediate longitudinal relations between breastfeeding duration and changes in maternal sensitivity over…

We examined the prediction that the interaction between Glucocorticoid Receptor Gene ("NR3C1") methylation, stress, and experienced maternal support predicts anxious and avoidant attachment development. This was tested in a general population sample of 487 children and adolescents (44% boys, M[subscript age] = 11.84, SD[subscript age] =…

Guided primarily by life history theory, this study was designed to identify how and why early exposure to caregiver intimate relationship instability uniquely predicts children's externalizing symptoms in the context of other dimensions of unpredictability characterized by residential and parental job transitions. Participants included 243…

This research examined the child, parent, and family conditions under which attachment disorganization was related to both level and change in externalizing behavior during preschool among a community sample. Using the ordinary least squares regression, we found that attachment disorganization at 12 months significantly predicted children's…

Undergraduates (N = 2,823) at 6 universities were surveyed longitudinally to examine the relevance of student home setting on the transition to university. Preliminary results indicated that rural students seem less likely to attend large, ethnically diverse universities. Hierarchical linear models revealed that "proximal rural" students…

The main objective of the current study was to examine the impact of two child risk factors, i.e. personality and inhibition, and two proximal family risk factors, i.e. parenting and attachment, and the impact of their cumulative effect on later externalizing behavior among young children incurring no distal family risk. Data were collected in a…

Guided by a dyadic view of children's peer behavior, this study assessed actor and partner effects of attachment security and temperament on young children's behavior with an unfamiliar peer. At 33 months of age, child-mother attachment security was assessed via a modified Strange Situation procedure, and parents reported on child temperament…

Parenting style has been extensively analyzed as a contributor to juvenile delinquency in the criminological literature, but no research to date has assessed the prevalence of parenting style changes during adolescence or the influence of such parenting style changes on juvenile delinquency. Drawing from the life course theory, the results show…

This study examined the longitudinal relationship between friendship quality (positive and negative) and school achievement among 228 school-age children (51% girls, M = 8.09, SD = 0.41). A three-wave cross-lagged analysis was used to determine the direction of influence between these domains across school years. Findings revealed that: (a) school…

The aim of the present study was to examine differences in emotion expression and emotion regulation in emotion-eliciting situations in early adolescence from a bio-psycho-social perspective, specifically investigating the influence of early mother-infant attachment and attachment disorganization on behavioural and adrenocortical responses. The…

This study tested the developmental trajectories of career maturity (CM) and parental attachment (PA), the longitudinal influence of both, and gender as a moderator. Findings showed developmental progressions in adolescents' PA and CM over 4 years. The change in PA was positively related to the developmental change in CM. For gender, there was a…

Many school districts have turned attention to school grade configuration as a way to ease student transitions and improve academic performance, however the research base supporting such reforms is limited. Little attention has been given to how and to what degree school attachment influences the relationship between schools' middle level grade…

Research Findings: This study investigates the effect of the early home environment on self-regulation in preschoolers, and how self-regulation relates to later school achievement, while taking into account family resources. Participants were part of the National Institute of Child Health and Human Development's Study of Early Child Care and Youth…

The purpose of this paper is to provide a comprehensive review of the empirical findings on the stability of attachment from infancy through adulthood. More specifically, the paper discusses the longitudinal research concerning the continuity of attachment from infancy to adulthood as well as those studies that have assessed stability within a…

The aim of this prospective study was to identify preschool factors that are associated with children's classroom engagement during their 1st school year. The study was guided by a social-motivational process model that highlights the importance of parent-child and teacher-child relationships in promoting engagement. In preschool, parents and…
