This research explores the stability of attachment representations, assessed by the Attachment Story Completion Task, within early childhood. Hypotheses were also formed about the influence of parenting, externalizing behavior and intelligence quotient (IQ) on the developmental course of children's attachment representations. Data were collected from 358 French-speaking Belgian children. Security and disorganization showed a linear improvement with age. The effect of time on the two growth curves was influenced by the child's externalizing behavior. When language abilities were controlled for in a subsample of referred children for externalizing behavior, the growth in security was found to be influenced by reasoning IQ, but the effects for disorganization were unchanged. The implications of the results for both research and clinical purposes are discussed.© 2013 Elsevier Inc. All rights reserved.The stability of attachment representations has been studied for a long time. Most results indicate that the individual's attachment pattern remains stable over the course of his/her development. However, only a few studies have been devoted to the stability of attachment within childhood. The present study focuses on the stability of children's attachment representations from three to eight years of age, using the French version of the Attachment Story Completion Task (Fr-ASCT; Bretherton, Ridgeway, & Cassidy, 1990) in the context of a three-wave longitudinal study that allows an accelerated design to be used with three cohorts of children : one of three-year-old children (n = 87), one of four-year-old children (n = 103) and one of five-year-old children (n = 105).
Empirical and conceptual studies of attachment stabilityThe stability of attachment has been empirically considered either within or across several developmental time periods, based on either attachment behaviors or attachment representations. Only studies dealing with stability in infancy and childhood are relevant for our purposes, so only these are reviewed below.Studies involving both infants and preschool children have mainly focused on attachment behavior because the rudimentary verbal skills of these children make the measurement of attachment representations difficult. Numerous studies of infants have analyzed the stability of attachment behaviors with the Strange Situation Procedure (SSP; Ainsworth, Blehar, Waters, & Wall, 1978). In this context, children were shown to differ in their balance between exploration and attachment behaviors in distressing situations. Avoidant children tended to minimize their attachment behaviors in favor of their exploration behaviors, whereas ambivalent children tended to maximize their attachment behaviors to the detriment of their exploration behaviors. Secure children achieved an optimal balance between attachment and exploratory behaviors. Authors have reported a wide range of values for the stability of these patterns, with kappas ranging from .14 to .92 (e.g.
