Dissociative behaviors and their relation to both the self and self-organization were examined
using the developmental psychopathology perspective in a prospective longitudinal study of
high-risk children. Participants were 168 young adults (n = 79 females, n =
89 males, age = 18–19 years) considered high-risk for poor developmental outcomes at
birth due to poverty. The present study investigated whether trauma, sense of self, quality of early
mother–child relationship, temperament, and intelligence were related to dissociative
symptomatology measured at four times across 19 years. Findings were (a) age of onset,
chronicity and severity of trauma were highly correlated and predicted level of dissociation; (b)
both the avoidant and disorganized patterns of attachment were strong predictors of dissociation;
(c) dissociation in childhood may be a more normative response to disruption and stress, while
dissociation in adolescence and young adulthood may be more indicative of psychopathology; (d)
preliminary support was found for a model proposed by G. Liotti that links disorganized
attachment, later trauma, and dissociation in adulthood; and (e) strong support was found for N.
Waller, F. W. Putnam, and E. B. Carlson's contention that psychopathological dissociation
should not be viewed as the top end of a continuum of dissociative symptomatology, but as a
separate taxon that represents an extreme deviation from normal development.
This study explores the stability of attachment security and representations from infancy to early adulthood in a sample chosen originally for poverty and high risk for poor developmental outcomes. Participants for this study were 57 young adults who are part of an ongoing prospective study of development and adaptation in a high-risk sample. Attachment was assessed during infancy by using the Ainsworth Strange Situation (Ainsworth & Wittig) and at age 19 by using the Berkeley Adult Attachment Interview (George, Kaplan, & Main). Possible correlates of continuity and discontinuity in attachment were drawn from assessments of the participants and their mothers over the course of the study. Results provided no evidence for significant continuity between infant and adult attachment in this sample, with many participants transitioning to insecurity. The evidence, however, indicated that there might be lawful discontinuity. Analyses of correlates of continuity and discontinuity in attachment classification from infancy to adulthood indicated that the continuous and discontinuous groups were differentiated on the basis of child maltreatment, maternal depression, and family functioning in early adolescence. These results provide evidence that although attachment has been found to be stable over time in other samples, attachment representations are vulnerable to difficult and chaotic life experiences.
Current attachment theory hypothesizes that attachment security during infancy influences individual differences in adult representations of attachment. We present three long-term longitudinal studies using three different samples relevant to this hypothesis. Each study assesses infant attachment by using the Ainsworth Strange Situation and adult attachment by using the Berkeley Adult Attachment Interview (AAI). Attachment security was significantly stable in the first two studies. Discontinuity in all three studies was related to negative life events and circumstances. Comparison of the results across these complementary studies affords a degree of replication and sheds light on alternative interpretations. Various mechanisms underlying the stability and instability of attachment security are discussed.
This longitudinal study examines continuity and discontinuity of attachment quality from infancy to late adolescence in a sample of 125 participants considered at birth to be at high-risk due to poverty. Strange Situations were conducted at 12 and 18 months; Adult Attachment Interviews were administered at age 19. Child and maternal characteristics and experiences and observational assessments of the families were explored as correlates of continuity and discontinuity in attachment. Contrary to findings of continuity from low-risk samples, analyses demonstrated no significant overall continuity in attachment security. Disorganized infants were significantly more likely than organized infants to be insecure or unresolved in late adolescence. Additionally, infant disorganization predicted unresolved abuse scores on the AAI for those participants who experienced childhood abuse. Significant correlates of continuity and change spanned a variety of age periods and included infant temperament, maternal life stress, family functioning at pre-adolescence, child maltreatment and features of the home environment. Findings are discussed as supporting the coherence of attachment over time.
For over three decades, critics of the developmental and psychometric paradigms have argued that individual differences are neither stable, coherent, nor clinically significant. The present studies extend a long line of research demonstrating the coherence of individual development in attachment security. They make it clear that attachment security can be stable from infancy through early adulthood and that change in attachment security is meaningfully related to changes in the family environment. The task now is to better understand the roles of cross-age consistency in caregiver behavior and the structure of mental representations of early experience in stability and change.
