The stability of attachment security from infancy to adolescence and early adulthood: general discussion

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.     

Attachment security in infancy and early adulthood: a twenty-year longitudinal study

Sixty White middle-class infants were seen in the Ainsworth Strange Situation at 12 months of age; 50 of these participants (21 males, 29 females) were recontacted 20 years later and interviewed by using the Berkeley Adult Attachment Interview (AAI). The interviewers were blind to the participants' Strange Situation classifications. Overall, 72% of the infants received the same secure versus insecure attachment classification in early adulthood, K = .44, p < .001. As predicted by attachment theory, negative life events-defined as (1) loss of a parent, (2) parental divorce, (3) life-threatening illness of parent or child (e.g., diabetes, cancer, heart attack), (4) parental psychiatric disorder, and (5) physical or sexual abuse by a family member-were an important factor in change. Forty-four percent (8 of 18) of the infants whose mothers reported negative life events changed attachment classifications from infancy to early adulthood. Only 22% (7 of 32) of the infants whose mothers reported no such events changed classification, p < .05. These results support Bowlby's hypothesis that individual differences in attachment security can be stable across significant portions of the lifespan and yet remain open to revision in light of experience. The task now is to use a variety of research designs, measurement strategies, and study intervals to clarify the mechanisms underlying stability and change.     

Continuity and discontinuity of attachment from infancy through adolescence

This study reports relations between infant Ainsworth Strange Situation classifications, negative life events, and Adolescent Attachment Interview classifications. Overall, the stability of secure versus insecure classifications was 77%, and infant attachment classification was a significant predictor of adolescent attachment classification. Chi-square analyses indicate that negative life events are significantly related to change in attachment classification. The sample (n = 30) is drawn from the Family Lifestyles Project (FLS), an ongoing longitudinal study of children's development within the context of nonconventional family lifestyles. The distribution of family lifestyles within this study, unlike those in the full FLS sample, represent a higher proportion of conventional two-parent families (40%). There were no differences between adolescents reared in conventional or nonconventional families in the distribution of adolescent attachment security, the experience of negative life events, or the continuity of attachment from infancy through adolescence.     

Interest change and continuity from early adolescence to middle adulthood

The present paper discusses the continuity and change of individuals’ vocational interests by reviewing recent research on interest development across the life course. Five forms of change and continuity were proposed to adequately describe interest development. The developmental trajectory of interests based on a recent meta-analysis by Low, Yoon, Roberts, and Rounds (2005) was presented. Mechanisms resulting in change and continuity are discussed within a biopsychosocial context. Implications for understanding the way interests can simultaneously change and become stable were presented.     

A developmental-genetic analysis of common fears from early adolescence to early adulthood

A 51-item fear survey was administered to more than 2,600 adolescents and adults, including m ore than 400 pairs of like-sex twins, to examine developmental patterns and genetic influences on common fears. Raw data were age-sex standardized and subjected to factor analysis, and preliminary analyses of the factor scores documented both age and genetic effects. Some fears habituate with age; others exhibit sensitization; and, for some fears, intensity is uniform across development. Genetic effects were found for all factors, but the magnitude of such effects varied. Based on these initial analyses, developmental patterns of genetic and environmental influences on self-assessed fears were examined in 354 pairs of like-sex twins, ages 14-34. Hierarchical multiple regression was used to predict a twin's fearfulness from the co-twin's fear, the age and zygosity of the twin pair, and the interactions of these 3 predictors. For all fear factors, co-twin's score and the interaction of co-twin's score with pair zygosity significantly contributed to the prediction of a twin's fearfulness, but the magnitude of both effects varied for different fears. For 2 fear factors, Personal Death and Loved One's Misfortunes, 3-way interactions of co-twin's score, age, and zygosity were observed. The findings suggest significant genetic modulation of developmental patterns in the acquisition and maintenance of some adaptive fears.     

Stability and change in attachment security across adolescence

This study examined both continuity and familial, intrapsychic, and environmental predictors of change in adolescent attachment security across a 2-year period from middle to late adolescence. Assessments included the Adult Attachment Interview, observed mother-adolescent interactions, test-based data, and adolescent self-reports obtained from an ethnically and socioeconomically diverse sample of moderately at-risk adolescents interviewed at ages 16 and 18. Substantial stability in security was identified. Beyond this stability, however, relative declines in attachment security were predicted by adolescents' enmeshed, overpersonalizing behavior with their mothers; depressive symptoms; and poverty status. Results suggest that although security may trend upward for nonstressed adolescents, stressors that overwhelm the capacity for affect regulation and that are not easily assuaged by parents predict relative declines in security over time.     

Developmental patterns in security of attachment to mother and father in late childhood and early adolescence: associations with peer relations

This study examined developmental differences in two dimensions of attachment security (parental availability and child dependency on parents) in late childhood (N = 274) and early adolescence (N = 267) and their association with peer relations. Children's perceptions of mother's availability and boys' perceptions of father's availability did not differ as a function of age. Dependency on parents, however, decreased with age. Findings highlight the importance of distinguishing between parental availability and reliance on parental help when measuring attachment developmentally. Children's reports of positive friendship qualities and lack of conflict in their best friendships were related to attachment to both mother and father, whereas the presence of a reciprocated friendship and popularity were not. Father availability was a particularly important predictor of lower conflict with best friends. Findings indicate that the quality of parent-child attachment generalizes primarily to the quality of children's close peer relations.     

Genetic influences on personality from infancy to adulthood

Recent behavior-genetic studies of personality are reviewed. These studies are first organized according to their subjects' age and then interpreted by emphasizing their developmental implications. Although certain discrepancies have arisen from the use of questionnaire versus laboratory assessments and twin studies as opposed to adoption designs, some consensus may be emerging. Research has moved beyond mere demonstration of heritable sources of variation in the great majority of personality measures. This overview of the literature documents (1) the demonstration of genetic bases for stability of certain personality dimensions, (2) evidence suggesting that the most influential environmental sources of variation are those not jointly experienced by family members, and (3) continuing controversy regarding the convergence of genetic results for different assessment strategies and different developmental periods. Clarifying the nature of the interplay between developmental processes and gene action is now a major task for developmental behavioral geneticists who study personality and temperament.     

Attachment behavior, attachment security, and temperament during infancy

In summary reviews and empirical research, investigators have suggested that attachment classifications derived from the Ainsworth Strange Situation may reflect variations along dimensions of temperament as well as, or perhaps instead of, individual differences with respect to infant-mother attachments. In this study, relations between temperament dimensions from the Infant Temperament Questionnaire (Revised) and Strange Situation behaviors were evaluated. Relations between the behavioral style scores and the categories of attachment quality were also tested. The hypothesis that temperamental difficulty would be related to negative emotionality, as indexed by infant distress during separation (but not during the reunions), was tested and supported. Neither the behavioral style dimensions nor the temperamental diagnoses (e.g., "easy" vs. "difficult") were associated significantly with attachment classifications. The results are consistent with previous findings that temperament measures do not predict attachment security. Nevertheless, certain behaviors indexing negative emotionality that may be observed in the context of the Strange Situation are related to temperamental variability.     

Attachment from infancy to early adulthood in a high-risk sample: continuity, discontinuity, and their correlates

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.     

Small-group collaboration and individual knowledge acquisition: The processes of growth during adolescence and early adulthood

Research into small-group collaboration during middle to late childhood shows that while individual understanding can be promoted through exchanging differing opinions, the joint analyses that groups construct while collaborating play a tangential role. Individuals may or may not accept these constructions depending upon processes of reflection and reconciliation that are triggered through difference and sometimes occur post-group. Recognizing a dearth of research with older participants (together with inconclusive suggestions that collaborative constructions may become more significant with age), the reported study examines the impact of small-group collaboration during adolescence and early adulthood. Forty-six pairs of students aged between 10 and 22 years worked on a computer-presented task that required them to discuss and predict the trajectories objects follow when they fall from stationary or moving carriers. Associations between group dialogue and post-test performance confirmed a key role for differing opinions while collaborative constructions turned out to have little relevance.     

Attachment,self-esteem and test anxiety in adolescence and early adulthood

The purpose of this study was to assess how attachment dimensions (anxiety and avoidance), self-esteem, and three subscales of test anxiety – cognitive obstruction, social derogation and tenseness are related in two age groups: adolescents and college students. Participants (N?=?327) completed relevant questionnaires. Results showed that college students revealed higher test anxiety than did high school students on the cognitive obstruction and tenseness scales, whereas high school students revealed higher social derogation than college students. Anxious attachment was related to all three sub-scales of test anxiety and avoidant attachment was related to cognitive obstruction among college students and to tenseness among high school students. Most of the correlations between anxious attachment and test anxiety were mediated by self-esteem among high school students. The mediation ability of self-esteem was weaker among college students.     

A secure base in adolescence: markers of attachment security in the mother-adolescent relationship

This study sought to identify ways in which adolescent attachment security, as assessed via the Adult Attachment Interview, is manifest in qualities of the secure base provided by the mother-adolescent relationship. Assessments included data coded from mother-adolescent interactions, test-based data, and adolescent self-reports obtained from an ethnically and socioeconomically diverse sample of moderately at-risk 9th and 10th graders. This study found several robust markers of adolescent attachment security in the mother-adolescent relationship. Each of these markers was found to contribute unique variance to explaining adolescent security, and in combination, they accounted for as much as 40% of the raw variance in adolescent security. These findings suggest that security is closely connected to the workings of the mother-adolescent relationship via a secure-base phenomenon, in which the teen can explore independence in thought and speech from the secure base of a maternal relationship characterized by maternal attunement to the adolescent and maternal supportiveness.     

Experience of sexual abuse in childhood and abortion in adolescence and early adulthood

ObjectiveThe present study examined the associations between the experience of sexual abuse in childhood (CSA) and the number of abortions in adolescence and early adulthood.MethodA 25-year prospective longitudinal study of the health, development, and adjustment of a birth cohort of 1,265 New Zealand children (630 females). Measures included assessments of experience of CSA using retrospective data gathered at ages 18 and 21, self-reported abortions from ages 15 to 25, measures of childhood socio-economic disadvantage, family stability, family functioning, experience of childhood physical abuse, and pregnancy in adolescence and early adulthood.ResultsSeverity of CSA experience was significantly (p < .01) associated with an increasing rate of abortions during ages 15–25. Adjustment of the association for potentially confounding factors from childhood reduced the magnitude of the association, but it remained marginally statistically significant (p < .10). However, controlling for the mediating effects of pregnancy risk in adolescence and early adulthood reduced the association between experience of CSA and abortion to statistical non-significance (p > .70).ConclusionsThe current study suggested that the association between experience of CSA and increased rates of abortion was mediated by the increased rates of pregnancy associated with CSA experiences. The results suggest a causal chain in which experience of CSA leads to increased rates of pregnancy, which in turn leads to increased rates of abortion.

Maltreatment experience in childhood and average excess body mass from adolescence to young adulthood

BackgroundPrior studies have suggested maltreatment is a strong predictor of later weight outcomes, such that maltreatment experiences in childhood increase the likelihood of being overweight or obese in adulthood. Estimates of this relationship may be biased due to: 1) inadequate selection of covariates; 2) improper operationalization of child maltreatment; and 3) restricting analyses to cross-sectional outcomes.ObjectivesEvaluate how latent classes of child maltreatment experiences are associated with a longitudinal BMI measure from adolescence to adulthood.ParticipantsData from the National Longitudinal Study of Adolescent to Adult Health.MethodsWe evaluated how previously developed latent classes of child maltreatment experiences were associated with average excess BMI from adolescence to adulthood using multivariate linear regression.ResultsIn the unadjusted model, individuals in the poly-maltreatment class (b = 0.46, s.e. = 0.20) and individuals who experienced adolescent-onset maltreatment (b = 0.36, s.e. = 0.11) had higher average excess BMI compared to individuals in the no maltreatment class. After adjusting for confounders, the relationship between poly-maltreatment and average excess BMI abated, whereas the relationship between adolescent-onset maltreatment and average excess BMI sustained (b = 0.28, s.e. = 0.11).ConclusionsContrary to previous findings, our analyses suggest the association between maltreatment experiences and longitudinal weight outcomes dissipates after controlling for relevant confounders. We did find a relationship, however, between adolescent-onset maltreatment and average excess BMI from adolescence to adulthood. This suggests the importance of maltreatment timing in the relationship between maltreatment and weight.
