Although 10 studies have been published on the empirical overlap of the Adult Attachment Interview (AAI) and measures of self-reported attachment style, results in this literature have been inconsistently interpreted in narrative reviews. This report was designed as a rapprochement of the AAI and attachment style literatures and includes 3 studies. Study 1 (combined N = 961) is a meta-analytic review showing that by J. Cohens (1992) criteria (mean r = .09), the association between AAI security and attachment style dimensions is trivial to small. Study 2 (N = 160) confirms meta-analytic results with state-of-the-art assessments of attachment security and also examines attachment dimensions in relation to the Big 5 personality traits. Finally, Study 3 is an investigation of 50 engaged couples that shows that developmental and social psychological measures of attachment security predict somewhat distinct--though theoretically anticipated--aspects of functioning in adult relationships.

This report was designed to clarify links among self-reports of psychiatric symptomatology, stress, and adult attachment insecurity, as operationalized using measures drawn from both the developmental and social psychological literatures. Based on a sample of 160 college students, this study demonstrated that insecurity reflected in the Adult Attachment Interview (AAI) was associated with self-reports of psychiatric symptomatology principally for individuals experiencing high levels of life stress (consistent with a diathesis-stress model) whereas self-reports of attachment-related avoidance and anxiety correlated robustly with psychopathology under conditions of both relatively high and low life stress (consistent with a risk model). Results provide further evidence that social psychological and developmental approaches to the assessment of adult attachment-related variation are associated with domains of adaptation central to Bowlbys account of human development in empirically distinct ways.

This study examined parenting as a function of child medical risks at birth and parental genotype (dopamine D4 receptor; DRD4). Our hypothesis was that the relation between child risks and later maternal sensitivity would depend on the presence/absence of a genetic variant in the mothers, thus revealing a gene by environment interaction (GXE). Risk at birth was defined by combining risk indices of childrens gestational age at birth, birth weight, and admission to the neonatal intensive care unit. The DRD4-III 7-repeat allele was chosen as a relevant genotype as it was recently shown to moderate the effect of environmental stress on parental sensitivity. Mothers of 104 twin pairs provided DNA samples and were observed with their children in a laboratory play session when the children were 3.5 years old. Results indicate that higher levels of risk at birth were associated with less sensitive parenting only among mothers carrying the 7-repeat allele, but not among mothers carrying shorter alleles. Moreover, mothers who are carriers of the 7-repeat allele and whose children scored low on the risk index were observed to have the highest levels of sensitivity. These findings provide evidence for the interactive effects of genes and environment (in this study, children born at higher risk) on parenting, and are consistent with a genetic differential susceptibility model of parenting by demonstrating that some parents are inherently more susceptible to environmental influences, both good and bad, than are others.

Values are considered relatively stable individual characteristics, and there is little research to date on the conditions that underlie value-priorities change. This small-scale short-term longitudinal study tested whether a major life event of war changes the priority that early adolescents assign to values. Thirty-nine Israeli adolescents completed the Schwartz Values Survey on four occasions-at the beginning, middle, and end of the 2006 Israeli-Lebanese war during which their hometown was bombed. As hypothesized, anxiety-based values of tradition, power, and security increased in importance, while conformity values decreased in importance. Anxiety-free values of benevolence, universalism, self-direction, stimulation, and hedonism decreased in importance. Achievement values decreased and then increased in importance. Despite methodological limitations, the findings demonstrate that value development, at least during early adolescence, can take place rather quickly under circumstances of major traumatic events such as war.

Extensive non-maternal childcare plays an important role in children’s development. This study examined a potential coping mechanism for dealing with daily separation from caregivers involved in childcare experience – children’s development of attachments toward inanimate objects. We employed the twin design to estimate relative environmental and genetic contributions to the presence of object attachment, and assess whether childcare explains some of the environmental variation in this developmental phenomenon. Mothers reported about 1122 3-year-old twin pairs. Variation in object attachment was accounted for by heritability (48%) and shared environment (48%), with childcare quantity accounting for 2.2% of the shared environment effect. Children who spent half-days in childcare were significantly less likely to attach to objects relative to children who attended full-day childcare.
