Mother-infant attachment in adoptive families.

Data from 2 separate samples using the Strange Situation paradigm were combined to assess the quality of attachment relationships in adoptive and nonadoptive mother-infant pairs. Infants were between 13 and 18 months at the time of observation. Results indicated no differences in mother-infant attachment between nonadopted and intraracial adopted subjects or between intraracial and interracial adopted subjects. Interracial adoptive mother-infant pairs did show a higher incidence of insecure attachment in comparison to nonadoptive pairs. Mothers of interracial adopted infants also were less comfortable having others care for their babies and perceived less emotional support from extended family and friends for their decision to adopt a child prior to the actual adoption than did other mothers. No relation was found, however, between quality of mother-infant attachment and either perceived social support, infant developmental quotient, infant temperament, number of foster homes experienced by the infant, or infant's age at the time of adoption placement. It was suggested that the higher incidence of psychological problems found among adoptees in middle childhood and adolescence cannot be explained in terms of insecure attachment relationships during the infancy years.

Discriminant validity of the adult attachment interview.

The Adult Attachment Interview is a semi-structured interview developed to investigate adults' attachment representations. Subjects are asked to describe their parents as caregivers, explain these descriptions, describe how their parents typically responded to distress, and discuss their current relationships with their parents. They are also asked to describe any significant losses and/or instances of abuse during childhood. Scoring focuses on the accessibility of early experiences to memory and the coherence and plausibility of the subject's narrative. Discriminant validity is always an important issue with such measures because IQ and other cognitively loaded variables offer plausible alternative interpretations or represent important correlates that should be treated as covariates when the measure is used. In addition, complex, multifaceted interviews always pose the risk of assessing general social adjustment rather than a more narrowly defined construct. This study examines the discriminant validity of the AAI vis(-)à-vis intelligence, social desirability, discourse style, and general social adjustment in a sample of 53 native-English-speaking, married women with preschool children. They were assessed with the AAI, a written IQ test, the Social Adjustment Scale, the Employment Experience Interview (discourse style), and a measure of social desirability. There were modest but significant correlations with IQ scores and social adjustment. There was no relation between AAI classifications and discourse style or social desirability. These results substantially strengthen the case for interpreting the AAI as an attachment-related measure.

In search of the absent father--meta-analyses of infant-father attachment: a rejoinder to our discussants.

In our meta-analysis on sensitivity and attachment, studies on the role of the father in the development of infant attachment were excluded. In this rejoinder to our discussants, we present new meta-analytic evidence on the association between paternal sensitivity and infant-father attachment (combined effect size r[544] = .13; k = 8 studies; N = 546 families), and on the association between infant-mother and infant-father attachment (overall correlation phi = .17; k = 14 studies; N = 950). Combining the findings from several earlier meta-analyses, we present a data-based model of attachment within the family system.

Inhibition of adherence of Candida albicans and Candida dubliniensis to a resin composite restorative dental material by salivary secretory IgA and monoclonal antibodies.

OBJECTIVE: The attachment of Candida to oral surfaces is a crucial step in the colonization of the oral cavity and the eventual development of oral diseases caused by this microorganism. Inhibition of adhesion is one of the strategies currently studied to prevent Candida infections. The main objective of this study was to investigate the inhibitory effect of the human salivary components on the adherence of Candida albicans and C. dubliniensis to Herculite, a widely used resin composite restorative dental material. We have also investigated the influence on the adherence of three monoclonal antibodies (mAbs) directed against C. albicans cell wall antigens. DESIGN: The adhesion of three strains of C. albicans and one strain of C. dubliniensis was studied by a visual method after incubating the fungus and the resin in presence and in absence of human whole saliva, secretory immunoglobulin A (sIgA) and three mAbs directed against C. albicans cell wall surface antigens. RESULTS: Adherence of C. albicans was inhibited by whole saliva (41.7%), salivary sIgA (55.7%) and the salivary components that bind to the cell wall (36.7%). Whole saliva significantly reduced the adhesion of C. dubliniensis to Herculite to 45.3% of the control level. Saliva previously adsorbed with fungal cells or sIgA depleted saliva had no effect on adherence. An inhibition in the adhesion of C. albicans and C. dubliniensis to Herculite similar to that shown by whole saliva was also observed when mAbs C7 and 26G7 were used. However, mAb 21E6 increased adhesion of all the strains to Herculite. CONCLUSIONS: The results suggest that sIgA, as well as whole saliva, are important in blocking adherence of C. albicans and C. dubliniensis to Herculite and that this effect can be reproduced with mAbs directed against the cell wall surface of C. albicans.

Plasma cortisol and vocalization responses of postweaning age guinea pigs to maternal and sibling separation: evidence for filial attachment after weaning.

Postweaning guinea pigs housed with their mother and littermates since birth vocalized more and exhibited greater increases in plasma cortisol levels when placed for 1 hr into a novel test cage alone than they did when tested in the identical fashion with the mother present. These responses were apparent beyond 50 days of age, but had waned by 90 days of age. When tested with a familiar sibling cagemate, postweaning guinea pigs emitted fewer vocalizations than when tested alone but exhibited no less of an elevation of plasma cortisol levels. These results were obtained regardless of whether the subjects had been housed with mother and littermates from birth until the time of testing or with mother and littermates until weaning and then just the single sibling cagemate until the time of testing. The present findings closely approximate those seen in preweaning guinea pigs during tests of maternal and sibling separation, and indicate that guinea pigs can continue to exhibit a specific attachment to the mother beyond the time of weaning.

Generic aspects of primate attachments: parents, offspring and mates.

We examine behavioral and physiological aspects of primate emotional attachments in the context of four relationships: infant-to-parent, parent-to-infant, and adult male-to-female and adult female-to-male in a monogamous New World species. Emotional attachments in each of these relationships show striking similarities at a basic functional level. The nature of these similarities suggests that they are produced by the same psychoneuroendocrine core, which appears to be present in all mammals. We also consider the development of each of kind of attachment. In contrast to fundamental similarities in the expression of attachment, their development in each case appears to be based on distinct, species-typical dispositions and constraints.

The Preschool Assessment of Attachment: construct validity in a sample of depressed and nondepressed families.

Construct validity of the newly developed Preschool Assessment of Attachment (PAA) was examined in a sample of depressed and nondepressed mothers and their preschoolers, focusing on attachment related differences in children's general caregiving environments, maternal psychosocial functioning, and child behavior during interactions with mother. Mothers of secure children were more emotionally and verbally responsive to their children than were mothers of insecure children, and secure children were emotionally more positive to their mothers than were insecure children. Mothers of secure children also reported higher levels of social supports than did mothers of insecure children. Finally, dyads with children who lacked unitary, coherent attachment strategies (i.e., anxious depressed, defended/coercive, and insecure other) showed the worst functioning in all domains relative to all other attachment groups. Similar but slightly less robust findings were obtained with socioeconomic variables statistically controlled. These results lend support to the PAA as a valid system for the conceptualization and measurement of quality of attachment among preschoolers. Future research applications with the PAA are discussed.

Multiple attachment relationships within families: mothers and fathers with two young children.

Security of attachment between mothers and fathers and their 2 children was examined in 41 maritally intact families. Strange Situation assessments of attachment security for the younger children (mean age = 1 year 10 months), Attachment Q-sort ratings of the older children (mean age = 4 years 8 months), and ratings of parental caregiving behavior of both children were obtained. Younger and older children developed concordant attachments to both parents. Parents were consistent in their caregiving behavior toward their 2 children. However, parents were not congruent in their attachment to their 2 children. Associations were found between maternal caregiving and attachment only in the younger group. The results support the idea that parental caregiving behavior accounts for only modest portions of the variance in attachment security; evolving attachments integrate developmental inputs from the children and the caregivers in the network of early family relationships.

Effects of adult attachment and presence of romantic partners on physiological responses to stress.

The effects of presence vs. absence of a romantic partner on psychophysiological responses to a stressful laboratory situation were examined in a sample of 35 college women involved in serious dating relationships. Participants performed a standard psychological stress task both in the presence and in the absence of their romantic partners, with order counterbalanced across participants. Heart rate and blood pressure were measured in each of these conditions during both baseline and task performance periods. Avoidant (but not secure) and anxious (but not nonanxious) participants displayed heightened physiological responses across all conditions and periods if the partner-absent condition came first rather than second. Discussion focuses on 2 explanations for the findings in terms of (a) the anxiety-reducing function of attachment relationships and (b) the anxiety-producing effect of separation in a stressful situation.

The affective component of the secure base schema: affective priming with representations of attachment security.

Using an affective priming procedure (S. T. Murphy & R. B. Zajonc, 1993), 7 studies examined the effects of the contextual activation of representations of attachment security (secure base schema) on the evaluation of neutral stimuli under either neutral or stressful contexts. In all the studies, participants also reported on their attachment style. Results indicated that the subliminal priming of secure base representations led to more positive affective reactions to neutral stimuli than did the subliminal priming of neutral or no pictures under both neutral and stressful contexts. Although the subliminal priming of positively valued, attachment-unrelated representations heightened positive evaluations under neutral contexts, it failed to elicit positive affect under stressful contexts. The results also revealed interesting effects of attachment style. The discussion focuses on the affective component of the secure base schema.

Adolescents' attachment representations and developmental tasks in emerging adulthood.

The association between attachment representations and adolescents' coping with 3 developmental tasks of emerging adulthood-leaving home, advancing in the capacity for mature intimacy, and developing individuation-was examined. Israeli male adolescents (N = 88) were administered the Adult Attachment Interview during their high-school senior year. A year later, they and their friends reported on the adolescents' adjustment to mandatory military service. Three years later, participants and their parents reported on the adolescents' capacity for intimacy using an in-depth interview and on their individuation. An autonomous state of mind was associated with better coping with basic training and with a higher capacity for mature intimacy but was not associated with markers of individuation. The results highlight the importance of attachment representations in shaping an individual's developmental trajectory.

Attachment, sleep quality, and depressed affect.

This study examined the role of attachment insecurity in sleep problems among married adults (N=78 couples). Using the Pittsburgh Sleep Quality Index and structural equation modeling, attachment anxiety was associated with higher levels of self-reported sleep difficulties for men and women, whereas attachment avoidance was not. Depressed affect was included as a control variable, and the effect of attachment anxiety remained significant. Men and women did not differ significantly in the magnitude of the effect of attachment anxiety on sleep quality. In addition, there were no cross-partner effects of attachment insecurity on sleep quality or depressed affect. Implications and future directions are discussed.

Attachment and meaning-making in perinatal bereavement.

The study examined the psychological impact of perinatal bereavement on 108 women, from a dual attachment and meaning-making perspective, both descriptively and predictively. The study hypothesized that grief acuity is a function of both attachment security (operationalized by A. Antonovsky's 1979 Sense of Coherence [SOC] scale), and the ongoing search for meaning. Controlling for time post-loss, psychological distress and intrusive thoughts; sense of coherence and search for meaning significantly predicted current grief acuity. The findings supported the conceptualization of grief as an interpretive phenomenon, elicited by the loss of a primary attachment figure, thereby shattering core life purposes, and implicating the need to reinstate meaning.
