Perceptions of infant boys' behavior and mental health: Relation to infant attachment

Two studies were conducted to determine the impact of infants' attachment classifications and behaviors on naive adults' impressions of their behavior and mental health. In Study 1, three groups of 44 adults viewed a videotape of episode 8 of the Strange Situation for either an avoidant, a resistant, or a secure male infant. After viewing the videotape, they made judgments about aspects of the infant's mental health. Adults viewed the resistant baby as less socially competent and more negative in affect than the other two babies and the secure baby as the least independent of the three babies. Parents rated babies as more intelligent than did nonparents. In Study 2, 15 parents were matched on race and gender with 15 nonparents. All adults viewed a videotape of the reunions of two secure, two avoidant, and two resistant male infants. Avoidant babies were viewed as more socially competent and independent than secure babies and the C2 baby was viewed as the least intelligent, least independent, least socially competent, and most affectively negative of the infants. Results are interpreted as underscoring the need to educate parents and paraprofessionals about the importance of infant distress and physical contact with parents.     

Attachment patterns and emotion regulation strategies in the second year

With the aim of studying the relationship between methods of emotion regulation and quality of attachment we examined 39 infants with different patterns of attachment, of whom 20 were classified as secure (B), 12 as avoidant (A) and 7 as resistant (C), assessing the regulatory strategies adopted by them during the Strange Situation at 13 months. Secure infants used strategies of positive social engagement more than insecure avoidant infants, while resistant infants displayed greater negative social engagement and less object orientation than the other two groups. Avoidant infants adopted positive and negative hetero-regulatory strategies less than the other groups, also differing from resistant infants in their greater use of object regulatory strategies. There were no significant differences as regards self-comforting regulation. Thus, the findings showed how the most significant differences to emerge between the groups concerned hetero-regulatory strategies, developed by the infant in interaction with attachment figures, and regulatory strategies oriented towards objects. Further analysis showed how the use by part of each attachment group of the emotion regulation strategies varies, differentiating the episodes of the SSP according to their level of stress.     

Nonmaternal care hours and temperament predict infants’ proximity-seeking behavior and attachment subgroups

Using the NICHD Early Childcare dataset (N = 1281), this study examined whether infant temperament and the amount of time infants spend in nonmaternal care independently predict (1) the likelihood that they seek comfort from their mother when needed and (2) placement in a particular subgroup of infant-mother attachment patterns. Mothers reported the number of hours their infant spent in nonmaternal care each month and their infant's difficulty adapting to novel stimuli at 6 months. The degree to which 15-month-old infants seek comfort from their mother during reunion episodes in the Strange Situation was observed using two behavioral scales (“proximity seeking” and “contact maintaining”). Their average score forms the outcome variable of “proximity-seeking behavior.” The other outcome variables were the subgroups of infant-mother attachment patterns: two subgroups for insecure babies (resistant and avoidant) and four subgroups for secure babies (B1, B2, B3, and B4). Easy adaptability to novel stimuli and long hours of nonmaternal care independently predicted a low level of proximity-seeking behavior. These predictors also increased the likelihood of an insecure infant being classified as avoidant (vs. resistant). A secure infant with these same predictors was most likely to be classified as B1, followed by B2, and then B3, with B4 being the least likely classification. Although previous studies using the NICHD dataset found that hours of nonmaternal care had no main effect on infants’ attachment security (vs. insecurity), this study demonstrates that hours of nonmaternal care predict the subcategories of infant-mother attachment.     

The relation between infants' self/mother knowledge and three attachment categories

The relation between attachment and knowledge of self and mother was assessed in 1-to 2-year-old infants. Infant behavior in the Strange Situation was classified according to three attachment categories: secure, insecure-avoidant, and insecure-resistant. Infants' featural knowledge was measured by featural recognition, name, possession, and gender. Infants who were securely or resistantly attached had significantly more complex knowledge of mother than self, whereas avoidantly attached infants did not differ in the complexity of knowledge of self and mother. Securely attached infants had more complex self-knowledge than both categories of insecurely attached infants. In contrast, avoidantly attached infants had less complex knowledge of mother than did securely or resistantly attached infants. These data are discussed in the context of how infants' strategies of coping with stress are related to the acquisition of self- and mother-knowledge.     

Attachment security differs by later autism spectrum disorder: A prospective study

Although difficulties with social relationships are key to autism spectrum disorder (ASD), no previous study has examined infant attachment security prior to ASD diagnosis. We prospectively assessed attachment security at 15 months in high‐risk infants with later ASD (high‐risk/ASD, n = 16), high‐risk infants without later ASD (high‐risk/no‐ASD, n = 40), and low‐risk infants without later ASD (low‐risk/no‐ASD, n = 39) using the Strange Situation Procedure. High‐risk/ASD infants were disproportionately more likely to be classified as insecure (versus secure) and more likely to be classified as insecure‐resistant (versus secure or avoidant) than high‐risk/no‐ASD and low‐risk/no‐ASD infants. High‐risk infants with insecure‐resistant attachments were over nine times more likely to receive an ASD diagnosis than high‐risk infants with secure attachments. Insecure‐resistant attachment in high‐risk infants suggests a propensity toward negative affect with the parent in conditions of stress. Insecure‐resistant attachment may prove useful as a potential early index of propensity toward ASD diagnosis in high‐risk siblings, while insecure‐resistant attachment in the context of emergent autism may contribute to difficulties experienced by children with ASD and their families.     

Maternal unresolved attachment status impedes the effectiveness of interventions with adolescent mothers

Children of adolescent mothers are at risk for a variety of developmental difficulties. In the present study, the effectiveness of a brief intervention program designed to support adolescent mothers' sensitivity to their infants' attachment signals was evaluated. Participants were adolescent mothers and their infants who were observed at 6, 12, and 24 months of age. The intervention conducted by clinically trained home visitors consisted of eight home visits between 6 and 12 months in which mothers were provided feedback during the replay of videotaped play interactions. At 12 months, 57% of the mother–infant dyads in the intervention group and 38% of the comparison group dyads were classified as secure in the Strange Situation. Seventy‐six percent of the mothers in the intervention group maintained sensitivity from 6 to 24 months compared with 54% of the comparison mothers. Further analyses indicated that the intervention was effective primarily for mothers who were not classified as Unresolved on the Adult Attachment Interview.     

Maternal correlates of stability and change in infant-mother attachment

The relations between maternal control style, sensitivity, and childrearing attitudes on one hand and the stability of the infant-mother attachment relationship on the other were examined in a sample of 38 mother-infant dyads. The mother-child pairs were observed during a structured play session and in Ainsworth's Strange Situation when the infants were 12 and 20 months old, a developmental period characterized by increased autonomous functioning. Our results suggested that infants whose mothers had nonpunitive childrearing attitudes, were sensitive, and supportive of their infants' striving toward autonomy remained, or became, secure in their attachment relationship over their second year of life. Mothers who were more punitive, more controlling, and less sensitive had infants who either remained or became insecurely attached across this developmental period. While previous research has linked attachment stability to socioeconomic factors, the present investigation points to the importance of more subtle interactive variables to the understanding of the attachment relationship.     

Relations between strange situation behavior and stranger sociability among infants on Israeli Kibbutzim

Eighty-six kibbutz-reared infants were observed in the Strange Situation with their mothers, fathers, and metaplot on three separate occasions between 11 and 14 months of age. Prior to each Strange Situation, sociability with male and female strangers was assessed. A-group and B-group infants were significantly more sociable than B₄- and C-group infants. Relations with stranger sociability were strongest for Strange Situation classifications of infant-parent attachement. It was also necessary to abbreviate many of the Strange Situation sessions: usually the infants whose sessions were abbreviated obtained very low sociability scores and were classified in the B₄- and C-groups. Findings confirmed previous relations between Strange Situation classifications and stranger sociability, but cast doubt on the appropriateness of considering the B₄ subgroup as part of the “secure” B group. They also suggest that variations in stranger sociability (or its extreme negative pole, stranger distress) may in some cases determine variations in Strange Situation classifications, rather than the reverse.     

Observing mother-child relationships across generations: boundary patterns,attachment, and the transmission of caregiving

Grounded in both attachment and family systems theories, this study is one of the first to examine how relationship patterns observed in mothers' current relationships with their own mothers are recreated in their relationships with their infants. Mostly white, middle-class families (N = 55), including maternal grandmothers, mothers, and infants, were observed when infants were 6, 9, and 18 months old. At 6 months, mothers and grandmothers completed self-report assessments and worked together on discussion tasks. These interactions were coded using the Boundary Assessment Coding System, developed for the present study, which assessed three relational patterns: disengagement, balance, and entanglement. At 9 months, mothers were rated on sensitivity and intrusiveness while playing with and feeding their infants; and, at 18 months, infant-mother attachment was assessed using the Strange Situation. Multiple regression analyses revealed, as predicted, that mothers who remembered being accepted by their mothers as children and who were in highly balanced relationships with their own mothers currently were more sensitive and less intrusive with their 9-month-old infants. Further, discriminant function analyses indicated that memories of acceptance, high levels of balance, and low levels of disengagement differentiated secure from insecure attachment, whereas memories of overprotection and high levels of entanglement distinguished resistant from secure and avoidant attachment. Discussion focuses on the theoretical hypothesis that mothers internalize relationship strategies experienced with their own caregivers and recreate these patterns with their infants.     

The emotional quality of childcare centers in Israel: The Haifa study of early childcare

Data from an Israeli project shows higher proportion of insecurely attached infants in center care as compared with noncenter care (Sagi, Koren‐Karie, Gini, Ziv, & Joels, 2002). The present study was designed to assess structural and emotional aspects characterizing infants' experiences in center care, aiming to explain, in part, the high incidence of attachment insecurity among center‐care infants. In the present study, we focus on 151 center‐care infants who were observed in the Ainsworth Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978) with their mothers. Sixty‐one percent of them were coded as securely attached to their mothers while 39% were coded as insecurely attached. In addition, 56 directors and 120 caregivers in 56 centers were videotaped throughout a full‐day observation. The Assessment Profile of Early Childhood Program (Abbott‐Shim & Sibley, 1987) was also employed. Results indicated that the centers in Israel are of low standards: Large group size, high caregiver–infants ratio, inadequate professional training, and minimal attention to individual emotional needs. No associations were found between infants' attachment and various aspects of the settings. The low quality of the Israeli settings may explain the higher rate of attachment insecurity in center‐care infants. ©2005 Michigan Association for Infant Mental Health.     

Are infant attachment patterns continuously or categorically distributed? A taxometric analysis of strange situation behavior

Contemporary attachment research is based on the assumption that at least three types of infant attachment patterns exist: secure, avoidant, and resistant. It is not known, however, whether individual differences in attachment organization are more consistent with a continuous or a categorical model. The authors addressed this issue by applying P. E. Meehl's (1973, 1992) taxometric techniques for distinguishing latent types (i.e., classes, natural kinds) from latent continua (i.e., dimensions) to Strange Situation data on 1,139 fifteen-month-old children from the NICHD Study of Early Child Care. The results indicate that variation in attachment patterns is largely continuous, not categorical. The discussion focuses on the implications of dimensional models of individual differences for attachment theory and research.     

The Effect of Research with Teenage Mothers on the Development of Their Infants1

Mother-infant interaction of 14 teenage mothers and 12 women 20 years or older was observed and recorded in the laboratory or the home when the infants were 16, 20, 24, and 52 weeks of age. In order to assess the possible effect of the research intervention on the maternal behavior and on the infants' development, a control group of teenage mothers and their infants was seen only at the end of the study when the infant was 52 weeks old. At 12 months the Home Observation Measure of the Environment Inventory (HOME) was administered and infants were assessed with the Bayley Scales of Infant Development (motor and mental scales) and the Ainsworth Strange Situation procedure. On all measures the observation groups scored significantly higher than the control group. The significant aspects of the research intervention are discussed.     

Attachment,temperament, and social referencing: Interrelationships among three domains of infant affective behavior

The relations among attachment, temperament, and social referencing—three constructs tapping individual differences in affectivity—were investigated in a sample of 48 12-month olds. Social referencing behavior was observed in three laboratory situations, attachment measures were rated during the Ainsworth Strange Situation, and temperament was assessed by Rothbart's (1981) Infant Behavior Questionnaire (IBQ). A broad temperament factor predicted some Strange Situation behaviors and the information-seeking component of social referencing, but few of the expected relationships between attachment and social referencing were confirmed.     

The influence of Japanese mothers' styles of emotional expression on thirteen-month-old infants' reactions to a stranger

The present study investigated the hypothesized influence of mothers' styles of emotional expression on infants' responses to the stranger in Episode 3, the Ainsworth Strange Situation. One hundred and thirty-five mothers volunteered for this experiment with their 13-month-olds. The mothers' answers on an expression style questionnaire (EESQ) were factor analysed. According to their mothers' factor scores, infants were divided into four groups, those having (a) expressive type mothers (N = 40), (b) suppressive type mothers (N = 39), (c) positive expressive type mothers (N = 31), and (d) negative expressive type mothers (N = 25). The infants' behaviours were analysed in 5-sec intervals. The infants having expressive type mothers showed a strong interest in the stranger and interacted with her willingly. The infants having suppressive type mothers exhibited less smiling and much freezing behaviour. The infants having positive expressive type mothers reacted with more smiling, much bodily contact behaviour with the mother and less crying. The infants having negative expressive type mothers showed more often crying and frequent head orientation towards the stranger.     

Applicability and attachment findings of the Strange Situation Paradigm in infants with visual impairment

Attachment studies with diverse populations enrich the understanding of infants’ socioemotional development by documenting both universal and idiosyncratic aspects of attachment. Given the effects of attachment in children's socioemotional outcomes, such studies are necessary to investigate the impact of children's sensory impairments on attachment development. Yet, very little attachment research has focused on infants with visual impairment (VI infants), a population in which infant–caregiver emotional exchanges through visual means are reduced/absent. We investigated the applicability of the Strange Situation Paradigm (SSP), with added instructions to compensate for degraded visual input, in 20 VI infants (with no additional disabilities and who were receiving developmental counseling). In all but 1 of the SSPs coded, VI infants displayed observable attachment behavior that was classifiable. Nineteen VI infants showed attachment by 12 months of age. Across the ages tested (fractional age range = 0.9–2.33 months), most VI infants’ attachment patterns were classified as secure and organized.     

Predicting infant attachment classification from multiple, contemporaneous measures of maternal care

This investigation was designed to test whether stylistic differences in maternal caregiving were associated with both secure and insecure mother-infant attachment classifications in a low-income sample. Multiple measures of maternal interactive behavior and care were collected from a sample of 95 urban, low-income mothers and their 12-month-old infants. Contemporaneous relations to attachment were found only at the broad level of composite scores of caregiving. Scores derived from different measures were aggregated to create composites reflecting three caregiver styles—sensitive, controlling, and unresponsive. Mothers of infants with secure attachment classifications showed greater sensitivity and less controlling behavior than mothers of infants with resistant and avoidant attachments, respectively. Mothers of infants with resistant attachments appeared less responsive to their infants' signals than those of infants with avoidant attachments. Group differences were significant, but modest. These results contribute to the growing body of studies relating parental care with infant attachment patterns and indirectly support the more recent conceptual work on intergenerational transmission of attachment. They also raise methodological issues that need to be considered in future work on caregiving and infant-mother attachment.     

Attachment and temperament in early childhood; implications for later behavior problems

In the context of a French validation study, the Child Behavior Checklist (CBCL) was administered to more than 3000 French speaking mothers of 5‐year‐old children. Scores were factor‐analyzed. Principal components analysis revealed four dimensions: externalizing and internalizing behavior problems, immaturity and somatoform disorders. Another sample of 40 mothers participated in a longitudinal study, filling in the CBCL when their children were 5 years old. These children had been observed previously in the Strange Situation (SSP) at 21 months. Several dichotomous variables derived from the SSP (e.g. secure versus insecure, proximal versus distal interaction with the mother, avoidant behavior) have been used as predictors of the four dimensions extracted from the CBCL. Hierarchical regressions showed that proximal behaviors with the mother, which reflect temperamental characteristics independently of the quality of attachment, predicted internalizing problems, whereas avoidance of the mother, or insecure–avoidant attachment, predicted internalizing as well as externalizing problems at 5 years of age. These results show that attachment and temperament, as assessed by the SSP, may each have specific implications for later behavior problems. Copyright © 2000 John Wiley & Sons, Ltd.     

Strange situation behavior of infants with adolescent mothers

Forty 6-month-old infants and their adolescent mothers were observed interacting at home and in Ainsworth's Strange Situation procedure when the infants were 14 months old. There were significantly more A-group infants (45%) and fewer C-group infants (3%) at 14 months in this sample of adolescent mothers than in other samples of adult mothers. Furthermore, A-group attachments were more common when levels of dyadic engagement at 6 months had been lower, and future A-group infants were less vocal at 6 months than were future B-group infants. At 6 months, mothers of future B-group infants provided more care than did mothers of future A-group infants. These findings provide some support for claims that adolescent mothers provide parenting of lower quality than adult mothers and that quality of early interactions may predict subsequent infant behavior in the Strange Situation.     

AQS security scores: What do they represent? A study in construct validation

In a sample of 129 Dutch 15‐month‐old infants, attachment security was assessed both with the Attachment Q‐Set (AQS; Waters, 1995) and with a short version of Ainsworth, Blehar, Waters, and Wall's (1978) Strange Situation (SSS). Infants classified as secure using the SSS had significantly higher AQS scores than insecure and disorganized infants in particular. At the AQS item level, disorganized infants were described as significantly more noncompliant, fussy, and angry relative to secure infants. When security as assessed using the SSS was controlled, the observed quality of parental interactive behavior, parental ego‐resilience, high levels of infant task orientation and pleasure, and low levels of infant anger proneness were found to explain significant and unique portions of the variance in the AQS security scores. The apparently unfavorable set of characteristics associated with low AQS security scores suggests such scores to predict later developmental problems. ©2004 Michigan Association for Infant Mental Health.
