Factor structure of the Mini-Maternal Behavior Q-Sort and associations with infant attachment: Informing precision in research and intervention.

We examined the factor structure of parental sensitivity to infants as assessed by the Mini-Maternal Behavior Q-Sort (Mini-MBQS), a 25-item short-form of the original 90-item MBQS. We aimed to: (1) identify latent factors of the Mini-MBQS; and (2) validate each factor by testing associations with infant attachment classifications. Data on parent-infant dyads (n=313; 222 mothers with 281 children, 29 fathers with 32 children) were drawn from a three-generation Australian cohort study. Exploratory Factor Analysis and Exploratory Structural Equation Modelling examined the structure of the Mini-MBQS. Two latent Mini-MBQS factors were identified, requiring 8 of 25 original items: (1) Attention and Responsiveness and (2) Contingency in Interactions. Infants with insecure attachment classifications had parents with lower sensitivity across both factors relative to infants classified secure. In particular, infants with resistant attachment classifications had parents with notably low Contingency in Interactions scores. Infants with disorganised attachment classifications had parents with the lowest relative sensitivity across both factors, and in these dyads Attention and Responsiveness scores were especially low. Results provide an empirically derived factor structure for the Mini-MBQS. Two subscales, each with significant infant attachment associations, may improve precision in clinical intervention and research translation.

Major depression as a predictor of the intergenerational transmission of attachment security: Findings from a pregnancy cohort study.

Understanding the relationship between attachment and mental health has an important role in informing management of perinatal mental disorders and for infant mental health. It has been suggested that experiences of attachment are transmitted from one generation to the next. Maternal sensitivity has been proposed as a mediator, although findings have not been as strong as hypothesised. A meta-analysis suggested that this intergenerational transmission of attachment may vary across populations with lower concordance between parent and infant attachment classifications in clinical compared to community samples. However, no previous study has examined major depression and adult attachment in pregnancy as predictors of infant-parent attachment classification at 12 months postpartum. Data were obtained on 52 first-time mothers recruited in early pregnancy, which included 22 women who met diagnostic criteria for current major depression using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders. The Adult Attachment Interview was also administered before 20 weeks of pregnancy. A history of early trauma was measured using the Childhood Trauma Questionnaire and maternal sensitivity was measured at 6 months postpartum using the observational measure of the Emotional Availability Scales. Infant-parent attachment was measured using the Strange Situation Procedure at 12 months. Overall, we found no significant association between the Adult Attachment Interview and the Strange Situation Procedure classifications. However, a combination of maternal non-autonomous attachment on the Adult Attachment Interview and major depression was a significant predictor of insecure attachment on the Strange Situation Procedure. We did not find that maternal sensitivity mediated parental and infant attachment security in this sample. While previous meta-analyses identified lower concordance in clinical samples, our findings suggest women with major depression and non-autonomous attachment have a greater concordance with insecure attachment on the Strange Situation Procedure. These findings can guide future research and suggest a focus on depression in pregnancy may be important for subsequent infant attachment.

DISORGANIZATION, FEAR AND ATTACHMENT: WORKING TOWARDSCLARIFICATION.

ABSTRACTIn 1990, M. Main and J. Solomon introduced the procedures for coding a new “disorganized” infant attachment classification for the Ainsworth Strange Situation procedure (M.D.S. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978). This classification has received a high degree of interest, both from researchers and from child welfare and clinical practitioners. Disorganized attachment has primarily been understood through the lens of E. Hesse and M. Main's concept of “fright without solution,” taken to mean that an infant experiences a conflict between a desire to approach and flee from a frightening parent when confronted by the Strange Situation. Yet, looking back, it can be observed that the way Hesse and Main's texts were formulated and read has generated confusion; there have been repeated calls in recent years for renewed theory and clarification about the relationship between disorganization and fear. Responding to these calls, this article revisits the texts that introduced the idea of fright without solution, clarifying their claims through articulating more precisely the different meanings of the term fear. This clarified account will then be applied to consideration of pathways to infant disorganized behaviors.

The parental reflective functioning questionnaire: Development and preliminary validation.

This paper reports on three studies on the development and validation of the Parental Reflective Functioning Questionnaire (PRFQ), a brief, multidimensional self-report measure that assesses parental reflective functioning or mentalizing, that is, the capacity to treat the infant as a psychological agent. Study 1 investigated the factor structure, reliability, and relationships of the PRFQ with demographic features, symptomatic distress, attachment dimensions, and emotional availability in a socially diverse sample of 299 mothers of a child aged 0–3. In Study 2, the factorial invariance of the PRFQ in mothers and fathers was investigated in a sample of 153 first-time parents, and relationships with demographic features, symptomatic distress, attachment dimensions, and parenting stress were investigated. Study 3 investigated the relationship between the PRFQ and infant attachment classification as assessed with the Strange Situation Procedure (SSP) in a sample of 136 community mothers and their infants. Exploratory and confirmatory factor analyses suggested three theoretically consistent factors assessing pre-mentalizing modes, certainty about the mental states of the infant, and interest and curiosity in the mental states of the infant. These factors were generally related in theoretically expected ways to parental attachment dimensions, emotional availability, parenting stress, and infant attachment status in the SSP. Yet, at the same time, more research on the PRFQ is needed to further establish its reliability and validity.

RANDOMIZED CONTROLLED TRIAL OF PARENT-INFANT PSYCHOTHERAPY FOR PARENTS WITH MENTAL HEALTH PROBLEMS AND YOUNG INFANTS.

There is a dearth of good-quality research investigating the outcomes of psychoanalytic parent-infant psychotherapy (PIP). This randomized controlled trial investigated the outcomes of PIP for parents with mental health problems who also were experiencing high levels of social adversity and their young infants (<12 months). Dyads were clinically referred and randomly allocated to PIP or a control condition of standard secondary and specialist primary care treatment (n = 38 in each group). Outcomes were assessed at baseline and at 6-month and 12-month follow-ups. The primary outcome was infant development. Secondary outcomes included parent-infant interaction, maternal psychopathology, maternal representations, maternal reflective functioning, and infant attachment. There were no differential effects over time between the groups on measures of infant development, parent-infant interaction, or maternal reflective functioning. Infant attachment classifications, measured only at the 12-month follow-up, did not differ between the groups. There were favorable outcomes over time for the PIP-treated dyads relative to the control group on several measures of maternal mental health, parenting stress, and parental representations of the baby and their relationship. The findings indicate potential benefits of parent-infant psychotherapy for improving mothers' psychological well-being and their representations of their baby and the parent-infant relationship.

The eye of the begetter: predicting infant attachment disorganization from women's prenatal interpretations of infant facial expressions.

Infant-caregiver attachment disorganization has been linked to many long-term negative psychosocial outcomes. While various prevention programs appear to be effective in preventing disorganized attachment, methods currently used to identify those at risk are unfortunately either overly general or impractical. The current investigation tested whether women's prenatal biases in identifying infant expressions of emotion--tendencies previously shown to relate to some of the maternal variables associated with infant attachment, including maternal traumatization, trauma symptoms, and maternal sensitivity--could predict infant attachment classification at 18 months postpartum. Logistic regression analyses revealed that together with women's adult history of high betrayal traumatization, response concordance with a normative reference sample in labeling infant expressions as negatively valenced, and the number of infant facial expressions that participants classified as "sad" and "angry" predicted subsequent infant attachment security versus disorganization. Implications for screening and prevention are discussed.

The development of negative reactivity in irritable newborns as a function of attachment

This longitudinal study builds on existing research exploring the developmental course of infants’ negative reactivity to frustration in a sample of 84 irritable infants. We investigated whether infants’ negative reactivity to frustration differed during the first year as a function of infant attachment classification. Various elements of the designs of previous studies investigating negative reactivity and attachment preclude the strong conclusion that negative reactivity develops differently as a function of attachment. Thus, we utilized the same observational assessment of infant negative reactivity, conducted without parental involvement, at 5 and 12 months. One proposition, based in attachment theory (Bowlby, 1969/1982; Cassidy, 1994), is that relative to secure infants, insecure-avoidant infants come to minimize their negative emotional reactions, whereas insecure-ambivalent infants come to maximize their negative emotional reactions. As expected, we found that at 5 months, attachment groups did not differ in reactivity, but at 12 months, insecure-avoidant infants were the least reactive, followed by secure infants, and insecure-ambivalent infants were the most reactive. Results are discussed in terms of conceptualizing the development of emotion regulation and their implications for future research.

Intergenerational relations of attachment: a research synthesis of urban/rural Mexican samples

Intergenerational relations of attachment, including adult state of mind, adult care giving quality, and infant behavior, were examined in urban and rural samples. The sample included 66 dyads of contrasting populations, 35 middle-high urban Spanish speaking families and 31 rural Indian peasant families. Measures included the Adult Attachment Interview (George, Kaplan, & Main, 1985/1996), home observations of mother–infant, and the Strange Situation attachment assessment (Ainsworth, Blehar, Waters, & Wall, 1978). Reliability among independent coders of Spanish AAI transcripts was established for the first time. Moreover, significant relations among the instruments were found, supporting the validity of the AAI to predict infant's attachment classifications and mothers sensitive care of their infants across cultures. Results further supported the cross-cultural robustness of core features of attachment theory and, to some extent, the pathway from adult state of mind through responsive care to attachment security.

Infant Attachment, Parenting Stress, and Child Emotional and Behavioral Problems at Age 3 Years

SYNOPSIS Objective. To examine the role of infant attachment classification and parenting stress for toddler emotional and behavior problems. Design. Participants were 606 infant–mother dyads who took part in a population-based cohort study in the Netherlands. Infant–mother attachment classification was assessed using the Strange Situation Procedure when the children were 14 months old. At 18 months, parenting stress was measured with the Dutch version of the Parenting Stress Index. When the children were 3 years old, both mothers and fathers completed the Child Behavior Checklist. Results. Infant attachment moderated the effect of parenting stress on child emotional and behavior problems. Parenting stress was related to more aggression and attention problem behaviors in insecurely attached children, but not in securely attached children. Moreover, higher parenting stress was associated with more withdrawal problem behaviors in insecurely attached children, in particular in insecure-resistant and in disorganized children. Conclusion. In the presence of an insecure attachment relationship, more parenting stress is related to more (internalizing) withdrawal problem behavior and to more (externalizing) aggression and attention problems. Attachment security in infancy buffers the influence of parenting stress on child emotional and behavior problems.

The missing link: Mothers’ neural response to infant cry related to infant attachment behaviors

This study addresses a gap in the attachment literature by investigating maternal neural response to cry related to infant attachment classifications and behaviors. Twenty-two primiparous mothers and their 18-month old infants completed the Strange Situation (SS) procedure to elicit attachment behaviors. During a separate functional MRI session, mothers were exposed to their own infant's cry sound, as well as an unfamiliar infant's cry and control sound. Maternal neural response to own infant cry related to both overall attachment security and specific infant behaviors. Mothers of less secure infants maintained greater activation to their cry in left parahippocampal and amygdala regions and the right posterior insula consistent with a negative schematic response bias. Mothers of infants exhibiting more avoidant or contact maintaining behaviors during the SS showed diminished response across left prefrontal, parietal, and cerebellar areas involved in attentional processing and cognitive control. Mothers of infants exhibiting more disorganized behavior showed reduced response in bilateral temporal and subcallosal areas relevant to social cognition and emotion regulation. No differences by attachment classification were found. Implications for attachment transmission models are discussed.

Genetic and Caregiving-Based Contributions to Infant Attachment

In the longitudinal study reported here, we examined genetic and caregiving-based contributions to individual differences in infant attachment classifications. For 154 mother-infant pairs, we rated mothers’ responsiveness to their 6-month-old infants during naturalistic interactions and classified infants’ attachment organization at 12 and 18 months using the Strange Situation procedure. These infants were later genotyped with respect to the serotonin-transporter-linked polymorphic region (5-HTTLPR). Maternal responsiveness uniquely predicted infants’ attachment security. Infants’ 5-HTTLPR variation uniquely predicted their subtype of attachment security at 12 months and their subtype of attachment insecurity at 12 and 18 months. The short allele for 5-HTTLPR was associated with attachment classifications characterized by higher emotional distress. These findings suggest that 5-HTTLPR variation contributes to infants’ emotional reactivity and that the degree to which caregivers are responsive influences how effectively infants use their caregivers for emotion regulation. Theoretical implications for the study of genetic and caregiving influences are discussed.

The Baby Out of the Bathwater: Microseconds, Psychic Structure, and Psychotherapy

Infant development research has proposed links between early development and adult personality and psychopathology. Although clinicians have long taken these for granted, these research approaches raise a number of methodological and clinical issues worth exploring. Analysts have relied on varied formulations of “psychic structure,” but these are sometimes elusive and have not lent themselves to the precision, specificity, and validation that some analysts and many developmentalists prefer. New models have emerged over the last decades, including conceptions of internal working models of attachment, implicit relational knowing, and the like. Attachment research has shown strong correlations between infant attachment classification and adult personality. Recent research such as that of Beebe, Jaffe, and their colleagues has extended the correlations between early mother–infant interaction patterns and adulthood. All of this supports clinicians' interest in attention to the details of analyst–patient interaction, emotion regulation, inersubjective meaning-making, and other markers that can be observed in both infancy and adult analysis.

The development of father–child attachment: associations between adult attachment representations, recollections of childhood experiences and caregiving

The association between fathers' adult attachment representations and their recollections of childhood experiences with their caregiving quality with their eight-month-old infants and with father–infant attachment classification was examined in a longitudinal study of 117 fathers and their infants. Sensitive caregiving was related to secure-autonomous classification in the Adult Attachment Interview (AAI), hostile caregiving was related to fathers' dismissing and unresolved attachment, and emotional disengagement and role-reversed caregiving were both related to fathers' unresolved attachment. Childhood experiences of parental pressure to achieve were related to fathers' hostile and role-reversed caregiving and low sensitivity, independent of AAI classification. However, fathers' childhood experiences of maternal neglect were related to high-quality caregiving. It was also found that fathers' secure-autonomous AAI classification was related to secure father–child attachment in the Strange Situation Paradigm, and this relation was mediated by sensitive caregiving.

Attachment and selective attention: Disorganization and emotional Stroop reaction time

Although central to attachment theory, internal working models remain a useful heuristic in need of concretization. We compared the selective attention of organized and disorganized mothers using the emotional Stroop task. Both disorganized attachment and emotional Stroop response involve the coordination of strongly conflicting motivations under conditions of emotional arousal. Furthermore, much is known about the cognitive and neuromodulatory correlates of the Stroop that may inform attempts to substantiate the internal working model construct. We assessed 47 community mothers with the Adult Attachment Interview and the Working Model of the Child Interview in the third trimester of pregnancy. At 6 and 12 months postpartum, we assessed mothers with emotional Stroop tasks involving neutral, attachment, and emotion conditions. At 12 months, we observed their infants in the Strange Situation. Results showed that: disorganized attachment is related to relative Stroop reaction time, that is, unlike organized mothers, disorganized mothers respond to negative attachment/emotion stimuli more slowly than to neutral stimuli; relative speed of response is positively related to number of times the dyad was classified disorganized, and change in relative Stroop response time from 6 to 12 months is related to the match-mismatch status of mother and infant attachment classifications. We discuss implications in terms of automatic and controlled processing and, more specifically, cognitive threat tags, parallel distributed processing, and neuromodulation through norepinephrine and dopamine.

Differentiating among insecure mother - infant attachment classifications: A focus on child - friend interaction and exploration during solitary play at 36 months

Utilizing data from the NICHD Study of Early Child Care, the primary objective of the current report was to examine how avoidant and resistant mother-infant attachment classifications at 15 months were differentially associated with children's interaction with a same-sex friend and exploration during solitary play at 36 months. The added contributions of attachment security at 36 months and maternal sensitivity from 6 to 36 months to the prediction of child outcomes were also explored. As hypothesized, an avoidant attachment history was related to more instrumental aggression during child-friend interaction, whereas a resistant attachment history was associated with less self-assertion/control among friends and less attention and pretend play during exploration. Maternal sensitivity and concurrent attachment security also made unique contributions to the prediction of child outcomes at 36 months, although associations with 15-month attachment remained significant when these subsequent measures of the mother-child relationship were considered. Few differences emerged for the disorganized mother-infant attachment category in this relatively low-risk sample. Results underscore the need to differentiate between avoidant and resistant attachment groups and illustrate how early attachment history and subsequent indices of the mother-child relationship contribute to children's functioning.

Earned-secure attachment status in retrospect and prospect.

Past research with the Berkeley Adult Attachment Interview demonstrates that retrospectively defined earned-secures (who coherently describe negative childhood experiences) parent as effectively as do continuous-secures (who coherently describe positive childhood experiences), but manifest liabilities in the form of depressive symptomatology. This article presents data from a 23-year longitudinal study that replicate and extend prior research, testing a key premise that earned-secures so defined actually have a history of insecure attachments that change over time and/or endure consistently harsh or ineffective parenting in their youth. Discrepant with assumptions, retrospective earned-secures were not more likely than continuous-secures to have been anxiously attached in infancy and were observed in childhood and adolescence to have encountered among the most supportive and structured maternal parenting in a high-risk sample. Prospectively defined earned-secures (operationalized using participants' infant attachment classifications) did indeed go on to have success in their close relationships, many without reporting relatively high levels of internalizing distress in adulthood.

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.

Failure-to-thrive is associated with disorganized infant-mother attachment and unresolved maternal attachment

This study provides further evidence for the co-occurrence of atypical patterns of attachment and failure-to-thrive (FTT). Eighty-three children with FTT and 130 normally growing comparison children were seen in Ainsworth's Strange Situation at ages 11 to 32 months. These subjects were highly diverse with respect to social, economic, and ethnic characteristics. Children with FTT were significantly less likely to show secure and more likely to show anxious, disorganized attachments than normally growing comparisons: only 34% of FTTs were secure, while 46% showed disorganized attachments. In contrast, 66% of comparisons were secure and 16% were disorganized. In addition, a subsample of 59 mothers (23 FTT and 36 comparison) were interviewed with the Adult Attachment Interview (AAI). Mothers of FTTs were more than twice as likely as comparisons (65% versus 22%) to use discourse indicating unresolved loss or trauma. Similarly, mothers of FTTs were less likely to show autonomous (secure) discourse than mothers of well-nourished children (13% versus 58%). There were no differences in infant or adult attachment classifications between organic and nonorganic FTT groups, further discrediting this as a psychologically meaningful distinction. These results support the notion that disturbed patterns of attachment are common in FTT, regardless of the etiology of growth failure. The findings suggest that evaluations and treatments of FTT should address psychological, as well as medical problems in these families. © 2000 Michigan Association for Infant Mental Health.

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.

Disorganized Infant Attachment Classification and Maternal Psychosocial Problems as Predictors of Hostile-Aggressive Behavior in the Preschool Classroom

This study of 62 low-income families examined the relation between maternal and infant measures assessed at 18 months infant age and child behavior problems at age 5 as rated by preschool teachers. The infancy assessments included measures of mother-infant interaction, maternal psychosocial problems, infant cognitive development, and infant attachment security, including the disorganized/disoriented classification. The strongest single predictor of deviant levels of hostile behavior toward peers in the classroom was earlier disorganized/disoriented attachment status, with 71% of hostile preschoolers classified as disorganized in their attachment relationships in infancy. Maternal psychosocial problems independently predicted hostile aggression in preschool and combined additively with infant attachment security in prediction. Results are discussed in relation to the asymmetry of forward and backward prediction that characterized the findings and in relation to the potential significance of disorganized attachment behavior as a precursor to later maladaptation.
