Predicting secure infant attachment Daniel Messinger, Ph.D. Review In the presence of a consistent caregiver almost all infants form an attachment We’ve reviewed the classification of infant security of attachment in the strange situation. But what predicts a secure versus an insecure attachment? Messinger 2 Predicting attachment security What different roles might infant temperament have in predicting security of attachment? What is the experimental evidence that caregiver sensitivity factors predicts secure attachment? What is the meta-analytic evidence that caregiver sensitivity factors predicts secure attachment? Messinger 3 Big picture What produces secure attachment? Infant – Temperament Caregiver – Sensitivity Social situation – divorce, daycare, social support – May affect infant directly – Situation - infant Or affect infant indirectly: Situation – caregiver sensitivity - infant Messinger 4 Infant Attachment and Maternal Depression Mixed evidence – – – Some studies show effects, others do not Chronicity of depression may be key More consistent influence on day-to-day interaction Sample study – Attachment insecurity significantly associated with maternal depression among infants and preschoolers. – Disorganized attachment especially common among mothers with more chronic depression. • Teti, Gelfand, Messinger, & Isabella (1995). Maternal depression and the quality of early attachment: An examination of infants, preschoolers, and their mothers. Developmental Psychology, 31(3), 364-376 Messinger 8 Orthodox View Caregiver (Mother) Driven System – – – Sensitive caregiving yields secure attachment Caregiver can adapt to any child temperament Who’s has responsibility according to this systerm? Messinger 9 What is sensitivity? Responsive Understands and accepts the child’s individual proclivities Orchestrates harmonious interactions – “especially involving the soothing of distress” In a variety of situations – On a relatively consistent basis • Belsky, 1999, p. 249 Messinger 10 Just the right amount Unresponsive caregiving Avoidant attachment – Sensitive caregiving Secure attachment – Attachment behaviors responded to appropriately Inconsistent/intrusive caregiving Resistant attachment – Attachment behaviors are suppressed (extinguished) Attachment behaviors only work when they are strong and insistent (intermittent reinforcement) But little empirical evidence distinguishing parent behaviors distinguishing A & C Messinger 11 Mother or child? Meta-analysis of 34 clinical studies indicates that maternal problems such as mental illness lead to more deviating attachment classification distributions than child problems such as deafness. In clinical samples, the mother appears to play a more important role than the child in shaping the quality of the infant-mother attachment relationship • Van IJzendoorn, Goldberg, Kroonenberg, & Frenkel (1992). Messinger 12 Temperament & Care giving Child characteristics and care giving – – Continuously and reciprocally impact each other in day-to-day interaction and development. Little information on the process through which this occurs Seifer et al. But lots of information on strength of respective caregiver and child influences Messinger 13 Effects of child care on infantmother attachment security Significant effects of maternal sensitivity and responsiveness. No significant effects of child-care experience (amount, age entry, or type of care) on attachment security or avoidance. – – Interaction: more insecure when low maternal sensitivity/responsiveness combined with poor quality child care, more than minimal child care, or more than one care arrangement 1,153 infants – NICHD study of early child care. Child Development. 1997. 68(5) 860-879 Messinger 14 Same at 36 months No child-care factors (quantity, quality, or type) predicted attachment security Maternal sensitivity was strongest predictor of preschool attachment classification. Interaction: Low maternal sensitivity & more hours per week in care somewhat increased the risk of insecure (C). – Significant but modest stability of attachment classifications from 15 to 36 months especially for children with A and C classifications. Messinger 15 Where does security lie? In the infant or in the caregiver-infant dyad? A meta-analysis of infant-father attachment shows weak but significant association between security of attachment to mother and father. – Does this suggest a role for temperament? Messinger 16 Two Temperamental Pathways Indirect effect – Temperament Caregiver-Infant interaction Attachment security Direct effect (Not empirically supported) – – – Temperament Strange Situation Behavior “Attachment Security” Less prone to distress “Avoidant” More prone to distress “Resistant” Messinger 17 Messinger 18 Genetic and Caregiving-Based Contributions to Infant Attachment Two contrasting explanations of differences in attachment: – – Quality of infant-caregiver relationship Reflection of infants’ temperament Emphasis on emotional reactivity vs. emotion regulation Proposed reconciliation: distress reactivity during SSP shaped by predispositions for negative emotionality Gangi Distress and the Strange Situation Belsky and Rovine’s 1987 Grouping Low Distress: Securely Attached B1 Securely Attached B2 Insecure Avoidant High Distress: Securely Attached B3 Securely Attached B4 Insecure Resistant Billingsley 20 Empirical Findings Initial results positive Subsequent results mixed Inconsistency attributed to methodological variation & complexity of infant emotion Proposed solution: molecular genetics Billingsley 22 5-HTTLPR Serotonin transporter linked polymorphic region Short (S) vs. Long (L) alleles S allele associated with: diminished transcription reduced serotonin uptake heightened amygdala activity Billingsley 23 Genetic and Caregiving-Based Contributions to Infant Attachment 155 infants and mothers Measures of: – – – – – Maternal responsiveness at 6 months Attachment at 12 and 18 months Emotional distress in SSP (Belsky’s grouping) 5-HTTLPR variation Raby et al., 2012 Gangi Genetic and Caregiving-Based Contributions to Infant Attachment Maternal responsiveness predicted attachment 5-HTTLPR predicted distress during SSP – No prediction to attachment security, but subtypes Genetic variation and caregiving context make unique contributions to differences in attachment behavior – – Caregiving secure vs. insecure 5-HTTLPR how this is manifested Gangi Disorganized attachment predicted by parent behavior Strongly related to parental maltreatment, & moderately related to sensitivity Unrelated to difficult infant temperament 2 studies have linked frightening parental behavior to disorganized attachment Though – not significantly related to depression van IJzendoorn, M.

Messinger 27 More evidence for care-giving effects Experimental Observational – Meta-analysis of quasi-experiments Messinger 28 Experiment 1: Sensitivity training 100 irritable, low-SES Dutch infants 50 mothers in experimental group – receive 3 home visits to foster “contingent, consistent, and appropriate responses to + and infant signals” 50 control mothers are observed only Messinger 29 Results Experimental infants 36/50 (72%) secure Control infants: 16/50 (32%) secure Sensitivity training for mother decreases rates of insecurity among irritable infants Meta-analysis of intervention studies showed a moderately large effect size, d = .48 – Van den Boom Messinger 30 Experiment 2: Replicate the Snuggly Effect! 49 low-socioeconomic status (SES) mothers of newborn infants Given soft baby carriers (more physical contact) or infant seats (less contact). More experimental (83%) than control infants (38%) were securely attached at 13 mo. – 3.5 mo, mothers in the experimental group were more contingently responsive than control mothers to their infants' vocalizations. Low cost experimentally-validated intervention? • Anisfeld, Casper, Nozyce, & Cunningham (1990). Does infant carrying promote attachment? An experimental study of the effects of increased physical contact on the development of attachment. Child Development, 61(5), 1617-1627. Messinger 31 Conclusions Sensitivity is important – Temperament may also be a factor Does sensitive interaction make a difference in naturalistic settings Many studies have been done – using many measures of interaction Meta-analysis can help sort them out Messinger 32 Sensitivity Studies Only Perceive signals accurately and respond promptly and appropriately – 22% (r = .22), 7,223 infants in 123 comparisons Original Ainsworth subscale – – 24% (r = .24), 837 infants in subset of 16 studies Socioeconomic class is a moderator Middle (r = .27); lower (r = .15) Messinger 41 Conclusions Sensitivity and quality of interaction are important and consistent (but not exclusive) predictors of attachment security. Sensitivity important but not only factor – Orthodox hypothesis supported weakly Messinger 44 Can infant attention studies shed light on caregiving (or temperamental) roots of attachment security?

Chen 46 Messinger 47 Messinger 48 7 month old infants grouped by attachment security Messinger 49 7 month fear bias score and disorganization Messinger 50 However, interactions with genes reported by Barry et al. 2008 Messinger 52 Autism challenges attachment theory 55 toddlers with autism spectrum disorder (ASD), mental retardation, language delay, and typical development. – Parents of children with ASD =y sensitive as other parents But children show more disorganization, less involvement. More sensitive parents had more secure children, – diagnosed at 4 years. Two years before, attachment, sensitivity assessed but only in group without ASD. Less severe autistic symptoms in the social domain predicted more attachment security.. • van Ijzendoorn, M. H., Rutgers, A. H., Bakermans-Kranenburg, M. J., van Daalen, E., Dietz, C., Buitelaar, J. K., et al. (2007). Parental sensitivity and attachment in children with autism spectrum disorder: Comparison with children with mental retardation, with language delays, and with typical development. Child Development, 78, 597-608. Messinger 53 Autism challenges attachment theory Subtle attachment differences: More distance security 27% 73% 42% 58% Haltigan et al., 2010 FFSF Mid-range models In pilot analyses based on continuous ratings of affect, for example, mid-range levels of mother responsiveness (infant-to-mother interactive influence) were associated with 15-month attachment security, the highest levels were associated with resistance, and the lowest levels with avoidance and disorganized attachment classifications, F(3,23) = 3.55, p = .03, estimated ω2 = .24. Builds on Beebe et al. But where is the evidence that early measured interaction predicts attachment? Messinger 57 Sensitivity Sensitive caregiving promotes attachment. – But effects are not universally found Seifer et al., 1996 Sensitive caregiving is underspecified What does sensitivity look like crossculturally and in different subcultures? Messinger 58 Attachment & social play What does sensitivity look like in different caregiving domains such as playmate and attachment figure? Attachment theory is not clear as to whether the concepts are distinguishable and what type of association is to be expected. Messinger 59 Cross-cultural evidence Among dyads living in subsistence societies secure attachment exists in relationships in which social play between caregiver and child was not observed and was seen as frivolous. Gusii, Ganda, etc. Secure attachment without play – The anthropological veto Messinger 61 Meta-analytic results De Wolff and van Ijzendoorn also found that Ainsworth-based measures of sensitivity were stronger predictors of attachment security in middle-class r = .27) than lower-class dyads (r = .15). Messinger 64 Variability Characterizes the association between security of attachment and quality of social play cross-culturally Messinger 65 Attachment as organizer Attachment is pre-eminent "affective bond" that organizes interaction between infant and caregiver (organizational construct perspective) – If attachment is secure, Positive play should be possible or play should be positive Messinger 66 ‘Limited relations between attachment security and quality of social interaction.’ Messinger 67 The Paradox of Sensitivity Strongly predictive of many outcomes But somewhat subjective in content – A joystick resolution? Messinger 69 In a teaching situation, student non-experts rate teaching even if you ask them to rate supportiveness Sensitive structuring (“the degree to which the parent is involved in providing appropriate structure and teaching for the child”), – ICC = .75, and concordance with expert ratings, r = .71 But emotional supportiveness (“the degree to which the parent is warm, positive, responsive and supportive to her child, while also respecting the child’s independence”). – ICC = .47, r = .36, ns. In fact, non-expert emotional supportiveness ratings exhibited high associations with the structuring ratings of experts, – r =.78, p < .001, and non-experts, r =.70, p < .01. Messinger 70 Sensitivity in the SS Lower levels of maternal sensitivity (Behrens, Parker, & Haltigan, 2011; Leerkes, Parade, & Gudmundson, 2011; Smith & Pederson, 1988) and more frequent maternal displays of atypical behaviors (e.g., lower responsivity, inappropriate responses to child affect, disrupted communication; Goldberg, Benoit, Blokland, & Madigan, 2003; Goldberg, MacKay-Soroka, & Rochester, 1994; Lyons-Ruth, Bronfman, & Parsons, 1999) have been documented most often amongst insecurely attached children and children with disorganized attachment when maternal behavior and child attachment were assessed concurrently in the SSP Messinger 71 References Interactional and contextual determinants of attachment security (Belsky, 1999) The Nature of the Child’s Ties (Cassidy, 1999) Sensitivity and attachment: A meta-analysis on parental antecedents of infant attachment (De Wolff & van IJzendoorn, 1997) Van IJzendoorn, Goldberg, Kroonenberg, & Frenkel (1992).
