  • infant Attachment parenting stress and child emotional and behavioral problems at age 3 years
    Parenting: Science and Practice, 2012
    Co-Authors: Anne Tharner, Maartje P C M Luijk, Marinus H Van Ijzendoorn, Marian J Bakermanskranenburg, Vincent W V Jaddoe, Albert Hofman, Frank C Verhulst, Henning Tiemeier
    Abstract:

    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.

  • breastfeeding and its relation to maternal sensitivity and infant Attachment
    Journal of Developmental and Behavioral Pediatrics, 2012
    Co-Authors: Anne Tharner, Marinus H. Van Ijzendoorn, Maartje P C M Luijk, Marian J Bakermanskranenburg, Vincent W V Jaddoe, Albert Hofman, Frank C Verhulst, Hein Raat, Henriette A Moll, Henning Tiemeier
    Abstract:

    Objective: To examine the association of breastfeeding with maternal sensitive responsiveness and infant-mother Attachment security and disorganization. Methods: We included 675 participants of a prospective cohort study. Questionnaires about breastfeeding practices were administered at 2 and 6 months postpartum. At 14 months, maternal sensitive responsiveness was assessed in a 13-minute laboratory procedure using Ainsworth's sensitivity scales, and Attachment quality was assessed with the Strange Situation Procedure. Mothers were genotyped for oxytocin receptor genes OXTR rs53576 and OXTR rs2254298. Linear regressions and analyses of covariance adjusted for various background variables were conducted. We tested for mediation and moderation by maternal sensitive responsiveness and maternal oxytocin receptor genotype. Results: Continuous analyses showed that longer duration of breastfeeding was associated with more maternal sensitive responsiveness (B = 0.11, 95% confidence interval [CI] 0.02; 0.20, p < .05), more Attachment security (B = 0.24, 95% CI = 0.02; 0.46, p < .05), and less Attachment disorganization (B = -0.20, 95% CI -0.36; -0.03, p < .05). Duration of breastfeeding was not related to the risk of insecure-avoidant or insecure-resistant versus secure Attachment Classification, but longer duration of breastfeeding predicted a lower risk of disorganized versus secure Attachment Classification (n = 151; odds ratio [OR] = 0.81, 95% CI 0.66 to 0.99, p = .04). Maternal sensitive responsiveness did not mediate the associations, and maternal oxytocin receptor genotype was not a significant moderator. Conclusions: Although duration of breastfeeding was not associated with differences in infant-mother Attachment Classifications, we found subtle positive associations between duration of breastfeeding and sensitive responsiveness, Attachment security, and disorganization.

  • subcortical structures and the neurobiology of infant Attachment disorganization a longitudinal ultrasound imaging study

    Abstract:

    Attachment disorganization in infancy is a risk factor for behavior problems and other psychopathology. Traditionally the role of parental behavior for qualitative differences in early Attachment relationships has been emphasized. However, disrupted infant-parent interactions only partly explain Attachment disorganization. A complementary focus on child factors such as early differences in the underlying neurobiological systems is needed. We examined whether early structural differences in the gangliothalamic ovoid, comprising the basal ganglia and the thalamus, are involved in the etiology of infant Attachment disorganization. Gangliothalamic ovoid diameter was measured by ultrasound in 6-week-old participants of a prospective population-based cohort study. Attachment Classification of 629 of these infants was assessed with the strange situation at 14 months of age. Neurobiological differences within the normal range were prospectively associated with Attachment disorganization. Infants with a larger gangliothalamic ovoid at 6 weeks had a lower risk of Attachment disorganization at 14 months (OR = 0.73 per SD increase in diameter, 95% CI 0.57-0.93, p <.05). Volume of the lateral ventricles as an index of general brain development was not associated with Attachment disorganization. These findings provide new insight into the etiology of infant Attachment disorganization that may in part be neurodevelopmentally determined.

  • Attachment disorganization moderates the effect of maternal postnatal depressive symptoms on infant autonomic functioning
    Psychophysiology, 2013
    Co-Authors: Anne Tharner, Marinus H. Van Ijzendoorn, Maartje P C M Luijk, Marian J Bakermanskranenburg, Bram Dierckx, Joost R Van Ginkel, Henriette A Moll
    Abstract:

    We examined associations of disorganized Attachment and maternal depressive symptoms with infant autonomic functioning in 450 infant-mother dyads enrolled in the Generation R study. Maternal depressive symptoms were measured 2 months postpartum with the Brief Symptom Inventory. At 14 months, we assessed infant Attachment with a slightly shortened Strange Situation and measured infant resting heart rate. Respiratory sinus arrhythmia (RSA) was calculated using spectral analysis. Higher levels of maternal postnatal depressive symptoms predicted lower resting RSA in disorganized infants (B=-0.31, SE=0.15, p=.04, R2=.05) but not in nondisorganized infants (B=0.05, SE=0.06, p=.36). This effect was buffered in disorganized infants with a secondary secure Attachment Classification. Disorganized infants were more vulnerable to the effect of maternal postnatal depressive symptoms on the physiological stress systems.

  • sleeping out of home in a kibbutz communal arrangement it makes a difference for infant mother Attachment
    Child Development, 1994
    Co-Authors: Abraham Sagi, Marinus H. Van Ijzendoorn, Ora Aviezer, Frank Donnell, Ofra Mayseless
    Abstract:

    Attachment Classification distributions of infant-mother dyads living in 2 types of Israeli kibbutzim were compared. The subjects were 48 infants, 14–22 months old (M= 18.29 months); 13 boys and 10 girls were from 23 kibbutz infants' houses with communal sleeping arrangements, and 13 boys and 12 girls were from 25 kibbutz infants' houses with home-based sleeping arrangements. The 2 groups did not differ on infants' temperament and early life events, mother-infant play interaction, quality of infants' daytime environment, or any of several maternal variables. Among the home-based infants, 80% were securely attached to their mothers versus 48% of the infants in communal sleeping arrangements. No avoidant relationships were found. Including the disorganized-disoriented Attachment Classification (44% in the communal group, 32% in the home-based group) did not change the results. We argue that the communal sleeping arrangement presents a child-rearing environment that deviates markedly from the environment of evolutionary adaptedness.

Duration of breastfeeding was not related to the risk of insecure-avoidant or insecure-resistant versus secure Attachment Classification, but longer duration of breastfeeding predicted a lower risk of disorganized versus secure Attachment Classification (n = 151; odds ratio [OR] = 0.81, 95% CI 0.66 to 0.99, p = .04). Maternal sensitive responsiveness did not mediate the associations, and maternal oxytocin receptor genotype was not a significant moderator. Conclusions: Although duration of breastfeeding was not associated with differences in infant-mother Attachment Classifications, we found subtle positive associations between duration of breastfeeding and sensitive responsiveness, Attachment security, and disorganization.

    Abstract:

    Attachment disorganization in infancy is a risk factor for behavior problems and other psychopathology. Traditionally the role of parental behavior for qualitative differences in early Attachment relationships has been emphasized. However, disrupted infant-parent interactions only partly explain Attachment disorganization. A complementary focus on child factors such as early differences in the underlying neurobiological systems is needed. We examined whether early structural differences in the gangliothalamic ovoid, comprising the basal ganglia and the thalamus, are involved in the etiology of infant Attachment disorganization. Gangliothalamic ovoid diameter was measured by ultrasound in 6-week-old participants of a prospective population-based cohort study. Attachment Classification of 629 of these infants was assessed with the strange situation at 14 months of age. Neurobiological differences within the normal range were prospectively associated with Attachment disorganization. Infants with a larger gangliothalamic ovoid at 6 weeks had a lower risk of Attachment disorganization at 14 months (OR = 0.73 per SD increase in diameter, 95% CI 0.57-0.93, p <.05). Volume of the lateral ventricles as an index of general brain development was not associated with Attachment disorganization. These findings provide new insight into the etiology of infant Attachment disorganization that may in part be neurodevelopmentally determined.
