Maternal postpartum anxiety and the development of infant attachment: The effect of body sensations on infant attachment.

BACKGROUND: Knowledge about the influences of maternal postpartum anxiety disorders (PAD) on infant development is limited. Aim of this present study is to evaluate the influence of PAD on infant attachment. METHODS: In a longitudinal study, self-reported anxiety symptoms of N = 70 mothers (N = 28 with PAD diagnosed according to the DSM-IV, N = 42 controls) were examined in the postpartum period and one year later. Infants' attachment was observed in the Strange Situation Test (SST) at the age of 12-24 months. RESULTS: Results indicate a strong relationship between PAD and infant attachment: infants of mothers with PAD were significantly more likely to be classified as insecure or disorganized than infants of control mothers. Logistic regression analysis led to a significant model with 76.8 % correct classification of infant attachment dependent on the maternal fear of anxiety associated body sensations (OR = 4.848) in the postpartum period. Including maternal sensitivity and interaction behavior, only maternal intrusiveness was additionally associated with infant attachment (ρ = 0.273, p < .05; OR = 45.021, p = .153). LIMITATIONS: Participants were highly educated. Different anxiety disorders included led to a heterogenous sample. Generalization is diminished. Maternal sensitivity was measured on a global scale, and body tension was self-reported. CONCLUSIONS: PAD plays a crucial role in the development of infant attachment. Interaction-focused interventions, helping mothers to decrease intrusiveness, and body-focused interventions, helping mothers to deal with their fear of anxiety symptoms, might be promising pathways to buffer the influence of PAD on infant attachment.

Randomized controlled trial of the Circle of Security-Intensive intervention for mothers with postpartum depression: maternal unresolved attachment moderates changes in sensitivity.

Postpartum depression is related to inadequately sensitive caregiving, putting infants at risk for insecure attachment. Therefore, promoting sensitive maternal caregiving and secure child attachment is particularly important in postpartum depressed mothers and their infants. In this randomized-controlled-trial, we evaluated the efficacy of the Circle of Security-Intensive (COS-I)-intervention in supporting maternal sensitivity and mother-infant-attachment compared to treatment-as-usual (TAU) with unresolved-maternal attachment as a moderator of treatment effect. Eligible mothers with infants (N=72) 4-9 months-old were randomly assigned to treatment (n=36 dyads). Infant attachment was rated at follow-up (child age 16-18 months) (Strange-Situation-procedure). Maternal sensitivity was measured at baseline and follow-up (Mini-Maternal-Behavior-Q-sort). Maternal-unresolved-attachment was assessed at baseline (Adult-Attachment-Interview). We found no significant differences between treatments in infant attachment nor changes in mothers' sensitivity. However, in COS-I, unresolved-mothers exhibited significantly more change in sensitivity than non-unresolved-mothers, whereas in TAU, the opposite was true. These findings may help to optimize clinical use of COS-I.

Insightfulness and later infant attachment in clinically depressed and nonclinical mothers.

The aim of this pilot study was to investigate the relationship between maternal insightfulness and sensitivity and subsequent infant attachment security and disorganization in clinically depressed and nonclinical mother-infant groups. Nineteen depressed mothers with infants ages 3 to 11 months participated in this study. Twenty nonclinical mother-infant dyads were matched to the clinical sample according to infant sex and age. Maternal depression was assessed using the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (American Psychiatric Association, 1994), insightfulness using the Insightfulness Assessment (IA), and sensitivity using the Maternal Sensitivity Scales (M.D.S. Ainsworth, 1969). IA classifications and subscales were considered separately. Later infant attachment was assessed by the Strange Situation Procedure (M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978). Depressed mothers tended to have less securely attached children than did nonclinical mothers. Within the clinical sample, the insightfulness categories correlated slightly moderately with attachment security, but were not related to attachment disorganization. Within the nonclinical sample, the IA categories were slightly moderately associated with attachment security and with disorganization. On IA subscales, relationship patterns differed in clinically depressed and nonclinical mother-infant dyads. These findings provide the first evidence of the predictive power of the IA categorization and subscales on subsequent infant attachment. They also may allow the development of different foci of intervention for enhancing insightful caregiving.

Stability of attachment representations during adolescence: the influence of ego-identity status.

The purpose of this study was to examine two core assumptions of attachment theory. First, internal working models of attachment should increase in stability during the course of development. Second, attachment is related to the adaptive solution of stage-salient issues, in adolescence, specifically to identity formation. Adolescence as a developmental period of change and reorganization might lead to changes in attachment representations by re-evaluating one's life experiences in the course of general identity development. In a longitudinal study, the stability of attachment representations (assessed by the Adult Attachment Interview) between ages 16 and 18 was examined. In addition, the concurrent and longitudinal associations of identity status at age 16 with attachment representations at ages 16 and 18 were tested. Results showed high stability of attachment representation during that age period. Secure attachment representation was positively associated with the identity status achievement, whereas a dismissing status was positively associated with identity diffusion. Longitudinally, identity diffusion at age 16 predicted attachment representation at age 18 even after controlling for earlier attachment representation.
