This study examined the associations among mothers' insightfulness into their infants' internal experience, mothers' sensitivity to their infants' signals, and infants' security of attachment to their mothers. The insightfulness of 129 mothers of 12-month-old infants was assessed by showing mothers 3 videotaped segments of observations of their infants and themselves and interviewing them regarding their infants' and their own thoughts and feelings. Interviews were classified into 1 insightful and 3 noninsightful categories. Mothers' sensitivity was assessed during play sessions at home and at the laboratory, and infant-mother attachment was assessed with the Strange Situation. Mothers classified as positively insightful were rated as more sensitive and were more likely to have securely attached children than were mothers not classified as positively insightful. Insightfulness also accounted for variance in attachment beyond the variance explained by maternal sensitivity. These findings add an important dimension to research on caregiving, suggesting that mothers' seeking of explanations for the motives underlying their infants' behavior is related to both maternal sensitivity and infant attachment.

In the current study (a) maternal insightfulness into the experience of the child and (b) resolution with respect to the child's diagnosis and their associations with children's security of attachment were examined in a sample of 45 preschoolers (mean age = 49 months) with autism spectrum disorders (ASD). It was hypothesized that mothers who were insightful and resolved would be more likely to have securely attached children than mothers who were neither insightful nor resolved. The findings supported this hypothesis. The implications of insightfulness and resolution for child attachment in the context of ASD are discussed.

In the current study we examined the links between maternal sensitivity and children's secure attachment in a sample of 45 preschool-age boys with Autism Spectrum Disorders (ASD). We hypothesized that mothers of securely attached children would be more sensitive to their children than mothers of insecurely attached children. Children's attachment was assessed using Ainsworth's Strange Situation Procedure (SSP; Ainsworth, Blehar, Waters, & Wall, 1978). Mothers' sensitivity and children's responsiveness to their mothers were assessed using the Emotional Availability Scales (Biringen, Robinson, & Emde, 1993). The findings supported our hypothesis: mothers of securely attached children were more sensitive to their children even when controlling for the severity of children's diagnosis (Autism Disorder vs. Pervasive Developmental Disorder - Not Otherwise Specified (PDD-NOS)), children's level of functioning (high vs. low), and children's levels of responsiveness. The significance of sensitivity for security of attachment in ASD and the implications of these findings for the validity of the SSP in children with ASD are discussed.

This study examined the hypothesis that maternal sensitivity mediates the association between maternal Insightfulness/Resolution and child attachment in a sample of preschool age boys with Autism Spectrum Disorders. This study used the Insightfulness Assessment to assess insightfulness and the Reaction to Diagnosis Interview to assess mothers' resolution. Maternal sensitivity was assessed from mother-child play observations, and the security of children's attachment was assessed using the Strange Situation Procedure. The results supported the mediation model, and their implications for attachment research, research on intervention in autism, and clinical work are discussed.
