This meta-analysis of maternal sensitivity and infant/toddler attachment security includes 41 studies with 2243 dyads. Its purpose is to explore the impact of time between assessments of maternal sensitivity and attachment security on the strength of association between these two constructs. We also examined the interrelationships between this moderator variable and other moderators identified in the literature, such as age and risk status of the sample. We found an overall effect size of r = .27 linking sensitivity to security. However, time between assessment of sensitivity and attachment security moderates this effect size, such that: (1) effect sizes decrease dramatically as one moves from concurrent to nonconcurrent assessments, and (2) temporally distant assessments are a sufficient condition for small effect size; that is, if the time between assessments is large, then a relatively small effect size linking sensitivity and attachment is certain. We also found that time between sensitivity and attachment assessments may account for earlier findings indicating that effect sizes linking sensitivity to security differ according to age of child and sample risk status. Findings are discussed in terms of internal working models and environmental stability.

Parental perceptions and subjective experience of infants have long been considered important in clinical work with infants and families. Using three different samples of infants, we compare mothers' representations of their infants in clinically referred and nonreferred groups, using the Working Model of the Child Interview (WMCI). Twenty-four mothers of infants with failure to thrive (and 25 matched controls), 17 mothers of toddlers with sleep disorders (and 20 matched controls), and 13 mothers of infants seen in a general infant psychiatry clinic participated. Compared to their nonclinical counterparts, mothers of infants with clinical problems had representations of their infants that were significantly more likely to be classified distorted or disengaged. Infant gender, age, and birth order were independent of maternal classifications. We conclude that the WMCI is a useful structured interview to categorize mothers' perceptions and subjective experience of their infant and relationship with the infant. Mothers' WMCI classifications are associated with the clinical status of the infant. RESUMEN: Las percepciones de la madre y la experiencia subjetiva de los infantes han sido consideradas importantes, desde hace tiempo, en cuanto al trabajo clínico con infantes y familias. En este estudio, presentamos los resultados de una entrevista clínica acerca de las representaciones que las madres tienen de sus infantes y las comparamos con las representaciones de otras madres de infantes que no pertenecen al mismo grupo. Participaron veinticuatro madres de infantes con problemas de crecimiento (y sus 25 parejas de control), 17 madres de infants con trastornos para dormir (y sus 20 parejas de control), y 13 madres de infantes que habían sido vistos en una clínica de siquiatría infantil general. Comparados con sus contrapartes no clínicas, las madres de infantes 107The research was supported in part by the Research Institute of the Hospital for Sick Children.

This study tests the hypothesis that infants with failure to thrive (FTT) are at risk for a clinical disturbance of attachment (defined as a combination of: (1) nonautonomous caregiver state of mind with respect to attachment, measured by the Adult Attachment Interview (AAI); (2) nonbalanced caregiver representation of the infant, measured by the Working Model of the Child Interview (WMCI); (3) problematic play interactions; and (4) problematic feeding interactions). Participants were 57 infants (30 FTT, 27 non‐FTT) and their primary caregivers, recruited from outpatient pediatric clinics. Caregivers were interviewed with AAI and WMCI and observed interacting with their infants during play and feeding. Results show that more infants with FTT than infants without FTT met some of the criteria for risk for a clinical disturbance of attachment —nonautonomous AAI and nonbalanced WMCI classifications, and less dyadic reciprocity during feeding. However, there were no group differences in play. Future directions for research are discussed.
