Maternal Sensitivity and Child Secure Base Use in Early Childhood: Studies in Different Cultural Contexts.

This study tested whether maternal sensitivity and child security are related during early childhood and whether such an association is found in different cultural and social contexts. Mother-child dyads (N = 237) from four different countries (Colombia, Mexico, Peru, and the United States) were observed in naturalistic settings when children were between 36 and 72 months of age. Maternal and child behavior during interactions at home and in the playground were described using Q methodology. Findings reveal that across cultures, concurrent maternal sensitivity and more specific behavioral domains of maternal care (e.g., contributions to harmonious interactions and secure base support) are important for children's attachment security during early childhood. Implications for the study of attachment relationships beyond infancy and in diverse contexts are highlighted.

Infant Nutrition and 12 and 18 Months Secure Base Behavior: An Exploratory Study.

A notable omission in studies of developmental links to early nutritional deficiencies is infant attachment. In those few studies investigating associations between infant nutrition and attachment, nutrition was defined solely by physical growth, and infants had moderate-severe growth retardation. In this study, we utilized multiple markers of infant nutrition. Our sample consisted of 172 12-month-old Peruvian infants and their mothers from low-income families, with a follow-up assessment on 77 infants at 18 months. Infants were not severely malnourished, but did have micronutrient deficiencies. Anthropometry, dietary intake, and iron status were used as measures of infant nutrition. Based on infant behavior in a structured laboratory situation, Q-sort techniques were used to rate three attachment markers: infant secure base behavior, interaction quality, and negative emotionality with mother. At 12 months, infant weight was positively related to interaction quality. At 18 months, infant iron status was positively related to secure base behavior. This pattern of findings remained even after statistically controlling for family socioeconomic status and maternal education. Our findings indicate that infant nutritional status is associated with markers of infant attachment and these associations are not restricted just to severely malnourished infants.

Through Colombian lenses: ethnographic and conventional analyses of maternal care and their associations with secure base behavior.

According to attachment theory, the quality of care plays a key role in the organization of infants' secure base behavior across contexts and cultures. Yet information about attachment relationships in a variety of cultures is scarce, and questions remain as to whether Ainsworth's conceptualization of early care quality (sensitivity; M. D. S. Ainsworth, M. C. Blehar, E. Waters, & S. Wall, 1978) is appropriate for characterizing caregiving behavior in different groups and whether culturally specific descriptions of early care are related to conventional measures of maternal sensitivity and to infants' security. In this naturalistic study of mother-infant interactions in Colombia, scores on different domains of maternal care were obtained through ethnographic methodology, and conventional Q-sort scores for maternal and infant behavior were obtained. Findings are discussed in terms of the cross-cultural generality of the sensitivity construct and the sensitivity-security link and of the relevance of naturalistic open-ended studies in different contexts.

Maternal caregiving and infant security in two cultures.

Attachment theory proposes that early care plays a key role in the emergence and organization of secure-base behavior across a wide range of cultures and contexts. Most studies on the topic have been conducted with Caucasian North American and European samples. Research needs to address questions concerning the cross-cultural generality of the sensitivity-security link, the appropriateness of the conceptualization of caregiving offered by attachment theory in other cultures, and the identification of caregiving domains other than those proposed by the theory. The authors address these issues in a study of maternal care and infant security in 2 different countries. Q descriptions of maternal behavior were obtained from observations at home. Infant security was assessed in a laboratory environment in Denver, Colorado and in the home environment in Bogota, Colombia. Findings are discussed in terms of the generality of the sensitivity-security link, the appropriateness of the model of caregiving suggested by attachment theory in both countries, and the relevance of other domains of caregiving to security.
