Effects of infant massage on infant attachment security in a randomized controlled trial

Abstract

Benefits of attachment security have been demonstrated in multiple realms of development, and an extensive body of research has identified some of the antecedents associated with the development of secure attachments. While previous research has indicated that infant massage may support the development of mothers’ attachment to their babies, no published research exists that investigated infants’ attachment security after mothers learn infant massage strokes. This study tested the impact of an infant massage intervention on mothers’ massage frequency and attachment security in infants. Fifty-eight mother-infant dyads were randomly assigned to a treatment (massage, n = 28) or control (education, n = 30) group. Most mothers had preschool aged children participating in Head Start as well as an infant under 8 months of age; the remaining mothers were from the community. Mothers in the treatment group completed 4 weeks of infant massage training using standard strokes from Infant Massage USA, a chapter of the International Association of Infant Massage, headquartered in Sweden. At 12 months, mothers were guided through the standard sorting procedure of the Attachment Q-set (Waters, 1987). The treatment was effective, as 86 % of mothers in the massage group were still massaging their babies at the follow-up, an average of 10 months later, and infants whose mothers massaged them had higher attachment security scores. Surprisingly, 29 % of the mothers in the comparison group reported that they massaged their babies. A treatment X massage frequency ANOVA indicated that 12-month-old infants whose mothers in the treatment group had massaged them more than once per week were more securely attached than infants of mothers who massaged their infants less than once per week and also were more securely attached than infants in the comparison group. However mothers in the control group defined massage, it was not associated with infant attachment security at the follow-up. These results indicate that this inexpensive, easy to implement intervention effectively increased mothers’ ongoing use of infant massage, which in turn predicted more attachment security in their infants. • This RCT investigated the impact of teaching mothers massage on the likelihood that they would continue massaging their infants. • Most treatment mothers continued massaging their infants almost a year after the intervention. • Moms who continued massaging their babies two or more times per week had babies who were more securely attached. • Increasing positive maternal-infant touch can promote attachment in babies. • Infant massage is an easy, inexpensive, and loving way to increase positive touch.
