Abstract
OBJECTIVES: Infant massage (IM) is a well-studied, safe intervention known to benefit infants born preterm. Less is known about the benefits of maternally-administrated infant massage for mothers of preterm infants who often experience increased rates of anxiety and depression in their infants' first year of life. This scoping review summarizes the extent, nature, and type of evidence linking IM and parent-centered outcomes. METHODS: The Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for scoping reviews (PRISMA-ScR) protocol was followed using three databases: PubMed, Embase, and CINAHL. Thirteen manuscripts evaluating 11 separate study cohorts met pre-specified inclusion criteria. RESULTS: Six primary topics related to the influence of infant massage on parent outcomes emerged: 1) anxiety, 2) perceived stress, 3) depressive symptoms, 4) maternal-infant interaction, 5) maternal satisfaction, and 6) maternal competence. Emerging evidence supports that infant massage, when administered by mothers, benefits mothers of preterm infants by reducing anxiety, stress, and depressive symptoms and improving maternal-infant interactions in the short-term, but there is limited evidence to support its effectiveness on these outcomes in longer periods of follow-up. Based on effect size calculations in small study cohorts, maternally-administered IM may have a moderate to large effect size on maternal perceived stress and depressive symptoms. CONCLUSIONS: Maternally-administered IM may benefit mothers of preterm infants by reducing anxiety, stress, depressive symptoms, and by improving maternal-infant interactions in the short-term. Additional research with larger cohorts and robust design is needed to understand the potential relationship between IM and parental outcomes.
