RESUMEN
OBJECTIVE: This study investigated the influence of maternal reflective functioning (RF) on 6-month-old infants' emotional self-regulating abilities in preterm infant-mother dyads. METHODS: 25 preterm (gestational age 28-34.5 weeks) infants' affect, gaze toward mother, and self-soothing behaviors (thumb-sucking and playing with clothing) were measured during the still-face procedure at 6 months corrected age. Maternal RF was measured at 7-15 days post-delivery using the Parent Development Interview. RESULTS: Infants with high RF mothers showed the most negative affect during the still-face episode (M = 21.33s, SE = 5.44), whereas infants with low RF mothers showed the most negative affect in the reunion episode (M = 18.14s, SE = 3.69). Infants with high RF mothers showed significantly more self-soothing behaviors when distressed (Ms > 14.5s) than infants with low RF mothers (Ms < 1s), p's < .01. CONCLUSION: Maternal RF was associated with infants' self-regulating behavior, providing preliminary evidence for the regulatory role of maternal RF in preterm infants' emotion regulation capacity.
