Reflective functioning refers to the essential human capacity to understand behavior in light of underlying mental states and intentions. The construct, introduced by Fonagy, Steele, Steele, Moran, and Higgitt in 1991, and elaborated by Fonagy and his colleagues over the course of the next decade, has had an enormous impact on developmental theory and clinical practice. This paper introduces the construct of parental reflective functioning, which refers to the parent's capacity to hold the child's mental states in mind, and begins with a review of Fonagy and his colleagues' essential ideas regarding the reflective function. Next, the applicability of this construct to parental representations of the child and the parent-child relationship is considered. A system for coding parental reflective functioning, which will serve as the organizing framework for this special issue, is described. Finally, the three papers that make up this special section are introduced.

The notion that maternal reflective functioning, namely the mother's capacity to hold her baby and his mental states in mind, plays a vital role in the intergenerational transmission of attachment is investigated (Fonagy, Gergely, Jurist, & Target, 2002; Fonagy et al., 1995; Slade, this volume). A parent's capacity to understand the nature and function of her own as well as her child's mental states, thus allowing her to create both a physical and psychological experience of comfort and safety for her child, is proposed. In this study of 40 mothers and their babies, maternal reflective functioning is measured using the Parent Development Interview (PDI; Aber, Slade, Berger, Bresgi, & Kaplan, 1985), and scored for reflective functioning using an addendum to Fonagy, Target, Steele, & Steele's (1998) reflective functioning scoring manual (Slade, Bernbach, Grienenberger, Levy, & Locker, 2004). The relations between maternal reflective functioning and both adult (measured in pregnancy) and infant attachment (measured at 14 months) are examined. The findings indicate that relations between adult attachment and parental reflective functioning are significant, as are relations between parental reflective functioning and infant attachment. A preliminary mediation analysis suggests that parental reflective functioning plays a crucial role in the intergenerational transmission of attachment.

In this paper we focus on the first wave of outcomes in a pilot phase randomized control trial of a home-based intervention for infants and their families, Minding the Baby® (MTB), an interdisciplinary, mentalization-based intervention in which home visiting services are provided by a team that includes a nurse practitioner and a clinical social worker. Families are recruited during mother's pregnancy and continue through the child's second birthday. Analyses revealed that intervention families were more likely to be on track with immunization schedules at 12 months, had lower rates of rapid subsequent childbearing, and were less likely to be referred to child protective services. In addition, mother-infant interactions were less likely to be disrupted at 4 months when mothers were teenagers, and all intervention infants were more likely to be securely attached, and less likely to be disorganized in relation to attachment at one year. Finally, mothers’ capacity to reflect on their own and their child's experience improved over the course of the intervention in the most high-risk mothers.

This study examines the link between mental representations and maternal behavior within the intergenerational transmission of attachment. Maternal reflective functioning was hypothesized to predict the quality of mother-infant affective communication based on the AMBIANCE measure. Each of these measures was also considered as a predictor of the quality of infant attachment. The subjects were 45 mothers and their 10-14-month-old infants. Results supported each of the study's major hypotheses. The AMBIANCE measure and the reflective functioning measure had a strong negative correlation. Thus, the level of disruption in mother-infant affective communication was inversely related to the level of maternal reflective functioning. The AMBIANCE measure was also shown to be a very good predictor of infant attachment. Mothers with high AMBIANCE scores were more likely to have infants classified as disorganized or resistant, whereas mothers with low AMBIANCE scores were more likely to have infants classified as secure. A linear regression analysis indicated that maternal behavior mediates the impact of maternal reflective functioning upon infant attachment. Implications for attachment theory and early intervention are explored.

Mothers (N = 125) and their firstborn sons were studied over an 11-month period to examine relations between mothers' representations of their relationships with their children (measured at 15 months by using the Parent Development Interview [PDI]), adult representations of attachment (measured at 12 months by using the Adult Attachment Interview [AAI]), and observed mothering (measured at 15 and 21 months). Results indicate (a) that mothers classified as autonomous on the AAI scored highest on the joy-pleasure/coherence dimension of the PDI and mothers classified as dismissing on the AAI scored highest on the anger dimension of the PDI and (b) that mothers scoring higher on the joy-pleasure/coherence dimension of the PDI engaged in less negative and more positive mothering.
