Costs of Not Getting to Know You: Lower Levels of Parental Reflective Functioning Confer Risk for Maternal Insensitivity and Insecure Infant Attachment.

Parental reflective functioning (PRF) is a robust predictor of parenting sensitivity and secure infant attachment, but its assessment requires extensive resources, limiting its integration into research and clinical practice. The Mini-Parent Reflective Functioning Interview (Mini-PRFI) assesses the parent's capacity to mentalize for his/her 6-month-old infant (rated using the PRF coding system; Slade et al., 2004, PRF coding system and Slade REF, Unpublished protocol, New York, NY: The City University of New York). In the current study, we examined whether Mini-PRFI scores were associated with theoretically related constructs; to establish a point of comparison, we evaluated links between Mini-PRFI scores alongside RF assessed from the Adult Attachment Interview (AAI). Mother-infant dyads (N = 88) completed the AAI before the birth of the infant, the Mini-PRFI and an interaction task (rated for insensitive parental behavior) when infants were 6 months old, as well as the Strange Situation Procedure when infants were 16 months old. Mini-PRFI scores were strongly positively associated with AAI RF and negatively associated with maternal insensitivity. Mini-PRFI scores predicted infant attachment organization (secure/insecure, organized/disorganized) at 16 months, and this effect was mediated by parenting insensitivity. These findings suggest that the Mini-PRFI predicts theoretically related attachment constructs, demonstrating the promise of the Mini-PRFI to increase the accessibility of interview-based PRF measurements to clinicians and researchers. © International Congress of Infant Studies (ICIS).
