Parental reflective functioning and theory of mind acquisition: A developmental perspective.

This study investigated theory of mind (ToM) development in 83 children aged 3-5 years and its associations with parental reflective functioning (PRF), using a multidimensional and developmental approach. Results showed that ToM dimensions (i.e., affective, belief-desire, and cognitive) gradually increased with age. All dimensions of PRF (i.e., prementalizing modes, certainty about mental states, and interest and curiosity in mental states) were associated with ToM dimensions, with different dimensions being differentially related to ToM, including age-related effects.

Assessing reflective functioning in prospective adoptive parents.

The capacity for reflective functioning (RF) or mentalizing of adoptive parents is hypothesized to play an important role in fostering socio-emotional development in adopted children. This paper reports on the development and preliminary validation of the Adoption Expectations Interview (AEI), a semi-structured interview to assess RF in prospective adoptive parents. The AEI was developed based on the Pregnancy Interview, Parent Development Interview, and Working Model of the Child Interview, three interviews that have been used to assess RF in biological parents, to capture RF before child arrival in prospective adoptive parents. In a sample of 96 prospective adoptive parents, the Reflective Functioning Scale, as applied to the AEI (AEI-RFS) showed good reliability, with strong correlations between the different demand items, high internal consistency, and good to excellent inter-rater reliability. A principal component analysis yielded one component, suggesting that the items measured a unidimensional factor. Preliminary evidence for the construct validity of the AEI-RFS was demonstrated by significant associations between the AEI-RFS and well-validated measures of mentalizing, attachment dimensions, and interpersonal functioning.

The parental reflective functioning questionnaire: Development and preliminary validation.

This paper reports on three studies on the development and validation of the Parental Reflective Functioning Questionnaire (PRFQ), a brief, multidimensional self-report measure that assesses parental reflective functioning or mentalizing, that is, the capacity to treat the infant as a psychological agent. Study 1 investigated the factor structure, reliability, and relationships of the PRFQ with demographic features, symptomatic distress, attachment dimensions, and emotional availability in a socially diverse sample of 299 mothers of a child aged 0-3. In Study 2, the factorial invariance of the PRFQ in mothers and fathers was investigated in a sample of 153 first-time parents, and relationships with demographic features, symptomatic distress, attachment dimensions, and parenting stress were investigated. Study 3 investigated the relationship between the PRFQ and infant attachment classification as assessed with the Strange Situation Procedure (SSP) in a sample of 136 community mothers and their infants. Exploratory and confirmatory factor analyses suggested three theoretically consistent factors assessing pre-mentalizing modes, certainty about the mental states of the infant, and interest and curiosity in the mental states of the infant. These factors were generally related in theoretically expected ways to parental attachment dimensions, emotional availability, parenting stress, and infant attachment status in the SSP. Yet, at the same time, more research on the PRFQ is needed to further establish its reliability and validity.
