ABSTRACT
INTRODUCTION: Parental Reflective Functioning describes the parents’ ability to view their child as motivated by mental states. The Parental Reflective Functioning Questionnaire (PRFQ) represents an 18-item and three-factor self-report measure. Our goal was to conduct the first German validation study.
METHOD: In a community sample of 378 mothers of children aged 10.2-78.6 months, we used Confirmatory Factor Analysis with a cross-validation approach to assess model fit. Reliability was measured using Cronbach’s α and McDonald’s ω. Concurrent validity was assessed using correlations with relevant constructs.
RESULTS: The three-factor structure of the original validation could be confirmed. The German model only needed minor modifications: two items had to be removed, and one error covariance was added. The resulting 16-item questionnaire with the three subscales “Pre-mentalizing”, “Interest and Curiosity about Mental States”, and “Certainty about Mental States” was successfully cross-validated (CFI = .94, TLI = .93, SRMR = .07, RMSEA = .04 (CI [.01, .06])). These factors were related in theoretically expected ways to parental attachment dimensions, emotional availability, parenting stress, and infant attachment status.
CONCLUSION: While reliability could still be improved, the German 16-item version of the PRFQ represents a valid measure of parental reflective functioning.
