Self‐report measure of parental reflective functioning: A study of reliability and validity across three samples of varying clinical risk

Abstract

AbstractThe Parental Reflective Functioning Questionnaire (PRFQ) provides an efficient way to measure a parent's capacity to recognize their child's mental states and to understand the relationship between underlying mental states and behavior. To date, limited work evaluates its psychometric properties beyond initial validation studies. Here we examined the reliability and validity of the PRFQ in three samples of varying clinical risk (e.g., community sample, previous mental health diagnosis, substance use disorder diagnosis). Across samples, the majority (e.g., 75%–78%) of mothers identified as White; all mothers were from the USA. We compared the PRFQ to task‐based measures of mentalization, the Parent Development Interview (PDI), and measures of the parent‐child relationship. The PRFQ was a reliable measure across samples, and it was associated in theoretically consistent ways with task‐based measures of mentalization. Parental RF across the PDI and PRFQ were not highly correlated in a sample of mothers with substance use disorders. Existing RF measures may be tapping into a different component of the broader construct of parental reflective functioning (PRF). The PRFQ was further validated by demonstrating relationships with parent‐report measures of the parent‐child relationship. Taken together, these findings provide additional support for the reliability and validity of the PRFQ.
