Parental reflective functioning (PRF) refers to the parent’s capacity to envision mental states in the infant and in themselves as a parent, and to link such underlying mental process with behavior, which is important for parenting sensitivity and child socio-emotional development. Current findings have linked maternal postpartum depression to impaired reflective skills, imposing a risk on the developing mother–infant relationship, but findings are mixed, and studies have generally used extensive methods for investigating PRF. The present study examined the factor structure and measurement invariance of the Danish version of the 18-item self-report Parental Reflective Functioning Questionnaire (PRFQ) in a sample of mothers with and without diagnosed postpartum depression. Moreover, the association between PRF and maternal postpartum depression in mothers with and without comorbid symptoms of personality disorder and/or clinical levels of psychological distress was investigated. Participants included 423 mothers of infants aged 1–11 months. Confirmatory factor analysis supported a three-factor structure of the PRFQ; however, item loadings suggested that a 15-item version was a more accurate measure of PRF in mothers of infants. Multi-group factor analysis of the 15-item PRFQ infant version indicated measurement invariance among mothers with and without diagnosed postpartum depression. Multinomial logistic regression showed that impaired PRF was associated with maternal psychopathology, although only for mothers with postpartum depression combined with other symptoms of psychopathology. These results provide new evidence for the assessment of maternal self-reported reflective skills as measured by a modified infant version of the PRFQ, as well as a more nuanced understanding of how variance in symptomatology is associated with impaired PRF in mothers in the postpartum period in differing ways.

Background Anxiety in the ante- and postnatal period is prevalent, often co-occurs with depression, and can have adverse consequences for the infant. Therefore, perinatal mental health screening programs should not only focus on depression but also on detecting anxiety. However, in many already implemented perinatal screening programs, adding extra screening instruments is not feasible. We examine the utility of a subscale of the Edinburgh Postnatal Depression Scale (EPDS) consisting of items 3, 4, and 5 (EPDS-3A) for detecting anxiety in new mothers. Methods We used confirmatory factor analysis (CFA) to confirm the presence of the EPDS-3A found in a previous study (n = 320) where exploratory factor analysis (EFA) was used. For the CFA we used a sample of new mothers (n = 442) with children aged 2–11 months recruited from the same population from which mothers for the previous study was recruited. Three models were tested and compared. Receiver operating characteristics of the EPDS-3A were investigated in relation to anxiety caseness status on the combined sample (N = 762). Sample weighing was used to match the dataset to the target population. Cross tabulation was used to investigate the proportion of anxiety cases identified by the EPDS-3A above those identified with the total EPDS. Results The presence of the EPDS-3A was confirmed. An EFA-driven, two-dimensional 7-item model showed the best data fit with one factor representing the anxiety subscale consisting of items 3, 4, and 5. An EPDS-3A score of ≥ 5 was the most optimal for identifying cases of anxiety (sensitivity: 70.9; specificity: 92.2; AUC: 0.926). Further, we found that the EPDS-3A identifies an additional 2.5% of anxiety cases that would not have been identified with the total EPDS. Conclusions The EPDS-3A can be used as a time-efficient screening for possible anxiety in ante- and postnatal mothers. However, adding the EPDS-3A to routine screening with the total EPDS does not lead to a substantial increase in the number of women identified. In line with previous studies, this study confirms that the EPDS identifies anxiety in addition to depression. Therefore, assessment and treatment adjusted to the specific emotional difficulties is imperative.

Maternal postpartum depression (PPD) has been found to be related to infant social withdrawal during mother–infant interaction, and this may spill over on infant interactive behavior in other social contexts and impact infant psychosocial development. We investigated whether PPD was associated with infant social withdrawal during interaction with a tester in a psychological test situation and whether infant social withdrawal in the test situation mediated the association between PPD and infant cognitive scores reported in a previous study. Participants were 28 PPD dyads and 41 control dyads. We assessed infant social behavior and cognitive development with the Alarm Distress Baby Scale and the cognitive scale of the Bayley Scales of Infant and Toddler Development, third edition, at four months. More symptoms of maternal depression were associated with more infant social withdrawal. The association between maternal depressive symptoms and cognitive scores was at most partially mediated by infant social withdrawal in the test situation (<29.6%). Our results add to the existing literature on the effects of PPD on infant social behavior in other contexts than the one constituted by the mother. More research is needed to shed light on the mechanisms through which PPD impacts infant cognitive development.

The quality of parent-child interaction has consistently been associated with child psychosocial outcomes. Postnatal depression (PND) and anxiety (PNA) can have an adverse effect on the parent-child interaction. The Coding Interactive Behaviour (CIB) measure has frequently been used to assess parent-infant interaction quality; however, few have investigated the construct validity. The purpose of this study is to: (1) compare two theoretical models and one data-driven model for best fit and to test the best fitting one for measurement invariance among mothers with and without PND, and (2) compare effects of PND and PNA on the mother-infant interactions. The sample consisted of mothers with PND (n = 236) and a subclinical sample of mothers with elevated symptoms of PND but did not meet criteria for a diagnosis (n = 183) and their infants (aged ≤ 6 months). PND was assessed with a diagnostic interview and PNA using a self-report measure. Confirmatory factor analyses showed that the data-driven model, consisting of the composites ‘Maternal Sensitivity’, ‘Child Engagement’, ‘Maternal Social Withdrawal’, and ‘Maternal Controlling Behaviour’, reached the best fit and showed measurement invariance with regard to PND. Factorial ANOVAs showed no effects of PND and PNA on the composites. The study is the first to investigate and find measurement invariance in the CIB, providing evidence of construct validity. The importance of investigating the factor structure of an instrument liable to change due to contextual factors is discussed.

The parents' capacity to reflect upon the psychological processes in their child, termed parental reflective functioning (PRF) can be impaired by parental mental health problems. The present study aimed to investigate the factor structure of an infant version of the Parental Reflective Functioning Questionnaire (PRFQ-I) in a low-risk sample of 259 Danish fathers of 1-11-month-old infants to investigate measurement invariance of the PRFQ-I between fathers and mothers; and to examine the association between PRF and paternal depressive symptoms, psychological distress, and parenting stress. Confirmatory factor analysis supported a three-factor model of the PRFQ-I. Multi-group factor analysis indicated partial measurement invariance. Multiple linear regressions showed that paternal depressive symptoms were not associated with PRF. There was an interaction effect of paternal depressive symptoms and general psychological distress on paternal interest and curiosity in their infant's mental state and certainty of infant mental state. Increased parenting stress was associated with impaired PRF on all three subscales of the PRFQ-I. These results provide further evidence for a multidimensional, brief assessment of paternal reflective skills and insight into how variability in paternal psychological functioning relates to impaired PRF in the postpartum period.
