Parental reflective functioning in mothers and fathers of preschoolers: Associations with adult attachment and parenting behavior.

Parental reflective functioning (PRF) is considered a key parental competence. Since most research on PRF has focused on infancy or the first years of life, there is a gap in our understanding of PRF among parents of older children. Therefore, we investigated PRF in mothers and fathers with preschool-aged children, examining associations between PRF, parent's romantic attachment, and observed parenting behavior. The sample comprised 50 mothers, 40 fathers, and their 5-year-old children. PRF was assessed using the parental reflective functioning questionnaire (PRFQ), parental romantic attachment was assessed using the experiences in close relationships scale-revised (ECR-R), and parenting behavior was assessed during a parent-child free-play interaction with the coding interactive behavior (CIB) coding system. Results showed that mothers scored higher on the interest and curiosity scale than fathers, indicating that mothers show a more active interest and curiosity in their child's mental states. Further, higher levels of attachment anxiety in fathers were associated with higher levels of pre-mentalizing modes. In mothers, higher levels of attachment avoidance were associated with lower levels of interest and curiosity. Finally, and unexpectedly, higher levels of interest and curiosity in mothers were associated with less sensitivity during free play. In summary, the study found meaningful associations between mothers' and fathers' romantic attachment and their PRF indicating a spill-over of their attachment strategies into their relationship with their child. Further, the study results suggest that very high levels of interest and curiosity in mothers reflect hypermentalizing.

A randomized trial of the Caregiver Interaction Profile (CIP) training with childcare providers: the Copenhagen Daycare Project study protocol.

BACKGROUND: Most young children (0-3 years) attend formal childcare in Denmark, many of them fulltime. Yet recent reports of the quality of Danish childcare centers have shown that in more than one-third of nurseries, the interactions between caregivers and young children (0-3 years) are of "insufficient" quality, which constitutes a risk for affected children's well-being and development. Effective interventions to improve childcare providers' interactive skills are necessary. METHODS: In this randomized controlled trial, we test the effectiveness of the Caregiver Interaction Profile training, which focuses on improving six core interactive skills: sensitive responsiveness, respecting children's autonomy, structuring and limit setting, verbal communication, developmental stimulation, and fostering positive peer interactions. We will recruit N = 200 childcare providers from nursery groups in Copenhagen (n = 100 training group, n = 100 waiting-list control group). Our primary outcomes are childcare providers' six interactive skills named above, observed from video-recorded interactions in the nursery groups. The secondary goal of our study is to test whether the training boosts children's social-emotional and linguistic development. To this end we aim to recruit N ≈ 500 children from participating childcare providers' nursery groups (n ≈ 250 training group, n ≈ 250 waiting-list control group). We measure social-emotional and linguistic development with various standardized questionnaires, filled out by parents and childcare providers. DISCUSSION: If the training is effective at improving childcare providers' interactive skills, then this will be an important foundation for implementation efforts, such as offering the training as part of the educational program of childcare providers. Future research should also evaluate whether the Caregiver Interaction Profile training is effective for childcare providers of older children (3-5 years) in Danish kindergartens. TRIAL REGISTRATION: This trial is registered at clinicaltrials.gov as "Testing the Effects of the Caregiver Interaction Profile Training on the Interactive Skills of Daycare Providers (CDP)" with registry ID NCT05654116.

The significance of parental mentalizing for four-year-old children's solitary pretend play.

BACKGROUND: Pretend play is a signature behavior of early childhood and is considered to reflect the child's emerging symbolic function, enabling the interpretation of social signals, language development, and emotion understanding. While theory links parental mentalizing with children's pretend play, only a few studies have investigated this association. These studies are limited to infancy and early toddlerhood, and child pretend play is assessed during play with an adult (social play). Based on the assumption that child solitary pretend play reflects the child's 'baseline' pretend play ability, in this study, we investigated children's pretend play at its peak, i.e., during the preschool age, without the facilitation of another player. The overall objective was to investigate if parental mentalizing increases pretend play complexity in children. METHODS: The sample consisted 99 Danish mothers and their 4-year-old children. Employing a cross-sectional design, we hypothesized that parental mental state language, as an indicator of 'online' mentalizing during interaction with the child, is a mechanism through which 'offline' mentalizing, measured as parental reflective functioning, is associated with child solitary pretend play. Child pretend play complexity was observed and coded with an adapted version of the 12-Step Play Scale. Maternal offline mentalizing was assessed with the Parental Reflective Functioning Questionnaire, and maternal online mentalizing was assessed by coding the mothers' mental state language during interaction with the child using a modified version of the mind-mindedness coding scheme. RESULTS: While there was no direct effect of maternal offline reflective functioning on child pretend play, online mental state language mediated the link between offline maternal reflective functioning and child pretend play. CONCLUSIONS: These results provide support for the theoretically assumed link between parental mentalizing and children's capacity for pretend play. Furthermore, our study contributes to the literature on parental mentalization, suggesting that parental mentalizing facilitates child development only if the parent can translate this ability into 'mentalizing in action'.

Four-year-old children's pretend play complexity during free play and story stem play and associations with maternal sensitivity.

Theory and research have linked pretend play in early childhood with the development of language and theory of mind. In 102 mother-child dyads at 4.5 years, we examined whether (1) introducing a story stem (a play narrative with socioemotional dilemmas) in a mother-child play context increases pretend play complexity compared with mother-child free play; and (2) maternal sensitivity is associated with pretend play complexity. Further, we explored whether the story stem increased child pretend play complexity more in dyads with mothers with low sensitivity compared with highly sensitive mothers. Sensitivity was coded using Coding Interactive Behavior and pretend play complexity with a global, integrated measure of the developmental level and quantity of play. Using generalized estimating equations, we found that pretend play complexity was positively associated with introducing a story stem and maternal sensitivity. Mixed methods ancova showed no significant interaction between play situation and maternal sensitivity. The findings stress the importance of maternal sensitivity and participation for play and how introducing a story stem may help promote child pretend play complexity.

Understanding Your Baby: protocol for a controlled parallel group study of a universal home-based educational program for first time parents.

BACKGROUND: Infant mental health represents a significant public health issue. The transition to parenthood provides optimal opportunities for supporting parenting competence. Especially parental mentalization, i.e. the caregiver's ability to notice and interpret the child's behavior in terms of mental states, is important in infancy where the caregiver-infant communication is based solely on the infant's behavioral cues. METHODS: This study evaluates the efficacy of the intervention Understanding Your Baby (UYB) compared to Care As Usual (CAU) in 10 Danish municipalities. UYB aims at promoting parental competence in new parents by supporting them in noticing their infants' behavioral cues and interpreting them in terms of mental states. Participants will be approximately 1,130 singletons and their parents. Inclusion criteria are first-time parents, minimum 18 years old, living in one of the 10 municipalities, and registered in the Danish Civil Registration Register (CPR). Around 230 health visitors deliver the UYB as part of their routine observation of infant social withdrawal in the Danish home visiting program. During an interaction between the health visitor and the infant, the health visitor articulates specific infant behaviors and helps the caregivers interpret these behaviors to mental states. The study is a controlled parallel group study with data obtained at four time points in two phases: First in the control group receiving the publicly available postnatal care (CAU), secondly in the intervention group after UYB implementation into the existing postnatal services. The primary outcome is maternal competence. Secondary measures include paternal competence, parental stress, parental mentalizing, and infant socioemotional development. Analysis will employ survey data and data from the health visitors' register. DISCUSSION: Results will provide evidence regarding the efficacy of UYB in promoting parenting competences. If proved effective, the study will represent a notable advance to initiating the UYB intervention as part of a better infant mental health strategy in Denmark. Conversely, if UYB is inferior to CAU, this is also important knowledge in regard to promoting parenting competence and infant mental health in a general population.

Promoting interactive skills and mind-mindedness among early childcare professionals: study protocol for a randomized wait-list controlled trial comparing the Circle of Security approach with care as usual in center-based childcare (the SECURE project).

BACKGROUND: In countries where the majority of young children are enrolled in professional childcare, the childcare setting constitutes an important part of children's caregiving environment. Research consistently shows that particularly the quality of the daily interactions and relationship between young children and their professional caregivers have long-term effects on a range of developmental child outcomes. Therefore, professional caregivers' capacity for establishing high quality interactions with the children in their care is an important target of intervention. METHODS: A prospective, parallel, cluster-randomized wait-list controlled trial is used to test the efficacy of the attachment- and mentalization theory informed Circle of Security (COS) approach adapted to the childcare setting (COS-Classroom) on caregiver interactive skills and mind-mindedness. Participants are professional caregivers of children aged 0-2.9 years working in center-based childcare in Denmark. Approximately 31 childcare centers, corresponding to an estimated 113 caregivers, are expected to participate. The primary outcome is caregiver Sensitive responsiveness measured with the Caregiver Interactive Profile Scales (CIP-scales). Secondary outcomes include caregiver Mind-mindedness, the five remaining CIP-scales (Respect for autonomy, Structure and limit setting, Verbal communication, Developmental stimulation, and Fostering positive peer interactions), and caregivers' resources to cope with work-related stress. Data on structural factors (e.g., staff stability, caregiver-child ratio, and level of pre-service education), caregiver attachment style, acceptability and feasibility of the COS-C together with qualitative data on how the participants experience the COS-C is additionally collected to investigate moderating and confounding effects. DISCUSSION: Examining the effectiveness of the COS-C in center-based childcare contributes to the knowledge of evidence-based intervention programs and can potentially improve the caregiver quality early childcare.

How are mothers negatively affected and supported by following parenting-related Instagram profiles? A mixed-methods study.

Many parents use social media to seek knowledge about child development and parenting, but parents are an understudied population in social media research. In this study, we use a mixed-methods approach to examine mothers' experience of following three different types of Instagram profiles: InstaParents, i.e. influencers sharing their personal experiences with parenthood, professional profiles disseminating knowledge about parenting and child development, and a university-based profile disseminating knowledge about child socioemotional development. The participants were 270 mothers with children aged 0-6 years, who completed an online questionnaire regarding their experience and use of Instagram. Generalized Estimating Equations were used to examine associations between mothers' social comparison orientation and their experience of following the different types of profiles. Content analysis of mothers' responses to open-ended questions was used to examine how mothers were negatively affected and supported by the different profiles. Results showed that mothers with higher levels of social comparison orientation were more negatively affected by following all three types of profiles, but also more supported by following InstaParents. The content analysis suggested that mothers were negatively affected by InstaParents by making upward comparisons and supported by making horizontal comparisons. Mothers were supported by professional profiles, including the university-based profile, by improved knowledge, but these profiles could also lead to a decreased sense of parenting competence. Results inform professionals in relation to how to support mothers through content on Instagram and how to talk to mothers about their digital use and well-being.

Associations between symptoms of maternal postpartum depression, gestational age and infant social withdrawal: A longitudinal study in a community cohort.

Infant social withdrawal is a risk factor for non-optimal child development; thus, it is important to identify risk factors associated with withdrawal. In a large community sample (N = 19,017), we investigate whether symptoms of maternal and partner postpartum depression (PPD; measured with the Edinburgh Postnatal Depression Scale) and prematurity are predictors of infant social withdrawal (measured with the Alarm Distress Baby Scale). Withdrawal was assessed at 2-3, 4-7 and 8-12 months postpartum. Linear regressions showed that prematurity predicted higher infant social withdrawal at all time points, and maternal symptoms of PPD were positively associated with withdrawal at 2-3 months. Logistic regressions showed that odds for elevated social withdrawal were increased with elevated levels of maternal symptoms of PPD at 2-3 and 8-12 months. Partner's symptoms of PPD were not associated with withdrawal. Future studies should investigate how PPD symptoms and prematurity may impact the individual development of social withdrawal.

Reduced prefrontal cortex response to own vs. unknown emotional infant faces in mothers with bipolar disorder.

Motherhood involves functional brain adaptations within a broad neural network purported to underlie sensitive caregiving behavior. Bipolar disorder (BD) is associated with aberrant brain response to emotional faces within a similar network, which may influence BD mothers' sensitivity to infant faces. This functional magnetic resonance imaging (fMRI) study aimed to investigate whether mothers with BD display aberrant neural responses to own infant faces compared to healthy mothers. Twenty-six mothers with BD in remission and 35 healthy mothers underwent fMRI during which they viewed happy and distressed still facial photographs of their own and of unknown infants. After the scan, mothers viewed the pictures again on a computer screen and rated the intensity of infants' facial emotions and their own emotional response to infant face images. Mothers with BD displayed lower left dorsolateral prefrontal cortex (dlPFC) response compared to healthy mothers to own vs. unknown infant faces specifically and abnormal positive functional connectivity between the left and right amygdala and prefrontal regions. BD mothers further displayed stronger deactivation of precuneus and occipital regions to all happy vs. distressed infant faces. After the scan, they rated their infants' distress and own response to their infants' distressed faces less negatively than healthy mothers. Blunted dlPFC response and aberrant fronto-limbic connectivity while viewing own infant faces and less negative ratings of own infants' distress in BD mothers may affect their responses to their own infants in real-life mother-infant interactions.

The impact of childhood adversity on parenting stress is mediated by adult attachment and depressive symptoms.

Adverse childhood experiences can have far-reaching implications for later mental health, including in parenthood. Research suggests that childhood adversity is a risk factor for later parenting stress, yet the underlying mechanisms are only just being uncovered. Uncovering these mechanisms is important to diminish heightened levels of parenting stress and thereby reduce adverse effects of elevated parenting stress on child and parent outcomes. In a cross-sectional study using a sample of mothers of 2-10 month-old infants (N = 367) we first examined depressive symptoms as a mediator, and then, the indirect effect of adult attachment through depressive symptoms between childhood adversity and parenting stress. Results showed that the effect of childhood adversity on parenting stress was mediated by an indirect pathway through depressive symptoms alone, and an indirect pathway of adult attachment through depressive symptoms. The indirect effect of adult attachment through depressive symptoms was found to be stronger than the indirect effect of depressive symptoms alone, supporting the hypothesis that adult attachment insecurity together with depressive symptoms are particularly important risk factors to be considered in this relationship. Results suggest that childhood adversity is a risk factor for parenting stress, and not a determinant of later parenting stress per se. Instead, mediators in this association, adult attachment, and depressive symptoms, were identified as potential targets of intervention to prevent negative effects of childhood adversity on parenting stress. A limitation of the study lies in its cross-sectional design. Future studies should examine these associations longitudinally to allow for interpretation of causality.

Can the Edinburgh Postnatal Depression Scale-3A be used to screen for anxiety?

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.

Processing of infant emotion in mothers with mood disorders and implications for infant development.

BACKGROUND: Atypical neurocognitive responses to emotional stimuli are core features of unipolar depression (UD) and bipolar disorder (BD). For mothers with these mood disorders, this may influence interactions with their infants and consequently infant development. The study aimed to investigate psychophysiological and cognitive responses to infant emotional stimuli, and their relation to mother-infant interaction and infant development, in mothers with BD or UD in full or partial remission. METHODS: Four months after birth, mothers' cognitive responses to emotional infant stimuli were assessed with computerized tasks, while their facial expressions, galvanic skin responses (GSR), gazes, and fixations were recorded. Infant development and mother-infant interactions were also assessed. RESULTS: We included 76 mothers: 27 with BD, 13 with UD, and 36 without known psychiatric disorders, and their infants. Mothers with BD and UD were in full or partial remission and showed blunted GSR and spent less time looking at infant stimuli (unadjusted p values < 0.03). Mothers with BD showed subtle positive neurocognitive biases (unadjusted p values<0.04) and mothers with UD showed negative biases (unadjusted p values < 0.02). Across all mothers, some measures of atypical infant emotion processing correlated with some measures of delays in infant development and suboptimal mother-infant interaction (unadjusted p values<0.04). CONCLUSIONS: Mothers with mood disorders in full or partial remission showed atypical cognitive and psychophysiological response to emotional infant stimuli, which could be associated with mother-infant interactions and infant development. The study is explorative, hypothesis generating, and should be replicated in a larger sample. Investigation of the long-term implications of reduced maternal sensitivity is warranted.

A longitudinal examination of daily amounts of screen time and technoference in infants aged 2-11 months and associations with maternal sociodemographic factors.

This study aimed to examine longitudinal developmental patterns in the daily amounts of screen time and technoference in infants aged 2, 4, 7, and 11 months and to examine associations with maternal sociodemographic factors across all age groups. The results showed that the amount of screen time varied between 6 and 17 min a day, while interruptions in mother-infant interactions due to maternal use of digital technology occurred between 5 and 6 times a day. There was a significant increase in infant screen time from 2 to 4 months, from 4-7 months, and from 7-11 months, and in technoference from 2 to 4 months and from 4-7 months. Maternal age and household income were not associated with infant screen time, but maternal educational level was negatively associated with infant screen time throughout the first year. No associations were found between technoference and maternal age, maternal educational level, or household income. Future research focusing on infant screen time and technoference should aim at including samples that reflect the general population, include measures of screen time and technoference that do not rely on parental report, and include measures of the effects of early infant screen time and technoference on later development.

Temporal coordination between maternal looming and infant gaze in depressed and nondepressed dyads: A bootstrapping approach.

In this study, we examine the convergent validity of a measure of maternal looming derived using a motion capture system, and the temporal coordination between maternal loom and infant gaze using an event-based bootstrapping procedure. The sample comprised 26 mothers diagnosed with postpartum depression, 43 nondepressed mothers, and their 4-month-old infants. Mother-infant interactions were recorded during a standard face-to-face setting using video cameras and a motion capture system. First, results showed that maternal looming was correlated with a globally coded measure of maternal overriding. Maternal overriding is an intrusive behavior occurring when the mother re-directs the infant's attention to parent-led activities. Thus, this result confirms that maternal looming can be considered a spatial intrusion in early interactions. Second, results showed that compared to nondepressed dyads, depressed dyads were more likely to coordinate maternal loom and infant gaze in a Loom-in-Gaze-pattern. We discuss the use of automated measurement for analyzing mother-infant interactions, and how the Loom-in-Gaze pattern can be interpreted as a disturbance in infant self-regulation.

How to screen for social withdrawal in primary care: An evaluation of the alarm distress baby scale using item response theory.

Background: Early identification of infants at-risk is imperative for proper referral to intervention programs. The Alarm Distress Baby Scale (ADBB) is an eight-item observer-rated screening tool detecting social withdrawal in infants. Previously, a shortened five-item version of the scale (m-ADBB) has been proposed. To date, few studies have examined the validity of the two scales, and no studies have examined the validity of the ADBB after implementation as a universal screening tool in primary care. Objective: The aim of this study is to use Item Response Theory (IRT) to examine the construct validity of the ADBB when used by public health visitors in primary care. Methods: Participants were 24,752 infants (aged: 2-12.9 months) screened by public health visitors using the ADBB. Screenings were categorized into three waves according to the infant's age at the screening time (2-3.9 months, 4-7.9 months, and 8-12.9 months). Analyses were conducted separately on each wave. We checked IRT assumptions: (a) Unidimensionality, (b) Monotonicity, (c) Local independence, and (d) No DIF in relation to infant sex and gestational age. The 2PLM was used to assess model fit and estimate model parameters. Results: Items fulfilled assumptions regarding unidimensionality, monotonicity, and no clinical and significant DIF. Local independence was not present for all items (i.e. 2, 7, and 8). The items showed moderate to good discriminatory abilities (alpha values ≥ 1.11) and discriminated best above average levels of social withdrawal (theta values ≥ 1.33). Items 7 and 8 showed nearly identical ICC suggesting that the two items discriminate equally well at the same level of social withdrawal. In addition, items 4 and 6 discriminated best at very high levels of social withdrawal, which might be of limited interest for screening purposes. Finally, the items showed similar patterns in terms of discrimination and location parameters across the three waves. Conclusions: The ADBB shows several psychometric strengths when used by public health visitors in primary care, and the items show good discriminatory abilities at the levels of social withdrawal of interest for screening purposes. Yet, the results also suggest that for first-line screening, the validity of the scale might be improved with the removal of items 4, 6, and 8 as suggested in the m-ADBB. However, before recommending implementation of the m-ADBB, studies comparing the criterion-related validity of the two scales are needed.

Motor activity and spatial proximity: Relationships to infant emotions and maternal postpartum depression.

The ability to express emotions is a protective factor for infant development. Despite the multimodal nature of emotion expression, research has mainly focused on facial expressions of emotions. The present study examined motor activity and spatial proximity in relation to positive and negative infant facial expressions and maternal postpartum depression during face-to-face interactions at four months. Video cameras and a motion capture system recorded mother-infant interactions. Repeated measures ANOVAs were conducted to analyze the effect of micro-coded infant positive and negative facial affect and maternal depression diagnosis on automatically extracted measures of motor activity and spatial proximity, including speed of mothers' arm movements (nondepressed = 32; PPD = 16), and infants' arm movements (nondepressed = 29; PPD = 17), and head distance (nondepressed = 45; PPD = 27). Results showed that the speed of infants' arm movements and head distance were greater during negative compared to positive infant affect. Further, the results demonstrated that the speed of PPD mothers' arm movements was slower than the speed of nondepressed mothers' arm movements. In the discussion, it is suggested that increased speed of infant arm movements during negative affect functions to elicit faster caregiving responses, and that increased head distance during negative infant affect functions to decrease the intensity of the interaction. Finally, the slower speed of arm movements in PPD mothers suggests psychomotor retardation, which is proposed to limit these mothers' abilities to engage their infants during the interaction.

Shaping of Reach-to-Grasp Kinematics by Intentions: A Meta-Analysis.

When we reach to grasp something, we need to take into account both the properties of the object we are grasping and the intention we have in mind. Previous research has found these constraints to be visible in the reach-to-grasp kinematics, but there is no consensus on which kinematic parameters are the most sensitive. To examine this, a systematic literature search and meta-analyses were performed. The search identified studies assessing how changes in either an object property or a prior intention affect reach-to-grasp kinematics in healthy participants. Hereafter, meta-analyses were conducted using a restricted maximum likelihood random effect model. The meta-analyses showed that changes in both object properties and prior intentions affected reach-to-grasp kinematics. Based on these results, the authors argue for a tripartition of the reach-to-grasp movement in which the accelerating part of the reach is primarily associated with transporting the hand to the object (i.e., extrinsic object properties), the decelerating part of the reach is used as a preparation for object manipulation (i.e., prepare the grasp or the subsequent action), and the grasp is associated with manipulating the object's intrinsic properties, especially object size.

Mutual regulation between infant facial affect and maternal touch in depressed and nondepressed dyads.

The ability to regulate affect is important for later adaptive child development. In the first months of life, infants have limited resources for regulating their own affects (e.g. by gaze aversion), and for this reason they are dependent on external affect regulation from their parents. Previous research suggests that touch is an important means through which parents regulate their infants' affects. Also, previous research has shown that post-partum depressed (PPD) mothers and nonclinical mothers differ in their touching behaviors when interacting with their infants. We examined the affect-regulating function of affectionate, caregiving and playful maternal touch in 24 PPD and 47 nonclinical mother-infant dyads when infants were four months old. In order to investigate the direction of effects and to account for repeated observations, the data were analysed using time-window sequential analysis and Generalized Estimating Equations. The results showed that mothers adapt their touching behaviors according to negative infant facial affect; thus, when the infant displays negative facial affect, the mothers were less likely to initiate playful touch and more likely to initiate caregiving touch. Unexpectedly, only in the PPD dyads, were the mothers more likely to initiate affectionate touch when their infants were displaying negative facial affect. Our results also showed that mothers use specific touch types to regulate infants' negative and positive affects; infants are more likely to initiate positive affect during periods with playful touch, and more likely to terminate negative affect during periods with caregiving touch.

Maternal touch in caregiving behavior of mothers with and without postpartum depression.

The way a mother touches her infant plays a central role in maternal caregiving behavior. Thus, the purpose of the present study was to examine associations between touch and positive and negative caregiving behavior and whether this association differed in mothers with and without postpartum depression, an episode of depressive disorder following childbirth. Positive caregiving behavior was operationalized as sensitive behavior, i.e. the mother's ability to notice the child's signals, interpret these signals correctly and respond to them promptly and appropriately. Negative caregiving behavior was operationalized as overriding behavior, i.e. behavior which disturbs the child's behavior or redirects the child's attention to follow the parent's agenda. Seventy mother-infant dyads (44 in the nonclinical group and 26 in the clinical group) participated in a 10minutes long mother-infant interaction at four months postpartum. The sample is part of an archival dataset of a longitudinal study investigating the parent-child relationship and child development. Three minutes of the interaction were coded a) microanalytically for touch, using a modified version of the Maternal Touch Scale (Beebe et al., 2010), and b) macroanalytically for sensitive and overriding behavior, using the Coding Interactive Behavior measure (Feldman, 1998). Hierarchical regression analyses with bootstrapping showed that caregiving touch, but not affectionate and static touch, was associated with sensitive behavior across the whole sample. Moreover, playful, but not rough-intrusive touch, was associated with overriding behavior across the whole sample. Associations did not differ between mothers with and without postpartum depression.

Relations between Automatically Extracted Motion Features and the Quality of Mother-Infant Interactions at 4 and 13 Months.

Bodily movements are an essential component of social interactions. However, the role of movement in early mother-infant interaction has received little attention in the research literature. The aim of the present study was to investigate the relationship between automatically extracted motion features and interaction quality in mother-infant interactions at 4 and 13 months. The sample consisted of 19 mother-infant dyads at 4 months and 33 mother-infant dyads at 13 months. The coding system Coding Interactive Behavior (CIB) was used for rating the quality of the interactions. Kinetic energy of upper-body, arms and head motion was calculated and used as segmentation in order to extract coarse- and fine-grained motion features. Spearman correlations were conducted between the composites derived from the CIB and the coarse- and fine-grained motion features. At both 4 and 13 months, longer durations of maternal arm motion and infant upper-body motion were associated with more aversive interactions, i.e., more parent-led interactions and more infant negativity. Further, at 4 months, the amount of motion silence was related to more adaptive interactions, i.e., more sensitive and child-led interactions. Analyses of the fine-grained motion features showed that if the mother coordinates her head movements with her infant's head movements, the interaction is rated as more adaptive in terms of less infant negativity and less dyadic negative states. We found more and stronger correlations between the motion features and the interaction qualities at 4 compared to 13 months. These results highlight that motion features are related to the quality of mother-infant interactions. Factors such as infant age and interaction set-up are likely to modify the meaning and importance of different motion features.
