Effects of a Baby Carrier Intervention on Fathers' Sensitivity, Involvement, and Hormonal Levels: Follow-Up of a Randomized Controlled Study.

Fathers are of great importance for healthy child development. This randomized controlled study investigated the longer-term effects of an intervention using a soft baby carrier on fathers' observed sensitive caregiving, involvement, and oxytocin and cortisol levels. First-time fathers were randomly assigned to use a baby carrier ( = 41) or baby seat ( = 39) and were asked to use the carrier or seat for at least 6 h per week for 3 weeks.

Examining stress in adolescents' daily lives: Feasibility of triadic paradigms.

How adolescents and their parents cope with adolescent stress is relevant for child well-being. (In)congruencies between parent and child perceptions of child stress may be important sources of information for understanding family functioning. However, research assessing the occurrence of stressful events in adolescents' daily lives from the perspective of both adolescents and their parents is lacking, likely because this type of research comes with numerous challenges.

The prenatal video-feedback intervention to promote positive parenting for expectant fathers (VIPP-PRE): Two case studies.

Although parenting interventions including expectant fathers are scarce, they yield promising results. The Prenatal Video-feedback Intervention to promote Positive Parenting (VIPP-PRE) is a recently developed intervention, that is both manualized and personalized, aiming to enhance paternal sensitivity and involvement before the birth of the baby. Illustrating the intervention process, the current study presents two case studies of expectant fathers receiving VIPP-PRE (clinical trial registration NL62696.

Fathers' sensitive parenting enhanced by prenatal video-feedback: a randomized controlled trial using ultrasound imaging.

Background: The aim of this study was to evaluate an interaction-based prenatal parenting intervention program aimed at promoting parental sensitivity and involvement in expectant fathers using ultrasound images: Prenatal Video-Feedback Intervention to Promote Positive Parenting (VIPP-PRE).

Methods: In this randomized controlled trial, 73 first-time, healthy expectant fathers were enrolled. Participants were randomly assigned to the VIPP-PRE intervention (n = 39) or a dummy intervention (n = 34).

Is paternal oxytocin an oxymoron? Oxytocin, vasopressin, testosterone, oestradiol and cortisol in emerging fatherhood.

How do hormonal levels in men change from pregnancy to after the birth of their firstborn child, and what is the role of oxytocin, alone or in interplay with other hormones, in explaining variance in their parenting quality? We explored in 73 first-time fathers the development of five hormones that have been suggested to play a role in parenting: oxytocin (OT), vasopressin (AVP), testosterone (T), oestradiol (E2) and cortisol (Cort). In an extended group of fathers ( = 152) we examined associations with fathers' behaviour with their 2-month-old infants. OT and E2 showed stability from the prenatal to the postnatal assessments, whereas AVP and T decreased significantly, and Cort decreased marginally.

Child maltreatment affects fathers' response to infant crying, not mediated by cortisol or testosterone.

Parents' ability to appropriately respond to infant crying is essential for parental care and has been found to relate to parents' own childhood experiences. Additionally, childhood experiences can affect endocrine factors, which may subsequently affect behavior. In the current study, preregistered on https://osf.

Effects of oxytocin and vasopressin administration on human fathers' sensitive and challenging parenting: A randomized within-subject controlled trial.

This randomized, double-blind, placebo-controlled within-subject study examined the effects of intranasal administration of oxytocin and vasopressin on fathers' sensitive and challenging parenting behaviors. Furthermore, we examined the moderating role of fathers' early childhood experiences. The sample consisted of 70 fathers with their 2- to 12-month-old infants.

Exploring everyday state attachment dynamics in middle childhood.

The current study explored dynamics of secure state attachment expectations in everyday life in middle childhood, specifically state attachment carry-over and reactivity to experiences of caregiver support in the context of stress. In two independent samples (one community sample, = 123; one adoption sample, = 69), children (8-12 years) daily reported on their state attachment for respectively 14 and 7 consecutive days. Additionally, they reported daily on their experiences of distress and subsequent experiences of caregiver support.

State Attachment Variability: Between- and within-Person Level Associations with Trait Attachment and Psychological Problems.

Research suggests that inter-individual differences in the degree of state attachment variability are related to differences in trait attachment and psychological problems between children. In this study, we tested whether such associations are also relevant at a within-person level, and if so, whether intra-individual fluctuations in the degree of variability were predictive of or predicted by intra-individual fluctuations in trait attachment and psychological problems. Children ( = 152; M = 10.

An empirical test of prototype and revisionist models of attachment stability and change from middle childhood to adolescence: A 6-year longitudinal study.

We examined the prototype v. revisionist models of attachment stability with a five-wave, 6-year, longitudinal study of attachment security from middle childhood to adolescence in a White Western European sample (N = 157; Wave 1 M  = 10.91, SD = 0.

A soft baby carrier intervention enhances amygdala responses to infant crying in fathers: A randomized controlled trial.

New fathers may grow into their parental role through active involvement in childcare. Spending time in physical contact with the child may promote an adaptive transition to fatherhood. In this randomized controlled trial, we tested the effects of a baby carrier intervention on fathers' hormonal and neural functioning.

Attachment and the Development of Depressive Symptoms in Adolescence: The Role of Regulating Positive and Negative Affect.

Although widely accepted, attachment theory's hypothesis that insecure attachment is associated with the development of depressive symptoms through emotion regulation strategies has never been longitudinally tested in adolescence. Additionally, previous research only focused on strategies for regulating negative affect, whereas strategies for regulating positive affect may also serve as a mechanism linking insecure attachment to depressive symptoms. This study aimed to fill these research gaps by testing whether the association between attachment and change in depressive symptoms over time is explained by strategies for regulating negative and positive affect in adolescence.

Exploring the hormonal and neural correlates of paternal protective behavior to their infants.

Infant protection is an important but largely neglected aspect of parental care. Available theory and research suggest that endocrine levels and neural responses might be biological correlates of protective behavior. However, no research to date examined associations between these neurobiological and behavioral aspects.

A learning theory of attachment: Unraveling the black box of attachment development.

Attachment is an inborn behavioral system that is biologically driven and essential for survival. During child development, individual differences in (in)secure attachment emerge. The development of different attachment behaviors has been traditionally explained as a process during which experiences with (lack of) responsive and supportive care are internalized into working models of attachment.

A Further Validation of the Cognitive Bias Modification Effect on Trust in Middle Childhood.

Recent middle childhood research suggests that children's trust in maternal support can be manipulated using Cognitive Bias Modification (CBM) aimed at changing children's interpretation of ambiguous maternal support-related behavior. The current study with 60 children (40 girls, M = 10.62, SD = 1.

Combining oxytocin and cognitive bias modification training in a randomized controlled trial: Effects on trust in maternal support.

Background And Objectives: Research on the social effects of intranasal oxytocin in children is scarce. Oxytocin has been proposed to have clearer beneficial effects when added to social learning paradigms. The current study tested this proposition in middle childhood by assessing effects of cognitive bias modification (CBM) training and oxytocin on trust in maternal support.

No side-effects of single intranasal oxytocin administration in middle childhood.

Background: Despite growing interest in the (therapeutic) use of intranasal oxytocin administration in children, the potential side-effects of intranasal oxytocin have remained largely unclear to date. The current study is the first double-blind randomized controlled trial to examine side-effects following single administration of oxytocin nasal spray in elementary school-aged children.

Methods: One hundred children (8-12 years old) were randomly assigned to receive oxytocin or placebo nasal spray.

The effects of Cognitive Bias Modification training and oxytocin administration on trust in maternal support: study protocol for a randomized controlled trial.

Background: Lack of trust in parental support is a transdiagnostic risk factor for the development of psychological problems throughout the lifespan. Research suggests that children's cognitive attachment representations and related information processing biases could be an important target for interventions aiming to build trust in the parent-child relationship. A paradigm that can alter these biases and increase trust is that of Cognitive Bias Modification (CBM), during which a target processing bias is systematically trained.

Contributions of emotional state and attention to the processing of syntactic agreement errors: evidence from P600.

The classic account of language is that language processing occurs in isolation from other cognitive systems, like perception, motor action, and emotion. The central theme of this paper is the relationship between a participant's emotional state and language comprehension. Does emotional context affect how we process neutral words? Recent studies showed that processing of word meaning - traditionally conceived as an automatic process - is affected by emotional state.
