Adverse Childhood Experiences: Associations with a Blunted Cortisol Stress Response During Pregnancy.

Introduction: Adverse Childhood Experiences (ACEs) are associated with a range of negative physical and mental health outcomes, yet there is limited research focused on the effect of ACEs on stress responses during pregnancy. Expectant mothers experience an increase in cortisol levels as pregnancy progresses, with this increase having important implications for fetal and early infant development. Little is known about the impact of ACEs on maternal cortisol levels.

Using machine learning to understand age and gender classification based on infant temperament.

Age and gender differences are prominent in the temperament literature, with the former particularly salient in infancy and the latter noted as early as the first year of life. This study represents a meta-analysis utilizing Infant Behavior Questionnaire-Revised (IBQ-R) data collected across multiple laboratories (N = 4438) to overcome limitations of smaller samples in elucidating links among temperament, age, and gender in early childhood. Algorithmic modeling techniques were leveraged to discern the extent to which the 14 IBQ-R subscale scores accurately classified participating children as boys (n = 2,298) and girls (n = 2,093), and into three age groups: youngest (< 24 weeks; n = 1,102), mid-range (24 to 48 weeks; n = 2,557), and oldest (> 48 weeks; n = 779).

From the voices of supervisees: A theoretical model of reflective supervision (Part II).

Empirical study of reflective supervision/consultation (RS/C) has been gaining ground over the past decade. However, much of this literature is focused on the supervisor perspective of what RS/C is, what makes it effective, and how it impacts the work of the supervisee. This paper, Part II of a two-part series, presents a theoretical model of RS/C that was developed from the perspectives and experiences of supervisees who work with infants, young children, and families and participate in either group or individual RS/C.

From the voices of supervisees: What is reflective supervision and how does it support their work? (Part I).

Reflective supervision/consultation (RS/C) is a relationship for learning that embraces reflection and reflective practice strategies. It is considered best practice within the infant and early childhood mental health (IECMH) field. Based on research with supervisors, essential components of RS/C have been operationalized and used to develop evaluative tools.

Maternal and Paternal Warmth Impact Recovery Support and Social Network Composition for Substance Dependent African American and Non-African American Women.

Poor early relationship experiences during the first 16 years of life may negatively impact adults' capacity to establish and utilize social support (Suchman, McMahon, Slade, & Luthar, 2005). This is especially of concern for women with substance use disorders (SUD) for whom social support is associated with recovery maintenance and treatment retention (Gregoire & Snively, 2001). The purpose of this study was to examine the influence of early relationship experiences, specifically paternal and maternal warmth, on recovery related social support and personal network characteristics among African American (AA) and non-AA women in treatment for SUD.

Mindfulness and trauma symptoms predict child abuse potential in risk-exposed, men and women during pregnancy.

Background: Nearly a third of adults report childhood trauma in their youth and approximately 700,000 cases of child maltreatment were reported in 2016. Both history of childhood trauma and current trauma symptoms in adults are linked to child maltreatment, although many trauma-exposed individuals are warm and nurturing parents. Identifying resiliency factors in adults with risk factors for harsh parenting may illuminate new pathways to sensitive parenting.

SEX DIFFERENCES IN THE SOCIAL ECOLOGY OF BREASTFEEDING: A MIXED METHODS ANALYSIS OF THE BREASTFEEDING VIEWS OF EXPECTANT MOTHERS AND FATHERS IN THE US EXPOSED TO ADVERSITY.

Despite the significant health benefits of breastfeeding for the mother and the infant, economic class and race disparities in breastfeeding rates persist. Support for breastfeeding from the father of the infant is associated with higher rates of breastfeeding initiation. However, little is known about the factors that may promote or deter father support of breastfeeding, especially in fathers exposed to contextual adversity such as poverty and violence.

Trauma Symptoms and Social Support Mediate the Impact of Violence Exposure on Parenting Competence Among Substance-Dependent Mothers.

Women with substance use disorders (SUDs) experience high rates of violence exposure and posttraumatic stress disorder (PTSD), which are associated with parenting anxiety and lower parenting satisfaction among mothers. Although social support may buffer the impact of violence and PTSD on parenting, violence exposure and PTSD may impair mothers' ability to create, perceive, and utilize social support. We examined the impact of violence exposure, trauma symptoms, and interpersonal support on parenting competence among 291 mothers with substance dependence, using ordinary least squares regression and path analysis.

Acculturative stress and lack of social support predict postpartum depression among U.S. immigrant women of Arabic descent.

Purpose: To examine the relationships among acculturative stress, social support, and postpartum depression (PPD) symptoms among U.S. immigrant women of Arabic descent; and to examine if social support moderates the associations between acculturative stress and PPD symptoms.

Depressive and trauma symptoms in expectant, risk-exposed, mothers and fathers: Is mindfulness a buffer?

Background: Perinatal depression is reported in 15-20% of women (Marcus, 2009), 8-16% of men (Paulson and Bazemore, 2010) and low-SES, diverse populations are particularly at risk (Sareen, 2011). Trauma symptoms are commonly comorbid with depression, especially when individuals are exposed to risk factors such as community violence and poverty (Kastello et al., 2015; WenzGross et al.

MIXED-METHODS EVALUATION OF PARTICIPANT RECRUITMENT AND RETENTION IN THE MOM POWER PARENTING INTERVENTION PROGRAM.

Parenting group success begins with attendance. Using archival pilot data from 99 mothers who enrolled in the Mom Power (MP) parenting intervention, this study sought to understand the factors that influenced participant engagement and retention. MP is a group-based, early intervention program grounded in attachment theory that utilizes motivational interviewing as a core component to enhance program engagement.

Parent-child intervention decreases stress and increases maternal brain activity and connectivity during own baby-cry: An exploratory study.

Parental responses to their children are crucially influenced by stress. However, brain-based mechanistic understanding of the adverse effects of parenting stress and benefits of therapeutic interventions is lacking. We studied maternal brain responses to salient child signals as a function of Mom Power (MP), an attachment-based parenting intervention established to decrease maternal distress.

DEVELOPMENT AND SOCIALIZATION OF PHYSICAL AGGRESSION IN VERY YOUNG BOYS.

The expression of physical aggression is normative in early child development; it peaks in the second year of life, with steep declines for most children by the third and fourth years as children learn alternatives to aggression. Some children, however, fail to demonstrate declines in aggressive acts, and many of these are boys. The current review uses a dynamic systems (DS) approach to identify early individual and contextual factors that may dynamically influence trajectories of aggression as a characteristic way of engaging within communities and relationships.

The influence of interpersonal aggression on maternal perceptions of infant emotions: Associations with early parenting quality.

The current study tested the hypothesis that mothers who have experienced child maltreatment and aggression within their adult relationships may be at particular risk for misinterpreting infant emotions, leading to less sensitive parenting behaviors. Participants were 120 pregnant women recruited for a larger, longitudinal study investigating the role of psychosocial and environmental risk on women and their young children. Data were collected during the third trimester of pregnancy, and when children were 1 and 2 years of age.

What is the container/contained when there are ghosts in the nursery?: Joining Bion and Fraiberg in dyadic interventions with mother and infant.

"Ghosts in the nursery." "Visitors from the unremembered past." Fraiberg, Adelson, and Shapiro's (1975) words convey the relational "intruders" that they perceived while working with mothers and infants.

Strong, safe, and secure: negotiating early fathering and military service across the deployment cycle.

Military fathers of young children often endure repeated separations from their children, and these may disrupt the early parent-child relationship. Postdeployment reunification also poses challenges; disruptions that have occurred must often be repaired in the context of heightened emotions on the part of each family member at a time when fathers are themselves readjusting to the routines and responsibilities of family life. The current study employed qualitative research with the central aim of informing a richer understanding of these experiences.

Maternal sensitivity and latency to positive emotion following challenge: pathways through effortful control.

The ability to self-generate positive emotions is an important component of emotion regulation. In this study, we focus on children's latency to express positive emotions following challenging situations and assess whether this ability operates through early maternal sensitivity and children's effortful control. Longitudinal relations between maternal sensitivity, infant negative affect, effortful control, and latency to positive emotion following challenge were examined in 156 children who were 33 months of age.

Hush now baby: mothers' and fathers' strategies for soothing their infants and associated parenting outcomes.

Objectives: The purpose of this study was to examine the types of soothing behaviors used by mothers and fathers of infants, differences in use trajectories over time, and associated parenting outcomes.

Methods: A longitudinal study of 241 families expecting their second child was performed. Data were collected at 1, 4, and 8 postnatal months and included measures of parental soothing techniques, involvement in soothing, distress in response to infant crying, and parenting self-efficacy.

Fathering after military deployment: parenting challenges and goals of fathers of young children.

Although often eagerly anticipated, reunification after deployment poses challenges for families, including adjusting to the parent-soldier's return, re-establishing roles and routines, and the potentially necessary accommodation to combat-related injuries or psychological effects. Fourteen male service members, previously deployed to a combat zone, parent to at least one child under seven years of age, were interviewed about their relationships with their young children. Principles of grounded theory guided data analysis to identify key themes related to parenting young children after deployment.

Maternal parenting predicts infant biobehavioral regulation among women with a history of childhood maltreatment.

Early biobehavioral regulation, a major influence of later adaptation, develops through dyadic interactions with caregivers. Thus, identification of maternal characteristics that can ameliorate or exacerbate infants' innate vulnerabilities is key for infant well-being and long-term healthy development. The present study evaluated the influence of maternal parenting, postpartum psychopathology, history of childhood maltreatment, and demographic risk on infant behavioral and physiological (i.

Toward a neuroscience of interactive parent-infant dyad empathy.

In accord with social neuroscience's progression to include interactive experimental paradigms, parents' brains have been activated by emotionally charged infant stimuli - especially of their own infant - including baby cry and picture. More recent research includes the use of brief video clips and opportunities for maternal response. Among brain systems important to parenting are those involved in empathy.

Parental brain and socioeconomic epigenetic effects in human development.

Critically significant parental effects in behavioral genetics may be partly understood as a consequence of maternal brain structure and function of caregiving systems recently studied in humans as well as rodents. Key parental brain areas regulate emotions, motivation/reward, and decision making, as well as more complex social-cognitive circuits. Additional key environmental factors must include socioeconomic status and paternal brain physiology.

Parenting and Beyond: Common Neurocircuits Underlying Parental and Altruistic Caregiving.

Interpersonal relationships constitute the foundation on which human society is based. The infant-caregiver bond is the earliest and most influential of these relationships. Driven by evolutionary pressure for survival, parents feel compelled to provide care to their biological offspring.

Understanding the "ghosts in the nursery" of pregnant women experiencing domestic violence: Prenatal maternal representations and histories of childhood maltreatment.

Selma Fraiberg and colleagues (1975) conceptualized the "ghosts in the nursery" as experiences from a mother's past that influenced her ability to form a warm and attuned relationship with her child. Contemporary infant mental health interventions often ask the mother to reflect on her own history of attachment relationships to gain insight into as well as to strengthen her developing relationship with her child. This study investigated the association between a mother's history of childhood maltreatment (CM) and her subsequent prenatal maternal representation during the third trimester of pregnancy.
