Breaking the maternity mold: navigating the return to work and challenging rigid maternal beliefs through an online psychological intervention.

Working mothers must often balance work and family responsibilities which can be affected by rigid and irrational beliefs about motherhood. The present study had two aims: (a) to provide psychometric evidence for a shortened Italian version of the Rigid Maternal Beliefs Scale (RMBS) and (b) to facilitate mothers' return to work after maternity leave by reducing perceptions of anxiety and stress related to rigid maternal beliefs (i.e., perceptions and societal expectations of mothers, maternal confidence, maternal dichotomy) and by teaching specific recovery strategies (e.g., relaxation, mastery experiences) to manage anxiety and stress through an online psychological intervention. Results replicated the three-factor structure of the original RMBS and showed good psychometric properties. The online psychological intervention resulted in decrease in the rigidity of maternal beliefs, perceived anxiety and stress, and increase in recovery strategies. These initial results are promising and encourage further investigation into online psychological interventions for improving the well-being of working mothers.

Attachment relationship quality with mothers and fathers and child temperament: An individual participant data meta-analysis.

A growing body of research suggests that, compared with single parent-child attachment relationships, child developmental outcomes may be better understood by examining the configurations of child-mother and child-father attachment relationships (i.e., attachment networks). Moreover, some studies have demonstrated an above-chance level chance of concordance between the quality of child-mother and child-father attachment relationships, and child temperament has been offered as a plausible explanation for such concordance. To assess whether temperament plays a role in the development of different attachment network configurations, in this preregistered individual participant data meta-analysis we tested the degree to which the temperament dimension of negative emotionality predicts the number of secure, insecure-avoidant, insecure-resistant, and disorganized attachment relationships a child has with mother and father. Data included in the linear mixed effects analyses were collected from seven studies sampling 872 children (49% female; 83% White). Negative emotionality significantly predicted the number of secure (d = -0.12) and insecure-resistant (d = 0.11), but not insecure-avoidant (d = 0.04) or disorganized (d = 0.08) attachment relationships. Nonpreregistered exploratory analyses indicated higher negative emotionality in children with insecure-resistant attachment relationships with both parents compared to those with one or none (d = 0.19), suggesting that temperament plays a small yet significant role in child-mother/child-father insecure-resistant attachment relationships concordance. Taken together, results from this study prompt a more in-depth examination of the mechanism underlying the small yet significantly higher chance that children with increased negative emotionality have for developing multiple insecure-resistant attachment relationships.

Examining mechanisms linking economic insecurity to interparental conflict among couples with low income.

Objective: The current study used the family stress model to test the mechanisms by which economic insecurity contributes to mothers' and fathers' mental health and couples' relationship functioning. Background: Although low household income has been a focus of poverty research, material hardship-defined as everyday challenges related to making ends meet including difficulties paying for housing, utilities, food, or medical care-is common among American families. Methods: Participants were from the Building Strong Families project. Couples were racially diverse (43.52% Black; 28.88% Latinx; 17.29% White; 10.31% Other) and living with low income (N = 2,794). Economic insecurity included income poverty and material hardship. Bayesian mediation analysis was employed, taking advantage of the prior evidence base of the family stress model. Results: Material hardship, but not income poverty, predicted higher levels of both maternal and paternal depressive symptoms. Only paternal depressive symptoms were linked with higher levels of destructive interparental conflict (i.e., moderate verbal aggression couples use that could be harmful to the partner relationship). Mediation analysis confirmed that material hardship operated primarily through paternal depressive symptoms in its association with destructive interparental conflict. Conclusion: The economic stress of meeting the daily material needs of the family sets the stage for parental mental health problems that carry over to destructive interparental conflict, especially through paternal depressive symptoms. Implications: Family-strengthening programs may want to consider interventions to address material hardship (e.g., comprehensive needs assessments, connections to community-based resources, parents' employment training) as part of their efforts to address parental mental health and couples' destructive conflict behaviors.

Will I love my second baby as much as my first? Prevalence and psychosocial correlates of maternal-fetal relationship anxiety for second-time mothers.

Most mothers have more than one child. Second-time mothers may worry about whether they will love the second baby as much as their first child. The current study examined mothers' maternal-fetal relationship anxiety (MFRA) to their second baby, the prediction of mother-infant bonding (MIB) and infant-mother attachment security post-partum, and the psychosocial correlates of mothers' MFRA during pregnancy. Mothers (N = 241, 85.9% White, 5.4% Black, 2.9% Asian/American, 3.7% Latina) and their second-born infants (55% boys) living in the Midwestern United States participated in a longitudinal investigation starting in the last trimester of pregnancy, and 1, 4, 8, and 12 months postpartum. Most women reported little to no anxiety about forming an attachment to their second baby (89.1%). MFRA predicted less maternal warmth toward the baby at 1, 4, and 8 months postpartum, but did not predict security of the infant-mother attachment at 12 months. Prenatal MFRA was also related to maternal depressive symptoms, an insecure attachment with the first child, more marital distress, and more adult attachment avoidance and ambivalence prenatally. Mothers worrying about loving a second baby as much as their first child may be experiencing other psychosocial risks that have repercussions for the developing mother-infant relationship.

La mayoría de las madres tiene más de un niño. Las que son madres por segunda vez se preocupan de si ellas amarán al segundo bebé tanto como al primer niño. El presente estudio examinó la ansiedad de la relación materno-fetal (MFRA) con su segundo bebé, la predicción del apego madre-infante y la seguridad de la afectividad madre-infante posterior al parto, así como las correlaciones sicosociales de la MFRA de las madres durante el embarazo. Las madres (N = 241, 85.9% blancas, 5.4% negras, 2.9 asiático-americanas, 3.7% latinas) y sus segundos infantes (55% varones), quienes vivían en el medio-oeste de los Estados Unidos, participaron en una investigación longitudinal comenzando en el último trimestre del embarazo, y a 1, 4, 8 y 12 meses después del parto. La mayoría de las mujeres reportó entre poca y ninguna ansiedad acerca de formar una relación afectiva con su segundo bebé (89.1%). La MFRA predijo menos calidez materna hacia el bebé a 1, 4 y 8 meses después del parto, pero no predijo la seguridad de la afectividad madre-infante a los 12 meses. La MFRA prenatal también se relacionó con los síntomas depresivos maternos, una afectividad insegura con el primer niño, más angustia marital, así como un mayor sentido adulto de ambivalencia y de evitar la afectividad prenatalmente. Las madres que se preocupan acerca de querer a su segundo bebé tanto como a su primer niño pudieran experimentar otros riesgos sicológicos y tener repercusiones para el desarrollo de la relación madre-infante.

La plupart des mères ont plus d'un seul enfant. Les mères pour la deuxième fois peuvent s'inquiéter si elles aimeront le second bébé autant que leur premier enfant. Cette étude a examiné l'anxiété de la relation maternelle-fœtale (abrégé MFRA selon l'anglais) des mères en lien à leur second bébé, la prédiction du lien mère-nourrisson et la sécurité de l'attachement nourrisson-mère postpartum ainsi que les corrélats psychosociaux de la MFRA des mères durant la grossesse. Les mères (N = 241, 85,9% blanches, 5,4% noires, 2,9% asiatiques américaines, 3,7% latinas) et leur deuxième bébé (55% de garçons) vivant dans le centre nord des Etats-Unis d'Amérique ont participé à une enquête longitudinale commençant le dernier trimestre de la grossesse et à 1, 4, 8 et 12 mois postpartum. La plupart des femmes ont fait état de presque aucune anxiété quant à la formation de l'attachement à leur second bébé (89,1%). La MFRA a prédit moins de chaleur maternelle envers le bébé à 1, 4, et 8 mois postpartum mais n'a pas prédit la sécurité de l'attachement bébé-mère à 12 mois. La MFRA prénatale était aussi liée aux symptômes dépressifs maternels, à un attachement insécure avec le premier enfant, à plus de détresse conjugale et à plus d'évitement et d'ambivalence de l'attachement adulte avant la naissance.

Paternal and maternal rejection and Chinese children's internalizing and externalizing problems across the transition to siblinghood: A developmental cascade model of family influence.

This longitudinal study examined the reciprocal associations between paternal and maternal rejection and firstborn children's (Mage  = 49.9 months; 55% boys) behavior problems across the transition to siblinghood in a sample of 120 families recruited from 2016 to 2018 from Shanghai, China. Parental rejection and behavior problems were assessed before (prenatal) and 1, 6, and 12 months after the birth of a baby sibling. Random intercept cross-lagged panel models revealed positive relations between internalizing problems and both maternal and paternal rejection, and between externalizing problems and paternal rejection at the between-person level (rs = .32-.37), but only cross-lagged effects from children's internalizing and externalizing problems to maternal rejection at the within-person level (ßs = .30-.54).

Changes in children's attachment security to mother and father after the birth of a sibling: Risk and resilience in the family.

Changes in children's attachment security to mother and father were examined for 230 firstborn children (M = 31.17 months), their mothers and fathers participating in a longitudinal investigation starting in the last trimester of the mothers' pregnancy and 1, 4, 8, and 12 months after the birth of an infant sibling. Both parents completed the Attachment Q-set at prenatal, 4, and 12 months. Growth mixture models revealed four latent classes in which children's attachments were (a) both secure with a modest decline to both parents (68.3%); (b) more secure with father than mother with a steep decline for both (12.6%); (c) both insecure with no change (10%); and (d) more secure with mother than father with a modest increase for both (9.1%). Multi-group latent growth curve analyses revealed that parenting and coparenting differed across families. Children had lower externalizing behavior problems in families with two secure attachments than in families with one secure attachment, either to mother or to father, who, in turn, had fewer problems than children with two insecure attachments. Findings underscore the strengths of a family systems framework to understand attachment relationships with multiple caregivers and the family risks and protective factors that covary with children's behavioral adjustment after the birth of a sibling.

Firstborn Children's Reactions to Mother-Doll Interaction Do Not Predict Their Jealousy of a Newborn Sibling: A Longitudinal Pilot Study.

Mothers are concerned about their firstborn children's acceptance of a baby sibling. Observing children's reactions to mothers interacting with an infant doll simulator has been offered as one means of seeing how children will react to the baby sibling. A longitudinal pilot study with 30 pregnant mothers and their firstborn children was conducted comparing children's behaviors to mother-doll interaction in the laboratory before birth with behaviors during home observations of mother-sibling interaction 1 month after birth. Children responded to mother-doll and mother-sibling interaction differently, with no significant associations across children's behaviors in mother-doll and mother-sibling interactions. The use of an infant doll simulator before birth did not reliably predict children's behavioral adjustment after the birth of a baby sibling.

Mother of One to Mother of Two: A Textual Analysis of Second-Time Mothers' Posts on the BabyCenter LLC Website.

Mothers use online resources frequently to obtain information on pregnancy, birth, and parenting. Yet, second-time mothers may have different concerns than first-time mothers given they have a newborn infant and another child at home. The current study conducted an on-line textual analysis of the posts of second-time mothers during pregnancy and the first months postpartum on the BabyCenter LLC website, one of the largest online parenting communities. Latent Dirichlet Allocation (LDA) analysis on roughly 16,000 posts to BabyCenter birth clubs in 2017 by approximately 4,000 users revealed second-time mothers relied on the online support of the BabyCenter community to share and discuss topics of pregnancy, birth, and child rearing. Second-time mothers also raised questions about preparing their firstborn children for a new baby sibling, how they would care for two children, whether they would love the second one as much as the first, and how the second child would change family dynamics. Future research needs to recognize that second-time mothers may have distinct concerns surrounding the birth of their second baby, and antenatal education and parenting classes may need to be modified to be more inclusive of these women's needs and perspectives. Online parenting communities offer avenues to support women as they make the transition from one child to two and may provide targeted opportunities to disseminate evidence-based practices that can assist these women and their children.

Amenders and Avoiders: an examination of guilt and shame for toddlers and their older siblings.

Guilt- and shame-prone responding were examined in a sample of 146, 18-month-old toddlers and their older siblings (M = 49.5 months, SD = 10.4) during mishap tasks which were used to differentiate both toddlers and their older siblings into Amenders (low avoidance) and Avoiders (high avoidance). Toddlers and older siblings classified as Amenders expressed more concern and were less distressed by the mishap than Avoiders. Children were divided into four groups: Amender-Amender (older sibling-toddler), Amender-Avoider, Avoider-Avoider, and Avoider-Amender to examine differences in sibling interaction and moral development. Older siblings in the Avoider-Avoider group were significantly more aggressive and less empathic toward toddlers than older siblings in the Avoider-Amender group. Toddlers in the Amender-Amender, Amender-Avoider, and Avoider-Amender groups showed significant gains in moral regulation from 18 to 24 months whereas toddlers in the Avoider-Avoider group did not. In contrast, while older siblings were generally high on moral regulation when toddlers were 18 months, this was not the case for older siblings in the Avoider-Avoider group, who had lower moral regulation scores that significantly increased over time. Findings are discussed with respect to the significance of sibling socialisation for toddlers' developing moral sensibility.

Growth in emotion understanding across early childhood: A cohort-sequential model of firstborn children across the transition to siblinghood.

Emotion understanding develops rapidly in early childhood. Firstborn children (N = 231, 55% girls/45% boys, 86% White, 5% Black, 3% Asian, 4% Latinx, Mage  = 29.92 months) were recruited into a longitudinal study from 2004 to 2008 in the United States and administered a series of tasks assessing eight components of young children's emotion understanding from ages 1 to 5. Cohort sequential analysis across three cohorts (1-, 2-, and 3-year-olds) demonstrated a progression of children's emotion understanding from basic emotion identification to an understanding of false-belief emotions, even after controlling for children's verbal ability. Emotion understanding scores were related to children's theory of mind and parent reports of empathy, but not emotional reactivity, providing evidence of both convergent and discriminant validity.

Material Hardship in Families With Low Income: Positive Effects of Coparenting on Fathers' and Mothers' Parenting and Children's Prosocial Behaviors.

Families with low income experience high levels of economic insecurity, but less is known about how mothers and fathers in such families successfully navigate coparenting and parenting in the context of material hardship. The current study utilized a risk and resilience framework to investigate the underlying family processes linking material hardship and children's prosocial behaviors in a sample of socioeconomically disadvantaged mother-father families with preschoolers from the Building Strong Families project (N = 452). Coparenting alliance and mothers' and fathers' responsive parenting were examined as mediators. Results of structural equation modeling showed that coparenting alliance was associated with higher levels of both mothers' and fathers' responsive parenting. Subsequently, both parents' responsive parenting were associated with higher levels of children's prosocial behaviors. Material hardship was not associated with coparenting alliance and either parent's responsive parenting. Tests of indirect effects confirmed that the effects of coparenting alliance on children's prosocial behaviors were mediated through both mothers' and fathers' responsive parenting. Overall, these results suggest that when mothers and fathers have a strong coparenting alliance, they are likely to withstand the negative effects of material hardship and thus engage in positive parenting behaviors that benefit their children's prosocial development. Family strengthening interventions, including responsible fatherhood programs, would do well to integrate a strong focus on enhancing a positive coparenting alliance between mothers and fathers.

A systematic review of human paternal oxytocin: Insights into the methodology and what we know so far.

With the consolidation of fathers' engagement in caregiving, understanding the neuroendocrine and hormonal mechanisms underlying fatherhood becomes a relevant topic. Oxytocin (OT) has been linked with maternal bonding and caregiving, but less is known about the role of OT in human fatherhood and paternal caregiving. A systematic review of methods and findings of previous OT research in human fathers was carried. The literature search on PubMed and Scopus yielded 133 records. Twenty-four studies were included and analyzed. Significant variability emerged in OT methodology, including laboratory tasks, assessment methods, and outcome measures. Fathers' OT levels appear to increase after childbirth. OT was significantly correlated with less hostility and with the quality of paternal physical stimulation in play interactions, but not with paternal sensitivity. Fathers' and children's OT levels were significantly correlated in a limited subset of studies, intriguingly suggesting that cross-generational OT regulation may occur during the early years of life. This study highlights relevant issues and limitations of peripheral OT assessment in human subjects, especially in fathers. Although the study of paternal neuroendocrinology appears promising, coping with these issues requires dedicated efforts and methodological suggestions are provided to guide future advances in this field.

Adrenocortical interdependence in father-infant and mother-infant dyads: Attunement or something more?

Father-infant and mother-infant (one-year-olds) adrenocortical attunement was explored during the Strange Situation Procedure (SSP) among 125 father-infant and 141 mother-infant dyads. Cortisol was assessed at baseline (T1), 20 (T2), and 40 minutes (T3) after the first parent-infant separation. Initial correlations indicated significant associations between father-infant and mother-infant cortisol at each time. Cortisol interdependence was further explored using Actor-Partner Interdependence Models. There was no evidence supporting cortisol interdependence based on within-time residual correlations between parent-infant cortisol, once stability and cross-lagged paths were controlled. Infant cortisol at T2 predicted T3 cortisol for fathers and mothers resulting in a series of follow-up exploratory analyses to examine mediating processes which revealed that infant distress during the SSP predicted infant T2 cortisol, which, in turn, predicted infant negativity during the 15-min mother-infant teaching task that followed the SSP. Among father-infant dyads, infant T2 cortisol predicted infant negativity during father-infant interaction, with infants expressing more negativity having less sensitive fathers. Findings provide little support of parent-infant adrenocortical attunement across either father-infant or mother-infant dyads during the SSP, but preliminary evidence indicates infant distress as a potential mediator. Future research may want to focus on affective and behavioral processes that underlie the concept of parent-infant adrenocortical attunement.

Configurations of mother-child and father-child attachment as predictors of internalizing and externalizing behavioral problems: An individual participant data (IPD) meta-analysis.

An unsettled question in attachment theory and research is the extent to which children's attachment patterns with mothers and fathers jointly predict developmental outcomes. In this study, we used individual participant data (IPD) meta-analysis to assess whether early attachment networks with mothers and fathers are associated with children's internalizing and externalizing behavioral problems. Following a pre-registered protocol, data from 9 studies and 1,097 children (mean age: 28.67 months) with attachment classifications to both mothers and fathers were included in analyses. We used a linear mixed effects analysis to assess differences in children's internalizing and externalizing behavioral problems as assessed via the average of both maternal and paternal reports based on whether children had two, one, or no insecure (or disorganized) attachments. Results indicated that children with an insecure attachment relationship with one or both parents were at higher risk for elevated internalizing behavioral problems compared with children who were securely attached to both parents. Children whose attachment relationships with both parents were classified as disorganized had more externalizing behavioral problems compared to children with either one or no disorganized attachment relationship with their parents. Across attachment classification networks and behavioral problems, findings suggest (a) an increased vulnerability to behavioral problems when children have insecure or disorganized attachment to both parents, and (b) that mother-child and father-child attachment relationships may not differ in the roles they play in children's development of internalizing and externalizing behavioral problems.

Don't touch: Developmental trajectories of toddlers' behavioral regulation related to older siblings' behaviors and parental discipline.

Behavioral regulation is one of the key developmental skills children acquire during early childhood. Previous research has focused primarily on the role of parents as socializing agents in this process, yet it is likely that older siblings also are influential given the numerous daily interactions between siblings. This exploratory longitudinal study investigated developmental heterogeneity in behavioral regulation during toddlerhood and the early preschool years (18 to 36 months) and relations with older siblings' control and behavioral regulation while taking into account parental discipline. Toddlers were visited at home at 18, 24, and 36 months and observed during a gift-delay task with their older sibling in 93 families. Behavioral regulation of both siblings and gentle and harsh control of the older sibling were coded during the sibling gift-delay task, which was validated using parent-reports of toddlers' internalized conduct. Analyses revealed five distinct developmental trajectories among toddlers' behavioral regulation, revealing different patterns of developmental multifinality and equifinality. Older siblings' harsh control and parental discipline differed across toddler trajectory groups. Older siblings' behaviors covaried with the toddlers' behavioral regulation suggesting that older siblings may be acting as models for younger siblings, as well as disciplining and teaching toddlers to resist temptation.

More than meets the eye: The neural development of emotion face processing during infancy.

This study explored the impact of infant temperament and maternal stress on the development of the infant medial prefrontal cortex (mPFC) among sixteen 6-8-month-old infants. Functional Near Infrared Spectroscopy (fNIRS) was used to measure activation of the infant mPFC in response to angry, happy, and sad faces. Infant temperament and dimensions of maternal stress were measured with the Infant Behavior Questionnaire and the Parenting Stress Index Respectively. Infants with high negative emotionality demonstrated increased mPFC activation in association with all emotion face conditions. Negative emotionality moderated the effect of total maternal stress on mPFC activation to angry and sad faces. Mother-infant dysfunctional interaction was related to increased mPFC activation associated with happy faces, supporting the "novelty hypothesis", in which the mPFC responds more strongly to unique experiences. Therefore, this study provides additional evidence that infant temperament and the quality of the mother-infant relationship influence the development of the mPFC and how infants process emotions.

Widening the lens on family processes and the development of parent-child attachment relationships.

This commentary addresses the research conducted by McConnachie et al. (this issue) on attachment in gay father families, lesbian mother families, and heterosexual parent families. Strengths of the research included the inclusion of different family constellations, the focus on between-family and within-family differences, the longitudinal research design, and the age-appropriate assessment of attachment. Some limitations noted included the lack of control for age at adoption in analyses, the lack of information on parenting processes and parental mental health in the formation of attachment, and questions about information obtained from parent reports of children's prior caregiving histories.

What are the Marital Problems of Happy Couples? A Multimethod, Two-Sample Investigation.

How couples handle marital conflict may depend on what issues they are facing, as some issues may be more difficult to resolve than others. What is unclear, however, is what issues happy couples face and how these issues may be different for couples depending on their developmental stage. To explore this possibility, the current study used both self-reports and observations drawn from two separate samples of happily married couples-one early in middle adulthood (N = 57 couples; average marital duration = 9 years) and one in older adulthood (N = 64 couples; average marital duration = 42 years). Results indicated that all issues were relatively minor, but early middle-aged couples reported more significant problems than did older couples. As to determining the most salient topic for happy couples, it depended on the spouses' gender, developmental stage, and how salience was assessed (i.e., highest rated issue vs. most discussed issue). Only moderate links were found between what happy couples said was their most serious concern and what they actually tried to resolve during observations of marital problem-solving, but there were differences in how spouses behaved based on the proportion of their time discussing certain topics. Findings suggest that more attention should be devoted to understanding what marital issues happy couples discuss and why, as doing so may reveal how couples maintain their marital happiness.

Las maneras en las que las parejas manejan el conflicto conyugal puede depender de qué problemas enfrentan, ya que algunos problemas pueden ser más difíciles de resolver que otros. Sin embargo, lo que no está claro es qué problemas enfrentan las parejas felices y cómo estos pueden ser diferentes para las parejas según su etapa de desarrollo. Para analizar esta posibilidad, el presente estudio utilizó autoinformes y observaciones tomados de dos muestras distintas de parejas felizmente casadas: una a principios de la mediana edad (N = 57 parejas; duración conyugal promedio = 9 años) y una en la tercera edad (N = 64 parejas; duración conyugal promedio = 42 años). Los resultados indicaron que todos los problemas fueron relativamente menores, pero las parejas de principios de la mediana edad informaron problemas más importantes que las parejas mayores. En cuanto a la determinación del problema más prominente para las parejas felices, dependió del género de los cónyuges, la etapa de desarrollo y cómo se evaluó la prominencia (p. ej.: el problema más puntuado frente al problema más debatido). Solo se hallaron vínculos moderados entre lo que las parejas felices declararon como su mayor preocupación y lo que en realidad intentaron resolver durante las observaciones de la resolución de problemas conyugales, pero hubo diferencias en las maneras en las que los cónyuges se comportaron según la proporción de su tiempo debatiendo ciertos temas. Los resultados sugieren que debería dedicarse más atención a comprender qué problemas conyugales debaten las parejas felices y por qué, ya que hacerlo puede revelar cómo las parejas mantienen su felicidad conyugal.

Development of externalizing symptoms across the toddler period: The critical role of older siblings.

We examined child and family risk factors that were associated with the development of individual differences in externalizing problems across the toddler years. Our central hypothesis was that toddlers with more aggressive and disruptive older siblings would be at elevated risk for heightened levels of externalizing behavior. We tested this hypothesis in the context of other theoretically relevant risk factors: toddlers' inhibitory and internalized control, experiences of coercive parental discipline, and gender. Participants were 167 toddlers, their older siblings, and parents in a longitudinal study following younger siblings across the first 3 years of life. Mothers and fathers contributed ratings of externalizing symptoms between 1 and 18 months across the transition to siblinghood for older siblings and 18 to 36 months for younger siblings. Toddlers' inhibitory and internalized control were assessed using behavioral and parent report measures, and parents completed questionnaires concerning their use of coercive discipline. Individual differences in toddler externalizing symptoms were highly stable between 18 and 36 months of age for a sample of second-born children with older siblings, even though there was evidence of significant decline in externalizing symptoms from 18 to 36 months. As predicted, toddlers with elevated levels of externalizing symptoms tended to have older siblings with higher externalizing difficulties across the first 18 months of the younger sibling's life. Thus, these findings highlighted the need for further research on older siblings' contributions to the behavioral development of their toddler-age younger siblings.

Longitudinal relations between coparenting and father engagement in low-income residential and nonresidential father families.

Coparenting relationship quality and father involvement are closely linked but few studies have investigated this relationship using samples of socioeconomically disadvantaged families. The current study used family systems theory to examine the longitudinal and bidirectional relations between coparenting relationship quality and father engagement in caregiving and play, using a large and racially diverse sample of low-income residential and nonresidential fathers in the Building Strong Families project (N = 1,908). Structural equation modeling tested cross-lagged relations between couple-level coparenting and father engagement at two time points for both residential and nonresidential father families. For residential fathers, positive coparenting at 15 months predicted father engagement in caregiving at 36 months. There was no support for a bidirectional or unidirectional model between coparenting and father engagement in play for either residential or nonresidential fathers. There were significant concurrent relations between coparenting and father engagement in caregiving and play for both residential and nonresidential fathers, providing support for positive spillover in line with family systems theory.
