Pregnancy and early motherhood involve uncertainty and change, which can evoke mental health problems. We identified maternal mental health trajectories in pre-and postnatal period, and examined their association with later child mental health and development. Finnish mothers reported psychological distress (General Health Questionnaire ) and depressive (Beck Depression Inventory ) symptoms in pregnancy (T1; N ¼ 788) and two months (T2; N ¼ 657) and 12 months (T3; N ¼ 545) postpartum. Both parents accounted their child's mental health (Behavior Assessment System for Children [BASC]) and social (Social Skills Rating System [SSRS], Child Behavior Scale [CBS]) and cognitive development (Five to Fifteen [FTF]) when the child was 7-8 years old (T4; N ¼ 485). We identified five trajectories depicting unique timing and course of maternal mental health from pregnancy into 1 year of mothering: Stable low levels of mental health symptoms (75%) and prenatal (6%), early postpartum (9%) and late postpartum (6%) mental health problems. The fifth trajectory, heterogeneous high levels of mental health problems (4%) was an unclassified post hoc class, combining mothers with chronic high or highly variable mental health profiles. Results show some trajectory-related timing effects on children's mental health and cognitive development. The trajectories of early postpartum and heterogeneous high levels of mental health problems predicted higher level of internalizing symptoms as compared to stable low-levels trajectory. The heterogeneous highlevels trajectory predicted higher levels of problems in executive functions than the stable low and late postpartum trajectories, and in memory tasks than children in other trajectories. We discuss the timing and course of maternal mental health from the viewpoint of infant and child development.

Family systems reorganize during transitional periods, such as the birth of a new child. Longitudinal research, however, on family dynamics during the transition to parenthood is lacking. Accordingly, the authors aimed to identify family system trajectories from pregnancy to the child's first birthday and to examine their contextual predictors. Both parents (N = 702) reported autonomy and intimacy in marital (wife‐to‐husband, husband‐to‐wife) and parenting (mother‐to‐child, father‐to‐child) relations during pregnancy and at child's ages of 2 months and 12 months. Finite mixture modeling revealed 7 unique family system trajectories: (a) Cohesive (35%), (b) Disengaged (5%), (c) Enmeshed Declining (6%), (d) Enmeshed Quadratic (5%), (e) Authoritarian (14%), (f) Escalating Crisis (4%), and (g) Discrepant (15%) families. Parental education in interaction with duration of partnership and parity predicted family trajectory membership. The study demonstrates how different family types reorganize during the transition to parenthood; this includes decline, growth, and stability in autonomy and intimacy.

Abstract:The family environment shapes children's social information processing and emotion regulation. Yet, the long-term effects of early family systems have rarely been studied. This study investigated how family system types predict children's attentional biases toward facial expressions at the age of 10 years. The participants were 79 children from Cohesive, Disengaged, Enmeshed, and Authoritarian family types based on marital and parental relationship trajectories from pregnancy to the age of 12 months. A dotprobe task was used to assess children's emotional attention biases toward threatening (angry) and affiliative (happy) faces at the early (500 ms) and late (1250 ms) stages of processing. Situational priming was applied to activate children's sense of danger or safety. Results showed that children from Cohesive families had an early-stage attentional bias toward threat, whereas children from Enmeshed families had a late-stage bias toward threat. Children from Disengaged families had an early-stage attentional bias toward threat, but showed in addition a late-stage bias away from emotional faces (i.e., both angry and happy). Children from Authoritarian families, in turn, showed a late-stage attentional bias toward emotional faces. Situational priming did not moderate the effects of family system types on children's attentional biases. The findings confirm the influence of early family systems on the attentional biases, suggesting differences in the emotion regulation strategies children have developed to adapt to their family environments.http://mc.manuscriptcentral.com/ijbd International Journal of Behavioral Development regulation.

Research has demonstrated the importance of early family characteristics, such as the quality of caregiving, on children's later mental health. Information is, however, needed about the role of more holistic family systems and specific child-related socioemotional mechanisms.In this study, we conceptualize families as dynamic family system types, consisting of both marital and parenting trajectories over the transition to parenthood. First, we examine how early family system types predict children's anxiety, depression, peer exclusion and emotion regulation. Second, we test whether couple's infertility history and other family-related contextual factors moderate the effects of family system types on child outcomes. Third, we test whether children's emotion regulation and peer exclusion mediate the effects of family system types on anxiety and depression. The participants were 452 families representing cohesive, distant, authoritative, enmeshed, and discrepant family types, identified on the basis of relationship autonomy and intimacy from pregnancy to the child's age of 2 and 12 months.Children's anxiety, depression, emotion regulation, and peer exclusion were assessed at the age of 7-8 years. Structural equation modeling showed that distant, enmeshed, and discrepant families similarly predicted children's heightened anxiety and depression. Infertility history, parental education, and parity moderated the associations between certain family system types and child outcomes. Finally, emotion regulation, but not peer exclusion, was a common mediating mechanism between distant and enmeshed families and children's depression. The results emphasize the importance of early family environments on children's emotion regulation development and internalizing psychopathology.Keywords: anxiety; depression; emotion regulation; emotional problems; family relationships; infancy; infertility; peer exclusion; trajectories; transition to parenthood 3 Running head: PATHWAYS FROM EARLY FAMILY TYPES TO INTERNALIZING Child development fundamentally takes place within family relationships. Both parentchild and interparental interactions shape how children express and regulate their emotions (Morris, Silk, Steinberg, Myers, & Robinson, 2007) and relate to self and others (Davies & Martin, 2013). Early developmental alterations in these socioemotional processes can heighten the risk for emotional problems in later life (Brumariu & Kerns, 2010). Indeed, there is some evidence about the mediating role of emotion regulation and peer relationships between early family experiences and children's later internalizing symptoms (e.g., Kim & Cicchetti, 2010). Further, families interact with a number of contextual factors. In the current study, half of the participating couples had infertility history. Involuntary infertility can influence both family dynamics and children's vulnerability to family dysfunctions (Barnes et al., 2004). However, it is not yet well understood how family system types and contextual factors shape children's...
