This longitudinal randomized controlled trial examined the impact of a doula home visiting intervention for young, low-income mothers on parenting and toddler social-emotional development and tested whether intervention effects were moderated by maternal emotional and behavioral health characteristics. 156 mothers were offered home visits from a home visitor starting in mid-pregnancy through several years postpartum, with a community doula also working with the mother during pregnancy and after the birth. 156 received case management. Interviews, video recordings of mother-child interactions, and toddler assessments were conducted at 3 weeks, 3 months, 13 months, and 30 months of age. Intent-to-treat analyses conducted with the full sample showed some intervention effects. Moderation analyses, however, showed that most effects were concentrated among mothers engaged in high levels of risk-taking (delinquent behaviors, school suspensions, smoking, alcohol use, sexual risk-taking). Among higher risk-taking mothers, the intervention was related to less intrusiveness during early infancy, less psychological and physical aggression during toddlerhood, more sensitive parenting attitudes, and greater toddler social relatedness. Maternal depressive symptoms were only a moderator for toddler behavior problems. These findings suggest that doula home visiting may be a particularly effective model for enhancing sensitive, non-aggressive parenting among young mothers with a history of risk-taking behavior.

The DNA revolution has energized research on interactions between genes and environments (GxE) by creating indices of G (polygenic scores) that are powerful predictors of behavioral traits. Here, we test the extent to which polygenic scores for attention-deficit/hyperactivity disorder and neuroticism moderate associations between parent reports of their children’s environmental risk (E) at ages 3 and 4 and teacher ratings of behavior problems (hyperactivity/inattention, conduct problems, emotional symptoms, and peer relationship problems) at ages 7, 9 and 12. The sampling frame included up to 6687 twins from the Twins Early Development Study. Our analyses focused on relative effect sizes of G, E and GxE in predicting behavior problems. G, E and GxE predicted up to 2%, 2% and 0.4%, respectively, of the variance in externalizing behavior problems (hyperactivity/inattention and conduct problems) across ages 7, 9 and 12, with no clear developmental trends. G and E predictions of emotional symptoms and peer relationship problems were weaker. A quarter (12 of 48) of our tests of GxE were nominally significant (p = .05). Increasing the predictive power of G and E would enhance the search for GxE.

Some children are more affected by specific family environments than others, as a function of differences in their genetic make-up. However, longitudinal studies of genetic moderation of parenting effects during early childhood have not been conducted. We examined developmental profiles of child behavior problems between 18 months and age 8 in a longitudinal parent–offspring sample of 361 adopted children. In toddlerhood (18 months), observed structured parenting indexed parental guidance in service of task goals. Biological parent psychopathology served as an index of genetic influences on children’s behavior problems. Four profiles of child behavior problems were identified: low stable (11%), average stable (50%), higher stable (29%), and high increasing (11%). A multinominal logistic regression analysis indicated a genetically moderated effect of structured parenting, such that for children whose biological mother had higher psychopathology, the odds of the child being in the low stable group increased as structured parenting increased. Conversely, for children whose biological mother had lower psychopathology, the odds of being in the low stable group was reduced when structured parenting increased. Results suggest that increasing structured parenting is an effective strategy for children at higher genetic risk for psychopathology, but may be detrimental for those at lower genetic risk.

Childhood exposure to intimate partner violence (IPV) can have lasting effects on well-being. Children also display resilience following IPV exposure. Yet, little research has prospectively followed changes in both maladaptive and adaptive outcomes in children who experience IPV in early life. The goal of the current study was to investigate how child factors (irritability), trauma history (severity of IPV exposure), maternal factors (mental health, parenting), and early intervention relate to trajectories of behavior problems (internalizing and externalizing problems) and resilience (prosocial behavior, emotion regulation), over 8 years. One hundred twenty mother-child dyads participated in a community-based randomized controlled trial of an intervention for IPV-exposed children and their mothers. Families completed follow-up assessments 6–8 months (N = 71) and 6–8 years (N = 68) later. Although intention-to-treat analyses did not reveal significant intervention effects, per-protocol analyses suggested that participants receiving an effective dose (eight sessions) of the treatment had fewer internalizing problems over time. Child irritability and maternal parenting were associated with both behavior problems and resilience. Maternal mental health was uniquely associated with child behavior problems, whereas maternal positive parenting was uniquely associated with child resilience. Results support the need for a dyadic perspective on child adjustment following IPV exposure.

Maternal depressive symptoms (MDS) have been linked to both child internalizing and externalizing behavior problems. Theory suggests that child attachment security may be a protective factor against the negative effects of MDS. This study examined child attachment security as a buffer of the link between MDS and child internalizing and externalizing behavior problems at two time points in a predominantly African American sample. Participants included mothers (N = 164; M age = 29.68 years; 76% African American) and their preschool-aged children (60% girls; M age = 44.67 months) recruited from four Head Start centers in low-income neighborhoods in Baltimore, Maryland. MDS were concurrently associated with child internalizing and externalizing behavior problems at both time points. No significant main effects of child attachment security on behavior problems emerged; however, child attachment moderated the association between MDS and child internalizing behavior problems at Time 2, such that MDS predicted greater child internalizing problems when attachment security was low, and the effect was attenuated when attachment security was high. No interaction emerged for child externalizing problems. Findings suggest that secure attachment in early childhood can serve as a protective factor in the context of parental risk. We discuss implications for intervention and the intergenerational transmission of psychopathology.

Families of youth with autism spectrum disorder (ASD) are vulnerable to maladaptive psychosocial experiences, including elevated youth emotional and behavioral problems (EBPs) and poor parent couple relationship outcomes. Yet, the extent to which these family psychosocial experiences are intertwined has been given little research attention. The present study longitudinally investigated the bidirectional associations between parent couple conflict (PCC) and youth EBPs in 188 families of children and adolescents with ASD (initially aged 5 to 12 years) across four time points (T1, T2, T3, T4), each spaced 12 months apart. Mother- and father-report of youth EBPs and PCC were entered into a cross-lagged panel model. After adjusting for youth age and intellectual disability status and parent education and couple relationship length, the results indicated that father-report of PCC predicted increased youth EBPs 12 months later (T1→T2 and T2→T3). In addition, father-report of youth EBPs predicted increased PCC 12 months later (T3→T4). Mother-report did not demonstrate cross-lagged effects. The findings suggest that fathers’ perceptions of PCC and youth emotional and behavioral functioning are transactionally related, highlighting the need for family-wide interventions.

The current study assessed whether the proportion of childhood (age 0–9 years) in poverty altered the developmental trajectories (ages 9–24) of multimethodological indicators of psychological well-being. In addition, we tested whether exposure to cumulative risk over time mediated the association between poverty exposure and psychological well-being. Measures of psychological well-being included internalizing and externalizing symptoms, a behavioral index of learned helplessness (task persistence), and chronic physiological stress (allostatic load). Exposure to poverty during childhood predicted the trajectory of each development outcome: individuals with more poverty exposure during childhood showed (a) relatively high levels of internalizing symptoms that diminished more slowly with maturation, (b) relatively high levels of externalizing symptoms that increased faster over time, (c) less task persistence indicative of greater learned helplessness, and (d) higher levels of chronic physiological stress which increased faster over time relative to persons with less childhood poverty exposure. Trajectories of cumulative risk exposure from physical and psychosocial surroundings from 9–24 years accounted for the association between childhood poverty and the growth curves of internalizing and externalizing symptoms but not for learned helplessness or chronic physiological stress. Additional sensitivity analyses indicate that early childhood disadvantage is particularly problematic for each outcome, except for internalizing symptoms which seem sensitive to the combination of early and lifetime poverty exposure. We also explored whether domains of cumulative risk as well as two alternatives, maternal sensitivity or family cohesion, functioned as mediators. Little evidence emerged for any of these alternative mediating constructs.

Motivated by Edward Zigler's proposition that programs serving children (birth through 12 years) can have long-term effects on well-being and development, we used data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (N = 1,258) to test two pathways by which early care and education (ECE) are linked to after-school organized activities in middle childhood and to problem behaviors in late adolescence and adulthood. In support of an activities pathway, we found children with more ECE hours and more epochs in center-based ECE settings from 1 to 54 months had more epochs in after-school organized activities from kindergarten to 5th grade, which then predicted less impulsivity and less police contact at age 26. In support of a child pathway, we found that more ECE hours and more epochs in center-based ECE settings were linked to externalizing problems in early childhood, which then predicted higher problem behaviors in middle childhood, late adolescence, and adulthood. Together, these pathways underscored the potential of direct and indirect links of ECE and after-school organized activities in relation to later development.

The aim of this study is to examine the association between maternal adverse childhood experiences (ACEs) and mental health problems in adolescent offspring. Data were obtained from the population-based Kochi Child Health Impact of Living Difficulty (K-CHILD) study in 2016, and participants were 10,810 children in the fifth grade (3,144 pairs), eighth grade (3,497 pairs), and eleventh grade (4,169 pairs) living in Kochi Prefecture, Japan. Mothers of participating children were asked about their ACEs, childhood social economic status, current mental and physical health, current social economic status, positive parenting behaviors, child maltreatment, marital status, and child behavior problems using the Strength and Difficulty Questionnaire. Children reported their depressive symptoms using the Depression Self-Rating Scale. Children of mothers with a larger number of ACEs showed higher levels of behavior problems (p for trend <.001) and depressive symptoms (p for trend <.001), adjusting for potential confounders. In particular, maternal psychological distress mediated the association between maternal ACEs and child mental health. The adverse effects of maternal ACEs may have a direct intergenerational impact on behavior problems and depressive symptoms in adolescent offspring. Further studies to elucidate possible mediators are needed.

Mapuche represents the largest indigenous group in Chile amounting to nearly 10% of the total population. In a longitudinal cohort of 12,398 children, we analyzed the role of ethnicity in physical and psychosocial development of Mapuche and nonindigenous Chilean toddlers (age 2.5 years), taking into account sociodemographic and caregiver characteristics. As indicated by our univariate analysis, the Mapuche developmental niche was characterized by lower income, lower maternal education, poorer quality of the home environment, longer breastfeeding, and higher parental stress. Physical development showed higher body mass index. Mapuche children showed less externalizing problems. We then analyzed the incremental contribution of ethnicity in a series of hierarchical regressions with the second wave of developmental measurements (age 4.5 years) as outcome variables, showing a significant but modest incremental contribution of ethnicity to the prediction of children's development between 2.5 and 4.5 years of age. Controlling for environmental variables, Mapuche showed less externalizing and internalizing, behavior problems. Socioeconomic status, quality of the home environment, and parenting stress were stronger predictors of socioemotional development than ethnicity per se.

According to the developmental psychopathology framework, adverse childhood experiences, including child sexual abuse (CSA), may alter the course of normal development in children. Attachment security has been identified as a protective factor against psychopathology and may thus play a critical role in predicting victims’ adaptation. The main objective of the present study was to investigate the mediating effect of attachment representations in the relation between CSA and behavior problems over a 1-year period. The sample consisted of 391 children (251 sexually abused) aged 3.5 to 6 years. The Attachment Story Completion Task and the Child Behavior Checklist were used. Disorganized attachment partially mediated the relation between CSA and children's internalizing and externalizing behavior problems 1 year following the initial assessment. This mediation effect was not found for ambivalent nor secure attachment dimensions. Child gender was found to moderate the association between CSA and disorganization, with larger effects of CSA among boys. These findings underscore the importance of considering attachment representations in treatment programs for preschool victims. Evidence-based practice focusing on trauma could be combined with an attachment-based intervention targeting the parent–child relationship. Moreover, interventions should be gender sensitive, as CSA appears to affect boys and girls differently.

The purpose of the present study was to examine the temperament and behavior problems of 32 toddlers born preterm and very low birth weight and 25 toddlers born full-term without medical problems. Mothers completed the Early Childhood Behavior Questionnaire and the Child Behavior Checklist-1.5–5 for assessing toddler`s temperament and behavior problems, respectively. The results showed that, regarding temperament, toddlers born preterm exhibited higher scores on the temperament dimensions Motor Activation, Perceptual Sensitivity, and High Intensity Pleasure, and lower scores on the temperament dimension Cuddliness than toddlers born full-term. In regard to behavior problems, toddlers born preterm showed higher attention problems scores than the comparison group. These findings indicated that children born preterm presented developmental vulnerabilities in temperament dimensions related to behavior problems at toddlerhood. Early intervention programs for preventing psychological problems in at-risk children, especially those born preterm, could focus on children’s temperament dispositions.

The aim of this short term longitudinal study, based on the system theory, was to test the association between different aspects of family functioning of preschoolers and their socioaffective competencies at the end of the first grade. The total sample included 278 children (137 boys and 141 girls) and their families. The analysis of variance results regarding the aspects of family cohesion and harmony showed that preschoolers from more cohesive families display more social skills, while those from more conflicting families display more externalizing behavior problems (aggression and irritability). With respect to the family's ability to resolve problems, it was observed that, especially for middle and upper class families, this aspect is associated with better social skills and fewer internalized behavior problems. Overall, results of the present study suggest that the family functioning at early stage might influence children's abilities to regulate their emotions and to establish/maintain important relationships with peers and teachers in their early school years.

Background: Behavioral and psychological symptoms of dementia (BPSDs) are routinely cited as important predictors of caregiver burden and depression. Although BPSDs include a wide variety of patient behaviors, they are routinely grouped together as one construct to differentiate them from cognitive symptoms of dementia. Determining the specific BPSDs that result in increased depression and burden for caregivers may elucidate the stress process for caregivers and facilitate the development of effective interventions for caregivers.

Methods: We conducted a systematic review of English-language articles published from 1990 to 2010 to determine whether there are known symptoms or symptom clusters which exert undue negative impact on caregiver depression and burden. Additionally, we review systems used for classifying BSPD symptom clusters and determine whether there have been any mechanisms studied by which individual BPSD symptoms negatively affect caregivers. Finally, we examine how the role of timing of symptoms has been examined within the literature.

Results: Thirty-five original research articles examined the impact of an individual behavior symptom on caregiver burden or depression/depressive symptoms. The studies had no consistent system for categorizing symptoms. Although depression, aggression, and sleep disturbances were the most frequently identified patient symptoms to impact negatively on caregivers, a wide range of symptoms was associated with caregiver burden and depression.

Conclusions: The evidence is not conclusive as to whether some symptoms are more important than others. The studies reviewed were largely exploratory relative to the differential impact of individual BPSDs and did not focus on testing causal mechanisms by which specific symptoms exert more impact on caregiver mental health than others. Future research may benefit from the re-conceptualization of BPSDs from the perspective of their impact on the caregiver to examine hypothesis-driven differences among BPSD symptom clusters.

Research has consistently shown that religiousness is associated with lower levels of alcohol and drug use, but little is known about the nature of adolescent religiousness or the mechanisms through which it influences problem behavior in this age group. This paper presents preliminary results from the Mid-Atlantic School Age Twin Study, a prospective, population-based study of 6–18-year-old twins and their mothers. Factor analysis of a scale developed to characterize adolescent religiousness, the Religious Attitudes and Practices Inventory (RAPI), revealed three factors: theism, religious/spiritual practices, and peer religiousness. Twin correlations and univariate behavior-genetic models for these factors and a measure of belief that drug use is sinful reveal in 357 twin pairs that common environmental factors significantly influence these traits, but a minor influence of genetic factors could not be discounted. Correlations between the multiple factors of adolescent religiousness and substance use, comorbid problem behavior, mood disorders, and selected risk factors for substance involvement are also presented. Structural equation modeling illustrates that specific religious beliefs about the sinfulness of drugs and level of peer religiousness mediate the relationship between theistic beliefs and religious/spiritual practices on substance use. Limitations and future analyses are discussed.

We examine the impact of rearing by an alcoholic parent on risk for child behavior problems using data on 2492 offspring drawn from two ongoing studies of children of female and male same- and opposite-sex twin pairs. Results of regression models predicting child behavior problems from parent and co-twin lifetime history of alcohol use disorder (AUD) provide support for genetic but not environmental transmission of externalizing and a measure of total problem behaviors. Results for internalizing behavior were inconclusive with respect to transmission of risk.

In the mid to late 1980s a major controversy erupted when Belsky's (1986, 1988, 1990) analysis of research produced the conclusion that early and extensive nonmaternal care carried risks in terms of increasing the probability of insecure infant–parent attachment relationships and promoting aggression and noncompliance during the toddler, preschool, and early primary school years. Widespread critiques of Belsky's analysis called attention to problems associated with the Strange Situation procedure for measuring attachment security in the case of day-care reared children and to the failure of much of the cited research to take into consideration child-care quality and control for background factors likely to make children with varying child-care experiences developmentally different in the first place. In this lecture, research concerning the developmental effects of child care and maternal employment initiated in the first year of life that has emerged since the controversy broke is reviewed. Evidence indicating that early, extensive, and continuous nonmaternal care is associated with less harmonious parent–child relations and elevated levels of aggression and noncompliance suggests that concerns raised about early and extensive child care 15 years ago remain valid and that alternative explanations of Belsky's originally controversial conclusion do not account for seemingly adverse effects of routine nonmaternal care that continue to be reported in the literature.
