Description
Using a sample of children from divorced homes, the current study assesses the effects of family relationship variables on romantic outcomes in young adulthood, through the influence of several individual-level variables. In particular, children's coping efficacy and peer competence are examined as mediators of the effects of parenting and interparental conflict on children's later romantic involvement and relationship quality. Assessments occurred during childhood, when children were between the ages of nine and 12, in adolescence, when children were ages 15 to 18, and in young adulthood, when children were ages 24 to 27, spanning a period of 15 years. Childhood and adolescent variables were measured using child- and mother-report data and young adult measures were completed by the young adults and their romantic partners. One model was tested using all participants in the sample, regardless of whether they were romantically involved in young adulthood, and revealed that maternal warmth in childhood was linked with children's coping efficacy six years later, which was marginally related to an increased likelihood of being romantically involved and to decreased romantic attachment at the 15-year follow-up. A model with only the participants who were romantically involved in young adulthood also revealed a link between childhood maternal warmth and coping efficacy in adolescence, which was then marginally related to increased romantic satisfaction and to confidence in the romantic relationship in young adulthood. Marginal mediation was also found for several of the proposed paths, and there was little evidence to support path differences between males and females. Implications of the present findings for research with children from divorced families and the development of preventive interventions are discussed. In particular, parenting, interparental conflict, peer competence, and coping efficacy are examined as modifiable targets for change and existing preventive interventions employing these targets are described.

Description
The present study utilized longitudinal data from a high-risk community sample (n=254, 52.8% female, 47.2% children of alcoholics, 74% non-Hispanic Caucasian) to test questions concerning the effects of genetic risk, parental knowledge, and peer substance use on emerging adult substance use disorders (SUDs). Specifically, this study examined whether parental knowledge and peer substance use mediated the effects of parent alcohol use disorder (AUD) and genetic risk for behavioral undercontrol on SUD. The current study also examined whether genetic risk moderated effects of parental knowledge and peer substance use on risk for SUD. Finally, this study examined these questions over and above a genetic "control" which explained a large proportion of variance in the outcome, thereby providing a stricter test of environmental influences.
Analyses were performed in a path analysis framework. To test these research questions, the current study employed two polygenic risk scores. The first, a theory-based score, was formed using single-nucleotide polymorphisms (SNPs) from receptor systems implicated in the amplification of positive effects in the presence of new/exciting stimuli and/or pleasure derived from using substances. The second, an empirically-based score, was formed using a data-driven approach that explained a large amount of variance in SUDs. Together, these scores allowed the present study to test explanations for the relations among parent AUD, parental knowledge, peer substance use, and SUDs.
Results of the current study found that having parents with less knowledge or an AUD conferred greater risk for SUDs, but only for those at higher genetic risk for behavioral undercontrol. The current study replicated research findings suggesting that peer substance use mediated the effect of parental AUD on SUD. However, it adds to this literature by suggesting that some mechanism other than increased behavioral undercontrol explains relations among parental AUD, peer substance use, and emerging adult SUD. Taken together, these findings indicate that children of parents with AUDs comprise a particularly risky group, although likelihood of SUD within this group is not uniform. These findings also suggest that some of the most important environmental risk factors for SUDs exert effects that vary across level of genetic propensity.

Description
This study aims to examine how crossover relations from one parent relate to the other parent's view of familial relationships. The study examines mood state and psychological distress as variables that relate to each other and familial relationships. Home visits were scheduled with families of normally developing three-year olds. During these home visits, naturalistic observation and surveys were done. Researchers then conducted regression analyses to examine the relation between mood state, psychological distress, and familial relationships. The data showed that there were significant relations between one parents' psychological distress and how the other parent viewed the marital relationship, indicating a crossover relation between those two variables.

Description
The theory of biological sensitivity to context (BSC; Boyce & Ellis, 2005) posits that specific biological characteristics, such as vagal tone, may confer risk for physical and mental health outcomes for some children but promote health for others. High levels of resting respiratory sinus arrhythmia (RSA), an index of vagal tone, may confer susceptibility to the effects of the caregiving environment on child development. Consistent with BSC, I expected that, relative to infants with lower RSA, infants with higher RSA would demonstrate fewer behavior problems if their mothers reported fewer postpartum depressive symptoms, but more behavior problems if their mothers reported more postpartum depressive symptoms. I also evaluated whether observed child social engagement with their mothers mediated children's biological sensitivity to the effects of postpartum depressive symptoms on behavior problems in early childhood. I evaluated a mediated moderation model among a sample of 322 low-income Mexican American mother-infant dyads. As expected, the RSA x maternal depressive symptoms interaction, controlling for covariates, was a significant predictor of internalizing, externalizing and total behavior problems, and high vagal tone conferred susceptibility for externalizing behavior problems. Contrary to my hypothesis, children with low RSA may be more susceptible to the effects of maternal postpartum depressive symptoms on children's internalizing and total behavior problems, and child social engagement did not account for these effects. Among infants in economically disadvantaged families, lower RSA and fewer maternal depressive symptoms may promote resilience, and more research is needed to understand behavioral mediators of biological sensitivity.

Description
The first half-year of infancy represents a salient time in which emotion expression assumes a more psychological character as opposed to a predominantly physiological one. Although previous research has demonstrated the relations between early parenting and later emotional competencies, there has been less of a focus on differentiating positive and negative emotion expression across the early infancy period. Thus, the current study investigates the growth of positive and negative emotion expression across early infancy in a low-income, Mexican-American sample, and examines the development of emotion expression as a function of early maternal emotion socialization and prenatal stress. Participants included 322 mothers and their infants. Data were collected in participants' homes prenatally and when the infants were 12-, 18-, and 24-weeks old. Mothers were asked to interact with their infants in a semi-structured teaching task, and video-taped interactions of mother and infant behaviors were then coded. Data for mothers was collected at the prenatal and 12-week visits and data for infants was collected at the 12-, 18-, and 24-week visits. Prenatal stress was measured via two questionnaires (Daily Hassles Questionnaire and Perceived Stress Scale). Maternal socialization at 12 weeks was represented as a composite of four observational codes from the Coding Interactive Behavior coding system. Infant emotion expression was also globally rated across the 5-minute teaching task. Findings suggest that the normative development of emotion expression across early infancy is complex. Positive emotion expression may increase across the early infancy period whereas negative emotion expression decreases. Further, at 12 weeks, greater maternal emotion socialization relates to more infant positivity and less negativity, in line with current conceptualization of parenting. However, across time, greater early socialization predicted decreased positivity and was unrelated to negative emotion expression. Findings also suggest that prenatal stress does not relate to socialization efforts or to infant emotion expression. A better understanding of the nuanced development of positive and negative emotion development as a function of early parenting may have implications for early intervention and prevention in this high-risk population.

Description
The construct of adult emotional intelligence has gained increasing attention over the last 15 years given its significant socioemotional implications for the ability to label, understand, and regulate emotions. There is a gap, however, in understanding how emotional intelligence develops in children. Parenting is one of the most salient predictors of children’s behavior and the current study investigated its prospective link to children’s emotional intelligence. More preceisely, this study took a differentiated approach to parenting by examining the distinct contributions of maternal sensitivity and emotion socialization to children’s emotional intelligence. In addition, executive function, considered a “conductor” of higher-order skills and a neurocognitive correlate of emotional intelligence, was examined as a possible mechanism by which parenting influences emotional intelligence. Data were collected from 269 Mexican-American mother-child dyads during 2-year (parenting), 4.5-year (executive function), and 6-year (emotional intelligence) laboratory visits. Both parenting variables were assessed by objective observer ratings. Exeutive function and emotional intelligence were examined as latent constructs comprised of relevant parent-reported and objective measures. Due to a lack of adequate fit, the emotional intelligence variable was separated into two distinct latent constructs, emotion knowledge/understanding and emotion dysregulation. Results indicated that neither dimension of parenting was predictive of dimensions of emotional intelligence. On the other hand, children’s executive function was positively related to emotion knowledge. Finally, executive function did not emerge as a mediator of the relation between parenting and dimensions of emotional intelligence. Taken together, these findings highlight the need for a nuanced developmental and bioecological framework in the study of childen’s executive function and emotional intelligence.

Description
Dual language use is thought to afford certain cognitive advantages to bilingual children and may function as an additional resource to help low-income Mexican-American children achieve academically. Emotion regulation and executive functioning (e.g., inhibition) have been found to be particularly important in studies investigating pathways to early academic achievement. Understanding how we can capitalize on children’s bilingual abilities to strengthen their executive functioning and emotion regulation, or to offset problems in these domains, may be important to promote better educational outcomes and inform policy. Thus, the current study investigated the relation between emerging bilingualism, inhibition, emotion regulation, and academic achievement across early childhood in sample of 322 low-income, Mexican-American children. Data were collected in a laboratory space at child ages 36-, 54-, and 72-months. Bilingualism was indexed as the interaction of Spanish and English vocabulary, and a mediated moderation model was examined. Results provided further evidence that inhibition positively predicts academic achievement during early childhood. Greater Spanish language vocabulary indirectly predicted academic achievement while controlling for English language vocabulary, suggesting that children from immigrant families may benefit from maintaining their Spanish language abilities as they begin to immerse themselves in an English-speaking classroom. Advancing our understanding of the development of self-regulatory abilities within bilingual, immigrant populations could have significant implications for educational policy.
