Maternal major depression during early pregnancy is associated with impaired child executive functioning at 4.5 years of age.

BACKGROUND: Maternal depression is a serious condition that affects up to 1 in 7 pregnancies. Despite evidence linking maternal depression to pregnancy complications and adverse fetal outcomes, there remain large gaps in its identification and treatment. More work is needed to define the specific timing and severity of depression that most urgently requires intervention, where feasible, to protect maternal health and the developing fetus. OBJECTIVE: This study aimed to examine whether the timing and severity of maternal depression and/or anxiety during pregnancy affect child executive functioning at age 4.5 years. Executive functioning in the preschool years is a strong predictor of both school readiness and long-term quality of life. STUDY DESIGN: This longitudinal observational pregnancy cohort study included a sample of 323 mother-child dyads taking part in the Ontario Birth Study, an open pregnancy cohort in Toronto, Ontario, Canada. Maternal symptoms of depression and anxiety were assessed at 12 to 16 and 28 to 32 weeks of gestation and at the time of child testing at age 4.5 years using the 4-item Patient Health Questionnaire. Child executive functioning was measured during a home visit using standardized computerized administration of the Flanker test (a measure of attention) and the Dimensional Change Card Sort (a measure of cognitive flexibility). Stepwise linear regressions, controlling for possible confounding variables, were used to assess the predictive value of continuous measures of maternal depression and/or anxiety symptoms at each assessment time on the Flanker test and Dimensional Change Card Sort. Posthoc general linear models were used to assess whether maternal depression severity categories (no symptom, mild symptoms, or probable major depressive disorder) were helpful in identifying children at risk. RESULTS: Across all children, after controlling for potential confounds, greater maternal depressive symptoms at weeks 12 to 16 weeks of gestation predicted worse performance on both the Flanker test (ΔR2=0.058; P<.001) and the Dimensional Change Card Sort (ΔR2=0.017; P=.018). Posthoc general linear modeling further demonstrated that the children of mothers meeting the screening criteria for major depression in early pregnancy scored 11.3% lower on the Flanker test and 9.8% lower on the Dimensional Change Card Sort than the children of mothers without maternal depressive symptoms in early pregnancy. Mild depressive symptoms had no significant effect on executive function scores. There was no significant effect of anxiety symptoms or maternal antidepressant use in early pregnancy or pandemic conditions or maternal symptoms in later pregnancy or at the time of child testing on either the Flanker or Dimensional Change Card Sort results. CONCLUSION: This study demonstrated that fetal exposure to maternal major depression, but not milder forms of depression, at 12 to 16 weeks of gestation is associated with impaired executive functioning in the preschool years. Child executive functioning is crucial for school readiness and predicts long-term quality of life. This emphasizes an urgent need to improve the recognition and treatment of maternal major depression, particularly in early pregnancy, to limit its negative effects on the patient and on child cognitive development.

Cognitive and Emotional Well-Being of Preschool Children Before and During the COVID-19 Pandemic.

Importance: The association between COVID-19 social disruption and young children's development is largely unknown. Objective: To examine associations of pandemic exposure with neurocognitive and socioemotional development at 24 and 54 months of age. Design, Setting, and Participants: This cross-sectional study evaluated associations between pandemic exposure vs nonexposure and developmental outcomes with covariate adjustment using data from the Ontario Birth Study collected between February 2018 and June 2022. Eligible participants were children aged 24 and 54 months. Data were analyzed from June to November 2022. Exposure: COVID-19 pandemic exposure defined as assessment after March 11, 2020. Main Outcome and Measures: Neurodevelopmental assessment using the ASQ-3 (Ages and Stages Questionnaire, Third Edition) and MCHAT-R (Modified Checklist for Autism in Toddlers, Revised) at 24 months of age, and neurocognitive and socioemotional assessment using the National Institutes of Health Toolbox at 54 months of age. Results: A total of 718 children at age 24 months (mean [SD] age, 25.6 [1.7] months; 342 female [47.6%]; 461 White [64.2%]) and 703 at age 54 months (mean [SD] age, 55.4 [2.6] months; 331 female [47.1%]; 487 White [69.3%]) were included. At 24 months of age, 460 participants (232 female [50.4%]) were assessed during the pandemic (March 17, 2020, to May 17, 2022) and 258 (110 female [42.6%]) were assessed prepandemic (April 17, 2018, to March 10, 2020). At 54 months of age, 286 participants (129 female [45.1%]) were assessed from March 14, 2020, to June 6, 2022, and 417 (202 female [48.4%]) were assessed from February 8, 2018, to March 10, 2020. At 24 months of age, pandemic-exposed children had reduced risk of problem-solving difficulties using cutoff scores (odds ratio [OR], 0.33; 95% CI, 0.18-0.62; P = .005) and higher problem-solving (B, 3.93; 95% CI, 2.48 to 5.38; P < .001) compared with nonexposed children. In contrast, pandemic-exposed children had greater risk for personal-social difficulties using cutoff scores (OR, 1.67; 95% CI, 1.09-2.56; P = .02) and continuous scores (B, -1.70; 95% CI, -3.21 to -0.20; P = .02) compared with nonexposed children. At 54 months of age, pandemic-exposed children had higher receptive vocabulary (B, 3.16; 95% CI, 0.13 to 6.19; P = .04), visual memory (B, 5.95; 95% CI, 1.11 to 10.79; P = .02), and overall cognitive performance (B, 3.89; 95% CI, 0.73 to 7.04; P = .02) compared with nonexposed children, with no differences in socioemotional development. Conclusions and Relevance: This cross-sectional study found both positive and negative associations between pandemic exposure and preschool children's cognitive and emotional well-being within a relatively socioeconomically advantaged sample.

Association between maternal sensitivity and child receptive language development: Quasi-causal evidence using a sibling comparison design.

Observational studies have shown that caregiver sensitivity predicts child language skills. These studies, however, have entirely relied on between-family designs (single parent-child dyad per family), which cannot rule out the contribution of shared family confounds (e.g., genetics, books in home). The current study investigates whether observed caregiver sensitivity predicts changes in child receptive language using a sibling comparison design. Participants were 890 Canadian children (51.7% male; 52.4% White) nested within 447 families from diverse socioeconomic backgrounds with children between the ages of 2 and 3.5 years (Wave 1) and 3.5 and 5 years (Wave 2). Independent observers provided ratings of maternal sensitivity with each sibling using several coding protocols (i.e., Coding of Attachment-Related Parenting and the Parent-Child Interaction System). Child receptive language was assessed using the Peabody Picture Vocabulary Test. Maternal sensitivity predicted within-person change in receptive language. That is, the sibling that receives comparatively more sensitivity from the caregiver showed more development in language over time when compared to their sibling. The obverse association, child language to later maternal sensitivity, was not observed, pointing to a unidirectional association of maternal sensitivity on child receptive language. Our sibling comparison design rules out the role of shared family confounders, which provides a strong test of causal processes within an observational design.

Teaching empathy to mental health practitioners and trainees: Pairwise and network meta-analyses.

OBJECTIVE: Empathy is a foundational therapeutic skill and a key contributor to client outcome, yet the best combination of instructional components for its training is unclear. We sought to address this by investigating the most effective instructional components (didactic, rehearsal, reflection, observation, feedback, mindfulness) and their combinations for teaching empathy to practitioners. METHOD: Studies included were randomized controlled trials targeted to mental health practitioners and trainees, included a quantitative measure of empathic skill, and were available in English. A total of 36 studies (37 samples) were included (N = 1,616). Two reviewers independently extracted data. Data were pooled by using random-effects pairwise meta-analysis and network meta-analysis (NMA). RESULTS: Overall, empathy interventions demonstrated a medium-to-large effect (d = .78, 95% CI [.58, .99]). Pairwise meta-analysis showed that one of the six instructional components was effective: didactic (d = .91 vs. d = .39, p = .02). None of the program characteristics significantly impacted intervention effectiveness (group vs. individual format, facilitator type, number of sessions). No publication bias, risk of bias, or outliers were detected. NMA, which allows for an examination of instructional component combinations, revealed didactic, observation, and rehearsal were included among the most effective components to operate in combination. CONCLUSIONS: We have identified instructional component, singly (didactic) and in combination (didactic, rehearsal, observation), that provides an efficient way to train empathy in mental health practitioners.

Linking early maternal input during shared reading to later theory of mind through receptive language and executive function: A within- and between-family design.

This study explored whether early maternal input during shared reading predicted later theory of mind (ToM) understanding through children's receptive language and executive function (EF). Maternal input plays a prominent role in the development of children's language skills, which are crucial for both EF and ToM development. There is also an abundance of behavioral evidence suggesting a directional link from EF to ToM. This relation raises the possibility of a cognitive cascade in which maternal input during shared reading promotes ToM development sequentially through receptive language and EF. The sample included 656 children clustered within 328 ethnically and sociodemographically diverse families. The shared reading sessions occurred when the younger and older siblings were 1.5 and 4 years old, respectively. Receptive language, EF, and ToM were measured when the siblings were approximately 5 years old to account for age differences. Multilevel modeling using Bayesian estimation was used to account for the effect of family-wide confounds (i.e., shared between the siblings in the family) while isolating child-specific processes (i.e., unique to each child within the family). The results supported two indirect paths from shared reading to children's ToM: one through receptive language alone and another that operated sequentially through receptive language and EF. These paths were observed only at the family level. These findings emphasize the importance of maternal input during early shared reading for cognitive development and suggest a cascade from maternal input to ToM via language and EF during the preschool period.

Teaching home-visitors to support responsive caregiving: A cluster randomized controlled trial of an online professional development program in Brazil.

BACKGROUND: Home-visiting programs are a common and effective public health approach to promoting parent and child well-being, including in low- and middle-income countries. The World Health Organization and UNICEF have identified responsive caregiving as one key component of the nurturing care children need to survive and thrive. Nonetheless, the importance of responsive caregiving and how to coach it is often overlooked in trainings for staff in home-visiting programs. METHODS: To determine whether it is possible to enhance home-visitors' understanding of responsive caregiving and how to coach it, we conducted a cluster randomized controlled trial with 181 staff working in Brazil's national home-visiting program. We used a computerized random number generator to randomly assign half of participants to take an online professional development course about responsive caregiving immediately and the other half to a waitlist. Individuals assessing outcome data were blind to group assignment. RESULTS: Compared to those in the control group (N = 90, both randomized and analyzed), participants assigned to take the course (N = 91, both randomized and analyzed) were more knowledgeable about responsivity (Cohen's d = 0.64, 95% Confidence Interval (CI) = 0.34, 0.94) and its importance for children's socioemotional (odds ratio (OR) = 1.88, 95% CI = 1.00, 3.50) and cognitive (OR = 2.57, 95% CI = 1.15, 5.71) development, better able to identify responsive parental behaviors in videotaped interactions (d = 1.86, 95% CI = 1.51, 2.21), and suggested more effective strategies for coaching parents on responsivity (d = 0.51, 95% CI = 0.21, 0.80) and tracking goal implementation (OR = 3.20, 95% CI = 1.28, 7.99). There were no significant changes in participants' tendency to encourage goal setting and reflection, or their perspective-taking skills. Participants were very satisfied with the course content and mode of delivery and there was no drop-out from the program. CONCLUSIONS: A short, online professional development program created moderate to large improvements in home-visitors' knowledge and intended coaching practices. This suggests that such programs are feasible, even in low-income and rural areas, and provide a low-cost, scalable option for possibly maximizing the impact of home-visiting programs - particularly with regard to parental responsivity, and in turn, child outcomes.

COVID-19 disruption gets inside the family: A two-month multilevel study of family stress during the pandemic.

Developmental research during COVID-19 suggests that pandemic-related disruptions in family relationships are associated with children's mental health. Most of this research has focused on 1 child per family, thereby obfuscating patterns that are differentially operative at the family-wide (i.e., between-family) versus child-specific (i.e., within-family) levels of analysis. Thus, the current study evaluates multilevel, longitudinal associations between COVID-19 disruption, family relationships, and caregiver/child mental health using a sibling comparison methodology. Caregivers (N = 549 families with 1098 children between 5 and 18 years old) were recruited from the Prolific research panel (73% White-European; 68% female; 76% United Kingdom, 19% U.S.A.; median 2019 income $50,000-$74,999). Caregiver reports of COVID-19 disruption, psychological distress, family functioning, parenting, and child mental health (for 2 children per family) were provided during May (time 1) and July (time 2) 2020. A Bayesian multilevel path analysis with random effects revealed: (a) families were experiencing difficulties across domains when COVID-19 disruption was high; (b) COVID-19 disruption corresponded to greater sibling differences in mental health; and (c) the sibling with poorer mental health received lower quality parenting over time, especially in families who reported higher levels of differential parenting. Findings suggest that understanding children's mental health difficulties during COVID-19 requires a family system lens due to the multiple ways these consequences permeate across the family unit. Comprehensive interventions for children's mental health during this time will likely require an examination of caregiver, sibling, and whole-family dynamics in the context of evidence-based telehealth practice.

Teaching Parents to Be Responsive: A Network Meta-analysis.

CONTEXT: Children who receive more responsive care during their early childhood tend to exhibit stronger cognitive development, mental well-being, and physical health across their life course. OBJECTIVE: Determine how to design effective responsivity training programs for caregivers. DATA SOURCES: We searched seven electronic databases through October 2020. STUDY SELECTION: Randomized trials (k = 120) of programs training parents of children ages 0 to 6 to be more responsive. DATA EXTRACTION: Two reviewers independently extracted data. Data were pooled by using random-effects pairwise and network meta-analyses. RESULTS: Programs had, on average, a medium effect (d = 0.56; 95% confidence interval [CI]: 0.47 to 0.65). The most effective programs included didactic teaching and opportunities for parents to observe models, practice skills, and receive feedback (d = 1.07; 95% CI: 0.37 to 1.77), or all these instructional methods in addition to reflection (d = 0.86; 95% CI: 0.64 to 1.09). Programs that had participants observe examples of responsivity (d = 0.70; 95% CI: 0.57 to 0.83), used researchers as facilitators (d = 0.89; 95% CI: 0.66 to 1.12), assigned homework (d = 0.85; 95% CI: 0.66 to 1.02), and had a narrow scope (d = 0.72; 95% CI: 0.57 to 0.87) were more effective than those that did not. LIMITATIONS: Most samples included only mothers from Western countries and lacked follow-up data. CONCLUSIONS: Having parents observe examples of responsive caregiving and complete home-practice in short, focused programs may be an effective, scalable approach to enhancing responsivity in the general population and reducing inequalities in child development.

The COVID-19 Family Stressor Scale: Validation and Measurement Invariance in Female and Male Caregivers.

The COVID-19 pandemic has raised significant concerns regarding the effect of social disruptions on parental mental health, family well-being, and children's adjustment. Due to the pace of the pandemic, measures of pandemic-related disruption have not been subject to rigorous empirical validation. To address this gap, a multi-national sample (United Kingdom, 76%; United States, 19%; Canada, 4%, and Australia, 1%) of 372 female caregivers and 158 male caregivers of 5-18-year-old children was recruited online. Participants completed a survey including a 25-item scale indexing disruption in finances, basic needs, personal and family welfare, career/education, household responsibilities, and family relationships related to the pandemic. An exploratory factor analysis yielded an optimal three-factor solution: factors included Income Stress (five items related to income, debt, and job loss; loadings ranged from 0.57 to 0.91), Family Stress (seven items related to family altercations and child management; loadings from 0.57 to 0.87), and Chaos Stress (four items related to access to supplies, crowded shopping areas, news coverage; loadings from 0.53 to 0.70). Multiple-group confirmatory factor analysis demonstrated measurement invariance of each factor across female and male caregivers, indicating that factor structure, loadings, and thresholds were equivalent across groups. Composites reflective of each factor were computed, and Mann-Whitney U tests indicated that female caregivers consistently scored higher than male caregivers on COVID-19 stressors related to income, family, and chaos. Finally, concurrent validity was demonstrated by significant bivariate correlations between each scale and caregiver, family, and child outcomes, respectively. This demonstrates the validity of the COVID-19 Family Stressor Scale for use with female and male caregivers in family-based research. The current sample was predominantly White-European, married/common-law, and had at least some post-secondary education. Additional sampling and validation efforts are required across diverse ethnic/racial and socioeconomic groups.

A Family Socialization Model of Transdiagnostic Risk for Psychopathology in Preschool Children.

This longitudinal study examined the presence of general (P) and specific internalizing (INT) and externalizing (EXT) psychopathology factors in a community sample of preschool children. We assessed child and contextual correlates of P, INT, and EXT, and tested a model connecting socioeconomic risk to these factors through family socialization processes and child cognitive abilities. Participants were 501 children recruited at birth and followed up at 18 months and 3 years. Child and family functioning were measured using parental reports, observation, and standardized assessments. Both mothers and their partners reported on children's mental health, permitting the estimation of a trifactor model of psychopathology that captured caregivers' shared and unique perspectives with respect to P, INT, and EXT. Results revealed several transdiagnostic correlates of the common-perspective P factor, including family income, maternal education, maternal depression, and maternal responsiveness, as well as marginal associations with sibling negativity and children's language and theory of mind abilities. Several shared and unique correlates of INT and EXT were also observed. Structural equation modelling revealed that the effects of family income and maternal education on P operated indirectly through maternal responsiveness, while the effects of maternal education on INT and EXT operated through maternal reflective capacity, albeit in opposite directions. Together, these results suggest that the effects of socioeconomic disadvantage on general psychopathology are organized in a temporal cascade from distal to proximal risk.

The disparate impact of COVID-19 on the mental health of female and male caregivers.

Caregiver mental health is crucial to the wellbeing of children. This is most apparent when caregivers face high levels of stress or life adversity. To study this phenomenon in the current global context, this study examined the relation between stress/disruption from the COVID-19 pandemic and the mental health of female and male caregivers. Pre-pandemic childhood adversity was considered as a moderator of this association. A multi-national sample (United Kingdom, 76%; United States, 19%; Canada, 4%, and Australia, 1%) was recruited in May 2020, of whom 348 female and 143 male caregivers of 5-18 year-old children provided data on the constructs of interest. At this time, caregivers reported on their history of adverse childhood experiences (ACEs) and COVID stress/disruption. About two months later (July 2020) caregiver mental health was evaluated. We examined differences between female and male caregivers on ACEs, COVID stress/disruption, and mental health (distress, anxiety, substance use, and posttraumatic stress). Main and interactive effects of ACEs and COVID stress/disruption on each mental health outcome were examined. Female caregivers reported higher COVID stress/disruption, more ACEs, and greater distress, anxiety, and posttraumatic stress symptoms compared to male caregivers. Among female caregivers, higher COVID stress/disruption and more adverse childhood experiences (ACEs) independently predicted all mental health outcomes, consistent with a stress accumulation model. Among male caregivers, a pattern of interactions between COVID stress/disruption and ACEs suggested that the effects of COVID stress/disruption on mental health was stronger for those with higher ACEs, especially for substance use, consistent with a stress sensitization model. Higher levels of stress and mental health difficulties among female caregivers suggests a disproportionate burden due to pandemic-related disruption compared to male caregivers. Findings speak to the disparate effects of COVID-19 on the mental health of female compared to male caregivers, and the role of pre-existing vulnerabilities in shaping current adaptation.

What makes for responsive family interactions? Disentangling individual, family-level, and socioeconomic contributions.

Families function best, and children benefit the most, when familial interactions are characterized by responsivity-an understanding and consideration of other people's thoughts and feelings. How responsive people are during interactions with others is a product of individual propensities, observed family norms, and unique relationship patterns, though these influences are often hard to disentangle. In the current study, we used a Social Relations Model (SRM) to parse out the extent to which being responsive during family interactions is attributable to individual traits or familial tendencies. Mothers, fathers, and two children each interacted with every other person in the family (N = 198 families) and each person's behavior was coded for the level of responsivity they displayed toward their interactional partner. Data were modeled using a multilevel formulation of the SRM. Between 15% and 30% of the variance in individual's responsivity was attributable to stable traits, with parents tending to be more consistent across all interactional partners than their children. On average, 14% of the variance in responsivity was shared across all members of a given family. Income explained 28% of family-level variance, while other family characteristics, including parent education, parent mental health, interparental conflict, and household chaos, explained little to no variance. Furthermore, it was found that parents contributed more to the family tone of responsivity than did their children. These results provide new insights into what makes family members responsive toward one other and suggest there are likely benefits of providing supports across individual-, family-, and financial-levels to enhance family responsivity.

Linking Quality and Quantity of Parental Linguistic Input to Child Language Skills: A Meta-Analysis.

This meta-analysis examined associations between the quantity and quality of parental linguistic input and children's language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of linguistic input. For quality and quantity of parental linguistic input, effect sizes were stronger when input was observed in naturalistic contexts compared to free play tasks. For quality of parental linguistic input, effect sizes also increased as child age and observation length increased. Effect sizes were not moderated by socioeconomic status or child gender. Findings highlight parental linguistic input as a key environmental factor in children's language skills.

Cross-Cultural Adaptation and Validation of the Brazilian Portuguese Version of an Observational Measure for Parent-Child Responsive Caregiving.

Responsive caregiving is the dimension of parenting most consistently related to later child functioning in both developing and developed countries. There is a growing need for efficient, psychometrically sound and culturally appropriate measurement of this construct. This study describes the cross-cultural validation in Brazil of the Responsive Interactions for Learning (RIFL-P) measure, requiring only eight minutes for assessment and coding. The cross-cultural adaptation used a recognized seven-step procedure. The adapted version was applied to a stratified sample of 153 Brazilian mother-child (18 months) dyads. Videos of mother-child interaction were coded using the RIFL-P and a longer gold standard parenting assessment. Mothers completed a survey on child stimulation (18 months) and child outcomes were measured at 24 months. Internal consistency (α = 0.94), inter-rater reliability (r = 0.83), and intra-rater reliability (r = 0.94) were all satisfactory to high. RIFL-P scores were significantly correlated with another measurement of parenting (r's ranged from 0.32 to 0.47, p < 0.001), stimulation markers (r = 0.34, p < 0.01), and children's cognition (r = 0.29, p < 0.001), language (r = 0.28, p < 0.001), and positive behavior (r = 0.17, p < 0.05). The Brazilian Portuguese version is a valid and reliable instrument for a brief assessment of responsive caregiving.

Do Mothers or Children Lead the Dance? Disentangling Individual and Influence Effects During Conflict.

Are mother-child conflict discussions shaped by time-varying, reciprocal influences, even after accounting for stable contributions from each individual? Mothers were filmed discussing a conflict for 5 min, separately with their younger (ages 5-9, N = 217) and older (ages 7-13, N = 220) children. Each person's conflict constructiveness was coded in 20-s intervals and data were analyzed using dynamic structural equation modeling, which separates individual and influence effects. Children influenced their mothers' behavior under certain conditions, with evidence for developmental differences in the magnitude and direction of influence, whereas mothers did not influence their children under any circumstance. Results are discussed in the context of child effects on parent behavior and changes in parenting across middle childhood.

Parenting Behavior and Child Language: A Meta-analysis.

CONTEXT: Early language development supports cognitive, academic, and behavioral success. Identifying modifiable predictors of child language may inform policies and practices aiming to promote language development. OBJECTIVE: To synthesize results of observational studies examining parenting behavior and early childhood language in typically developing samples. DATA SOURCES: Searches were conducted in Medline, Embase, PsycINFO, Web of Science, and Dissertation Abstracts (1967 to 2017). STUDY SELECTION: Studies had 1 of 2 observational measures of parenting behavior (i.e., sensitive responsiveness or warmth) and a measure of child language. DATA EXTRACTION: Data from 37 studies were extracted by independent coders. Estimates were examined by using random-effects meta-analysis. RESULTS: Two meta-analyses were conducted, which examined (1) the association between sensitive-responsive parenting and child language (k = 36; r = 0.27; 95% confidence interval: 0.21 to 0.33); and (2) the association between parental warmth and child language (k = 13; r = 0.16; 95% confidence interval: 0.09 to 21). The pooled effect size for the association between sensitive responsiveness and child language was statistically higher than that of warmth and child language. The association between sensitive responsiveness and child language was moderated by family socioeconomic status (SES): effect sizes were stronger in low and diverse SES groups compared with middle to upper SES groups. Effect sizes were also stronger in longitudinal versus cross-sectional studies. LIMITATIONS: Results are limited to typically developing samples and mother-child dyads. Findings cannot speak to causal processes. CONCLUSIONS: Findings support theories describing how sensitive parenting may facilitate language and learning.

Cognitive sensitivity and child receptive vocabulary: A between- and within-family study of mothers and sibling pairs.

This study examined the association between observed cognitive sensitivity (CS) during family interactions and children's receptive vocabulary for older and younger siblings. Maternal and sibling CS was considered and associations were explored at the family-wide (between-family) and child-specific (within-family) levels of analysis. The interactions of mothers and 2 children per family were observed when younger siblings were 3.15 years (SD = 0.27) and older siblings were 5.57 years (SD = 0.77). Each dyad (mother-older sibling, mother younger-sibling, and sibling dyad, N = 385) completed a Lego building task, and there were two directional CS scores per interaction (e.g., mother toward older sibling, and older sibling toward mother). Results from multilevel models indicated that younger siblings' vocabulary was associated with the average level of CS for mothers and older siblings, independently. Conversely, older siblings' vocabulary was associated with the average level of maternal CS and child-specific maternal CS. Findings suggest that the relationship between CS and vocabulary operates across the family system and differs for older and younger siblings.

The development of internalizing problems in early childhood: The importance of sibling clustering.

Within family sibling clustering of internalizing problems is examined during the early childhood period. Sibling clustering, the ongoing sibling similarity in internalizing problems, may be a result of heritability of internalizing problems, as well as shared environmental effects. Clustering may also result from the time-varying influence of sibling socialization, where 1 sibling is teaching or modeling internalizing problems to the other sibling. We compared a traditional cross-lagged panel model with a recently developed multilevel statistical model that differentiates the 2 mechanisms. Sibling clustering was operationalized as the family level, time-invariant variance in internalizing problems, and differentiated from sibling socialization, the cross-lagged (time-varying) association between earlier child behavior and later sibling behavior. A 3-wave longitudinal study tracked 916 children (age M = 3.46, SD = 2.23) in 397 families using a 2-parent composite score of internalizing problems. Results suggest the importance of accounting for sibling clustering in the context of a panel study, as its inclusion in the model eliminated the identified time-varying, sibling socialization effects.

The Development of Empathic Concern in Siblings: A Reciprocal Influence Model.

This study utilized actor-partner interdependence modeling to examine the bidirectional effects of younger (Mage  = 18 months) and older siblings (Mage  = 48 months) on later empathy development in a large (n = 452 families), diverse (42% immigrant) Canadian sample. Controlling for parenting, demographic characteristics, sibling relationship quality, and within-child stability in empathic concern, both younger and older siblings' observed empathic concern uniquely predicted relative increases in the other's empathy over a period of 18 months. The strength of the partner effects did not differ by birth order. Sex composition moderated the younger sibling partner effect, whereas age gap moderated the older sibling partner effect. This study highlights the important role that siblings play in enhancing the development of care and concern for others.
