A longitudinal study examining the associations between prenatal and postnatal maternal distress and toddler socioemotional developmental during the COVID-19 pandemic.

Elevated psychological distress, experienced by pregnant women and parents, has been well-documented during the COVID-19 pandemic. Most research focuses on the first 6-months postpartum, with single or limited repeated measures of perinatal distress. The present longitudinal study examined how perinatal distress, experienced over nearly 2 years of the COVID-19 pandemic, impacted toddler socioemotional development. A sample of 304 participants participated during pregnancy, 6-weeks, 6-months, and 15-months postpartum. Mothers reported their depressive, anxiety, and stress symptoms, at each timepoint. Mother-reported toddler socioemotional functioning (using the Brief Infant-Toddler Social and Emotional Assessment) was measured at 15-months. Results of structural equation mediation models indicated that (1) higher prenatal distress was associated with elevated postpartum distress, from 6-weeks to 15-months postpartum; (2) associations between prenatal distress and toddler socioemotional problems became nonsignificant after accounting for postpartum distress; and (3) higher prenatal distress was indirectly associated with greater socioemotional problems, and specifically elevated externalizing problems, through higher maternal distress at 6 weeks and 15 months postpartum. Findings suggest that the continued experience of distress during the postpartum period plays an important role in child socioemotional development during the COVID-19 pandemic.

Social support buffers the impact of pregnancy stress on perceptions of parent-infant closeness during the COVID-19 pandemic.

Pregnant individuals and parents have experienced elevated mental health problems and stress during COVID-19. Stress during pregnancy can be harmful to the fetus and detrimental to the parent-child relationship. However, social support is known to act as a protective factor, buffering against the adverse effects of stress. The present study examined whether (1) prenatal stress during COVID-19 was associated with parent-infant closeness at 6 months postpartum, and (2) social support moderated the effect of prenatal stress on the parent-infant relationship. In total, 181 participants completed questionnaires during pregnancy and at 6 months postpartum. A hierarchical linear regression analysis was conducted to assess whether social support moderated the effect of stress during pregnancy on parent-infant closeness at 6 months postpartum. Results indicated a significant interaction between prenatal stress and social support on parents' perceptions of closeness with their infants at 6 months postpartum (ß = .805, p = .029); parents who experienced high prenatal stress with high social support reported greater parent-infant closeness, compared to those who reported high levels of stress and low social support. Findings underscore the importance of social support in protecting the parent-infant relationship, particularly in times of high stress, such as during the COVID-19 pandemic.

Individuos y progenitores en estado de embarazo experimentan elevados problemas de salud mental y estrés durante el COVID­19. El estrés durante el embarazo puede ser dañino para el feto y perjudicial para la relación progenitor­niño. Sin embargo, es sabido que el apoyo social actúa como un factor de protección, sirviendo como agente amortiguador contra los adversos efectos del estrés. El presente estudio longitudinal examinó si 1) el estrés prenatal durante el COVID­19 se asociaba con la cercanía madre­infante a los seis meses después del parto, y 2) el apoyo social moderaba el efecto del estrés prenatal en la relación madre­infante. Un total de 181 participantes completaron cuestionarios durante el embarazo y a los seis meses después del parto. Un análisis de regresión lineal jerárquico se llevó a cabo para evaluar si el apoyo social moderaba el efecto del estrés durante el embarazo en cuanto a la cercanía progenitor­infante a los seis meses después del parto. Los resultados indicaron una interacción significativa entre el estrés prenatal y el apoyo social sobre las percepciones que los progenitores tenían de la cercanía con sus infantes a los seis meses después del parto (ß = .805, p = .029); los progenitores que experimentaron un alto estrés prenatal con un alto apoyo social reportaron una mayor cercanía progenitor­infante, comparados con aquellos que reportaron altos niveles de estrés y bajo apoyo social. Los resultados subrayan la importancia del apoyo social para proteger la relación progenitor­infante, particularmente en épocas de alto estés, tal como durante la pandemia del COVID­19.

Les personnes enceintes et les parents font l'expérience de plus grands problèmes de santé mentale et de plus de stress durant la crise du COVID­19. Le stress durant la grossesse peut être néfaste pour le foetus et vient au détriment de la relation parent­enfant. Cependant l'on sait que le soutien social est un facteur de protection, faisant tampon face aux effets adverses du stress. Cette étude longitudinale a examiné si 1) le stress prénatal durant le COVID­19 était lié à la proximité mère­nourrisson à six mois postpartum, et 2) le soutien social a modéré l'effet du stress prénatale sur la relation mère­nourrisson. En tout 181 participants ont rempli des questionnaires durant la grossesse et à sic mois postpartum. Une analyse de régression linéaire hiérarchique a été faite pour évaluer si le soutien social a modéré l'effet du stress durant la grossesse sur la proximité parent­nourrisson à six mois postpartum. Les résultats ont indiqué une interaction importante entre le stress prénatal et le soutien social sur les perceptions des parents de la proximité avec leurs nourrissons à six mois postpartum (ß = ,805, p = ,029); les parents qui ont fait l'expérience d'un stress prénatal élevé avec un soutien social élevé ont signalé une plus grande proximité parent­nourrisson, comparé à ceux ayant signalé des niveaux de stress élevés et un faible soutien social. Les résultats soulignent l'importance du soutien social dans la protection de la relation parent­nourrisson, particulièrement en temps de stress élevé, comme durant la pandémie de COVID­19.

Attachment expectations moderate links between social support and maternal adjustment from 6 to 18 months postpartum.

Significant links exist between one's perception of available social support and mental health outcomes, including during the transition to motherhood. Yet, attachment theory posits that individuals do not benefit equally from social support. As such, we examined the influence of attachment representations (i.e., secure base script knowledge) as they potentially moderate links between social support and psychological distress in a 1-year longitudinal study of an ethnically diverse (56% White) sample of infant-mother dyads. We hypothesized that higher social support would predict lower maternal psychological distress and this relation would be strongest in those with higher secure base script knowledge. Results indicated that maternal perceptions of social support were significantly negatively correlated with psychological distress. Analyses revealed that secure base script scores significantly moderated these associations. Interestingly, for those high in script knowledge, low social support predicted greater psychological distress. For those low in script knowledge, social support was unrelated to psychological distress. This pattern suggested that those who expect care (i.e., high secure base script knowledge) but receive minimal support (i.e., low perceived social support) find motherhood uniquely dysregulating. Practitioners may do well to examine individuals' attachment expectations in relation to their current social support.

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.

Depression, parenting and the COVID-19 pandemic in Canada: results from three nationally representative cross-sectional surveys.

OBJECTIVES: Depression is associated with problems in functioning in many aspects of life, including parenting. COVID-19 has increased risk factors for depression. We investigated the prevalence of depression among parents during the pandemic and the association with dysfunctional parenting. DESIGN: Canadian nationwide cross-sectional study. SETTING AND PARTICIPANTS: The 2020 and 2021 Surveys on COVID-19 and Mental Health (SCMH) and the Canadian Community Health Survey (CCHS) (2015‒2019). Responding sample sizes for parents were 3121 for the 2020-SCMH; 1574 for the 2021-SCMH and 6076 for the CCHS. PRIMARY OUTCOME MEASURES: All three surveys collected information on symptoms of major depressive disorder (MDD). The SCMH measured harsh parenting. RESULTS: Based on data from the 2021-SCMH collected during wave 3 of COVID-19, 14.4% of fathers and 21.2% of mothers screened positive for MDD. These prevalence estimates were similar to those from the 2020-SCMH during wave 2, but at least two times higher than pre-COVID-19 estimates from the CCHS. Multivariate analyses revealed a linear association between MDD and harsh parenting. COVID-19-related stressors were associated with harsh parenting. Among mothers, feeling lonely or isolated because of COVID-19 was a risk factor for harsh parenting; among fathers, being a front-line worker was a risk factor. Meditation was a protective factor for mothers. CONCLUSIONS: After years of stability, the prevalence of MDD increased substantially among Canadian parents during the pandemic. Ongoing monitoring is vital to determine if elevated levels of depression persist because chronic depression increases the likelihood of negative child outcomes. Programmes aimed at addressing depression and bolstering parenting skills are needed as families continue to face stressors associated with COVID-19.

Protocol for the COVID-19 Wellbeing and Stress Study: a longitudinal study of parent distress, biological stress and child biopsychosocial development during the pandemic and beyond.

INTRODUCTION: The COVID-19 pandemic has had a unique impact on the mental health and well-being of pregnant individuals and parents of young children. However, the impact of COVID-19-related stress during pregnancy on early child biopsychosocial development, remains unclear. The COVID-19 Wellbeing and Stress Study will: (1) investigate the impact of different forms of prenatal stress experienced during the pandemic (including objective hardship, perceived psychological distress and biological stress) on child stress biology, (2) examine the association between child stress biology and child developmental outcomes, (3) determine whether child stress biology acts as a mechanism linking prenatal stress to adverse child developmental outcomes and (4) assess whether gestational age at the onset of the COVID-19 pandemic or child sex, moderate these associations. METHODS AND ANALYSES: The COVID-19 Wellbeing and Stress Study is a prospective longitudinal study, consisting of six time points, spanning from pregnancy to 3 years postpartum. The study began in June 2020, consisting of 304 pregnant people from Ontario, Canada. This multimethod study is composed of questionnaires, biological samples, behavioural observations and developmental assessments ETHICS AND DISSEMINATION: This study was approved by the Hamilton Integrated Research Ethics Board (#11034) and the Mount Saint Vincent University Research Ethics Board (#2020-187, #2021-075, #2022-008). Findings will be disseminated through peer-reviewed presentations and publications, community presentations, and electronic forums (social media, newsletters and website postings).

Predictors of harsh parenting practices and inter-partner conflict during the COVID-19 pandemic in Ontario, Canada: a cross-sectional analysis from the Ontario Parent Survey.

OBJECTIVES: Guided by the bioecological model, the purpose of this study was to examine the associations of (1) individual level factors (sociodemographic, health behaviour and mental health), (2) family (micro) level COVID-19 experiences (difficulty with household management, managing child mood and behaviour, and pandemic-related positive experiences) and (3) community (macro) level factors (residential instability, ethnic concentration, material deprivation and dependency, an indicator of age and labour force) with harsh parenting practices and inter-partner conflict during the early lockdown of the COVID-19 pandemic in Ontario, Canada. DESIGN: A cross-sectional analysis of data from the Ontario Parent Survey. SETTING: A convenience sample of 7451 caregivers living in Ontario, Canada, at the time of baseline data collection (May-June 2020). PARTICIPANTS: Caregivers aged 18 years and older with children 17 years or younger. OUTCOME MEASURES: Parenting practices over the past 2 months was assessed using a published modification of the Parenting Scale. The frequency of inter-partner conflict over the past month was assessed using the Marital Conflict scale. RESULTS: Individual (sociodemographic factors, alcohol use, and higher depressive and anxiety symptoms) and family (difficulties with managing the household and child mood and behaviour) level factors were positively associated with inter-partner conflict and harsh parenting practices. Having fewer positive experiences (eg, performing activities with children), and economic adversity at the family level were positively associated with inter-partner conflict but inversely associated with harsh parenting. At the community level, residential instability was negatively associated with harsh parenting practices. CONCLUSIONS: Individual and family level factors were associated with harsh parenting and inter-partner conflict. The associations of fewer positive experiences and economic hardship with harsh parenting practices may be more complex than initially thought. Efforts that raise awareness and address caregiver mental health concerns are needed as part of the pandemic response to promote positive inter-partner and parent-child interactions.

Social engagement and allostatic load mediate between adverse childhood experiences and multimorbidity in mid to late adulthood: the Canadian Longitudinal Study on Aging.

BACKGROUND: Adverse childhood experiences (ACEs) are associated with multimorbidity in adulthood. This link may be mediated by psychosocial and biological factors, but evidence is lacking. The current study evaluates this mediation model. METHOD: We analyzed data from the Canadian Longitudinal Study of Aging (N = 27 170 community participants). Participants were 45-85 years at recruitment, when allostatic load and social engagement data were collected, and 3 years older at follow-up, when ACEs and multimorbidity data were collected. Structural equation modeling was used to test for mediation in the overall sample, and in sex- and age-stratified subsamples, all analyses adjusted for concurrent lifestyle confounds. RESULTS: In the overall sample, ACEs were associated with multimorbidity, directly, ß = 0.12 (95% confidence interval 0.11-0.13) and indirectly. Regarding indirect associations, ACEs were related to social engagement, ß = -0.14 (-0.16 to -0.12) and social engagement was related to multimorbidity, ß = -0.10 (-0.12 to -0.08). ACEs were related to allostatic load, ß = 0.04 (0.03-0.05) and allostatic load was related to multimorbidity, ß = 0.16 (0.15-0.17). The model was significant for males and females and across age cohorts, with qualifications in the oldest stratum (age 75-85). CONCLUSIONS: ACEs are related to multimorbidity, directly and via social engagement and allostatic load. This is the first study to show mediated pathways between early adversity and multimorbidity in adulthood. It provides a platform for understanding multimorbidity as a lifespan dynamic informing the co-occurrence of the varied disease processes represented in multimorbidity.

Trajectories of distress from pregnancy to 15-months post-partum during the COVID-19 pandemic.

Background: The COVID-19 pandemic has particularly burdened pregnant and postpartum women. It remains unclear how distress levels of pregnant and postpartum people have changed (or persisted) as the pandemic continues on and which factors may contribute to these trajectories of distress. Methods: This longitudinal study included 304 pregnant people, who were followed during pregnancy, 6-weeks, 6-months and 15-months postpartum. At each time point, a latent "distress" factor was estimated using self-reported depressive symptoms, anxiety symptoms, and stress. Reported negative impact of COVID-19 and social support were assessed during pregnancy as risk and protective factors related to distress. Second-order latent growth curve modeling with a piecewise growth function was used to estimate initial levels and changes in distress over time. Results: Mean distress was relatively stable from the pregnancy to 6-weeks postpartum and then declined from 6-weeks to 15-months postpartum. Higher education, greater social support, and lower negative impact of COVID-19 were associated with a lower distress during pregnancy. Unexpectedly, negative impact of COVID-19 was associated with a faster decrease in distress and more social support was associated with a greater increase in distress from pregnancy to 6-weeks postpartum. However, these effects became non-significant after controlling for distress during pregnancy. Conclusion: Findings indicate high but declining levels of distress from pregnancy to the postpartum period. Changes in distress are related to social support and the negative impact of the pandemic in pregnancy. Findings highlight the continued impact of COVID-19 on perinatal mental health and the need for support to limit the burden of this pandemic on pregnant people and families.

Positive Parenting and Early Childhood Cognition: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

This review examines the effectiveness of positive parenting interventions aimed at improving sensitivity, responsiveness, and/or non-harsh discipline on children's early cognitive skills, in four meta-analyses addressing general mental abilities, language, executive functioning, and pre-academics. The objectives are to assess the magnitude of intervention effectiveness and identify moderators of effectiveness. We include randomized controlled trials of interventions targeting positive parenting to improve cognition in children < 6 years. Studies that include children with neurodevelopmental and/or hearing disorders were excluded. MEDLINE, PsycINFO, ERIC, and ProQuest Dissertations & Theses (October 2021) and citation chaining identified relevant records. Five reviewers completed screening/assessments, extraction, and risk of bias. Pooled analysis in Comprehensive Meta-Analysis (Version 3) used random effects modeling, with moderation via Q-statistics and meta-regression. Positive parenting interventions led to significant improvements in mental abilities (g = 0.46, N = 5746; k = 33) and language (g = 0.25, N = 6428; k = 30). Effect sizes were smaller and nonsignificant for executive functioning (g = 0.07, N = 3628; k = 14) and pre-academics (g = 0.16, N = 2365; k = 7). Robust moderators emerged for language and cognition. For cognition, studies with higher risk of bias scores yielded larger intervention effects. For language, studies with younger children had larger effect sizes. Studies mitigated selection and detection bias, though greater transparency of reporting is needed. Interventions that promote parental sensitivity, responsiveness, and non-harsh discipline improve early mental abilities and language. Studies examining executive functioning and pre-academics are needed to examine moderators of intervention effectiveness. Trial registration Systematic review PROSPERO registration. CRD42020222143.

Emotion socialization parenting interventions targeting emotional competence in young children: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Although emotion socialization parenting interventions are supported by a growing body of literature, their effects have yet to be systematically examined. The present systematic review and meta-analysis assesses the evidence for emotion socialization parenting interventions for parents of young children. METHODS: Six electronic databases were systematically searched from inception to October 5th, 2022. We conducted random effects meta-analyses of randomized controlled trials of emotion socialization interventions delivered to parents of children aged 18 months to 6 years 11 months. RESULTS: Twenty-six studies which reported data from 15 individual trials met the inclusion criteria. Interventions had a positive effect on positive and negative emotion socialization parenting practices (g's = 0.50) and child emotional competence (g = 0.44). Interventions also had a positive effect on positive (g = 0.74) and negative parenting behaviors (g = 0.25), parent psychological well-being (g = 0.28), and child behavioral adjustment (g = 0.34). Findings remained significant after considering potential publication bias and conducting sensitivity analyses. Two significant moderating factors emerged. CONCLUSIONS: Emotion socialization parenting interventions are effective for improving emotion socialization parenting practices and child emotional competence. Additional methodologically rigorous trials are needed to buttress the current evidence and provide evidence for additional moderating factors.

Associations between psychological distress and hair cortisol during pregnancy and the early postpartum: A meta-analysis.

Pregnancy and the early postpartum signify a period of high stress. Perinatal stress can include psychological distress (PD), such as anxiety, depression, and stress, as well as neuroendocrine stress, indexed by activation of the hypothalamic-pituitary-adrenal (HPA) axis and the production of the hormone cortisol. Elevated PD and cortisol levels during the perinatal period can have long-term implications for the mother and child. Methodological advances have enabled the sampling of cortisol from hair, to provide a retrospective marker of HPA axis activity over several months. Despite knowing that maternal PD and HPA activity during the perinatal period independently impact health and development, research to date is unclear as to the association between maternal PD and hair cortisol. The present meta-analysis included 29 studies to assess the strength of the relation between maternal PD and hair cortisol levels during pregnancy and the early postpartum period. Several sample and methodological factors were assessed as moderators of this effect. Analyses were conducted using multilevel meta-analysis. Results of the multilevel meta-analysis indicated that the overall effect size between PD and HCC was small but not significant z = 0.039, 95% CI [- 0.001, 0.079]. Moderator analyses indicated that the strength of the association between PD and hair cortisol was moderated by pregnancy status (i.e., effects were stronger in pregnant compared to postpartum samples), timing of HCC and PD measurements (i.e., effects were larger when PD was measured before HCC) and geographic location (i.e., effects were larger in North American studies). The findings advance our understanding of the link between PD and HPA activity during the perinatal period, a time of critical impact to child development.

Maternal Childhood Maltreatment History and Child Behavior Problems: Developmental Patterns and Mediation via Maternal Depressive Symptoms and Parenting Behavior.

Maternal exposure to childhood maltreatment (CM) is associated with offspring behavioral problems; however, little work has examined these associations longitudinally across child development. This study examined the effects of maternal history of CM on trajectories of child internalizing and externalizing behavior measured from toddlerhood to preschool, and the role of maternal depressive symptoms and parenting behavior as potential mediators. Participants included 115 mother-child dyads recruited from a hospital maternity ward. Maternal CM was measured at 3-months postpartum. At 18, 36, and 60 months, maternal depressive symptoms and child behavior were assessed via maternal report and parenting behavior was assessed through direct observation. Findings indicated that children of mothers exposed to CM demonstrated poorer trajectories of problem behavior across early childhood. Maternal depressive symptoms mediated the relation between CM and children's internalizing problems. Findings highlight the importance of screening for maternal depressive symptoms and early intervention for maternal and child mental health.

Negative emotionality as a candidate mediating mechanism linking prenatal maternal mood problems and offspring internalizing behaviour.

Negative emotionality (NE) was evaluated as a candidate mechanism linking prenatal maternal affective symptoms and offspring internalizing problems during the preschool/early school age period. The participants were 335 mother-infant dyads from the Maternal Adversity, Vulnerability and Neurodevelopment project. A Confirmatory Bifactor Analysis (CFA) based on self-report measures of prenatal depression and pregnancy-specific anxiety generated a general factor representing overlapping symptoms of prenatal maternal psychopathology and four distinct symptom factors representing pregnancy-specific anxiety, negative affect, anhedonia and somatization. NE was rated by the mother at 18 and 36 months. CFA based on measures of father, mother, child-rated measures and a semistructured interview generated a general internalizing factor representing overlapping symptoms of child internalizing psychopathology accounting for the unique contribution of each informant. Path analyses revealed significant relationships among the general maternal affective psychopathology, the pregnancy- specific anxiety, and the child internalizing factors. Child NE mediated only the relationship between pregnancy-specific anxiety and the child internalizing factors. We highlighted the conditions in which prenatal maternal affective symptoms predicts child internalizing problems emerging early in development, including consideration of different mechanistic pathways for different maternal prenatal symptom presentations and child temperament.

Maternal sensitivity moderates the association between maternal history of childhood maltreatment and child executive function.

BACKGROUND: Experiences of childhood maltreatment are associated with a variety of negative outcomes throughout individuals' lives as well as disadvantaged cognitive and socioemotional development among their offspring. The mechanisms through which some children show resilience against the intergenerational transmission of risk, however, are less well understood. OBJECTIVE: The current study focuses on a proximal parental factor that plays a central role in children's early cognitive development - maternal sensitivity - and examines whether it moderates the association between maternal history of childhood maltreatment and child executive function (EF). PARTICIPANTS AND SETTING: Data were collected from a community sample of 139 mothers and their infants (51 % female) recruited from urban areas in Ontario, Canada. METHODS: Maternal maltreatment history was assessed via self-report at child age 3 months. Maternal sensitivity was assessed observationally at child age 8 months, and child executive function was assessed using performance-based measures at child age 3 years. Hypotheses were tested through multiple regression models. RESULTS: In the current sample, maternal maltreatment history was not associated with child EF on average. However, results were consistent with a moderation model, indicating that maternal maltreatment history was associated with lower levels of child EF only when mothers were relatively insensitive. CONCLUSIONS: The findings indicate the importance of considering sensitive parenting practices as a protective factor for children's cognitive development in the context of more distal risk factors such as mothers' history of childhood maltreatment.

Examining attachment, cortisol secretion, and cognitive neurodevelopment in preschoolers and its predictive value for telomere length at age seven.

Background: Secure attachment reflects caregiver-child relationship in which the caregiver is responsive when support and comforting are needed by the child. This pattern of bond has an important buffering role in the response to stress by the reduction of the negative experience and its associated physiological response. Disruption of the physiological stress system is thought to be a central mechanism by which early care impacts children. Early life stress causes cellular and molecular changes in brain regions associated with cognitive functions that are fundamental for early learning. Methods: The association between attachment, cortisol response before and after the Strange Situation Experiment, and neurodevelopment was examined in a sample of 107 preschoolers at age three. Also, the predictive effect of cortisol reactivity and attachment on telomere length at age seven was investigated in a followed-up sample of 77 children. Results: Children with insecure attachment had higher cortisol secretion and poorer neurodevelopmental skills at age three. A significant cortisol change was observed across the experiment with non-significant interaction with attachment. The attachment and neurodevelopment association was not mediated by cortisol secretion. Preschoolers' attachment and cortisol did not associate nor interacted to predict telomere length at age seven. Conclusion: These findings add evidence to the detrimental effects of insecure attachment as an aggravator of the physiological response to stress and poorer neurodevelopment during the preschool period. Although attachment and cortisol were not predictive of telomere length, intervention policies that promote secure attachment are more likely to positively echo on several health domains.

Replicating patient-level moderators of CBT and IPT's comparative efficacy for depression.

Although evidence-based psychotherapies, such as cognitive behavioral therapy (CBT) and interpersonal psychotherapy (IPT), produce comparable average outcomes, it is plausible that some patients who possess one or more specific characteristics may respond better to one over the other. Addressing this what works best for whom question, researchers have tested the moderating influence of patient characteristics on comparative treatment effects (viz. aptitude-treatment interactions [ATIs]). However, few ATIs have emerged or replicated, thereby providing little treatment-selection guidance. Informed by a systematic review of patient ATIs in trials that compared CBT versus IPT for depression (Bernecker et al., 2017), this study aimed to replicate (a) significant ATIs previously established in a single study; and (b) significant ATIs previously examined twice, with only one study demonstrating a moderating effect. Data derived from a trial in which adult outpatients with major depression were randomly assigned to 16 weeks of CBT (n = 41) or IPT (n = 39). Patient characteristics were measured at baseline, and patients rated their depression throughout treatment. Multilevel models revealed one ATI replication; for patients with more self-sacrificing interpersonal problems, CBT outperformed IPT; the reverse was true for patients with fewer such problems. Other moderators either failed to replicate or directionally contradicted prior research. Results help inform optimal treatment matching for some patients, which reflects a type of psychotherapy personalization. However, they also highlight limitations of traditional ATI research and suggest that different methods are needed to inform responsive personalization efforts more expansively and reliably.

From temperament and parenting to attachment: a review of the interplay of gene and environment factors in the developmental pathway to attachment.

PURPOSE OF REVIEW: Attachment represents an aspect of the parent-child relationship by encapsulating behaviours and stress management strategies. Although attachment is not considered a measure of psychopathology, some attachment styles place children at higher risk for psychopathologies. The origins of attachment have historically thought to be either parenting-related variables, or temperament. More recently, there has been accumulated evidence of gene × environment interactions in attachment, temperament, and parenting. This review aims to cover shared gene × environment pathways between these variables, introduce recent relevant insights from prenatal programming research, and offer a synthesized developmental cascade model of attachment. RECENT FINDINGS: Carriers of gene polymorphisms related to stress neurobiology respond differently to environments than noncarriers according to two patterns: attachment research shows inconsistent diathesis-stress between gene polymorphisms and environment, and temperament, stress physiology, and prenatal programming research show clear patterns of differential susceptibility. SUMMARY: By synthesizing prenatal and postnatal findings, a model of attachment emerges in which individuals more susceptible to environmental influences are carriers of specific genes, whose endophenotypic markers include stress biology and phenotypic markers include temperament. Intervention should, therefore, focus on parenting and stress regulation strategies for these individuals.

Mental Health Help-Seeking in Parents and Trajectories of Depressive and Anxiety Symptoms: Lessons Learned From the Ontario Parent Survey During the COVID-19 Pandemic.

Tracking parents' mental health symptoms and understanding barriers to seeking professional help are critical for determining policies and services to support families' well-being. The COVID-19 pandemic has posed enormous challenges to parents' mental health and the access to professional help, and there are important public health lessons that must be learned from the past 2 years' experiences to inform future mental health responses to social- and family-level stressful events. This study examines the trajectories of parents' depressive and anxiety symptoms over a year during the pandemic as related to their mental health help-seeking. Data were collected from a sample of parents residing in Ontario, Canada at baseline (May-June, 2020; Wave 1) and again 1 year later (Wave 2; referred to as W1 and W2 below). Parents (n = 2,439; M age = 39.47, SD = 6.65; 95.0% females) reported their depressive and anxiety symptoms at both waves. Mental health help-seeking, including self-reported contact with professional help and perceived unmet mental health needs, was measured at W2. Parents were classified into four groups by mental health help-seeking. Inconsistent seekers and non-seeking needers, both reporting perceived unmet needs for professional help, showed greater increases in depressive and anxiety symptoms, whereas parents with no need or needs met showed smaller increases in depressive symptoms and decreases in anxiety symptoms. Belief in self-reliance and time constraints were the leading reasons for not seeking help. These findings suggest that over a year into the pandemic, parents with perceived unmet mental health needs were at greater risk for worsening depressive and anxiety symptoms. Recognizing the demands for mental health services when families experience chronic stressors and targeting the identified barriers may promote family well-being during and beyond this pandemic.
