This Viewpoint discusses the role of childhood developmental stage in research evaluating the effects of screen use among youth and its application to practice, policy, and the public.

Exposure to adverse childhood experiences (ACEs), including maltreatment and family dysfunction, is a major contributor to the global burden of disease and disability. With a large body of international literature on ACEs having emerged over the past 25 years, it is timely to now synthetize the available evidence to estimate the global prevalence o...

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 c...

Background: Adverse childhood experiences (ACEs) can be associated with negative health outcomes such as substance use. However, extant literature assessing this association is mixed. Objective: The present meta-analysis was conducted to obtain a pooled effect size for the association between ACEs and substance use (i.e., smoking, problematic al...

An individual participant data meta-analysis was conducted to test pre-registered hypotheses about how the configuration of attachment relationships to mothers and fathers predicts children's language competence. Data from seven studies (published between 1985 and 2014) including 719 children (Mage : 19.84 months; 51% female; 87% White) were includ...

This scoping review aimed to address the following questions: (1) Does mild traumatic brain injury (mTBI) result in more parental distress or poorer family functioning than other injuries?; (2) Does pre-injury or acute parental distress and family functioning predict post-concussive symptoms (PCS) after mTBI?; and (3) Do acute PCS predict later par...

Longitudinal changes in maternal depressive and anxiety symptoms and predictors of symptom variation among a group of middle-to-upper income Canadian women (n = 2152) were examined prior to the pandemic (2017-2019) and at three pandemic timepoints (May-July 2020, March-April 2021, November-December 2021). Mean maternal depression and anxiety scores...

Background: Exposure to sexual content, such as online pornography or live sexual content, has been posited in the literature as a risk factor for problematic sexual behaviors (PSBs) in children and adolescents, and has been identified as an important avenue for research and intervention, particularly given the ubiquitous access to technology amon...

Based on interviews with leading researchers and researcher-clinicians in fields allied to attachment research, this paper describes participants’ perceptions of contemporary attachment research in the developmental tradition.

This article presents a strategy for the initial step of data harmonization in Individual Participant Data syntheses, i.e., making decisions as to which measures operationalize the constructs of interest - and which do not. This step is vital in the process of data harmonization, because a study can only be as good as its measures. If the construct...

Although numerous individual studies have attempted to link child-parent attachment and prosociality, a systematic picture of that relation requires a meta-analytic approach that considers different dimensions of prosociality and potential moderators. The current meta-analysis examined 41 studies drawn primarily from North America and Europe and pu...

Meta‐analytic associations between observed parental sensitivity and child behavioral problems were examined (children aged 0–17 years). Studies (k = 108, N = 28,114) contained sociodemographically diverse samples, primarily from North America and Europe, reporting on parent‐child dyads (95% mothers; 54% boys). Sensitivity significantly related to...

Past research has demonstrated that romantic attachment insecurity is a risk factor for dating violence in adolescence. However, few studies to date have longitudinally examined whether earlier relational experience, such as perceived closeness with parents, may serve as an antecedent of this relationship. To examine longitudinal associations among...

Importance: Pediatric guidelines suggest that infants younger than 2 years avoid screen time altogether, while children aged 2 to 5 years receive no more than 1 hour per day. Although these guidelines have been adopted around the world, substantial variability exists in adherence to the guidelines, and precise estimates are needed to inform public...

La théorie et les recherches sur l’attachement sont utilisées dans de nombreux cadres d’application, y compris dans les tribunaux compétents en matière familiale [1], mais les incompréhensions sont fréquentes et sources d’erreurs lorsqu’il s’agit de les mettre en pratique. L’objectif de cet article de consensus est donc d’accroître la compréhension...

Children exposed to child sexual abuse (CSA) vary considerably with regards to their presenting concerns and treatment needs. One factor creating heterogeneity amongst children experiencing CSA is their history of experiencing other victimizations (i.e., poly-victimized or not). However, little is known about risk factors for poly-victimization as...

An unsettled question in attachment theory and research is the extent to which children's attachment patterns with mothers and fathers jointly predict developmental outcomes. In this study, we used individual participant data (IPD) meta-analysis to assess whether early attachment networks with mothers and fathers are associated with children's inte...

Socio-demographic risks are associated with higher child screen time and higher screen time is associated with poor socioemotional and developmental health. Existing studies have not examined children’s screen time as a mechanism through which distal risks may be associated with child outcomes. In the current study, we examined whether two proximal...

Objective: Research suggests that children's screen use during the COVID-19 pandemic has doubled. There is a need to understand factors associated with increased use to more adequately inform COVID-19 pandemic recovery efforts aimed at promoting healthy device habits. The objective of this multi-informant study of children aged 9 to 11 years was t...

A meta-analysis of 39 studies (110,380 participants) from 2009 to 2015 indicated that youth sexting increased over time. To inform current practice and policy initiatives, this meta-analytic update of studies since 2016 examined if rates of youth sexting have continued to rise and whether youth sexting differs by age, sex, sexting methods, and geog...

Background: There has been an increase in use of trauma-informed care (TIC) approaches, which can include screening for maternal Adverse Childhood Experiences (ACEs) during prenatal care. However, there is a paucity of research showing that TIC approaches are associated with improvements in maternal or offspring health outcomes. Using retrospectiv...

In Reply We appreciate the response to our systematic review and meta-analysis in JAMA Pediatrics¹ suggesting that, in addition to a near doubling in clinically elevated depressive and anxiety symptoms in children and adolescents during the COVID-19 pandemic, there have been increases in other mental health concerns, including eating disorders (EDs...

There is now a growing understanding that translational research must be co-created in collaboration with community partners and that solutions to real-world social problems require stepping outside the academic silo. Fewer than half of psychology programs in Canada, however, offer courses in community-based research or evaluation, leaving a gap in...

Objectives: Adverse childhood experiences (ACEs; i.e., exposure to abuse, neglect, household dysfunction in childhood) are associated with poor mental and physical health outcomes across the lifespan. Emerging research suggests parent ACEs also confer risk for poor child outcomes. The relation between parent ACEs and child pain in youth with chron...

Background Adverse childhood experiences (ACEs), including abuse, neglect, and/or household dysfunction, are associated with physical and mental health difficulties in pregnancy and the postpartum period. These associations have prompted the adoption of screening for ACEs in prenatal care settings; however, little is known about whether asking abou...

Background Mothers have experienced a near doubling of depression and anxiety symptoms pre- to during the COVID-19 pandemic. The identification of mechanisms that account for this increase can help inform specific targets for mental health recovery efforts. The current study examined whether women with higher levels of depression and anxiety sympto...

Demarcating childhood into two distinct and broad 10-year age bands of over and under age 10 is a disservice to our tween population (9–12 years), and may be overlooking our role in understanding the negative impacts of SARS-CoV-2 (COVID-19) during a formative period of development. In this commentary, we discuss the importance of considering tween...

This meta‐analysis tested maternal responsivity as a mediator of the association between socioeconomic risk and children's preschool language abilities.
