A Systematic Review of Neurodevelopmental Assessments in Infancy and Early Childhood: Developing a Conceptual Framework, Repository of Measures, and Clinical Recommendations.

The first 6 years of life are when 90% of brain development occurs, setting the foundation for lifelong neurodevelopment. The field of infant and early childhood neurodevelopment has made marginal advancements since introduced in 1988. There remains a gap in knowledge around early neurodevelopmental domains and trajectories given that there are few established assessment procedures for infants and young children and controversies around reserving assessments until school age. Throughout this systematic review, we (1) identified neurodevelopmental assessment measures employed in the literature by domain and age of assessment, (2) compiled a repository of 608 domain-specific neurodevelopmental assessment measures, and (3) established a preliminary conceptual framework for cross-domain neurodevelopmental assessments across infancy and early childhood. This review adhered to PRISMA guidelines and spanned three databases (PsycINFO, MEDLINE, PubMed). Articles were reviewed for (1) infancy and early childhood (0-6 years), (2) neurodevelopmental measures, and (3) English language. This systematic review spanned 795 articles from 1978 to 2020 with international representation. Advancements in assessment methods (e.g. measures, domains, frameworks) are essential for the evaluation of early neurodevelopmental profiles to inform early interventions, thus harnessing the neuroplasticity and dynamic development notable during early childhood. We hope this work catalyzes future research and clinical guidelines around early assessments methods.

A systematic review of callous-unemotional traits and attachment in children and adolescents.

METHODS: The systematic review and meta-analysis included 17 research articles from 1994 to 2022. Results were summarized by developmental periods. RESULTS: Attachment insecurity was associated with CU traits across development (r = .17). This association was marginally stronger for high-risk samples (e.g., clinical, justice) and for continuous attachment measures versus coding schemes. From early to middle childhood, attachment disorganization was associated with CU traits (r = .17). IMPLICATIONS: Research on attachment and CU traits in childhood is still in its infancy. Changes in attachment measures from childhood to adolescence make developmental comparisons difficult. Results suggest attachment as a potential developmental mechanism for youth with CU traits, however, the area requires more research.

A dyadic perspective on aggressive behavior between friends.

Youth are sometimes victimized by their friends, but we know little about the nature of these relationships. Taking a dyadic approach, we studied relationships characterized by both friendship and aggression. Participants (952 middle schoolers; 50% female; 44% Latinx) nominated friends and aggressive perpetrators and victims. Using two analytic samples of friend dyads (N = 6971) and aggressive dyads (N = 4662), results indicated that aggression by a friend was somewhat common. Compared with friend dyads without aggression, aggressive friend dyads were stronger (i.e., reciprocal) and longer lasting, though victimized youth were less satisfied with the friendship. Aggressive dyads who were friends more often had reciprocal aggression than aggressive dyads who were not friends. Results provide insight into the dynamics of aggression in close peer relationships.

School bullying before and during COVID-19: Results from a population-based randomized design.

We examined the impact of COVID-19 on bullying prevalence rates in a sample of 6578 Canadian students in Grades 4 to 12. To account for school changes associated with the pandemic, students were randomized at the school level into two conditions: (1) the pre-COVID-19 condition, assessing bullying prevalence rates retrospectively before the pandemic, and (2) the current condition, assessing rates during the pandemic. Results indicated that students reported far higher rates of bullying involvement before the pandemic than during the pandemic across all forms of bullying (general, physical, verbal, and social), except for cyber bullying, where differences in rates were less pronounced. Despite anti-Asian rhetoric during the pandemic, no difference was found between East Asian Canadian and White students on bullying victimization. Finally, our validity checks largely confirmed previous published patterns in both conditions: (1) girls were more likely to report being bullied than boys, (2) boys were more likely to report bullying others than girls, (3) elementary school students reported higher bullying involvement than secondary school students, and (4) gender diverse and LGTBQ + students reported being bullied at higher rates than students who identified as gender binary or heterosexual. These results highlight that the pandemic may have mitigated bullying rates, prompting the need to consider retaining some of the educational reforms used to reduce the spread of the virus that could foster caring interpersonal relationships at school such as reduced class sizes, increased supervision, and blended learning.

The Mediational Effect of Affect Dysregulation on the Association Between Attachment to Parents and Oppositional Defiant Disorder Symptoms in Adolescents.

Oppositional defiant disorder (ODD) is a childhood disorder, commonly occurring in early school aged children with some symptoms becoming normative in adolescence (e.g., irritability, disagreeing). Affect dysregulation is a risk factor in the development of ODD. Affect regulation is nurtured within parent-child relationships, thus disruptions to attachment may derail children's capacity to develop adaptive affect regulation, increasing the risk for ODD. Using a high-risk sample of adolescents, we investigated the association between attachment anxiety and attachment avoidance with ODD through affect dysregulation. Attachment anxiety, but not avoidance, was associated with affect dysregulation and ODD. Affect dysregulation was found to fully mediate the relationship between attachment anxiety and ODD concurrently and prospectively. Similar findings have been demonstrated among children; results show that attachment anxiety, and its effects on affect dysregulation, are associated with ODD symptoms well into adolescence.

ADHD and Exposure to Maltreatment in Children and Youth: a Systematic Review of the Past 10 Years.

PURPOSE OF THE REVIEW: The purpose of the current paper was to review and summarize the literature on ADHD and maltreatment over the past 10 years. RECENT FINDINGS: The majority of research on ADHD and exposure to maltreatment focuses on the high rates of comorbidity, including international studies from Asia, South America, North America, and Europe. Longitudinal studies showed that early exposure to maltreatment is a risk factor for ADHD symptoms later in development; however, this finding was not consistent. There were some preliminary studies on the neurological and genetic mechanisms underlying the link between ADHD and exposure to maltreatment. Finally, ADHD and exposure to maltreatment were found to have an additive effect on clinically salient outcomes (e.g., aggression, suicide attempts). Results from the review have direct clinical and future implications, including the need to understand the effect of comorbid ADHD and exposure to maltreatment in treatment studies.

Trauma-informed and relational approaches to service provision: building community-based project capacity to respond to interpersonal violence through a national initiative.

BACKGROUND: Community services that engage and service marginalized families can act as an important entry point for mothers and children experiencing interpersonal violence. The purpose of this study was to use an initiative that included training, implementation, and evaluation of an interpersonal violence intervention to understand changes in the capacity of service providers in community-based organizations to use trauma-informed and relational approaches to support mothers and children experiencing violence in relationships. METHODS: Participants (N = 27) were service providers from 14 community-based organizations across Canada, who had been trained to implement an interpersonal violence intervention with mothers in their communities. Using a phenomenological approach, participants engaged in an open-ended interview in which they were encouraged to reflect on their experiences in the intervention initiative, with prompts relating to the ways in which their work and their organization may have changed as a result of their participation. RESULTS: Findings indicated that participants were able to identify changes in four key areas related to trauma-informed practice: awareness (e.g., attitudes toward interpersonal violence), competency (e.g., application of trauma-informed knowledge), collaboration (e.g., working with other organizations to provide services to children and families), and safety (e.g., organizational policies to ensure safe, welcoming spaces). Further, participants identified these areas of change at the level of themselves as facilitators of the interpersonal violence intervention, their organizations, and their communities. CONCLUSIONS: Results indicate that, through training, implementation, and evaluation of an interpersonal violence intervention, service providers in community-based projects were able to extend trauma-informed and relational principles not only to the intervention itself, but also to their own work, as well as that of their organizations and communities. With some additional support, leveraging the existing capacities within community-based projects may be an effective means to support mothers and children experiencing interpersonal violence and other challenges.

Peer victimization through a trauma lens: Identifying who is at risk for negative outcomes.

Peer victimization is a chronic stressor that occurs within the context of peer interactions and has been robustly associated with numerous negative psychological and social adjustment problems. Although increased frequency of peer victimization has been linked to psychosocial problems, few researchers have studied the role of duration and pervasiveness of victimization (i.e., number of places it occurs). The objective of this study was to examine how frequency, duration, and pervasiveness of peer victimization are associated with youth adjustment. Canadian adolescents (N = 879), ages 12-18 completed an online survey about experiences with peer victimization. Youth also answered questions about internalizing problems, distress, relationship quality with family, friends, and adults in their school and community, as well as academic functioning. Data were analyzed using multinomial logistic regression modeling. Both duration and pervasiveness of peer victimization were predictive of increased internalizing problems, distress, relationship problems, and academic difficulties. Duration and pervasiveness of peer victimization were identified as important factors to consider when predicting youth psychosocial adjustment. By asking questions about these situational factors, parents, teachers, and healthcare providers may more effectively identify youth who are at risk for experiencing mental health problems associated with peer victimization.

Developing and testing a readiness tool for interpersonal violence prevention partnerships with community-based projects.

Community-based projects that serve vulnerable families have the opportunity to identify and respond to interpersonal violence (IPV). We developed a readiness assessment tool to support selection of projects to participate in an initiative that involved implementing a community-based IPV intervention for mothers. The overarching aim of the current study was to describe the development of this tool and examine the reliability of coding, validity, and utility of the tool. After developing and refining the tool, 41 community-based projects completed the tool. Responses were coded and scored; scores were used to select projects for the initiative. Preliminary validation for the tool included (a) expert opinion, (b) uptake/implementation of the intervention, and (c) feedback and responses from service providers in terms of the usefulness and importance of the tool. This tool can be used by both researchers and service providers to assess community project readiness and capacity to provide trauma-informed services for vulnerable families.

Internalizing symptoms and dating violence perpetration in adolescence.

BACKGROUND: Increasing evidence suggests an association between internalizing symptoms and violence against others. It remains unknown whether this link exists in the context of romantic relationships. In the current study, we tested whether anxiety and depression were associated over time with adolescent dating violence perpetration. METHODS: The sample included 238 Canadian adolescents (42% boys). Using a longitudinal design, their anxiety, depressive symptoms, and dating violence perpetration were annually assessed from age 14 to 15 years. RESULTS: Cross-lagged analyses revealed effects from anxiety and depressive symptoms to dating violence one year later (ß = 0.27, p < .001; and ß = 0.14, p = .04, respectively). No reversed cross-lagged paths were found from dating violence to subsequent anxiety or depression. CONCLUSIONS: Our findings underscore the predictive value of internalizing symptoms on dating violence perpetration. Reducing internalizing symptoms and improving coping strategies are important targets for the prevention of dating violence.

A comparative effectiveness study of the breaking the cycle and Maxxine Wright intervention programs for substance-involved mothers and their children: study protocol.

BACKGROUND: Children of substance-involved mothers are at especially high risk for exposure to adverse childhood experiences (ACEs) and poor mental health and development. Early interventions that support mothers, children, and the mother-child relationship have the greatest potential to reduce exposure to early adversity and the mental health problems associated with these exposures. Currently, there is a lack of evidence from the real-world setting demonstrating effectiveness and return on investment for intervention programs that focus on the mother-child relationship in children of substance-involved mothers. METHODS: One hundred substance-involved pregnant and/or parenting women with children between the ages of 0-6 years old will be recruited through the Breaking the Cycle and Maxxine Wright intervention programs, in Toronto, Ontario, Canada and Surrey, British Columbia, Canada, respectively. Children's socioemotional development and exposure to risk and protective factors, mothers' mental health and history of ACEs, and mother-child relationship quality will be assessed in both intervention programs. Assessments will occur at three time points: pre-intervention, 12-, and 24-months after engagement in the intervention program. DISCUSSION: There is a pressing need to identify interventions that promote the mental health of infants and young children exposed to early adversity. Bringing together an inter-disciplinary research team and community partners, this study aligns with national strategies to establish strong evidence for infant mental health interventions that reduce child exposure to ACEs and support the mother-child relationship. This study was registered with clinicaltrials.gov (NCT05768815) on March 14, 2023.

Developmental trajectories of romantic stages and associations with problem behaviours during adolescence.

Normative romantic development is theorized to progress through a series of stages: affiliative activities, group-based dating, and romantic relationships. The objectives of this research were threefold: empirically examine this progression of romantic stages during adolescence, determine normative and atypical trajectories, and examine links with internalizing and externalizing symptoms. An eight-wave longitudinal study was conducted with 698 adolescents (53.6% female; M(age) = 11.8 years at start of study). A group-based trajectory approach was employed to identify prototypical trajectories of romantic development and a model with three distinct romantic trajectories (i.e., On-time, Early Starters and Late Bloomers) was identified. Both timing and sequencing of romantic activity differed among trajectory groups. Analysis of Variance (ANOVAs) identified associations between Early Starters and externalizing behaviours in early, middle and later adolescence. The findings support progression through theorized stages of romantic activity and highlight the problems that are linked to early-starting and non-sequenced romantic development.

Bullying before and during the COVID-19 pandemic.

The rates of bullying during the COVID-19 pandemic, a time of unprecedented public health and social restrictions, were compared to earlier times when students attended school in person. Several studies indicated a notable decrease in the prevalence of bullying victimization and perpetration during the pandemic, particularly when online learning was implemented. But studies from countries with fewer social restrictions indicated increases in rates of bullying during the pandemic. Mixed results regarding prevalence rates for some bullying forms (e.g., cyberbullying) were also found. Racialized youth and LGBTQ+ youth reliably reported higher rates of bullying victimization during the pandemic, consistent with pre-pandemic patterns. Reasons for the inconsistencies in findings likely relate to diverse methods, timeframes, and sampling techniques, as well as different experiences with pandemic social restrictions. More longitudinal studies are needed to assess whether bullying involvement did in fact "change" during, compared to before, the pandemic. The findings point to the importance of peer relationships and hint at the potential of increased teacher supervision as a bullying prevention strategy.

Adherence to and Motivations for Complying With Public Health Measures Among Adolescents During the Coronavirus Disease (COVID-19) Pandemic in Canada.

Background: Public health measures (e.g., minimizing social interactions, social distancing, and mask wearing) have been implemented in Canada to reduce the transmission of COVID-19. Given that adolescents may be a high-risk demographic for spreading COVID-19, this study investigated adherence to and motivations for complying with public health measures among Canadian youth at two points of the COVID-19 pandemic. Methods: Adolescents (N = 1,484, 53% girls, Mage = 15.73 [SD = 1.41]) completed an online survey in either Summer 2020 (Cohort 1 [C1]; n = 809, 56% girls) or Winter 2020/2021 (Cohort 2 [C2]; n = 675, 50% girls). We investigated differences in adherence across cohorts using independent sample t-tests and predictors of adherence using a path analysis. Results: Youth engaged in similar levels of social interaction in C1 and C2. Relative to adolescents in C1, adolescents in C2 reported more mask wearing, but less social distancing. Social responsibility was associated with adherence to almost all public health measures across both cohorts, with one exception: it did not predict minimizing social interactions in C2. Not wanting to get sick predicted minimizing social interactions and mask wearing. Concern with population health predicted adherence to all public health measures in C1 and all but mask wearing in C2. Maintaining social ties was negatively associated with minimizing social interactions in both cohorts, and with social distancing in C1. Conclusions: Youth engaged in more mask wearing but less social distancing as the pandemic progressed. Social responsibility and not wanting to get sick were consistent predictors of adherence to most public health measures throughout the pandemic. Youth shifted away from adhering to mask wearing measures due to concern with population health over the course of the pandemic. These results can inform targeted campaigns to bolster compliance with public health measures among adolescents.

Bullying: a stepping stone to dating aggression?

Bullying is the use of power and aggression to control and distress another. In this paper, we review research to explore whether the lessons learned in bullying provide a stepping stone to aggressive behavior in dating relationships. We start by considering definitions and a relationship framework with which to understand both bullying and dating aggression. We consider bullying from a developmental-contextual perspective and consider risk factors associated with the typical developmental patterns for bullying and dating aggression, including developmental and sociodemographic, individual attributes, and family, peer group, community, and societal relationship contexts that might lead some children and youths to follow developmental pathways that lead to bullying and dating aggression. We conclude by discussing implications for intervention with a review of evidence-based interventions.

A characteristic destabilization profile in parent-child interactions associated with treatment efficacy for aggressive children.

This study examined profiles of change in repeated mother-child interactions over the course of a 12 week treatment period for childhood aggression. The aim of this study was to investigate whether it was possible to detect the characteristic profile of change, typical for phase transitions, over the course of treatment, and whether this profile was associated with positive treatment outcomes. Entropy values were computed for six repeated real-time observations of each mother-child dyad, using a novel application of recurrence quantification analysis for categorical time series. Subsequent latent class growth curve analysis on the sequences of entropy values revealed two distinct classes of dyads, with one class showing a clear peak in entropy over the six measurement points. The latent class membership variables showed a significant systematic relationship with observed dyad improvement (as rated by clinicians). The class with the peak in entropy over the sessions consisted largely of treatment improvers. Further analysis revealed that improvers and non-improvers could not be distinguished based on content-specific changes (e.g. more positivity or less negativity during the interaction). The present study revealed a treatment-related destabilization pattern in real-time behaviors that was related to better treatment outcomes, and underlines the value of dynamic nonlinear time-series analysis (especially RQA) in the study of dyadic interactions in clinical contexts.

Why Worry about Bullying?

In this article, the authors review research to identify bullying as a critical public health issue for Canada. Drawing from recent World Health Organization surveys, they examine the prevalence of Canadian children and youth involved in bullying others or being victimized. There is a strong association between involvement in bullying and health problems for children who bully, those who are victimized and those involved in both bullying and being victimized. Health problems can manifest as physical complaints (e.g., headaches), mental health concerns (e.g., depression, anxiety) and psychosocial problems (e.g., substance use, crime). In Canada, there has recently been a disturbing incidence of Canadian children who have committed suicide as a result of prolonged victimization by peers. Healthcare professionals play a major role in protecting and promoting the health and well-being of Canadian children and youth. Given the significant mental and physical health problems associated with involvement in bullying, it is important that clinicians, especially primary care healthcare professionals, be able to identify signs and symptoms of such involvement. Healthcare professionals can play an essential role supporting children and their parents and advocating for the safety and protection for those at risk. By understanding bullying as a destructive relationship problem that significantly impacts physical and mental health, healthcare professionals can play a major role in promoting healthy relationships and healthy development for all Canadian children and youth. This review provides an overview of the nature of bullying and the physical and psychological health problems associated with involvement in bullying. The review is followed by a discussion of the implications for health professionals and a protocol for assessing the potential link between bullying and a child's physical and psychological symptoms.

Looking Beyond Assumptions to Understand Relationship Dynamics in Bullying.

To account for the complex relationships and processes that constitute the phenomenon of bullying, it is critical to understand how students and their parents and teachers conceptualize traditional and cyberbullying. Qualitative data were drawn from a mixed methods longitudinal study on cyberbullying. Semi-structured interviews were held with Canadian students in grades 4, 7, and 10 in a large urban school board, and their parents and teachers. To account for the complexity and interactions of different systems of relationships, the purpose of the current article is to examine how students and their matched parents and teachers understand traditional and cyberbullying. Central to participants' understanding of traditional and cyberbullying was whether they considered bullying to represent harmful relationship dynamics. Three main assumptions emerged as shaping participants' understanding of bullying and appeared to obscure the deep relationship processes in bullying: (a) assumptions of gender in bullying, (b) type of bullying-comparing traditional and cyberbullying, and (c) physical bullying as disconnected from relationship dynamics. It is essential that assessment, education, and prevention and intervention strategies in traditional and cyberbullying be informed by the inherent relationships in bullying and be implemented at multiple levels of relationships and broader social systems.

A national implementation of a community-based intervention for mothers experiencing violence in relationships.

Interpersonal violence is a significant concern for families; thus interventions to support vulnerable mothers and children experiencing violence are essential. The purpose of this study was to present preliminary evaluation results from the national dissemination of an interpersonal violence intervention for mothers delivered in community-based programs across Canada. In 18 communities, 184 mothers participated in the intervention. Mothers reported on measures related to the self, relationships, parenting, and knowledge of community services, both before and after the intervention. Mothers comprised a high-risk, vulnerable population. Results indicated feasibility and acceptability, based on a high proportion of intervention completers and high levels of satisfaction. Women reported improvements in self-esteem, self-efficacy, relationship capacity, parenting stress, knowledge of community services, and understanding of relevant concepts compared to before the intervention (with small to medium effects). Additional analyses supported some of these findings as particularly robust. We discuss the importance of community-based projects in reaching diverse families, sustaining engagement with high levels of satisfaction, and supporting mothers in making changes relating to themselves, their relationships, and their parenting.

Cumulative Risk, Protection, and Early Intervention: Neurodevelopment in Sibling Groups Exposed Prenatally to Substances.

Mothercraft's Breaking the Cycle is an early intervention program for substance-exposed children with neurodevelopmental vulnerabilities. Within three substance-exposed sibling groups (N = 8; 0-6 years), we 1) described longitudinal neurodevelopmental trajectories, 2) explored the balance of cross-domain cumulative risk and protection on neurodevelopment, and 3) generated hypotheses on how cumulative risk, protection, and early intervention impact neurodevelopment. Neurodevelopment is potentially shaped by the balance of risk and protection. Postnatal risk (birth/postnatal, child, parent-child interaction) and relational protection (family, parent-child interaction) appear to have the most salient impact on neurodevelopment. Early intervention is thought to be important as soon as possible and before age 3 years.
