Early childhood education quality and child development in Lao PDR

Globally, as scale up of early childhood education (ECE) continues, monitoring ECE quality is imperative to promote service aspects that drive positive outcomes for children. Monitoring of ECE quality in low- and middle-income countries (LMICs) is scarce, limited by challenges in varied conceptualisations of quality, lack of measurement tools that reflect local culture and context, and implementation difficulties in low resource settings.

Screen Time and Parent-Child Talk When Children Are Aged 12 to 36 Months

Growing up in a language-rich home environment is important for children's language development in the early years. The concept of "technoference" (technology-based interference) suggests that screen time may be interfering with opportunities for talk and interactions between parent and child; however, limited longitudinal evidence exists exploring this association. 

Mental health profiles and academic achievement in Australian school students

This study explored mental health profiles in Australian school students using indicators of well-being (i.e., optimism, life satisfaction, and happiness) and psychological distress (i.e., sadness and worries). The sample included 75,757 students (ages 8-18 years) who completed the 2019 South Australian Wellbeing and Engagement Collection.

This study addresses a knowledge gap in the literature about early adolescent cyberbullying victimization and the related positive and negative emotional wellbeing and academic achievement outcomes experienced over time. 

Clustering of Wellbeing, Engagement and Academic Outcomes in Australian Primary Schools

The mental health and wellbeing of young people has important consequences for students and society. Schools are a logical environment for management and early intervention of wellbeing, mental health and engagement with school. Interventions aimed at improving mental health and wellbeing in education systems requires knowledge of how wellbeing is clustered at a school level. Cluster-randomised trials, and regression analyses of such data also require knowledge of clustering.

The Relationship Between Traditional and Cyber Bullying Victimization in Early Adolescence and Emotional Wellbeing: A Cross-Sectional, Population-Based Study

Despite the wealth of knowledge about the impact of bullying victimization, information gaps exist about how traditional and cyber bullying in early adolescence is associated with emotional wellbeing, namely, indicators of positive wellbeing.

Prevalence of breakfast skipping among children and adolescents: a cross-sectional population level study

Interventions to promote breakfast consumption are a popular strategy to address early life inequalities. It is important to understand the epidemiology of children and adolescents who skip breakfast so that interventions and policy can be appropriately considered.

Research on the consequences of breakfast skipping among students tends to focus on academic outcomes, rather than student wellbeing or engagement at school. This study investigated the association between breakfast skipping and cognitive and emotional aspects of school engagement.

Basic epidemiology of wellbeing among children and adolescents: A cross-sectional population level study

Wellbeing and mental health are fundamental rights of children and adolescents essential for sustainable development. Understanding the epidemiology of child and adolescent wellbeing is essential to informing population health approaches to improving wellbeing and preventing mental illness.

Data Resource Profile: The South Australian Well-being and Engagement Collection (WEC)

Mental health and well-being during childhood and adolescence have been shown to impact on health, educational attainment and employment in adulthood.1–3 Although health and education systems worldwide have long recognized the importance of promoting student well-being,4–6 population-wide monitoring of well-being remains uncommon.

The Impact of Bullying Victimization in Early Adolescence on Subsequent Psychosocial and Academic Outcomes across the Adolescent Period: A Systematic Review

Bullying is a widespread global issue, with serious consequences for victimized individuals. The current systematic review is the first to explore the consequences of bullying in early adolescence on psychological and academic functioning across the adolescent period. Five databases were examined, yielding 28 relevant studies.

Inequalities in child development at school entry: A repeated cross-sectional analysis of the Australian Early Development Census 2009-2018

Australia is the only developed country to consistently undertake a developmental census of its children nationwide. The repeated collection of the Australian Early Development Census (AEDC) has provided an unprecedented opportunity to examine the prevalence of developmental vulnerability across Australia's states and territories, the socio-economic distribution of developmental vulnerability across jurisdictions, and how these distributions might have changed over time.

The role of social support in differentiating trajectories of adolescent depressed mood

This study explored the extent to which disaggregated support from family, peers, close friendships, teachers, and schools predicted membership into identified, sex-specific trajectories of depressed mood in 3210 Australian adolescents (49% females) based on self-report data collected at four annual time points from school Grade 6 to 9 (ages 10–16).

Associations between School Readiness and Student Wellbeing: A Six-Year Follow Up Study

It is well established that children’s school readiness is associated with their later academic achievement, but less is known about whether school readiness is also associated with other measures of school success, such as students’ social and emotional wellbeing. While some previous research has shown a link between early social and emotional development and student wellbeing, results are mixed and the strength of these relationships vary depending on whether data is based on child, teachers or parents ratings and which specific student wellbeing outcomes are measured.

Measuring early child development in low and middle income countries: Investigating the validity of the early Human Capability Index

Inclusion of early child development in the United Nations Sustainable Development Agenda raises issues of how this goal should be monitored, particularly in low resource settings. The aim of this paper was to explore the validity of the early Human Capability Index (eHCI); a population measure designed to capture the holistic development of children aged 3-5 years. Convergent, divergent, discriminant and concurrent validity were examined by exploring the associations between eHCI domains and child (sex, age, stunting status, preschool attendance) and family (maternal education, home learning environment) characteristics. Analyses were repeated using data from seven low and middle income countries.
