Effect of a school-based active play intervention on sedentary time and physical activity in preschool children

Early childhood is a critical time for promoting physical activity. Few studies have investigated the effect of interventions in this population. The aim of this study was to investigate the effect of a school-based active play intervention on preschool children’s sedentary time and physical activity. Preschool children were recruited from randomly selected preschools. Schools were randomly assigned to an intervention or comparison group. One teacher per intervention school received training from active play professionals in the delivery of a 6-week active play programme. Comparison schools continued their usual practice. Children wore a uni-axial accelerometer for 7 days at baseline, immediately after and at 6-month post-intervention. No significant intervention effects were observed for sedentary time or physical activity. However, sex and hours spent at school were significant predictors of physical activity. Children who spent fewer hours (half-day children) at school were significantly more active than their full-day counterparts. Physical activity during the intervention classes was high even though neither daily physical activity nor sedentary time changed. Notably children who spent more time at preschool were less active suggesting that preschool was not as conducive to physical activity engagement as other environments.

Attitudes towards younger and older victims of child sexual assault

The findings of this thesis showed that while mock jury groups perceived older children as less credible, other factors such as lack of evidence and testimony were important considerations in the determination of guilt.

Child weight status: Relationships with mother-child mealtime interactions and child eating behaviours

This doctoral thesis highlighted how mother-child interactions surrounding responsiveness, affect, maternal control and child compliance may be influential to children’s self-regulatory behaviours around food and eating, in turn impacting their weight. Support was found for the potential role of such interactions as risk factors in childhood overweight and obesity.

The effectiveness of the cognitive interview procedure with child witnesses

Two separate studies examined whether the cognitive interview – an interview with embedded mnemonics –enhanced children’s eyewitness accounts. Study 1 found that modifying a mnemonic from a verbal cue to a drawing did not augment memory but protected against suggestive questions. Study 2 found the interview enhanced the coherency of children’s’ account.

The road map to building new dreams : raising a child with developmental delay or disability

Research on early childhood education emphasises the importance of quality in early childhood intervention. This study examines the quality of Early Childhood Intervention Services based on parents’ experiences raising a child with developmental delay or disability. The study builds on the philosophy of Family-Centred Practice and professionals’ experiences with family-centred interventions. A qualitative case study approach was adopted to gain insight about families who are raising a child with additional needs. Nine in-depth parent-interviews and three focus groups with professionals were conducted in the first two terms of 2010. The case explicates the experiences of parents and professionals who were associated with Specialist Children’s Services in a metropolitan region of Victoria. The research concentrated on the first point of entry to early intervention, the referrals process and the waiting list. It also addressed parents' experiences, priorities and expectations. As a small-scale study, it examined parents’ and children’s needs as well as children’s access to therapy in early intervention. It also investigated community support and parent-professional relationships in the context of early childhood intervention services. The study found that family-centred intervention is beneficial to both parents and children with developmental delay or disability. However, to implement an effective family-centred approach, practitioner support in the form of professional development, supervision and peer mentorship is required to develop professionals’ reflexivity and self-efficacy in family-centred interventions. The study also identified strategies to promote effective practice, gaps in universal and specialised services, and implications for policy.

Low health-related quality of life in school-aged children in Tonga, a lower-middle income country in the South Pacific

Background:
Ensuring a good life for all parts of the population, including children, is high on the public health agenda in most countries around the world. Information about children’s perception of their health-related quality of life (HRQoL) and its socio-demographic distribution is, however, limited and almost exclusively reliant on data from Western higher income countries.

Objectives:
To investigate HRQoL in schoolchildren in Tonga, a lower income South Pacific Island country, and to compare this to HRQoL of children in other countries, including Tongan children living in New Zealand, a high-income country in the same region.

Design:
A cross-sectional study from Tonga addressing all secondary schoolchildren (11–18 years old) on the outer island of Vava’u and in three districts of the main island of Tongatapu (2,164 participants). A comparison group drawn from the literature comprised children in 18 higher income and one lower income country (Fiji). A specific New Zealand comparison group involved all children of Tongan descendent at six South Auckland secondary schools (830 participants). HRQoL was assessed by the self-report Pediatric Quality of Life Inventory 4.0.

Results:
HRQoL in Tonga was overall similar in girls and boys, but somewhat lower in children below 15 years of age. The children in Tonga experienced lower HRQoL than the children in all of the 19 comparison countries, with a large difference between children in Tonga and the higher income countries (Cohen’s d 1.0) and a small difference between Tonga and the lower income country Fiji (Cohen’s d 0.3). The children in Tonga also experienced lower HRQoL than Tongan children living in New Zealand (Cohen’s d 0.6).

Conclusion:
The results reveal worrisome low HRQoL in children in Tonga and point towards a potential general pattern of low HRQoL in children living in lower income countries, or, alternatively, in the South Pacific Island countries.

Explaining the gender differences inperceptions of child sexual abuse

The aim of the thesis was to understand how gender, empathy and myth endorsement impact on jurors' perceptions of child sexual abuse victims.

Improving the evidential quality of child witness statements about sexual abuse

 Child sexual abuse cases are often not prosecuted because of poor evidential quality of the visually recorded investigative interview. This thesis examined prosecutors’ perceptions of interviews and took a constructive approach to determine how the evidential quality and usefulness of interviews could be improved.

Exploring children’s work involvement and school attendance in rural Cambodia

This thesis is entitled: Exploring children’s work involvement and school attendance in rural Cambodia. The author identified that children’s participation in education is heavily influenced by family financial strain, limited school and community engagement, risks of school dropout for unskilled work opportunities and the failure of education leading to employment.

Determinants of school attendance among migrant children: survey evidence from China's Jiangsu province

Across the developing world education is seen as a means of raising levels of everyday wellbeing and is being linked to improved measures of productivity and economic growth. This paper employs a household production function framework to examine the determinants of school attendance among migrant children using a unique dataset collected in China's Jiangsu province. The study finds that the main predictors of school attendance among migrant children in the sample were household income, mother's education, the length of residence of the child's mother in the city and whether both parents were working in the same city. © 2006 Blackwell Publishing Ltd.

The efficacy of a brief behavioral sleep intervention in school-aged children with ADHD and comorbid autism spectrum disorder

Sleep problems are common in children with autism spectrum disorders (ASD) and ADHD and impact adversely on child and parent well-being. The study evaluated the efficacy of a brief behavioral sleep intervention in children with comorbid ADHD-ASD.

Systematic research review of observational approaches used to evaluate mother-child mealtime interactions during preschool years.

The family meal and social interactions during the meal are important events in a child's life. Specifically, mealtime interactions have been linked to child weight status, the development of children's eating patterns, and socialization. Mealtime interactions may be observed and evaluated to provide insights into this important event beyond self-reported measurements.
