The Developmental Importance Of Napping In Preschool Children, Adam T. Newton

Electronic Thesis and Dissertation Repository

Most children cease napping between 2- and 5-years-old. Little is known about the predictors or outcomes related to this cessation, or the interrelation of different components of nap behavior. Four empirical studies were conducted to investigate the developmental importance of napping among preschool children.

Studies 1 and 2 used a large, longitudinal sample of Canadian children to investigate the predictors (Study 1) and outcomes (Study 2) related to early nap cessation. Early nap cessation was defined as stopping daytime sleep before three years old. In Study 1, parents reported on their own, child, and family functioning at two timepoints (0-1 …

Using Spoken Narratives To Measure Listening Engagement In Children, Sarah Bobbitt

Electronic Thesis and Dissertation Repository

Despite the rising popularity of audiobooks and podcasts, research on children listening to spoken stories remains in its infancy. In addition, the use of spoken stories could significantly improve studies of listening engagement in children. Thus, the present study sought to 1) explore how children aged 8-13 years engage with these novel media and 2) determine which stories might be most engaging to children in this age group. Fifty-two parents of children aged 8-13 years completed an online survey which asked about their children’s listening habits. Results of the survey then informed the development of four engaging stories (and two …

The Relationship Between Neighbourhood-Level And Family-Level Factors And Sleep Problems Among Children And Youth, Katarina Mckenzie

Electronic Thesis and Dissertation Repository

There is little research on the effects of neighbourhood factors on child sleep outcomes. No study to date has investigated the interactive effects of neighbourhood and family socio-economic characteristics (SECs) on child sleep outcomes. This study aimed to fill this gap. Secondary data analyses were completed on two samples (children and youth) from the 2014 Ontario Child Health Study, a cross-sectional, province-wide sample of 10,802 children aged 4 to 17. Multi-level modeling was used to assess the relationship between child- (e.g., age), family- (e.g., negative parenting) and neighbourhood-level factors and their relationship to sleep outcome variables: problems falling asleep, problems …

Validating An Observational Coding System For The Dominance Behavioural System (Dbs) In Childhood, Jennifer Mullen

Electronic Thesis and Dissertation Repository

The dominance behavioural system (DBS) is a biologically based system that underpins individual differences in motivation for dominance and power. However, little is known about the DBS in childhood. In a pilot study aimed at developing a behavioural coding system for dominance, a key facet of the DBS, we collected and coded observational data from 58 children, assessed at ages 3 and 5-6. Between these ages, dominance was moderately stable, to a degree comparable to other early child temperament traits. Consistent with study hypotheses, boys were more dominant than girls, and dominance was negatively associated with children’s behavioural inhibition, effortful …

Understanding Service Gaps And Support Opportunities In The Treatment Of Childhood Anxiety, Chelsey R. Masson

Electronic Thesis and Dissertation Repository

Globally, anxiety disorders represent the most prevalent mental health disorders in children and youth (Polanczyk et al., 2015), with an increasing number of individuals perceiving the need for professional help (Georgiades et al., 2019). It is unclear, however, where families are seeking help from, what barriers families are facing, and what services are being provided for effective management of symptoms. Two methods were used to investigate possible treatment support models; a questionnaire identified patterns in parental help-seeking behaviours and outlined perceived barriers to professional help, while a scoping review examined key components of parent/caregiver treatment models. Findings showed that parents …

Exploring Teachers’ Perspectives On Child Anxiety: Opportunities To Promote Anxiety Management Skills In The Classroom, Sydney Coleman

Electronic Thesis and Dissertation Repository

The purpose of the current study was to examine how teachers identify and provide supports for students with anxiety as well as their perspectives on implementing strategies informed from cognitive behavioural therapy (CBT) in the classroom. Data was collected from 11 classroom teachers in London, Ontario through virtual focus group sessions and an online demographic questionnaire. Thematic analysis revealed three key themes: opportunities to implement CBT-informed strategies, barriers to implementing CBT-informed strategies, and current knowledge and resources. The findings revealed that teachers perceived that they are facing increased demands to support the mental health needs of students without appropriate resources …

The M3 curriculum includes mindful awareness concepts, social emotional learning, neuroscience and positive psychology. Ninety-seven children between the ages of 3-10-years and their parents participated in the M3 program. Children completed a mindfulness knowledge questionnaire pre and post-intervention and their responses to prompting questions related to using the skills at home were recorded. Parents completed the Behaviour Rating Inventory of Executive Functioning pre and post-intervention to investigate the efficacy of …

Neither Seen Nor Heard: Surviving Children Of Domestic Homicide, Alexis Winfield

Electronic Thesis and Dissertation Repository

Domestic homicide is a critical human rights issue that continues to impact women, children, and families in Canada. Between 2010-2018, 662 individuals died as a result of domestic homicide, many of whom were mothers who left surviving children behind. This study examined the experiences of surviving children prior to, during, and in the aftermath of domestic homicide through quantitative and qualitative court and media document analyses. It was found that 136 children in Ontario experienced domestic homicide between 2010-2017. Domestic homicide impacted surviving children in all domains of functioning and was often associated with long-term adverse outcomes. Court documents revealed …

Individual Differences In Executive Functioning And Psycho-Emotional Well-Being And The Impact Of Acute Exercise On Children And Youth With Adhd, Madeline Crichton

Electronic Thesis and Dissertation Repository

Short bouts of exercise can improve inhibitory control in children with Attention Deficit Hyperactivity Disorder (ADHD). However, individual differences among children with ADHD may impact the effectiveness of exercise interventions. We investigated how individual differences in inhibitory control, mood, and self-efficacy impact the efficacy of acute exercise among children with ADHD. Sixteen participants (ages 10-14) completed two interventions: 10 minutes of exercise and 10 minutes of silent reading (control). Inhibitory control was assessed prior to the intervention, immediately after the intervention, and after a 10-minute delay. Results suggested that participants with lower initial inhibitory control benefited more from exercise than …

Children’S Perspectives On The Social Exclusion Of Peers With Behavioural Difficulties, Kayla Edwards

Electronic Thesis and Dissertation Repository

Children who display externalizing behaviours are more likely than their peers to experience social exclusion. To better examine this topic, the perspectives of peers were investigated. Thirty-six participants were interviewed from a school in Southwestern Ontario. Participants were asked why they believe children with behavioural difficulties may be socially excluded by peers. Unique statements were extracted from the transcribed data. Participants were invited back to sort the statements into meaningful categories. Sorted data were analyzed using multi-dimensional scaling and cluster analysis. A five-cluster solution was selected as the best conceptual and statistical fit for the data. The clusters in this …

The Psychosocial Functioning Of Children With Chronic Health Conditions: A Meta-Analysis, Serena Thompson

Electronic Thesis and Dissertation Repository

Chronic health conditions are highly prevalent among childhood populations and lead to restrictions in everyday life. Previous research indicates that children and youth with a chronic health condition are at an elevated risk of psychosocial difficulties, including mental illness and social exclusion, compared to typically developing populations. Therefore, the purpose of this study was to determine the impact of chronic health conditions on psychosocial factors during childhood by comparing the psychosocial functioning of children with chronic health conditions and children without chronic illnesses using a meta-analysis. Specifically, three elements of psychosocial functioning were examined, (a) social-emotional functioning, (b) behavioural functioning, …

Child And Adolescent Sleep Disturbances And Psychopathology In A Mental Health Clinic Sample, Aviva Blacher

Electronic Thesis and Dissertation Repository

Sleep disturbances in children and adolescents (hereafter children) are associated with significant short-term and long-term impairments including more severe psychopathology, reduced cognitive functioning, and poorer general health. We know that children being treated in specialty mental health services are more likely to have sleep disturbances than community samples. We also know that relationships exist between sleep and psychopathology in children with specific disorders (e.g. ADHD, depression, etc.). However, few studies have investigated the relationship between sleep and psychopathology in a broad sample of children seen at mental health agencies. Both child factors and family factors may influence both sleep and …

Police Prevention Of Domestic Homicide: Missed Opportunities And Barriers To Change, Michael D. Saxton

Electronic Thesis and Dissertation Repository

This integrated-article dissertation focused on the critical role of police in responding to domestic violence (DV) and recognizing the potential risk of adult and child homicides. The first study examined the police role in domestic homicide through an analysis of cases reviewed by the Domestic Violence Death Review Committee in Ontario, Canada. Homicide cases with police contact were found to have 1.6 times more risk factors compared to those without police contact. Cases also show an overall scarcity of formal risk assessments, even when there was prior police contact. The second study was a national survey on the types of …

Missed Opportunities For Saving Children From Domestic Homicide: Implications For Prevention, Intervention, & Community Collaboration, Katherine Reif

Electronic Thesis and Dissertation Repository

This dissertation is comprised of three studies that explored the risks faced by children exposed to domestic violence, as well as systemic and agency-related recognition of, and responses to, these risks. Literature in the field has demonstrated that children living in these circumstances are at risk of significant adverse outcomes stemming from their exposure to domestic violence, and at its extreme, domestic homicides (Alisic et al., 2017; Jenney & Alaggia, 2014). In addition, these children are also at risk of becoming homicide victims in the context of domestic violence, either through being directly targeted in the homicide, or as a …

Examining Child Sex As A Moderator Of The Relationship Between Cortisol Reactivity And Symptoms Over Time, Andrew R. Daoust

Electronic Thesis and Dissertation Repository

Females’ reactivity to stress appears to be closely tied to internalizing symptoms, while males who are under-reactive may be at risk for externalizing problems. Little is known about when such differences emerge, despite possible implications for early prevention. Cortisol reactivity to a laboratory stressor was assessed in 409 three-year-old children along with children’s parent-reported internalizing and externalizing symptoms, which were re-collected at child ages 5 and 8. Multilevel modelling was used to investigate whether the relationship between cortisol reactivity and symptoms differed between boys and girls longitudinally. Over time, girls with lower cortisol reactivity showed a decrease in depressive symptoms …

Predictors Of Re-Accessing Mental Health Services For Children And Adolescents, Catalina Sarmiento

Electronic Thesis and Dissertation Repository

The natural history of mental health disorders suggests that a substantial number of children experience persistent or recurrent problems and may need more than 1 episode of care. However, there is a paucity of research on recurrent service use. The present study examined the rates and predictors of re-accessing community-based care. Secondary data analyses were conducted on administrative and chart review data from 5 mental health agencies in southwest, eastern, and central Ontario. Approximately a third (30%) of children who had an episode of care re-accessed services again within 4 years; the median time to re-access was 13 months. Social …

Parental Help-Seeking For Pediatric Insomnia: Where, When, And Why Do Parents Seek Help?, Adam T. Newton

Electronic Thesis and Dissertation Repository

Pediatric insomnia affects approximately 25% of children and can impact both child and parent functioning. Despite its prevalence and impact, next-to-nothing is known about help-seeking mechanism for pediatric insomnia. These mechanisms are expected to mirror models from the children’s mental health help-seeking literature. Both studies in this thesis gathered data from an online multinational project. Manuscript 1 investigated the informal, informational, and formal sources of help for pediatric insomnia and the factors that motivated parents to seek professional help. Parents utilized or expected to utilize a variety of informal (most commonly their partner, friends, or family members) and informational (most …

An Extension Of The Dimensional Comparison Theory: A Test Of Emotional Intelligence Self-Concepts., Caitlin J. Spencer

Electronic Thesis and Dissertation Repository

According to the Dimensional Comparison Theory (DCT), individuals’ self-concepts of abilities are influenced not only by external sources of evaluation within the same domain, but also internal comparisons of abilities across different domains, resulting in negative contrast effects for self-concepts in dissimilar domains and positive assimilation effects for self-concepts in similar domains. These dimensional comparisons have been primarily tested with academic domains to date, yet social-emotional learning is an important complement to academic learning. The present study sought to extend the DCT to Emotional Intelligence (EI) self-concepts in a sample of 1,069 Canadian children and adolescents, aged 9-18 years. Using …

Protective Factors And The Role Of Gender In Childhood Mental Health: Application Of The Interrai Assessment Protocol, Alexandria Lynch

Electronic Thesis and Dissertation Repository

The present study examined how a child’s mental health is impacted by protective factors and his/her gender. Resiliency research has been growing in recent years as researchers recognize the value of focusing on strengths in individuals. Previous research has shown that certain protective factors help buffer against the negative effects of mental health disorders differently for males and females. The present study sought to explore this further. The participants were children and youth with severe mental health and behavioural challenges and were drawn from a tertiary care facility and other mental health organizations. The results revealed that the children and …

Exploring Communication Apprehension And Its Relationship To Communication Attitude And Socio-Communicative Functioning In Children With Velopharyngeal Insufficiency, Agnieszka Dzioba

Electronic Thesis and Dissertation Repository

Myriad findings on children with velopharyngeal insufficiency (VPI) indicate the potential for this population of children to experience feelings of apprehension specific to communication and the potential for other psychological and social difficulties. The purpose of the present investigation was to explore the construct of communication apprehension (CA) and its potential relationship to social and communicative functioning in a diverse group of children with VPI. Potential linkages between CA and multiple socio-communicative constructs including attitude, speech satisfaction, speech and language skill, social competence, and speech severity were explored in a cohort of children with and without VPI, followed by an …

Children's Voices In A School-Based Mental Health Needs Assessment, Shannon Byrne

Electronic Thesis and Dissertation Repository

As a part of a larger community mental health needs assessment, grade four students’ experiences of emotions related to mental health constructs were examined using photovoice methodology. Descriptive statistics from a large-scale survey were included to add context to the findings. The overall purpose of the study aimed to: (a) inform the school-based mental healthcare initiative that will be implemented in the school of the participants, and (b) add to the literature regarding children’s self-reported experiences of emotions. Photovoice allowed participants to visually represent their experiences and engage in dialogue about emotions linked to mental health and illness. Discussion questions …

Mental Health And Safety In Schools: Children’S Perceptions And Experiences, Larissa K. Pipe

Electronic Thesis and Dissertation Repository

The current study employed an exploratory analysis of children’s perceptions of safety, mental health and experiences with bullying in school. Secondary data from surveys administered to a Southwestern Ontario school board was used to gather frequency data in addition to exploring the associations between mental health, feelings of safety and experiences with bullying. Furthermore, a photovoice component was administered in a select school, intended to gain a deeper understanding of what leads children to feel safe and unsafe, while in school. Results highlight the number of children experiencing mental health concerns as well as the importance of support systems for …

Children's Mental Health, Yvonne A. Asare-Bediako

Electronic Thesis and Dissertation Repository

The study of children’s mental health has largely been the domain of developmental psychologists and psychiatrists. These studies focus on parental mental health, and examine its direct and indirect effects, through a family’s psychosocial environment. Relatively little attention is given to socio-structural factors. By contrast, the sociology of mental health focuses on such structural factors as poverty and income, examining the extent to which stressors and strains may pattern the effects of these factors on children’s psychopathology. Adding to the divergence in research is the use of maternal reports in the assessment of children’s mental health. These reports often reflect …

An Investigation Of The Association Between Arithmetic Achievement And Symbolic And Nonsymbolic Magnitude Processing In 5-9 Year-Old Children: Evidence From A Paper-And-Pencil Test, Nadia Nosworthy

Electronic Thesis and Dissertation Repository

Recently, there has been a growing emphasis on basic number processing competencies (such as the ability to judge which of two numbers is larger) and their role in predicting individual differences in school-relevant math achievement. Children’s ability to compare both symbolic (e.g. Arabic numerals) and nonsymbolic (e.g. dot arrays) magnitudes has been found to correlate with their math achievement. The available evidence, however, has focused on computerized paradigms, which may not always be suitable for universal, quick application in the classroom. Furthermore, it is currently unclear whether both symbolic and nonsymbolic magnitude comparison are related to children’s performance on tests …

Children's Understanding And Experience Of Anger Within Their Peer Groups, Nicole J. Hamel

Electronic Thesis and Dissertation Repository

The purpose of this study was to describe how children understand, experience and express their anger with others in their peer group, from their perspectives. Semi-structured focus groups were conducted with third grade students in an elementary school. Children were asked three questions: 1) What did you learn about dealing with anger this week? 2) What are some good/positive things that happened between you and your classmates this week? 3) What are some not so good or negative things that happened between you and your classmates this week? Six themes emerged from analysis of the transcripts of the semi-structured focus …

Cognitive, Emotional, And Behavioural Correlates In Children With Psychopathic Traits, Vanessa Leanne Pedden

Electronic Thesis and Dissertation Repository

Psychopathy is a developmental disorder characterized by deficits in emotional, interpersonal, and behavioural domains. Adult psychopaths commit a disproportionate amount of violent crime and are at a heightened risk for recidivism. Research suggests that children with psychopathic traits present with deficits similar to their adult counterparts on measures of passive avoidance learning and emotional processing. There is also evidence to suggest that these children engage in differential forms of aggression. In addition, research suggests that adult psychopathy develops early in life. The purpose of this dissertation was to examine cognitive, emotional and behavioural characteristics in children with psychopathic traits. The …

Development Of A Cohesion Inventory For Children's Sport Teams, Luc J. Martin

Electronic Thesis and Dissertation Repository

The general purpose of this dissertation was to develop an inventory designed to measure cohesion in children’s (ages 9-12) sport teams. To this end, three studies were conducted. In Study 1, children became active agents in the process of test construction. More specifically, children (N = 167) participated in focus groups and completed open-ended questionnaires in order to provide information on their perceptions of cohesion as well as motives for participating, continuing, and ceasing involvement on sport teams. Study 2 involved the use of the information obtained from Study 1 to develop potential items for the questionnaire. In addition, the …

The Importance Of Self-Efficacy And Basic Psychological Needs In Children’S Physical Activity: Measurement, Prediction And Intervention, Casey E. Gray

Electronic Thesis and Dissertation Repository

The importance of physical activity in the overall health promotion and primary prevention of cardiovascular disease risk factors and metabolic diseases in children is well established. Nonetheless, interventions to increase physical activity among this population have been largely unsuccessful. The main objective of the research in this dissertation was to explore the suitability of self-efficacy and basic psychological needs for physical activity prediction and intervention in children. Item generation and psychometric evaluation of psychological questionnaires occurred in study 1 (Chapter 2). Using a prospective design, study 2 (Chapter 3) established task efficacy, barriers efficacy, competence, and autonomy as significant predictors …
