Anxiety In Children And Adolescents With Autism Spectrum Disorder: Behavioural Phenotypes And Environmental Factors, Caitlin E. Leachman Miss

Electronic Thesis and Dissertation Repository

Anxiety is the most prevalent comorbidity among children and adolescents with autism spectrum disorder (ASD). The phenotypical presentation of anxiety among children and adolescents with ASD is lacking within the literature. This study sought to differentiate behavioral phenotypes associated with anxiety in children with ASD from anxiety in typically-developing children. Participants completed a series of child and parent reports measuring anxiety, depressive symptoms, ASD symptom severity, emotional problems, parental stress, and socioeconomic factors. Three distinct anxiety profiles, including moderate, high, and low, were identified. Results demonstrated that depression is the strongest predictor of high anxiety among children and adolescents with …

A Multi-Method Assessment Of The Impact Of Stress On Families’ Mental Health During The Covid-19 Pandemic, Andrew R. Daoust

Electronic Thesis and Dissertation Repository

The COVID-19 pandemic was a pervasive disaster, creating stress for people across the globe. As such, understanding how pandemic-related stress has impacted individuals’ mental health is vital for guiding intervention programs and limiting the impact of future similar crises. This is especially true for youth, who are at heightened risk for mental disorder and may experience pandemic-related social stress as particularly aversive, given the developmental challenges unique to this period. Although substantial efforts have been made to measure the impact of the pandemic-related stress on individuals’ mental health, the pandemic’s relatively sudden onset has limited researchers’ abilities to conduct fulsome …

Socialization Of Depressive Symptoms In Pre- And Early Adolescent Peer Cliques, Suzanne L. Seah

Electronic Thesis and Dissertation Repository

This study examined socialization of depressive symptoms in pre- and early adolescent peer cliques, and clique characteristics (clique gender and friendship density) that may moderate the contribution of clique depression to the prediction of youths’ depressive symptoms over time. Social cognitive mapping identified 162 peer cliques involving 999 youths from Grades 4 through 8 (M age = 11.84; SD = 1.52) in Southwestern Ontario. As expected, multi-level modeling revealed that clique depressive symptoms in fall contributed significantly to the prediction of youths’ depressive symptoms in spring. Null findings regarding clique friendship density and gender as moderators of clique depression …

Examining Associations Between Mothers' Early Adversity, Depression And Maternal Sensitivity, Rossana Bisceglia, Greg Moran, Jennifer Jenkins

Psychology Presentations

This study tested two models for the indirect influence of mothers’ early adversity on maternal sensitivity:

Model A:

• Mothers’ appraisal of infant temperament was hypothesized to mediate the influence of mothers’ early adversity and depression on maternal sensitivity
• There would be no direct influence of maternal depression

Model B:

• Mothers’ depression was hypothesized to have a direct influence on maternal sensitivity
• Mothers’ perception of infant temperament would not mediate the influence of maternal depression on maternal sensitivity
