Cognitive Schemas As Longitudinal Predictors Of Depressive Relapse/Recurrence In An Undergraduate Population, Daniel Machado

Electronic Thesis and Dissertation Repository

Abstract

This study assessed longitudinally the predictors of relapse/recurrence in major depressive disorder, as well as future depressive symptomatology, by examining how people organize information and beliefs about the self and how this changes over time. A secondary objective was to assess the long-term stability of self-schema structures. A sample of undergraduate students completed a computer-based task assessing schema structure, as well as two measures of schema content at baseline, and three and six-month intervals. Analyses for relapse/recurrence yielded insignificant results. However, as predicted, social cognitive distortions at Time 1 and schema structure for negative interpersonal content at Time 1 …

Defining And Predicting Dropout From Children’S Mental Health Services: A Novel Need-Based Definition Of Dropout, Kimberly Williams Dossett

Electronic Thesis and Dissertation Repository

Background: Dropout from children’s mental health services has negative impacts on children, families and community mental health agencies. In order to reduce dropout, it is essential to correctly define individuals as treatment dropouts, and understand the predictors of dropout. Methods: Manuscript 1 describes the development of a novel need-based definition of dropout and contrasts this definition to existing definitions of dropout in the literature. Manuscript 2 uses the need-based definition to examine predictors of dropout, and compares predictors of dropout using different definitions of dropout. Results: The need-based definition categorizes individuals differently from existing definitions of dropout. Caregiver needs are …

The Relationship Between Executive Dysfunction And Criminality In Forensic Psychiatric And Correctional Populations, Erin J. Shumlich

Electronic Thesis and Dissertation Repository

Crime has immense social and economic impact. Understanding and treating the underlying factors of criminal behavior is essential to creating an overall safer society. Deficits in executive functioning — inhibition, cognitive shifting, and working memory — have been implicated as a factor contributing to criminal behavior. Method: Manuscript 1 examines the relationship between executive dysfunction and severity and frequency of criminal behavior of forensic psychiatric patients, individuals who committed crime under the influence of a severe mental disorder. Manuscript 2 compares the executive functioning of two unique criminal populations — forensic psychiatric patients and correctional offenders. Results: Poorer executive functioning …

The Nature And Structure Of Temperament In Early And Middle Childhood: A Multi-Method Approach, Yuliya Kotelnikova

Electronic Thesis and Dissertation Repository

Structural work on the nature of child temperament has lagged far behind parallel research with adults. Further, the structure of extant parent-report questionnaires has been examined only at the higher-order level, using small samples of children. This dissertation addresses this important gap in three studies, examining the lower- and higher-order structure of two widely used parent-reports of child temperament (Studies 1 and 2) and an observational battery of temperament (Study 3). The first study examined the lower- and higher-order structure of the Children’s Behavior Questionnaire (CBQ; Rothbart, Ahadi, Hershey, & Fisher, 2001) in a large community sample of children at …

Examining Internalizing Symptoms In Child And Youth Victims Of Emotional Abuse And Bullying: The Mediating Effects Of Individual And Family Strength Factors In Clinical Samples, Amani M. Elrofaie

Electronic Thesis and Dissertation Repository

Child and youth experiences of emotional abuse and bullying are harmful interactions by caregivers and peers, which produce adverse mental health and social outcomes (Glaser, 2011). This study examined the relationships between trauma exposure and internalizing outcomes through individual and parenting level strength factors. The study comprised 1,297 child and youth participants, aged 4 to 18, from inpatient and outpatient mental health facilities across Ontario, who were administered the interRAI Child and Youth Mental Health assessment (ChYMH; Stewart, Hirdes et al., 2015) with their parents/caregivers. Generalized linear modelling (Nelder & Wedderburn, 1972) was used to determine the relationships between trauma …

An Examination Of Risk Factors For Adolescent Engagement In Directly And Indirectly Self-Injurious Behaviours, Janell A. Klassen

Electronic Thesis and Dissertation Repository

Research identifying similar and dissimilar risk factors for directly and indirectly self-injurious behaviours among adolescents is scarce. Due to the wide range of physical and mental health difficulties that may result from self-injurious behaviours, understanding differential risks is important to support at-risk adolescents. To address this gap in the literature, 541 clinically referred children and youth (ages 11-18 years old) were assessed using the interRAI Child and Youth Mental Health Assessment (ChYMH) and Adolescent Supplement. Logistic regression analyses revealed that older adolescents were at an increased risk for both direct and indirect self-injury. Moreover, adolescents who experienced high levels of …

Aggression Among Children And Youth: An Examination Of Service Allocation For Subtypes Of Aggression, Kari-Ann Clow

Electronic Thesis and Dissertation Repository

To date, there is a paucity of research examining service utilization in relation to aggression in youth, particularly when addressing the typologies of reactive and proactive aggression. This study aimed to determine how subtypes of aggression (reactive, proactive or comorbid) present for service allocation and cost. Participants consisted of 1283 youth receiving care in the province of Ontario, Canada. Bivariate and multivariate analyses using logistic regression were used. Results revealed significant associations between age and aggression type with service utilization. In particular, service complexity was most present for those with comorbid aggression. Those who were identified as reactive were significantly …
