Examining The Self-Schema Within A Cognitive Vulnerability-Stress Framework Of Mania, Nadia Maiolino
Examining The Self-Schema Within A Cognitive Vulnerability-Stress Framework Of Mania, Nadia Maiolino
Electronic Thesis and Dissertation Repository
This dissertation aimed to inform a cognitive vulnerability-stress theory of mania, which addresses both the content and structure of the self-schema, along with the conditions under which these self-relevant cognitions are activated. Extant research on mania has primarily considered self-schema content, or an individual’s actual beliefs (e.g., “I am incompetent”). Although these investigations have successfully identified maladaptive self-beliefs associated with bipolar disorder, this research has been prone to inconsistencies and limited in distinguishing between mania and related forms of psychopathology (e.g., unipolar depression). Furthermore, very little research on mania has considered the organization of self-schema beliefs, referred to here as …
Child And Adolescent Sleep Disturbances And Psychopathology In A Mental Health Clinic Sample, Aviva Blacher
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 …
Exploring The Links Between Social Anxiety And Depression In The Maintenance Of Romantic Relationships, Christian M. Hahn
Exploring The Links Between Social Anxiety And Depression In The Maintenance Of Romantic Relationships, Christian M. Hahn
Electronic Thesis and Dissertation Repository
Social anxiety is characterized by fear and avoidance of social encounters and has recently been associated with a variety of difficulties in romantic relationships. Complicating further investigation of these associations is the high degree of comorbidity between social anxiety and depressive symptomatology, which share several similarities in expression despite disparate underlying causes. The present thesis examines the unique influences of social anxiety and depression on a number of central aspects of relationship functioning and provide the first longitudinal investigation of the impacts of actor and partner social anxiety and depression on relationship quality and functioning. In Study 1, three independent …
Baseline And Stress-Induced Cognitive Control Deficits And Pro-Inflammatory Cytokines In Currently, Remitted, And Never Depressed Individuals, Katerina Rnic
Electronic Thesis and Dissertation Repository
Background: Cognitive theories posit that cognitive control deficits promote depression by reducing ability to self-regulate under stress. When activated by stress and accessible to working memory, negative cognitive content and structure (i.e., schemas), may interfere with cognitive control abilities, resulting in even greater declines in executive functioning. Moreover, burgeoning evidence indicates that social stress upregulates inflammation, resulting in a pro-inflammatory phenotype that drives depression pathogenesis. However, cognitive mechanisms underlying this process are not well understood. An objective of this study was to examine depression-related deficits in cognitive control and their association with poor self-regulation. Another purpose was to evaluate the …
A Developmental And Symptom-Level Approach To Comorbid Mental Health Disorders In Children, Elizabeth Thornley
A Developmental And Symptom-Level Approach To Comorbid Mental Health Disorders In Children, Elizabeth Thornley
Electronic Thesis and Dissertation Repository
This dissertation addresses current issues in the conceptualization and classification of childhood mental health issues (e.g., impact of sex/age on symptoms, comorbidity, limits of traditional models). In contrast to traditional models, the importance and value of utilizing individual symptoms as primary variables of interest is presented. This first study consisted of 9565 participants (M = 12.06, SD = 3.57, 58% males). Results for youth with no history of trauma indicated sex differences in symptom expression consistent with what has been previously shown in the literature; however, a complex presentation of attention-related symptoms was identified for females. Similar sex differences …
The Role Of Social Disconnection In The Relationship Between Perfectionism And Psychological Distress, Samantha Chen
The Role Of Social Disconnection In The Relationship Between Perfectionism And Psychological Distress, Samantha Chen
Electronic Thesis and Dissertation Repository
This dissertation investigated the interpersonal mechanisms through which various aspects of perfectionism confer risk for psychological outcomes. Three studies were conducted based on the Perfectionism Social Disconnection Model (Hewitt, Flett, & Mikail, 2017), which proposes that individuals with higher levels of perfectionism may experience significant social disconnection, which then lead to a variety of maladaptive outcomes. Study 1 examined the longitudinal impacts of trait perfectionism and sense of relatedness on the variance in change in psychological outcomes. Findings showed that negative perceptions of relatedness partially mediated the link between socially prescribed perfectionism and psychological distress three months later; however, this …
In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber
In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber
Electronic Thesis and Dissertation Repository
In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …
The Role Of Cognitive Distortions In The Longitudinal Relationship Between Problematic Drinking And Depressive Symptoms, Monica F. Tomlinson
The Role Of Cognitive Distortions In The Longitudinal Relationship Between Problematic Drinking And Depressive Symptoms, Monica F. Tomlinson
Electronic Thesis and Dissertation Repository
This dissertation investigated the mechanisms by which problematic drinking contributes to depressive symptoms in two longitudinal, prospective, cohort-design studies. Distorted cognitive processes (dysfunctional attitudes, negatively-biased information processing, and rumination) were proposed as mediators in the relationship between problematic drinking and depressive symptoms over time. Study 1 (N = 1090) assessed participants’ levels of problematic drinking, dysfunctional attitudes, and depressive symptoms at three-month intervals for one year. Findings indicated that the social and occupational consequences of alcohol use (e.g., interpersonal conflict) significantly predicted depressive symptoms. The amount and frequency of alcohol consumption did not. Therefore, impairment, but not level of …
Examining The Relationship Between Intrinsic Drivers Of Motivation And Functional Outcomes In A Cross-Section Of Individuals With Psychotic Disorders, Sahana Kukan
Electronic Thesis and Dissertation Repository
Impaired functioning is recognized as a major barrier to recovery among individuals with psychotic disorders. Research on the role of negative symptomatology on functioning has identified avolition (i.e. lack of motivation) as being highly correlated with functional outcomes. However, current measures of avolition fail to consider more intrinsic factors that influence motivation. There is a need for more nuanced research on the drivers of motivation and their relationship with functioning to inform the observed relationship between avolition and impaired functioning. This cross-sectional study uses data obtained from the Prevention and Early Intervention Program for Psychoses, in London, Ontario. 105 clients …
