A Study Of Multiple Predictors Of Cognitive Fatigue In Individuals With Multiple Sclerosis, Leila M. Mackay Jul 2019

A Study Of Multiple Predictors Of Cognitive Fatigue In Individuals With Multiple Sclerosis, Leila M. Mackay

Electronic Thesis and Dissertation Repository

Persons with multiple sclerosis (PwMS) commonly experience cognitive fatigue (CF), defined as a decrease in cognitive performance over a sustained activity and measured objectively or subjectively. In the present research, we evaluated the extent to which depression, anxiety, information processing speed, sleep quality, and disease severity predict subjective and objective CF, in a sample of 55 PwMS (37 females, M = 44.23). Although no statistically significant predictors of objective CF were demonstrated, all variables predicted subjective CF, R2adj = .384 [F (6, 40) = 5.783, p = .0002]. In particular, depression and information processing speed were found to be significant predictors of ...


Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs Aug 2018

Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs

Electronic Thesis and Dissertation Repository

Exercise improves anxiety and depression, both of which are associated with impaired autonomic regulation of heart rate (HR). In turn, HR variability (HRV) is a reliable physiological indicator of external stressors. The following research tested the hypothesis that HRV is indicative of chronic resilience towards mental stress in female varsity hockey players. Seventeen varsity hockey players (HOCK, age 21 ± 1.5) and fifteen healthy controls (CTRL, age 21 ± 2.2) at Western University participated three times throughout a 7-month season. Participants completed questionnaires (brief resilience scale, BRS; generalized anxiety scale, GAD-7; mental health inventory, MHI; visual analog scale, VAS; short ...


Does Self-Regulation Mediate The Relationship Between Locus Of Control And Resiliency Related Outcomes?, Alexander J. Mcgregor Jul 2018

Does Self-Regulation Mediate The Relationship Between Locus Of Control And Resiliency Related Outcomes?, Alexander J. Mcgregor

Electronic Thesis and Dissertation Repository

Locus of control has been implicated in predicting mental wellbeing outcomes in a variety of theories and empirical studies, however the mediating mechanisms between the trait and mental wellbeing are not well known. The king and Rothstein (2010) model of resiliency posits self-regulation as the active mechanism that leads to recovery in resiliency related outcomes following significant adversity. These self-regulatory processes are predicted by a series of related traits, such as self-efficacy, neuroticism, or conscientiousness. This study investigated the mediating role of affective, behavioral, and cognitive self-regulation between locus of control, depression, and anxiety using mediation analysis. The results indicated ...


The Relationship Between Different Dating Violence Profiles, Mental Health Problems And Mental Well-Being Among Canadian Youth, Kelsey E. Macdonald Apr 2016

The Relationship Between Different Dating Violence Profiles, Mental Health Problems And Mental Well-Being Among Canadian Youth, Kelsey E. Macdonald

Electronic Thesis and Dissertation Repository

The current study examined the relationships among teen dating violence, mental health problems and mental well-being in 338 adolescents aged 14-21 (54% female). Secondary data were retrieved from an evaluation of a small groups healthy relationship program. Participants were grouped into four different dating violence profiles based on self-reported perpetration and victimization: not involved, perpetrators, victims and combined. Generalized Linear Models were used to examine the similarities and differences across types on depression, anxiety, mental well-being and binge drinking. Results suggested that the victims and combined profiles experienced greater mental health problems and decreased mental well-being compared to other profiles ...


Biological And Contextual Predictors Of The Stability Of Behavioural Inhibition In Early Childhood, Victoria C. Johnson Aug 2015

Biological And Contextual Predictors Of The Stability Of Behavioural Inhibition In Early Childhood, Victoria C. Johnson

Electronic Thesis and Dissertation Repository

Persistently elevated behavioural inhibition (BI) in children confers increased risk for anxiety disorders. However, little research has jointly examined exogenous and endogenous factors that may moderate BI stability in early childhood. To explore whether parent (i.e., parental overinvolvement, parent anxiety) and child (i.e., 5-HTTLPR and BDNF val66met genotype, positive emotionality) factors influenced the stability of early BI, a community sample of 371 preschoolers and their caregivers completed observational measures of child temperament, observational and questionnaire measures of parenting, and parent interviews for anxiety disorder history. Child BI at age 3 interacted with children’s 5-HTTLPR variants to predict ...


The Transdiagnostic Prevention Of Emotional Disorders: A Randomized Controlled Study, Rebecca Mcdermott Jun 2015

The Transdiagnostic Prevention Of Emotional Disorders: A Randomized Controlled Study, Rebecca Mcdermott

Electronic Thesis and Dissertation Repository

Major Depression and anxiety disorders are prevalent, costly, and comorbid disorders. These emotional disorders also share some vulnerability factors, making them good candidates for transdiagnostic or simultaneous prevention. The current study is a double-blind, primary prevention study that focuses on preventing emotional disorders in at risk, first and second year undergraduate students. Three internet-delivered preventative programs were compared: a Cognitive Behavioural Therapy (CBT) intervention (MoodGYM), an attentional bias modification program (Dandeneau & Baldwin, 2004), and an active attentional control. Participants (n = 354) completed symptom measurement pre- and post- a six-week intervention and again at a four-month follow-up, when they were also ...


Agoraphobia And Emptiness: Theoretical Considerations From A Psychoanalytic Perspective, Sheena L. Yates Mar 2015

Agoraphobia And Emptiness: Theoretical Considerations From A Psychoanalytic Perspective, Sheena L. Yates

Electronic Thesis and Dissertation Repository

Milrod (2007) identifies persistent emptiness in agoraphobia patients whose symptoms of anxiety and avoidance have remitted. Through an analysis of the available theoretical and clinical literature on agoraphobia, the psychological experience of emptiness, and the development of the ego, I argue that agoraphobia is not an anxiety about “open spaces” but, rather, about the boundaries between spaces. In agoraphobia, there is a pathological persistence of the psychological processes of normal ego development. Recognition of the usefulness of agoraphobic anxieties in the development of ego boundaries may help to identify the point at which they persist beyond usefulness and into pathology ...


Childhood Abuse And Neglect: A Profile Of Associated Risk Factors For Non-Suicidal Self-Injury, Jennifer P. Gomez Mar 2014

Childhood Abuse And Neglect: A Profile Of Associated Risk Factors For Non-Suicidal Self-Injury, Jennifer P. Gomez

Electronic Thesis and Dissertation Repository

Non-suicidal self-injury (NSSI) is the intentional destruction of body tissue without suicidal intent and for purposes not socially sanctioned. Approximately 14 to 17% of nonclinical adolescent populationss and over 40% of clinical adolescent populations use NSSI to cope. NSSI is consistently related to childhood maltreatment and the objective of this study was to examine differences between maltreated individuals who do and do not self-injure. Groups were compared on risk factors of childhood maltreatment and self-injury with the intent of creating a risk profile for NSSI. Participants who had experienced abuse/neglect scored higher on depression than a contrast group, regardless ...


The Effects Of Neonatal Immune System Activation With Lipopolysaccharide On Adolescent And Adult Anxiety Behaviours In Male And Female Rats, Alina Zaltzman Jul 2012

The Effects Of Neonatal Immune System Activation With Lipopolysaccharide On Adolescent And Adult Anxiety Behaviours In Male And Female Rats, Alina Zaltzman

Electronic Thesis and Dissertation Repository

The present study examined the effects of neonatal (postnatal days 3 and 5) acute immune system activation with lipopolysaccharide (LPS) on adolescent and adult anxiety behaviours. The major findings suggest that neonatal LPS does not have general long-lasting effects on adolescent anxiety and locomotor behaviours. Rather, early endotoxin treatment has highly specific effects on certain anxiety behaviours that vary depending on the development period. Moreover, neonatal LPS does not seem to influence adult voluntary and non-voluntary locomotor activity or anhedonia, independent of, or in response to, an adult immune challenge. Finally, sex differences were observed in various responses in adulthood ...


Individual Differences In Temperament And Cognitive Biases In Middle Childhood: Vulnerability To Internalizing Psychopathology, Patricia L. Jordan May 2012

Individual Differences In Temperament And Cognitive Biases In Middle Childhood: Vulnerability To Internalizing Psychopathology, Patricia L. Jordan

Electronic Thesis and Dissertation Repository

A multi-trait multi-method study was conducted exploring associations between individual differences in child temperament and cognitive vulnerability for depression and anxiety. Two-hundred and five 7-year-old children and their parents participated. Low positive emotionality and high negative emotionality predicted a depressogenic attributional style as well as attentional biases for positive and sad stimuli. Individual differences in child fearfulness were also associated with attentional biases to threat-related information. Associations between child cognitive vulnerability and parental history of depression and anxiety were also explored, as well as associations between child internalizing symptoms and (1) child temperament and (2) cognitive vulnerability. Paternal, but not ...
