Death Of The Clinic: Trans-Informing The Clinical Gaze To Counter Epistemic Violence, Diana E. Kuhl

Electronic Thesis and Dissertation Repository

This case study research (Patton, 2002, 2014; Flyvberg, 2006) has grown out of an awareness of deep resistance from the psy disciplines to trans-informed epistemologies as a source of legitimate knowledge (Tosh, 2015, 2016; Winters, 2008). It focuses on examining how the closure of The Gender Identity Clinic (GIC) for Children and Youth at the Centre for Addiction and Mental Health (CAMH) in Toronto, Ontario, Canada, signaled a paradigm shift from the ‘treatment model’ to the ‘affirmative model’ with respect to clinical approaches for supporting trans and gender diverse children and youth. As such the case study involved tracing the …

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 …

Using Meditation To Improve Measures Of Attention In Older Adults, Sabrina Ford

Electronic Thesis and Dissertation Repository

Age-related cognitive decline greatly impacts quality of life for older adults. Previous research has indicated that meditation may act as a neuroprotective factor to prevent age-related cognitive decline. This thesis sought to replicate previous findings and investigate if a four-week meditation intervention would improve sustained attention. Participants 60 years and older (n=27, 17 female) were recruited and assigned to a focused-attention (FA) meditation or relaxation group which met for four weeks, three times a week. Resting-state EEG was used to collect individual alpha peak frequency (iAPF) and frontal alpha asymmetry (FAA). The Sustained Attention to Response Task (SART) was also …

Using The Health Action Process Approach (Hapa) To Understand And Change Sedentary Behaviour In Office Workers: Effects On Motivation, Behaviour, And Health Outcomes, Andrew Scott Rollo

Electronic Thesis and Dissertation Repository

Sedentary behaviour (SB) is positively associated with all-cause mortality, as well as numerous chronic diseases, including fatal and non-fatal cardiovascular disease, type 2 diabetes, certain types of cancer, and metabolic syndrome. Interventions targeting reductions in sedentary time among office workers who are an at-risk population for high levels of SB are needed. The main objective of this dissertation was to contribute to the body of knowledge surrounding theory-based behavioural interventions targeting SB among office working adults. First, a systematic review of the literature (study 1, chapter 2) was conducted that highlighted important cognitive and motivational factors associated with SB, which …

Biofeedback Use In Sport, Kendra Nelson Ferguson

Electronic Thesis and Dissertation Repository

The general purpose of this dissertation was to examine the effects of biofeedback training on sport performance. This dissertation was divided into three studies. Study 1 qualitatively explored athletes’ perspectives of biofeedback post-intervention. Five varsity athletes were provided with a five-session biofeedback intervention training respiration rate, heart rate variability, and skin conductance. Following the intervention, an interview was conducted. Athletes perceived biofeedback to enhance self-regulation skills both in sport and academics, contributing to perceptions of superior performance.

To further examine perspectives of biofeedback training, Study 2 qualitatively explored mental performance consultants’ use of biofeedback and their perceptions of the tool. …

Optimizing Gait Outcomes In Parkinson's Disease With Auditory Cues: The Effects Of Synchronization, Groove, And Beat Perception Ability, Emily A. Ready

Electronic Thesis and Dissertation Repository

This dissertation explores a common, rehabilitative strategy for mitigating gait impairments in Parkinson’s disease (PD) called Rhythmic Auditory Stimulation (RAS). The effects of this intervention on gait in PD are well documented but highly variable, which poses difficulty for appropriate therapeutic application. Part of this variability may be related to individual musical abilities, such as beat perception accuracy, as most RAS interventions involve synchronizing with a beat. However, music is complex and variable. Therefore, factors inherent in the music itself may play a role in these differences, such as how much the music makes you want to move (groove), or …

Resedent Study- Reducing Sedentary Behaviour May Slow Cognitive Decline In Older Adults With Mild Cognitive Impairment: A Pilot Study, Kirsten B. Dillon

Electronic Thesis and Dissertation Repository

Physical activity (PA) has been shown to slow down dementia. Unfortunately, older adults spend most of their day in sedentary behaviours (SB). Breaking up prolonged bouts of sitting with intermittent bouts of light intensity PA may reduce glycemic variability in the brain; potentially mitigating cognitive decline. This study investigated how interrupting SB with 10 min bouts of light intensity PA 3x a day would affect mild to moderate cognitive impairment progression (primary outcome) in older adults residing in an assisted living facility. Participants (n=25) were assigned in clusters into a two arm 10-week single site pilot randomized controlled trial. Secondary …

Prevalence Of Moral Injury In Canadian Forces Members Deployed To Afghanistan, Kevin T. Hansen

Electronic Thesis and Dissertation Repository

Moral injury is a relatively new area of study within military mental health care, as such, prevalence estimates for both moral injury and exposure to potentially morally injurious events (PMIE; a moral injury precursor) are unknown for many of the world’s militaries. PMIE is commonly defined as the perpetrating, failing to prevent, witnessing, or learning about acts or events that transgress an individual’s deeply held moral belief(s). The primary purpose of this study was to estimate the prevalence of PMIE in a population of Canadian Armed Forces (CF) members who served in support of the recent mission to Afghanistan. How …

The Association Between Child And Youth Mental Health Service Urgency And Exposure To Childhood Interpersonal Trauma, Catherine Marshall

Electronic Thesis and Dissertation Repository

Children/youth with a history of maltreatment experience a variety of different developmental, psychiatric and health problems and ensuring there is streamline access to services is imperative to their recovery. Yet, there are few reports of standardized methods for directing and prioritizing risk for children seeking services. The current study,utilizingretrospective data collected from theinterRAIChild and Youth Mental Health Screener (ChYMH-S), aimed to address this gap and explore the relationship between childhood maltreatment and mental health screening outcomes. A sample of 4-18-year-olds (N= 19,645) was studied to explore how differences in maltreatment history, gender, and legal guardianship impacted service prioritization. The findings …
