Evaluation Of Therapist Modeling To Decrease Latency To Exercise Initiation, Darci L. Davis, Kayla Randall

Honors College Theses

Patients recovering from traumatic brain injury (TBI) or other adverse health events (e.g., hip surgery) often require physical therapy (PT) to restore baseline function. However, individuals with mild cognitive impairment (MCI) or dementia may have difficulty engaging in therapy due to deficits in attention, imitation skills, and motor performance. Enhancing participation in this population is essential for achieving functional recovery and return to baseline status. This study aimed to determine whether systematic model prompting could decrease latency to compliance and increase the level of completion of therapeutic exercises in short-term rehabilitation settings. A multiple-baseline single-case design with time-lagged and staggered …

No Consistent Evidence For Between- And Within-Person Associations Between Objective Social Media Screen Time And Body Image Dissatisfaction: Insights From A Daily Diary Study, Adalia Y. H. Goh, Andree Hartanto, K. T. A. Sandeeshwara Kasturiratna, Nadyanna M. Majeed

Research Collection School of Social Sciences

With the abundance of social media content that promotes unrealistic beauty standards, there are growing concerns about the potential negative impact of social media use on body image satisfaction. While some studies highlight negative associations, others present null effects, pointing to methodological limitations like biased and unreliable self-reported screen time measures and a focus on singular platforms. Addressing these gaps, our study employed a daily diary method to objectively measure social media screen time across six major platforms (Twitter, Reddit, TikTok, YouTube, Instagram, and Facebook), alongside daily body image dissatisfaction among 252 young adults (Mage = 21.67 years, 67.77% female) …

The Overlooked Dynamics Of Sibling Violence: Sociological Perspectives And Intervention Strategies, Rowland Edet

Department of Sociology: Faculty Publications

Sibling violence (SV) represents a pervasive yet underexplored dimension of family violence, encompassing physical, emotional, and psychological abuse. This paper critically examines the intersection of gender dynamics, societal norms, and family structures in shaping SV behaviors. Using social learning theory (SLT) as a foundational framework, the analysis explores how gendered expectations and traditional roles influence the prevalence and forms of aggression, with boys more likely to exhibit overt physical aggression and girls engaging in relational aggression. The paper critiques the deterministic tendencies of SLT, highlighting the agency of individuals in rejecting modeled behaviors, and incorporates intersectionality to address the interplay …

The Perceived Frequency And Effects Of Multilingual Communication In Youth And Adolescent Soccer, Simao M. Araujo

Theses and Dissertations (Comprehensive)

In professional soccer, the topic of multilingual communication has been widely researched; however, there appears to be a gap in the literature concerning how multilingual use is perceived by athletes and coaches at the youth and adolescent level of the sport. In the present study, male soccer athletes ages 10 to 18 years old and their coaches completed a questionnaire in which they rated both perceived frequency of use and perceived effects of using multilingual communication in youth and adolescent soccer. Specifically, these questionnaires elicited quantitative information regarding categories such as tactical advantages, words of encouragement, general expressions, and group …

Re-Imagining Care For Aging Disabled Adults, Caitlin L. Tizzard

Theses and Dissertations (Comprehensive)

In Ontario, the landscape of aging is shaped by ageist and ableist ideologies that view older disabled adults through the lens of decline and dependency. Much of the current discourse on aging focuses on reforming long-term care (LTC), reinforcing institutional and carceral responses both within policy and academic imagination. This qualitative study takes a different approach by asking participants how care for aging disabled adults can be reimagined beyond institutionalization. Grounded in intersectional feminist, disability justice and abolitionist praxis, and using a critical transformative paradigm, this research employed Appreciative Inquiry across three focus groups with four participants engaged in aging-related …

Terpenes Mitigate Thc-Induced Working Memory Deficits: Behavioural Evidence Of The Entourage Effect Using A 2-Component Operant Memory Task, Lara Mitchell

Theses and Dissertations (Comprehensive)

Most research on cannabis and cognitive function has focused on delta-9-tetrahydrocannabinol (THC). However, this approach overlooks the complex chemical composition of cannabis products consumed by the public, which often includes cannabidiol (CBD) and various terpenes. These additional constituents may interact with THC to modulate its effects, a phenomenon known as the entourage effect. While this theory has gained traction, experimental evidence for the cognitive impact of terpenes in combination with THC remains limited. This study aimed to assess whether terpenes can mitigate THC-induced cognitive deficits using a 2-Component Operant Memory task. Male Sprague-Dawley rats received intraperitoneal injections of either …

Exploring The Role Of Collective Narcissism And Ideology In Support For Reparations, Melih Can Sahin

Theses and Dissertations (Comprehensive)

Many societies with colonial histories have begun to grapple with their legacy of historical injustices and their ongoing consequences, leading to national apologies and sometimes consideration of reparations. In this context, it is important to understand the factors enhancing or impeding public support for reparations. This dissertation focused on the role of beliefs (ideology) and identity (collective narcissism) as predictors of support for reparations addressing historical injustices. Drawing from existing research, we expected that those higher in conservatism – and those higher in collective narcissism - would oppose reparations more strongly. We also examined the interaction between ideology and collective …

Co-Creation, Interpretations And Engagement With A Movement-Based Symbol For Climate Justice: A Qualitative Inquiry, Kai Reimer-Watts

Theses and Dissertations (Comprehensive)

The climate crisis demonstrates with complete clarity the need for massive systems-level changes towards far more sustainable societies. Global and local emissions need to decline rapidly to mitigate intensifying climate breakdown, accompanied by climate and sustainability solutions, to secure a far more stable, safe, and just future for all people and all life. Within these changes, engaging in our communities is essential to support and co-create broader solutions to help advance more sustainable societies, reduce negative impacts of a changing climate, and to move towards cultures and systems that recognize natural limits and centre care for people and planet.

Moral Identity: From Theory To Research, Jean Paul Lefebvre

Theses and Dissertations (Comprehensive)

Moral identity, often defined as the importance or centrality of moral values to a person’s sense of self, has long been understood to play an important role in moral functioning. However, critical gaps remain regarding its development, cross-context stability, and behavioural significance. This dissertation addresses these gaps in three empirical studies, providing new insights into the nature and function of moral identity across the lifespan and in daily life.

The first study (Chapter 2) explores developmental trends in moral identity, testing predictions from moral identity goal theory (Krettenauer, 2022). Using a cross-sectional sample spanning adolescence to old age, the study …

Grief On The Margins: The Death Of A Family Member To Substance Use, Adair Shaw

Theses and Dissertations (Comprehensive)

Despite Canada's high death rates from substance use, there is limited research on the sociopsychological impact on families, who often face stigma and disenfranchised grief. This study explores how family members make meaning of a substance-related death. Through qualitative inquiry, eleven family members were interviewed on their experience of grief from substance death. The imprint of losing a family member to mental illness and substance use is fraught with intergenerational grief, ambiguity, prolonged mental-emotional distress, and relationship challenges. Substance death was also associated with stigma, social withdrawal, and shame for many participants. However, grievers reconstructed the socially prescribed negative perceptions …

Repressed Memories And The Body Keeps The Score: Public Perceptions And Prevalence, Kris-Ann S. Anderson, Quincy C. Miller, Deryn Strange, Kamala London

Publications and Research

The “memory wars” resurgence has renewed debates over the validity of repressed memories. This revival appears linked to factors such as changing statutes of limitations, confusion about repression, and unchallenged social media content. In a nationally representative online survey of American adults (N = 1581), we examined (a) beliefs in repression and the body keeps the score, (b) the prevalence of recovered memory claims, and (c) the impact of question phrasing on recovered memory reporting. An overwhelming 94% of respondents expressed belief in repressed memory, and 77% endorsed the idea that the body keeps the score. Additionally, 3.6% (n = …

Preliminary Validity Of A Daily Functional Status Pain Assessment Tool, Wally R. Smith, Rehan Qayyum, Alexandra Ulbing, Margaret S. Guy, Daniel M. Sop, Yue May Zhang

Department of Medicine Faculty Publications

Objectives: Readiness for discharge for a sickle cell disease vaso-occlusive crisis is dictated by factors far beyond pain control, including physical function/activity. We therefore designed and tested a functional status-based pain assessment questionnaire in SCD patients hospitalized with vaso-occlusive crises.

Methods: Sickle cell disease patients on a preselected nursing unit rated 10 draft Functional status-Based Pain Assessment items of activities of daily living on a 5 point Likert scale (0-5) from “very easy” to “very difficult” daily on each day of their admission until discharge, at approximately the same time. Concurrently, they reported Numeric Rating Scale (0-10) pain intensity. …

Psychedelic Minimalism: The Case Against Music In Psychedelic Therapy Settings, Samir A. Nader

Department of Medicine Faculty Publications

[Introduction: reframing the role of setting] In recent years, renewed attention has been given to the centrality of set and setting in psychedelic-assisted therapy. The Reporting of Setting in Psychedelic Clinical Trials (ReSPCT) guidelines reflect an evolving consensus: therapeutic outcomes are not solely pharmacologically determined but are heavily shaped by both the environment and the psychological state of the participant (2). Within this evolving paradigm, music has assumed a privileged role, framed as a therapeutic constant, typically curated to be emotionally supportive or evocative, and especially emphasized during peak psychedelic states (3). The prevailing assumption is that music facilitates safety, …

The Combined Role Of Sexual Selection And Socioeconomic Environment In Explaining Everyday Risk-Taking Behavior In Human Males, Hannah Goodman, Cyril C. Grueter, David A. Coall

Research outputs 2022 to 2026

Sexual selection theory predicts that males, especially in their prime reproductive years, are more risk-prone than females. Risk-taking is a means to convey mate quality or “good genes” to members of the opposite sex or competitive ability to members of the same sex. Therefore, risk-taking should be more common in the presence of potential mates (intersexual selection or female choice) or in the presence of male competitors (intrasexual selection or male–male competition). Risk-taking can also be situated within a life history/ecological perspective, according to which environmental unpredictability promotes more present-oriented and risky behavioral strategies. Therefore, people living in areas of …

The Impacts Of Covid-19 Restrictions On Care-Givers Of People With Cognitive Impairment And Their Support Needs: A Mixed-Methods Systematic Review, Loretta Baldassar, Thi N. M. Nguyen, Bronte Jones, Catriona Stevens, Lukasz Krzyzowski, Silvia Lozeva, Simone Marino, Maria G. C. Du Plooy, Johanne Eldridge, Osvaldo P. Almeida, Manonita Ghosh

Research outputs 2022 to 2026

The COVID-19 pandemic and ensuing restrictions/lockdowns have caused significant physical and psychological consequences for people with cognitive impairment who are heavily dependent on their care-givers. However, little is known about the impact on care-givers, the factors that exacerbate their situation and what supports they need. The aims of this paper are threefold: (a) to examine the impact of COVID-19 physical restrictions on both formal and informal care-givers of people with cognitive impairment; (b) to identify attributing factors influencing this impact; and (c) to recognise their support needs. Further, this paper informs future research, policy and practice. Guided by the Joanna …

Talking About Relational Youth Work: Why Language Matters, Trudi Cooper, Tim Corney, Hilary Tierney, Jamie Gorman, John Sutcliffe

Research outputs 2022 to 2026

The literature on youth work emphasises the importance of ‘relationship’ to good practice, moreover, the characteristics of the youth-work relationship have been posited as a defining feature of youth work in the British-influenced tradition. Despite this, little attention is paid to the choice of language used to describe how professional youth workers relate to young people, or how language choices reflect political framing of youth work and of power relationships within their practice. Language choice has implications for how youth workers perceive their professional identity, for how accountability is construed, and for inter-professional working. In this article we undertake a …

Substance Misuse And Suicidal Behaviors In An Lgbtqia+ Sample: Examining The Buffering Effects Of Psychological Flexibility And Emotional Regulation, Mariano Ottone

College of Graduate Studies: Theses & Dissertations

Suicidal behaviors among LGBTQIA+ individuals, particularly in the context of substance misuse, present a significant area of exploration for mental health research and intervention. It is particularly important to evaluate factors capable of moderating this relationship, to promote more culturally affirming prevention models. This study aimed to explore the moderating roles of emotion regulation (ER) and psychological flexibility in the relationship between substance misuse and suicidal behaviors within the LGBTQIA+ community. Data were collected from 537 LGBTQIA+ adults through an online survey platform. Participants were asked to self-report on measures assessing the constructs of interest. The analysis focused on understanding …

How Does Psychopathology Impact The Trajectory From State To Trait Mindfulness?, Veronica O'Brien

College of Graduate Studies: Theses & Dissertations

Previous research has found that higher levels of trait mindfulness protect against psychopathology (e.g., Chiesa & Serretti, 2013; Desrosiers et al., 2013; Sevilla-Llewellyn-Jones et al., 2018); however, the research on state mindfulness and psychopathology is more mixed. These mixed findings suggest that some clients with higher levels of psychopathology may have greater difficulty engaging with mindfulness practice thereby hampering their progression towards trait mindfulness and its associated benefits. The present study sought to explore how psychopathology (i.e., anxiety, trauma, alcohol use, and depression) relates to the growth of state and trait mindfulness. The present study recruited 274 participants from a …

Perceived Credibility Of Allegations Of Sexual Assault Across Victim Race And Mental Health History, Liyah C. Morgan

College of Graduate Studies: Theses & Dissertations

Previous research examined the effect of victim gender and rape myth acceptance (RMA) on perceptions of victim credibility; however, little attention has been given to the impact of victim race and mental health history, and even fewer studies have explored the intersection of these two identities. The primary purpose of the current study was to identify factors affecting understanding of perceived credibility of victims of sexual assault, specifically in terms of victim race and mental health history. The study also examined the role of RMA on perceptions of credibility and explored participant attitudes related to color-blind racial attitudes and mental …

South Asian American Experiences Of Microaggressions And Wellbeing: The Moderating Role Of Social Support, Archita Birla

College of Graduate Studies: Theses & Dissertations

Although the South Asian American community is rapidly expanding in the United States (South Asian Americans Leading Together [SAALT], 2015), there remains a dearth of psychological research regarding the impacts on mental health and wellbeing affecting this diverse community. Racial microaggressions, or verbal or behavioral actions indicating hostile or negative attitudes toward marginalized individuals (Sue et al., 2007), negatively impact People of Color (POC) mental health and wellbeing (Forrest-Bank & Jenson, 2015a; Nadal, Wong, et al., 2015). Some research exists on South Asian American communities and microaggressions (Houshmand et al., 2014; Poolokasingham et al., 2014) but there is limited research …

Does Friend Groups’ Co-Rumination Explain Depression Homophily Among Undergraduate Women's Friendship Groups?, Alyssa D. C. Klas

College of Graduate Studies: Theses & Dissertations

The transition to college is a period known for changes in social support and increases in depression risk. Undergraduate women are particularly vulnerable to developing internalizing symptoms like depression in response to relational stressors and social norm pressures associated with college life. Co-rumination, defined as excessive and ongoing discussion about problems and emotionally distressing topics, both fosters connection and intimacy between friends and increases risk of depressive symptoms. Thus, relationships that are typically seen as buffers from depression may, paradoxically, contribute to risk when support-seeking becomes maladaptive. Most research on co-rumination’s effects is limited to friendship dyads. However, within larger …

Correlates Of Body Image And Physical Self-Concept, Rashuna Middleton

College of Graduate Studies: Theses & Dissertations

The growing overlap between social media and celebrity culture has played a significant role in shaping individuals' perceptions of body image and self-worth. This study explored the relationship between celebrity worship, problematic social media use, narcissism, physical self-concept, and body image among undergraduate psychology students. This study utilized the Celebrity Attitude Scale (CAS), the Narcissistic Personality Inventory (NPI), the Maladaptive Covert Narcissism Scale (MCNS), the Bergen Social Media Addiction Scale (BSMAS), the Body Influence Assessment Inventory (BIAI), the Self-Objectification Questionnaire (SOQ), and the Rosenberg Self-Esteem Scale (RSE). Findings indicated that vulnerable narcissism positively correlated with body image, whereas grandiose narcissism …

Effects Of Perinatal Exposure To Lipopolysaccharide And Acetaminophen On Learning In Adult Long-Evans Rats, Lucy A. Sivils

College of Graduate Studies: Theses & Dissertations

The present study investigated the individual and combined effects of elevated perinatal inflammation, oxidative stress caused by acetaminophen (APAP) exposure, or elevated inflammation and oxidative stress on adult learning behaviors in Long-Evans rats. While prior studies have examined these factors independently, the combined effects of inflammation and oxidative stress via APAP exposure during early development on learning-related behaviors remain unexplored. The present research aimed to address this gap by the analysis of potential long-term neurodevelopmental consequences of lipopolysaccharide (LPS)-induced inflammation and APAP-induced oxidative stress. LPS, APAP, or LPS + APAP was administered during the perinatal period: postnatal days (PD) 9, …

Place In Young Adults’ Alcohol Journeys, Lauren J. Gellatly, Cynthia M. Webster, Leanne Carter, Steve D’ Alessandro

Research outputs 2022 to 2026

Drinking alcohol is highly situational and depends in part on place. This research takes an interpretivist approach to explore different social and physical aspects of place that enable or inhibit young adults’ alcohol consumption journeys. In 14 asynchronous online forums, 47 Australian consumers aged 15–24 recalled a time when they drank too much and another when they chose to drink less. Starting with an inductive approach and moving to abductive reasoning, established qualitative techniques of categorisation, abstraction, dimensionalisation and comparison were used to interrogate the data. Results link moderate drinking to ‘smooth’ journeys typically occurring in single locations with more …

Appearances Can Be Deceiving: How Naturalistic Changes To Target Appearance Impact On Lineup-Based Decision-Making, Dominic T. Jordan, Adrian J. Scott, Donald M. Thomson

Research outputs 2022 to 2026

The present study examined the influence of appearance, procedure and position on identification decisions, post-decisional confidence ratings and estimates of discrimination and confidence-specific accuracy. Regarding appearance, the study examined the combined influence of three naturalistic changes that occur day-to-day (i.e. a reduction in cranial hair length, the removal of stubble, and a change of clothing), two of which have not been considered before in a lineup-decision context. Participants (N = 350) completed four experimental lineups which involved: viewing a target person, completing a brief distractor task, and making an identification decision and a post-decisional confidence rating from a photographic lineup. …

Resilience And Grit In Children And Adolescents With Autism Spectrum Disorder, Danielle Oehring

College of Graduate Studies: Theses & Dissertations

Resilience is the way in which an individual positively adapts to challenging or difficult life experiences. This process is marked by adjustments to external and internal demands through mental, emotional, and behavioral flexibility. Grit is perseverance and passion for long-term goals. Although grit and resilience have been researched in children and adolescents, there is a gap in the literature for how these variables relate to developmental disorders, like autism spectrum disorder, in children and adolescents. This study aimed to explore the relationship between autism spectrum disorder and internalizing and externalizing symptoms and whether grit and resilience moderates these relationships. Based …

The Moderating Effects Of Self-Compassion On The Relationship Between Shame And Depression In Military Populations, Sarah Foran

College of Graduate Studies: Theses & Dissertations

The U.S. Military has faced a continuous rise in mental health concerns reported by service members and veterans (Currier et al., 2017; Rosenheck & Fontana, 2007). Studies of military personnel have found that up to 15% of service members meet the criteria for experiencing depression (Shen et al., 2012). Often, individuals with military experience face numerous stressors that positively contribute to this experience of depression and feelings of shame (Bradbard et al., 2014; Litz et al., 2009). Military culture (often emphasizing shame related to mental health) has also been found to put military personnel at higher risk of experiencing depression …

Parent Social Validity Ratings Of Receiving Functional Communication Training, Shani Davies

Theses and Dissertations

This applied dissertation was designed to provide greater insight on parent and caregiver views and perceptions on participating in functional communication training. While extensive research exists regarding the effectiveness of functional communication training and parent training in general for children with Autism Spectrum Disorder, evidence on the social validity with respect to caregivers is lacking.

The researcher utilized evidenced-based social validity scales to explore parent/caregiver perceptions of receiving caregiver functional communication training, their perceived effectiveness of the treatment modality, and overall acceptance of the approach.

An analysis of the data revealed that parents’ overall perception was neutral regarding general views …
