Abstract:

It is well-established that alexithymia in adulthood is a critical risk factor for numerous negative mental health and well-being outcomes. Although this area of research has begun to receive interest in earlier developmental stages, significant methodological limitations have been noted with current measures of alexithymia for adolescence. As such, the aim of the current thesis was to provide empirical evidence on the psychometric strength of a new adolescent measure of alexithymia, the Toronto Alexithymia Scale – Adolescent Version (TAS-A). Study 1 examined the construct validity of the TAS-A in relation to self and informant reported emotional intelligence (EI), while study 2 examined the predictive validity of the TAS-A in relation to adolescent problematic gambling and academic achievement. Adolescents completed self-reports of alexithymia, EI, and gambling behaviour, parents completed informant reports regarding their child's EI, and academic records were obtained. Confirmatory factor analyses revealed significant relationships between adolescent alexithymia, and self and informant reported EI, indicating significant overlap in constructs. Adolescent alexithymia was also shown to be a significant predictor of problematic gambling and academic achievement; however, some interesting gender differences were observed (a pattern of results reported consistently in the adult alexithymia literature). Results are discussed in terms of methodological and clinical implications during the vulnerable developmental transition of adolescence.

Abstract:

Typically task interference is studied using reaching adaptation tasks (visuomotor rotation and/or force-field learning). Participants in these experiments are already experts at the base task (point-to-point, planar reaching) and their ability to adapt reaching to the imposed perturbation is studied. The pattern of data induced by the perturbation is used to make inferences about the nature and neural correlates of our learning and memory for reaching perturbations, specifically, and motor performance in general. We wanted to see if it is possible to demonstrate this same interference pattern using a novel vegetable-chopping task, where we can easily recreate natural performance settings using a task for which we can easily identify non-experts. Participants performed a chopping task in which they are asked to chop a sweet potato into 5 mm-wide slices, matching the beat of a metronome (120 bpm). Following this initial learning, participants were exposed to an interference condition. Participants then performed trials of the original task again. Interference was inferred if the second performance of the original task was impaired, compared to initial performance. Experiment 1 involved novice choppers, and either the force or frequency of chops was manipulated. Only the altered frequency task produced interference effects. In Experiment 2, competent and expert choppers had to manage either a faster or slower frequency. We found evidence for interference in competents, but not experts. These results support the idea that the vulnerability to interference of motor memory changes with practice, and so any inferences made about memory structure must take into account not only expert performance, but every level of skill.

Creator (cre): Tejpar, Lisa Morgan, Thesis advisor (ths): Nisbet, Elizabeth K.L., Degree committee member (dgc): Smith-Chant, Brenda, Degree granting institution (dgg): Trent University
Abstract:

Although a wealth of research supports nature's beneficial effects on well-being, a lack of attentiveness and appreciation for nature may prevent people from fully experiencing nature's benefits. A mindfulness-based nature intervention was tested across two studies to investigate whether gratitude and mindfulness can boost nature's effects for well-being. Students completed activities across a one-week (Study 1; N = 129) and two-week (Study 2; N = 130) intervention. Students in both studies experienced significant declines in positive and negative emotion over time. Study 1 did not show the expected increases in gratitude and connection to nature. Study 2 found that students who simply spent time in nature experienced fewer negative emotions and greater increases in trait gratitude than those who were asked to gratefully reflect on their natural surroundings. Both studies found positive correlations between trait gratitude, mindfulness, well- being and connection to nature. Implications and suggestions for future research are discussed.

Scripted Sexual Beliefs and Behaviours: From First to Recent Sexual Encounters

Type:
Names:
Creator (cre): Laverty, Erin, Thesis advisor (ths): Humphreys, Terry, Degree committee member (dgc): Navara, Geoff, Degree granting institution (dgg): Trent University
Abstract:

Sexual script theory suggests that sexual behaviours have social meaning, and that individuals perceive certain behaviours as normative and expected. Previous research has indicated that there is a common belief in a cultural sexual script for (hetero)sexual behaviour sequences (CSSHS). Study 1 compared perceived norms with behaviours in first ever penile-vaginal intercourse (PVI) sex events, as well as first and recent events with most recent partners. Many participants reported the CSSHS as typical, but few reported personal experiences that followed the CSSHS. Script adherence was not strongly related to physical pleasure. Study 2 found that committed relationships predicted greater female pleasure in first ever PVI sex. This link was mediated by communication during sexual activity. Results are discussed in the context of sexual script theory. Findings suggest that common scripted assumptions regarding PVI sex events should be reviewed for their value and representation of norms.

How Do We Let the Players Play and Keep Them Safe? The Issue of Problematic Beliefs in the Prevention of Concussion Injury

Type:
Names:
Creator (cre): Jorgensen, Michael, Thesis advisor (ths): O'Hagan, Fergal, Degree committee member (dgc): Lehmann, Hugo, Degree granting institution (dgg): Trent University
Abstract:

Athletes' concussion risk is part of a complex system of personal and contextual factors. This study differentiated athletes based on attitudes and intentions towards protective behaviours. A cross-sectional survey design was used to sample varsity athletes. Three intention response subgroups (indifferent, reactive, and proactive) were identified. The indifferent group (28%) reported little-to-no intent to engage in risk reduction behaviours. These athletes reported lower belief in the efficacy of concussion management behaviours and greater risk acceptance attitudes. The proactive group (32%) reported intent to actively reduce personal concussion risk through engaging in behaviours such as confronting aggressive opponents about the risk they pose to others. The reactive group (40%) only reported intent to engage in concussion management behaviours. Indifferent athletes had the highest likelihood of concussion exposure followed by reactive athletes. The proactive athletes had the lowest likelihood. Concussion programs must address beliefs and intentions towards protective behaviours to improve effectiveness.

Creator (cre): Morrison, Kristen, Thesis advisor (ths): Scharfe, Elaine, Degree committee member (dgc): Coughlan, Rory, Degree granting institution (dgg): Trent University
Abstract:

With the expansion of the internet, there are a number of opportunities to engage in cyber-bullying behaviour, however, to date, only a few studies have examined interpersonal predictors of cyber-bullying. The purpose of this research study was to explore relationship and personality factors associated with being a bully and/or a victim. The first goal of this study was to develop a comprehensive cyber-bullying measure. Results indicated three groups of cyber-bullying behaviours, including traditional (e.g. gossip); personal attack (e.g. negative remarks towards religion); and malicious behaviours (e.g. threats). Next, the associations between cyber-bullying and attachment, interdependence, and the dark triad of personality were examined. Analyses revealed that cyber-bullying was negatively associated with attachment security and interdependence and positively associated with insecurity and psychopathy. Discussion of the findings highlighted the importance of the dark triad in understanding predictors of cyber-bullying behaviours.

Abstract:

Strategies to reduce youth crime have been extensively researched and custody is not found to be effective. In the past, custody was a frequently used sentence, and while under the YOA the number of youth in custody was four times higher than that of adults in Canada. The use of custody sentences in Ontario has decreased in recent years, however; it remains above the Canadian average. Currently, alternatives to custody are also being implemented. This study aimed to gather lived experiences of those with firsthand experience in the youth justice system (offenders and staff). These individuals have working knowledge of effective practices for reducing recidivism. Eighteen semi-structured interviews were conducted. Interviews were coded and analysed using Interpretive Phenomenological Analysis. A number of themes emerged, including various views on the benefits of custody, the importance of relationships, challenges of the job and the need for increased focus on prevention.

It's a Mad, Mad, Mad, Mad World: a Critical Analysis Of The Perceptions And Lived Experiences of Mental Health and Illness In Kuwait

Abstract:

The purpose of this study was to understand the lived experiences of mental health and illness in Kuwait. Twenty-six participants were interviewed, including mental health professionals, family physicians, and service users. Findings suggest that inequality, oppression, and human rights violations may drive mental health issues in Kuwait. However, rather than addressing these factors, many healthcare providers are endorsing psychological testing and psychiatric medication, which may be resulting in the same iatrogenic (physician-induced) drug dependence that is seen in North America. An analysis of mainstream psychological theory, research and practice is provided, along with a bioethical critique of the World Health Organization's efforts to reduce the global 'burden' of mental disorders. This study cuts across disciplinary boundaries and 1) supports medical anthropologists' criticisms of the 'advancement' of global mental healthcare; 2) provides participant-driven, community-based alternatives that are specific to Kuwait; and 3) informs culturally defined notions of 'care' and 'ethics'.

Executive Function as a Predictor of Emotional, Behavioural, and Social Competence Problems in Children with Epilepsy

Type:
Names:
Creator (cre): Healy, Sarah, Thesis advisor (ths): Im-Bolter, Nancie, Degree committee member (dgc): Olds, Janet, Degree granting institution (dgg): Trent University
Abstract:

The study aimed to examine the association between different components of executive function (EF) and emotional, behavioural, and social competence problems (EBSP) in children with epilepsy. Although there is evidence of an association between EBSP and EF in typically developing children, little research has examined this relation in children with epilepsy. The sample comprised of 42 children with epilepsy, aged 6.0 to 18.1 years old. Results showed that EBSP were associated with EF in these children; however, different components of EF were related to different EBSP. Shifting was a significant predictor of emotional, behavioural, and social competence problems in children with epilepsy, whereas inhibition was a significant predictor of behavioural problems. This suggests that children with epilepsy, with different EF profiles may be at-risk for developing different types of problems. These results may aid researchers and clinicians with the development of new techniques to identify and treat children with EBSP.

Abstract:

The goal of the present study was to explore the overall discourse within media articles regarding Aboriginal health issues. The present research aimed to answer the following questions: What Aboriginal health issues are being discussed in the media? How are Aboriginal health issues being discussed in the media? And, does the media propagate power imbalances between Aboriginal and non-Aboriginal Canadians? A thematic analysis was conducted, coopting aspects of Critical Discourse Analysis (CDA) to assess media content. Four CDA devices were used: overlexicalisation, structural oppositions, nominalizations and functional nominations, and concessions and hedging. Results suggest that while there are disparities in health outcomes between Aboriginal and non-Aboriginal Canadians, it is not widely reported in the media. The thematic analysis of 208 articles revealed patterns of stereotypical ideologies and negative framing appearing in media articles, the creation of an us versus them narrative, and themes of out of sight, out of mind, criminalizing Aboriginal Canadians, politicizing health, and access to health services.
